Disclosure Of Significant Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies a. Basis of presentation These consolidated financial statements of the Partnership have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (or IFRS ) and using the accounting policies described below. The consolidated financial statements have been prepared under the assumption that the Partnership operates on a going concern basis and have been presented in U.S. dollars rounded to the nearest thousand unless otherwise indicated. In the opinion of management of the Partnership’s general partner, Altera Infrastructure GP L.L.C. (or the general partner ), these consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary to present fairly, in all material respects, the Partnership’s consolidated financial position, results of operations, changes in total equity and cash flows as at dates and for the periods presented. These consolidated financial statements were approved by management and authorized for issue on March 9, 2022. b. Going concern As at December 31, 2021, the Partnership had a working capital deficit of $276.4 million primarily relating to the scheduled maturities and repayments of $407.3 million of outstanding borrowings and the settlement of $34.7 million of other financial liabilities, primarily interest rate swaps, during the 12 months ending December 31, 2022, which amounts were classified as current liabilities as at December 31, 2021. The Partnership also anticipates making payments related to commitments to fund the vessel under construction through 2022 of $74.0 million; however, the Partnership has secured long-term financing related to the vessel. The working capital deficit of $276.4 million as at December 31, 2021 has increased from $230.5 million as at December 31, 2020. The increase in the working capital deficit was primarily due to a $95.2 million decrease in accounts and other receivable, net, an $84.1 million decrease in financial assets, a $44.8 million decrease in cash and cash equivalents, and a $45.2 million increase in borrowings. This was partially offset by a $164.3 million decrease in other financial liabilities, and a $37.0 million decrease in accounts payable and other. During the year ended December 31, 2021, the Partnership completed various measures to improve its debt maturity profile and enhance its liquidity and financial flexibility, including but not limited to exchanging $769.3 million of Brookfield debt with 2022 to 2024 maturities into debt with interest paid in kind and with a 2026 maturity, discontinuing distributions on the Series A, Series B and Series E Preferred Units, issuing $180.0 million of new 2025 bonds in the shuttle tanker segment and refinancing the Petrojarl I FPSO unit. See Notes 19, 21a and b, and 22 for additional information. While these measures improved the Partnership's liquidity position, the Partnership continues to explore its liquidity management opportunities and seek to improve and extend its debt profile. In addition to the successfully completed initiatives during 2021, it is still critical that the Partnership will need to obtain additional sources of financing, in addition to amounts generated from operations, to meet its obligations and commitments and minimum liquidity requirements under its financial covenants. These requirements include but are not limited to maintaining a minimum liquidity in an amount equal to the greater of $75 million and 5% of total debt as well as maintaining within the Partnership's wholly-owned subsidiary, Altera Shuttle Tankers L.L.C., a minimum liquidity in an amount equal to the greater of $35 million and 5% of total debt and a net debt to total capitalization ratio of no greater than 75%. Additional potential sources of financing that the Partnership is actively pursuing, during the one-year period to December 31, 2022, include entering into new debt facilities, borrowing additional amounts under existing facilities, the refinancing, extension or other amendments, including amendment of financial covenants, of certain borrowings and interest rate swaps, selling certain assets, seeking joint venture partners for the Partnership's business interests, enter into sale-leaseback agreements, increasing equity, and other potential liability management transactions. Additional potential sources of amounts generated from operations include the extensions and redeployments of existing assets, higher utilization of the operating fleet, increased rates for vessels operating in the spot market, increased oil price-based tariffs from certain FPSOs and working capital optimizations. The Partnership is actively pursuing or may pursue the financing initiatives described above, which it considers probable of completion based on the Partnership’s history of being able to raise and refinance borrowings for similar types of vessels and based on the Partnership's assessment of current conditions and estimated future conditions. The Partnership is in various stages of progression on these matters. See Note 31a for additional information. Based on the Partnership’s liquidity at the date of these consolidated financial statements, the liquidity it expects to generate from operations over the following year, and by incorporating the Partnership’s plans to raise additional liquidity that it considers probable of completion, the Partnership expects that it will have sufficient liquidity to enable the Partnership to continue as a going concern for at least the one-year period to December 31, 2022. c. Basis of consolidation The consolidated financial statements include the accounts of the Partnership and its consolidated subsidiaries, which are the entities over which the Partnership has control. An investor controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Non-controlling interests in the equity of the Partnership’s subsidiaries held by others are shown separately in equity in the consolidated statements of financial position. All intercompany balances, transactions, revenues and expenses are eliminated in full in these consolidated financial statements. d. Interests in other entities (i) Subsidiaries Subsidiaries are consolidated from the date of acquisition, being the date on which the Partnership obtained control, and continue to be consolidated until the date when control is lost. Non-controlling interests may be initially measured either at fair value or at the non-controlling interests’ proportionate share of the fair value of the acquiree’s identifiable net assets. The choice of measurement basis is made on an acquisition by acquisition basis. Subsequent to acquisition, the carrying amount of non-controlling interests is the amount of those interests at initial recognition plus the non-controlling interests’ share of subsequent changes in the Partnership's capital in addition to changes in ownership interests. Total comprehensive income (loss) is attributed to non-controlling interests, even if this results in the non-controlling interests having a deficit balance.

For non-wholly owned subsidiaries, the Partnership is exposed to variable returns from its involvement with the investee and has substantive decision making authority to affect the returns of its investment, as well as the power to direct the activities of the entities that can significantly impact the economic performance of the entity. (ii) Joint ventures Joint ventures are joint arrangements whereby the parties that have joint control of the arrangement have rights to the net assets of the joint arrangement. Joint control is the contractually agreed sharing of control over an arrangement, which exists when decisions about the relevant activities require unanimous consent of the parties sharing control. The Partnership accounts for joint ventures using the equity method of accounting within equity-accounted investments in the consolidated statements of financial position. Interests in joint ventures accounted for using the equity method are initially recognized at cost. Subsequent to initial recognition, the carrying value of the Partnership’s interest in a joint venture is adjusted for the Partnership’s share of comprehensive income and distributions of the investee. Profit and losses resulting from transactions with a joint venture are recognized in the consolidated financial statements based on the interests of unrelated investors in the investee. The carrying value of joint ventures is assessed for impairment at each reporting date. Impairment losses on equity-accounted investments may be subsequently reversed in net income. Further information on the impairment of long-lived assets is available in Note 2(l).

Cayman Islands 50% e. Foreign currency translation The U.S. dollar is the functional and presentation currency of the Partnership. The Partnership’s vessels operate in international shipping markets in which substantially all income and expenses are settled in U.S. dollars. In addition, the Partnership's most significant assets, its vessels and equipment, are bought and sold in U.S. dollars and the Partnership's most significant liabilities, its commercial bank borrowings, are denominated in U.S. dollars. Foreign currency denominated monetary assets and liabilities are translated using the rate of exchange prevailing at the reporting date and non-monetary assets and liabilities are measured at historic cost and are translated at the rate of exchange at the transaction date. Foreign currency denominated revenues and expenses are measured at average rates during the period. Gains or losses on translation of these items are included in foreign currency exchange gain (loss) in the consolidated statements of income (loss). f. Cash and cash equivalents Cash and cash equivalents include cash on hand, non-restricted deposits and short-term investments with original maturities of three months or less. g. Accounts and other receivable, net Accounts and other receivable, net includes trade receivables and other unbilled receivables. Accounts and other receivable, net, except for trade receivables, are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less any allowance for expected credit losses. Trade receivables are recognized initially at their transaction price. h. Inventory Inventories are the materials or supplies consumed in the rendering of services. Inventory is valued at the lower of cost and net realizable value. Cost is determined using specific identification where possible and practicable or using the first-in, first-out method. Costs include direct and indirect expenditures incurred in bringing the inventory to its existing condition and location. Net realizable value represents the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale. The following table presents the details of the Partnership's inventory as at December 31, 2021 and 2020: December 31, 2021 December 31, 2020 $ $ Fuel oil 23,203 13,528 Materials and consumables 3,398 2,780 Total inventory 26,601 16,308 i. Related party transactions In the normal course of operations, the Partnership enters into various transactions with related parties, which have been measured at their fair value, which generally is the agreed upon exchange value and are recognized in the consolidated financial statements. Related party transactions are further described in Note 21. Related Party Borrowings Reclassification The accounting policy elected historically by the Partnership has reflected its long-term debt within two line items, Borrowings and Due to related parties. Borrowings has included publicly listed debt held by third parties and by Brookfield. The related party component of publicly listed Borrowings has been historically disclosed in the notes to the financial statements. On August 27, 2021, the Partnership completed a refinancing with Brookfield (or the Brookfield Exchanges ) (see Note 21a for additional information) and voluntarily revised the Partnership's accounting policy to classify all debt held by Brookfield, regardless of the nature of the instrument as Due to related parties. The Partnership believes it is more relevant to show all related party debt on the same financial statement line item. The Partnership has reflected this change retrospectively by restating its comparative consolidated statement of financial position. Following the change, debt will continue to be included in two line items, Borrowings, which will include only debt held by third-party counterparties and Due to related parties, which will include all debt where Brookfield or other affiliates are the ultimate counterparty, regardless of whether a debt instrument is publicly listed. Additionally, all accrued interest on related party debt will be reflected within the Due to related parties line item rather than within Accounts payable and other, as previously reported. The following tables provides a reconciliation of the resulting reclassifications directly related to the change in accounting policy discussed above to the Partnership's consolidated statements of financial position: As at As at December 31, 2020 December 31, 2020 As Previously Reported Reclassifications Restated $ $ $ Accounts payable and other 302,414 (16,119) 286,295 Due to related parties 7 16,119 16,126 Total current liabilities 302,421 — 302,421 Borrowings 2,808,898 (411,260) 2,397,638 Due to related parties 194,628 411,260 605,888 Total non-current liabilities 3,003,526 — 3,003,526 Total liabilities 3,305,947 — 3,305,947 As at As at December 31, 2019 January 1, 2020 As Previously Reported Reclassifications Restated $ $ $ Accounts payable and other 272,618 (16,504) 256,114 Due to related parties 21,306 16,504 37,810 Total current liabilities 293,924 — 293,924 Borrowings 2,831,274 (423,625) 2,407,649 Due to related parties — 423,625 423,625 Total non-current liabilities 2,831,274 — 2,831,274 Total liabilities 3,125,198 — 3,125,198 j. Vessels and equipment Vessels and equipment are measured at cost less accumulated depreciation and accumulated impairment losses, if any. Cost includes expenditures that are directly attributable to the acquisition of the asset including the cost of materials and direct labor, any other costs directly attributable to bringing the assets to a working condition for their intended use, and the cost of dismantling and removing the items and restoring the site on which they are located. All pre-delivery costs incurred during the construction of vessels and equipment, including interest, supervision and technical costs, are capitalized. The acquisition cost and all costs incurred to restore used vessels and equipment purchased by the Partnership to the standard required to service the Partnership’s customers are capitalized. Depreciation of an asset commences when it is available for use. Vessels and equipment are depreciated for each component of the asset classes as follows: Component Estimated Useful Life Dry docks and Overhauls 2.5 - 5 years Capital Modifications (1) 3 - 20 years Vessels and Equipment (2) 9 - 35 years (1) Includes field and contract specific equipment for the Partnership's FPSO units and FSO units, capital upgrades for the Partnership's shuttle tankers and mid-life refurbishments for the Partnership's UMS. (2) Certain of the Partnership's FPSO units and FSO units have undergone conversions or capital upgrades prior to commencing operations under their current contracts. The estimated useful lives of such vessels is generally substantially lower than that of a comparable newbuilding vessel. For a newbuilding vessel, the Partnership uses an estimated useful life of 20 to 25 years for its FPSO units, 20 years for its shuttle tankers, 35 years for its UMS and 25 years for its towage and offshore installation (or Towage ) vessels. The estimated useful life of the Partnership's FSO units are generally the contract term for the unit, inclusive of extension options. Depreciation on vessels and equipment is calculated on a straight-line basis so as to write-off the net cost of each asset over its expected useful life to its estimated residual value. Residual value of the vessel hull is estimated as the lightweight tonnage of each vessel multiplied by recycling value per ton. The estimated useful lives, residual values and depreciation methods are reviewed annually, with the effect of any changes recognized on a prospective basis. Vessel capital modifications include the addition of new equipment or can encompass various modifications to the vessel which are aimed at improving or increasing the operational efficiency and functionality of the asset. This type of expenditure is amortized over the estimated useful life of the modification. Expenditures covering recurring routine repairs or maintenance are expensed as incurred. Generally, the Partnership dry docks each shuttle tanker or towage vessel every two and a half to five years, depending on the nature of work and external requirements. The vessels are required to undergo planned dry docking for replacement of certain components, major repairs and major maintenance of other components, which cannot be carried out while the vessels are operating. The Partnership capitalizes a portion of the costs incurred during dry docking and amortizes those costs on a straight-line basis from the completion of a dry docking over the estimated useful life of the dry dock, which is generally until the commencement of the subsequent dry dock. Included in capitalized dry docking are costs incurred as part of the dry docking to meet regulatory requirements, or expenditures that either add economic life to the vessel, increase the vessel’s earning capacity or improve the vessel’s operating efficiency. A portion of the cost of acquiring a new vessel is allocated to the components expected to be replaced or refurbished at the next dry-docking. The Partnership expenses costs related to routine repairs and maintenance performed during dry docking that do not improve operating efficiency or extend the useful lives of the assets. Advances on newbuilding contracts consists of prepayments related to newbuilding contracts for vessels and equipment not yet delivered to the Partnership and include the share of borrowing costs that are directly attributable to the acquisition of the underlying vessel. When a vessel is delivered, the prepaid amount is reallocated to Vessels and equipment. k. Right-of-use assets and lease obligations The Partnership assesses whether a contract is, or contains, a lease at inception of the contract. A right-of-use asset and corresponding lease liability is recognized at the lease commencement date for contracts that are, or contain, a lease component, except for short-term leases and leases of low value. Agreements to charter in vessels and to lease land and buildings for which the Partnership substantially has the right to control the asset for a period of time in exchange for consideration are recognized in the consolidated statements of financial position as right-of-use assets within Other assets and are initially measured at cost, which comprises the initial amount of the lease liabilities adjusted for any lease payments made at or before the commencement date. Subsequently, the right-of-use assets are measured at cost less accumulated depreciation and impairment losses, if any. The right-of-use assets are depreciated on a straight-line basis over the lesser of the lease term or remaining life of the underlying asset, depending on the lease terms. The Partnership charters in vessels from other vessel owners on time-charter contracts, whereby the vessel owner provides use of the vessel to the Partnership, as well as operates the vessel for the Partnership. A time-charter contract is typically for a fixed period of time, although in certain cases the Partnership may have the option to extend the charter. The Partnership will typically pay the owner a daily hire rate that is fixed over the duration of the charter. The Partnership is generally not required to pay the daily hire rate during periods the vessel is not able to operate. The Partnership has determined that all of its time-charter-in contracts contain both a lease component (lease of the vessel) and a non-lease component (operation of the vessel). The Partnership has allocated the contract consideration between the lease component and non-lease component on a relative standalone selling price basis. Given that there are no observable standalone selling prices for either of these two components, judgment is required in determining the standalone selling price of each component. The standalone selling price of the non-lease component has been determined using a cost-plus approach, whereby the Partnership estimates the cost to operate the vessel using cost benchmarking studies prepared by a third party, when available, or internal estimates when not available, plus a profit margin. The standalone selling price of the lease component has been determined using an adjusted market approach, whereby the Partnership calculates a rate excluding the operating component based on a market time-charter rate from published broker estimates, when available, or internal estimates when not available. The discount rate of the lease is determined using the Partnership’s incremental borrowing rate, which is based on the fixed interest rate the Partnership could obtain when entering into a secured loan facility of similar term. The Partnership has elected to recognize the lease payments of short-term leases in profit or loss on a straight-line basis over the lease term and variable lease payments not dependent on a rate or index in the period in which the obligation for those payments is incurred, which is consistent with the recognition of payment for the non-lease component. Short-term leases are leases with an original term of one year or less, excluding those leases with an option to extend the lease for greater than one year or an option to purchase the underlying asset, that the lessee is reasonably certain to exercise. The corresponding lease obligation is recognized as a liability in the consolidated statements of financial position under Accounts payable and other and initially measured at the present value of the outstanding lease payments at the commencement date. The Partnership recognizes the lease payments for leases of low value as an operating expense on a straight-line basis over the term of the lease. l. Asset impairment At each reporting date the Partnership assesses whether there is any indication that assets or cash generating units, relating specifically to its vessels and equipment and right-of use-assets, are impaired. This assessment includes a review of internal and external factors which includes, but is not limited to, changes in the technological, political, economic or legal environments in which the Partnership operates, structural changes in the industry, changes in the level of demand, physical damage and obsolescence due to technological changes. The Partnership has determined that, for impairment purposes, each individual vessel, except for the Partnership's contract of affreightment (or CoA ) vessels, is a cash generating unit. This is due to the fact that the cash inflows from an individual vessel operating in the CoA fleet are not largely independent of the cash inflows from other vessels operating in the CoA fleet, i.e., the individual vessels are not the smallest identifiable group and therefore it is concluded that the CoA fleet is a single cash generating unit. An impairment is recognized if the recoverable amount, determined as the higher of the estimated fair value less costs of disposal or the value in use, is less than the carrying value of the asset or cash generating unit. In cases where an active second-hand sale and purchase market does not exist, the Partnership uses a discounted cash flow approach to estimate the fair value of its vessel and equipment. In cases where an active second-hand sale and purchase market exists, an appraised value is used to estimate the fair value of the vessel and equipment. An appraised value is generally the amount the Partnership would expect to receive if it were to sell the vessel. Such appraisal is normally completed by the Partnership. The value in use is the present value of the future cash flows that the Partnership expects to derive from the asset or cash generating unit. The projections of future cash flows take into account the relevant operating plans and management’s best estimate of the most probable set of conditions anticipated to prevail. At each reporting date the Partnership assesses whether there is any indication that an impairment loss may have decreased. Where an impairment loss subsequently reverses, the carrying amount of the asset or cash generating unit is increased to the revised estimate. m. Goodwill Goodwill represents the excess of the price paid for the acquisition of a business over the fair value of the net tangible and intangible assets and liabilities acquired. Goodwill is allocated to the cash generating unit or units to which it relates. The Partnership identifies cash generating units as identifiable groups of assets whose cash inflows largely independent of the cash inflows from other assets or groups of assets. The Partnership has identified the shuttle tanker segment as the group of cash generating units to which the Partnership's goodwill relates. Goodwill is evaluated for impairment on an annual basis or more frequently if an event occurs or circumstances change that would indicate that the recoverable amount of a reporting unit was below its carrying value. Impairment is determined for goodwill by assessing if the carrying value of a cash generating unit, including the allocated goodwill, exceeds its recoverable amount determined as the greater of the estimated fair value less costs of disposal or the value in use. Impairment losses recognized in respect of a cash generating unit are first allocated to the carrying value of goodwill and any excess is allocated to the carrying amount of assets in the cash generating unit. Any goodwill impairment is charged to Impairment expense, net on the consolidated statements of income (loss) in the period in which the impairment is identified. Impairment losses on goodwill are not subsequently reversed. n. Revenues Each vessel charter may, depending on its terms, contain a lease component, a non-lease component or both. Revenues that are fixed on or prior to the commencement of the contract are recognized by the Partnership on a straight-line basis daily over the term of the contract

Disclosure Of Fair Value Of Financial Instruments [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In the absence of an active market, fair values are determined based on prevailing market rates for instruments with similar characteristics and risk profiles, or internal or external valuation models, such as discounted cash flow analysis, maximizing observable market inputs. Fair values determined using valuation models require the use of assumptions concerning the amount and timing of estimated future cash flows and discount rates. In determining those assumptions, the Partnership looks primarily to external readily observable market inputs such as interest rate yield curves and price and rate volatilities as applicable. Financial instruments classified as fair value through profit or loss (or FVTPL ) are carried at fair value in the consolidated statements of financial position and changes in fair values are recognized in profit or loss. The following tables provide the details of financial instruments and their associated classifications as at December 31, 2021 and 2020: December 31, 2021 December 31, 2020 Measurement Basis FVTPL Amortized cost Total FVTPL Amortized cost Total Financial assets Cash and cash equivalents — 190,942 190,942 — 235,734 235,734 Financial assets (current and non-current) 325 64,815 65,140 6,497 133,389 139,886 Accounts and other receivable, net (current and non-current) (1) — 120,940 120,940 — 212,316 212,316 Due from related parties (current and non-current) — 978 978 — 9,980 9,980 Other assets (current and non-current) (2) — 53,158 53,158 — 59,905 59,905 Total 325 430,833 431,158 6,497 651,324 657,821 Financial liabilities Accounts payable and other (3) — 62,414 62,414 — 81,850 81,850 Other financial liabilities (current and non- current) (4) 24,229 199,108 223,337 203,597 139,738 343,335 Due to related parties (current and non-current) — 797,432 797,432 — 622,014 622,014 Borrowings (current and non-current) — 2,464,027 2,464,027 — 2,759,717 2,759,717 Total 24,229 3,522,981 3,547,210 203,597 3,603,319 3,806,916 (1) Excludes tax receivable of $6.5 million as at December 31, 2021 (December 31, 2020 - $10.3 million).

(4) Includes derivative instruments, obligations relating to leases and other financial liabilities. Refer to Note 18 below. Included in cash and cash equivalents as at December 31, 2021 is $190.9 million of cash (December 31, 2020 - $235.7 million) and $nil of cash equivalents (December 31, 2020 - $nil). The fair value of all financial assets and liabilities as at December 31, 2021 approximated their carrying values, with the exception of the borrowings, where fair value which was determined using Level 1 and Level 2 inputs and resulted in a fair value of $2,362 million (December 31, 2020: $2,753 million) versus a carrying value of $2,464 million (December 31, 2020: $2,760 million). The fair value of the Partnership’s fixed-rate and variable-rate long-term debt is either based on quoted market prices or estimated using discounted cash flow analysis based on rates currently available for debt with similar terms and remaining maturities and the current credit worthiness of the Partnership. In addition, within the December 31, 2020 Due to related parties (current and non-current) balance shown above $411.3 million of the outstanding senior unsecured bonds held by Brookfield were fair valued using Level 1 and Level 2 inputs and resulted in a fair value of $351.4 million.

Derivative Financial Instruments The Partnership’s activities expose it to a variety of financial risks, including liquidity risk, interest rate risk, foreign currency risk and credit risk. The Partnership selectively uses derivative financial instruments to manage certain of these risks. The aggregate amount of the Partnership's derivative financial instrument positions is as follows: December 31, 2021 December 31, 2020 Financial Asset Financial Liability Financial Asset Financial Liability $ $ $ $ Interest rate swaps — 23,470 — 203,597 Foreign currency forward contracts 325 758 6,497 — Total 325 24,228 6,497 203,597 Total current 325 23,688 6,497 189,647 Total non-current — 541 — 13,950 Interest Rate Risk The Partnership enters into interest rate swaps, which exchange a receipt of floating interest for a payment of fixed interest, to reduce the Partnership’s exposure to interest rate variability on its outstanding floating-rate debt. The Partnership has not designated, for accounting purposes, any of its interest rate swaps held during the years ended December 31, 2021, 2020 and 2019 as hedges of variable rate debt. Certain of the Partnership's interest rate swaps are secured by vessels. As at December 31, 2021, the Partnership and its consolidated subsidiaries were committed to the following interest rate swap agreements: Interest Notional Fair Value / Carrying Amount of Asset (Liability) (1) $ Weighted- Fixed Interest Rate (%) (2) U.S. Dollar-denominated interest rate swaps (3)(4)(5) LIBOR 152,903 (6,715) 0.55 2.6 % U.S. Dollar-denominated interest rate swaps (6)(7)(8) LIBOR 388,745 (16,755) 0.75 2.5 % 541,648 (23,470) (1) Excludes accrued interest of $1.8 million. (2) Excludes the margin the Partnership pays on its variable-rate debt, which as at December 31, 2021, ranged between 1.1% and 6.5%. (3) Notional amount remains constant over the term of the swap, unless the swap is partially terminated. (4) Includes one interest rate swap, which as at December 31, 2021, had a total current notional amount of $100.0 million and a total fair value liability of $1.3 million. This interest rate swap is due to terminate in the third quarter of 2022. (5) Includes one interest rate swap, which as at December 31, 2021, had a total current notional amount of $52.9 million and a total fair value liability of $5.9 million. This interest rate swap includes mandatory termination provisions which terminate this interest rate swap in the first quarter of 2022. (6) Principal amount reduces quarterly or semi-annually. (7) Includes one interest rate swap, which as at December 31, 2021, had a total current notional amount of $78.0 million and a total fair value liability of $11.2 million. This interest rate swap includes mandatory termination provisions which terminate this interest rate swap in the first quarter of 2022. (8) Includes three interest rate swaps, which as at December 31, 2021, had a total current notional amount of $285.3 million and a total fair value liability of $6.0 million. These interest rate swaps include mandatory termination provisions which terminate these interest rate swaps in the second quarter of 2022. During the year ended December 31, 2021, the effective portion of previously designated and qualifying cash flow hedges recorded in accumulated other comprehensive income during the term of the hedging relationship and reclassified to earnings and reported in interest expense was a gain of $0.8 million (December 31, 2020 - gain of $0.8 million, December 31, 2019 - gain of $0.7 million). As at December 31, 2021, the Partnership had multiple interest rate swaps and foreign currency forward contracts governed by certain master agreements. The fair value of these derivatives is presented on a gross basis in the Partnership’s consolidated statements of financial position. As at December 31, 2021, these derivatives had an aggregate fair value asset amount of $0.3 million and an aggregate fair value liability amount of $0.8 million (December 31, 2020 - an aggregate fair value asset amount of $6.5 million and an aggregate fair value liability amount of $147.5 million).

The Partnership is exposed to credit loss in the event of non-performance by the counterparties, all of which are financial institutions, to the foreign currency forward contracts and the interest rate swap agreements. Other Information Regarding Derivative Financial Instruments Series D Detachable Warrants In June 2016, the Partnership issued 4,500,000 warrants with an exercise price of $4.55 per unit (the $4.55 Warrants ) and 2,250,000 warrants with an exercise price of $6.05 per unit (the $6.05 Warrants ) (collectively, the Warrants ) to a group of investors and subsidiaries of Teekay Corporation. In September 2017, the exercise price of the $6.05 Warrants was reduced to $4.55 per unit. As at December 31, 2019, the Warrants had a seven-year term and were exercisable any time after six months following their issuance date. The Warrants could be settled either in cash or common units at the Partnership’s option. The Warrants were classified as derivative financial instruments in the Partnership's consolidated statement of financial position with 6,750,000 Warrants outstanding at December 31, 2019. On January 22, 2020, Brookfield completed the Merger (see Note 22 for additional information) of all of the outstanding publicly held and listed common units representing the Partnership's limited partner interests held by parties other than Brookfield. As a result of this transaction, and the fact that the exercise price of each of the outstanding Warrants exceeded the cash consideration of $1.55 per common unit, each of the Warrants was automatically canceled and ceased to exist. No consideration was delivered in respect thereof. As at December 31, 2019, as a result of the pending Merger, the fair value measurement of the Warrants using Level 3 unobservable inputs was $nil. Brookfield Warrants In September 2017, the Partnership issued to Brookfield and Teekay Corporation 62.4 million and 3.1 million warrants, respectively (the Brookfield Warrants ), with each warrant exercisable for one common unit. As part of a separate transaction, Brookfield concurrently transferred 11.4 million Brookfield Warrants to Teekay Corporation. The Brookfield Warrants entitled the holders to acquire one common unit for each Brookfield Warrant for an exercise price of $0.01 per common unit, which was exercisable until September 25, 2024 if the Partnership's common unit volume-weighted average price was equal to or greater than $4.00 per common unit for 10 consecutive trading days. In July 2018, Brookfield, through an affiliate, exercised its option to acquire an additional 2% of ownership interests in the Partnership's general partner from an affiliate of Teekay Corporation in exchange for 1.0 million Brookfield Warrants. In May 2019, Brookfield acquired all of Teekay Corporation's remaining interests in the Partnership including 17.3 million common unit equivalent warrants. As at December 31, 2019, Brookfield held all of the 65.5 million Brookfield Warrants. On January 22, 2020, Brookfield completed the Merger (see Note 22 for additional information) of all of the outstanding publicly held and listed common units representing the Partnership's limited partner interests held by parties other than Brookfield. As a result of this transaction, and the fact that the exercise price of each of the outstanding Brookfield Warrant exceeded the cash consideration of $1.55 per common unit, each of the Brookfield Warrants was automatically canceled and ceased to exist. No consideration was delivered in respect thereof. As at December 31, 2019, as a result of the pending Merger, the fair value measurement of the Brookfield Warrants using Level 3 unobservable inputs was $nil.

For the units within the FPSO, FSO and UMS segments, there are uncertainties in the assumptions for redeployments where there is no signed contract in place. When estimating the recoverable amount, the Partnership makes assumptions for the uncontracted cash flows over the useful life for each unit. These are estimated based on the Partnership's market knowledge, experience and return on invested capital. These assumptions are used to create scenarios with different cash flows for each unit. Based on the attractiveness of the various assets, the assumptions can include extensions on current contracts, new contracts, sale or a recycling option. The recoverable amount is a weighted average of all the scenarios. As at December 31, 2021, due to uncertainty in the redeployment market for FPSO, FSO and UMS units and short remaining contract lengths, the Partnership identified impairment triggers for all of its FPSO fleet, one of its FSO units, and its one UMS unit. The asset values of the Voyageur Spirit FPSO and the Piranema Spirit FPSO were impaired as at December 31, 2021. For the remaining FPSO units, one FSO unit, and one UMS unit, the tests did not result in a recoverable value lower than the carrying value and were therefore not impaired. The Partnership's impairment tests are sensitive to changes in key assumptions such as discount rate, assumed contract rates and the weight applied to the various scenarios. For the remaining FPSO units, one FSO unit, and one UMS unit for-which the impairment tests as at December 31, 2021 did not result in an impairment: • An increase of 0.5% for the discount rate would result in an impairment of $21.2 million. • An additional one-year before redeployment of the units in the weighted scenarios would result in an impairment of $66.7 million. • A 10% reduction in rate/sales proceeds from the weighted scenarios on the same units would result in an impairment of $52.3 million. As at December 31, 2021, the Partnership had four vessels and equipment, with a carrying value of $103.1 million, which were in lay-up (one of which was classified as held for sale - $5.8 million) (December 31, 2020 - five vessels and equipment with a carrying value of $190.2 million (two of which were classified as held for sale - $4.4 million)).

For the units within the FPSO, FSO and UMS segments, there are uncertainties in the assumptions for redeployments where there is no signed contract in place. When estimating the recoverable amount, the Partnership makes assumptions for the uncontracted cash flows over the useful life for each unit. These are estimated based on the Partnership's market knowledge, experience and return on invested capital. These assumptions are used to create scenarios with different cash flows for each unit. Based on the attractiveness of the various assets, the assumptions can include extensions on current contracts, new contracts, sale or a recycling option. The recoverable amount is a weighted average of all the scenarios. As at December 31, 2021, due to uncertainty in the redeployment market for FPSO, FSO and UMS units and short remaining contract lengths, the Partnership identified impairment triggers for all of its FPSO fleet, one of its FSO units, and its one UMS unit. The asset values of the Voyageur Spirit FPSO and the Piranema Spirit FPSO were impaired as at December 31, 2021. For the remaining FPSO units, one FSO unit, and one UMS unit, the tests did not result in a recoverable value lower than the carrying value and were therefore not impaired. The Partnership's impairment tests are sensitive to changes in key assumptions such as discount rate, assumed contract rates and the weight applied to the various scenarios. For the remaining FPSO units, one FSO unit, and one UMS unit for-which the impairment tests as at December 31, 2021 did not result in an impairment: • An increase of 0.5% for the discount rate would result in an impairment of $21.2 million. • An additional one-year before redeployment of the units in the weighted scenarios would result in an impairment of $66.7 million. • A 10% reduction in rate/sales proceeds from the weighted scenarios on the same units would result in an impairment of $52.3 million. As at December 31, 2021, the Partnership had four vessels and equipment, with a carrying value of $103.1 million, which were in lay-up (one of which was classified as held for sale - $5.8 million) (December 31, 2020 - five vessels and equipment with a carrying value of $190.2 million (two of which were classified as held for sale - $4.4 million)).

For the units within the FPSO, FSO and UMS segments, there are uncertainties in the assumptions for redeployments where there is no signed contract in place. When estimating the recoverable amount, the Partnership makes assumptions for the uncontracted cash flows over the useful life for each unit. These are estimated based on the Partnership's market knowledge, experience and return on invested capital. These assumptions are used to create scenarios with different cash flows for each unit. Based on the attractiveness of the various assets, the assumptions can include extensions on current contracts, new contracts, sale or a recycling option. The recoverable amount is a weighted average of all the scenarios. As at December 31, 2021, due to uncertainty in the redeployment market for FPSO, FSO and UMS units and short remaining contract lengths, the Partnership identified impairment triggers for all of its FPSO fleet, one of its FSO units, and its one UMS unit. The asset values of the Voyageur Spirit FPSO and the Piranema Spirit FPSO were impaired as at December 31, 2021. For the remaining FPSO units, one FSO unit, and one UMS unit, the tests did not result in a recoverable value lower than the carrying value and were therefore not impaired. The Partnership's impairment tests are sensitive to changes in key assumptions such as discount rate, assumed contract rates and the weight applied to the various scenarios. For the remaining FPSO units, one FSO unit, and one UMS unit for-which the impairment tests as at December 31, 2021 did not result in an impairment: • An increase of 0.5% for the discount rate would result in an impairment of $21.2 million. • An additional one-year before redeployment of the units in the weighted scenarios would result in an impairment of $66.7 million. • A 10% reduction in rate/sales proceeds from the weighted scenarios on the same units would result in an impairment of $52.3 million. As at December 31, 2021, the Partnership had four vessels and equipment, with a carrying value of $103.1 million, which were in lay-up (one of which was classified as held for sale - $5.8 million) (December 31, 2020 - five vessels and equipment with a carrying value of $190.2 million (two of which were classified as held for sale - $4.4 million)).

Goodwill

Goodwill	12 Months Ended

Disclosure Of Goodwill [Abstract]
Goodwill	Goodwill The Partnership has identified the Shuttle Tanker segment as the group of cash generating units to which the Partnership's goodwill relates. The carrying amount of goodwill for the Shuttle Tanker segment was $127.1 million as at December 31, 2021 and 2020. The Partnership conducted its annual goodwill impairment evaluation during 2021 and 2020, and concluded that no impairment had occurred as the recoverable amount, based on the fair value less cost of disposal using a discounted cash flow model incorporating significant unobservable inputs, exceeded the carrying amount of goodwill. The estimates regarding the expected future cash flows and discount rates are Level 3 fair value inputs based on various assumptions including existing contracts, future vessel redeployment rates, financial forecasts and industry trends. The Partnership has not previously recorded any impairment expense related to the carrying amount of goodwill for the shuttle tanker segment. The key assumptions used in the estimation of the recoverable amount are set out below. The values assigned to the key assumptions represent the Partnership's assessment of future trends in the relevant industries and have been based on historical data from both external and internal sources. 2021 2020 Discount rate 7.29% 6.73% Exit multiple 8.0 8.0 Discount rate The discount rate is a post-tax measure, with a possible debt leveraging of 70% for 2021 (2020 - 70%) estimated based on the observed leveraging within the industry and the long-term target leverage of the Partnership, at market interest rates of 4.2% for 2021 (2020 - 3.9%). Exit Multiple The cash flow projections include specific estimates for generally six years and a terminal value thereafter. The terminal value is estimated using an EBITDA multiple generally applied to the year-six EBITDA and discounted using the discount rates described above. The EBITDA multiple was determined based on an average of the EBITDA multiples used by the Partnership's industry peers and is therefore determined to be consistent with the assumptions that a market participant would make. The Partnership has identified that a reasonably possible change in these key assumptions could cause the carrying amount to exceed the recoverable amount. The following table shows the amount by which these two assumptions would need to change individually for the estimated recoverable amount to be equal to the carrying amount. 2021 2020 Discount rate 3.98% 3.23% Exit multiple (1.6) (1.7)

Certain of these claims have been assessed by the Partnership as having a remote possibility of any outflow from settlement and are therefore not included in the disclosures below. In addition to the claims described below, as at December 31, 2021, approximately $4.7 million has been accrued by the Partnership and its subsidiaries relating to other various legal claims. a) In August 2014, the Partnership acquired 100% of the outstanding shares of Logitel Offshore Holding AS (or Logitel ), a Norway-based company focused on high-end UMS. At the time of the transaction, affiliates of Logitel were parties to construction contracts for three UMS newbuildings ordered from the COSCO (Nantong) Shipyard (or COSCO ) in China. The Partnership took delivery of one of the UMS newbuildings, the Arendal Spirit UMS , in February 2015. In June 2016, the Partnership canceled the UMS construction contracts for the two remaining UMS newbuildings, the Stavanger Spirit and the Nantong Spirit . As a result of this cancellation, during 2016, the Partnership wrote-off $43.7 million of assets related to these newbuildings and reversed contingent liabilities of $14.5 million associated with the delivery of these assets. During December 2017, Logitel Offshore Rig II Pte Ltd., the single-purpose subsidiary relating to the Stavanger Spirit, received a notice of arbitration from COSCO to arbitrate all disputes arising from the cancellation of the construction contract of the Stavanger Spirit UMS and during March 2018, COSCO commenced arbitration against Logitel Offshore Rig II Pte Ltd. and Logitel Offshore Pte. Ltd. claiming $186.2 million plus interest, damages and costs. Pursuant to the Stavanger Spirit newbuilding contract and related agreements, COSCO only has recourse to the single-purpose subsidiary that was a party to the Stavanger Spirit newbuilding contract and its immediate parent company, Logitel Offshore Pte. Ltd., for damages incurred. Logitel Offshore Rig II Pte Ltd. and Logitel Offshore Pte. Ltd. are disputing this claim. The original estimate of the potential damages for the cancellation of the Stavanger Spirit newbuilding contract was based on the amount due for the final yard installment of approximately $170 million less the estimated fair value of the Stavanger Spirit . Given the unique design of the vessel as well as the lack of recent sale and purchase transactions for this type of asset in 2016, the value of this vessel, and thus ultimately the amount of potential damages that may result from the cancellation, is uncertain. The Partnership's original estimate of potential damages for the cancellation of the Nantong Spirit newbuilding contract was based upon estimates of a number of factors, including accumulated costs incurred by COSCO, sub-supplier contract cancellation costs, as well as how such costs are treated under the termination provisions in the contract. Pursuant to the Nantong Spirit newbuilding contract, COSCO only has recourse to the single-purpose subsidiary that was a party to the Nantong Spirit newbuilding contract. During June 2017, Logitel Offshore Rig III LLC, the single-purpose subsidiary relating to the Nantong Spirit , received a claim from COSCO for $51.9 million for the unpaid balance for work completed, cancellation costs and damages, and during the third quarter of 2017, COSCO commenced arbitration against Logitel Offshore Rig III LLC. Logitel Offshore Rig III LLC is disputing this claim. As at December 31, 2021, pursuant to the level of maturity in settlement discussions held with COSCO, the Partnership has released $49.3 million of accrued provisions relating to these claims. As at December 31, 2021, the Partnership's subsidiaries have accrued $8.3 million in the aggregate related to the above COSCO claims related to Logitel. b) During 2019, certain entities and individuals, which together claim to hold approximately 5,000,000 of the Partnership’s common units, filed complaints in the United States District Court for the Southern District of New York naming as defendants the Partnership, the general partner, current and former members of the board of directors of the general partner, certain senior management of the Partnership, Brookfield and Brookfield Asset Management Inc. In October 2019, a joint stipulation was filed by the plaintiffs to consolidate the separate complaints. The plaintiffs purported to assert claims on behalf of a class of holders of the Partnership’s common units in relation to Brookfield’s unsolicited non-binding proposal, made in May 2019, pursuant to which Brookfield would acquire all of the Partnership’s issued and outstanding common units that Brookfield did not already own in exchange for $1.05 in cash per common unit. On October 1, 2019, the Partnership entered into an agreement with Brookfield to acquire by merger all of the outstanding publicly held common units not already held by Brookfield in exchange for $1.55 in cash per common unit (or, as an alternative, other equity consideration) and on January 22, 2020, Brookfield completed the merger of all of the outstanding publicly held and listed common units representing the Partnership's limited partner interests held by parties other than Brookfield (see Note 22 for additional information). On January 28, 2020, the same plaintiffs filed an amended complaint in which the plaintiffs purport to allege further claims in respect of the merger process and the ultimate agreed consideration of $1.55 in cash per common unit or alternative equity consideration. The complaints allege breaches of the Partnership’s limited partnership agreement and, in the alternative, breaches of an implied covenant of good faith and fair dealing. The complaints seek damages in an unspecified amount and an award to the plaintiffs of their costs and expenses incurred in the action, including their attorneys’ fees. The Partnership believes that there is no merit to these claims. On October 29, 2020, one of the lead plaintiffs filed, unsolicited, a notice of voluntary dismissal, effectively withdrawing its particular claim. On March 25, 2021, the court awarded a dismissal against all parties, with the exception of the Partnership. The case isl now proceeding to trial. The Partnership intends to proceed with an application for summary judgment, which will not occur until the fourth quarter of 2022 at the earliest.

Disclosure Of Revenue From Contracts With Customers [Abstract]
Contracts in Progress	Contracts in Progress Contract Assets and Liabilities Certain customer contracts that the Partnership enters into will result in situations where the customer will pay consideration for performance to be provided in the following month or months. These receipts are a contract liability and are presented within accounts payable and other as deferred revenues until performance is provided. In other cases, the Partnership will provide performance in the month or months prior to it being entitled to invoice for such performance. This results in such receipts being reflected as a contract asset that is presented within other assets. In addition to these short-term timing differences between the timing of revenue recognition and when the entity’s right to consideration in exchange for goods or services is unconditional, the Partnership has long-term charter arrangements whereby it has received payments that are larger in the early periods of the arrangements and long-term charter arrangements whereby it will receive payments that are larger in the latter periods of the arrangements. The following table presents the contract assets and contract liabilities on the Partnership's consolidated statements of financial position associated with these long-term charter arrangements from contracts with customers: December 31, 2021 December 31, 2020 $ $ Contract assets Current 24,916 18,958 Non-current 37,597 48,288 62,513 67,246 Contract liabilities Current 55,617 91,392 Non-current 358 11,616 55,975 103,008 During the year ended December 31, 2021, the Partnership recognized revenue of $85.6 million, which was included in contract liabilities on December 31, 2020. Contract Costs In certain cases, the Partnership incurs pre-operational costs that relate directly to a specific customer contract and that generate or enhance resources of the Partnership to satisfy future performance obligations, and where such costs are expected to be recovered via the customer contract. These costs include costs incurred to mobilize an offshore asset to an oil field, pre-operational costs incurred to prepare for commencement of operations of an offshore asset or costs incurred to reposition a vessel to a location where a charterer will take delivery of the vessel. In certain cases, the Partnership will need to make judgments about whether costs relate directly to a specific customer contract and whether costs were factored into the pricing of a customer contract and thus expected to be recovered. Such deferred costs are amortized into direct operating costs over the duration of the customer contract. Amortization of such costs for the Partnership for the years ended December 31, 2021, 2020 and 2019 were $19.3 million, $21.4 million and $20.9 million, respectively. The balances of assets recognized from the costs to fulfill a contract with a customer classified as other assets, split between current and non-current portions, on the Partnership's consolidated statements of financial position, by main category, excluding balances in the Partnership’s equity-accounted investments, are as follows: December 31, 2021 December 31, 2020 $ $ Pre-operational costs 2,803 7,750 Offshore asset mobilization costs 8,978 21,509 Vessel repositioning costs 10,583 11,565 22,364 40,824 a) Revenues by type The Partnership’s primary source of revenues is chartering its vessels and offshore units to its customers. The Partnership utilizes five primary forms of contracts, consisting of FPSO contracts, CoAs, time-charter contracts, bareboat charter contracts and voyage charter contracts. All of the Partnership's revenues relate to services transferred over a period of time. During the year ended December 31, 2021, the Partnership also generated revenues from the operation of VOC systems on certain of the Partnership’s shuttle tankers, and from the management of two FPSO units (December 31, 2020 - three FPSO units and one FSO unit, December 31, 2019 - three FPSO units, one FSO unit and two shuttle tankers) on behalf of the disponent owners or charterers of these assets.

The financing liability accrued interest at a fixed rate of 5.5% until the related newbuilding vessels were delivered to the Partnership during the first quarter of 2021, after which they accrue interest at a variable rate of LIBOR plus 2.85%. Derivative Financial Instruments The Partnership’s activities expose it to a variety of financial risks, including liquidity risk, interest rate risk, foreign currency risk and credit risk. The Partnership selectively uses derivative financial instruments to manage certain of these risks. The aggregate amount of the Partnership's derivative financial instrument positions is as follows: December 31, 2021 December 31, 2020 Financial Asset Financial Liability Financial Asset Financial Liability $ $ $ $ Interest rate swaps — 23,470 — 203,597 Foreign currency forward contracts 325 758 6,497 — Total 325 24,228 6,497 203,597 Total current 325 23,688 6,497 189,647 Total non-current — 541 — 13,950 Interest Rate Risk The Partnership enters into interest rate swaps, which exchange a receipt of floating interest for a payment of fixed interest, to reduce the Partnership’s exposure to interest rate variability on its outstanding floating-rate debt. The Partnership has not designated, for accounting purposes, any of its interest rate swaps held during the years ended December 31, 2021, 2020 and 2019 as hedges of variable rate debt. Certain of the Partnership's interest rate swaps are secured by vessels. As at December 31, 2021, the Partnership and its consolidated subsidiaries were committed to the following interest rate swap agreements: Interest Notional Fair Value / Carrying Amount of Asset (Liability) (1) $ Weighted- Fixed Interest Rate (%) (2) U.S. Dollar-denominated interest rate swaps (3)(4)(5) LIBOR 152,903 (6,715) 0.55 2.6 % U.S. Dollar-denominated interest rate swaps (6)(7)(8) LIBOR 388,745 (16,755) 0.75 2.5 % 541,648 (23,470) (1) Excludes accrued interest of $1.8 million.

(3) Notional amount remains constant over the term of the swap, unless the swap is partially terminated. (4) Includes one interest rate swap, which as at December 31, 2021, had a total current notional amount of $100.0 million and a total fair value liability of $1.3 million. This interest rate swap is due to terminate in the third quarter of 2022. (5) Includes one interest rate swap, which as at December 31, 2021, had a total current notional amount of $52.9 million and a total fair value liability of $5.9 million.

(7) Includes one interest rate swap, which as at December 31, 2021, had a total current notional amount of $78.0 million and a total fair value liability of $11.2 million. This interest rate swap includes mandatory termination provisions which terminate this interest rate swap in the first quarter of 2022. (8) Includes three interest rate swaps, which as at December 31, 2021, had a total current notional amount of $285.3 million and a total fair value liability of $6.0 million. These interest rate swaps include mandatory termination provisions which terminate these interest rate swaps in the second quarter of 2022. During the year ended December 31, 2021, the effective portion of previously designated and qualifying cash flow hedges recorded in accumulated other comprehensive income during the term of the hedging relationship and reclassified to earnings and reported in interest expense was a gain of $0.8 million (December 31, 2020 - gain of $0.8 million, December 31, 2019 - gain of $0.7 million). As at December 31, 2021, the Partnership had multiple interest rate swaps and foreign currency forward contracts governed by certain master agreements. The fair value of these derivatives is presented on a gross basis in the Partnership’s consolidated statements of financial position. As at December 31, 2021, these derivatives had an aggregate fair value asset amount of $0.3 million and an aggregate fair value liability amount of $0.8 million (December 31, 2020 - an aggregate fair value asset amount of $6.5 million and an aggregate fair value liability amount of $147.5 million).

Other Information Regarding Derivative Financial Instruments Series D Detachable Warrants In June 2016, the Partnership issued 4,500,000 warrants with an exercise price of $4.55 per unit (the $4.55 Warrants ) and 2,250,000 warrants with an exercise price of $6.05 per unit (the $6.05 Warrants ) (collectively, the Warrants ) to a group of investors and subsidiaries of Teekay Corporation. In September 2017, the exercise price of the $6.05 Warrants was reduced to $4.55 per unit. As at December 31, 2019, the Warrants had a seven-year term and were exercisable any time after six months following their issuance date. The Warrants could be settled either in cash or common units at the Partnership’s option. The Warrants were classified as derivative financial instruments in the Partnership's consolidated statement of financial position with 6,750,000 Warrants outstanding at December 31, 2019. On January 22, 2020, Brookfield completed the Merger (see Note 22 for additional information) of all of the outstanding publicly held and listed common units representing the Partnership's limited partner interests held by parties other than Brookfield. As a result of this transaction, and the fact that the exercise price of each of the outstanding Warrants exceeded the cash consideration of $1.55 per common unit, each of the Warrants was automatically canceled and ceased to exist. No consideration was delivered in respect thereof. As at December 31, 2019, as a result of the pending Merger, the fair value measurement of the Warrants using Level 3 unobservable inputs was $nil. Brookfield Warrants In September 2017, the Partnership issued to Brookfield and Teekay Corporation 62.4 million and 3.1 million warrants, respectively (the Brookfield Warrants ), with each warrant exercisable for one common unit. As part of a separate transaction, Brookfield concurrently transferred 11.4 million Brookfield Warrants to Teekay Corporation. The Brookfield Warrants entitled the holders to acquire one common unit for each Brookfield Warrant for an exercise price of $0.01 per common unit, which was exercisable until September 25, 2024 if the Partnership's common unit volume-weighted average price was equal to or greater than $4.00 per common unit for 10 consecutive trading days. In July 2018, Brookfield, through an affiliate, exercised its option to acquire an additional 2% of ownership interests in the Partnership's general partner from an affiliate of Teekay Corporation in exchange for 1.0 million Brookfield Warrants. In May 2019, Brookfield acquired all of Teekay Corporation's remaining interests in the Partnership including 17.3 million common unit equivalent warrants. As at December 31, 2019, Brookfield held all of the 65.5 million Brookfield Warrants. On January 22, 2020, Brookfield completed the Merger (see Note 22 for additional information) of all of the outstanding publicly held and listed common units representing the Partnership's limited partner interests held by parties other than Brookfield. As a result of this transaction, and the fact that the exercise price of each of the outstanding Brookfield Warrant exceeded the cash consideration of $1.55 per common unit, each of the Brookfield Warrants was automatically canceled and ceased to exist. No consideration was delivered in respect thereof.

The term loans reduce over time with quarterly or semi-annual payments and have varying maturities through 2034. In February 2021, the Partnership refinanced an existing term loan relating to the financing of the Petrojarl I FPSO unit. The new facility provides for borrowings of $75.0 million, which reduces over time with monthly payments and matures in February 2024. The interest payments on the new facility are based on LIBOR plus a margin of 3.50% per annum. Public and Non-Public Bonds As at December 31, 2021, the Partnership had public bonds outstanding which totaled $725.1 million (December 31, 2020 - $726.8 million).

The exchanges included $415.2 million in aggregate principal amount of the 8.50% Senior Notes, $236.9 million in aggregate principal amount of loans relating to an unsecured revolving credit facility provided by Brookfield, which was due to mature in October 2024, $30.0 million in aggregate principal amount of loans relating to an unsecured revolving credit facility provided by Brookfield, which was due to mature in February 2022, and $17.2 million in aggregate principal amount of loans relating to an unsecured revolving credit facility provided by Brookfield, which was due to mature in July 2022, in each case for newly issued 11.50% Senior Secured PIK Notes due August 2026 in an equal aggregate principal amount. As at December 31, 2021, the Partnership has accrued a total of $27.7 million of PIK interest, increasing the principal amount of the 11.50% PIK Notes in an amount equal to the interest. Any outstanding principal balances are due on the maturity date. On July 2, 2018, the Partnership issued, in a U.S. private placement, a total of $700.0 million senior unsecured bonds due in July 2023. The interest payments on the bonds were fixed at a rate 8.50% (see Note 19 for additional information). Brookfield purchased $500.0 million of these bonds and as at the date of the Brookfield Exchanges, August 27, 2021, Brookfield held $411.3 million of these bonds (December 31, 2020 - $411.3 million). As part of the Brookfield Exchanges, Altera Infrastructure Holdings L.L.C. issued to Brookfield additional 11.50% PIK Notes in an aggregate principal amount equal to the $4.0 million then accrued and unpaid interest under the exchanged 8.50% Senior Notes. Consistent with the Partnership’s new accounting policy election in August 2021, these notes have been retrospectively reclassified from Borrowings (non-current) to Due to related parties (non-current) on the Partnership's consolidated statements of financial position. Please refer to Note 2i for additional information. As of August 27, 2021, the date of the Brookfield Exchanges, the Partnership had an undrawn balance of $nil (December 31, 2020 - $nil) relating to an unsecured revolving credit facility provided by Brookfield, which had previously provided for borrowings of up to $225.0 million and matured on October 31, 2024. The interest payments on the facility were based on LIBOR plus a margin of 5.00%. The facility provided the Partnership the option to defer interest payments of up to $25.0 million until maturity. As at August 27, 2021, the Partnership had deferred a total of $11.9 million of interest payments, which deferred interest was exchanged for the issuance to Brookfield as part of the Brookfield Exchanges of additional 11.50% PIK Notes with an aggregate principal amount of $11.9 million. The Partnership had previously determined that, as the interest rate under the revolving credit facility was deemed to be at below market terms, Brookfield was acting in its capacity as an equity owner and the Partnership recorded a $37.1 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's consolidated statements of changes in equity during the year ended December 31, 2020. As a result of the Brookfield Exchanges, the Partnership determined that the 11.50% PIK Notes were issued at fair value and therefore the then-remaining unamortized discount of $28.0 million was recorded as a loss through Gain (loss) on modification of financial liabilities, net on the Partnership’s consolidated statements of income (loss) during the year ended December 31, 2021. Prior to the Brookfield Exchanges, during the year ended December 31, 2021, the Partnership entered into an unsecured revolving credit facility provided by Brookfield, which had previously provided for borrowings of up to $30.0 million and as at the date of the Brookfield Exchanges, August 27, 2021, was fully drawn. The interest payments on the facility were based on LIBOR plus a margin of 5.00% and the facility matured in February 2022. Any outstanding principal balances were due on the maturity date. During the year ended December 31, 2021, the Partnership determined that the interest rate under the facility was deemed to be at below market terms and therefore, Brookfield was acting in its capacity as an equity owner. The Partnership recorded a $1.3 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's consolidated statements of changes in equity during the year ended December 31, 2021. As a result of the Brookfield Exchanges, the Partnership determined that the 11.50% PIK Notes were issued at fair value and therefore the then-remaining unamortized discount of $0.5 million was recorded as a loss through Gain (loss) on modification of financial liabilities, net on the Partnership’s consolidated statements of income (loss) during the year ended December 31, 2021. Prior to the Brookfield Exchanges, during the year ended December 31, 2021, a subsidiary of the Partnership entered into an unsecured revolving credit facility provided by Brookfield, which had previously provided for borrowings of up to $17.0 million and as at the date of the Brookfield Exchanges, August 27, 2021, was fully drawn. Borrowings under the facility bore interest solely in kind at a rate of 11.50% per annum. The facility had a maturity date of July 2022. Any outstanding principal balances were due on the maturity date. As part of the Brookfield Exchanges, Holdco issued to Brookfield additional 11.50% PIK Notes with an aggregate principal amount of $0.2 million, equal to the then accrued and unpaid interest under the term loan facility. b) On December 14, 2021, a wholly owned subsidiary of the Partnership, Altera Shuttle Tankers L.L.C., entered into an agreement with Brookfield to issue $70.0 million aggregate principal amount unsecured PIK notes (or the 12.50% PIK Notes ), which contemporaneously discharged the then-existing $70.0 million unsecured revolving credit facility which was fully drawn, accrued interest at a rate equal to LIBOR plus a margin of 5.00% and was due to mature in February 2022. Interest under the 12.50% Notes is payable in kind at a fixed rate of 12.50% and the facility matures in June 2026. The 12.50% PIK Notes are to be listed on The International Stock Exchange. Additional 12.50% PIK Notes may only be issued to satisfy the interest payable under the notes. As at December 31, 2021, the Partnership has accrued a total of $0.5 million of PIK interest, increasing the outstanding principal amount of the 12.50% PIK Notes in an amount equal to the interest. Any outstanding principal balances are due on the maturity date. During the year ended December 31, 2021, the Partnership determined that the interest rate under the $70.0 million revolving credit facility described above was deemed to be at below market terms and therefore, Brookfield was acting in its capacity as an equity owner. The Partnership recorded a $0.6 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's consolidated statements of changes in equity during the year ended December 31, 2021. As at December 31, 2021, the contractual maturities of the Partnership's borrowings due to related parties were as follows: Total 1 Year 2 Years 3 Years 4 Years 5 Years Thereafter (in millions of U.S. Dollars) Borrowings due to related parties: 11.50% Senior Secured PIK notes 727.0 — — — — 727.0 — 12.50% Unsecured PIK notes 70.5 — — — — 70.5 — Total borrowings due to related parties 797.5 — — — — 797.5 — As at December 31, 2021, the Partnership was in compliance with the covenant requirements of these facilities.

Disclosure Of Share Capital, Reserves And Other Equity Interest [Abstract]
Equity	Equity As at December 31, 2021, the Partnership's capital structure was comprised of three classes of partnership units; Class A common units, Class B common units and preferred limited partnership units, in addition to the general partnership interest. The Partnership may issue additional securities at any time and from time to time for such consideration and on such terms and conditions as the General Partner shall determine, without the approval of any Limited Partners. Limited Partners' Rights Significant rights of the Class A Common Unitholders include the following: • The Class A Common Unitholders are entitled to receive, to the extent permitted by law, such distributions as may from time to time be declared by the general partner’s board of directors. Upon any liquidation, dissolution or winding up of the Partnership’s affairs, whether voluntary or involuntary, the Class A Common Unitholders are entitled to receive distributions of the Partnership’s assets, after it has satisfied or made provision for its debts and other obligations and for payment to the holders any class or series of limited partner interests (including the Partnership’s preferred units) having preferential rights to receive distributions of Partnership assets. • No limited partner has any management power over the Partnership’s business and affairs; the general partner conducts, directs and manages the Partnership's activities. • The Class A Common Units have no voting rights except as required by the Marshall Islands Limited Partnership Act, but only to the extent that such voting rights under such Act may not be waived. • Class A Unitholders have certain pre-emptive rights, entitling them to purchase a portion of certain issuances of additional common units (or other securities that have rights and preferences that rank pari passu with the common units). • The Class A Common Units are subject to certain redemption provisions in connection with any Brookfield Sales Event (as defined in the Partnership’s partnership agreement). • No Class A Common Unitholder may sell, assign, convey, pledge, transfer or otherwise dispose of any Class A Common Units other than in connection with a Brookfield Sales Event (as defined in the Partnership's partnership agreement), and any sale, assignment, conveyance, pledge, transfer or other disposition of Class A Common Units in violation of the Partnership's partnership agreement, other than by operation of law (including intestacy), shall be null and void. Significant rights of the Class B Common Unitholders include the following: • Right to receive distributions of Available Cash (as defined in the Partnership’s partnership agreement) similar to those applicable to the Class A Common Unitholders. • No limited partner has any management power over the Partnership’s business and affairs; the general partner conducts, directs and manages the Partnership's activities. • The Class B Common Units are entitled to vote on various matters, as specified in the Partnership’s partnership agreement. • The general partner may be removed if such removal is approved by the Class B Common Unitholders holding at least 66.67% of the outstanding units voting as a single class, including units held by the general partner and its affiliates. On January 22, 2020, Brookfield completed its acquisition by merger (or the Merger ) of all of the outstanding publicly held and listed common units representing the Partnership's limited partner interests held by parties other than Brookfield (or unaffiliated unitholders ) pursuant to an agreement and plan of merger (or the Merger Agreement ) among the Partnership, the general partner and certain members of Brookfield. Under the terms of the Merger Agreement, (a) a newly formed subsidiary of Brookfield merged with and into the Partnership, with the Partnership surviving as a wholly owned subsidiary of Brookfield and the Partnership's general partner, and (b) common units held by unaffiliated unitholders were converted into the right to receive $1.55 in cash per common unit (or the cash consideration ), other than common units held by unaffiliated unitholders who, as an alternative to receiving the cash consideration, elected to forego the cash consideration and instead receive one of the Partnership's newly designated unlisted Class A Common Unit per common unit held immediately prior to the Merger (or the equity consideration ). The Class A Common Units are economically equivalent to the Class B Common Units held by Brookfield following the Merger, but have limited voting rights and limited transferability. At December 31, 2021, Brookfield held 100% of the Class B Common Units, representing 98.7% of the outstanding common units and 100% of the general partner interest. All of the Partnership's Class A Common Units, representing 1.3% of the Partnership’s outstanding common units, were held by entities other than Brookfield and its affiliates. At December 31, 2021, all of the Partnership’s outstanding 7.25% Series A Cumulative Redeemable Preferred Units (or the Series A Preferred Units ), 8.50% Series B Cumulative Redeemable Preferred Units (or the Series B Preferred Units ) and 8.875% Series E Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (or the Series E Preferred Units and, together with the Series A Preferred Units and the Series B Preferred Units, the Preferred Units ) were held by entities other than Brookfield and its affiliates. As a result of the Merger, the Partnership's common units that previously existed, were exchanged for either Class A Common Units or Class B Common Units. The net assets ascribed to the previously existing common units immediately preceding the Merger were allocated to the Class A Common Units or Class B Common Units based on their proportionate ownership percentages. As a result of the Merger , each of the Partnership's outstanding warrants (the Warrants ) were automatically canceled and ceased to exist. No consideration was delivered in respect thereof. Pursuant to the terms of the Merger Agreement, the Partnership's outstanding preferred units were unchanged and remain outstanding following the Merger. Incentive Distribution Rights As a result of the Merger, the general partner's incentive distribution rights, which granted the holder varying distributions based on the amount of quarterly cash distributions per common unit, were canceled and ceased to exist. Series A, B and E Preferred Units In April 2013, the Partnership issued 6.0 million Series A Preferred Units in a public offering with an aggregate redemption amount of $150.0 million, for net proceeds of $144.8 million. Pursuant to the partnership agreement, distributions on the Series A Preferred Units to preferred unitholders are cumulative from the date of original issue and are payable quarterly in arrears, when, as and if declared by the board of directors of the general partner. At any time on or after April 30, 2018, the Series A Preferred Units may be redeemed by the Partnership at a redemption price of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions to the date of redemption. These units are listed on the New York Stock Exchange under the symbol "ALIN PR A". In April 2015, the Partnership issued 5.0 million Series B Preferred Units in a public offering with an aggregate redemption amount of $125.0 million, for net proceeds of $120.8 million. Pursuant to the partnership agreement, distributions on the Series B Preferred Units to preferred unitholders are cumulative from the date of original issue and are payable quarterly in arrears, when, as and if declared by the board of directors of the general partner. At any time on or after April 20, 2020, the Series B Preferred Units may be redeemed by the Partnership at a redemption price of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions to the date of redemption. These units are listed on the New York Stock Exchange under the symbol "ALIN PR B". In January 2018, the Partnership issued 4.8 million Series E Preferred Units in a public offering for net proceeds of $116.0 million. Pursuant to the partnership agreement, distributions on the Series E Preferred Units to preferred unitholders are cumulative from the date of original issue, payable quarterly in arrears, when, as and if declared by the board of directors of the general partner. Distributions are payable on the Series E Preferred Units (i) from and including the original issue date to, but excluding, February 15, 2025 at a fixed rate equal to 8.875% per annum of the stated liquidation preference of $25.00 per unit and (ii) from and including February 15, 2025, at a floating rate equal to three-month LIBOR plus 6.407%. These units are listed on the New York Stock Exchange under the symbol "ALIN PR E". In September 2020, the Partnership announced that it intended to repurchase certain of its outstanding Series A, B and E Preferred Units. As at December 31, 2020, the Partnership had repurchased 123,467 of the Series A Preferred Units, 89,981 of the Series B Preferred Units and 96,977 of the Series E Preferred units, for a total cash payment of $6.2 million that resulted in a net gain on repurchase of $1.6 million, which was recorded in the Partnership's Consolidated Statement of Changes in Equity as an equity contribution to the Class A and Class B common unitholders, as well as the general partner. As at December 31, 2021, the Partnership had additionally repurchased 956 of the Series B Preferred Units at an average price of $21.98 per unit, thus completing the repurchase program. Net Income (Loss) Per Limited Partner Unit The general partner’s and common unitholders’ interests in net income (loss) are calculated as if all net income (loss) were distributed, regardless of whether those earnings would or could be distributed. The partnership agreement does not provide for the distribution of net income (loss); rather, it provides that, with respect to any quarter, the general partner may elect to distribute Available Cash, which is a contractually defined term that generally means all cash on hand at the end of each quarter less, among other things, the amount of cash reserves established by the general partner’s board of directors to provide for the proper conduct of the Partnership’s business, including, among other things, any accumulated distributions on, or redemptions of, the Series A, Series B and Series E Preferred Units. Unlike available cash, net income (loss) is affected by non-cash items such as depreciation and amortization, unrealized gain or loss on derivative instruments and unrealized foreign currency translation gain and loss. For all periods presented in these consolidated financial statements, no common unit equivalent warrants or restricted units were included in the computation of limited partners’ interest in net income (loss) per common unit - diluted, as their effect was anti-dilutive. The weighted average number of total common units were as follows for the periods indicated: Year Ended December 31, 2021 2020 2019 Weighted average number of total common units 411,148,991 411,148,991 410,727,035 Preferred Unit Distributions The distributions payable or paid on the preferred units for the year ended December 31, 2021 were $15.8 million (December 31, 2020 - $32.1 million; December 31, 2019 - $32.2 million), and the amount of cumulative preference dividends that has not been recognized for the year ended December 31, 2021 were $15.8 million (December 31, 2020 - $nil; December 31, 2019 - $nil). In July 2021, the Partnership suspended the payment of quarterly cash distributions on its outstanding Preferred Units, commencing with the distributions payable with respect to the period of May 15, 2021 to August 14, 2021. All distributions on the Preferred Units will continue to accrue and must be paid in full before distributions to Class A and Class B common unitholders can be made. No distributions on the Preferred Units will be permitted without noteholder consent while the newly issued 11.50% PIK Notes issued in the Brookfield Exchanges remain outstanding (see Note 21a).

In addition, the Libra Joint Venture entered into ten-year interest rate swap agreements, with an aggregate notional amount of $430.8 million as at December 31, 2021 (December 31, 2020 - $483.5 million), which amortize quarterly over the term of the agreements. These interest rate swap agreements exchange the receipt of LIBOR-based interest for the payment of a weighted average fixed rate of 2.52%. These interest rate swap agreements are not designated as qualifying cash flow hedging relationships for accounting purposes. Itajai Joint Venture The Partnership's investment in the Itajai Joint Venture (as defined below) includes its investments in the below entities: Name of Joint Venture State or Jurisdiction of Incorporation Proportion of Ownership Interest OOG-TKP FPSO GmbH Austria 50% OOG-TKP FPSO GmbH & Co KG Austria 50% OOG-TKP Oil Services Ltd.

Disclosure Of Revenue From Contracts With Customers [Abstract]
Revenues	Contracts in Progress Contract Assets and Liabilities Certain customer contracts that the Partnership enters into will result in situations where the customer will pay consideration for performance to be provided in the following month or months. These receipts are a contract liability and are presented within accounts payable and other as deferred revenues until performance is provided. In other cases, the Partnership will provide performance in the month or months prior to it being entitled to invoice for such performance. This results in such receipts being reflected as a contract asset that is presented within other assets. In addition to these short-term timing differences between the timing of revenue recognition and when the entity’s right to consideration in exchange for goods or services is unconditional, the Partnership has long-term charter arrangements whereby it has received payments that are larger in the early periods of the arrangements and long-term charter arrangements whereby it will receive payments that are larger in the latter periods of the arrangements. The following table presents the contract assets and contract liabilities on the Partnership's consolidated statements of financial position associated with these long-term charter arrangements from contracts with customers: December 31, 2021 December 31, 2020 $ $ Contract assets Current 24,916 18,958 Non-current 37,597 48,288 62,513 67,246 Contract liabilities Current 55,617 91,392 Non-current 358 11,616 55,975 103,008 During the year ended December 31, 2021, the Partnership recognized revenue of $85.6 million, which was included in contract liabilities on December 31, 2020. Contract Costs In certain cases, the Partnership incurs pre-operational costs that relate directly to a specific customer contract and that generate or enhance resources of the Partnership to satisfy future performance obligations, and where such costs are expected to be recovered via the customer contract. These costs include costs incurred to mobilize an offshore asset to an oil field, pre-operational costs incurred to prepare for commencement of operations of an offshore asset or costs incurred to reposition a vessel to a location where a charterer will take delivery of the vessel. In certain cases, the Partnership will need to make judgments about whether costs relate directly to a specific customer contract and whether costs were factored into the pricing of a customer contract and thus expected to be recovered. Such deferred costs are amortized into direct operating costs over the duration of the customer contract. Amortization of such costs for the Partnership for the years ended December 31, 2021, 2020 and 2019 were $19.3 million, $21.4 million and $20.9 million, respectively. The balances of assets recognized from the costs to fulfill a contract with a customer classified as other assets, split between current and non-current portions, on the Partnership's consolidated statements of financial position, by main category, excluding balances in the Partnership’s equity-accounted investments, are as follows: December 31, 2021 December 31, 2020 $ $ Pre-operational costs 2,803 7,750 Offshore asset mobilization costs 8,978 21,509 Vessel repositioning costs 10,583 11,565 22,364 40,824 a) Revenues by type The Partnership’s primary source of revenues is chartering its vessels and offshore units to its customers. The Partnership utilizes five primary forms of contracts, consisting of FPSO contracts, CoAs, time-charter contracts, bareboat charter contracts and voyage charter contracts. All of the Partnership's revenues relate to services transferred over a period of time. During the year ended December 31, 2021, the Partnership also generated revenues from the operation of VOC systems on certain of the Partnership’s shuttle tankers, and from the management of two FPSO units (December 31, 2020 - three FPSO units and one FSO unit, December 31, 2019 - three FPSO units, one FSO unit and two shuttle tankers) on behalf of the disponent owners or charterers of these assets.

Disclosure Of Entity's Operating Segments [Abstract]
Segment Information	Segment Information For the year ended December 31, 2021, the Partnership's operations were organized into five (December 31, 2020 - five, December 31, 2019 - six, including the Conventional segment) operating segments: FPSO, Shuttle Tanker, FSO, UMS and Towage. During the three months ended March 31, 2019, the Partnership redelivered its two in-chartered conventional tankers to their owners and ceased operations in the conventional tanker segment. These operating segments are regularly reviewed by the Partnership's CODM for the purpose of allocating resources to the segment and to assess its performance. The key measure used by the CODM in assessing performance and in making resource allocation decisions is Adjusted EBITDA, which is calculated as net income (loss) before interest expense, interest income, income tax expense, and depreciation and amortization, adjusted to exclude certain items whose timing or amount cannot be reasonably estimated in advance or that are not considered representative of core operating performance. Such adjustments include impairment expenses, gain (loss) on dispositions, net, unrealized gain (loss) on derivative instruments, foreign currency exchange gain (loss) and certain other income or expenses. Adjusted EBITDA also excludes: realized gain or loss on interest rate swaps, as management, in assessing the Partnership's performance, views these gains or losses as an element of interest expense; realized gain or loss on derivative instruments resulting from amendments or terminations of the underlying instruments; realized gain or loss on foreign currency forward contracts; and equity-accounted income (loss). Adjusted EBITDA also includes the Partnership's proportionate share of Adjusted EBITDA from its equity-accounted investments and excludes the non-controlling interests' proportionate share of Adjusted EBITDA. The Partnership does not have control over the operations of, nor does it have any legal claim to the revenues and expenses of its equity-accounted investments. Consequently, the cash flow generated by the Partnership’s equity-accounted investments may not be available for use by the Partnership in the period that such cash flows are generated. Adjusted EBITDA is also used by external users of the Partnership's consolidated financial statements, such as investors and the Partnership’s controlling unitholder. The following tables include the results for the Partnership’s reportable segments for the periods presented in these consolidated financial statements: Year Ended December 31, 2021 FPSO Segment Shuttle Tanker Segment FSO Segment UMS Segment Towage Segment Corporate/Eliminations (4) Total Revenues 489,878 513,495 75,405 895 80,134 (8,547) 1,151,260 Direct operating costs (279,677) (245,753) (30,292) (3,069) (67,632) (28,157) (654,580) General and administrative (1) (30,521) (30,180) (4,360) (5,252) (2,346) 31,889 (40,770) Adjusted EBITDA from equity-accounted investments (2) 95,880 — — — — — 95,880 Adjusted EBITDA attributable to non-controlling interests — 162 9 — — — 171 Adjusted EBITDA 275,560 237,724 40,762 (7,426) 10,156 (4,815) 551,961 Year Ended December 31, 2020 FPSO Segment Shuttle Tanker Segment FSO Segment UMS Segment Towage Segment Corporate/Eliminations (4) Total Revenues 483,297 542,691 113,867 1,828 45,991 (5,564) 1,182,110 Direct operating costs (266,299) (237,165) (45,448) (5,810) (45,636) (27,434) (627,792) General and administrative (1) (39,753) (17,942) (8,459) (3,564) (7,640) 32,998 (44,360) Realized loss on foreign currency forward contracts — (2,405) — — — 1,095 (1,310) Adjusted EBITDA from equity-accounted investments (2) 101,352 — — — — — 101,352 Adjusted EBITDA attributable to non-controlling interests — (10,988) 311 — — — (10,677) Adjusted EBITDA (3) 278,597 274,191 60,271 (7,546) (7,285) 1,095 599,323 Year Ended December 31, 2019 FPSO Segment Shuttle Tanker Segment FSO UMS Segment Towage Conventional Segment Corporate/Eliminations (4) Total Revenues 477,596 549,587 140,117 2,940 74,726 7,972 — 1,252,938 Direct operating costs (230,012) (230,946) (40,457) (1,292) (68,013) (9,304) (26,667) (606,691) General and administrative (1) (44,701) (22,267) (6,946) (6,100) (1,475) (104) 26,666 (54,927) Realized loss on foreign currency forward contracts — (2,574) — — — — (2,480) (5,054) Adjusted EBITDA from equity-accounted investments (2) 98,294 — — — — — — 98,294 Adjusted EBITDA attributable to non-controlling interests — (10,861) (500) — — — — (11,361) Adjusted EBITDA (3) 301,177 282,939 92,214 (4,452) 5,238 (1,436) (2,481) 673,199 (1) Includes direct general and administrative expenses and indirect general and administrative expenses (allocated to each segment based on estimated use of corporate resources).

Financial Risk Management

Financial Risk Management	12 Months Ended
	Dec. 31, 2021
Disclosure Of Financial Risk Management [Abstract]
Financial Risk Management	Financial Risk Management The Partnership recognizes that financial risk management is an integral part of a strong management practice. The Partnership is exposed to the following risks: capital risk, liquidity risk, market risk (i.e. interest rate risk, foreign currency risk and commodity risk) and credit risk. The following is a description of these risks and how they are managed: a. Capital risk management The capital structure of the Partnership consists of borrowings, offset by cash and equity. The Partnership's equity consists of Class A common units, Class B common units, preferred units, the general partners interest, accumulated other comprehensive income and non-controlling interests in subsidiaries. December 31, 2021 December 31, 2020 $ $ Borrowings 2,464,027 2,759,717 Obligations relating to leases 199,108 139,239 Due to related parties (1) 797,432 622,014 Less: Cash and cash equivalents 190,942 235,734 Restricted cash 64,815 133,389 Net debt 3,204,810 3,151,847 Total equity 100,678 244,899 Total equity and net debt 3,305,488 3,396,746 Net debt to capitalization ratio 97% 93% (1) Includes borrowings from related parties. Refer to Note 19. The Partnership manages its debt exposure by financing its operations with non-recourse borrowings in subsidiaries of the Partnership, ensuring a diversity of funding sources as well as managing its maturity profile. The Partnership also borrows in U.S. Dollars in order to mitigate its currency risk. As disclosed in Note 19, the Partnership has various credit facilities in place. In certain cases, the facilities have financial covenants which are generally in the form of debt service coverage ratios, vessel values to drawn principal balance ratios and minimum liquidity requirements. The Partnership does not have any market capitalization covenants attached to any of its borrowings, nor does it have any other externally imposed capital requirements. b. Liquidity risk management The Partnership maintains sufficient financial liquidity to be able to meet its ongoing operating requirements. The Partnership's primary liquidity needs for the next twelve months are to pay existing committed capital expenditures, to pay scheduled debt repayments, to pay debt service costs, to pay direct operating costs and dry-docking expenditures, to fund general working capital requirements, to settle claims and potential claims against the Partnership and to manage its working capital deficit. For further information on the Partnership's contractual obligations, including a maturity analysis, please refer to Notes 9, 11, 18 and 19. See Note 2b for the Partnership’s assessment of its ability to meet these obligations for at least the one-year period to December 31, 2022. c. Market risk Market risk is defined for these purposes as the risk that the fair value or future cash flows of a financial instrument held by the Partnership will fluctuate because of changes in market prices. Market risk includes the risk of changes in interest rates, foreign currency exchange rates and changes in market prices due to factors other than interest rates or foreign currency exchange rates, such as changes in commodity prices or credit spreads. Financial instruments held by the Partnership that are subject to market risk include borrowings and derivative instruments, such as interest rate swaps and foreign currency forward contracts. Interest rate risk management Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Partnership is exposed to the impact of interest rate changes, primarily through its floating-rate borrowings that require it to make interest payments based on LIBOR. Significant increases in interest rates could adversely affect operating margins, results of operations and the Partnership's ability to service its debt. The Partnership uses interest rate swaps to reduce its exposure to market risk from changes in interest rates. The principal objective of these contracts is to minimize the risks and costs associated with the Partnership's floating-rate debt. As at December 31, 2021, the Partnership had outstanding floating-rate debt balance of $1.6 billion (December 31, 2020 - $1.8 billion) and an outstanding notional balance of $0.5 billion (December 31, 2020 - $1.2 billion) of interest rate swaps. A 10 basis point decrease in the Partnership’s interest rates is expected to increase future cash flows by $1.0 million (December 31, 2020 - $0.7 million). The Partnership is exposed to credit loss in the event of non-performance by the counterparties to the interest rate swap agreements. In order to minimize counterparty risk, to the extent possible and practical, interest rate swaps are entered into with different counterparties to reduce concentration risk. For further information on the financial instruments held by the Partnership that are subject to interest rate risk, including borrowings and derivative instruments, please refer to Note 3, which includes the fair values of the interest rate risk sensitive financial instruments, and Notes 18 and 19, which include the expected cash flows from the interest rate risk sensitive financial instruments. Foreign currency risk management Foreign currency risk is the risk that the fair value or future cash flows of an exposure will fluctuate because of changes in foreign exchange rates. The net income impact to the Partnership of foreign currency risk associated with financial instruments is limited as its financial assets and liabilities are generally denominated in the Partnership's functional currency. However, the Partnership is exposed to foreign currency risk on the net assets of its foreign currency denominated operations. The Partnership enters into foreign currency forward contracts to mitigate the impact from movements in foreign exchange rates against the U.S. dollar.

The Partnership may use bunker fuel swap contracts as economic hedges to protect against changes in bunker fuel costs. As at December 31, 2021, the Partnership was not committed to any bunker fuel swap contracts. d. Credit risk Credit risk is the risk of loss due to the failure of a borrower or counterparty to fulfill its contractual obligations. The Partnership assesses the credit worthiness of each counterparty before entering into contracts and ensures that counterparties meet minimum credit quality requirements. The Partnership also evaluates and monitors counterparty credit risk for derivative financial instruments and endeavors to minimize counterparty credit risk through diversification. All of the Partnership’s derivative financial instruments involve either counterparties that are banks or other financial institutions. The Partnership does not have any significant credit risk exposure to any single counterparty. Based on no experience of past default of the Partnership's debtors and no expectations of future losses as a result of default, the Partnership has determined its credit risk to be low. For the purposes of credit risk, the Partnership has applied a definition to the term default as an assessment that a counterparty is unlikely to pay, as well as an amount outstanding from a counterparty which is 90 days past due. As at December 31, 2021, the Partnership recorded an ECL of $0.6 million (December 31, 2020 - $1.4 million).

Disclosure Of Events After Reporting Period [Abstract]
Subsequent Events	Subsequent Events a. In January 2022, a wholly owned subsidiary of the Partnership, Altera Infrastructure Holdings L.L.C., entered into a revolving credit facility provided by Brookfield. The borrowings available under the revolving credit facility are $32.0 million and mature in June 2022. The interest payments on the facility are based on a fixed rate of 10.00% per annum, with interest payable on March 31, 2022 and June 15, 2022. b. In January 2022, the Partnership agreed with Enauta to extend the Petrojarl I contract by one year, from May 2023 to May 2024, with an option to extend for an additional year through May 2025. c. In February 2022, the Partnership amended an existing term loan relating to the financing of the Arendal Spirit UMS unit. As at December 31, 2021, this term loan had an outstanding balance of $25.7 million and matured in February 2022. Following the amendment, this term loan had an outstanding balance of $8.5 million and matures in February 2023. The interest payments on the amended facility are based on LIBOR plus a margin of 2.0% per annum. d. In February 2022, the Partnership signed a FEED agreement with Equinor for redeployment of the Petrojarl Knarr FPSO unit on the Rosebank field. e. In February 2022, the Partnership signed an agreement with Energean Isreal Ltd. to redeploy the Arendal Spirit UMS on a 100 day firm contract with extension options. f. In February 2022, the Partnership entered into an agreement to sell the Petrojarl Varg FPSO unit to an energy company for re-use as a production facility as part of a new field development opportunity. The Partnership expects the sale to complete in March 2022. g. Following Russia’s invasion of Ukraine in February 2022, the U.S., several European Union nations, and other countries have announced sanctions against Russia. While it is difficult to anticipate the potential for any indirect impact the sanctions announced to date may have on the Partnership's business and the Partnership, any further sanctions imposed or actions taken by the U.S., EU nations or other countries, and any retaliatory measures by Russia in response, such as restrictions on oil shipments from Russia, could lead to increased volatility in global oil demand which, could have a material adverse impact on the Partnership's business, results of operations and financial condition.

Disclosure Of Significant Accounting Policies [Abstract]
Basis of presentation	Basis of presentation These consolidated financial statements of the Partnership have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (or IFRS ) and using the accounting policies described below. The consolidated financial statements have been prepared under the assumption that the Partnership operates on a going concern basis and have been presented in U.S. dollars rounded to the nearest thousand unless otherwise indicated. In the opinion of management of the Partnership’s general partner, Altera Infrastructure GP L.L.C. (or the general partner ), these consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary to present fairly, in all material respects, the Partnership’s consolidated financial position, results of operations, changes in total equity and cash flows as at dates and for the periods presented. These consolidated financial statements were approved by management and authorized for issue on March 9, 2022.
Going concern	Going concern As at December 31, 2021, the Partnership had a working capital deficit of $276.4 million primarily relating to the scheduled maturities and repayments of $407.3 million of outstanding borrowings and the settlement of $34.7 million of other financial liabilities, primarily interest rate swaps, during the 12 months ending December 31, 2022, which amounts were classified as current liabilities as at December 31, 2021. The Partnership also anticipates making payments related to commitments to fund the vessel under construction through 2022 of $74.0 million; however, the Partnership has secured long-term financing related to the vessel. The working capital deficit of $276.4 million as at December 31, 2021 has increased from $230.5 million as at December 31, 2020. The increase in the working capital deficit was primarily due to a $95.2 million decrease in accounts and other receivable, net, an $84.1 million decrease in financial assets, a $44.8 million decrease in cash and cash equivalents, and a $45.2 million increase in borrowings. This was partially offset by a $164.3 million decrease in other financial liabilities, and a $37.0 million decrease in accounts payable and other. During the year ended December 31, 2021, the Partnership completed various measures to improve its debt maturity profile and enhance its liquidity and financial flexibility, including but not limited to exchanging $769.3 million of Brookfield debt with 2022 to 2024 maturities into debt with interest paid in kind and with a 2026 maturity, discontinuing distributions on the Series A, Series B and Series E Preferred Units, issuing $180.0 million of new 2025 bonds in the shuttle tanker segment and refinancing the Petrojarl I FPSO unit. See Notes 19, 21a and b, and 22 for additional information. While these measures improved the Partnership's liquidity position, the Partnership continues to explore its liquidity management opportunities and seek to improve and extend its debt profile. In addition to the successfully completed initiatives during 2021, it is still critical that the Partnership will need to obtain additional sources of financing, in addition to amounts generated from operations, to meet its obligations and commitments and minimum liquidity requirements under its financial covenants. These requirements include but are not limited to maintaining a minimum liquidity in an amount equal to the greater of $75 million and 5% of total debt as well as maintaining within the Partnership's wholly-owned subsidiary, Altera Shuttle Tankers L.L.C., a minimum liquidity in an amount equal to the greater of $35 million and 5% of total debt and a net debt to total capitalization ratio of no greater than 75%. Additional potential sources of financing that the Partnership is actively pursuing, during the one-year period to December 31, 2022, include entering into new debt facilities, borrowing additional amounts under existing facilities, the refinancing, extension or other amendments, including amendment of financial covenants, of certain borrowings and interest rate swaps, selling certain assets, seeking joint venture partners for the Partnership's business interests, enter into sale-leaseback agreements, increasing equity, and other potential liability management transactions. Additional potential sources of amounts generated from operations include the extensions and redeployments of existing assets, higher utilization of the operating fleet, increased rates for vessels operating in the spot market, increased oil price-based tariffs from certain FPSOs and working capital optimizations. The Partnership is actively pursuing or may pursue the financing initiatives described above, which it considers probable of completion based on the Partnership’s history of being able to raise and refinance borrowings for similar types of vessels and based on the Partnership's assessment of current conditions and estimated future conditions. The Partnership is in various stages of progression on these matters. See Note 31a for additional information.
Basis of consolidation	Basis of consolidationThe consolidated financial statements include the accounts of the Partnership and its consolidated subsidiaries, which are the entities over which the Partnership has control. An investor controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Non-controlling interests in the equity of the Partnership’s subsidiaries held by others are shown separately in equity in the consolidated statements of financial position. All intercompany balances, transactions, revenues and expenses are eliminated in full in these consolidated financial statements.
Interests in other entities	Interests in other entities (i) Subsidiaries Subsidiaries are consolidated from the date of acquisition, being the date on which the Partnership obtained control, and continue to be consolidated until the date when control is lost. Non-controlling interests may be initially measured either at fair value or at the non-controlling interests’ proportionate share of the fair value of the acquiree’s identifiable net assets. The choice of measurement basis is made on an acquisition by acquisition basis. Subsequent to acquisition, the carrying amount of non-controlling interests is the amount of those interests at initial recognition plus the non-controlling interests’ share of subsequent changes in the Partnership's capital in addition to changes in ownership interests. Total comprehensive income (loss) is attributed to non-controlling interests, even if this results in the non-controlling interests having a deficit balance.

For non-wholly owned subsidiaries, the Partnership is exposed to variable returns from its involvement with the investee and has substantive decision making authority to affect the returns of its investment, as well as the power to direct the activities of the entities that can significantly impact the economic performance of the entity. (ii) Joint ventures Joint ventures are joint arrangements whereby the parties that have joint control of the arrangement have rights to the net assets of the joint arrangement. Joint control is the contractually agreed sharing of control over an arrangement, which exists when decisions about the relevant activities require unanimous consent of the parties sharing control. The Partnership accounts for joint ventures using the equity method of accounting within equity-accounted investments in the consolidated statements of financial position. Interests in joint ventures accounted for using the equity method are initially recognized at cost. Subsequent to initial recognition, the carrying value of the Partnership’s interest in a joint venture is adjusted for the Partnership’s share of comprehensive income and distributions of the investee. Profit and losses resulting from transactions with a joint venture are recognized in the consolidated financial statements based on the interests of unrelated investors in the investee. The carrying value of joint ventures is assessed for impairment at each reporting date. Impairment losses on equity-accounted investments may be subsequently reversed in net income. Further information on the impairment of long-lived assets is available in Note 2(l).

Foreign currency translation	Foreign currency translationThe U.S. dollar is the functional and presentation currency of the Partnership. The Partnership’s vessels operate in international shipping markets in which substantially all income and expenses are settled in U.S. dollars. In addition, the Partnership's most significant assets, its vessels and equipment, are bought and sold in U.S. dollars and the Partnership's most significant liabilities, its commercial bank borrowings, are denominated in U.S. dollars. Foreign currency denominated monetary assets and liabilities are translated using the rate of exchange prevailing at the reporting date and non-monetary assets and liabilities are measured at historic cost and are translated at the rate of exchange at the transaction date. Foreign currency denominated revenues and expenses are measured at average rates during the period. Gains or losses on translation of these items are included in foreign currency exchange gain (loss) in the consolidated statements of income (loss).
Cash and cash equivalents	Cash and cash equivalentsCash and cash equivalents include cash on hand, non-restricted deposits and short-term investments with original maturities of three months or less.
Accounts and other receivable, net	Accounts and other receivable, netAccounts and other receivable, net includes trade receivables and other unbilled receivables. Accounts and other receivable, net, except for trade receivables, are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less any allowance for expected credit losses. Trade receivables are recognized initially at their transaction price.
Inventory	Inventory Inventories are the materials or supplies consumed in the rendering of services. Inventory is valued at the lower of cost and net realizable value. Cost is determined using specific identification where possible and practicable or using the first-in, first-out method. Costs include direct and indirect expenditures incurred in bringing the inventory to its existing condition and location. Net realizable value represents the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale. The following table presents the details of the Partnership's inventory as at December 31, 2021 and 2020: December 31, 2021 December 31, 2020 $ $ Fuel oil 23,203 13,528 Materials and consumables 3,398 2,780 Total inventory 26,601 16,308
Related party transactions	Related party transactions In the normal course of operations, the Partnership enters into various transactions with related parties, which have been measured at their fair value, which generally is the agreed upon exchange value and are recognized in the consolidated financial statements. Related party transactions are further described in Note 21. Related Party Borrowings Reclassification The accounting policy elected historically by the Partnership has reflected its long-term debt within two line items, Borrowings and Due to related parties. Borrowings has included publicly listed debt held by third parties and by Brookfield. The related party component of publicly listed Borrowings has been historically disclosed in the notes to the financial statements. On August 27, 2021, the Partnership completed a refinancing with Brookfield (or the Brookfield Exchanges ) (see Note 21a for additional information) and voluntarily revised the Partnership's accounting policy to classify all debt held by Brookfield, regardless of the nature of the instrument as Due to related parties. The Partnership believes it is more relevant to show all related party debt on the same financial statement line item. The Partnership has reflected this change retrospectively by restating its comparative consolidated statement of financial position. Following the change, debt will continue to be included in two line items, Borrowings, which will include only debt held by third-party counterparties and Due to related parties, which will include all debt where Brookfield or other affiliates are the ultimate counterparty, regardless of whether a debt instrument is publicly listed. Additionally, all accrued interest on related party debt will be reflected within the Due to related parties line item rather than within Accounts payable and other, as previously reported. The following tables provides a reconciliation of the resulting reclassifications directly related to the change in accounting policy discussed above to the Partnership's consolidated statements of financial position: As at As at December 31, 2020 December 31, 2020 As Previously Reported Reclassifications Restated $ $ $ Accounts payable and other 302,414 (16,119) 286,295 Due to related parties 7 16,119 16,126 Total current liabilities 302,421 — 302,421 Borrowings 2,808,898 (411,260) 2,397,638 Due to related parties 194,628 411,260 605,888 Total non-current liabilities 3,003,526 — 3,003,526 Total liabilities 3,305,947 — 3,305,947 As at As at December 31, 2019 January 1, 2020 As Previously Reported Reclassifications Restated $ $ $ Accounts payable and other 272,618 (16,504) 256,114 Due to related parties 21,306 16,504 37,810 Total current liabilities 293,924 — 293,924 Borrowings 2,831,274 (423,625) 2,407,649 Due to related parties — 423,625 423,625 Total non-current liabilities 2,831,274 — 2,831,274 Total liabilities 3,125,198 — 3,125,198
Vessels and equipment	Vessels and equipment Vessels and equipment are measured at cost less accumulated depreciation and accumulated impairment losses, if any. Cost includes expenditures that are directly attributable to the acquisition of the asset including the cost of materials and direct labor, any other costs directly attributable to bringing the assets to a working condition for their intended use, and the cost of dismantling and removing the items and restoring the site on which they are located. All pre-delivery costs incurred during the construction of vessels and equipment, including interest, supervision and technical costs, are capitalized. The acquisition cost and all costs incurred to restore used vessels and equipment purchased by the Partnership to the standard required to service the Partnership’s customers are capitalized. Depreciation of an asset commences when it is available for use. Vessels and equipment are depreciated for each component of the asset classes as follows: Component Estimated Useful Life Dry docks and Overhauls 2.5 - 5 years Capital Modifications (1) 3 - 20 years Vessels and Equipment (2) 9 - 35 years (1) Includes field and contract specific equipment for the Partnership's FPSO units and FSO units, capital upgrades for the Partnership's shuttle tankers and mid-life refurbishments for the Partnership's UMS. (2) Certain of the Partnership's FPSO units and FSO units have undergone conversions or capital upgrades prior to commencing operations under their current contracts. The estimated useful lives of such vessels is generally substantially lower than that of a comparable newbuilding vessel. For a newbuilding vessel, the Partnership uses an estimated useful life of 20 to 25 years for its FPSO units, 20 years for its shuttle tankers, 35 years for its UMS and 25 years for its towage and offshore installation (or Towage ) vessels. The estimated useful life of the Partnership's FSO units are generally the contract term for the unit, inclusive of extension options. Depreciation on vessels and equipment is calculated on a straight-line basis so as to write-off the net cost of each asset over its expected useful life to its estimated residual value. Residual value of the vessel hull is estimated as the lightweight tonnage of each vessel multiplied by recycling value per ton. The estimated useful lives, residual values and depreciation methods are reviewed annually, with the effect of any changes recognized on a prospective basis. Vessel capital modifications include the addition of new equipment or can encompass various modifications to the vessel which are aimed at improving or increasing the operational efficiency and functionality of the asset. This type of expenditure is amortized over the estimated useful life of the modification. Expenditures covering recurring routine repairs or maintenance are expensed as incurred. Generally, the Partnership dry docks each shuttle tanker or towage vessel every two and a half to five years, depending on the nature of work and external requirements. The vessels are required to undergo planned dry docking for replacement of certain components, major repairs and major maintenance of other components, which cannot be carried out while the vessels are operating. The Partnership capitalizes a portion of the costs incurred during dry docking and amortizes those costs on a straight-line basis from the completion of a dry docking over the estimated useful life of the dry dock, which is generally until the commencement of the subsequent dry dock. Included in capitalized dry docking are costs incurred as part of the dry docking to meet regulatory requirements, or expenditures that either add economic life to the vessel, increase the vessel’s earning capacity or improve the vessel’s operating efficiency. A portion of the cost of acquiring a new vessel is allocated to the components expected to be replaced or refurbished at the next dry-docking. The Partnership expenses costs related to routine repairs and maintenance performed during dry docking that do not improve operating efficiency or extend the useful lives of the assets. Advances on newbuilding contracts consists of prepayments related to newbuilding contracts for vessels and equipment not yet delivered to the Partnership and include the share of borrowing costs that are directly attributable to the acquisition of the underlying vessel. When a vessel is delivered, the prepaid amount is reallocated to Vessels and equipment.
Right-of-use assets and lease obligations	Right-of-use assets and lease obligations The Partnership assesses whether a contract is, or contains, a lease at inception of the contract. A right-of-use asset and corresponding lease liability is recognized at the lease commencement date for contracts that are, or contain, a lease component, except for short-term leases and leases of low value. Agreements to charter in vessels and to lease land and buildings for which the Partnership substantially has the right to control the asset for a period of time in exchange for consideration are recognized in the consolidated statements of financial position as right-of-use assets within Other assets and are initially measured at cost, which comprises the initial amount of the lease liabilities adjusted for any lease payments made at or before the commencement date. Subsequently, the right-of-use assets are measured at cost less accumulated depreciation and impairment losses, if any. The right-of-use assets are depreciated on a straight-line basis over the lesser of the lease term or remaining life of the underlying asset, depending on the lease terms. The Partnership charters in vessels from other vessel owners on time-charter contracts, whereby the vessel owner provides use of the vessel to the Partnership, as well as operates the vessel for the Partnership. A time-charter contract is typically for a fixed period of time, although in certain cases the Partnership may have the option to extend the charter. The Partnership will typically pay the owner a daily hire rate that is fixed over the duration of the charter. The Partnership is generally not required to pay the daily hire rate during periods the vessel is not able to operate. The Partnership has determined that all of its time-charter-in contracts contain both a lease component (lease of the vessel) and a non-lease component (operation of the vessel). The Partnership has allocated the contract consideration between the lease component and non-lease component on a relative standalone selling price basis. Given that there are no observable standalone selling prices for either of these two components, judgment is required in determining the standalone selling price of each component. The standalone selling price of the non-lease component has been determined using a cost-plus approach, whereby the Partnership estimates the cost to operate the vessel using cost benchmarking studies prepared by a third party, when available, or internal estimates when not available, plus a profit margin. The standalone selling price of the lease component has been determined using an adjusted market approach, whereby the Partnership calculates a rate excluding the operating component based on a market time-charter rate from published broker estimates, when available, or internal estimates when not available. The discount rate of the lease is determined using the Partnership’s incremental borrowing rate, which is based on the fixed interest rate the Partnership could obtain when entering into a secured loan facility of similar term. The Partnership has elected to recognize the lease payments of short-term leases in profit or loss on a straight-line basis over the lease term and variable lease payments not dependent on a rate or index in the period in which the obligation for those payments is incurred, which is consistent with the recognition of payment for the non-lease component. Short-term leases are leases with an original term of one year or less, excluding those leases with an option to extend the lease for greater than one year or an option to purchase the underlying asset, that the lessee is reasonably certain to exercise. The corresponding lease obligation is recognized as a liability in the consolidated statements of financial position under Accounts payable and other and initially measured at the present value of the outstanding lease payments at the commencement date. The Partnership recognizes the lease payments for leases of low value as an operating expense on a straight-line basis over the term of the lease.
Asset impairment	Asset impairment At each reporting date the Partnership assesses whether there is any indication that assets or cash generating units, relating specifically to its vessels and equipment and right-of use-assets, are impaired. This assessment includes a review of internal and external factors which includes, but is not limited to, changes in the technological, political, economic or legal environments in which the Partnership operates, structural changes in the industry, changes in the level of demand, physical damage and obsolescence due to technological changes. The Partnership has determined that, for impairment purposes, each individual vessel, except for the Partnership's contract of affreightment (or CoA ) vessels, is a cash generating unit. This is due to the fact that the cash inflows from an individual vessel operating in the CoA fleet are not largely independent of the cash inflows from other vessels operating in the CoA fleet, i.e., the individual vessels are not the smallest identifiable group and therefore it is concluded that the CoA fleet is a single cash generating unit. An impairment is recognized if the recoverable amount, determined as the higher of the estimated fair value less costs of disposal or the value in use, is less than the carrying value of the asset or cash generating unit. In cases where an active second-hand sale and purchase market does not exist, the Partnership uses a discounted cash flow approach to estimate the fair value of its vessel and equipment. In cases where an active second-hand sale and purchase market exists, an appraised value is used to estimate the fair value of the vessel and equipment. An appraised value is generally the amount the Partnership would expect to receive if it were to sell the vessel. Such appraisal is normally completed by the Partnership. The value in use is the present value of the future cash flows that the Partnership expects to derive from the asset or cash generating unit. The projections of future cash flows take into account the relevant operating plans and management’s best estimate of the most probable set of conditions anticipated to prevail.
Goodwill	Goodwill Goodwill represents the excess of the price paid for the acquisition of a business over the fair value of the net tangible and intangible assets and liabilities acquired. Goodwill is allocated to the cash generating unit or units to which it relates. The Partnership identifies cash generating units as identifiable groups of assets whose cash inflows largely independent of the cash inflows from other assets or groups of assets. The Partnership has identified the shuttle tanker segment as the group of cash generating units to which the Partnership's goodwill relates. Goodwill is evaluated for impairment on an annual basis or more frequently if an event occurs or circumstances change that would indicate that the recoverable amount of a reporting unit was below its carrying value. Impairment is determined for goodwill by assessing if the carrying value of a cash generating unit, including the allocated goodwill, exceeds its recoverable amount determined as the greater of the estimated fair value less costs of disposal or the value in use. Impairment losses recognized in respect of a cash generating unit are first allocated to the carrying value of goodwill and any excess is allocated to the carrying amount of assets in the cash generating unit. Any goodwill impairment is charged to Impairment expense, net on the consolidated statements of income (loss) in the period in which the impairment is identified. Impairment losses on goodwill are not subsequently reversed.
Revenues	Revenues Each vessel charter may, depending on its terms, contain a lease component, a non-lease component or both. Revenues that are fixed on or prior to the commencement of the contract are recognized by the Partnership on a straight-line basis daily over the term of the contract. The Partnership’s primary source of revenues is chartering its vessels and offshore units to its customers. The Partnership utilizes five primary forms of contracts, consisting of FPSO contracts, CoA, time-charter contracts, bareboat charter contracts and voyage charter contracts. A highly probable criterion is required to be met with regards to recognizing revenue arising from variable consideration resulting from contract modifications and claims. For variable consideration, revenue is only recognized to the extent that it is highly probable that a significant reversal in the amount of revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. (i) FPSO Contracts Pursuant to an FPSO contract, the Partnership charters an FPSO unit to a customer for a fixed period of time, generally more than one year. The obligations within an FPSO contract, which include the lease of the FPSO unit to the charterer as well as the operation of the FPSO unit, are satisfied as services are rendered over the duration of such contract, as measured using the time that has elapsed from commencement of performance. Fees relating to the lease and operation of the FPSO (or hire) are typically invoiced monthly in arrears, based on a fixed daily hire amount. In certain FPSO contracts, the Partnership is entitled to a lump sum amount due upon commencement of the contract and may also be entitled to termination fees if the contract is canceled early. While the fixed daily hire amount may be the same over the term of the FPSO contract, in certain cases, the daily hire amount declines over the duration of the FPSO contract. As a result of the Partnership accounting for compensation from such charters on a straight-line basis over the duration of the charter, FPSO contracts where revenues are recognized before the Partnership is entitled to such amounts under the FPSO contracts will result in the Partnership recognizing a contract asset and FPSO contracts where revenues are recognized after the Partnership is entitled to such amounts under the FPSO contracts will result in the Partnership recognizing a contract liability. Some FPSO contracts include variable consideration components in the form of expense adjustments or reimbursements, incentive compensation and penalties. For example, some FPSO contracts contain provisions that allow the Partnership to be compensated for increases in the Partnership's costs to operate the unit during the term of the contract. Such provisions may be in the form of annual hire rate adjustments for changes in inflation indices or foreign currency rates, or in the form of cost reimbursements for vessel operating expenditures incurred. The Partnership may also earn additional compensation from periodic production tariffs, which are based on the volume of oil produced, the price of oil, as well as other monthly or annual operational performance measures. During periods in which production on the FPSO unit is interrupted, penalties may be imposed. Variable consideration under the Partnership’s contracts is typically recognized as incurred as either such revenues are allocated and accounted for under lease accounting requirements or, alternatively, when such consideration is allocated to the distinct period in which such variable consideration was earned. The Partnership does not engage in any specific activities to minimize residual value risk. Given the uncertainty involved in oil field production estimates and the resulting impact on oil field life, FPSO contracts typically will include extension options or options to terminate early. The Partnership has allocated the contract consideration between the lease component and non-lease component on a relative standalone selling price basis. Given that there are no observable standalone selling prices for either of these two components, judgment is required in determining the standalone selling price of each component. The standalone selling price of the non-lease component has been determined using a cost-plus approach, whereby the Partnership estimates the cost to operate the unit using internal estimates, plus a profit margin. The standalone selling price of the lease component has been determined using an adjusted market approach, whereby the Partnership calculates a rate excluding the operating component based on a market rate from published broker estimates, when available, or internal estimates when not available. (ii) CoAs Voyages performed pursuant to a CoA for the Partnership’s shuttle tankers are priced based on the pre-agreed terms in the CoA. The obligations within a voyage performed pursuant to a CoA, which the Partnership believes will typically include the lease of the vessel to the charterer as well as the operation of the vessel, are satisfied as services are rendered over the duration of the voyage, as measured using the time that has elapsed from commencement of performance. In addition, any expenses that are unique to a particular voyage, including any bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions, are the responsibility of the vessel owner. Consideration for such voyages consists of a fixed daily hire rate for the duration of the voyage, the reimbursement of costs incurred from fuel consumed during the voyage, as well as a fixed lump sum intended to compensate for time necessary for the vessel to return to the field following completion of the voyage. While such consideration is generally fixed, certain sources of variability exist, including variability in the duration of the voyage and the actual quantity of fuel consumed during the voyage. Payment for the voyage is not due until the voyage is completed. The duration of a single voyage will typically be less than two weeks and, as a result, the Partnership has applied the practical expedient in IFRS 15.121(a), which permits an entity, with a contract that has an original expected duration of one year or less, to not disclose the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied as of the end of the period. The Partnership does not engage in any specific activities to minimize residual value risk due to the short-term nature of the contracts. The Partnership has allocated the contract consideration between the lease component and non-lease component on a relative standalone selling price basis. Given that there are no observable standalone selling prices for either of these two components, judgment is required in determining the standalone selling price of each component. The standalone selling price of the non-lease component has been determined using a cost-plus approach, whereby the Partnership estimates the cost to operate the vessel using internal estimates, plus a profit margin. The standalone selling price of the lease component has been determined using an adjusted market approach, whereby the Partnership calculates a rate excluding the operating component based on a market rate from published broker estimates, when available, or internal estimates when not available. (iii) Time Charter Contracts Pursuant to a time charter contract, the Partnership charters a vessel or FSO unit to a customer for a fixed period of time, generally one year or more. The obligations under a time-charter contract, which includes the lease of the vessel to the charterer as well as the operation of the vessel, are satisfied as services are rendered over the duration of such contract, as measured using the time that has elapsed from commencement. In addition, any expenses that are unique to a particular voyage, including any bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions, are the responsibility of the customer, as long as the vessel is not off-hire. Hire is typically invoiced monthly in advance for time-charter contracts, based on a fixed daily hire amount. In certain long-term time-charters, the fixed daily hire amount will increase on an annual basis by a fixed amount to offset expected increases in operating costs. Therefore, the Partnership has applied the practical expedient in IFRS 15.B16, which permits an entity to recognize revenue based on the amount it has a right to invoice. As a result of the Partnership accounting for compensation from such charters on a straight-line basis over the duration of the charter, such fixed increases in rate will result in revenues being accrued in the first portion of the charter and such amount drawn down in the last portion of the charter. Sometimes charters include variable consideration components in the form of expense adjustments or reimbursements, incentive compensation and penalties. For example, certain time charters contain provisions that allow the Partnership to be compensated for increases in the Partnership's costs during the term of the charter. Such provisions may be in the form of annual hire rate adjustments for changes in inflation indices or in the form of cost reimbursements for vessel operating expenditures or dry-docking expenditures. During periods in which the vessels are off-hire or minimum speed and performance metrics are not met, penalties may be imposed. Variable consideration under the Partnership’s contracts is typically recognized as incurred as either such revenues are allocated and accounted for under lease accounting requirements or, alternatively, as such consideration is allocated to the distinct period in which such variable consideration was earned. The Partnership does not engage in any specific activities to minimize residual value risk. The Partnership has allocated the contract consideration between the lease component and non-lease component on a relative standalone selling price basis. Given that there are no observable standalone selling prices for either of these two components, judgment is required in determining the standalone selling price of each component. The standalone selling price of the non-lease component has been determined using a cost-plus approach, whereby the Partnership estimates the cost to operate the vessel using internal estimates, plus a profit margin. The standalone selling price of the lease component has been determined using an adjusted market approach, whereby the Partnership calculates a rate excluding the operating component based on a market rate from published broker estimates, when available, or internal estimates when not available. (iv) Bareboat Charter Contracts Pursuant to a bareboat charter contract, the Partnership charters a vessel or FSO unit to a customer for a fixed period of time, generally one year or more, at rates that are generally fixed. The customer is responsible for operation and maintenance of the vessel with their own crew as well as any expenses that are unique to a particular voyage, including any bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. If the vessel goes off-hire due to a mechanical issue or any other reason, the monthly hire received by the vessel owner is normally not impacted by such events. A bareboat charter contract contains only a lease component and revenue is recognized over the duration of such contract, as measured using the time that has elapsed from commencement of the lease. Hire is typically invoiced monthly in advance for bareboat charters, based on a fixed daily hire amount. Revenue is recognized in line with invoicing using the practical expedient in IFRS 15.B16. (v) Voyage Charters Voyage charters are charters for a specific voyage. Voyage charters for the Partnership’s shuttle tankers and towage vessels are priced on a current or “spot” market rate. The obligations within a voyage charter contract are satisfied as services are rendered over the duration of the voyage, as measured using the time that has elapsed from commencement of performance. In addition, expenses that are unique to a particular voyage, including any bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions, are the responsibility of the vessel owner. The Partnership’s voyage charters for shuttle tankers normally contain a lease, whereas for towage vessels such contracts do not normally contain a lease. Such determination involves judgment about the decision-making rights the charterer has under the contract. Consideration for such contracts is generally fixed; however, certain sources of variability exist. Delays caused by the charterer result in additional consideration. Payment for the voyage is not due until the voyage is completed. The duration of a single voyage will typically be less than three months and, as a result, the Partnership has applied the practical expedient in IFRS 15.121(a). The Partnership does not engage in any specific activities to minimize residual value risk due to the short-term nature of the contracts. Where the term of the contract is based on the duration of a single voyage, the Partnership uses a load-to-discharge basis in determining proportionate performance. Consequently, the Partnership does not begin recognizing revenue until a voyage charter has been agreed to by the customer and the Partnership, even if the vessel has discharged its prior cargo and is sailing to the anticipated load location for its next voyage. For towage voyages, proportionate performance is determined based on commencement of the tow to completion of the tow. The consolidated statements of financial position reflect, in Other assets, the accrued portion of revenues for those voyages that commence prior to the consolidated statement of financial position date and complete after the date of the consolidated statement of financial position and reflect, in Accounts payable and other, the deferred portion of revenues which will be earned in subsequent periods. (vi) Management Fees and Other The Partnership also generates revenues from the operation of volatile organic compounds (or VOC ) systems on certain of the Partnership’s shuttle tankers, and from the management of certain vessels on behalf of the disponent owners or charterers of these assets. Such services include the arrangement of third-party goods and services for the asset’s disponent owner or charterer. The obligations within these contracts typically consists of crewing, technical management, insurance and, potentially, commercial management. The obligations are satisfied concurrently and rendered over the duration of the management contract, as measured using the time that has elapsed from commencement of the contract. Consideration for such contracts generally consists of a fixed monthly management fee, plus the reimbursement of crewing costs for vessels being managed and all operational costs for the VOC systems. Management fees are typically invoiced monthly. Revenue is recognized in line with invoicing using the practical expedient in IFRS 15.B16.
Direct operating costs	Direct operating costs Direct operating cost include the following expenses: voyage expenses; operating expenses; charter hire and compensation. Voyage expenses are all expenses unique to a particular voyage, including bunker fuel expenses, port fees, cargo loading and unloading expenses, canal tolls, agency fees and commissions. Operating expenses include ship management services, repairs and maintenance, insurance, stores, lube oils and communication expenses. Charter hire expenses represent the cost to charter-in a vessel for a fixed period of time. Compensation includes the compensation costs for crewing and shore-based employees. Voyage expenses and operating expenses are recognized when incurred except when the Partnership incurs pre-operational costs related to the repositioning of a vessel that relates directly to a specific customer contract, that generates or enhances resources of the Partnership that will be used in satisfying performance obligations in the future, and where such costs are expected to be recovered via the customer contract. In this case, such costs are capitalized as contract costs and amortized over the duration of the customer contract. The Partnership recognizes operating leases from vessels chartered from other owners in charter hire expenses.
Financial instruments	Financial instruments Classification and measurement The table below summarizes the Partnership’s classification and measurement of financial assets and liabilities: Measurement Category Consolidated Statement of Financial Position Account Financial assets Cash and cash equivalents Amortized cost Cash and cash equivalents Restricted cash Amortized cost Financial assets Derivative instruments FVTPL Financial assets Other financial assets Amortized cost Financial assets Accounts receivable Amortized cost Accounts and other receivable, net Due from related parties Amortized cost Due from related parties Investment in finance leases Amortized cost Other assets Financial liabilities Accounts payable and other Amortized cost Accounts payable and other Derivative instruments FVTPL Other financial liabilities Obligations relating to leases Amortized cost Other financial liabilities Due to related parties Amortized cost Due to related parties Borrowings Amortized cost Borrowings The classification of financial assets depends on the specific business model for managing the financial assets and the contractual cash flow characteristics of the financial asset. At initial recognition, the Partnership measures a financial asset or liability at its fair value plus, in the case of a financial asset not at fair value through profit or loss (or FVTPL ), transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets and liabilities carried at FVTPL are expensed in Other income (expenses), net in the consolidated statements of income (loss). Financial assets are measured at amortized cost dependent on their contractual cash flow characteristics and the business model for which they are held. Financial assets classified as amortized cost are recorded initially at fair value, then subsequently measured at amortized cost using the effective interest rate method, less any impairment. Financial liabilities measured at amortized cost are initially recorded at fair value and, in the case of borrowings, net of directly attributable transaction costs. Financial liabilities are then subsequently measured at amortized cost using the effective interest rate method. Gains or losses are recognized in the consolidated statements of income (loss) when a financial asset or liability is remeasured due to a modification of terms that does not result in derecognition or when derecognition occurs and the modified financial instrument is recorded at fair value. Impairment The Partnership recognizes a loss allowance for expected credit losses (or ECL ) on financial assets measured subsequently at amortized cost, including trade receivables, amounts due from related parties, investments in finance leases and contract assets. The ECL is recognized upon inception of the financial asset and revised at each reporting date thereafter until maturity or disposal of the financial asset. The Partnership measures the loss allowance for a financial asset at an amount equal to the lifetime ECL if the credit risk on a financial asset has increased significantly since initial recognition. If the credit risk on a financial asset has not increased significantly, the Partnership measures the loss allowance for that financial instrument at an amount equal to the 12-months ECL. In making this assessment, the Partnership considers information that is reasonable and supportable, including historical experience and forward looking information that is available without undue cost or effort. The Partnership utilizes a simplified approach for measuring the loss allowance at an amount equal to the lifetime ECL for trade receivables, contract assets and investments in finance leases. The ECL on trade receivables are estimated by using reference to past default experience of the debtor and an analysis of the debtor’s current financial position, which also forms a basis for the Partnership's future expectations for potential defaults of the debtor. The ECL is presented as a direct reduction to the carrying value of the financial asset it relates to. The initial recognition of an ECL and all changes to an ECL at each reporting date thereafter are reflected in Other income (expenses), net in the consolidated statements of income (loss). As at December 31, 2021, the Partnership recorded an ECL of $0.6 million (December 31, 2020 - $1.4 million). Derivative instruments The Partnership selectively utilizes derivative financial instruments primarily to manage financial risks, including foreign exchange risks and interest rate risks. All derivative instruments are initially recorded at fair value as either assets or liabilities in the accompanying consolidated statements of financial position and subsequently remeasured to fair value, regardless of the purpose or intent for holding the derivative instrument. Hedge accounting is applied when the derivative is designated as a hedge of a specific exposure and there is assurance that it will continue to be highly effective as a hedge based on an expectation of offsetting cash flows or fair value. Hedge accounting is not applied if the hedge is not effective or will no longer be effective, the derivative was sold or exercised, or the hedged item was sold, repaid or is no longer probable of occurring. Hedge accounting is discontinued prospectively when the derivative no longer qualifies as a hedge or the hedging relationship is terminated. Once discontinued, the cumulative change in fair value of a derivative that was previously recorded in Other comprehensive income by the application of hedge accounting will be recognized in the Partnership's profit or loss over the remaining term of the original hedging relationship as amounts related to the hedged item are recognized in profit or loss. The Partnership has not designated, for accounting purposes, any derivatives as hedges of a specific exposure for all periods presented in these consolidated financial statements. For derivative financial instruments that are not designated as accounting hedges, the changes in the fair value of the derivative financial instruments are recognized in the profit or loss. Gains and losses from the Partnership’s non-designated foreign currency forward contracts and interest rate swaps are recorded in realized and unrealized gain (loss) on derivative instruments in the consolidated statements of income (loss). The assets or liabilities relating to unrealized mark-to-market gains and losses on derivative financial instruments are recorded in financial assets and other financial liabilities, respectively.
Fair value measurement	Fair value measurement Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, regardless of whether that price is directly observable or estimated using another valuation technique. In estimating the fair value of an asset or a liability, the Partnership takes into account the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date. Fair value measurement is disaggregated into three hierarchical levels: Level 1, 2 or 3. Fair value hierarchical levels are based on the degree to which the inputs to the fair value measurement are observable. The levels are as follows: Level 1 - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 - Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the asset’s or liability’s anticipated life. Level 3 - Inputs are unobservable and reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs in determining the estimate. Further information on fair value measurements is described in Note 3.
Income taxes	Income taxes The Partnership is subject to income taxes relating to its subsidiaries in Norway, Australia, Brazil, the United Kingdom, Singapore, Qatar, Canada, Luxembourg, the Netherlands, the Philippines and Thailand. (i) Current income tax Current income tax assets and liabilities are measured at the amount expected to be paid to tax authorities, net of recoveries based on the tax rates and laws enacted or substantively enacted at the reporting date. (ii) Deferred income tax Deferred income tax liabilities are provided for using the liability method on temporary differences between the tax bases used in the computation of taxable income and carrying amounts of assets and liabilities in the consolidated financial statements. Deferred income tax assets are recognized for all deductible temporary differences, carry forward of unused tax credits and unused tax losses, to the extent that it is probable that deductions, tax credits and tax losses can be utilized. Such deferred income tax assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the taxable income nor the accounting income, other than in a business combination. The carrying amount of deferred income tax assets are reviewed at each reporting date and reduced to the extent it is no longer probable that the income tax asset will be recovered. Deferred income tax liabilities are recognized for taxable temporary differences associated with equity-accounted investments, except where the Partnership is able to control the reversal of the temporary difference and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred income tax assets arising from deductible temporary differences associated with such investments are only recognized to the extent that it is probable that there will be sufficient taxable income against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future. Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates and tax laws that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred income tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Partnership expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. Deferred income tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority within a single taxable entity or the Partnership intends to settle its current tax assets and liabilities on a net basis in the case where there exist different taxable entities in the same taxation authority and when there is a legally enforceable right to set off current tax assets against current tax liabilities.
Provisions	Provisions Provisions are recognized when the Partnership has a present obligation, either legal or constructive, as a result of a past event, it is probable that the Partnership will be required to settle the obligation and a reliable estimate of the amount of the obligation can be made. Provisions are recorded within Accounts payable and other in the consolidated statements of financial position. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the obligation, its carrying amount is the present value of those cash flows. When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the receivable is recognized as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably. (i) Decommissioning liability The Partnership has a decommissioning liability related to the requirement to remove the sub-sea mooring and riser system associated with the Randgrid FSO unit and to restore the environment surrounding the facility. The costs associated with this decommissioning liability are to be reimbursed by the charterer, if certain conditions associated with the work are met. The obligation is expected to be settled at the end of the contract under which the FSO unit currently operates. The Partnership recognizes a decommissioning liability in the period in which it has a present legal or constructive liability and a reasonable estimate of the amount can be made. Liabilities are measured based on current requirements, technology and price levels and the present value is calculated using amounts discounted over the period for which the cash flows are expected to occur. Amounts are discounted using a rate that reflects the risks specific to the liability. On a periodic basis, management reviews these estimates and changes, if any, will be applied prospectively. The estimated decommissioning liability is recorded as a non-current liability, with a corresponding increase in the carrying amount of the related asset. As the decommissioning liability will be covered by contractual payments to be received from the charterer, the Partnership has recorded a separate receivable as a contract asset within Other assets . The liability and associated receivable are increased in each reporting period due to the passage of time, and the amount of accretion is charged to Other income (expense), net in the period. Periodic revisions to the estimated timing of cash flows, to the original estimated undiscounted cost and to changes in the discount rate can also result in an increase or decrease to the decommissioning liability and associated receivable. Actual costs incurred upon settlement of the obligation are recorded against the decommissioning liability to the extent of the liability recorded.
Assets held for sale	Assets held for sale Non-current assets and disposal groups are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is regarded as met only when the sale is highly probable and the non-current asset or disposal group is available for immediate sale in its present condition. Management must be committed to the sale, which should be expected to qualify for recognition as a completed sale within one year from the date of classification subject to limited exceptions. Non-current assets and disposal groups classified as held for sale are measured at the lower of their carrying amount and fair value less costs to sell and are classified as current. Once classified as held for sale, vessels and equipment are no longer depreciated.
Deferred financing costs	Deferred financing costsDeferred financing costs related to a borrowing, including bank fees, commissions and legal expenses, are deferred and amortized, over the term of the relevant loan facility, to interest expense using an effective interest rate method. Deferred financing costs are presented as a reduction from the carrying amount of the related financial liability, unless no amounts have been drawn under the debt liability or the debt issuance costs exceed the carrying value of the related debt liability, in which case the debt issuance costs are presented as Other non-current assets. If a debt modification is considered substantial, fees paid to amend an arrangement pursuant to which a credit facility is extinguished are associated with the extinguishment of the old debt instrument and included in determining the debt extinguishment gain or loss to be recognized. Any unamortized deferred financing costs are written off. If a debt modification is not considered substantial, then the fees are associated with the modification, along with any existing unamortized deferred financing costs and premium or discount, are including in calculation of the gain (loss) associated with the modification and remeasurement of the financial instrument resulting recognition of interest expense using the effective interest rate.
Critical accounting judgments and key sources of estimation uncertainty	Critical accounting judgments and key sources of estimation uncertainty The preparation of financial statements requires management to make critical judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses that are not readily apparent from other sources, during the reporting period. These estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods. Critical judgments and estimates made by management and utilized in the normal course of preparing the Partnership’s consolidated financial statements are outlined below. Critical accounting judgments (i) Determination of control The Partnership consolidates an investee when it controls the investee, with control existing if, and only if, the Partnership has (a) power over the investee, (b) exposure, or rights, to variable returns from involvement with the investee and (c) the ability to use that power over the investee to affect the amount of the Partnership’s returns. In determining if the Partnership has power over an investee, judgments are made when identifying which activities of the investee are relevant in significantly affecting returns of the investee and the extent of existing rights that give the Partnership the current ability to direct the relevant activities of the investee. Judgments are required to assess the Partnership's control over its non-wholly owned subsidiaries and investments in joint ventures. Judgments are made as to the amount of potential voting rights, the existence of contractual relationships that provide voting power and the ability for the Partnership to appoint directors. The Partnership enters into voting agreements which provide it the ability to contractually direct the relevant activities of the investee. In assessing if the Partnership has exposure, or rights, to variable returns from involvement with the investee, judgments are made concerning whether returns from an investee are variable and how variable those returns are on the basis of the substance of the arrangement, the size of those returns and the size of those returns relative to others, particularly in circumstances where the Partnership’s voting interest differs from the ownership interest in an investee. In determining if the Partnership has the ability to use its power over the investee to affect the amount of its returns, judgments are made when the Partnership is an investor as to whether it is a principal or agent and whether another entity with decision making rights is acting as the Partnership’s agent. If it is determined that the Partnership is acting as an agent, as opposed to a principal, the Partnership does not control the investee. See Note 2d(ii) for additional information. (ii) Lease classification and term At the inception of the charter, the classification of the lease as an operating lease or a finance lease may involve the use of judgment as to the determination of the lease term. Such judgment is required as the duration of certain of the Partnership's charters is unknown at commencement of the charter. The charterer may have the option to extend the charter or terminate the charter early. In addition, certain charters impose penalties on the charterer if it terminates the charter early and such penalties can vary in size depending on when, during the term of the charter, the termination right is exercised. Such penalties could impact the determination of the lease term and requires the use of judgment. (iii) Determination if a contract contains a lease Each vessel charter may, depending on its terms, contain a lease component, a non-lease component or both. Judgment is required in determining the composition of the lease and non-lease components of the Partnership's charters. The Partnership has determined the following for its charters: FPSO Contracts CoA (2) Time Charter Bareboat Charter Voyage Charter (1) Lease component Yes Yes Yes Yes Depends Non-lease component Yes Yes Yes No Depends (1) The Partnership believes that the conclusion as to whether or not a voyage charter contains a lease component rests principally on whether the customer has the substantive right to select and change the load and discharge ports. If the customer does not have this substantive right then the charter would not contain a lease component. The Partnership has categorized the charters for its shuttle tankers that are priced on spot market rates, and its towage vessels, as voyage charters Based on the conclusion above, the Partnership has determined that the contracts for its shuttle tankers classified as voyage charters normally contain a lease, wheras the contracts for its towage vessels do not normally contain a lease. (2) The Partnership has determined that as the relevant decisions about how and for what purpose the vessel is used are not predetermined under a CoA, but the customer has the right to make those relevant decisions, then the customer directs the use of the vessel. Based on this conclusion, the customer has the substantive right to select and change the load and discharge ports under a CoA charter and therefore the Partnership believes that a CoA charter contains a lease component, in addition to a non-lease component. The Partnership also generates revenues from the operation of VOC systems on certain of the Partnership’s shuttle tankers, and from the management of certain vessels on behalf of the disponent owners or charterers of these assets. The Partnership has determined that as the leasing of its VOC equipment is classified as a finance lease, the finance income associated with these leases are recognized as lease income. Additionally, as the contracts pertaining to the management of certain vessels on behalf of the disponent owners or charterers of these assets do not contain an identified asset, the Partnership believes that these do not contain a lease. For charters which contain both, the Partnership has allocated the contract consideration between the lease component and non-lease component on a relative standalone selling price basis. Given that there are no observable standalone selling prices for either of these two components, judgment is required in determining the standalone selling price of each component. The standalone selling price of the non-lease component has been determined using a cost-plus approach, whereby the Partnership estimates the cost to operate the unit using internal estimates, plus a profit margin. The standalone selling price of the lease component has been determined using an adjusted market approach, whereby the Partnership calculates a rate excluding the operating component based on a market rate from published broker estimates, when available, or internal estimates when not available. (iv) Impairment Judgment is applied when determining whether indicators of impairment exist when assessing the carrying values of the Partnership’s assets, the likelihood the Partnership will sell the vessel or equipment prior to the end of its useful life, the estimation of a cash generating units future revenues and direct costs, and the determination of discount rates. The Partnership has determined that, as the cash inflows of the individual vessels in its CoA fleet are not largely independent from each other, the CoA fleet is treated as a single cash generating unit for impairment purposes. Estimation uncertainty (i) Decommissioning liabilities Decommissioning costs will be incurred at the end of the operating life of one of the Partnership’s vessels. This obligation is often many years in the future and requires judgment to estimate. The estimate of decommissioning costs can vary in response to many factors including changes in relevant legal, regulatory, and environmental requirements, the emergence of new restoration techniques or experience at other production sites. Inherent in the calculations of these costs are assumptions and estimates including the ultimate settlement amounts, inflation factors, discount rates, and timing of settlements. See Notes 2s(i) and 14 for additional information. (ii) Vessels and equipment - useful lives and residual value The cost of the Partnership's vessels and equipment are depreciated on a straight-line basis over each asset's estimated useful life to an estimated residual value. The estimated useful life of the Partnership's vessels, including individual components, takes into account design life, commercial considerations and regulatory restrictions. The determination of the components, if any, of an asset and the estimated useful life of such asset or components involves judgment. See Note 2j for additional information. (iii) Impairment The recoverable amounts of each vessel, being defined as a cash-generating unit, is the higher of its fair value less cost of disposal and its value in use. The fair value less cost of disposal calculation is based on the discounted cash flow model and is the same as the value in use. Value in use calculations are based on contracted cash flows and estimates of uncontracted cash flows for the useful lives of each vessel, including residual values discounted by an estimated discount rate. Assumptions on uncontracted cash flows are based on several variables, such as comparing the specifications on a particular vessel with planned new projects around the world, assessment of investment levels to redeploy the vessel on a new field and assumptions on rates to be achieved from redeployment. The key assumptions used for the impairment testing of our fleet are described in Note 10. All impairment assessment calculations demand a high degree of estimation. The Partnership must make complex assessment of the expected cash flows arising from such assets and the selection of discount rates. Changes to these estimates could have significant impact on the impairments recognized and future changes may lead to reversals of recognized impairments. See Notes 10 and 13 for additional information. (iv) Taxes The future realization of deferred tax assets depends on the existence of sufficient taxable income to utilize tax losses. This analysis requires, among other things, the use of estimates and projections in determining future reversals of temporary differences, forecasts of future profitability and evaluating potential tax-planning strategies. (v) Going concern The Partnership's assessment of its ability to continue operating on a going concern basis requires judgment and the estimation of the probability in obtaining additional sources of financing to meet its obligations and commitments and minimum liquidity requirements under its financial covenants. See Note 2(b) for additional information. (vi) COVID-19 In March 2020, the World Health Organization declared a global pandemic related to COVID-19. To date, there has been significant volatility in capital markets, commodity prices and foreign currencies, restrictions on the conduct of business in many jurisdictions, and the global movement of people and some goods has become restricted. The Partnership considered the impacts of these circumstances on the key critical judgments, estimates and assumptions that affect the reported and contingent amount of assets, liabilities, revenues and expenses, including whether any additional indicators of impairment were present for the year ended December 31, 2021. Based on the Partnership’s assessments, no additional impairment indicators were identified as at December 31, 2021 and the Partnership has not experienced any material business interruptions or financial impact as a result of the COVID-19 pandemic. The extent to which the COVID-19 pandemic may impact the Partnership's results of operations and financial condition, including any future possible impairments, will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus or its variants, the effectiveness of vaccines and other actions to contain or treat its impact, among others. The Partnership will continue to monitor the situation and review its critical estimates and judgments as circumstances evolve. (vii) Climate Change
Earnings (loss) per Limited Partnership Unit	Earnings (loss) per Limited Partnership Unit The Partnership calculates basic earnings (loss) per unit by dividing net income (loss) attributable to limited partners by the weighted average number of limited partnership common units outstanding during the period. The net income (loss) attributable to limited partners is allocated between the Class A and Class B limited partners' based on their proportionate ownership percentages. Basic earnings (loss) per unit has been presented on an aggregate basis and includes net income (loss) attributable to Class A limited partners and net income (loss) attributable Class B limited partners, which, if disaggregated, would not have a material effect. For the purpose of calculating diluted earnings (loss) per unit, the Partnership adjusts net income (loss) attributable to limited partners, and the weighted average number of limited partnership common units outstanding, for the effects of all dilutive potential limited partnership common units, consisting of restricted common units and any warrants exercisable for common units. Consequently, the weighted average number of common units outstanding is increased assuming conversion of the restricted units and exercise of the warrants using the treasury stock method. The computation of diluted earnings (loss) per unit does not assume the issuance of common units if the effect would be anti-dilutive.
Segments	Segments The Partnership’s operating segments are components of the business for which discrete financial information is reviewed regularly by the Chief Operating Decision Maker (or CODM ) to assess performance and make decisions regarding resource allocation. The Partnership has assessed the CODM to be its Chief Executive Officer. As at December 31, 2021, the Partnership’s operating segments are the FPSO, Shuttle Tanker, FSO, UMS and Towage segments. As at January 1, 2021, the Partnership modified the cost allocations between its operating segments. The Partnership's components of the business for which discrete financial information is reviewed to assess performance and make decisions regarding resource allocation is still based upon five operating segments. However, the allocation of certain expenditures, relating to direct operating costs and general and administrative expenses, has been modified to show the impact of certain corporate direct operating costs in the corporate segment before reallocation to the operating segments. Additionally, certain expenditures that relate directly to corporate activities will be retained within the corporate segment. Previously all of these expenditures were allocated directly to the five operating segments based on an estimated use of corporate resources. The 2020 and 2019 comparative information has been restated as a result of this change and the modifications have been deemed to not be material for all operating segments and all periods presented.
Employee Pension Plans	Employee Pension Plans The Partnership has defined contribution pension plans covering the majority of its employees. Pension costs associated with the Partnership’s required contributions under its defined contribution pension plans are based on a percentage of employees’ salaries and are charged to earnings in the year incurred. During the year ended December 31, 2021, the amount of cost recognized for the Partnership’s defined contribution pension plans was $6.6 million (December 31, 2020 - $5.5 million, December 31, 2019 - $5.2 million). The Partnership also has defined benefit pension plans covering a small number of active and retired employees in Norway. The Partnership accrues the costs and related obligations associated with its defined benefit pension plans based on actuarial computations using the projected benefits obligation method and management’s best estimates of expected plan investment performance, salary escalation, and other relevant factors. For the purpose of calculating the expected return on plan assets, those assets are valued at fair value. The overfunded or underfunded status of the defined benefit pension plans is recognized as assets or liabilities in the consolidated statements of financial position. The Partnership recognizes as a component of Other comprehensive income (loss), the gains or losses that arise during a period but that are not recognized as part of net periodic benefit costs. The pension assets have been guaranteed a minimum rate of return by the provider, thus reducing potential exposure to the Partnership to the extent the provider honors its obligations. The Partnership's funded status relating to its defined benefit pension plans was a shortfall of $0.8 million as at December 31, 2021 (December 31, 2020 - a shortfall of $0.7 million).
New standards, interpretations, amendments and policies adopted by the Partnership	New standards, interpretations, amendments and policies adopted by the Partnership The Partnership has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective. i. Interest Rate Benchmark Reform — Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16) In August 2020, the International Accounting Standards Board published Interest Rate Benchmark Reform — Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16) (or Phase 2 Amendments ), effective January 1, 2021. The Phase 2 Amendments provide additional guidance to address the issues that will arise during the transition of benchmark interest rates and primarily relate to the modification of financial assets, financial liabilities and lease liabilities where the basis for determining the contractual cash flow changes as a result of the replacement of an existing interest rate benchmark, allowing for prospective application of the new applicable benchmark interest rate, and to the application of hedge accounting, providing an exception such that changes in the designation of hedge accounting relationships that are needed to reflect the changes required by the benchmark interest rate reform do not result in the discontinuation of hedge accounting. The Partnership adopted the Phase 2 Amendments on January 1, 2021. The adoption of the amendments did not have a significant impact on the Partnership’s consolidated financial statements as at and for the year ended December 31, 2021. The Partnership's risk management strategy has not changed as a result of these matters. Progress towards implementation of alternative benchmark interest rates The Partnership is exposed to the impact of interest rate changes, primarily through its floating-rate borrowings that require it to make interest payments based on LIBOR. The Partnership uses interest rate swaps to reduce its exposure to market risk from changes in interest rates. The Partnership plans to transition the majority of its LIBOR-linked contracts to risk-free rates through amendments to fallback clauses in its floating-rate credit facilities and debt instruments which would change the basis for determining the interest rate cash flows from LIBOR to a risk-free rate at an agreed point in time. During March 2021, ICE Benchmark Administration, an administrator of regulated benchmarks, announced that it has delayed the cessation of the publication of the overnight, one, three, six and 12 month USD LIBOR until June 30, 2023. Interest rate benchmark transition for non-derivative financial liabilities As at December 31, 2021, the Partnership had $1.6 billion of outstanding LIBOR-referenced borrowings summarized as follows: Principal Weighted-average term Transition Progress $ (years) Revolving Credit Facilities 308,887 2.34 Expected to amend fallback clauses prior to cessation of publication of LIBOR. Term Loans 1,079,586 3.92 Public Bonds 200,000 2.80 Total 1,588,473 3.48 Interest rate benchmark transition for derivatives As at December 31, 2021, the Partnership had an outstanding notional balance of $541.6 million of LIBOR-referenced interest rate swap agreements. For all of the Partnership’s LIBOR-referenced derivatives, the International Swaps and Derivative Association’s fallback clauses were made available in late-2020 and the Partnership and its counterparties expect to adhere to this protocol. Such adherence would result in all legacy trade under the derivatives following, on the cessation of LIBOR, the fallback clause provided in the protocol. ii. Classification of Liabilities as Current or Non-current (Amendments to IAS 1) In January 2020, the International Accounting Standards Board finalized amendments to IAS 1 to clarify the classification of liabilities. The amendments affect only the presentation of liabilities in the statement of financial position and not the amount or timing of recognition of any asset, liability income or expenses, or the information that entities disclose about those items. They: • clarify that the classification of liabilities as current or non-current should be based on rights that are in existence at the end of the reporting period and align the wording in all affected paragraphs to refer to the "right" to defer settlement by at least twelve months and make explicit that only rights in place "at the end of the reporting period" should affect the classification of a liability; • clarify that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of a liability; and • make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services.

Summary of vessels and equipment estimated useful life	Vessels and equipment are depreciated for each component of the asset classes as follows: Component Estimated Useful Life Dry docks and Overhauls 2.5 - 5 years Capital Modifications (1) 3 - 20 years Vessels and Equipment (2) 9 - 35 years (1) Includes field and contract specific equipment for the Partnership's FPSO units and FSO units, capital upgrades for the Partnership's shuttle tankers and mid-life refurbishments for the Partnership's UMS. (2) Certain of the Partnership's FPSO units and FSO units have undergone conversions or capital upgrades prior to commencing operations under their current contracts. The estimated useful lives of such vessels is generally substantially lower than that of a comparable newbuilding vessel. For a newbuilding vessel, the Partnership uses an estimated useful life of 20 to 25 years for its FPSO units, 20 years for its shuttle tankers, 35 years for its UMS and 25 years for its towage and offshore installation (or Towage ) vessels. The estimated useful life of the Partnership's FSO units are generally the contract term for the unit, inclusive of extension options.

Disclosure of detailed information about fair value measurement hierarchical levels	Fair value hierarchical levels are based on the degree to which the inputs to the fair value measurement are observable. The levels are as follows: Level 1 - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 - Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the asset’s or liability’s anticipated life. Level 3 - Inputs are unobservable and reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs in determining the estimate.
Summary of judgement required in determining the composition of the lease and non-lease components of charters	The Partnership has determined the following for its charters: FPSO Contracts CoA (2) Time Charter Bareboat Charter Voyage Charter (1) Lease component Yes Yes Yes Yes Depends Non-lease component Yes Yes Yes No Depends (1) The Partnership believes that the conclusion as to whether or not a voyage charter contains a lease component rests principally on whether the customer has the substantive right to select and change the load and discharge ports. If the customer does not have this substantive right then the charter would not contain a lease component. The Partnership has categorized the charters for its shuttle tankers that are priced on spot market rates, and its towage vessels, as voyage charters Based on the conclusion above, the Partnership has determined that the contracts for its shuttle tankers classified as voyage charters normally contain a lease, wheras the contracts for its towage vessels do not normally contain a lease. (2) The Partnership has determined that as the relevant decisions about how and for what purpose the vessel is used are not predetermined under a CoA, but the customer has the right to make those relevant decisions, then the customer directs the use of the vessel. Based on this conclusion, the customer has the substantive right to select and change the load and discharge ports under a CoA charter and therefore the Partnership believes that a CoA charter contains a lease component, in addition to a non-lease component.

Jan Rune Steinsland Chief Financial Officer, Altera Infrastructure Group Ltd. Duncan Donaldson General Counsel, Altera Infrastructure Group Ltd. For the years ended December 31, 2021, 2020 and 2019 the total compensation expenses of these three key management personnel of the Partnership are as follows: Salary Bonus Pension Benefits Other Benefits Total Compensation 2021 1,585 1,788 93 70 3,536 2020 1,317 1,570 88 88 3,063 2019 1,218 595 81 146 2,040 The Partnership is a party to the following transactions with related parties: a) On August 27, 2021, a wholly owned subsidiary of the Partnership, Altera Infrastructure Holdings L.L.C., as issuer, and the Partnership, as parent guarantor, entered into an agreement to exchange an aggregate of $699.3 million of indebtedness in the Partnership with interest rates ranging from 5.00% to 11.50% and with maturities ranging from 2022 to 2024 (the Brookfield Exchanges ). The exchanges included $415.2 million in aggregate principal amount of the 8.50% Senior Notes, $236.9 million in aggregate principal amount of loans relating to an unsecured revolving credit facility provided by Brookfield, which was due to mature in October 2024, $30.0 million in aggregate principal amount of loans relating to an unsecured revolving credit facility provided by Brookfield, which was due to mature in February 2022, and $17.2 million in aggregate principal amount of loans relating to an unsecured revolving credit facility provided by Brookfield, which was due to mature in July 2022, in each case for newly issued 11.50% Senior Secured PIK Notes due August 2026 in an equal aggregate principal amount. As at December 31, 2021, the Partnership has accrued a total of $27.7 million of PIK interest, increasing the principal amount of the 11.50% PIK Notes in an amount equal to the interest. Any outstanding principal balances are due on the maturity date. On July 2, 2018, the Partnership issued, in a U.S. private placement, a total of $700.0 million senior unsecured bonds due in July 2023. The interest payments on the bonds were fixed at a rate 8.50% (see Note 19 for additional information). Brookfield purchased $500.0 million of these bonds and as at the date of the Brookfield Exchanges, August 27, 2021, Brookfield held $411.3 million of these bonds (December 31, 2020 - $411.3 million). As part of the Brookfield Exchanges, Altera Infrastructure Holdings L.L.C. issued to Brookfield additional 11.50% PIK Notes in an aggregate principal amount equal to the $4.0 million then accrued and unpaid interest under the exchanged 8.50% Senior Notes. Consistent with the Partnership’s new accounting policy election in August 2021, these notes have been retrospectively reclassified from Borrowings (non-current) to Due to related parties (non-current) on the Partnership's consolidated statements of financial position. Please refer to Note 2i for additional information. As of August 27, 2021, the date of the Brookfield Exchanges, the Partnership had an undrawn balance of $nil (December 31, 2020 - $nil) relating to an unsecured revolving credit facility provided by Brookfield, which had previously provided for borrowings of up to $225.0 million and matured on October 31, 2024. The interest payments on the facility were based on LIBOR plus a margin of 5.00%. The facility provided the Partnership the option to defer interest payments of up to $25.0 million until maturity. As at August 27, 2021, the Partnership had deferred a total of $11.9 million of interest payments, which deferred interest was exchanged for the issuance to Brookfield as part of the Brookfield Exchanges of additional 11.50% PIK Notes with an aggregate principal amount of $11.9 million. The Partnership had previously determined that, as the interest rate under the revolving credit facility was deemed to be at below market terms, Brookfield was acting in its capacity as an equity owner and the Partnership recorded a $37.1 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's consolidated statements of changes in equity during the year ended December 31, 2020. As a result of the Brookfield Exchanges, the Partnership determined that the 11.50% PIK Notes were issued at fair value and therefore the then-remaining unamortized discount of $28.0 million was recorded as a loss through Gain (loss) on modification of financial liabilities, net on the Partnership’s consolidated statements of income (loss) during the year ended December 31, 2021. Prior to the Brookfield Exchanges, during the year ended December 31, 2021, the Partnership entered into an unsecured revolving credit facility provided by Brookfield, which had previously provided for borrowings of up to $30.0 million and as at the date of the Brookfield Exchanges, August 27, 2021, was fully drawn. The interest payments on the facility were based on LIBOR plus a margin of 5.00% and the facility matured in February 2022. Any outstanding principal balances were due on the maturity date. During the year ended December 31, 2021, the Partnership determined that the interest rate under the facility was deemed to be at below market terms and therefore, Brookfield was acting in its capacity as an equity owner. The Partnership recorded a $1.3 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's consolidated statements of changes in equity during the year ended December 31, 2021. As a result of the Brookfield Exchanges, the Partnership determined that the 11.50% PIK Notes were issued at fair value and therefore the then-remaining unamortized discount of $0.5 million was recorded as a loss through Gain (loss) on modification of financial liabilities, net on the Partnership’s consolidated statements of income (loss) during the year ended December 31, 2021. Prior to the Brookfield Exchanges, during the year ended December 31, 2021, a subsidiary of the Partnership entered into an unsecured revolving credit facility provided by Brookfield, which had previously provided for borrowings of up to $17.0 million and as at the date of the Brookfield Exchanges, August 27, 2021, was fully drawn. Borrowings under the facility bore interest solely in kind at a rate of 11.50% per annum. The facility had a maturity date of July 2022. Any outstanding principal balances were due on the maturity date. As part of the Brookfield Exchanges, Holdco issued to Brookfield additional 11.50% PIK Notes with an aggregate principal amount of $0.2 million, equal to the then accrued and unpaid interest under the term loan facility. b) On December 14, 2021, a wholly owned subsidiary of the Partnership, Altera Shuttle Tankers L.L.C., entered into an agreement with Brookfield to issue $70.0 million aggregate principal amount unsecured PIK notes (or the 12.50% PIK Notes ), which contemporaneously discharged the then-existing $70.0 million unsecured revolving credit facility which was fully drawn, accrued interest at a rate equal to LIBOR plus a margin of 5.00% and was due to mature in February 2022. Interest under the 12.50% Notes is payable in kind at a fixed rate of 12.50% and the facility matures in June 2026. The 12.50% PIK Notes are to be listed on The International Stock Exchange. Additional 12.50% PIK Notes may only be issued to satisfy the interest payable under the notes. As at December 31, 2021, the Partnership has accrued a total of $0.5 million of PIK interest, increasing the outstanding principal amount of the 12.50% PIK Notes in an amount equal to the interest. Any outstanding principal balances are due on the maturity date. During the year ended December 31, 2021, the Partnership determined that the interest rate under the $70.0 million revolving credit facility described above was deemed to be at below market terms and therefore, Brookfield was acting in its capacity as an equity owner. The Partnership recorded a $0.6 million decrease in the carrying value of the facility, which was classified as an equity contribution in the Partnership's consolidated statements of changes in equity during the year ended December 31, 2021. consolidated statements of income (loss) were as follows for the periods indicated: Year Ended December 31, 2021 2020 2019 Revenues (1) 9,414 8,079 42,628 Direct operating costs (2) — — (2,535) General and administrative expenses (3) (1,119) (1,134) (8,811) Depreciation and amortization (209) (209) — Interest expense (4)(5)(6) (69,695) (43,831) (46,101) Realized and unrealized gain (loss) on derivative instruments (7) — — 49,832 Gain (loss) on modification of financial liabilities, net (8) (28,517) — (1,949) (1) Includes revenue from services provided to the Partnership's equity-accounted investments and from time-charter-out or bareboat contracts with subsidiaries of Teekay Corporation, including management fees for ship management services provided by the Partnership to a subsidiary of Teekay Corporation prior to May 8, 2019.
