Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies (a) Principles of Consolidation (b) Use of Estimates : The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the amounts of revenues and expenses recognized during the reporting period. Actual results could differ from those estimates. (c) Accounting for Revenue, Voyage and Operating Expenses Time charters contracts A time charter is a contract for the use of a vessel for a specific period of time and a specified daily charter hire rate, which is generally payable in advance. A time charter generally provides typical warranties and owner protective restrictions. The performance obligations in a time charter are satisfied over the term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the owner of the vessel. The time charter contracts are considered operating leases because (i) the vessel is an identifiable asset (ii) the owner of the vessel does not have substantive substitution rights and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use. Revenues from time charters are recognized ratably on a straight-line basis over the period of the respective charter. Under time charter agreements, all voyage expenses, except commissions are assumed by the charterer. Operating costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance and lubricants are paid by the Partnership under time charter agreements. Voyage charters contracts A voyage charter is a contract in which the vessel owner undertakes to transport a specific amount and type of cargo on a load port-to-discharge port basis, subject to various cargo handling terms. The Partnership accounts for a voyage charter when all the following criteria are met: (1) the parties to the contract have approved the contract in the form of a written charter agreement and are committed to perform their respective obligations, (2) the Partnership can identify each party’s rights regarding the services to be transferred, (3) the Partnership can identify the payment terms for the services to be transferred, (4) the charter agreement has commercial substance (that is, the risk, timing, or amount of the Partnership’s future cash flows is expected to change as a result of the contract) and (5) it is probable that the Partnership will collect substantially all of the consideration to which it will be entitled in exchange for the services that will be transferred to the charterer. The Partnership determined that its voyage charters consist of a single performance obligation which is met evenly as the voyage progresses and begin to be satisfied once the vessel is ready to load the cargo. The voyage charter party agreement generally has a demurrage/dispatch clause according to which in the case of demurrage, the charterer reimburses the vessel owner for any potential delays exceeding the allowed lay time as per the charter party clause at the ports visited which is recorded as demurrage revenue. In the case of dispatch, the owner reimburses the charterer for the earlier discharging of the cargo from the agreed time. Demurrage/dispatch revenues are recognized starting from the point that is determined that the amount can be estimated, and its collection/payment is probable and on a straight-line basis until the end of the voyage. Revenues from voyage charters are recognized on a straight-line basis over the voyage duration which commences once the vessel is ready to load the cargo and terminates upon the completion of the discharge of the cargo. Under Accounting Standards Codification (“ASC”) 606, receivables represent an entity’s unconditional right to consideration, whether billed or unbilled In voyage charters, vessel operating, and voyage expenses are paid for by the Partnership. The voyage charters are considered service contracts which fall under the provisions of ASC 606 because the Partnership retains control over the operations of the vessels such as the routes taken or the vessels’ speed. Payment terms under voyage charters are disclosed in the relevant voyage charter agreements and generally have standard payment terms of 90% to 95% of the freight which is paid within three days after the completion of the vessel’s loading. 2. Significant Accounting Policies – Continued (c) Accounting for Revenue, Voyage and Operating Expenses - Continued: Vessel voyage expenses are direct expenses to voyage revenues and primarily consist of brokerage commissions, port expenses, canal dues and bunkers. Brokerage commissions are paid to shipbrokers for their time and efforts for negotiating and arranging charter party agreements on behalf of the Partnership and are expensed over the related charter period. All other voyage expenses are expensed as incurred, except for expenses during the ballast portion of the voyage (period between the contract date and the date of the vessel’s arrival to the load port). Any expenses incurred during the ballast portion of the voyage such as bunker expenses, canal tolls and port expenses are deferred and are recognized on a straight-line basis, in voyage expenses, over the voyage duration as the Partnership satisfies the performance obligations under the contract provided these costs are (1) incurred to fulfill a contract that we can specifically identify, (2) able to generate or enhance resources of the company that will be used to satisfy performance of the terms of the contract, and (3) expected to be recovered from the charterer. These costs are considered ‘contract fulfillment costs’ and are included in ‘prepayments and other assets’ in the consolidated balance sheets. Vessel operating expenses presented in the consolidated financial statements mainly consist of management fees payable to the Partnership’s managers and crew, repairs and maintenance, insurance, stores, spares, lubricants, and other operating expenses. Vessel operating expenses are expensed as incurred. (d) Foreign Currency Transactions (e) Cash and Cash Equivalents : The Partnership considers highly liquid investments such as time deposits and certificates of deposit with an original maturity of three months or less to be cash equivalents. (f) Restricted cash : For the Partnership to comply with debt covenants under its credit facilities and financing arrangements, it must maintain minimum cash deposits. Such deposits are considered by the Partnership to be restricted cash. (g) Trade Accounts Receivable 113 174 (h) Inventories (i) Vessels Held for Sale Vessels classified as held for sale are measured at the lower of their carrying amount or fair value less costs to sell. These vessels are not depreciated once they meet the criteria to be classified as held for sale. If a plan to sell a vessel is cancelled, the Partnership reclassifies the vessel as held for use and re-measures it at the lower of (i) its carrying amount before the vessel was classified as held for sale, adjusted for any depreciation expense that would have been recognized if the vessel had been continuously classified as held and used and (ii) its fair value at the date of the subsequent decision not to sell. 2. Significant Accounting Policies – Continued (j) Fixed Assets straight-line 0.2 25 35 (k) Impairment of Vessels (l) Deferred charges, net thirty sixty (m) Intangible assets (n) Net Income Per Limited Partner Unit (o) Segment Reporting one 2. Significant Accounting Policies – Continued (p) Omnibus Incentive Compensation Plan (q) Treasury stock : The Partnership records the repurchase of its common units at cost based on the settlement dates of repurchase transactions. These units are classified as treasury units, which is a reduction to partners’ capital. Treasury units are included in authorized and issued units but excluded from outstanding units (Note 13). (r) Derivative Instruments (s) Recent Accounting Pronouncements On January 7, 2021, The Financial Accounting Standards Board issued the Accounting Standards Update (“ASU”) No. 2021-01—Reference Rate Reform (Topic 848). The amendments in this Update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments in this Update to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. This ASU is effective for adoption at any time between January 7, 2021 and December 31, 2022. The Partnership is currently evaluating the impact of this adoption in its consolidated financial statements and related disclosures.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	9. Financial Instruments (a) Fair value of financial instruments The Partnership follows the accounting guidance for financial instruments that establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosure about fair value measurements. This guidance enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. The statement requires that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; Level 2: Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and Level 3: Inputs are unobservable inputs for the asset or liability. The carrying value of cash and cash equivalents and restricted cash, are considered Level 1 items as they represent liquid assets with short-term maturities, trade receivables, amounts due to related parties, trade accounts payable and accrued liabilities approximate their fair value. The fair value of variable rate long-term debt (Note 8) approximates the recorded value, due to its variable interest being the LIBOR and due to the fact the lenders have the ability to pass on their funding cost to the Partnership under certain circumstances, which reflects their current assessed risk. We believe the terms of our loans are similar to those that could be procured as of December 31, 2021. LIBOR rates are observable at commonly quoted intervals for the full term of the loans and hence bank loans are considered Level 2 items in accordance with the fair value hierarchy. The fair value of the fixed rate long term debt (Note 8-(iii),(iv),(v) and (xix)) was approximately $ 158,290 The Bonds have a fixed rate, and their estimated fair values as of December 31, 2021 were determined through Level 1 inputs of the fair value hierarchy (quoted price under the ticker symbol CPLPB1 on Athens Stock Exchange) and were approximately $ 171,292 There were no Level 3 items. 9. Financial Instruments - Continued Derivative instruments In connection with the issuance of the Bonds (Note 8), the Partnership entered into certain cross-currency swap agreements to manage the related foreign currency exchange risk by effectively converting the fixed-rate, Euro-denominated Bonds, including the semi-annual interest payments for the period from October 21, 2021 to October 21, 2025 to fixed-rate, U.S. Dollar-denominated debt. The economic effect of the swap agreements is to eliminate the uncertainty of the cash flows in U.S. Dollars associated with the issuance of the Bonds by fixing the principal amount of the Bonds, with a fixed annual interest rate. The cross-currency swap agreements were not designated as accounting hedges. Derivative instruments not designated as hedges are not speculative and are used to manage the Partnership’s exposure to identified risks but do not meet the strict hedge accounting requirements and/or the Partnership has not elected to apply hedge accounting.

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes Under the laws of the Marshall Islands and Liberia, the countries in which the vessel-owning subsidiaries were incorporated, these companies are not subject to tax on international shipping income. However, they are subject to registration and tonnage taxes in the country in which the vessels are registered and managed from, and such taxes have been included in “Vessel operating expenses” in the consolidated statements of comprehensive income / (loss). Pursuant to Section 883 of the United States Internal Revenue Code (the “Code”) and the regulations thereunder, a foreign corporation engaged in the international operation of ships is generally exempt from U.S. federal income tax on its U.S.-source shipping income if the foreign corporation meets both of the following requirements: (a) the foreign corporation is organized in a foreign country that grants an “equivalent exemption” to corporations organized in the United States for the types of shipping income (e.g., voyage and time charter) earned by the foreign corporation and (b) more than 50% of the voting power and value of the foreign corporation’s stock is “primarily and regularly traded on an established securities market” in the United States and certain other requirements are satisfied (the “Publicly-Traded Test”). Each of the jurisdictions where the Partnership’s vessel-owning subsidiaries are incorporated grants an “equivalent exemption” to United States corporations with respect to each type of shipping income earned by the Partnership’s vessel-owning subsidiaries. Additionally, our units are only traded on the Nasdaq Global Market, which is considered to be established securities market. The Partnership has satisfied the Publicly-Traded Test for the years ended December 31, 2021, 2020 and 2019 and the vessel-owning subsidiaries are exempt from United States federal income taxation with respect to U.S.-source shipping income. CPLP PLC is incorporated in Cyprus and does not conduct any substantive operations of its own. No provision for Cyprus income tax has been made in the financial statements as CPLP PLC had no assessable income for the period from August 14, 2021 (inception) to December 31, 2021.

Equity [Abstract]
Partners’ Capital	13. Partners’ Capital General: Definition of Available Cash: • less the amount of cash reserves established by our board of directors to: • provide for the proper conduct of the Partnership’s business (including reserves for future capital expenditures and for our anticipated credit needs); • comply with applicable law, any of the Partnership’s debt instruments, or other agreements; or • provide funds for distributions to the Partnership’s unit holders and to the general partner for any one or more of the next four quarters; • plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter. Working capital borrowings are generally borrowings that are made under our credit agreements and in all cases are used solely for working capital purposes or to pay distributions to partners subject to certain exceptions set forth in the Partnership Agreement. General Partner Interest and IDRs: 1.77% IDRs represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. According to the Partnership Agreement, as amended in 2014, the following table illustrates the percentage allocations of the additional available cash from operating surplus among the unit holders and general partner up to the various target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of the unit holders and general partner in any available cash from operating surplus that is being distributed up to and including the corresponding amount in the column “Total Quarterly Distribution Target Amount per Unit,” until available cash from operating surplus the Partnership distributes reaches the next target distribution level, if any. The percentage interests shown for the unit holders and general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests shown below assume that the Partnership’s general partner maintains a 2% general partner interest and that it has not transferred its IDR.

Earnings Per Share [Abstract]
Net Income from continuing operations Per Unit	15. Net Income from continuing operations Per Unit The general partner’s and common unit holders’ interests in net income are calculated as if all net income for periods subsequent to April 4, 2007, were distributed according to the terms of the Partnership Agreement, regardless of whether those earnings would or could be distributed. The Partnership Agreement does not provide for the distribution of net income; rather, it provides for the distribution of available cash (Note 13), which is a contractually-defined term that generally means all cash on hand at the end of each quarter after establishment of cash reserves determined by the Partnership’s board of directors to provide for the proper resources for the Partnership’s business. Unlike available cash, net income is affected by non-cash items. The Partnership follows the guidance relating to the Application of the Two-Class Method and its application to Master Limited Partnerships, which considers whether the incentive distributions of a master limited partnership represent a participating security when considered in the calculation of earnings per unit under the Two-Class Method. The Partnership also considers whether the Partnership Agreement contains any contractual limitations concerning distributions to the IDRs that would impact the amount of earnings to allocate to the IDRs for each reporting period. Under the Partnership Agreement, the holder of the IDRs in the Partnership, which is currently CGP, assuming that there are no cumulative arrearages on common unit distributions, has the right to receive an increasing percentage of cash distributions (Note 13). The Partnership excluded the effect of the 12,983,333 For the year ended December 31, 2021, the Partnership excluded the effect of 412,916 412,916 428,958 The non-vested units were participating securities because they received distributions from the Partnership and these distributions did not have to be returned to the Partnership if the non-vested units were forfeited by the grantee. The Partnership’s net income for the years ended December 31, 2021, 2020 and 2019 did not exceed the First Target Distribution Level, and as a result, the assumed distribution of net income did not result in the use of increasing percentages to calculate CGP’s interest in net income. 15.

Commitments and Contingencies	16. Commitments and Contingencies Contingencies Various claims, suits, and complaints, including those involving government regulations and product liability, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, agents, insurance and other claims with suppliers relating to the operations of the Partnership’s vessels. The Partnership accrues for the cost of environmental liabilities when management becomes aware that a liability is probable and is able to reasonably estimate the probable exposure. An estimated loss from a contingency should be accrued by a charge to expense and a liability recorded only if all of the following conditions are met: • Information available prior to the issuance of the financial statement indicates that it is probable that a liability has been incurred at the date of the financial statements. • The amount of the loss can be reasonably estimated. Currently, the Partnership is not aware of any such claims or contingent liabilities which should be disclosed or for which a provision should be established in the consolidated financial statements. 16.

Accounting Policies [Abstract]
Principles of Consolidation	(a) Principles of Consolidation
Use of Estimates	(b) Use of Estimates : The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the amounts of revenues and expenses recognized during the reporting period. Actual results could differ from those estimates.
Accounting for Revenue, Voyage and Operating Expenses	(c) Accounting for Revenue, Voyage and Operating Expenses Time charters contracts A time charter is a contract for the use of a vessel for a specific period of time and a specified daily charter hire rate, which is generally payable in advance. A time charter generally provides typical warranties and owner protective restrictions. The performance obligations in a time charter are satisfied over the term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to the owner of the vessel. The time charter contracts are considered operating leases because (i) the vessel is an identifiable asset (ii) the owner of the vessel does not have substantive substitution rights and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use. Revenues from time charters are recognized ratably on a straight-line basis over the period of the respective charter. Under time charter agreements, all voyage expenses, except commissions are assumed by the charterer. Operating costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance and lubricants are paid by the Partnership under time charter agreements. Voyage charters contracts A voyage charter is a contract in which the vessel owner undertakes to transport a specific amount and type of cargo on a load port-to-discharge port basis, subject to various cargo handling terms. The Partnership accounts for a voyage charter when all the following criteria are met: (1) the parties to the contract have approved the contract in the form of a written charter agreement and are committed to perform their respective obligations, (2) the Partnership can identify each party’s rights regarding the services to be transferred, (3) the Partnership can identify the payment terms for the services to be transferred, (4) the charter agreement has commercial substance (that is, the risk, timing, or amount of the Partnership’s future cash flows is expected to change as a result of the contract) and (5) it is probable that the Partnership will collect substantially all of the consideration to which it will be entitled in exchange for the services that will be transferred to the charterer. The Partnership determined that its voyage charters consist of a single performance obligation which is met evenly as the voyage progresses and begin to be satisfied once the vessel is ready to load the cargo. The voyage charter party agreement generally has a demurrage/dispatch clause according to which in the case of demurrage, the charterer reimburses the vessel owner for any potential delays exceeding the allowed lay time as per the charter party clause at the ports visited which is recorded as demurrage revenue. In the case of dispatch, the owner reimburses the charterer for the earlier discharging of the cargo from the agreed time. Demurrage/dispatch revenues are recognized starting from the point that is determined that the amount can be estimated, and its collection/payment is probable and on a straight-line basis until the end of the voyage. Revenues from voyage charters are recognized on a straight-line basis over the voyage duration which commences once the vessel is ready to load the cargo and terminates upon the completion of the discharge of the cargo. Under Accounting Standards Codification (“ASC”) 606, receivables represent an entity’s unconditional right to consideration, whether billed or unbilled In voyage charters, vessel operating, and voyage expenses are paid for by the Partnership. The voyage charters are considered service contracts which fall under the provisions of ASC 606 because the Partnership retains control over the operations of the vessels such as the routes taken or the vessels’ speed. Payment terms under voyage charters are disclosed in the relevant voyage charter agreements and generally have standard payment terms of 90% to 95% of the freight which is paid within three days after the completion of the vessel’s loading. 2. Significant Accounting Policies – Continued (c) Accounting for Revenue, Voyage and Operating Expenses - Continued: Vessel voyage expenses are direct expenses to voyage revenues and primarily consist of brokerage commissions, port expenses, canal dues and bunkers. Brokerage commissions are paid to shipbrokers for their time and efforts for negotiating and arranging charter party agreements on behalf of the Partnership and are expensed over the related charter period. All other voyage expenses are expensed as incurred, except for expenses during the ballast portion of the voyage (period between the contract date and the date of the vessel’s arrival to the load port). Any expenses incurred during the ballast portion of the voyage such as bunker expenses, canal tolls and port expenses are deferred and are recognized on a straight-line basis, in voyage expenses, over the voyage duration as the Partnership satisfies the performance obligations under the contract provided these costs are (1) incurred to fulfill a contract that we can specifically identify, (2) able to generate or enhance resources of the company that will be used to satisfy performance of the terms of the contract, and (3) expected to be recovered from the charterer. These costs are considered ‘contract fulfillment costs’ and are included in ‘prepayments and other assets’ in the consolidated balance sheets. Vessel operating expenses presented in the consolidated financial statements mainly consist of management fees payable to the Partnership’s managers and crew, repairs and maintenance, insurance, stores, spares, lubricants, and other operating expenses. Vessel operating expenses are expensed as incurred.

If a plan to sell a vessel is cancelled, the Partnership reclassifies the vessel as held for use and re-measures it at the lower of (i) its carrying amount before the vessel was classified as held for sale, adjusted for any depreciation expense that would have been recognized if the vessel had been continuously classified as held and used and (ii) its fair value at the date of the subsequent decision not to sell. 2.

Recent Accounting Pronouncements	(s) Recent Accounting Pronouncements On January 7, 2021, The Financial Accounting Standards Board issued the Accounting Standards Update (“ASU”) No. 2021-01—Reference Rate Reform (Topic 848). The amendments in this Update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments in this Update to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. This ASU is effective for adoption at any time between January 7, 2021 and December 31, 2022. The Partnership is currently evaluating the impact of this adoption in its consolidated financial statements and related disclosures.
