Summary Of Major Accounting Pol

Summary Of Major Accounting Policies	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
Consolidation, Variable Interest Entity, Policy	Consolidated Variable Interest Entity. We hold a 45% interest in one variable interest entity (“VIE”) located in Angola. The remaining 55% noncontrolling interest is held by a service and logistics provider located in Angola. We are the primary beneficiary and wholly consolidate the VIE as we have the power to direct the activities that most significantly affect the VIE’s economic performance and have the obligation to absorb the VIE’s losses or the right to receive benefits at 100%.
Summary Of Major Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation. The consolidated financial statements include the accounts of Oceaneering International, Inc. (“Oceaneering,” “we,” “us” or “our”) and our more than 50% owned and controlled subsidiaries. We also consolidate entities that are determined to be variable interest entities if we determine that we are the primary beneficiary; otherwise, we account for those entities using the equity method of accounting. We use the equity method to account for our investments in unconsolidated affiliated companies of which we own an equity interest of between 20% and 50% and as to which we have significant influence, but not control, over operations. We use the cost method for all other long-term investments. Investments in entities that we do not consolidate are reflected on our balance sheet in other non-current assets. All significant intercompany accounts and transactions have been eliminated. Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Reclassifications. Certain amounts from prior periods have been reclassified to conform with the current year presentation. Cash and Cash Equivalents. Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less from the date of investment. Allowance for Credit Losses—Financial Assets Measured at Amortized Costs. We identify our allowance for credit losses based on future expected losses when accounts receivable, contract assets or held-to-maturity loan receivables are created rather than when losses are probable. We use the loss-rate method in developing the allowance for credit losses, which involves identifying pools of assets with similar risk characteristics, reviewing historical losses within the last three years and consideration of reasonable supportable forecasts of economic indicators. Changes in estimates, developing trends and other new information could have material effects on future evaluations. We monitor the credit quality of our accounts receivable and other financing receivable amounts by frequent customer interaction, following economic and industry trends and reviewing specific customer data. Our other receivable amounts include contract assets and held-to-maturity loans receivable, which we consider to have a low risk of loss. We consider macroeconomic conditions when assessing our credit risk exposure, including any impacts from the conflicts in Russia and Ukraine and in the Middle East, volatility in the financial services industry and the oil and natural gas markets, and the effects thereof on our customers and various counterparties. We have determined the impacts to our credit loss expense are de minimis for the years ended December 31, 2024, 2023 and 2022. As of December 31, 2024, our allowance for credit losses was $1.5 million for accounts receivable and $1.4 million for other receivables. As of December 31, 2023, our allowance for credit losses was $2.2 million for accounts receivable and $0.6 million for other receivables. Our allowance for credit losses as of December 31, 2024 decreased when compared to the balance as of December 31, 2023, primarily due to a corresponding decrease in accounts receivable partially offset by an increase in contract assets. Financial assets are written off when deemed uncollectible and there is no reasonable expectation of recovering the contractual cash flows. During the years ended December 31, 2024, 2023 and 2022, we recognized credit losses of $0.1 million, $1.3 million and $0.4 million, respectively. We have elected to apply the practical expedient available under Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments—Credit Losses (Topic 326: Measurement of Credit Losses on Financial Instruments,” as amended (“ ASC 326”) to exclude the accrued interest receivable balance that is included in our held-to-maturity loans receivable. The amounts excluded as of December 31, 2024 and 2023 were less than $0.1 million and $0.2 million, respectively. Accounts receivable are considered to be past-due after the end of the contractual terms agreed to with the customer. There were no material past-due amounts that we consider uncollectible for our financial assets as of December 31, 2024. We generally do not require collateral from our customers. Inventory. Inventory is valued at the lower of cost or net realizable value. We determine cost using the weighted-average method. We periodically review the value of items in inventory and record write-downs or write-offs of inventory based on our assessment of market conditions. Write-downs and write-offs are charged to cost of services and products. We did not record any write-downs or write-offs of inventory in the years ended December 31, 2024, 2023 or 2022. Our inventory reserve was $36 million and $40 million as of December 31, 2024 and 2023, respectively. Business Acquisitions. We account for business combinations using the acquisition method of accounting, with acquisition prices being allocated to the assets acquired and liabilities assumed based on their fair values at the respective dates of acquisition. In October 2024, we acquired Global Design Innovation Ltd. (“GDi”), a United Kingdom (“U.K.”)-based provider of digital and software services, for approximately $33 million, including a holdback liability of $4.6 million that we recorded in accrued liabilities and other long-term liabilities on our consolidated balance sheets. We acquired cash of $1.0 million from GDi as part of this acquisition. GDi is a U.K.-based provider of asset management, engineering and software services. As the only provider certified by the U.K. Accreditation Service to perform remote visual inspection using point cloud data and photographic images, GDi brings advanced algorithms and data solutions that, when combined with Oceaneering’s engineering expertise, will strengthen Oceaneering’s ability to optimize asset management for customers in industries including oil and gas, utilities, and power generation. GDi’s suite of solutions, including its Vision software, complements Oceaneering’s portfolio by supporting enhanced safety, data quality and integrity, and cost efficiency for customers worldwide. We have accounted for this acquisition by allocating the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. As part of this acquisition, we have recorded goodwill for $16 million and intangible assets relating primarily to GDi’s software and trade name for $17 million to be amortized over their useful lives of 5 years. GDi’s operating results are included in our IMDS segment, and its activity subsequent to the date of acquisition was not significant. Property and Equipment, Long-Lived Intangible Assets and Right-of-Use Operating Lease Assets. We provide for depreciation of property and equipment on the straight-line method over estimated useful lives of eight years for Remotely Operated Vehicles (“ROVs”), three to 25 years for marine services equipment (such as vessels and diving equipment) and three to 25 years for buildings, improvements and other equipment. We charge the costs of repair and maintenance of property and equipment to operations as incurred, and we capitalize the costs of improvements that extend asset lives or functionality. Upon the disposition of property and equipment, the related cost and accumulated depreciation accounts are relieved and any resulting gain or loss is recognized in income. We capitalize interest on assets where the construction period is anticipated to be more than three months. We did not capitalize interest in 2024, 2023 or 2022. We do not allocate general and administrative costs to capital projects. We had construction in progress of $60 million and $55 million as of December 31, 2024 and 2023, respectively, primarily related to projects in our Subsea Robotics segment. Long-lived intangible assets, primarily acquired in connection with business combinations, include trade names, intellectual property and customer relationships and are being amortized over their respective estimated useful lives. Our management periodically, and upon the occurrence of a triggering event, reviews the realizability of our property and equipment, long-lived intangible assets and right-of-use operating lease assets to determine whether any events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. For long-lived assets to be held and used, we base our evaluation on impairment indicators such as the nature of the assets, the future economic benefits of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether an impairment has occurred using an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. We did not identify indicators of impairment for property and equipment, long-lived intangible assets or right-of-use operating lease assets for the years ended December 31, 2024, 2023 and 2022. For assets held for sale or disposal, the fair value of the asset is measured using fair market value less estimated costs to sell. Assets are classified as held-for-sale when we have a plan for disposal of certain assets and those assets meet the held for sale criteria. For additional information regarding right-of-use operating lease assets, see “Leases” below. Goodwill. Our goodwill is evaluated for impairment annually and whenever we identify certain triggering events or circumstances that would more likely than not reduce the fair value of a reporting unit below its carrying amount. In our annual evaluation of goodwill, we perform a qualitative or quantitative impairment test. Under the qualitative approach, if we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we are required to perform the quantitative analysis to determine the fair value of the reporting unit. We then compare the fair value of the reporting unit with its carrying amount and recognize an impairment loss for the amount by which the carrying amount exceeds the fair value of the reporting unit. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. We also consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. During the fourth quarters of 2024 and 2023, we performed our annual goodwill impairment assessment using qualitative tests that did not indicate a more detailed quantitative analysis was necessary. No goodwill impairment was recognized for the years ended December 31, 2024, 2023 and 2022. Revenue Recognition. All of our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically, ranging from weekly to monthly. We use the input method to recognize revenue, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. When appropriate, we apply the practical expedient to recognize revenue for the amount invoiced when the invoice corresponds directly to the value of our performance to date. We account for significant fixed-price contracts, mainly relating to our Manufactured Products segment, and to a lesser extent in our Offshore Projects Group (“OPG”) and Aerospace and Defense Technologies (“ADTech”) segments, by recognizing revenue over time using the cost-to-cost input method. The performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. In 2024, 2023 and 2022, we accounted for 19%, 19% and 15%, respectively, of our revenue using the cost-to-cost input method to measure progress toward satisfying the related performance obligations on our contracts. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation. We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, and that are collected by us from customers, are excluded from revenue. In our service-based business lines, we principally charge on a dayrate basis for services provided. In our product-based business lines, predominantly in our Manufactured Products segment, we recognize revenue and profit using the percentage-of-completion method and exclude uninstalled materials and significant inefficiencies from the measure of progress. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, we apply judgment, when applicable, in the determination and allocation of transaction price to performance obligations and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, when required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. During the year ended December 31, 2024, we recognized projected losses of $13 million for contracts in our Manufactured Products segment. During the year ended December 31, 2023, we recognized a projected loss of $9.8 million for contracts in our Manufactured Products segment. During the year ended December 31, 2022, we recognized a projected loss of $5.2 million for contracts in our Manufactured Products segment. There could be adjustments to overall contract costs in the future, due to changes in facts and circumstances. In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms. See Note 3 —“ Revenue” for more information on our revenue from contracts with customers. Leases. We determine whether a contract is or contains a lease at inception, whether as a lessee or a lessor. We take into consideration the elements of an identified asset, right to control and the receipt of economic benefit in making those determinations. As a lessor, we lease certain types of equipment along with the provision of services and utilize the expedient allowing us to combine the lease and non-lease components into a combined component that is accounted for (1) under the accounting standard “ Leases ” (“ASC 842”), when the lease component is predominant, and (2) under the accounting standard “ Revenue from Contracts with Customers ” (“ASC 606”), when the service component is predominant. In general, when we have a service component, it is typically the predominant element and leads to accounting under ASC 606. As a lessor, we lease certain types of equipment, often providing services at the same time. These leases can be priced on a dayrate or lump-sum basis for periods ranging from a few days to multi-year contracts. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our customer's discretion. These leases generally do not contain options to purchase, material restrictions or covenants that impact our accounting for leases. As a lessee, we lease land, buildings, vessels and equipment for the operation of our business and to support some of our service line revenue streams. These generally carry lease terms that range from days for operational and support equipment to 20 years for land and buildings. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our discretion. When the exercise of those options is reasonably certain, we include them in the lease assessment. Our leases do not contain material restrictions or covenants that impact our accounting for them, nor do we provide residual value guarantees. As a lessee, we utilize the practical expedients to not recognize leases with an initial lease term of 12 months or less on the balance sheet and to combine lease and non-lease components together and account for the combined component as a lease for all asset classes, except real estate. Right-of-use operating lease assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement or modification date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, based on the information available at commencement or modification date in determining the present value of future payments. In determining the incremental borrowing rate, we considered our external credit ratings, bond yields for us and our identified peers, the risk-free rate in geographic regions where we operate and the impact associated with providing collateral over a similar term as the lease for an amount equal to the future lease payments. Our right-of-use operating lease assets also include any lease prepayments made and exclude lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease. These options are included in the lease term when it is reasonably certain we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. See Note 4—“Leases” for more information on our operating leases. Stock-Based Compensation. We recognize all share-based payments to directors, officers and employees over their vesting periods in the income statement based on their estimated fair values. For more information on our employee benefit plans, see Note 11—“Employee Benefit Plans.” Income Taxes. We provide income taxes at appropriate tax rates in accordance with our interpretation of the respective tax laws and regulations after review and consultation with our internal tax department, tax advisors and, in some cases, legal counsel in various jurisdictions. We provide for deferred income taxes for differences between carrying amounts of assets and liabilities for financial and tax reporting purposes and provide a valuation allowance against deferred tax assets when it is more likely than not that the asset will not be realized. We recognize an expense or benefit for an uncertain tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the uncertain tax position is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement. We account for any applicable interest and penalties on these uncertain tax positions as a component of our provision for income taxes on our financial statements. We have elected to account for U.S. federal income tax on global intangible low‑taxed income (“GILTI”) as a current period expense when incurred. For more information on income taxes, see Note 6—“Income Taxes.” Foreign Currency Translation. The functional currency for most of our foreign subsidiaries is the applicable local currency. Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated into U.S. dollars using the exchange rates in effect as of the balance sheet date, and the resulting translation adjustments are recognized, net of tax, in accumulated other comprehensive income (loss) as a component of shareholders' equity. All foreign currency transaction gains and losses are recognized currently in the consolidated statements of operations. We recorded $0.9 million, $(1.4) million and less than $(0.1) million of foreign currency transaction gains (losses) in the years ended December 31, 2024, 2023 and 2022, respectively. Those amounts are included as a component of other income (expense), net in our consolidated statements of operations. Earnings (Loss) per Share. For each year presented, the only difference between our annual calculated weighted-average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units. Repurchase Plan. In December 2014, our Board of Directors approved a plan to repurchase up to 10 million shares of our common stock. Under the program, which has no expiration date, we had repurchased 2.0 million shares of our common stock for $100 million through December 2015. In the year ended December 31, 2024, we repurchased 0.8 million shares for approximately $20 million. The timing and amount of any future repurchases will be determined by our management. As of December 31, 2024, we retained 10 million of the shares we had repurchased through this and a prior repurchase program. We expect to hold the shares repurchased and any additional shares repurchased under the plan as treasury stock for possible future use. We are not obligated to make any future repurchases. We account for the shares we hold in treasury under the cost method, at average cost. Financial Instruments.
Property, Plant, and Equipment and Intangible Assets	Property and Equipment, Long-Lived Intangible Assets and Right-of-Use Operating Lease Assets. We provide for depreciation of property and equipment on the straight-line method over estimated useful lives of eight years for Remotely Operated Vehicles (“ROVs”), three to 25 years for marine services equipment (such as vessels and diving equipment) and three to 25 years for buildings, improvements and other equipment. We charge the costs of repair and maintenance of property and equipment to operations as incurred, and we capitalize the costs of improvements that extend asset lives or functionality. Upon the disposition of property and equipment, the related cost and accumulated depreciation accounts are relieved and any resulting gain or loss is recognized in income. We capitalize interest on assets where the construction period is anticipated to be more than three months. We did not capitalize interest in 2024, 2023 or 2022. We do not allocate general and administrative costs to capital projects. We had construction in progress of $60 million and $55 million as of December 31, 2024 and 2023, respectively, primarily related to projects in our Subsea Robotics segment. Long-lived intangible assets, primarily acquired in connection with business combinations, include trade names, intellectual property and customer relationships and are being amortized over their respective estimated useful lives. Our management periodically, and upon the occurrence of a triggering event, reviews the realizability of our property and equipment, long-lived intangible assets and right-of-use operating lease assets to determine whether any events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. For long-lived assets to be held and used, we base our evaluation on impairment indicators such as the nature of the assets, the future economic benefits of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether an impairment has occurred using an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. We did not identify indicators of impairment for property and equipment, long-lived intangible assets or right-of-use operating lease assets for the years ended December 31, 2024, 2023 and 2022. For assets held for sale or disposal, the fair value of the asset is measured using fair market value less estimated costs to sell. Assets are classified as held-for-sale when we have a plan for disposal of certain assets and those assets meet the held for sale criteria. For additional information regarding right-of-use operating lease assets, see “Leases” below.
Allowance for Credit Losses	Allowance for Credit Losses—Financial Assets Measured at Amortized Costs. We identify our allowance for credit losses based on future expected losses when accounts receivable, contract assets or held-to-maturity loan receivables are created rather than when losses are probable. We use the loss-rate method in developing the allowance for credit losses, which involves identifying pools of assets with similar risk characteristics, reviewing historical losses within the last three years and consideration of reasonable supportable forecasts of economic indicators. Changes in estimates, developing trends and other new information could have material effects on future evaluations. We monitor the credit quality of our accounts receivable and other financing receivable amounts by frequent customer interaction, following economic and industry trends and reviewing specific customer data. Our other receivable amounts include contract assets and held-to-maturity loans receivable, which we consider to have a low risk of loss. We consider macroeconomic conditions when assessing our credit risk exposure, including any impacts from the conflicts in Russia and Ukraine and in the Middle East, volatility in the financial services industry and the oil and natural gas markets, and the effects thereof on our customers and various counterparties. We have determined the impacts to our credit loss expense are de minimis for the years ended December 31, 2024, 2023 and 2022. As of December 31, 2024, our allowance for credit losses was $1.5 million for accounts receivable and $1.4 million for other receivables. As of December 31, 2023, our allowance for credit losses was $2.2 million for accounts receivable and $0.6 million for other receivables. Our allowance for credit losses as of December 31, 2024 decreased when compared to the balance as of December 31, 2023, primarily due to a corresponding decrease in accounts receivable partially offset by an increase in contract assets. Financial assets are written off when deemed uncollectible and there is no reasonable expectation of recovering the contractual cash flows. During the years ended December 31, 2024, 2023 and 2022, we recognized credit losses of $0.1 million, $1.3 million and $0.4 million, respectively. We have elected to apply the practical expedient available under Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments—Credit Losses (Topic 326: Measurement of Credit Losses on Financial Instruments,” as amended (“ ASC 326”) to exclude the accrued interest receivable balance that is included in our held-to-maturity loans receivable. The amounts excluded as of December 31, 2024 and 2023 were less than $0.1 million and $0.2 million, respectively. Accounts receivable are considered to be past-due after the end of the contractual terms agreed to with the customer. There were no material past-due amounts that we consider uncollectible for our financial assets as of December 31, 2024. We generally do not require collateral from our customers.

Milestones are contractually agreed with customers and relate to significant events across the contract lives. Some milestones are achieved before revenue is recognized, resulting in a contract liability, while other milestones are achieved after revenue is recognized resulting in a contract asset. The following table provides information about contract assets and contract liabilities from contracts with customers. Year Ended December 31, (in thousands) 2024 2023 Total contract assets, beginning of period $ 234,505 $ 184,847 Revenue accrued 2,540,010 2,328,382 Amounts billed (2,499,235) (2,278,724) Total contract assets, end of period $ 275,280 $ 234,505 Total contract liabilities, beginning of period $ 164,631 $ 112,950 Deferrals of milestone payments 109,641 149,864 Recognition of revenue for goods and services (133,575) (98,183) Total contract liabilities, end of period $ 140,697 $ 164,631 Performance Obligations As of December 31, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations that were unsatisfied (or partially unsatisfied) was $454 million. In arriving at this value, we have used two expedients available to us and are not disclosing amounts in relation to performance obligations: (1) that are part of contracts with an original expected duration of one year or less; or (2) on contracts where we recognize revenue in line with the billing. Of this amount, we expect to recognize revenue of $329 million over the next 12 months, $109 million within the next 24 months, and substantially all of the remaining balance of $16 million within the next 36 months. In our Manufactured Products and ADTech segments, we have long-term contracts that extend beyond one year, and these make up the majority of the performance obligations balance reported as of December 31, 2024. We also have shorter-term product contracts with an expected original duration of one year or less that have been excluded. Where appropriate, we have made estimates within the transaction price of elements of variable consideration within the contracts and constrained those amounts to a level where we consider it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The amount of revenue recognized in the years ended December 31, 2024 and 2023 that was associated with performance obligations completed or partially completed in prior periods was not significant. As of December 31, 2024, there were no significant outstanding liability balances for refunds or returns due to the nature of our contracts and the services and products we provide. Our warranties are limited to assurance warranties that are of a standard length and are not considered to be material rights . The majority of our contracts consist of a single performance obligation. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, when there are multiple obligations, we look for observable evidence of stand-alone selling prices on which to base the allocation. Costs to Obtain or Fulfill a Contract In line with the available practical expedient, we capitalize incremental costs to obtain a contract that would not have been incurred if the contract had not been obtained when those amounts are significant and the contract is expected at inception to exceed one year in duration. Our costs to obtain a contract primarily consist of bid and proposal costs, which are generally expensed in the period when incurred. There were no balances or amortization of costs to obtain a contract in the current reporting periods. Costs to fulfill a contract primarily consist of certain mobilization costs incurred to provide services or products to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of costs to fulfill a contract was $3.2 million and $7.8 million as of December 31, 2024 and 2023, respectively. For the years ended December 31, 2024, 2023 and 2022, we recorded amortization expense of $4.9 million, $5.8 million, and $5.6 million, respectively. No impairment costs were recognized.

The carryforwards include $58 million that do not expire and $402 million that will expire from 2025 through 2044. We have recorded a total valuation allowance of $640 million on net operating loss, tax credit carryforwards, and other deferred tax assets, as we believe that it is more likely than not that a portion of our deferred tax assets will not be realized. We assess the realizability of our deferred tax assets, considering all relevant factors, at each reporting period. Based on the available positive and negative evidence, including historical and forecasted earnings, we believe it is more likely than not that deferred tax assets in several non-U.S. jurisdictions will be realized. Accordingly, during the twelve-month period ended December 31, 2024 and 2023, we partially released valuation allowances for the deferred tax assets that we believe are more likely than not to be realized. Our valuation allowance decreased by $23 million in 2024 and $21 million in 2023. During the twelve-month period ended December 31, 2023, we received refunds of $23 million, including interest of $1.7 million which was recorded as a tax benefit, under the U.S. Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). We continue to make an assertion to indefinitely reinvest the unrepatriated earnings of any foreign subsidiary that would incur material tax consequences upon the distribution of such earnings. As of December 31, 2024, we did not provide for deferred taxes on earnings of our foreign subsidiaries that are indefinitely reinvested. If we were to make a distribution from the unremitted earnings of these subsidiaries, we could be subject to taxes in various jurisdictions. However, it is not practical to estimate the amount of tax that could ultimately be due if such earnings were remitted. If our expectations were to change regarding future tax consequences, we may be required to record additional deferred taxes that could have a material effect on our consolidated financial statements. We recognize the expense or benefit for an uncertain tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the uncertain tax position is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement. We account for any applicable interest and penalties on these positions as a component of our provision for income taxes in our consolidated financial statements. A reconciliation of the beginning and ending amount of gross uncertain tax positions, excluding penalties and interest, is as follows: Year Ended December 31, (in thousands) 2024 2023 2022 Balance at beginning of year $ 25,457 $ 15,846 $ 17,367 Additions based on tax positions related to the current year 1,782 4,391 269 Reductions for expiration of statutes of limitations (505) (130) (520) Additions based on tax positions related to prior years 2,790 12,576 1,103 Reductions based on tax positions related to prior years (7,020) (135) (2,171) Settlements (3,967) (7,091) (202) Balance at end of year $ 18,537 $ 25,457 $ 15,846 We increased (decreased) income tax expense by $1.0 million, $5.4 million and $(1.0) million in 2024, 2023 and 2022, respectively, for penalties and interest on uncertain tax positions. Our total liabilities for penalties and interest on uncertain tax positions were $5.6 million and $7.9 million in other long-term liabilities on our balance sheets as of December 31, 2024 and 2023, respectively. All additions or reductions to those liabilities would affect our effective income tax rate in the periods of change. We believe approximately $8.0 million to $15 million of gross uncertain tax positions will be resolved within the next 12 months. As of December 31, 2023, a portion of our uncertain tax position liability was reflected as a reduction in our gross deferred tax asset before valuation allowance and as a reduction in our long-term income tax receivable, which was included in other noncurrent assets on our consolidated balance sheet. The remaining balance was reflected in other long-term liabilities on our consolidated balance sheet. The balance of gross uncertain tax position liability included in other long-term liabilities on our consolidated balance sheet was $19 million as of December 31, 2024 and 2023. The balance of gross uncertain tax position liability netted against our gross deferred tax asset before valuation allowance was $5.0 million as of December 31, 2023. The balance of gross uncertain tax position liability netted against our gross long-term income tax receivable included in other noncurrent assets was $1.0 million as of December 31, 2023. Our tax returns are subject to audit by taxing authorities in multiple jurisdictions. These audits often take years to complete and settle.

Debt Disclosure [Abstract]
Debt Disclosure	DEBT The carrying value of long-term debt consisted of the following: December 31, (in thousands) 2024 2023 6.000% Senior Notes due 2028 $ 500,000 $ 500,000 Unamortized discount and debt issuance costs (17,991) (22,942) Long-term Debt $ 482,009 $ 477,058 2024 Senior Notes. In November 2014, we completed the public offering of $500 million aggregate principal amount of 4.650% Senior Notes due 2024 (the “2024 Senior Notes”). We paid interest on the 2024 Senior Notes on May 15 and November 15 of each year. The 2024 Senior Notes were scheduled to mature on November 15, 2024. In the year ended December 31, 2021, we repurchased $100 million in aggregate principal amount of the 2024 Senior Notes in open-market transactions. The aggregate purchase price in the year ended December 31, 2021 included accrued and unpaid interest to the repurchase date of $0.7 million, and we recorded loss on extinguishment of debt of $1.1 million (including premiums and fees associated with the repurchases). On October 2, 2023, we repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million in the Tender Offer (as defined herein). On November 2, 2023 (the “Redemption Date”), after delivering a notice to the holders of the 2024 Senior Notes, we redeemed all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes at par, pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price was equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” 2028 Senior Notes. In February 2018, we completed the public offering of $300 million aggregate principal amount of 6.000% Senior Notes due 2028 (the “Existing 2028 Senior Notes”) and on October 2, 2023, we completed a private placement of $200 million aggregate principal amount of additional 2028 Senior Notes (the “New 2028 Senior Notes” and, together with the Existing 2028 Senior Notes, the “2028 Senior Notes”) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The New 2028 Senior Notes constituted an additional issuance of the Existing 2028 Senior Notes and form a single series with such notes. We pay interest on the 2028 Senior Notes on February 1 and August 1 of each year. The 2028 Senior Notes are scheduled to mature on February 1, 2028. The indentures governing our 2028 Senior Notes generally limit our ability to incur secured debt for borrowed money (such as borrowings under our revolving credit facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures) and contain various other covenants and events of default. We used the net proceeds from the Existing 2028 Senior Notes to repay our term loan indebtedness described further below. We may redeem some or all of the 2028 Senior Notes at specified redemption prices. We received net proceeds from the offering of the New 2028 Senior Notes of $178 million, after initial purchasers’ discounts and debt issuance costs. We used the net proceeds from the New 2028 Senior Notes, together with cash on hand, to fund the Tender Offer (as defined herein). On October 2, 2023, we used the net proceeds from the offering discussed above, together with cash on hand, to fund our offer to purchase (the “Tender Offer”) for cash any and all of the $400 million principal amount outstanding of the 2024 Senior Notes. The consummation of the Tender Offer was contingent upon the completion of the offering discussed above, which was satisfied on October 2, 2023. Revolving Credit Agreement. In October 2014, we entered into a credit agreement (as amended, the “Prior Credit Agreement”) with a group of banks. The Prior Credit Agreement initially provided for a $500 million five-year revolving credit facility (the “Prior Revolving Credit Facility”). The Prior Credit Agreement also provided for a $300 million term loan, which we repaid in full in February 2018, using net proceeds from the issuance of our Existing 2028 Senior Notes, referred to above, and cash on hand. In February 2018, we entered into Agreement and Amendment No. 4 to the Prior Credit Agreement to, among other things, extend the maturity of the Prior Revolving Credit Facility to January 25, 2023. On April 8, 2022, we entered into a new senior secured revolving credit agreement with a group of banks (as amended by an Agreement and Amendment No. 1 to Credit Agreement, dated September 20, 2023, the “Revolving Credit Agreement”). The commitments under the Revolving Credit Agreement are scheduled to mature on April 8, 2027. The Revolving Credit Agreement includes a $215 million revolving credit facility (the “Revolving Credit Facility”) with a $100 million sublimit for the issuance of letters of credit. Our obligations under the Revolving Credit Agreement are guaranteed by certain of our wholly owned subsidiaries and are secured by first priority liens on certain of our assets and those of the guarantors, including, among other things, intellectual property, inventory, accounts receivable, equipment and equity interests in subsidiaries. As of December 31, 2024 and 2023, we had no borrowings outstanding under the Revolving Credit Facility and no letters of credit outstanding under the Revolving Credit Agreement. We may borrow under the Revolving Credit Facility at either (1) a base rate, determined as the greatest of (A) the prime rate of Wells Fargo Bank, National Association, (B) the federal funds effective rate plus 1 ⁄ 2 of 1% and (C) Adjusted Term Secured Overnight Financing Rate (“SOFR”) (as defined in the Revolving Credit Agreement for a one-month tenor plus 1%, in each case plus the applicable margin, which varies from 1.25% to 2.25% depending on our Consolidated Net Leverage Ratio (as defined in the Revolving Credit Agreement), or (2) Adjusted Term SOFR plus the applicable margin, which varies from 2.25% to 3.25% depending on our Consolidated Net Leverage Ratio. We will also pay a facility fee based on the amount of the underlying commitment that is being utilized, which fee varies from 0.300% to 0.375%, with the higher rate owed when we use the Revolving Credit Facility less. The Revolving Credit Agreement includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted Consolidated Net Leverage Ratio was initially 4.00 to 1.00 and subsequently decreased to 3.25 to 1.00. As of December 31, 2024 and 2023, the maximum permitted Consolidated Net Leverage Ratio was 3.25 to 1.00 and will not change during the remaining term of the Revolving Credit Facility. The minimum Consolidated Interest Coverage Ratio (as defined in the Revolving Credit Agreement) is 3.00 to 1.00 throughout the term of the Revolving Credit Facility. Availability under the Revolving Credit Facility may be limited by these financial covenants and the requirement that any borrowing under the Revolving Credit Facility not require the granting of any liens to secure any senior notes issued by us. The indentures governing the 2028 Senior Notes, and prior to November 2, 2023, the 2024 Senior Notes, generally limit our ability to incur secured debt for borrowed money (such as borrowings under the Revolving Credit Facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures). As of December 31, 2024, the full $215 million was available to borrow under the Revolving Credit Facility. In addition, the Revolving Credit Agreement contains various covenants that we believe are customary for agreements of this nature, including, but not limited to, restrictions on our ability and the ability of each of our subsidiaries to incur debt, grant liens, make certain investments, make distributions, merge or consolidate, sell assets and enter into certain restrictive agreements. As of December 31, 2024, we were in compliance with all the covenants set forth in the Revolving Credit Agreement. Interest Rate Swaps. We had two interest rate swaps in place relating to a total of $200 million of the 2024 Senior Notes for the period to November 2024. The agreements swapped the fixed interest rate of 4.65% on $100 million of the 2024 Senior Notes to the floating rate of one-month London Interbank Offered Rate (“LIBOR”) plus 2.426% and on another $100 million to one-month LIBOR plus 2.823%. In March 2020, we settled both interest rate swaps with the counterparty for cash proceeds of $13 million. The settlement resulted in a $13 million increase to our long-term debt balance that was being amortized as a reduction to interest expense prospectively through the maturity date for the 2024 Senior Notes using the effective interest method. In the year ended December 31, 2023, we amortized $4.4 million to interest expense, including $2.7 million, for the write-off of interest rate swap settlement gains associated with the retirement of the 2024 Senior Notes discussed above. In the year ended December 31, 2022, we amortized $2.2 million to interest expense. Debt Issuance Costs, Discount and Interest. We incurred $6.9 million of issuance costs related to the 2024 Senior Notes. These costs were included as a reduction of long-term debt in our consolidated balance sheet. We were amortizing these costs to interest expense through the maturity date. In the year ended December 31, 2023, we amortized $1.3 million to interest expense, including $0.7 million, for the write-off of the debt issuance costs balance associated with the retirement of the 2024 Senior Notes discussed above. In the year ended December 31, 2022, we amortized $0.7 million to interest expense. We incurred $7.1 million of issuance costs related to the 2028 Senior Notes and $4.0 million of loan costs related to the Revolving Credit Agreement. These costs, net of accumulated amortization, are included as a reduction of long-term debt in our consolidated balance sheets, as they pertain to the 2028 Senior Notes, and in other noncurrent assets, as they pertain to the Revolving Credit Agreement. We are amortizing these costs to interest expense through the respective maturity dates for the 2028 Senior Notes and the Revolving Credit Agreement using the straight-line method, which approximates the effective interest rate method. In the years ended December 31, 2024 and 2023, we amortized $2.1 million and $1.6 million, respectively, to interest expense. We recorded a discount of $20 million related to the 2028 Senior Notes issued in October 2023. This cost, net of accumulated amortization, is included as a reduction of long-term debt in our consolidated balance sheets and is being amortized to interest expense through the maturity date of the 2028 Senior Notes using the straight-line method, which approximates the effective interest rate method. In the years ended December 31, 2024 and 2023, we amortized $4.0 million and $0.9 million, respectively, to interest expense. We made cash interest payments of $32 million, $34 million and $38 million in 2024, 2023 and 2022, respectively.

Our Aerospace and Defense Technologies segment provides services and products, including engineering and related manufacturing in defense and space exploration activities, principally to U.S. Government agencies and their prime contractors. Unallocated Expenses are those not associated with a specific business segment. These consist of expenses related to our incentive and deferred compensation plans, including restricted stock units, performance units and bonuses, as well as other general expenses, including corporate administrative expenses. Our CODM is our chief executive officer. Our CODM analyzes each segment’s performance using revenue and operating income (loss). Operating income (loss) includes certain regional shared services cost allocations directly attributable to each segment. Intersegment revenue and expenses have been eliminated in the reported revenue and operating income (loss). We determine operating income (loss) for each business segment before interest income or expense, equity in income (losses) of unconsolidated affiliates, other income (expense) and provision for income taxes. Our CODM uses both revenue and operating income (loss) for each segment in the annual budgeting and forecasting processes. The CODM considers budget-to-actual and forecast-to-actual variances on a quarterly basis when making decisions about the allocation of operating and capital resources to each segment. There are no differences in the basis of segmentation or in the basis of measurement of segment profit or loss from those used in our consolidated financial statements for the years ended December 31, 2023 and 2022. We have added additional disclosures, retrospectively, as required under ASU 2023-07. The tables that follow present information about our business segments, as well as the Unallocated Expenses category, and includes a reconciliation to income (loss) before income taxes:

Commitments And Contingencies

Commitments And Contingencies	12 Months Ended
	Dec. 31, 2024
Commitments and Contingencies Disclosure [Abstract]
Insurance Disclosure	Insurance The workers' compensation, maritime employer's liability and comprehensive general liability insurance policies that we purchase each include a deductible layer, for which we would be responsible, that we consider financially prudent. Insurance above the deductible layers can be by occurrence or in the aggregate. We determine the level of accruals for claims exposure by reviewing our historical experience and current year claim activity. We do not record accruals on a present-value basis. We review larger claims with insurance adjusters and establish specific reserves for known liabilities. We establish an additional reserve for incidents incurred but not reported to us for each year using our estimates and based on prior experience. We believe we have established adequate accruals for expected liabilities arising from those obligations. However, it is possible that future earnings could be affected by changes in our estimates relating to these matters.
Legal Matters and Contingencies	Litigation In the ordinary course of business, we are, from time to time, involved in litigation or subject to disputes, governmental investigations or claims related to our business activities, including, among other things: • performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and • workers’ compensation claims, Jones Act claims, occupational hazard claims, premises liability claims and other claims. Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, because of the inherent uncertainty of litigation and other dispute resolution proceedings and, in some cases, the availability and amount of potentially available insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs.
Contingencies Disclosure	COMMITMENTS AND CONTINGENCIES Lease Commitments As of December 31, 2024, we occupied several facilities under noncancellable operating leases expiring at various dates through 2040. See Note 4 —“ Leases” for more information on our operating leases. Insurance The workers' compensation, maritime employer's liability and comprehensive general liability insurance policies that we purchase each include a deductible layer, for which we would be responsible, that we consider financially prudent. Insurance above the deductible layers can be by occurrence or in the aggregate. We determine the level of accruals for claims exposure by reviewing our historical experience and current year claim activity. We do not record accruals on a present-value basis. We review larger claims with insurance adjusters and establish specific reserves for known liabilities. We establish an additional reserve for incidents incurred but not reported to us for each year using our estimates and based on prior experience. We believe we have established adequate accruals for expected liabilities arising from those obligations. However, it is possible that future earnings could be affected by changes in our estimates relating to these matters. Litigation In the ordinary course of business, we are, from time to time, involved in litigation or subject to disputes, governmental investigations or claims related to our business activities, including, among other things: • performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and • workers’ compensation claims, Jones Act claims, occupational hazard claims, premises liability claims and other claims. Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, because of the inherent uncertainty of litigation and other dispute resolution proceedings and, in some cases, the availability and amount of potentially available insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs. Letters of Credit We had $72 million and $62 million in letters of credit outstanding as of December 31, 2024 and 2023, respectively, which related to self-insurance requirements and various bid and performance bonds, which are usually for the duration of the applicable contract. Financial Instruments and Risk Concentration In the normal course of business, we manage risks associated with foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions. As a matter of policy, we do not use derivative instruments unless we have an underlying exposure. Other financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents and accounts receivable. The carrying values of cash and cash equivalents approximate their fair values due to the short-term maturity of the underlying instruments. Accounts receivable are generated from a broad group of customers, primarily from the energy industry and the U.S. Government, which are major sources of our revenue. Due to their short-term nature, carrying values of our accounts receivable and accounts payable approximate fair market values. We estimated the aggregate fair market value of the 2028 Senior Notes to be $494 million as of December 31, 2024 based on quoted prices. Since the market for the 2028 Senior Notes is not an active market, the fair value of the 2028 Senior Notes is classified within Level 2 in the fair value hierarchy under U.S. GAAP (inputs other than quoted prices in active markets for similar assets and liabilities that are observable or can be corroborated by observable market data for substantially the full terms for the assets or liabilities). Foreign currency gains (losses) were $0.9 million, $(1.4) million and less than $(0.1) million in the years ended December 31, 2024, 2023 and 2022, respectively. We recorded foreign currency transaction gains (losses) as a component of other income (expense), net in our consolidated statements of operations in those respective periods. Any conversion of cash balances in deposit accounts in Angola from kwanza to U.S. dollars is controlled by the central bank in Angola. As of December 31, 2024 and 2023, we had the equivalent of approximately $19 million and $8.1 million of kwanza cash balances, respectively, in Angola reflected on our consolidated balance sheets. To mitigate our currency exposure risk in Angola, we have used kwanza to purchase equivalent Angolan central bank (Banco Nacional de Angola) bonds. These bonds are denominated as U.S. dollar equivalents, so that, upon payment of semi-annual interest and principal upon maturity, payment will be settled and made in kwanza, equivalent to the respective U.S. dollars at the then-current exchange rate. In the third quarter of 2024, we purchased $7.0 million of U.S. dollar equivalent Angolan bonds. These bonds mature in February 2031. Because we intend to sell the bonds if we are able to repatriate the proceeds, we have classified these bonds as available-for-sale securities, and they are recorded at fair market value in other current assets in our consolidated balance sheet as of December 31, 2024. We did not sell any of our Angolan bonds in the year ended December 31, 2024. We estimated the fair market value of the Angolan bonds to be $7.0 million as of December 31, 2024, using quoted market prices. Since the market for the Angolan bonds was not an active market, the fair value of the Angolan bonds was classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of December 31, 2022, we had $6.2 million of U.S. dollar equivalent Angolan bonds that were classified as available-for-sale securities and recorded at fair market value in other current assets in our consolidated balance sheets. These bonds matured on September 1, 2023, and we received cash proceeds of kwanza equivalent to $6.2 million in U.S. dollars. In the three-month period ended June 30, 2021, we were notified by a customer in our Manufactured Products segment that it was suspending a contract that was substantially complete. Specific to this contract, we billed and received $12 million in the year ended December 31, 2024. As of December 31, 2024, we had outstanding contract assets of approximately $1.3 million for the contract and contract liabilities of $2.2 million prepaid for storage of components. As of December 31, 2023, we had outstanding contract assets of approximately $1.3 million for the contract and contract liabilities of $3.4 million prepaid for storage of components. We are in discussions with the customer concerning the timing of remaining payments. We continue to believe we will realize these contract assets at their book values, although we can provide no assurance as to the timing of receipt of the remaining payments.

Employee Benefit Plans and Shareholder Rights Plan [Abstract]
Employee Benefit Plans and Shareholder Rights Plan	EMPLOYEE BENEFIT PLANS Retirement Investment Plans We have several employee retirement investment plans that, taken together, cover most of our full-time employees. The Oceaneering Retirement Investment Plan is a 401(k) plan in which U.S. employees may participate by deferring a portion of their gross monthly salary and directing us to contribute the deferred amount to the plan. We match a portion of the employees' deferred compensation. Our contributions to the 401(k) plan were $24 million, $23 million and $20 million for the plan years ended December 31, 2024, 2023 and 2022, respectively. We also make matching contributions to foreign employee savings plans similar in nature to a 401(k) plan. In 2024, 2023 and 2022, these contributions, principally related to plans associated with the United Kingdom and Norwegian subsidiaries, were $14 million, $12 million and $11 million, respectively. The Oceaneering International, Inc. Supplemental Executive Retirement Plan covers selected key management employees and executives, as approved by the Compensation Committee of our Board of Directors (the “Compensation Committee”). Under this plan, we accrue an amount determined as a percentage of the participant's gross monthly salary and the amounts accrued are treated as if they are invested in one or more investment vehicles pursuant to this plan. Net expenses related to this plan during 2024, 2023 and 2022 were $1.9 million, $1.3 million and $2.6 million, respectively. Incentive Plans Under our Second Amended and Restated 2010 Incentive Plan and our 2020 Incentive Plan (together the “Incentive Plans”), shares of our common stock are made available for awards to employees and nonemployee members of our Board of Directors. The Incentive Plans are administered primarily by the Compensation Committee; however, the full Board of Directors makes determinations regarding awards to nonemployee directors under the Incentive Plans. The Compensation Committee or our Board of Directors, as applicable, determines the type(s) of award(s) to be made to each participant and sets forth in the related award agreement the terms, conditions and limitations applicable to each award. Stock options, stock appreciation rights and stock and cash awards may be made under the Incentive Plans. There are no options outstanding under either Incentive Plan. We have not granted any stock options since 2005 and the Compensation Committee has expressed its intention to refrain from using stock options as a component of employee compensation for our executive officers and other employees for the foreseeable future. Additionally, the Board of Directors has expressed its intention to refrain from using stock options as a component of nonemployee director compensation for the foreseeable future. In 2024, 2023 and 2022, the Compensation Committee granted awards of performance units to certain of our key executives and employees. The performance units awarded are scheduled to vest in full on the third anniversary of the applicable award dates, or pro rata over three years if the participant meets certain age and years of service requirements. The Compensation Committee and the Board of Directors approved specific financial goals and measures (as defined), for each of the three Annually, the Compensation Committee of our Board of Directors grants restricted units of our common stock to certain of our key executives and employees and restricted common stock to our nonemployee directors. Over 78%, 80% and 83% of the grants made to our employees in 2024, 2023 and 2022, respectively, vest in full on the third anniversary of the award date, conditional upon continued employment through such vesting date. The remainder of the grants made to employees can vest pro rata over three years, provided the individual meets certain age and years-of-service requirements. For the grants of restricted stock units to each of the participant employees, the participant will be issued one share of our common stock for each of the participant's vested restricted stock units at the earlier of three years or, if the participant vested earlier after meeting the age and service requirements, following termination of employment or service; however, the restricted stock units outstanding have no voting or dividend rights. The grants of restricted stock to our nonemployee directors generally vest in full on the first anniversary of the award date, conditional upon continued service as a director, except for the 2023 grant to one director who retired from our board of directors as of the date of our annual meeting in May 2023, which vested on that date. Each grantee of shares of restricted stock to our nonemployee directors is deemed to be the record owner of those shares during the restriction period, with the right to vote and receive any dividends on those shares. The Compensation Committee has a policy that Oceaneering will not provide U.S. federal income tax gross-up payments to any of its directors or executive officers in connection with future awards of restricted stock or stock units. The additional tax charge(benefit) realized from tax deductions less than or in excess of the financial statement expense of our restricted stock grants was $(2.0) million, $(1.4) million and $0.1 million in 2024, 2023 and 2022, respectively. The 2024, 2023 and 2022 charges were recognized in our consolidated statements of operations. The following is a summary of our restricted stock and restricted stock unit activity for 2024, 2023 and 2022: Number Weighted Average Fair Value Aggregate Intrinsic Value Balance as of December 31, 2021 2,447,259 $ 12.10 Granted 898,264 14.14 Issued (674,968) 14.53 $ 9,529,000 Forfeited (134,748) 12.19 Balance as of December 31, 2022 2,535,807 $ 12.18 Granted 753,670 19.14 Issued (823,785) 10.95 $ 16,232,000 Forfeited (180,382) 13.82 Balance as of December 31, 2023 2,285,310 $ 14.78 Granted 763,180 21.97 Issued (982,390) 12.32 $ 21,616,000 Forfeited (60,498) 18.29 Balance as of December 31, 2024 2,005,602 $ 18.62 Grants of restricted stock units are valued at their estimated fair values as of their respective grant dates. The grants in 2024, 2023 and 2022 were subject only to vesting conditioned on continued employment or service as a nonemployee director; therefore, these grants were valued at the grant date fair market value using the closing price of our stock on the New York Stock Exchange. Compensation expense under the restricted stock plans was $12 million, $11 million and $9.6 million for 2024, 2023 and 2022, respectively. As of December 31, 2024, we had $13 million of future expense to be recognized related to our restricted stock unit plans over a weighted-average remaining life of 1.7 years. Post-Employment Benefit Pursuant to a service agreement we entered into with a former Chairman of the Board of Directors, we are obligated to provide for medical coverage on an after-tax basis to him, his spouse and two adult children for their lives. Our total accrued liabilities, current and long-term, under this post-employment benefit were $1.8 million as of both December 31, 2024 and 2023.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	2. ACCOUNTING STANDARDS UPDATE Recently Adopted Accounting Standards. In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“Topic 280”), which requires enhanced disclosures about significant segment expenses. Under Topic 280, companies are required to disclose, on an annual and interim basis, any significant segment expense that is regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss. The title and position of the CODM must be disclosed plus an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Our adoption of Topic 280 for the fiscal year ended December 31, 2024, and its retrospective application to all prior periods presented in our financial statements did not have a material impact on our disclosures. For more information on our segment disclosures, see Note 10—“Operations by Business Segment and Geographic Area.” Recently Issued Accounting Standards. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“Topic 740”), which applies to all entities subject to income taxes. Topic 740 requires disaggregated information about a reporting entity’s effective tax rate reconciliation, including percentages and amounts, as well as information on income taxes paid, net of refunds disaggregated by federal, state, local and foreign and by jurisdiction if the amount is 5% or more of total income tax payments, net of refunds. Topic 740 is effective for annual periods beginning after December 15, 2024. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. We anticipate that Topic 740 will only impact our disclosures and therefore do not expect that Topic 740 will have a material impact on our consolidated financial statements.

Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition. All of our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically, ranging from weekly to monthly. We use the input method to recognize revenue, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. When appropriate, we apply the practical expedient to recognize revenue for the amount invoiced when the invoice corresponds directly to the value of our performance to date. We account for significant fixed-price contracts, mainly relating to our Manufactured Products segment, and to a lesser extent in our Offshore Projects Group (“OPG”) and Aerospace and Defense Technologies (“ADTech”) segments, by recognizing revenue over time using the cost-to-cost input method. The performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. In 2024, 2023 and 2022, we accounted for 19%, 19% and 15%, respectively, of our revenue using the cost-to-cost input method to measure progress toward satisfying the related performance obligations on our contracts. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation. We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, and that are collected by us from customers, are excluded from revenue. In our service-based business lines, we principally charge on a dayrate basis for services provided. In our product-based business lines, predominantly in our Manufactured Products segment, we recognize revenue and profit using the percentage-of-completion method and exclude uninstalled materials and significant inefficiencies from the measure of progress. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, we apply judgment, when applicable, in the determination and allocation of transaction price to performance obligations and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, when required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. During the year ended December 31, 2024, we recognized projected losses of $13 million for contracts in our Manufactured Products segment. During the year ended December 31, 2023, we recognized a projected loss of $9.8 million for contracts in our Manufactured Products segment. During the year ended December 31, 2022, we recognized a projected loss of $5.2 million for contracts in our Manufactured Products segment. There could be adjustments to overall contract costs in the future, due to changes in facts and circumstances. In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms. See Note 3 —“ Revenue” for more information on our revenue from contracts with customers.

Business Combinations and Other Purchase of Business Transactions, Policy [Policy Text Block]	Business Acquisitions. We account for business combinations using the acquisition method of accounting, with acquisition prices being allocated to the assets acquired and liabilities assumed based on their fair values at the respective dates of acquisition. In October 2024, we acquired Global Design Innovation Ltd. (“GDi”), a United Kingdom (“U.K.”)-based provider of digital and software services, for approximately $33 million, including a holdback liability of $4.6 million that we recorded in accrued liabilities and other long-term liabilities on our consolidated balance sheets. We acquired cash of $1.0 million from GDi as part of this acquisition. GDi is a U.K.-based provider of asset management, engineering and software services. As the only provider certified by the U.K. Accreditation Service to perform remote visual inspection using point cloud data and photographic images, GDi brings advanced algorithms and data solutions that, when combined with Oceaneering’s engineering expertise, will strengthen Oceaneering’s ability to optimize asset management for customers in industries including oil and gas, utilities, and power generation. GDi’s suite of solutions, including its Vision software, complements Oceaneering’s portfolio by supporting enhanced safety, data quality and integrity, and cost efficiency for customers worldwide. We have accounted for this acquisition by allocating the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. As part of this acquisition, we have recorded goodwill for $16 million and intangible assets relating primarily to GDi’s software and trade name for $17 million to be amortized over their useful lives of 5 years. GDi’s operating results are included in our IMDS segment, and its activity subsequent to the date of acquisition was not significant.

Summary Of Major Accounting _11

Summary Of Major Accounting Policies (Details)	12 Months Ended
	Dec. 31, 2024
Disposition [Line Items]
Subsidiary or Equity Method Investee, Cumulative Percentage Ownership after All Transactions	50%
Treasury Stock [Text Block]	Repurchase Plan.
Principles of Consolidation	Principles of Consolidation. The consolidated financial statements include the accounts of Oceaneering International, Inc. (“Oceaneering,” “we,” “us” or “our”) and our more than 50% owned and controlled subsidiaries. We also consolidate entities that are determined to be variable interest entities if we determine that we are the primary beneficiary; otherwise, we account for those entities using the equity method of accounting. We use the equity method to account for our investments in unconsolidated affiliated companies of which we own an equity interest of between 20% and 50% and as to which we have significant influence, but not control, over operations. We use the cost method for all other long-term investments. Investments in entities that we do not consolidate are reflected on our balance sheet in other non-current assets. All significant intercompany accounts and transactions have been eliminated.
Use Of Estimates	Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less from the date of investment.
Inventory	Inventory. Inventory is valued at the lower of cost or net realizable value. We determine cost using the weighted-average method. We periodically review the value of items in inventory and record write-downs or write-offs of inventory based on our assessment of market conditions. Write-downs and write-offs are charged to cost of services and products. We did not record any write-downs or write-offs of inventory in the years ended December 31, 2024, 2023 or 2022. Our inventory reserve was $36 million and $40 million as of December 31, 2024 and 2023, respectively.
Business Acquisitions	Business Acquisitions. We account for business combinations using the acquisition method of accounting, with acquisition prices being allocated to the assets acquired and liabilities assumed based on their fair values at the respective dates of acquisition. In October 2024, we acquired Global Design Innovation Ltd. (“GDi”), a United Kingdom (“U.K.”)-based provider of digital and software services, for approximately $33 million, including a holdback liability of $4.6 million that we recorded in accrued liabilities and other long-term liabilities on our consolidated balance sheets. We acquired cash of $1.0 million from GDi as part of this acquisition. GDi is a U.K.-based provider of asset management, engineering and software services. As the only provider certified by the U.K. Accreditation Service to perform remote visual inspection using point cloud data and photographic images, GDi brings advanced algorithms and data solutions that, when combined with Oceaneering’s engineering expertise, will strengthen Oceaneering’s ability to optimize asset management for customers in industries including oil and gas, utilities, and power generation. GDi’s suite of solutions, including its Vision software, complements Oceaneering’s portfolio by supporting enhanced safety, data quality and integrity, and cost efficiency for customers worldwide. We have accounted for this acquisition by allocating the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. As part of this acquisition, we have recorded goodwill for $16 million and intangible assets relating primarily to GDi’s software and trade name for $17 million to be amortized over their useful lives of 5 years. GDi’s operating results are included in our IMDS segment, and its activity subsequent to the date of acquisition was not significant.
Revenue Recognition	Revenue Recognition. All of our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically, ranging from weekly to monthly. We use the input method to recognize revenue, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. When appropriate, we apply the practical expedient to recognize revenue for the amount invoiced when the invoice corresponds directly to the value of our performance to date. We account for significant fixed-price contracts, mainly relating to our Manufactured Products segment, and to a lesser extent in our Offshore Projects Group (“OPG”) and Aerospace and Defense Technologies (“ADTech”) segments, by recognizing revenue over time using the cost-to-cost input method. The performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. In 2024, 2023 and 2022, we accounted for 19%, 19% and 15%, respectively, of our revenue using the cost-to-cost input method to measure progress toward satisfying the related performance obligations on our contracts. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation. We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, and that are collected by us from customers, are excluded from revenue. In our service-based business lines, we principally charge on a dayrate basis for services provided. In our product-based business lines, predominantly in our Manufactured Products segment, we recognize revenue and profit using the percentage-of-completion method and exclude uninstalled materials and significant inefficiencies from the measure of progress. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, we apply judgment, when applicable, in the determination and allocation of transaction price to performance obligations and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, when required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. During the year ended December 31, 2024, we recognized projected losses of $13 million for contracts in our Manufactured Products segment. During the year ended December 31, 2023, we recognized a projected loss of $9.8 million for contracts in our Manufactured Products segment. During the year ended December 31, 2022, we recognized a projected loss of $5.2 million for contracts in our Manufactured Products segment. There could be adjustments to overall contract costs in the future, due to changes in facts and circumstances. In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms. See Note 3 —“ Revenue” for more information on our revenue from contracts with customers.
Stock-based Compensation	Stock-Based Compensation. We recognize all share-based payments to directors, officers and employees over their vesting periods in the income statement based on their estimated fair values. For more information on our employee benefit plans, see Note 11—“Employee Benefit Plans.”
Income Taxes	Income Taxes. We provide income taxes at appropriate tax rates in accordance with our interpretation of the respective tax laws and regulations after review and consultation with our internal tax department, tax advisors and, in some cases, legal counsel in various jurisdictions. We provide for deferred income taxes for differences between carrying amounts of assets and liabilities for financial and tax reporting purposes and provide a valuation allowance against deferred tax assets when it is more likely than not that the asset will not be realized. We recognize an expense or benefit for an uncertain tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the uncertain tax position is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement. We account for any applicable interest and penalties on these uncertain tax positions as a component of our provision for income taxes on our financial statements. We have elected to account for U.S. federal income tax on global intangible low‑taxed income (“GILTI”) as a current period expense when incurred. For more information on income taxes, see Note 6—“Income Taxes.”
Foreign Currency Translations	Foreign Currency Translation.
Derivatives, Policy [Policy Text Block]	Financial Instruments. We recognize all derivative instruments as either assets or liabilities in the balance sheet and measure those instruments at fair value. Subsequent changes in fair value are reflected in current earnings or other comprehensive income (loss), depending on whether a derivative instrument is designated as part of a hedge relationship and, if it is, the type of hedge relationship. See Note 8—“Debt” for information relative to the interest rate swaps we had in effect. We currently have no derivative instruments outstanding as of December 31, 2024 or 2023.
Reclassification, Comparability Adjustment	Reclassifications. Certain amounts from prior periods have been reclassified to conform with the current year presentation.
Goodwill and Intangible Assets, Goodwill, Policy	Goodwill. Our goodwill is evaluated for impairment annually and whenever we identify certain triggering events or circumstances that would more likely than not reduce the fair value of a reporting unit below its carrying amount. In our annual evaluation of goodwill, we perform a qualitative or quantitative impairment test. Under the qualitative approach, if we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we are required to perform the quantitative analysis to determine the fair value of the reporting unit. We then compare the fair value of the reporting unit with its carrying amount and recognize an impairment loss for the amount by which the carrying amount exceeds the fair value of the reporting unit. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. We also consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. During the fourth quarters of 2024 and 2023, we performed our annual goodwill impairment assessment using qualitative tests that did not indicate a more detailed quantitative analysis was necessary. No goodwill impairment was recognized for the years ended December 31, 2024, 2023 and 2022.
Lessee, Leases	Leases. We determine whether a contract is or contains a lease at inception, whether as a lessee or a lessor. We take into consideration the elements of an identified asset, right to control and the receipt of economic benefit in making those determinations. As a lessor, we lease certain types of equipment along with the provision of services and utilize the expedient allowing us to combine the lease and non-lease components into a combined component that is accounted for (1) under the accounting standard “ Leases ” (“ASC 842”), when the lease component is predominant, and (2) under the accounting standard “ Revenue from Contracts with Customers ” (“ASC 606”), when the service component is predominant. In general, when we have a service component, it is typically the predominant element and leads to accounting under ASC 606. As a lessor, we lease certain types of equipment, often providing services at the same time. These leases can be priced on a dayrate or lump-sum basis for periods ranging from a few days to multi-year contracts. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our customer's discretion. These leases generally do not contain options to purchase, material restrictions or covenants that impact our accounting for leases. As a lessee, we lease land, buildings, vessels and equipment for the operation of our business and to support some of our service line revenue streams. These generally carry lease terms that range from days for operational and support equipment to 20 years for land and buildings. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our discretion. When the exercise of those options is reasonably certain, we include them in the lease assessment. Our leases do not contain material restrictions or covenants that impact our accounting for them, nor do we provide residual value guarantees. As a lessee, we utilize the practical expedients to not recognize leases with an initial lease term of 12 months or less on the balance sheet and to combine lease and non-lease components together and account for the combined component as a lease for all asset classes, except real estate. Right-of-use operating lease assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement or modification date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, based on the information available at commencement or modification date in determining the present value of future payments. In determining the incremental borrowing rate, we considered our external credit ratings, bond yields for us and our identified peers, the risk-free rate in geographic regions where we operate and the impact associated with providing collateral over a similar term as the lease for an amount equal to the future lease payments. Our right-of-use operating lease assets also include any lease prepayments made and exclude lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease. These options are included in the lease term when it is reasonably certain we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. See Note 4—“Leases” for more information on our operating leases.
Earnings Per Share, Policy	Earnings (Loss) per Share. For each year presented, the only difference between our annual calculated weighted-average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units.
Lessee, Operating Leases [Text Block]	LEASES Supplemental information about our operating leases follows: December 31, (in thousands) 2024 2023 Assets: Right-of-use operating lease assets $ 334,721 $ 337,554 Liabilities: Current $ 131,415 $ 78,117 Noncurrent 238,325 293,482 Lease liabilities $ 369,740 $ 371,599 December 31, 2024 2023 Lease Term and Discount Rate: Weighted-average remaining lease term (years) 6.0 6.9 Weighted-average discount rate 5.9 % 5.9 % No impairments of right-of-use operating leases were recorded in the years ended December 31, 2024 and 2023. Operating lease cost reflects the lease expense resulting from amortization over the respective lease terms of our operating leases with initial lease terms greater than 12 months. Our short-term lease cost consists of expense for our operating leases with initial lease terms of 12 months or less that are not recorded on our balance sheet.
