Accounting Policies [Abstract]

Nature of Operations [Policy Text Block]

Nature of Operations

We provide offshore support vessels and marine support services to the global offshore energy industry through the operation of a diversified fleet of offshore marine service vessels. Our revenues, net earnings and cash flows from operations are dependent upon the activity level of the vessel fleet (utilization) and the price we charge for these services (day rate). The level of our business activity is driven by the amount of installed offshore oil and gas production facilities, the level of offshore drilling and exploration activity, and the general level of offshore construction projects such as pipeline and windfarm construction and support. Our customers’ offshore activity, in turn, is dependent on crude oil and natural gas (oil and gas) prices, which fluctuate depending on the respective levels of supply and demand for oil and gas and the outlook for such levels.

In 2023, we acquired 37 platform supply vessels owned by Solstad Offshore ASA, a Norwegian public limited company, operating primarily in the North Sea, Australia and Brazil.

In 2022, we acquired Swire Pacific Offshore Holdings Ltd., a limited company organized under the laws of Bermuda (SPO), which owned 50 offshore support vessels operating primarily in West Africa, Southeast Asia and the Middle East.

Unless otherwise required by the context, the terms “we”, “us”, “our” and “company” as used herein refer to Tidewater Inc. and its consolidated subsidiaries and predecessors.

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

The consolidated financial statements included herein, presented in accordance with United States generally accepted accounting principles and stated in U.S. dollars, have been prepared by the company, pursuant to the rules and regulations of the Securities and Exchange Commission.

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The consolidated financial statements include the accounts of Tidewater Inc. and its subsidiaries. Intercompany balances and transactions are eliminated in consolidation.

Segment Reporting, Policy [Policy Text Block]

Reporting Segments

Reporting business segments are defined as a component of an enterprise for which separate financial information is available and is evaluated by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Our segments are based on geographic markets: the Americas segment, which includes the U.S. Gulf of Mexico (U.S. Gulf), Trinidad, Mexico and Brazil; the Asia Pacific segment, which includes Southeast Asia and Australia; the Middle East segment, which includes Saudi Arabia, United Arab Emirates, India and East Africa; the Europe/Mediterranean segment, which includes the United Kingdom, Norway and Egypt; and the West Africa segment, which includes Angola and other coastal regions of West Africa. Please refer to Note (14) - “Segment Information, Geographical Data and Major Customers” for disclosure related to reporting segments.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the recorded amounts of revenues and expenses during the reporting period. The accompanying consolidated financial statements include estimates for allowance for credit losses, useful lives of property and equipment, estimated net realizable value of assets held for sale and marine operating supplies, income tax provisions, impairments, fair value of assets and liabilities related to acquired vessels, fair value of available-for-sale debt securities, fair value of stock-based compensation awards, commitments and contingencies and certain accrued liabilities. We evaluate our estimates and assumptions on an ongoing basis based on a combination of historical information and various other assumptions that are considered reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. These accounting policies involve judgment and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions or if different assumptions had been used and, as such, actual results may differ from these estimates.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash Equivalents

We consider all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Restricted Cash

We consider cash as restricted when there are contractual agreements that govern the use or withdrawal of the funds.

Inventory, Policy [Policy Text Block]

Marine Operating Supplies

Marine operating supplies, which consist primarily of operating parts and supplies for our vessels as well as fuel, are stated at the lower of weighted-average cost or net realizable value.

Property, Plant and Equipment, Policy [Policy Text Block]

Properties and Equipment

Capitalization, Depreciation and Amortization

Properties and equipment acquired after fresh-start are stated at their acquisition cost. Depreciation is computed primarily on the straight-line basis beginning on acquisition date or on the date construction is completed, with salvage values of 7.5% for marine equipment, using estimated useful lives of 10 – 20 years for marine equipment and 3 – 10 years for other properties and equipment. Depreciation is provided for all vessels unless a vessel meets the criteria to be classified as held for sale. Estimated remaining useful lives are reviewed when there has been a change in circumstances that indicates the original estimated useful life may no longer be appropriate. Upon retirement or disposal of a fixed asset, the costs and related accumulated depreciation are removed from the respective accounts and any gains or losses are included in our consolidated statements of operations. 

Maintenance and Repairs

Most of our vessels require certification inspections twice in every five-year period. These costs include drydocking and survey costs necessary to ensure compliance with applicable regulations and maintain certifications for vessels with classification societies. These certification costs are typically incurred while the vessel is in drydock and may be incurred concurrent with other vessel maintenance and improvement activities. Costs related to the certification of vessels are deferred and amortized over 30 months on a straight-line basis.

Maintenance costs incurred at the time of the recertification drydocking that are not related to the certification of the vessel are expensed as incurred.

Costs related to vessel improvements that either extend the vessel’s useful life or increase the vessel’s functionality are capitalized and depreciated. Vessel modifications that are performed for a specific customer contract are capitalized and amortized over the firm contract term. Major modifications to equipment that are not being performed for a specific customer contract are capitalized and amortized over the remaining life of the equipment.

Net Properties and Equipment

The following are summaries of net properties and equipment:

(In Thousands)	December 31,		December 31,
	2024		2023
Properties and equipment:
Vessels and related equipment	$	1,727,197	$	1,716,339
Other properties and equipment		28,969		32,447
		1,756,166		1,748,786
Less accumulated depreciation and amortization		571,884		433,664
Net properties and equipment	$	1,184,282	$	1,315,122

As of  December 31, 2024, we owned 211 offshore support vessels, 210 of which were active and one of which was stacked. As of December 31, 2023, we owned 217 offshore support vessels, 215 of which were active and two of which were stacked. We consider a vessel to be stacked if the vessel crew is disembarked and limited maintenance is being performed. We reduce operating costs by stacking vessels when we do not foresee opportunities to profitably or strategically operate the vessels in the near future. Vessels are stacked when market conditions warrant and they are removed from stack when they are returned to active service, sold or otherwise disposed. We consider our current stacked vessels to be available for return to service. Stacked vessels are considered to be in service and are included in our utilization statistics. Please refer to Note (8) - “Assets Held for Sale, Asset Sales and Asset Impairments” for additional discussion of our assets held for sale including any reclassifications to or from the active fleet. Some of our vessels are pledged as security under our debt agreements. Refer to Note (4) – “Debt” for additional information regarding debt security.

To support our West Africa segment, we contracted to build two ocean-going tugs which were completed in 2023 and cost approximately $6.0 million each. We also contracted to build eight Alucat crew boats, two of which were completed in 2023 and cost approximately $4.0 million each. We expect five of the remaining six Alucat crew boats to be delivered in early 2025 and one to be delivered later in 2025. We paid $2.9 million to start the construction on these vessels, which will cost approximately $2.5 million each. During January and February of 2025, we took delivery of five Alucat crew boats and recorded debt of approximately EUR 9.4 million ($9.7 million).

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of Long-Lived Assets

We review the vessels in our active fleet for impairment whenever events occur or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. In such evaluation, the estimated future undiscounted cash flows generated by an asset group are compared with the carrying amount of the asset group to determine if a write-down may be required. With respect to vessels that are expected to remain in active service, we group together for impairment testing purposes vessels with similar operating and marketing characteristics. Stacked vessels expected to return to active service are evaluated for impairment as part of their assigned active asset group.

We estimate future cash flows based upon historical data adjusted for our best estimate of expected future market performance, which, in turn, is based on industry trends. The primary estimates and assumptions used in reviewing active vessel groups for impairment and estimating undiscounted cash flows include utilization rates, average day rates and average daily operating expenses. These estimates are made based on recent actual trends in utilization, day rates and operating costs and reflect management’s best estimate of expected market conditions during the period of future cash flows. These assumptions and estimates have changed considerably as market conditions have changed, and they are reasonably likely to continue to change as market conditions change in the future. Although we believe our assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce materially different results. Management estimates may vary considerably from actual outcomes due to future adverse market conditions or poor operating results that could result in the inability to recover the current carrying value of an asset group, thereby possibly requiring an impairment charge in the future. As our fleet continues to age, management closely monitors the estimates and assumptions used in the impairment analysis in order to properly identify evolving trends and changes in market conditions that could impact the results of the impairment evaluation.

If an asset group fails the undiscounted cash flow test, we estimate the fair value (Level 3) of that asset group and compare such estimated fair value to the carrying value of that asset group in order to determine if impairment exists.

From time to time, we may designate assets or a group of assets for disposal under a plan for disposition. Cost and related accumulated depreciation associated with assets designated for disposal under such a plan are removed from the property and equipment accounts and reclassified to assets held for sale at estimated net realizable value. Any excess of previous net book value over estimated net realizable value is charged to impairment expense. Also, we may sell or recycle assets at various times for various reasons including obsolescence that are not subject to a plan for disposal. We record gains and losses on these sales as they occur.

We consider the valuation approach for our assets held for sale to be a Level 3 fair value measurement due to the level of estimation involved in valuing assets to be recycled or sold. We estimate the net realizable value of our assets held for sale using various methodologies including third party appraisals, sales comparisons, sales agreements and recycle yard tonnage prices. Estimates generally fall in ranges rather than exact numbers due to the nature of sales of offshore vessels and industry conditions. Our value ranges depend on our expectation of the ultimate disposition of the vessel. We will in all circumstances attempt to achieve maximum value for our vessels, but also recognize that certain vessels are more likely to be recycled, especially given the time and effort required to achieve a sale and the costs incurred to maintain a vessel while searching for a buyer. We establish ranges that in many cases have the recycling value as the low end of the range and an expected open market sale value at the top of the range.

When there is no expectation within the range that is considered more likely than any other, we apply equal probability weighting to the low and high ends of the valuation range. In addition, in conjunction with the reactivation of vessels from assets held for sale to the active fleet and the concurrent valuation of such vessels at fair value, we may recapture impairment previously charged to expense related to those vessels. We do not separate our asset impairment expense by segment because of the significant movement of our assets between segments.

Please refer to Note (8) - “Assets Held for Sale, Asset Sales and Asset Impairments” for a discussion of our evaluations of long-lived assets for impairment during the years ended December 31, 2024, 2023 and 2022.

Accrued Property And Liability Losses Policy [Policy Text Block]

Accrued Property and Liability Losses

Our insurance coverage is provided by third party insurers. We establish case-based reserves for estimates of reported losses on outstanding claims, estimates received from ceding reinsurers, and reserves based on past experience of unreported losses. Such losses principally relate to our vessel operations and are included as a component of vessel operating costs in the consolidated statements of earnings. The liability for such losses and the related reimbursement receivable from reinsurance companies are classified in the consolidated balance sheets into current and noncurrent amounts based upon estimates of when the liabilities will be settled and when the receivables will be collected.

Pension and Other Postretirement Plans, Policy [Policy Text Block]

Pension Benefits

We follow the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 715, Compensation – Retirement Benefits, and use a December 31 measurement date for determining net periodic benefit costs, benefit obligations and the fair value of plan assets. Net periodic pension costs and accumulated benefit obligations are determined using several assumptions including the discount rates used to measure future obligations and expenses, retirement ages, mortality rates, expected long-term return on plan assets, and other assumptions, all of which have a significant impact on the amounts reported.

Our pension cost consists of interest costs, expected returns on plan assets, and actuarial gains and losses. We consider various factors in developing pension assumptions, including an evaluation of relevant discount rates, expected long-term returns on plan assets, plan asset allocations, expected changes in retirement benefits, analyses of current market conditions and input from actuaries and other consultants.

For the long-term rate of return, we developed assumptions regarding the expected rate of return on plan assets based on historical experience and projected long-term investment returns, which consider the plan’s target asset allocation and long-term asset class return expectations. Assumptions for the discount rate reflect the theoretical rate at which liabilities could be settled in the bond market at  December 31, 2024.

Income Tax, Policy [Policy Text Block]

Income Taxes

Income taxes are accounted for in accordance with the provisions of ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are not provided on undistributed earnings of certain non-U.S. subsidiaries and business ventures because we consider those earnings to be permanently invested abroad.

We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions would be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The recognition and measurement of tax liabilities for uncertain tax positions in any tax jurisdiction requires the interpretation of the related tax laws and regulations as well as the use of estimates and assumptions regarding significant future events. Changes in tax laws, regulations, agreements and treaties, foreign currency exchange restrictions or our level of operations or profitability in each taxing jurisdiction could have an impact on the amount of income taxes during any given year.

Revenue [Policy Text Block]

Revenue Recognition

Our primary source of revenue derives from time charter contracts of our vessels on a rate per day of service basis; therefore, vessel revenues are recognized on a daily basis throughout the contract period. The base rate of hire for a time charter contract is generally a fixed rate, provided, however, that some longer-term contracts at times include escalation clauses to recover specific additional costs.

Cost of Goods and Service [Policy Text Block]

Operating Costs

Vessel operating costs consist primarily of costs such as crew wages; repair and maintenance; insurance; fuel, lube oil and supplies; and other vessel expenses, which include costs such as brokers’ commissions, training costs, agent fees, port fees, canal transit fees, temporary importation fees, vessel certification fees, and satellite communication fees. Repair and maintenance costs include both routine costs and major repairs carried out during drydockings, which occur during the economic useful life of the vessel. Vessel operating costs, excluding drydocking cost, are recognized as incurred.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Translation

The U.S. dollar is the functional currency for all our existing international operations, as transactions in these operations are predominately denominated in U.S. dollars. Foreign currency exchange gains and losses from the revaluation of our foreign currency denominated monetary assets and liabilities are included in the consolidated statements of operations.

Earnings Per Share, Policy [Policy Text Block]

Earnings Per Share

We report both basic earnings (loss) per share and diluted earnings (loss) per share. The calculation of basic earnings (loss) per share is computed based on the weighted average number of shares of common stock outstanding. Diluted earnings (loss) per share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings (loss) per share includes the dilutive effect of stock options and restricted stock grants (both time and performance based) awarded as part of our share-based compensation and incentive plans as well as our outstanding warrants. Per share amounts disclosed in these Notes to Consolidated Financial Statements, unless otherwise indicated, are on a diluted basis.

The components of basic and diluted earnings (loss) per share, are as follows:

(In Thousands, except per share data)	Year Ended December 31,
	2024		2023		2022
Net income (loss) available to common stockholders	$	180,656	$	97,185	$	(21,749	)

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of Credit Risk and Allowance for Credit Losses

Our financial instruments that are exposed to concentrations of credit risk consist primarily of trade and other receivables from a variety of domestic, international and national energy companies. We manage our exposure to risk by performing ongoing credit evaluations of our customers’ financial condition and may at times require prepayments or other forms of collateral.

We maintain an allowance for credit loss based on expected collectability and do not believe we are generally exposed to concentrations of credit risk that are likely to have a material adverse impact on our financial position, results of operations, or cash flows. Expected credit losses are recognized on the initial recognition of our trade accounts receivable. In each subsequent reporting period, even if a loss has not yet been incurred, credit losses are recognized based on the history of credit losses and current conditions, as well as reasonable and supportable forecasts affecting collectability. We developed an expected credit loss model applicable to our trade accounts receivable and contract assets that considers our historical performance and the economic environment, as well as the credit risk and its expected development for each group of customers that share similar risk characteristics. It is our practice to write off receivables when all legal options for collection have been exhausted.

Activity in the allowance for credit losses for the three years ended December 31, 2024 is as follows:

	Trade
(In Thousands)	and
	Other Receivables
Balance at January 1, 2022	$	74,404
Current period provision for expected credit losses		414
Acquisition of Sonatide joint venture		(59,678	)

Write offs (A)		(10,969	)
Other		(331	)
Balance at December 31, 2024	$	3,184

(A) Primarily the write off of the remaining balance due from our Nigerian joint venture.

Share-Based Payment Arrangement [Policy Text Block]

Stock-Based Compensation

Stock-based compensation transactions are accounted for using a fair-value-based method. We use the Black-Scholes option-pricing model to determine the fair-value of stock-based option awards. The fair value of time based stock awards is the stock price on the grant date of the award. We use a Monte Carlo simulation model to determine the fair value of stock-based performance awards that contain market conditions.

Comprehensive Income, Policy [Policy Text Block]

Comprehensive Income (Loss)

We report total comprehensive income (loss) and its components. Accumulated other comprehensive income (loss) is comprised of any minimum pension liability for our U.S. Defined Benefits Pension Plans and an unrealized gain (loss) on a note receivable.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurements

We follow the provisions of ASC 820, for financial assets and liabilities that are measured and reported at fair value on a recurring basis. ASC 820 establishes a hierarchy for inputs used in measuring fair value. Fair value is calculated based on assumptions that market participants would use in pricing assets and liabilities and not on assumptions specific to the entity. The statement requires that each asset and liability carried at fair value be classified into one of the following categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data

Level 3: Unobservable inputs that are not corroborated by market data

Our primary financial instruments consist of cash and cash equivalents, restricted cash, trade receivables and trade payables with book values that are considered to be representative of their respective fair values.

Our cash equivalents, which are securities with maturities less than three months, are held in commercial paper, money market funds or time deposit accounts with highly rated financial institutions. The carrying value for cash equivalents is considered to be representative of its fair value due to the short duration and conservative nature of the cash equivalent investment portfolio.

In the second quarter of 2022, we exchanged $8.6 million in accounts receivable with PEMEX, the Mexican national oil company, for an equal face value amount of seven-year 8.75% PEMEX corporate bonds (PEMEX Bonds). In 2024, $8.0 million of the PEMEX Bonds were sold at their approximate book value. The PEMEX Bonds are classified as “available for sale.” As of December 31, 2024 and 2023, we have recorded zero and $(0.3) million, respectively, in mark-to-market gains (losses) related to the fair value (Level 2) of the PEMEX Bonds in other comprehensive income. The remaining PEMEX Bonds are valued at $0.7 million in our consolidated balance sheet, which is both its amortized cost and approximate fair value, as of December 31, 2024.

In addition, we disclose the fair value of our long-term debt (Level 2) in Note (4).

Government Assistance [Policy Text Block]

Governmental Assistance

During 2024, we received the following governmental assistance:

● $11.8 million in wage and sick cost refunds from the Norwegian government which was credited to our vessel operating costs in our Consolidated Statement of Operations.

During 2023, we received the following governmental assistance:

● $6.1 million in wage and sick cost refunds from the Norwegian government which was credited to our vessel operating costs in our Consolidated Statement of Operations.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Pronouncements 

From time-to-time new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) that we adopt as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on our consolidated financial statements upon adoption.

In October 2021, the FASB issued ASU 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which amends Topic 805, Business Combinations to require an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. The guidance is effective for annual and interim periods beginning after December 15, 2022 with early adoption permitted. We adopted this standard on January 1, 2023 and it did not have any impact on our consolidated financial statements and related disclosures.

In September 2022, the FASB issued ASU 2022-04, Disclosures of Supplier Finance Program Obligations, which requires disclosures about supplier finance programs including the nature of the program, activity during the period, changes from period to period and potential magnitude. The guidance is effective for annual periods beginning after December 15, 2022, with early adoption permitted. We adopted this standard on January 1, 2023, and it did not have any impact on our consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting, which requires disclosure of incremental segment information on an annual and interim basis including significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. This guidance is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024. We adopted this standard on December 31, 2024 and we have included the required disclosures in Note 14 for the three years ending December 31, 2024.

Recently Issued Accounting Standards Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes, which requires a greater disaggregation of information in the income tax rate reconciliation and income taxes paid by jurisdiction to improve the transparency of the income tax disclosures. This guidance is effective for annual periods beginning after December 15, 2024. We are currently evaluating the effect of the standard on our disclosures in our consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures to improve disclosures about certain types of expenses including purchases of inventory, employee compensation and depreciation, depletion and amortization included in commonly presented captions in the Consolidation Statements of Operations. This guidance is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. We are currently evaluating the effect of the standard on our disclosures in our consolidated financial statements.
