TIDEWATER INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



(1)  Interim Financial Statements

     The consolidated financial information for the interim periods presented
     herein has not been audited by independent accountants, but in the opinion
     of management, all adjustments (consisting only of normal recurring
     adjustments) necessary for a fair presentation of the condensed
     consolidated balance sheets and the condensed consolidated statements of
     earnings and cash flows at the dates and for the periods indicated have
     been made.  Results of operations for interim periods are not necessarily
     indicative of results of operations for the respective full years.

(2)  Earnings per Share Data

     Primary and fully diluted earnings per share data are computed on the
     weighted average number of shares and dilutive equivalent shares of common
     stock (stock options and restricted stock grants) outstanding during each
     period using the treasury stock method.

(3)  Income Taxes

     Income tax expense for interim periods is based on estimates of the
     effective tax rate for the entire fiscal year.  The effective tax rate was
     34% for the quarter and six-month period ended September 30, 1997
     excluding a $4 million (or $.07 per share) reduction in deferred taxes
     resulting from the lowering of United Kingdom corporate income tax rates
     which had the effect of reducing the effective tax rate for the quarter
     and six-month period ended September 30, 1997 to 30% and 32%,
     respectively.  For the quarter and six-month period ended September 30,
     1996 the effective tax rate was 32%.

(4)  Marine Acquisitions

     During the quarter ended June 30, 1997 the company acquired all of the
     shares of O.I.L. Ltd. (O.I.L.) from Ocean Group plc in exchange for a cash
     payment of 328 million pounds sterling or approximately $534 million.  In
     addition, a 3 million pound sterling, or approximately $5 million, advance
     payment was made for the net working capital of O.I.L., with the final
     purchase price to be adjusted for the final net working capital of O.I.L.
     as of the closing date.  Available cash of $39 million and borrowings of
     $500 million were used to fund the purchase.  Prior to the purchase O.I.L.
     was principally engaged in the business of operating approximately 100
     marine vessels, primarily platform supply and anchor handling
     towing-supply vessels, in several international offshore oil and gas
     exploration areas outside of the United States.  The total estimated cost
     of the acquisition of $626 million, which includes $65.6 million of
     deferred income tax liability, was allocated under the purchase method of
     accounting based on the fair value of the assets acquired and liabilities
     assumed, including accruals for the estimated balance of O.I.L. working
     capital and professional fees, severance and other transaction





                                       5
   6
        costs and the related deferred tax effect of the acquisition.  Goodwill
        of approximately $354 million has been recorded in the Condensed
        Consolidated Balance Sheet.

        The results of O.I.L.'s operations have been consolidated with the
        company's effective May 16, 1997.  Pro forma combined results of
        operations of the company and of O.I.L. including appropriate purchase
        accounting adjustments for the quarter ended September 30, 1996 and for
        the six-month periods ended September 30, 1997 and 1996 as though the
        acquisition had taken place on April 1 of the respective years are as
        follows:

Net earnings                                 $ 29,898      114,433       49,996

   per common share                          $    .48         1.88          .80



        The $500 million of debt incurred to finance the O.I.L. acquisition was
        borrowed pursuant to a $600 million Revolving Credit and Term Loan
        agreement with several banks and consists of a $400 million term loan
        and $100 million borrowed under the $200 million revolving credit
        facility of the agreement.  The term loan is payable in quarterly
        installments and bears interest at fluctuating rates subject to certain
        options chosen in advance by the company.

        On June 30, 1997 the company acquired the remaining 50% equity interest
        in nine towing-supply and supply vessels previously owned and operated
        by joint-venture companies in Australia for a cash payment of $13.2
        million and issuance of debt totalling $14.0 million.  The debt has
        been discounted to yield interest at 7% and is to be repaid in
        semi-annual installments.  The total estimated cost of the acquisition
        of $30 million was allocated under the purchase method of accounting
        based on the fair value of the assets acquired and liabilities assumed,
        including accruals for professional fees, severance and other
        transaction costs and the related deferred tax effect of the
        acquisition.  Goodwill of approximately $10.7 million has been recorded
        in the Condensed Consolidated Balance Sheet.

(5)     The Internal Revenue Service has notified the company of proposed
        deficiencies aggregating approximately $17.5 million of additional
        income taxes resulting from audits of the company's income tax returns
        for the years ended March 31, 1993, 1994 and 1995.  Additionally, the
        company is the defendant to several alleged labor-law pay violations
        claimed by certain current and former employees in various areas of the
        world where its marine vessel operations are conducted.  While the
        amount, if any, of such claims for which the company ultimately may be
        held liable is not presently determinable, if the claimants and all
        similarly situated employees and former employees who might file claims
        were successful, the aggregate amount of the company's liability, based
        on available information, could approximate $15 million.

        In the quarter ended September 30, 1997 the company provided an
        additional reserve of $8 million for the possible adverse outcome of
        the above matters.  In management's opinion, the amount of the
        company's liability in excess of established reserves, if any, will not
        have a material adverse effect on the company's financial position or
        the results of its ongoing operations.

                      INDEPENDENT AUDITORS' REVIEW REPORT




The Board of Directors and Shareholders
of Tidewater Inc.:



We have reviewed the accompanying condensed consolidated balance sheet of
Tidewater Inc. and subsidiaries as of September 30, 1997, and the related
condensed consolidated statements of earnings and cash flows for the
three-month and six-month periods ended September 30, 1997.  These financial
statements are the responsibility of the company's management.  The condensed
consolidated balance sheet and the related condensed consolidated statements of
earnings and cash flows of Tidewater Inc. and subsidiaries as of September 30,
1996, and for the three-month and six-month periods then ended were reviewed by
other accountants whose report dated October 18, 1996 stated that they were not
aware of any material modifications that should be made to those statements for
them to be in conformity with generally accepted accounting principles.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, which will be
performed for the full year with the objective of expressing an opinion
regarding the financial statements taken as a whole.  Accordingly, we do not
express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying condensed consolidated financial statements at
September 30, 1997, and for the three-month and six-month periods then ended
for them to be in conformity with generally accepted accounting principles.

The consolidated financial statements for the year ended March 31, 1997, from
which the accompanying condensed balance sheet was derived, were audited by
other accountants and they expressed an unqualified opinion on those financial
statements in their report dated April 30, 1997.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS


The company provides services and equipment to the international energy
industry through its marine and compression divisions.  Revenues, net earnings
and cash flows from operations are dependent upon activity levels of the marine
vessel fleet and the natural gas compression rental fleet.  Activity levels for
the marine vessel fleet and the natural gas compression rental fleet are
ultimately dependent upon oil and natural gas prices which, in turn, are
determined by the supply/demand relationship for oil and natural gas.  The
following discussion should be read in conjunction with the unaudited condensed
consolidated financial statements and related disclosures.

In accordance with the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995, the company notes that certain statements set
forth in this Quarterly Report on Form 10-Q which provide other than historical
information and which are forward looking, involve risks and uncertainties that
may impact the company's actual results of operations.  The company faces many
risks and uncertainties, many of which are beyond the control of the company,
including fluctuations in oil and gas prices; changes in capital spending by
customers in the energy industry for exploration, development and production;
unsettled political conditions, civil unrest and governmental actions,
especially in higher risk countries of operations; foreign currency controls
and environmental and labor laws.  Readers should consider all of these risk
factors as well as other information contained in this report.

During the current quarter the Board of Directors authorized management to
pursue various alternatives for possibly monetizing the company's investment in
the natural gas compression division.  Should a transaction occur, it would
allow management to fully concentrate its efforts on the marine division.

MARINE DIVISION

The Marine division provides a diverse range of services and equipment to the
offshore energy  industry.  Fleet size, utilization and vessel day rates
primarily determine the amount of revenues and operating profit because
operating costs and depreciation do not change proportionally when revenue
changes.  Operating costs principally consist of crew costs, repair and
maintenance, insurance, fuel, lube and supplies.  Fleet size and utilization
are the major factors which affect crew costs.  The timing and amount of repair
and maintenance costs are influenced by vessel age and scheduled drydockings to
satisfy safety and inspection requirements mandated by regulatory agencies.
Whenever possible, vessel drydockings are done during seasonally slow periods
to minimize any impact on vessel operations and are only done if economically
justified, given the vessel's age and physical condition.  The following tables
compare revenues, operating expenses (excluding general and administrative
expense and depreciation expense) and operating margins of the Marine
division's owned and operated vessel fleet for the quarters and six-month
periods ended September 30 and for the quarter ended June 30, 1997:

=================================================================================================


Current quarter and six-month operating margins rose considerably above the
respective amounts from fiscal 1997 due to a 41% increase in average day rates
for the worldwide vessel fleet partially offset by higher operating costs.  The
rise in average day rates for the worldwide fleet is the result of greater
demand in the U.S. Gulf of Mexico and internationally for the services provided
by the company.  Higher current quarter and six-month operating costs when
compared with fiscal 1997's respective amounts are attributable to a larger
international-based vessel fleet due to the O.I.L. and Australian acquisitions,
increased costs associated with attracting, training and retaining qualified
vessel personnel and a greater number of vessel drydockings.

Current quarter operating margins rose above the preceding quarter due to the
combination of higher average day rates for the worldwide vessel fleet being
partially offset by higher operating costs.  Continued strong demand in the
U.S.  Gulf of Mexico and better market conditions in certain international
locations were the reasons for the increase in average vessel dayrates.  Higher
operating costs are principally due to the expansion of the international-based
vessel fleet as a result of the O.I.L. and Australian acquisitions.  Amounts
for the quarter ended June 30, 1997 included activity for the O.I.L. fleet for
only half of the quarter as the acquisition was effective May 16, 1997 and did
not include any activity for the vessels acquired from Australian joint-venture
companies as the remaining 50% equity interest was purchased on June 30, 1997.

Revenues, operating expenses (excluding general and administrative expense and
depreciation expense) and operating margins of brokered vessels, shipyard and
other activities for the quarters and six-month periods ended September 30 and
for the quarter ended June 30, 1997 were:

Marine fleet utilization is determined primarily by market conditions and to a
lesser extent by drydocking requirements.  Utilization of the domestic-based
fleet, which operates in U.S. waters, is primarily influenced by offshore
activity related to the exploration, development and production of natural gas
in the U.S. Gulf of Mexico; whereas, utilization of the international-based
fleet, which operates in waters other than the United States, is primarily
influenced by offshore activity related to the exploration, development and
production of oil.  Marine vessel day rates are determined by the demand
created through the level of offshore exploration, development and production
spending by energy exploration and production companies relative to the supply
of offshore service vessels.  Suitability of equipment and the degree of
service provided also influence vessel day rates.  The following two tables
compare day-based Marine fleet utilization percentages and average day rates by
vessel class and in total for the quarters and six-month periods ended
September 30 and for the quarter ended June 30, 1997:

COMPRESSION DIVISION

The Compression division provides natural gas compression services and
equipment for a variety of applications primarily in the energy industry.
Rental revenues are determined, for the most part, by utilization and fleet
size.  Utilization is affected by natural gas storage levels and by the number
and age of producing oil and natural gas wells which, in turn, are dependent
upon the price levels of oil and natural gas.  Quality of service, availability
and rental rates for equipment are also major factors which affect utilization.
Operating expenses are generally consistent from period-to-period and usually
vary in the short-term due to fluctuations in the amount of repair and
maintenance expense.  Long-term growth in operating expenses will occur
primarily as a result of increased fleet size and general inflationary factors.
Compression division operating profit is primarily determined by operating
margins from rental gas compression operations.  The following tables compare
revenues, operating expenses (excluding general and administrative expense and
depreciation expense), operating

Fiscal 1998 second quarter and six-month operating margins rose above the
respective prior year's amounts due to higher utilization and rental rates for
a larger compressor fleet being partially offset by higher repair and
maintenance costs.  The increase in utilization and rental rates resulted from
greater demand for natural gas compression services and the increase in repair
and maintenance costs was due to a greater number of compressor overhauls.
Current quarter operating margins were consistent with preceding quarter
amounts.

The Compression division also designs, fabricates and installs engineered
compressor systems and sells related parts and equipment.  The following table
compares revenues, costs of sales and sales margins for equipment and parts
sales for the quarters and six-month periods ended September 30 and for the
quarter ended June 30, 1997:

Fluctuations in the level of equipment and parts sales for the periods
presented are due to the timing of sales of engineered products.  Fluctuations
in gross profit margin percentages are the result of competitive market forces.
Costs of sales consist primarily of wages and benefits and material costs
associated with the design, fabrication and installation of packaged compressor
systems.

Additional investment in the natural gas compression rental fleet for the
current year-to-date period totaled $8.2 million for additional natural gas
compressors and modifications of existing equipment to meet customer
requirements.

CORPORATE

During the quarter ended June 30, 1997 the company acquired all of the shares
of O.I.L. Ltd. (O.I.L.) from Ocean Group plc in exchange for a cash payment of
328 million pounds sterling or approximately $534 million.  In addition, a 3
million pound sterling, or approximately $5 million, advance payment was made
for the net working capital of O.I.L., with the final purchase price to be
adjusted for the final net working capital of O.I.L. as of the closing date.
Available cash of $39 million and borrowings of $500 million were used to fund
the purchase.  Prior to the purchase O.I.L. was principally engaged in the
business of operating approximately 100 marine vessels, primarily platform
supply and anchor handling towing-supply vessels, in several international
offshore oil and gas exploration areas outside of the United States.  The total
estimated cost of the acquisition of $626 million, which includes $65.6 million
of deferred income tax liability,  was allocated under the purchase method of
accounting based on the fair value of the assets acquired and liabilities
assumed, including accruals for the estimated balance of O.I.L. working capital
and professional fees, severance and other transaction costs and the related
deferred tax effect of the acquisition.  Goodwill of approximately $354 million
has been recorded in the Condensed Consolidated Balance Sheet.

The $500 million of debt incurred to finance the O.I.L. acquisition was
borrowed pursuant to a $600 million Revolving Credit and Term Loan agreement
with several banks and consists of a $400 million term loan and $100 million
borrowed under the $200 million revolving credit facility of the agreement.
The term loan is payable in quarterly installments and bears interest at
fluctuating rates subject to certain options chosen in advance by the company.

On June 30, 1997 the company acquired the remaining 50% equity interest in nine
towing-supply and supply vessels previously owned and operated by joint-venture
companies in Australia for a cash payment of $13.2 million and issuance of debt
totalling $14.0 million.  The debt has been discounted to yield interest at 7%
and is to be repaid in semi-annual installments.  The total estimated cost of
the acquisition of $30 million was allocated under the purchase method of
accounting based on the fair value of the assets acquired and liabilities
assumed, including accruals for professional fees, severance and other
transaction costs and the related deferred tax effect of the acquisition.
Goodwill of approximately $10.7 million has been recorded in the Condensed
Consolidated Balance Sheet.

Financing activities for the six months ended September 30, 1997 provided
$408.8 million of cash and included borrowings of $500 million for the
acquisition of O.I.L. Ltd discussed above.  In addition to $18.0 million of
scheduled payments, principal payments on long-term debt include $50 million of
repayments on the revolving line of credit and repayment of $14.8 million of
debt assumed from the O.I.L. and Australian joint-venture acquisitions.  Higher
dividend payments are the result of the fiscal 1997 second quarter increase in
the per share dividend from $.125 per share to $.15 per share.

General and administrative expenses for the quarters and six-month periods
ended September 30 and for the quarter ended June 30, 1997 consist of the
following:

The Internal Revenue Service has notified the company of proposed deficiencies
aggregating approximately $17.5 million of additional income taxes resulting
from audits of the company's income tax returns for the years ended March 31,
1993, 1994 and 1995.  Additionally the company is the defendant to several
alleged labor-law pay violations claimed by certain current and former
employees in various areas of the world where its marine vessel operations are
conducted.  While the amount, if any, of such claims for which the company
ultimately may be held liable is not presently determinable, if the claimants
and all similarly situated employees and former employees who might file claims
were successful, the aggregate amount of the company's liability, based on
available information, could approximate $15 million.

In the quarter ended September 30, 1997 the company provided an additional
reserve of $8 million for the possible adverse outcome of the above matters.
In management's opinion, the amount of the company's liability in excess of
established reserves, if any, will not have a material adverse effect on the
company's financial position or the results of its ongoing operations.

INFLATION AND CURRENCY FLUCTUATIONS

Because of its significant international operations, the company is exposed to
currency fluctuations and exchange risks.  To minimize the financial impact of
these items the company attempts to contract a majority of its services in
United States dollars.

Day-to-day operating costs are generally affected by inflation.  However,
because the energy services industry requires specialized goods and services,
general economic inflationary trends may not affect the company's operating
costs.  The major impact on operating costs is the level of offshore
exploration, development and production spending by energy exploration and
production companies.  As this spending increases, prices of goods and services
used by the oil and gas industry and the energy services industry will
increase.  Future improvements in vessel day rates and compressor rental rates
may buffer the company from the inflationary effects on operating costs.

ENVIRONMENTAL MATTERS

During the ordinary course of business the company's operations are subject to
a wide variety of environmental laws and regulations.  The company attempts to
comply with these laws and regulations in order to avoid costly accidents and
any related environmental damage.
