These Consolidated Financial Statements are unaudited and have been prepared
pursuant to instructions for the Quarterly Report on Form 10- Q required to
be filed with the Securities and Exchange Commission and do not include all
information and footnotes normally included in financial statements prepared
in accordance with generally accepted accounting principles.  Management has
reflected all adjustments which it believes are necessary to present fairly
the Company's financial position at September 30, 1998 and its results of
operations and cash flows for the periods presented.  All such adjustments
are of a normal recurring nature.  The financial statements should be read
in conjunction with the consolidated financial statements and notes thereto
included in the Registrant's Annual Report on Form 10-K for its fiscal year
ended March 31, 1998.  The results for interim periods are not necessarily
indicative of annual results.  Unless the context indicates otherwise,
references to years indicate fiscal years.

2. Current Assets

Cash and cash equivalents includes demand deposits and highly liquid
investments with original maturities of three months or fewer from the date
of the investment.  Approximately $1.5 million of the Company's cash at
March 31, 1998 was restricted and deposited in interest bearing accounts as
security in connection with legal proceedings.  Such legal proceedings were
settled in the quarter ended September 30, 1998 and the restriction was 
removed.

Prepaid expenses and other current assets as of September 30 and March 31,
1998 include spare parts of $6.7 million and $3.3 million, respectively,
primarily for the Company's ROV fleet.

In September 1998, the Company issued $100 million aggregate principal
amount of 6.72% Senior Notes dues 2010.  The net proceeds were $98.6 million
after issuance costs and were used to retire existing debt under the
Company's revolving credit facility.  The notes have an average life of ten
years and are scheduled to be paid in five equal annual installments
beginning at the end of the eighth year.

In October 1998, the Company entered into a new $80 million revolving credit
facility to replace its prior one which was scheduled to convert to a term
loan in April 1999.

The Senior Notes and the new revolving credit facility have similar
maintenance covenants relative to the level of debt to total capitalization,
fixed charge coverages and minimum net worth.

4. Shareholders' Equity                      

Shareholders' Equity consisted of the following:

5.  Income Taxes

Cash taxes paid were $5.6 million and $7.9 million for the first six months
of 1999 and 1998, respectively.

6.   Earnings Per Share

The Company has computed earnings per share in accordance with Financial
Accounting Standards Board standard number ("SFAS") 128, "Earnings Per
Share", which became effective in the third quarter of 1998.  Prior periods
comparative figures have been restated.

7.   Comprehensive Income

Effective April 1, 1998, the Company adopted SFAS 130, "Reporting
Comprehensive Income".  This statement establishes standards for reporting
and display of comprehensive income and its components in financial
statements.  Comprehensive income is the total of net income and all
non-owner changes in equity.  The amount of comprehensive income for each of
the three and six-month periods ended September 30, 1998 and 1997 and the
components of accumulated other elements of comprehensive income in
Shareholders' Equity at September 30, 1998 and March 31, 1998 are as follows:

8.   New Accounting Pronouncements

The FASB has issued SFAS 131, "Disclosures about Segments of an Enterprise
and Related Information", which establishes standards for the way that
public business enterprises report information about operating segments in
interim and annual financial statements.  As required, the Company will
adopt SFAS 131 commencing with its 1999 Annual Report on Form 10-K.

The FASB has also issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which establishes standards for the way
derivative instruments and hedging activities are reported.  It requires
that an entity recognize all derivatives as either assets or liabilities in
the statement of financial position and measure those instruments at fair
value.  Changes in a derivative's fair value are to be recognized currently
in earnings unless specific hedge accounting criteria are met.  The Company
has not yet quantified the impact, if any, on its financial statements that
may result from adoption of SFAS No. 133, which is required no later than
April 1, 2000.

Item 2.   Management's Discussion and Analysis of Financial Condition and
Results of Operations.

All statements in this Form 10-Q, other than statements of historical facts,
including, without limitation, statements regarding the Company's business
strategy, plans for future operations, and industry conditions, are
forward-looking statements made pursuant to the safe harbor provisions of
the Private Securities Litigation Reform Act of 1995.  The Company utilizes
a variety of internal and external data and management judgment in order to
develop such forward-looking information.  Although the Company believes
that the expectations reflected in such forward-looking statements are
reasonable, because of the inherent limitations in the forecasting process,
as well as the relatively volatile nature of the industries in which the
Company operates, it can give no assurance that such expectations will prove
to have been correct.  Accordingly, evaluation of future prospects of the
Company must be made with caution when relying on forward-looking information.

Material Changes in Financial Condition

The Company considers its liquidity and capital resources adequate to
support continuing operations and capital commitments.  At September 30,
1998, the Company had working capital of $66 million, including $30 million
of unrestricted cash.  At September 30, 1998, the Company had utilized none
of its available $80 million credit facility and $20 million was unused
under uncommitted lines of credit.

In order to provide longer term funding, the Company issued $100 million of
6.72% Senior Notes which are repayable in five equal annual principal
installments beginning at the end of the eighth year.  In October 1998, the
Company replaced its revolving credit facility with a new $80 million five
year revolving credit facility.

Capital expenditures were $52 million during the first six months of 1999,
as compared to $41 million during the corresponding period of the prior
fiscal year.  Capital expenditures in 1999 consisted of additions to the
Company's fleet of remotely operated vehicles ("ROVs"), multi-service
support vessel construction and subsea products facilities expansion.  Prior
fiscal year expenditures consisted of additions to the Company's fleet of
ROVs, support vessel expenditures and two out-of-service mobile offshore
platforms for potential conversion to production systems or alternative 
service.

Commitments for capital expenditures at September 30, 1998 were
approximately $20 million for subsea product manufacturing facilities and
multi-service support vessel construction.

The quarters ending June 30 and September 30 have generally been the
Company's peak in both revenues and net income for its Oilfield Marine
Services business.  However, the Company's exit from the diving sector in
the North Sea in early 1998 and the substantial number of multi-year ROV
contracts which were entered into since 1997 should reduce the seasonality
of the Company's Oilfield Marine Services operations.  Revenues and net
income in the Offshore Field Development and Advanced Technologies
businesses are generally not seasonal.

Oilfield Marine Services

Revenue and gross margin information is as follows:

                           Three Months Ended      Six Months Ended
                             September 30,           September 30,

  Gross margins             12,452    12,332         24,162   22,694
  Gross margin %                22%       26%            22%      23%


Revenue for the Oilfield Marine Services segment increased due to the
expansion of the company's work class ROV fleet and increased sales of
diving and engineering project management services.  Gross margins showed a
slight improvement on the strength of improved profitability associated with
engineering project services.

The gross margin percentage in the three months ended September 30, 1998 was
lower than that of the comparable period of the prior year as a result of
higher ROV-related training and payroll costs, a higher subcontractor
component in work performed and inefficiencies due to an unusually high
number of tropical storms in or threatening Gulf of Mexico work areas. 
Additionally the gross margin percentage from the year-earlier quarter was
unusually high as the gross margin percentage for all of 1998 was 22%.


Offshore Field Development

Revenue and gross margin information is as follows:

                          Three Months Ended      Six Months Ended

                             (in thousands, except percentages)

  Revenues                  $28,697  $21,760       $56,351   $46,388
  Gross margins               6,781    2,588        14,027     6,888
  Gross margin %                 24%     12%            25%       15%

Revenues and gross margins were higher in the 1999 periods compared to the
corresponding periods of the prior year as a result of increased product
sales and the acquisition of a production barge in January 1998.  Gross
margins also benefitted from higher profitability on project management
work.  The Company's FPSO OCEAN PRODUCER continued to operate offshore West
Africa under a contract which expires in January 2000.

Advanced Technologies

Revenue and gross margin information is as follows:

  Revenues                 $25,433   $21,291      $43,986   $42,265
  Gross margins              4,299     5,712        6,830     9,983
  Gross margin %                17%       27%          16%       24%

Revenues rose on increased activity levels for subsea telecommunications
cable services and the design and assembly of large, dynamic, animated
figures for theme parks.  However, gross margins declined due to a reduction
in civil engineering and construction work and lower profitability on search
and recovery services.

Other

Interest expense for the three and six month periods ended September 30,
1998 increased compared to the corresponding periods of the prior year as
the Company incurred debt to fund the acquisition of additional equipment. 

The provisions for income taxes were related to U.S. income taxes which were
provided at estimated annual effective rates using assumptions as to
earnings and other factors which would affect the tax calculation for the
remainder of the fiscal year, and to the operations of foreign branches and
subsidiaries which were subject to local income and withholding taxes.

Year 2000.

The Year 2000 problem is the result of computer programs which were written
using two digits rather than four to define the applicable year.  Programs
that have time sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000.  The Company has been reviewing its
computer systems to identify potential problem areas.  Based upon its
assessment to date, much of the cost of compliance is included in regular
system and equipment upgrades which are planned or are in progress.  The
Company does not expect the cost of compliance to have a material effect on
its financial position, results of operations or liquidity.  The Company
will also be working with its major trading partners to avoid operational
disruptions.   However, there is no assurance that the systems of other
companies on which the Company relies will be converted timely and will not
have an adverse effect on the Company.
