                 McDermott Reports First Quarter 2004 Results;
              Net Loss of $10.9 million, $0.17 per diluted share,
     includes B&W settlement revaluation benefit of $2.7 million after tax

    NEW ORLEANS--(BUSINESS WIRE)--May 10, 2004--McDermott
International Inc. (NYSE:MDR) ("McDermott" or the "Company") today
reported a net loss from operations of $10.9 million, or $0.17 per
diluted share, for the first quarter of 2004, compared to income from
continuing operations of $29.6 million, or $0.46 per diluted share,
for the corresponding period in 2003. Net income for the first quarter
of 2003 was $35.5 million, or $0.55 per diluted share, which included
income from discontinued operations of $2.2 million and the cumulative
effect of an accounting change of $3.7 million. Additionally, in 2003,
both income from continuing operations and net income included a
benefit of $23.6 million, after tax, in the quarterly adjustment
related to the estimated costs of The Babcock & Wilcox Company ("B&W")
Chapter 11 settlement compared to only $2.7 million in 2004. Weighted
average common shares outstanding on a fully diluted basis were
approximately 65.3 million and 65.1 million for March 31, 2004 and
March 31, 2003, respectively.
    Revenues in the first quarter of 2004 were $499.3 million,
compared to $512.7 million in the corresponding period in 2003. The
change in revenues is due to reduced activity at J. Ray McDermott,
S.A. and its subsidiaries ("J. Ray"), partially offset by increased
revenues at BWX Technologies Inc. ("BWXT").
    The first quarter 2004 operating loss was $2.1 million, which
included $15.3 million of corporate qualified pension expense,
compared to first quarter 2003 operating income and corporate
qualified pension expense of $13.9 million and $18.0 million,
respectively.
    "Our results in the first quarter of 2004 significantly improved
sequentially from the fourth quarter 2003, but declined versus a year
ago, as the reduced activity level at J. Ray resulted in fixed
operating costs that weren't fully absorbed by our projects," said
Bruce W. Wilkinson, chairman of the board and chief executive officer
of McDermott. "We continue to be optimistic that the remaining
projects in loss positions at J. Ray will soon be behind us, and we
were pleased that there were no additional charges on these projects
during the first quarter. Further, we expect that new projects will be
added to J. Ray's backlog, and J. Ray will manage its costs to reflect
an expected decrease in revenues in 2004. In addition, due to the
various tax jurisdictions where we operate, approximately 45 percent
of our total net loss related to provision for income taxes."
    The Company's other expense for the first quarter of 2004 was $3.9
million, compared to other income of $22.7 million in the first
quarter of 2003. The year-over-year decline is primarily due to a
$21.7 million reduction, pretax, in the quarterly adjustment related
to the estimated costs of the B&W Chapter 11 settlement. This
revaluation will continue to fluctuate on a quarterly basis and is
largely dependent on the quarterly price movement in McDermott's stock
price. Provision for income taxes was $4.9 million in the first
quarter 2004, compared to $7.0 million in the first quarter 2003.

    RESULTS OF OPERATIONS
    2004 First Quarter Compared to 2003 First Quarter

    Marine Construction Services Segment ("J. Ray")

    Revenues in the Marine Construction Services segment were $365.8
million in the 2004 first quarter, a decrease of $29.2 million from a
year ago. The year-over-year reduction resulted from decreased
activity on fabrication and marine installation projects in the Middle
East and Asia Pacific regions.
    Segment loss for the 2004 first quarter was $3.6 million compared
to a segment income in the first quarter 2003 of $16.6 million. Major
projects contributing income to the 2004 first quarter were the
project in Azerbaijan for the AIOC, a pipelay project for Shell in the
Gulf of Mexico, and fabrication projects for BP in Morgan City, La.,
offset by lower overall activity at J. Ray available to cover fixed
operating costs. Selling, general and administrative expenses were
$23.4 million, compared to $18.3 million in the 2003 first quarter.
    At March 31, 2004, J. Ray's backlog of $1.3 billion included $69
million related to uncompleted work on the Front Runner spar, $14
million on the Belanak project and $19 million related to the Carina
Aries project. J. Ray's backlog was $1.4 billion and $2.0 billion at
Dec. 31, 2003 and March 31, 2003, respectively.

    Government Operations Segment ("BWXT")

    Revenues in the Government Operations segment increased $15.8
million to $133.5 million in the 2004 first quarter, primarily due to
higher volumes from the manufacture of nuclear components for certain
U.S. government programs.
    Segment income decreased $3.9 million to $19.7 million in the 2004
first quarter, primarily due to a $3.3 million benefit received during
the first quarter of 2003 related to a contract settlement and an
aggregate of $3.6 million in the first quarter of 2004 related to
increased bid and proposal costs, higher selling, general and
administrative costs and a reduction in equity income from investees.
    "BWXT continues to produce strong operating and financial
results," added Wilkinson. "Although the operating income in the 2004
quarter was down slightly compared to a year ago, we continue to
expect BWXT to produce improved results year-over-year on a comparable
basis."
    At March 31, 2004, BWXT's backlog was $1.7 billion, compared to
backlog of $1.8 billion and $1.6 billion at Dec. 31, 2003 and March
31, 2003, respectively.

    Corporate

    Unallocated corporate expenses were $18.3 million in the 2004
first quarter, a decrease of $8.1 million compared to the 2003 first
quarter, primarily due to a $2.7 million reduction in corporate
qualified pension plan expense, reduced costs at all corporate cost
centers and increased allocation of corporate costs to the operating
segments.

    Other Income and Expense

    Net interest expense was $7.5 million in the 2004 first quarter
compared to $2.7 million in the 2003 first quarter, due to the
issuance of J. Ray's 11 percent senior secured notes in December 2003.
    During the 2004 first quarter, revaluation of certain components
of the estimated settlement cost related to the Chapter 11 proceedings
involving B&W resulted in a decrease in the estimated cost of the
settlement to $125.3 million, resulting in the recognition of other
income of $2.4 million ($2.7 million after tax). The decrease in the
first quarter 2004 estimated settlement cost is due primarily to a
decrease in the trading price of McDermott's common stock from $11.95
per share at Dec. 31, 2003 to $8.39 per share at March 31, 2004. As
discussed in the Company's annual report on Form 10-K for the year
ended Dec. 31, 2003, the Company is required to revalue certain
components of the estimated settlement cost quarterly and at the time
the securities are issued, assuming the settlement is finalized.
    Provision for income taxes during the first quarter of 2004 was
$4.9 million, compared to $7.0 million during the first quarter of
2003. Despite the Company's consolidated pretax loss from operations,
the Company recognized a net provision for income taxes, reflecting
the tax obligations in many of the jurisdictions in which it operates,
combined with its inability to recognize tax benefits in several
jurisdictions where losses were incurred.

    DISCONTINUED OPERATIONS

    In August 2003, the Company completed the sale of Menck GmbH
("Menck"), formerly a component of the Marine Construction Services
segment. Accordingly, the Company has reported the results of
operations for Menck as discontinued operations. In the first quarter
2003, the Company recorded income of $2.2 million, after tax,
associated with the operations of Menck.

    THE BABCOCK & WILCOX COMPANY

    The Company wrote off its remaining investment in B&W of $224.7
million during the second quarter of 2002 and has not consolidated B&W
with McDermott's financial results since B&W's Chapter 11 bankruptcy
filing in February 2000. B&W's revenues were $377.1 million in the
first quarter of 2004, a decrease of $3.9 million compared to the
first quarter of 2003. B&W's net income for the 2004 first quarter was
$24.2 million, an increase of $10.8 million versus the corresponding
period in 2003.

    LIQUIDITY

    On a consolidated basis, the Company incurred negative cash flows
for the first quarter of 2004. J. Ray expects to incur negative cash
flow from operations during two of the remaining three quarters in
2004, due to the cash outflow on the three spar projects, the Carina
Aries project and the Belanak project, for which substantial income
statement expenses have already been recorded. The Company expects
negative cash flow on a consolidated basis for one of the remaining
three quarters in 2004, reflecting J. Ray's negative cash flow.
    Completion of these projects has and will continue to put a strain
on J. Ray's current liquidity. J. Ray intends to fund its negative
cash flow in 2004 with cash on hand, including cash expected to be
made available when it obtains a new letter-of-credit facility, as
well as through sales of non-strategic assets.
    In December 2003, J. Ray issued $200 million of 11 percent, senior
secured notes due 2013, however over half of the proceeds from these
notes are currently restricted, to collateralize letters of credit and
a temporary interest reserve. J. Ray is currently negotiating a
secured, $75 million letter-of-credit facility. This facility, if
fully utilized, would enable J. Ray to replace most of the
approximately $80 million of existing letters of credit which are
currently cash collateralized.
    J. Ray's ability to obtain a new letter-of-credit facility will
depend on numerous factors, including market conditions, J. Ray's
performance and the negotiation of acceptable terms and conditions. In
addition, J. Ray's ability to use the proceeds from sales of assets to
fund its working capital requirements is limited under the terms of
the indenture governing its senior secured notes. If J. Ray is unable
to obtain a new letter of credit facility or a sufficient amount of
available proceeds from sales of non-strategic assets, J. Ray's
ability to pursue additional projects, which often require letters of
credit, and its liquidity, will be adversely impacted. These factors
continue to cause substantial doubt about J. Ray's ability to continue
as a going concern. As of May 6, 2004, J. Ray had approximately $68
million of unrestricted cash available.

    POTENTIAL RECOVERIES

    As indicated in its March 1, 2004 press release, the Company
believes that it has the opportunity to recover in future periods up
to $25 million of the losses it recorded during 2003. McDermott is
pleased to announce that since March 1, 2004, J. Ray has negotiated
approximately $17 million of its potential recoveries. Approximately
$5 million was included in its results for the first quarter 2004 and
the remaining $12 million will be recorded in the appropriate future
periods.
