Exhibit 99.1

                 McDermott Reports Fourth Quarter 2005
    Results; Net Income of $36.1 Million, $0.48 Per Diluted Share;
 Represents the Last Quarter without Babcock & Wilcox Consolidated in
                          Financial Results

    HOUSTON--(BUSINESS WIRE)--March 1, 2006--McDermott International,
Inc. (NYSE:MDR) ("McDermott" or the "Company") today reported net
income of $36.1 million, or $0.48 per diluted share, for the 2005
fourth quarter, compared to reported net income of $42.5 million, or
$0.61 per diluted share, for the corresponding period in 2004. Both
periods exclude the results of operations of The Babcock & Wilcox
Company ("B&W"), which was deconsolidated from McDermott's reported
results from February 2000 through February 2006. Weighted average
common shares outstanding on a fully diluted basis were approximately
74.9 million and 69.6 million for the quarters ended December 31, 2005
and December 31, 2004, respectively.
    McDermott's revenues in the fourth quarter of 2005 were $398.6
million, compared to $473.7 million in the corresponding period in
2004, reflecting decreases at both consolidated segments. Operating
income was $55.5 million in the 2005 fourth quarter, compared to the
2004 fourth quarter operating income of $72.5 million, which included
a net benefit of $54.7 million of specially identified items in last
year's quarter.
    With the announcement of B&W's revised Chapter 11 settlement,
which is now effective, McDermott suspended recording the quarterly
non cash adjustment associated with B&W's previously negotiated
settlement in the third quarter of 2005. In the fourth quarter of
2004, McDermott recorded an after-tax revaluation expense of $9.5
million associated with this adjustment.
    "The fourth quarter culminated a very successful 2005 for our
Company," said Bruce W. Wilkinson, Chairman of the Board and Chief
Executive Officer of McDermott. "McDermott reported full-year
consolidated earnings per share of $2.72, increased backlog at all of
our major subsidiaries and resolved B&W's Chapter 11 reorganization.
Beginning in March, McDermott's financial statements will once again
include B&W's results in our Power Generation Systems segment, and
will reflect our strong position in the coal, nuclear and oil & gas
markets."
    For the full year 2005, McDermott generated revenues of $1.86
billion and produced operating income of $225 million, compared to
$1.92 billion and $145.9 million, respectively, for the full year
2004. Net income for the full year 2005 was $198.0 million, or $2.72
per diluted share, which included a $50.4 million tax valuation
allowance benefit. For the full year 2004, McDermott's net income was
$61.6 million, or $0.90 per diluted share.

    RESULTS OF OPERATIONS

    2005 Fourth Quarter Compared to 2004 Fourth Quarter

    Marine Construction Services Segment ("J. Ray")

    Revenues in the Marine Construction Services segment were $253.0
million in the 2005 fourth quarter, compared to $317.2 million for the
same period a year ago. The year-over-year decrease in revenues
resulted primarily from lower fabrication activity in the Gulf of
Mexico, Middle East and Caspian regions, as well as lower marine
activity in the Gulf of Mexico, partially offset by increased revenues
from international marine projects.
    Segment income for the 2005 fourth quarter was $36.3 million,
compared to $36.7 million in the 2004 fourth quarter. Major items
contributing to operating income in the 2005 fourth quarter were
international marine projects, as well as Middle East and Caspian
fabrication projects and associated change orders. Operating income in
the 2004 fourth quarter included a net benefit of $23.8 million, in
the aggregate, from favorable contract cost adjustments on certain
loss projects, gains on asset sales and other items.
    At December 31, 2005, J. Ray's backlog was $1.8 billion, compared
to backlog of $1.2 billion and $1.7 billion at December 31, 2004 and
September 30, 2005, respectively.

    Government Operations Segment ("BWXT")

    Revenues in the Government Operations segment were $145.6 million
in the 2005 fourth quarter, compared to $156.5 million for the same
period a year ago. The decrease was primarily due to lower volumes in
the manufacture of nuclear components for certain U.S. Government
programs partially offset by increased revenues from engineering
services for U.S. Department of Energy sites, as well as increased
uranium downblending activity.
    Segment income for the 2005 fourth quarter was $26.3 million,
compared to $29.5 million in the 2004 fourth quarter. The decrease was
primarily due to the corporate allocation to BWXT of $2.9 million
related to qualified pension expense in the fourth quarter of 2005,
which in 2004 and prior periods was recorded in the corporate segment.
    At December 31, 2005, BWXT's backlog was $1.8 billion, compared to
backlog of $1.7 billion and $1.5 billion at December 31, 2004 and
September 30, 2005, respectively.

    Corporate

    Unallocated corporate expenses were $11.9 million in the 2005
fourth quarter, compared to corporate income in the 2004 fourth
quarter of $6.2 million, which included a $27.7 million gain on a U.K.
pension plan which more than offset other corporate expenses in last
year's fourth quarter. Corporate qualified pension expense in the
fourth quarter of 2005 improved by approximately $16.0 million
compared to the fourth quarter of 2004, as a result of the previously
announced spin-off of B&W's pension plan and the allocation to
McDermott's Government Operations segment of the applicable pension
expense related to that segment.

    Other Income and Expense

    The Company's other expense, net, for the fourth quarter of 2005
was $1.4 million, compared to $19.7 million in the fourth quarter of
2004. The expense reduction was primarily due to an $11.3 million
improvement in net interest income/expense.
    In addition, as mentioned above, during the 2005 third quarter,
McDermott suspended the revaluation of certain components related to
the previously negotiated settlement of the B&W Chapter 11
proceedings. The recently completed settlement will be recorded in
McDermott's financial statements during the first quarter of 2006. See
McDermott's Form 10-K for the year ended December 31, 2005 for
additional information regarding the accounting for the completed B&W
settlement.

    THE BABCOCK & WILCOX COMPANY

    The Babcock & Wilcox Company is a leading provider of technology,
service, parts and equipment for the worldwide power generation
industry. With a business history exceeding 138 years, B&W's power
systems and equipment are found at over 800 utilities spanning over 90
countries.
    On February 22, 2006, B&W effected its plan of reorganization and
has now emerged from its asbestos-related Chapter 11 proceedings,
which were initiated in February 2000. Beginning in March 2006, B&W's
financial results will once again be consolidated with McDermott's
reported financial statements, representing the vast majority of
operations in the Company's Power Generation Systems segment.
    Although deconsolidated from McDermott's financial results, during
the fourth quarter of 2005, B&W's revenues were $422.2 million, an
increase of $66.7 million compared to the fourth quarter of 2004. In
the 2005 fourth quarter, B&W recorded in its financial statements
Chapter 11 restructuring charges of $7.3 million and legal settlement
expenses of $7.5 million. In addition, B&W recorded domestic pension
expense of $16.8 million during the fourth quarter of 2005. In prior
years B&W's domestic pension expense was recorded in McDermott's
corporate segment. Approximately $8.0 million of B&W's fourth quarter
2005 pension expense related to an actuarial adjustment. As a result
of these expenses, B&W's operating loss for the fourth quarter of
2005, prepared in accordance with generally accepted accounting
principles, was $7.8 million. In the fourth quarter of 2004, B&W's
revenue was $355.5 million and operating income was $28.4 million,
which included no domestic pension expense.
    At December 31, 2005, B&W's backlog was $2.1 billion, compared to
backlog of $1.5 billion and $1.6 billion at December 31, 2004 and
September 30, 2005, respectively.
