Item 1.01     Entry Into a Material Definitive Agreement

         On May 3, 2006, the Compensation Committee of our Board of Directors
(the "Committee") approved the form of grant agreements to be used in connection
with grants of performance shares to our executive officers and key employees
and grants of restricted stock to our nonemployee directors pursuant to our 2001
Directors and Officers Long-Term Incentive Plan, as amended to date ("2001
LTIP"). A copy of the general form of agreements for grants of restricted stock
and performance shares under the 2001 LTIP are included as exhibits 10.1 through
10.2 to this report and are incorporated herein by reference. The 2001 LTIP has
been previously filed as Appendix B to McDermott's Proxy Statement for its
Annual Meeting of Stockholders held on May 3, 2006.

Item 5.02     Departure of Directors or Principal Officers; Election of
              Directors; Appointment of Principal Officers.

       (b)    On May 3, 2006, Mr. Joe B. Foster retired from the Board of
              Directors of McDermott International, Inc. ("McDermott") after
              more than seven years of service. At the time of his retirement,
              Mr. Foster served on the Audit and Special Finance Committees.

Item 5.03     Amendments to Articles of Incorporation or Bylaws; Change in
              Fiscal Year.

         Our Board of Directors amended Article II, Section 7 of our By-Laws,
effective May 3, 2006, to provide that (1) beginning with our 2006 annual
meeting of stockholders, a person shall not be nominated for election to our
Board of Directors if such person shall have attained the age of 72 prior to the
date of election and (2) any director elected at or after that meeting who
attains the age of 72 during his or her term shall be deemed to have resigned
and retired at the first annual meeting of stockholders immediately following
the person's attainment of the age of 72.

         Previously, our By-Laws provided for a similar mandatory retirement
provision based upon the attainment of the age of 70 and granting the Board of
Directors the ability to waive the deemed retirement provision for one year.
