ITEM 8.01.  OTHER EVENTS

         On July 18, 2005, Diamond Offshore Drilling, Inc. (the "Company")
issued a press release announcing that the Board of Directors of the Company has
declared a quarterly cash dividend of $0.125 per common share, payable on
September 1, 2005 to shareholders of record on August 1, 2005. The dividend
represents a doubling of the Company's quarterly dividend. The press release
also discuses the Company's belief that its financial position is strong and
that its earnings outlook is positive, and as a result, that the Company's Board
of Directors will in the future consider declaring a special cash dividend in
the first quarter of 2006. The amount of the special cash dividend, if any, will
be determined by the Board of Directors based upon the Company's financial
position, earnings outlook, capital spending plans, and such other factors as
the Board of Directors considers relevant. The Board of Directors may also
consider paying annual special dividends in future years, if it believes that
the Company's financial position, earnings outlook, capital spending plans and
other relevant factors warrant such action at such time.

         Filed herewith is a copy of such press release.

         Statements in this report that contain "forward-looking statements"
within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended, may include, but
are not limited to, statements regarding positive earnings expectations.
Forward-looking statements include, without limitation, statements which
project, indicate or imply future results or future actions and may contain
words like "consider," "expect," "intend," "plan," "will," "estimated" and
"budgeted," among others. Such statements are inherently subject to a variety of
risks and uncertainties that could cause actual results to differ materially
from those anticipated or projected. These factors include, among others, the
risk that the current favorable business outlook may change due to factors such
as: the present favorable markets for the Company's services will not be
maintained or may not continue to improve, as well as general economic and
business conditions, changes in oil and natural gas prices, casualty losses,
industry fleet capacity, changes in foreign and domestic oil and gas exploration
and production activity, competition, changes in foreign, political, social and
economic conditions, regulatory initiatives and compliance with governmental
regulations, customer preferences and various other matters, many of which are
beyond the Company's control. Given these concerns, investors and analysts
should not place undue reliance on forward-looking statements. Each
forward-looking statement speaks only as of the date of this report. The Company
expressly disclaims any obligation or undertaking to release publicly any
updates or revisions to any forward-looking statement to reflect any change in
the Company's expectations with regard thereto or any change in events,
conditions or circumstances on which any forward-looking statement is based. A

Company's overall business and financial performance can be found in the
Company's reports and other filings with the Securities and Exchange Commission.
