ITEM 8.01. OTHER EVENTS

      On August 30, 2005, Diamond Offshore Drilling, Inc. (the "Company") issued
a press release announcing that the jack-up drilling rig Ocean Warwick, which
had previously been listed as missing, had been located on Dauphin Island off
the coast of Alabama. The press release reported that aerial photos indicate
that the rig has sustained significant damage and is aground on the island, and
that the Company was working to get personnel to the rig but will not be able to
make a complete assessment of the condition of the unit until a crew is able to
re-board the rig. Dauphin Island is approximately 66 miles northeast of the
rig's work location on Main Pass Block 299 prior to passage of hurricane
Katrina. The Warwick is insured for approximately $50 million net of applicable
deductibles. No personnel were on board the rig at the time of the storm.

      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 concerning the location of the Company's drilling
rigs, related search efforts, insurance, condition and damage assessments,
securing the rigs, damages to the Company's drilling rigs and re-boarding the
rigs. Forward-looking statements include, without limitation, statements which
project, indicate or imply future results and may contain words like "expect,"
"intend," "plan," "will," "would," "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, potential damage to or loss of
equipment and resulting loss of contracted revenue due to hurricane Katrina, 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 further discussion of the risk factors
that could impact these areas and the Company's overall business and financial
performance can be found in the Company's reports and other filings with the
Securities and Exchange Commission.
