ITEM 8.01.  OTHER EVENTS

         On September 20, 2004, Diamond Offshore Drilling, Inc. (the "Company")
issued a press release announcing preliminary results of inspections on-board
five Company offshore drilling rigs that were operating in the path of
Hurricane Ivan, including damage to the legs and jacking system of the jack-up
drilling rig Ocean Warwick and losses of anchor chain and wire from the
semisubmersible drilling rigs Ocean Star and Ocean America. 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 apparent or potential
damage to the Company's offshore drilling rigs, movement of rigs to shipyards
or other locations, repairs and downtime, recovery efforts, future courses of
action in connection with the rigs and recommencement of operations, and other
aspects of the Company's drilling rigs. 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. A 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. These factors include, among
others, general economic and business conditions, 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.
