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 could not
be found on its drilling location during a search by fixed-wing aircraft early
that morning. The press release indicated that the rig was located on Main Pass
Block 299, approximately 12 miles off the coast of Louisiana in about 200 ft. of
water prior to passage of hurricane Katrina, and that additional search efforts
were under way in an attempt to determine the disposition of the 300-ft.
independent cantilever rig. The Warwick is insured for approximately $50 million
net of applicable deductibles and has a book value of approximately $14 million.

      In addition, the press release indicated that the semisubmersible drilling
rig Ocean Voyager broke free from its moorings in the aftermath of hurricane
Katrina and had been located approximately 9 miles north of its pre-storm
location on Mississippi Canyon Block 711. A limited crew re-boarded the Ocean
Voyager in order to secure the unit and to further assess its condition. The
U.S. Coast Guard has been notified of both situations.

      The press release reported that the Voyager and Warwick had been secured
and personnel evacuated prior to hurricane Katrina passing through the area and
that initial fly-bys of other Company rigs in the path of hurricane Katrina did
not indicate any damage; however, the Company will not be able to make a
complete assessment of the condition of all of its rigs until personnel are able
to re-board the units over the next few days.

      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

     DIAMOND OFFSHORE REPORTS ON STATUS OF RIGS FOLLOWING HURRICANE KATRINA

Houston, Texas, August 30, 2005 -- Diamond Offshore Drilling, Inc. (NYSE:DO)
today reported that the jack-up drilling rig Ocean Warwick could not be found on
its drilling location during a search by fixed-wing aircraft early this morning.
The rig was located on Main Pass Block 299, approximately 12 miles off the coast
of Louisiana in about 200 ft. of water prior to passage of hurricane Katrina.
Additional search efforts are under way in an attempt to determine the
disposition of the 300-ft. independent cantilever rig. The Warwick is insured
for approximately $50 million net of applicable deductibles and has a book value
of approximately $14 million.

In addition, Diamond Offshore said that the semisubmersible drilling rig Ocean
Voyager broke free from its moorings in the aftermath of hurricane Katrina and
has been located approximately 9 miles north of its pre-storm location on
Mississippi Canyon Block 711. A limited crew re-boarded the Ocean Voyager this
morning in order to secure the unit and to further assess its condition. The
U.S. Coast Guard has been notified of both situations.

The Voyager and Warwick, like all Diamond Offshore conventionally moored and
jack-up rigs located in the Central and Eastern Gulf of Mexico, had been secured
and personnel evacuated prior to hurricane Katrina passing through the area.
Initial fly-bys of other Company rigs in the path of hurricane Katrina have not
indicated any damage. However, Diamond Offshore will not be able to make a
complete assessment of the condition of all of its rigs until personnel are able
to re-board the units over the next few days.

Diamond Offshore provides contract drilling services to the energy industry
around the globe and is a leader in deepwater drilling.
