         (c) Exhibits

             Exhibit 99.1       Noble Corporation and Subsidiaries Fleet Status
                                Update as of April 17, 2003.


ITEM 9.  REGULATION FD DISCLOSURE.

         The Registrant hereby incorporates by reference into this Item 9 the
Noble Corporation and Subsidiaries Fleet Status Update as of April 17, 2003 of
the Registrant, which is attached as Exhibit 99.1 and will be published on the
Registrant's web site at http://www.noblecorp.com. The report provides certain
summary information about the operations of the drilling units of the
Registrant. The report is being furnished in accordance with Rule 101 (e) (1)
under Regulation FD and shall not be deemed to be filed.

         The Noble Corporation and Subsidiaries Fleet Status Update as of April
17, 2003 contains forward-looking statements about the Registrant's business,
financial condition and prospects. The Registrant's actual results could differ
materially from those indicated by the forward-looking statements because of
various risks and uncertainties, including, without limitation, changes in
United States tax laws, or the enactment of new United States tax laws, that may
result in the Registrant being subject to taxation in the United States on its
worldwide earnings, other material changes in the tax laws of the United States
or other countries in which the Registrant operates which could increase its
effective tax rate, volatility in crude oil and natural gas prices, the
discovery of significant additional oil and/or gas reserves or the construction
of significant oil and/or gas delivery or storage systems that impact regional
or worldwide energy markets, potential deterioration in the demand for the
drilling services of the Registrant and resulting declining dayrates, changes in
customers' drilling programs or budgets due to factors discussed herein or due
to their own internal corporate events, the cancellation by customers of
drilling contracts or letter agreements or letters of intent for drilling
contracts or their exercise of early termination provisions generally found in
the Registrant's drilling contracts, intense competition in the drilling
industry, changes in oil and gas drilling technology or in competitors' drilling
rig fleets that could make the Registrant's drilling rigs less competitive or
require major capital investment to keep them competitive, political and
economic conditions in the United States and in international markets where the
Registrant operates, acts of war or terrorism and the aftermath of the September
11, 2001 terrorist attacks on the United States, cost overruns or delays on
shipyard repair, maintenance, conversion or upgrade projects, adverse weather
(such as hurricanes or monsoons) and seas, operational risks (such as blowouts
and fires), limitations on the Registrant's insurance coverage, and requirements
and potential liability imposed by governmental regulation of the drilling
industry (including environmental regulation). All of the foregoing risks and
uncertainties are beyond the Registrant's ability to control, and in many cases,
the Registrant cannot predict the risks and uncertainties that could cause its
actual results to differ materially from those indicated by the forward-looking
statements. When used in the report, the words "believes", "anticipates",
"expects", "plans" and similar expressions as they relate to the Registrant or
its management are intended to identify forward-looking statements.
