ITEM 7.01.  REGULATION FD DISCLOSURE

      The Registrant hereby incorporates by reference into this Item 7.01 the
summary report of the status, as of September 6, 2005, of the offshore drilling
rigs of the Registrant attached as Exhibit 99.1, which is being furnished in
accordance with Rule 101(e)(1) under Regulation FD and shall not be deemed to be
filed.

      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, include, but are
not limited to, statements regarding the current term, start and end dates and
comments concerning future contracts and availability and other aspects of the
Registrant's drilling rigs, as well as statements concerning rigs being
upgraded, rigs reserved for upgrade and rigs under construction. 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
Registrant's overall business and financial performance can be found in the
Registrant's reports and other documents filed 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 Registrant'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 the rig status report, and the Registrant undertakes no obligation to
publicly update or revise any forward-looking statements.
