         This Amendment No. 3 to the statement on Schedule 13D originally filed
on January 8, 2001, as amended on February 8, 2001 and July 2, 2003 (the
"Statement"), is filed by First Reserve Fund VIII, L.P. ("Fund VIII"), First
Reserve GP VIII, L.P. ("GP VIII"), and First Reserve Corporation ("First
Reserve," and together with the Funds, the "Reporting Persons") and relates to
the Common Stock, par value Euro 0.01 per share (the "Common Stock"), of Chicago
Bridge & Iron Company N.V., a Company organized under the laws of the
Netherlands (the "Issuer" or "CB&I"). That Schedule 13D is hereby amended as set
forth below.

ITEM 4.  PURPOSE OF TRANSACTION.
         ----------------------

         The text of Item 4 of the Statement is hereby amended by adding the
following:

         On July 10, 2003, the Underwriters purchased 1,288,881 shares of Common
Stock (the "Over-Allotment Shares") pursuant to the Over-Allotment Option. The
Over-Allotment Shares were sold by Fund VIII to the Underwriters at a price of
$20.662. The Underwriters resold the Over-Allotment Shares to the public at
$21.75 per share.

         A registration statement relating to the Over-Allotment Shares has been
filed with the Securities and Exchange Commission and has been declared
effective. This Amendment Number 3 to Schedule 13D shall not constitute an offer
to sell or the solicitation of an offer to buy nor shall there be any sale of
the Over-Allotment Shares in any state in which such offer, solicitation or sale
would be unlawful prior to registration or qualification under the securities
laws of such state. The offering is being made only by means of a prospectus. A
written prospectus meeting the requirements of Section 10 of the Securities Act
of 1933 may be obtained, when available, from Credit Suisse First Boston
Corporation at Eleven Madison Avenue, Prospectus Department, New York, New York,
10010-3629.
