      This Amendment No. 5 to the statement on Schedule 13D, originally filed on
January 8, 2001 and amended on February 14, 2001, December 10, 2001, March 6,
2002 and March 15, 2002 (the "Original Statement"), is filed by WEDGE
Engineering B.V., a Netherlands company ("WEDGE Engineering"), and Issam M.
Fares and relates to the Common Stock, par value NLG .01 per share (the "Common
Stock"), of Chicago Bridge & Iron Company N.V., a Company organized under the
laws of the Netherlands ("Issuer"), to supplement certain information set forth
the Original Statement. Unless amended or restated, the Original Statement
remains in effect. Unless otherwise indicated, each capitalized term used but
not defined herein shall have the meaning assigned to such term in the Original
Statement.

ITEM 4. PURPOSE OF TRANSACTION.

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

      On April 25, 2002, the Issuer filed a Registration Statement on Form S-3
(Registration No. 333-86960) relating to the proposed offering and sale of up to
2,000,000 shares of its Common Stock by WEDGE Engineering in an underwritten
public offering pursuant to the exercise by WEDGE Engineering of one demand
right under the Shareholder Agreement as requested by the Issuer.

      A registration statement relating to these securities has been filed with
the Securities and Exchange Commission but has not yet become effective. These
securities may not be sold nor may offers to buy be accepted prior to the time
the registration statement becomes effective. This Amendment No. 5 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 these securities in any State in which such
offer, solicitation or sale would be unlawful prior to registration or
qualification under the securities laws of any such State. The lead manager of
the offering will be Credit Suisse First Boston. Co-managers will be Bear
Stearns & Co. Inc. and Lehman Brothers. The offering will be 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 at Eleven Madison Avenue, Prospectus Department, New York, New
York, 10010-3629.

                                       4

                                    SIGNATURE

      After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this Statement is true, complete and
correct.

      Dated:  May 2, 2002.
