                          DEREGISTRATION OF SECURITIES

Chicago Bridge & Iron Company N.V., a Netherlands company ("CB&I"), filed a
Registration Statement on Form S-3 (Registration No. 333-70760) (the
"Registration Statement") with the Securities and Exchange Commission (the
"SEC") on October 2, 2001, registering 1,307,356 shares of CB&I's common stock
(or 2,614,712 shares taking into account the 2-for-1 stock split effective in
February 2003) to be offered from time to time by the selling shareholders named
therein (the "Offering"). CB&I subsequently filed a Pre-Effective Amendment
No. 1 on November 1, 2001 pertaining to the same Offering and constituting part
of the Registration Statement. The SEC declared the Registration Statement
effective on November 9, 2001.

The Offering contemplated by the Registration Statement has terminated by virtue
of the expiration of CB&I's contractual obligation to the remaining selling
shareholders to maintain the effectiveness of the Registration Statement.
Pursuant to the undertaking contained in the Registration Statement, CB&I is
filing this post-effective amendment to remove from registration all of the
shares that were registered in the Offering but remain unsold as of the date
hereof. As of the date hereof, there are 675,400 shares of common stock (taking
into account the 2-for-1 stock split effective in February 2003) that remain
unsold under the Registration Statement.

Accordingly, CB&I files this post-effective amendment to deregister the 675,400
shares of its common stock covered by the Registration Statement that remain
unsold as of the date hereof.

         Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Amendment
No. 1 to Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in The Woodlands, State of Texas, on April 4, 2003.
