                          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.

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

undersigned, thereunto duly authorized, in The Woodlands, State of Texas, on
