Issuable upon Conversion of the Debentures

     This prospectus supplement relates to $325,000,000 aggregate principal amount of 2.75% Senior Convertible Debentures due 2027 (the “Debentures”) of Global Industries, Ltd. and the shares of our common stock, par value $0.01 per share, issuable upon conversion of such Debentures. We issued and sold the Debentures in a private placement on July 27, 2007. This prospectus supplement will be used by the selling security holders to resell the Debentures and the shares of common stock issuable upon conversion of the Debentures. We will not sell any securities under this prospectus supplement or receive any of the proceeds from the sale of the Debentures or the shares of common stock issuable upon conversion of the Debentures. Our common stock is listed on The Nasdaq Global Select Market under the symbol “GLBL.” The last reported sale price of our common stock on May 5, 2008 was $16.93 per share.

     This prospectus supplement supplements the prospectus dated October 31, 2007 (the “prospectus”), as supplemented by the prospectus supplements dated December 5, 2007, January 7, 2008, February 5, 2008, March 5, 2008 and April 4, 2008.

This prospectus supplement is qualified by reference to the prospectus, except to the extent that the information provided by this prospectus supplement supersedes or supplements certain information contained in the prospectus.

     Investing in the Debentures and shares of our common stock issuable upon conversion of the Debentures involves risks that are described in the “Risk Factors” section beginning on page 6 of the prospectus and the risk factors incorporated therein by reference from our annual and quarterly reports filed with the Securities and Exchange Commission.

SELLING SECURITY HOLDERS

     The information in the prospectus in the table under the caption “Selling Security Holders” is amended by:

	•		adding the information in the “Additional Selling Security Holders” table below regarding the selling security holder listed therein.

     The information set forth below is based on information previously provided by or on behalf of the selling security holders. Information concerning the selling security holders may change from time to time. The selling security holders may from time to time offer and sell any or all of the securities under the prospectus (as amended and supplemented hereby). Because the selling security holders are not obligated to sell the Debentures or any shares of common stock issuable upon conversion of the Debentures, we cannot estimate the amount of the Debentures or how many shares of common stock that the selling security holders will hold upon consummation of any such sales. In addition, since the date on which a selling security holder provided this information to us, such selling security holder may have sold, transferred or otherwise disposed of all or a portion of its Debentures or common shares issuable upon conversion of its Debentures.

     Unless described in the prospectus under the caption “Selling Security Holders” (as amended and supplemented hereby), based upon information previously provided by the selling security holders, the selling security holders do not beneficially own in excess of 1% of our outstanding common stock.

     Except as noted in the prospectus under the caption “Selling Security Holders” (as amended and supplemented hereby), based upon the information previously provided by the selling security holders, none of the selling security holders nor any of their affiliates, officers, directors or principal equity holders has held any position or office or has had any material relationship with us within the past three years.

     The following table is based solely on information provided by the selling security holder listed below. This information represents the most current information provided to us by such selling security holder.
