                         AMENDMENT NO. 2 TO SCHEDULE 13D

     This Amendment No. 2 on Schedule 13D/A ("Amendment No. 2") to the Statement
on Schedule 13D ("Schedule 13D") is filed on behalf of each of (i) Shell US Gas
& Power LLC, formerly Coral Energy, LLC ("Shell Gas & Power") as the direct
beneficial owner of Common Units and Class A Special Units and (ii) by virtue of
their respective direct holdings of securities of Shell Gas & Power (as
described below on this statement) by Shell Oil Company ("Shell Oil"), SWEPI LP
("SWEPI"), Shell Gas Pipeline Corp. #2 ("Shell Pipeline"), Shell Gas Gathering
Corp. #2 ("Shell Gathering") and Shell Seahorse Company ("Shell Seahorse")
(collectively, the "Reporting Entities").

     This Amendment No. 2 is filed to reflect (i) the issuance on August 2, 2001
by Enterprise Products Partners L.P. of an additional 3,000,000 Class A Special
Units pursuant to the Partnership Agreement and (ii) the conversion of 5,000,000
Class A Special Units into 5,000,000 Common Units effective as of August 2,
2001.

     Unless otherwise indicated, each capitalized term used but not otherwise
defined herein shall have the meaning assigned to such term in the Schedule 13D.

Item 1.   Security and Issuer. No change to this Item.

Item 2.   Identity and Background. Paragraph 2 in subsection (a) of this Item is
          deleted in its entirety and replaced with the following:

               Shell Gas & Power is the beneficial holder of approximately 31.1%
          of the outstanding Common Units of the Issuer. Shell Oil, SWEPI, Shell
          Pipeline, Shell Gathering and Shell Seahorse are the holders of 100%
          of the common membership interests, and approximately 2.33%, 17.14%,
          58.45%, 16.38% and 5.7%, respectively, of the total ownership
          interests, in Shell Gas & Power. Each of SWEPI, Shell Pipeline, Shell
          Gathering and Shell Seahorse is an indirect, wholly owned subsidiary
          of Shell Oil. Together, Shell Oil, SWEPI, Shell Pipeline, Shell
          Gathering and Shell Seahorse may be deemed to control Shell Gas &
          Power.

Item 3.   Source and Amount of Funds or Other Consideration

          Item 3 is hereby supplemented with the following information:

               Under the terms of the Second Amended and Restated Agreement of
          Limited Partnership of the Enterprise Products Partners L.P. (the
          "Partnership Agreement"), on August 2, 2001 Shell Gas & Power obtained
          from the Issuer 3,000,000 Units.

Item 4.   Purpose of Transaction

          Item 4 is hereby deleted in its entirety and replaced with the
          following:

               The transactions described in Item 3 above occurred as a result
          of negotiations with the Issuer. The Units were acquired for
          investment purposes. Shell Gas & Power intends to review its
          investment in the Issuer on an ongoing basis and, depending upon the
          price of, and other market conditions relating to, the Units,
          subsequent developments affecting the Issuer, the Issuer's business
          and prospects, other investment and business opportunities available
          to Shell Gas & Power, general stock market and economic conditions,
          tax considerations and other factors deemed relevant, may decide to
          increase or decrease the size of its investment in the Issuer.

               Other than as described in Item 3 and Item 6 hereof, none of the
          Reporting Entities (nor, to their knowledge, any person listed on
          Appendix A hereto) has any plan or proposal that would result in any
          of the consequences listed in paragraph (a) - (j) of Item 4 of
          Schedule 13D.

Item 5.   Interest in Securities of the Issuer

          subordinated units outstanding as of July 1, 2001. The Reporting
          Entities are deemed to be the beneficial owners of 6,000,000 Common
          Units and 14,500,000 Units, which are convertible into Common Units
          under the terms of the Partnership Agreement during the period between
          August 1, 2001 and August 1, 2003. The Units do not accrue
          distributions and are not entitled to cash distributions until their
          conversion into Common Units. The Common Units and the Units represent
          a 31.1% equity interest in the Issuer.

               (b) As described in Item 2(a), each of the Reporting Entities may
          be deemed to share voting power and investment power with respect to
          the Units.

               (c) Except for the issuance of the 3,000,000 Units and the
          conversion of 5,000,000 Units into Common Units, none of the Reporting
          Entities, nor, to the best of their knowledge, any person listed on
          Appendix A hereto, has effected any transactions in the Units during
          the past 60 days.

               (d) None of the Reporting Entities, nor, to the best of their
          knowledge, any person listed in Appendix A beneficially owns any Units
          of the Issuer except as set forth above. Except as disclosed above to
          the best of the knowledge of each Reporting Entity, no persons other
          than the Reporting Entities have the right to receive or the power to
          direct the receipt of dividends from, or the proceeds from the sale
          of, the Units beneficially owned by the Reporting Entities.

               (e) Not applicable.
