ITEM 1.  SECURITY AND ISSUER

          This Amendment No. 3 to Schedule 13D relates to the Common Stock, par
value $0.01 per share (the "Common Stock"), of TransMontaigne Inc., a Delaware
corporation (the "Company"). The principal executive offices of the Company are
located at 1670 Broadway, Suite 3100, Denver, Colorado 80202. Morgan Stanley
("MS"), Morgan Stanley Capital Group Inc. ("MSCGI"), Morgan Stanley & Co.
Incorporated ("MS&Co."), and Morgan Stanley DW Inc. ("MSDW", and, together with
MS, MSCGI, and MS&Co., the "Reporting Persons") hereby amend the Schedule 13D
originally filed on January 10, 2005 and amended on March 22, 2006 and April 26,
2006.

ITEM 4. PURPOSE OF TRANSACTION

          Item 4 is hereby amended by adding the following:

On May 8, 2006, MSCGI sent the following letter to the Company's board of
directors:

          [MSCGI Letterhead]

          May 8, 2006

          Mr. Donald H. Anderson
          Vice Chairman, President, and CEO
          TransMontaigne Inc.
          1670 Broadway, Ste. 3100
          Denver, CO 80202
          U.S.A.

          Dear Don:

          We are pleased to submit to you our formal binding offer for the
          acquisition of all of the outstanding shares of TransMontaigne, Inc.
          by means of a merger in which stockholders of TransMontaigne
          ("TransMontaigne") would receive $10.50 cash per TransMontaigne share.
          Our offer is not subject to any due diligence or financing condition,
          and we are not aware of any type of regulatory impediment to a
          transaction. We believe this offer, which delivers better value and
          less conditionality than the transaction with SemGroup, is clearly a
          superior proposal as contemplated by the existing merger agreement
          (the "SemGroup Agreement") by and among SemGroup, L.P., SemGroup
          Subsidiary Holding, L.L.C. ("SemGroup"), TMG Acquisition Company and
          TransMontaigne.

          This letter constitutes a binding, irrevocable offer to enter into the
          attached merger agreement, which we have signed. If by 8:00 p.m.
          Denver time on Monday, May 8, 2006 (the "Initial Expiration Time"),
          the Board of Directors of TransMontaigne has delivered to SemGroup the
          notice contemplated by Section 6.04(d)(i) of the SemGroup Agreement,
          then this offer will expire at 5:00 p.m. Denver time on Friday, May
          12, 2006 unless previously accepted by TransMontaigne by execution and
          delivery to us of the attached merger





          agreement, together with the schedules and attachments thereto. If the
          Board of Directors has not delivered such notice by the Initial
          Expiration Time, this offer will terminate at the Initial Expiration
          Time.

          This offer and our other agreements set forth in this letter shall be
          governed by and construed in accordance with the laws of the State of
          Delaware without regard to the conflicts of laws principles thereof.

          Sincerely yours,
          /s/ John Shapiro
          John Shapiro
          President
          Morgan Stanley Capital Group Inc.

The letter was accompanied by an agreement and plan of merger executed by MSCGI.
This agreement is attached hereto as Exhibit 2.

         Subsequently, on May 8, 2006, the Company informed us that it had sent
to SemGroup, L.P. the written notice contemplated under Section 6.04(d) of the
Agreement and Plan of Merger dated as of March 27, 2006, between, among others,
the Company and SemGroup, L.P., notifying SemGroup, L.P. of the Company's intent
to terminate said agreement in order to enter into an agreement with respect to
the proposal described above.

                                     * * * *

         The Reporting Persons may at any time, or from time to time, acquire
additional shares of Common Stock or dispose of their shares of Common Stock,
propose, pursue, or choose not to pursue the transaction described in the above
