ITEM 1.  SECURITY AND ISSUER

     This Amendment No. 4 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, April 26,
2006, May 8, 2006, and May 17, 2006.

ITEM 4. PURPOSE OF TRANSACTION

      Item 4 is hereby amended by adding the following:

On June 18, 2006, MSCGI sent the following letter to the Company's board of
directors:

       [MSCGI Letterhead]

       June 18, 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 offer $11.35 cash per share for the acquisition of all
       of the outstanding shares of TransMontaigne Inc. ("TransMontaigne"),
       pursuant to the attached executed merger agreement. We believe that this
       offer will deliver better value with greater speed and certainty than
       your current proposed transaction, and that it is a superior proposal as
       contemplated by the amended and restated merger agreement (the "SemGroup
       Agreement") by and among SemGroup, L.P., SemGroup Subsidiary Holding,
       L.L.C. ("SemGroup"), TMG Acquisition Company and TransMontaigne.

       In particular, we note that SemGroup has received a second request from
       the Federal Trade Commission. We do not expect to have any such delay. As
       you observed in your preliminary proxy statement, "a merger agreement
       with Morgan Stanley would not likely result in the receipt of a second
       request for additional information from the FTC." Thus, we think it is
       clear to all parties that our proposal has far greater certainty of
       success.

       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, June 19, 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 7:00 a.m. Denver time on Friday, June 23, 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.

                                          * * * *

      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
letter; change the terms of the transaction described in the above letter,
including the price, conditions, or scope of the transaction; take any action in
or out of the ordinary course of business to facilitate or increase the
likelihood of consummation of the transaction described in the above letter;
otherwise seek control or seek to influence the management and policies of the
Company; or change their intentions with respect to any such matters. In
connection with the proposed transaction, the Reporting Persons are considering
other transactions with respect to the Company and its assets, including without
limitation financing transactions, partnerships with third parties, or sales of
assets to the Company's affiliated master limited partnership or third parties.
