          This Amendment No. 3 (the "Amendment") to the Schedule 13D is being
filed on behalf of the undersigned Reporting Persons to amend the Schedule 13D
filed with the Securities and Exchange Commission (the "Commission") on July 17,
2002 (the "Schedule 13D"), as amended by Amendment No. 1, dated September 13,
2002 ("Amendment No. 1"), and further amended by Amendment No. 2 dated March 21,
2005 ("Amendment NO. 2"), relating to shares of Common Stock, par value $0.01
per share (the "Common Stock") of Seabulk International, Inc. (the "Company").
Unless otherwise indicated, all capitalized terms used herein but not defined
herein shall have the same meanings as set forth in the Schedule 13D, Amendment
No. 1 and Amendment No. 2, as applicable.

                                       7



          Item 5. Interest in Securities of the Issuer

          The information contained in Item 5(a)-(c) and (e) of the Schedule
13D is hereby amended and restated in its entirety as follows:

          (a)-(b) the C/R Entities beneficially own no shares of Common Stock by
virtue of the conversion of its shares of Common Stock and Warrants into .2694
of a share of common stock, par value $.01 per share, of Seacor in connection
with the consummation of the merger contemplated by that certain Agreement and
Plan of Merger, dated as of March 16, 2005 among Seacor Holdings Inc.
("Seacor"), SBLK Acquisition Corp. (the "Merger Sub"), Corbulk LLC and Seabulk
International, Inc. (the "Merger"). As of the effective time of the Merger,
none of the Reporting Persons may be deemed to own any shares of Common Stock by
virtue of the fact that the C/R Entities beneficially own no shares of Common
Stock. Immediately prior to the effective time of the Merger, each of the
Reporting Persons may have been deemed to beneficially own an aggregate of
11,745,420 shares of Common Stock by virtue of the C/R Entities' ownership of
Common Stock and their ability to convert their Warrants into shares of Common
Stock.

          (c) On May 26, 2005, C/R Marine Coinvestment II, L.P. distributed
365,845 shares of its Common Stock to its sole limited partner Midstream Delta,
L.P. ("Midstream") in a liquidation of the partnership.  Midstream subsequently
sold its shares.

          (e) As of the effective time of the Merger on July 1, 2005, the
Reporting Persons ceased to be beneficial owners of any of the Company's Common
Stock.

          Item 6. Contracts, Arrangements, Understandings or Relationships With
Respect to Securities of the Issuer.

          Item 6 of Amendment No. 2 is hereby amended by adding the following at
the end thereto:

          On July 1, 2005, Merger Sub merged with and into the Company. In
connection with the Merger, effective immediately upon the effectiveness of the
Merger, each share of Common Stock of the Company automatically converted into
the right to receive .2694 shares of common stock of Seacor and $4.00 cash. In
connection with the Merger and as contemplated by the Merger Agreement,
effective immediately upon the effectiveness of the Merger, all Warrants to
purchase shares of common stock of the Company were acquired by Seacor for .2694
shares of common stock of Seacor and $3.99 cash. Immediately following the
Merger, none of the Reporting Persons are the holders of record of, or have any
pecuniary interest in any shares of Common Stock or Warrants of the Company.

          Item 7. Material to be Filed as Exhibits.

          The following exhibits are filed herewith:

          Exhibit 6A: Joint Filing Agreement, dated as of July 16, 2002
(incorporated by reference to the Schedule 13D).
