Schedule 13D

Item 1.  Security and Issuer


This statement relates to the Common Stock, par value $0.01 (the "Common
Stock"), of GulfMark Offshore, Inc., a Delaware corporation ("GulfMark
Offshore"). The address of the principal executive offices of GulfMark Offshore
is 4400 Post Oak Parkway, Suite 1170, Houston, Texas 77027-3414.


Item 2.  Identity and Background


This  statement is filed on behalf of Lehman  Brothers  Holdings  Inc., a
Delaware  corporation  ("Holdings"),  745 Seventh Avenue, New York, New York
10019.


Holdings is one of the leading global investment banks, serving institutional,
corporate, government and high-net-worth clients and customers.


The names, residence or business addresses, citizenships and present principal
occupations or employment of the senior executive officers and directors of
Holdings are set forth in Appendix A hereto.

Holdings is the managing partner of Shearson Oil Services Partners ("SOS
Partners"), a partnership formed in 1989 to hold, among other things, shares of
common stock of Gulfmark International, Inc. ("Gulfmark International"), from
which GulfMark Offshore was spun off in 1997, and which holds the shares of
Common Stock reported herein. Holdings contributed 100% of the capital of SOS
Partners. David J. Butters and Robert B. Millard, the other partners of SOS
Partners, are each entitled to receive 5.625% of the profits of SOS Partners
after Holdings has received distributions equal to its capital investment plus a
return on its capital equal to its cost of funds.

Messrs. Butters and Millard, each of whom are U.S. citizens, are directors of
GulfMark Offshore and are Managing Directors of Lehman Brothers Inc., a direct,
wholly-owned subsidiary of Holdings.

Neither the Reporting Person nor, to the best knowledge of the Reporting Person,
either of Messrs. Butters or Millard or any of the persons listed in Appendix A
hereto has during the last five years (i) been convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) or (ii) been
party to a civil proceeding of a judicial or administrative body of a competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or mandating activities
subject to, federal or state securities laws or finding any violation with
respect to such laws.


Item 3.  Source of Funds or Other Consideration

No change.

Item 4.  Purpose of Transaction


No change.

The Reporting Person intends to evaluate continually the business, prospects and
financial condition of GulfMark Offshore, the market for shares of Common Stock,
other opportunities available to the Reporting Person, general economic
conditions, money and stock market conditions and other factors and future
developments which the Reporting Person may deem relevant from time to time.
Depending on these factors, the Reporting Person may decide to sell all or part
of the Common Stock that it holds. Any disposition, or any further acquisition,
may be effected through privately negotiated transactions, donations to
charitable organizations or otherwise.

Except as set forth in this Report, as amended, the Reporting Person does not
have any specific plans or proposals that relate to or would result in any of
the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D.


Item 5.  Interest in Securities of the Issuer


On June 30, 2002, Gulfmark Offshore effected a two-for-one common stock split.
Since the filing of the Reporting Person's Amendment No.2 to Schedule 13D on
March 18, 2002, there has been no other change to the amount of the Common Stock
beneficially owned by the Reporting Person, except as set forth in paragraph (c)
below. Percentages are based on 20,042,519 shares of Common Stock outstanding as

on Form 10-Q.

     may each be deemed to beneficially own the shares of Common Stock held by
     SOS Partners; however, each of them disclaims beneficial ownership of such
     shares except to the extent of his pecuniary interest therein.

(b)  See cover page. As partners of SOS Partners, Messrs. Butters and Millard
     may each be deemed to share with Holdings and each other the power to vote
     or direct the vote or to dispose or direct the disposition of the shares of
     Common Stock held by SOS Partners; however, each of them disclaims
     beneficial ownership of such shares except to the extent of his pecuniary
     interest therein.

(c)  On May 14, 2004, SOS Partners made a distribution of 200,000 shares of the
     Common Stock to its partners as follows:

            Holdings                                             177,500
            David J. Butters                                     11,250
            Robert B. Millard                                    11,250

     On May 14, 2004, Holdings donated the 177,500 shares of Common Stock
     received in the distribution to The Lehman Brothers Foundation (the
     "Foundation"), a tax-exempt private foundation under Section 501(c)(3) of
     Internal Revenue Code. The Foundation has informed Holdings that it
     currently intends to sell all of such shares pursuant to Rule 144 under the
