                                       2

ITEM 1.    SECURITY AND ISSUER.

           This Statement on Schedule 13D (the "Statement") relates to the
common stock, par value $1.00 per share (the "Shares"), of Michael Baker
Corporation, a Pennsylvania corporation (the "Company"). The principal executive
offices of the Company are located at Airport Office Park, Building 3, 420
Rouser Road, Coraopolis, Pennsylvania 15108.

ITEM 2.    IDENTITY AND BACKGROUND.

           This Statement is being filed by and on behalf of SEACOR SMIT Inc., a
Delaware corporation (the "Reporting Person"). The Reporting Person's principal
business includes being a provider of offshore marine services to the oil and
gas exploration and production industry, a provider of oil spill response
services to owners of tank vessels and oil storage, processing, and handling
facilities, and owner of a substantial minority equity interest in a company
that owns and operates mobile offshore jackup drilling rigs. During the last
five years, neither the Reporting Person nor, to its knowledge, any of its
executive officers or directors has: (i) been convicted in a criminal proceeding
or (ii) been a party to a civil proceeding of a judicial or administrative body
of 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
prohibiting or mandating activities subject to, federal or state securities laws
or finding any violation with respect to such laws. The Reporting Person's
business address is 11200 Richmond, Suite 400, Houston, Texas 77082.

           The name, business address, principal occupation or employment and
citizenship of each of the executive officers and directors of the Reporting
Person are set forth in Schedule A hereto.

ITEM 3.    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

           The Reporting Person purchased an aggregate of 407,800 Shares for
total consideration (including brokerage commissions) of $2,538,085 derived from
the working capital of the Reporting Person. Proceeds from 14,000 Shares sold
aggregated approximately $103,304.

ITEM 4.    PURPOSE OF THE TRANSACTION

           The Reporting Person acquired the Shares it owns for investment
purposes.

           The Reporting Person is a 67% owner of Energy Logistics, Inc., a
joint venture with Baker/M.O. Services, Inc. (a subsidiary of the Company) that
provides shorebase, marine transport, and other supply chain management services
in support of offshore exploration and production operations. The Reporting
Person may from time to time engage in other business transactions or ventures
with the Company or its affiliates.

           The Reporting Person has no plans or proposals which relate to or
that would result in any of the actions specified in clauses (a) through (j) of
Item 4 of Schedule 13D.

           Although the Reporting Person may from time to time acquire
additional Shares (subject to availability at prices deemed favorable) in the
open market, in privately negotiated transactions or otherwise, it has no
present intention to materially increase its investment in Shares. The Reporting
Person may from time to time dispose of Shares at prices deemed favorable in the
open market, in privately negotiated transactions or otherwise.


                                       3

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER

           (a) As of January 19, 2001, the Reporting Person beneficially owned
in the aggregate 393,800 Shares constituting 5.7% of the outstanding Shares. The
Reporting Person's 393,800 Shares represented 4.8% of the total number of shares
of the Company's common stock outstanding as of such date (including both Shares
and the shares of the Company's Series B Common Stock). Such computations of
percentage ownership are based upon 6,921,010 Shares outstanding and 1,306,495
shares of the Company's Series B Common Stock outstanding as of September 30,
2000, as set forth in the Company's quarterly report on Form 10-Q for the
quarterly period ended September 30, 2000.

           On the assumption that Shares and the Company's Series B Common Stock
(i.e., all of the Company's outstanding common stock) should be considered part
of a single class for purposes of determining the Reporting Person's percentage
beneficial ownership, the Reporting Person has not heretofore filed a Statement
on Schedule 13D. Assuming Shares should be considered a separate class for such
purpose, the Reporting Person became a beneficial owner of more than 5% on May
22, 2000, when it became the owner of 347,400 Shares (or 5.05% of Shares
outstanding based upon the 6,878,039 Shares outstanding on March 31, 2000 as set
forth in the Company's quarterly report on Form 10-Q for the quarterly period
ended March 31, 2000). Information is reported in this Statement based upon such
latter assumption.

           (b) The Reporting Person has the sole power to vote or direct the
vote of 393,800 Shares and the sole power to dispose or to direct the
disposition of such Shares.

           (c) Information concerning transactions in Shares by the Reporting
Person from the date that is sixty days prior to May 22, 2000 through the date
hereof is set forth in Exhibit 1 attached hereto, which is incorporated herein
by reference.

           (d) No other person is known to have the right to receive or the
power to direct the receipt of dividends from, or the proceeds from the sale of,
the Shares.

           (e) Not applicable.

ITEM 6.    CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
           RESPECT TO SECURITIES OF THE ISSUER.

           There are no contracts, arrangements, understandings or relationships
(legal or otherwise) between the Reporting Person and any other person with
respect to any securities of the Company, including but not limited to transfer
or voting of any of the securities, finder's fees, joint ventures, loan or
option arrangements, puts or calls, guarantees of profits, division of profits
or loss, or the giving or withholding of proxies.

ITEM 7.    MATERIAL TO BE FILED AS EXHIBIT

           The following Exhibit is filed herewith:

           1. Information concerning transactions in the Shares effected by the
Reporting Person from the date that is sixty days prior to May 22, 2000 through
January 19, 2001.

Statement is true, complete and correct.
