This Amendment No. 4 to the statement on Schedule 13D (this “Amendment No. 4”) amends the statement originally filed on February 26, 2007 (as amended by Amendment No. 1 thereto filed on March 18, 2009, Amendment No. 2 thereto filed on May 19, 2009 and Amendment No. 3 thereto filed on December 20, 2010, the “Schedule 13D”) by EW Transportation LLC, a Delaware limited liability company (“EW LLC”), Park Avenue Transportation Inc., a Delaware corporation (“PAT”), and Brian P. Friedman (“Friedman”).

Capitalized terms used but not defined in this Amendment No. 3 have the meanings ascribed to them in the Schedule 13D.

Item 4.

Purpose of Transaction.

Item 4 of the Schedule 13D is hereby supplemented as follows:

On March 13, 2011, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among Kirby Corporation, a Nevada corporation (“Parent”), KSP Holding Sub, LLC, a Delaware limited liability company and direct wholly owned subsidiary of Parent (“Holding Sub”), KSP LP Sub, LLC, a Delaware limited liability company and direct wholly owned subsidiary of Parent (“LP Sub”), KSP Merger Sub, LLC, a Delaware limited liability company wholly owned by Holding Sub and LP Sub (“Merger Sub,” and together with Parent, Holding Sub and LP Sub, the “Parent Parties”), the Issuer, K-Sea General Partner L.P., a Delaware limited partnership that is the sole general partner of the Issuer (the “General Partner”), and K-Sea General Partner GP LLC, a Delaware limited liability company that is the sole general partner of the General Partner (“KSP GP,” and together with the Issuer and the General Partner, the “Company Parties”), pursuant to which, among other things, Merger Sub will merge with and into the Issuer (the “Merger”), with the Issuer as the surviving entity, and each Company Equity Interest (as defined in the Merger Agreement) will be converted into the right to receive the merger consideration specified therein.

On March 13, 2011, EW LLC entered into a Support Agreement (the “Support Agreement”) with the Parent Parties, pursuant to which, among other things, it agreed to vote the Common Units held by it in favor of the Merger and against any proposal made in opposition to the Merger, and it granted an irrevocable proxy to Parent, coupled with an interest. EW LLC also agreed that, during the duration of the Support Agreement, it will not (i) Transfer (as such term is defined in the Support Agreement) any of its Common Units or any right or interest therein; (ii) enter into any agreement, arrangement or understanding that could violate or conflict with its representations, warranties, covenants and obligations under the Support Agreement; (iii) take any action that could restrict its legal power and authority to comply with and perform its covenants and obligations under the Support Agreement; or (iv) discuss, negotiate or enter into any contract or other arrangement with respect to any matter related to the Support Agreement; provided, however, that EW LLC may Transfer any or all of its Common Units to any of its affiliates if such transferee affiliate agrees in writing to be bound by the terms of the Support Agreement and to hold such Common Units subject to all terms of the Support Agreement, in each case, as if it were EW LLC. EW LLC agreed not to, directly or indirectly, solicit or have any discussion regarding an acquisition proposal with respect to the Issuer. EW LLC made certain customary representations and warranties to the Parent Parties in the Support Agreement. The Support Agreement will remain in effect until the earliest to occur of (a) the effective time of the Merger, (b) the termination of the Merger Agreement, (c) the date of any modification, amendment or waiver of the Merger Agreement that adversely affects EW LLC, (d) a change in recommendation in respect of the Merger by the board of directors of the Issuer, and (e) the written agreement of EW LLC and Parent to terminate the Support Agreement. Each of the wholly owned subsidiaries of EW LLC that own Common Units (which Common Units are included in the amounts reported on the cover pages hereto) entered into substantially identical support agreements with the Parent Parties on March 13, 2011 (together with the Support Agreement, the “EW Support Agreements”).

References to, and descriptions of, each of the Merger Agreement and the EW Support Agreements as set forth in or incorporated into this Item 4 are qualified in their entirety by reference to the

copies of each such agreement filed as an exhibit to this Schedule 13D, each of which is incorporated in its entirety in this Item 4.
