Item 2.01.    Completion of Acquisition or Disposition of Assets.

       On July 1, 2005, pursuant to the Agreement and Plan of Merger (the
"Merger Agreement"), dated as of March 16, 2005, among SEACOR Holdings Inc.
("SEACOR"), SBLK Acquisition Corp., CORBULK LLC, and Seabulk International, Inc.
("Seabulk"), SBLK Acquisition Corp. (a wholly-owned subsidiary of SEACOR) merged
with and into Seabulk (the "Merger"). As a result of the Merger, Seabulk will
now operate as a wholly-owned subsidiary SEACOR.

       Pursuant to the Merger Agreement, each outstanding share of common stock
of Seabulk was converted into 0.2694 of a share of SEACOR common stock and $4.00
in cash. Based on SEACOR's closing price of $64.30 on June 30, 2005, Seabulk
stockholders will receive approximately $21.32 in SEACOR stock and cash for each
outstanding share of Seabulk.

       SEACOR funded the cash portion of the purchase price with cash on hand
and cash drawn down from its existing revolving credit facility with DnB NOR
Bank ASA.

       SEACOR's common stock will continue to trade on the New York Stock
Exchange under the symbol "CKH". Seabulk common stock has been delisted from the
Nasdaq National Market and Seabulk has filed a Form 15 with the Securities and
Exchange Commission to terminate the registration of Seabulk common stock under
the Securities Exchange Act of 1934, as amended.

       On July 1, 2005, SEACOR and Seabulk issued a joint press release
announcing the completion of the Merger. A copy of the press release is attached
hereto as Exhibit 99.1 and is incorporated herein by reference.
