Nature Of Operations And Accounting Policies [Abstract]

Basis Of Consolidation

The condensed consolidated financial information for the three and six months ended June 30, 2012 and 2011 has been prepared by the Company and has not been audited by its independent registered public accounting firm. The condensed consolidated financial statements include the accounts of SEACOR Holdings Inc. and its consolidated subsidiaries. In the opinion of management, all adjustments (consisting of normal recurring adjustments) have been made to fairly present the Company’s financial position as of June 30, 2012, its results of operations for the three and six months ended June 30, 2012 and 2011, its comprehensive income for the three and six months ended June 30, 2012 and 2011, its changes in equity for the six months ended June 30, 2012, and its cash flows for the six months ended June 30, 2012 and 2011. Results of operations for the interim periods presented are not necessarily indicative of operating results for the full year or any future periods.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

Unless the context otherwise indicates, any reference in this Quarterly Report on Form 10-Q to the “Company” refers to SEACOR Holdings Inc. and its consolidated subsidiaries and any reference in this Quarterly Report on Form 10-Q to “SEACOR” refers to SEACOR Holdings Inc.

Discontinued Operations, Policy

Discontinued Operations. The Company's Environmental Services business segment was conducted through SEACOR Environmental Services Inc. ("SES") and O'Brien's Response Management Inc. ("ORM"). SES included National Response Corporation, one of the largest providers of oil spill response services in the United States; NRC Environmental Services Inc., a leading provider of environmental and industrial services on the West Coast of the United States; SEACOR Response Ltd., which provides oil spill response and emergency response services to customers in international markets; and certain other subsidiaries (collectively the "SES Business"). On March 16, 2012, the Company sold the SES Business for a net sales price of $99.9 million and recognized a gain of $20.8 million, net of tax, or $1.00 per diluted share. The transaction did not include ORM, a leading provider of crisis and emergency preparedness and response services. The Company has no continuing involvement in the SES Business, although the sales agreement provides that the Company may receive contingent consideration equal to a portion of the revenue generated by any extraordinary oil spill response that occurs within three years following the date of sale. For all periods presented, the Company has reported the financial position, results of operations and cash flows for the SES Business as discontinued operations in the accompanying condensed consolidated financial statements. The remaining ORM business in the segment was renamed Emergency and Crisis Services.

Revenue Recognition

Revenue Recognition. The Company recognizes revenue when it is realized or realizable and earned. Revenue is realized or realizable and earned when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price to the buyer is fixed or determinable, and collectability is reasonably assured. Revenue that does not meet these criteria is deferred until the criteria are met. Deferred revenues, included in other current liabilities, for the six months ended June 30 were as follows (in thousands):

	2012			2011
Balance at beginning of period	$	9,968		$	21,045
Revenues deferred during the period	13,550			3,978
Revenues recognized during the period	(7,697		)	(8,334		)
Balance at end of period	$	15,821		$	16,689

As of June 30, 2012, deferred revenues included $6.4 million relating to the time charter of several offshore support vessels operating in the U.S. Gulf of Mexico that are scheduled to be paid through the conveyance of a limited net profit interest in developmental oil and gas producing properties owned by a customer. Payments from the conveyance of the limited net profit interest, and the timing of such payments, are contingent upon production and energy sale prices. Based on the current production payout estimate, the deferred revenues are expected to be paid in 2012. The Company will continue to recognize revenues as cash is received or earlier should future payments become determinable. All costs and expenses related to these charters were recognized as incurred.

As of June 30, 2012, deferred revenues included $7.3 million related to contract-lease revenues for certain helicopters leased by Aviation Services to Aeroleo Taxi Aero S/A ("Aeroleo"), its Brazilian joint venture (see Note 6). The deferral resulted from difficulties experienced by Aeroleo following one of its customer's cancellation of certain contracts for a number of AW139 aircraft under contract-lease from Aviation Services. The Company will recognize revenues as cash is received or earlier should future collectability become reasonably assured. All costs and expenses related to these contract-leases were recognized as incurred.

As of June 30, 2012, deferred revenues also included $2.0 million related to contract-lease revenues for certain helicopters leased by Aviation Services to one of its customers. The deferral resulted from the customer having its operating certificate revoked for a period of time and therefore being unable to operate. The certificate has since been reinstated but uncertainty still remains regarding the collectability of the contract-lease revenues. The Company will recognize revenues as cash is received or earlier should future collectability become reasonably assured. All costs and expenses related to these contract-leases were recognized as incurred.
