The Post and Courier of Charleston reports that an environmental study of the 888-foot ship must be completed before any repair can begin. A report is expected by January.
Patriots Point Executive Director Mac Burdette believes it will cost about $6 million to clean compartments of any chemicals and liquids.
No money has been budgeted for repairs, and most of the work likely will be a decade away. The aging warship has been docked at Patriots Point since 1975.
Repair estimates include about $20 million in hull work. Other major costs include $10 million to replace the pier, $6 million to paint the Yorktowns exterior and $5 million to replace the flight deck.
