Abstract:

A prototype air-supported structure, within which dehumidified air is circulated, was installed over the topsides of USS BETELGEUSE AK 260. By maintaining relative humidity of the air at approximately 35 within the air- supported structure, deterioration of topside superstructure, machinery, and other gear will be minimized. Improved corrosion prevention techniques for the preservation of shipboard machinery and gear were developed. A time-cost study comparing the current method with the new topside cover method of ship preservation has been made. Over the entire inactivationreactivation cycle, significant time savings are indicated for the topside cover procedure, especially during the ship reactivation phase. However, estimated costs of the two methods are similar. Author Modified Abstract
