Technical note Feb-Oct 1973

Pagination or Media Count:
Information on the corrosion of materials exposed to marine environments must be obtained if ocean structures are to be designed with predictable lifetimes. A large amount of relevant information can be obtained at a relatively low cost by evaluating the condition of objects retrieved from the sea. To optimize these evaluations, they must be performed logically and uniformly. Development and application of guidelines for such evaluations can provide this optimization. As a part of the development of guidelines, this report describes an evaluation of the AUTEC acoustic array emplaced in 1962 and retrieved from the Tongue-of-the-Ocean, Bahama Islands, after 12 years of exposure. The condition of the array as well as the application and revision of the inspection guidelines are discussed.
