Analysis of Hydrophone Support Structure after 52-1/2 Months Exposure at a Depth of 5270 Feet in the Barking Sands Test Range, Kauai, Hawaii

摘要

The condition of the support structure for hydrophone 4-7 of the Barking Sands Test Range, Kauai, Hawaii was analyzed after 52-1/2 months of exposure to seawater at a depth of 5270 feet. The types and severity of corrosion on the various structural components are described and analyzed. A prediction of the additional lifetime to be expected from similar structures at this location is made. Recommendations for extending the useful lifetimes of similar structures at this site are made. (Author)
