Abstract:

The condition of the support structure for hydrophone 4-7 of the Barking Sands Test Range, Kauai, Hawaii was analyzed after 52-12 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.
