Corrosion Control of Inter-Hull Spaces

摘要

The report expands upon the work conducted by the Naval Sea Systems Command todevelop a tank preservation protocol which is intended to achieve a service life of 15 to 20 years. This report focuses on controlling corrosion in the region between the inner and outer hulls in new double hull designs. Information was obtained from classification societies; U.S., European, and Japanese shipyards; coating manufacturers; maritime magazine articles; reports; and the U.S. Navy to determine the current maintenance and repair practices for inter-hull spaces. This information was assimilated and organized into a recommended inter-hull space preservation protocol. The protocol unified individual 'good painting practice' inputs from the various references into a process which is expected to provide 20 years of corrosion protection to the inter-hull space.
