PHM/JETFOIL RELIABILITY AND SERVICE EXPERIENCE

Jetfoil and PHM are two hydrofoil vessels designed and built in generally the same time frame. One was designed as a commercial passenger-carrying vessel; the other, of twice the displacement, a missile-carrying patrol craft. Both models have acquired a substantial amount of operational experience. This paper reviews similarities and differences in the evolution of these two vessels from a reliability/maintainability viewpoint. Jetfoil was designed to American Bureau of Shipping (ABS), U.S. Coast Guard, and Hong Kong authority requirements. PHM is a joint Boeing/U.S. Navy design based upon a Memorandum of Understanding among three NATO nations. Examples of similarity and differences in design and operation experience are described in this paper. For example, failure mode analyses and tests for the fully submerged hydrofoil automatic control system were similar for both models. The same fix was successful in correcting initial operational problems with that system's height sensor in both models. Each of the designs used a different approach for the vessel's seawater system and different problems were encountered.
