DESIGN AND DEVELOPMENT OF THE 190-TON STABLE SEMISUBMERGED PLATFORM (SSP)

The general characteristics, design features, predicted performance, and construction highlights of the 190-ton Stable Semisubmerged Platform (SSP) are presented. The SSP is the first large manned version waterplane area. The SSP was designed to provide an order-of-magnitude improvement in motion reduction over monohulls, as well as provide more deck space and internal volume. The SSP is 89-feet long and has an expected top operating speed of 25 knots with about 44 tons of payload and fuel. Design of the SSP features two parallel torpedo-like hulls which support an above-water cross structure by means of four vertical surface-piercing struts; two canard fins are located near the hull bows and a cross stabilizing fin is located near the hull sterns. The SSP was constructed at the Coast Guard Shipyard at Curtis Bay, Md.
