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 of a high-speed displacement craft concept having a small water-plane area. The SSP was designed to be a work platform for research and testing of advanced Naval equipment at the Naval Undersea Center. Its unique design will 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 a top operating speed of about 25 knots with about 25 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. (Modified author abstract).

The form, hydrodynamic design, and predicted performance of the 190-ton Stable Semisubmerged Platform (SSP) are described and analyzed. Design criteria are presented for the twin submerged hulls, four surface-piercing struts, bow section of the above-water cross structure, aft stabilizing fin and flaps, forward-mounted canard control surfaces, rudders, and the controllable and reversible propellers. Hydrodynamic loads and motion in waves are analyzed. The overall design is evaluated in light of design experience, model test results, and preliminary operating experience with the 190-ton SSP. The 190-ton SSP is shown to have significantly reduced motion in waves, increased rough-water speed and more deck space and internal volume than conventional monohulls. (Author).
