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
