HYDRODYNAMICS OF THE 190-TON STABLE SEMISUBMERGED PLATFORM (SSP)

The form, hydrodynamic design, and predicted performance of the SSP are described and analyzed. Particular design areas covered are 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 over-all design is evaluated in light of design experience, model test results, and preliminary operating experience with the SSP. Results are presented which indicate significant reduction in motion in waves, compared to monohulls, as well as a significant increase in rough-water speed.
