The preparation, conduct, and analysis of full-scale powering trials on the Stable Semisubmerged Platform (SSP), SSP KAIMALINO, are presented. The overall trials program, sponsored by the Small Waterplane Area Twin Hull (SWATH) Ship Project Office is discussed in general. Two specific areas, turning trials, and speed and powering trials, are presented in detail. Turning data revealed that the SSP has a tactical diameter on the order of ten to twelve ship lengths. Speed and powering data showed that the SSP was able to achieve a speed of 19.08 knots at an average shaft horsepower of 2936 (2189kw), an average shaft RPM of 307.8, and an average propeller pitch of 90 inches (229 cm), while operating at 75 percent of design propeller shaft torque. Powering data obtained during rough water trials revealed an increase in powering of 5 to 6 percent over the power required in smooth water in order to maintain a speed of 17 knots in a high State 3 sea. The speed and powering data are compared to data obtained on an 11-foot (3.35) model, and are found to be in excellent agreement. (Author)
