STANDARDIZATION TRIALS OF THE STABLE SEMISUBMERGED PLATFORM, SSP KAIMALINO, WITH A MODIFIED BUOYANCY CONFIGURATION

This report contains the results of heavy, medium, and light displacements standardization trials conducted on the Stable Semisubmerged Platform (SSP) KAIMALINO in a new buoyancy module configuration. Measurements of shaft rpm, shaft torque, ship speed, ship's heading, position of ship's control surfaces, ship's roll, ship's pitch, and relative wind velocity and direction were made throughout the speed range of 4.68 to 17.96 knots. A comparison of power characteristics of the old and the newly increased buoyancy configurations is presented. The new buoyancy scheme proved significantly superior below 13.2 knots and less desirable above that speed. Comparisons are made between the ship's automatic control system and a fixed control surfaces condition. No significant powering changes were noted. Comparisons between different nominal trim conditions were made which produced modest differences. Calm and nominally rough water trials were also compared and the effects of the sea state on powering characteristics was found to be minimal. (Author)
