ON THE EQUATIONS OF MOTION OF SHIPS EQUIPPED WITH AN ANTI-ROLLING TANK IN BEAM SEAS

There have been made many studies about an antirolling tank. In most of those studies only the coupling effect between rolling motion and tank fluid motion has been considered using Froude-Kriloff's assumption. This may be the reason among others, no established satisfactory theory about ship motions except rolling motion has been developed. In general, a ship laid broadside on regular progressive waves performs not only rolling but also heaving, pitching, surging, swaying, yawing and drifting motion. In recent years, it has become possible to treat these motions applying the wave making theory for radiation forces and wave exciting forces. In this report, the ship-tank equations of motion are developed based on Tasai's theory about ship motions in beam seas and the comparisons are made with other theories.
