TOWED SHIP MOTION TEST IN DIRECTIONAL SPECTRUM WAVES IN A LONG TANK

The techniques of generating short-crested waves with an arbitrary directional spectrum have been developed. Although some experiments have been conducted in such waves, ship towing or running tests have been precluded by the lack of a sufficiently uniform experimental area. This paper reports on ship motion tests in the towed condition, with Froude numbers 0.2 and 0.275, carried out in a long tank by generating uniform irregular waves with an arbitrary directional spectrum. Analyzed results are compared with theoretically-estimated results, and there is relatively good agreement. For the experiment, a snake-type wave maker was newly developed and installed at the end of a long tank at Yokohama National University.
