Model experiments to predict the ship motions and accelerations induced on the Japanese First Nuclear Ship in waves were carried out.The responses of the model ship in regular and irregular waves generated in the model basin were measured. The test results in regular waves are shown as the amplitude ratio to wave height or wave slope against the ship length-wave length ratio for the various wave directions and ship speed. The responses in irregular waves whose energy spectrum was given as a certain standard type, are shown as the standard deviations of the responses to the significant wave height against the velocity for the various wave directions and the mean wave period. The test results were compared with the computed values by the so-called strip theory.Finally, the short term distribution of the responses in irregular extreme sea condition was estimated and compared with the values derived from the foregoing researches. Thrust increase in regular and irregular waves was also measured and the speed loss in rough seas was considered.
