Abstract : The unit impulse response function derived theoretically from the frequency response operator of a moored model platform 5 feet long, 8 inches wide and 6 inches deep is used to predict the model motions in heave due to particular trains of impulsively generated waves with typical wave heights of 3 to 5 in. in water 2.5 ft deep. Experiments carried out in the NCEL Wave Basin are described and a comparison is made between analytically predicted motions and those measured. It is found that the agreement is fairly good and it is concluded that with improved accuracy in the determination of the frequency response operator, the technique may readily be applied in the determination of the response of a floating vessel to impulsively generated water waves.
