NEW EXPERIMENTAL TECHNIQUES ON SHIP MOTIONS IN DIRECTIONAL SPECTRUM WAVES

Real sea surface is expressed by short crested irregular waves with continuous directional spectrum. These waves will be called directional spectrum waves. For conducting running ship experiments in short crested irregular waves, a new type of directional spectrum wave generator was developed for a towing tank. Also, a new, non touch type, wave surface probe was developed for obtaining the encounter directional wave spectrum especially in the high speed running condition. Finally, a new estimation of directional transfer function of ships or floating bodies was developed from experiments in directional spectrum waves.
