SHIP TURNING TRAJECTORY IN REGULAR WAVES

The paper presents the results of a study on the turning trajectory in regular waves. Using a 5.0 m long, self-propelled ro-ro ship model, extensive model experiments of the turning motion in regular waves were carried out and the wave effects on the turning trajectory were investigated from a view point of the wave drifting forces. The deviation of the turning trajectory in regular waves from that in calm water is discussed, and the effects of the rudder angle and the ship speed on the deviation are clarified. A calculation method for the turning trajectory is proposed. Order from NSFI as No. 22141.
