Model Experiments of High Speed Container Ships in Regular Head Waves

Abstract

Self-propulsion tests in regular head waves are carried out of high speed container models with a single screw propeller at the service and the ballast conditions. Ship motions and accelerations, as well as increases of thrust, torque and revolutions of propeller, are measured. The results of ship motions show a fairly good agreement with those calculated by the "Strip method", except in rather a high speed range. An influence of bow flare and height of knuckle line on shipping water is also discussed.
