Experimental Investigation on Ship Wave Added Resistance in Regular Head, Oblique, Beam, and Following Waves

摘要

Measurements on wave added resistance of a cruise ship model were carried out in regular waves in seven wave directions. The motivation for the investigation is the powering performance of ships in wave conditions. A new towing arrangement allows the ship model practically free motions in oblique seas, but makes it simultaneously possible to measure the towing resistance. The maximum resistance was encountered in bow quartering seas. The measurements show that practically all ship motion components have a clear effect on the wave added resistance. The wave elevation measured around the ship shows a clear correlation with the measured wave added resistance values.
