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 werecarried out in regular waves in seven wave directions. The motivationfor the investigation is the powering performance of ships in waveconditions. A new towing arrangement allows the ship modelpractically free motions in oblique seas, but makes it simultaneouslypossible to measure the towing resistance. The maximum resistancewas encountered in bow quartering seas. The measurements show thatpractically all ship motion components have a clear effect on the waveadded resistance. The wave elevation measured around the ship showsa clear correlation with the measured wave added resistance values.
