SEAKEEPING NUMERICAL ANALYSIS IN IRREGULAR WAVES OF A CONTAINERSHIP
Keywords:
numerical seakeeping analysis, dynamic response, seakeeping criteriaAbstract
In the present work, a seakeeping analysis of a containership of 139,96m length, is performed. The study includes the linear seakeeping analysis, coupled heave and pitch motions, uncoupled roll motion, in irregular waves, heading angle 0 - 360 deg., with Pierson-Moskowitz wave power density spectrum. The numerical seakeeping analyses are carried on with an original DYN_OSC program code based on linear seakeeping method and statistical short term prediction response method. Taking into account the specific limits of seakeeping criteria, the dynamic response statistical polar diagrams are obtained for each motion degree and the cumulative one, pointing out the influence of the ship speed and heading angle for seakeeping assessment
