Time Domain Simulations of 2-D Floating Bodies in Regular and Irregular Waves : Effect of Above-Water Hull Form

Abstract

The accurate prediction of wave-induced motions of floating structures and hydrodynamic forces acting on their hull are one of the main concerns in ocean engineering. Three types of model with different forms above water are used in this study. The simulated results of motions show that the above water hull forms effect on roll response even in small amplitude incident waves whose frequency is near resonance one. To simulate floating body motion in real ocean, a generation method of irregular waves is confirmed. By using it, we simulated motion of floating bodies in irregular waves for long time.
