Modeling of surf-riding in irregular waves

Abstract

Surf-riding is an important phenomenon for the evaluation of ship dynamic stability, as it is related to one of the principal mechanisms of broaching-to. The evaluation of the probability of surf-riding in irregular waves is a necessary step toward determining the probability of broaching-to following surf-riding. To facilitate the probabilistic study of surf-riding, a simple model of surging and surf-riding in irregular waves of variable bandwidth is introduced. This model can be used to identify patterns of surf-riding in irregular waves.
