520 |aA ship travelling in a seaway can often experience slamming characterized by large sudden loads from impacts with waves. These loads can be large enough to cause local damage, but also induce a whipping response which stresses the primary hull structure and adversely affects the overall fatigue life of the vessel. Most common seakeeping prediction programs use potential flow theory that cannot directly simulate the physics of slamming. This report contains a study using more advanced computational fluid dynamics methods which can reproduce wave impacts. Simulations were conducted for a ferry hull travelling in head seas and compared to existing experimental data. It was found that slamming loads are well predicted, but there can be difficulties in generating and propagating large steep waves inside the simulation.
