Fishing vessels, having relatively small freeboard, are prone to encounter a water-shipping event in severe sea states. The water impact and accumulated water effects could make fishing vessels be unstable and capsize in the worst-case scenario. Therefore securing the safety of fishing vessels under water shipping situations is an important subject, but it is not easy to predict the water behaviour in water shipping situations, where over-topping, water impact, largely deformed free-surface and strong coupling with ship motions appear compositely. hi this paper, SPH simulations using GPU are applied to the prediction of 6DoF ship motions in severe water-shipping condition. Then the prediction accuracy of the SPH method is systematically investigated through comparisons with dedicated captive and free motion tests. (C) 2016 Elsevier Ltd. All rights reserved.
