A 3D domain-decomposition strategy for violent wave-vessel interactions

The water-on-deck is a transient nonlinear phenomenon induced by wave-vessel interactions, especially when severe incident waves and large vehicle motions happen. Green water is characterized by compact masses of liquid exceeding locally the freeboard, they enter the vessel and may flow/slosh/impact on the deck. The vessel type, its operational conditions and the incident-wave features are the major parameters of the problem, affecting the occurrence, severity and behavior of the shipped water. Green-water loads may be characterized by high localized peaks, as well as by a more persisting and global behavior. They represent a danger for safety, operations and comfort.
