Numerical Simulation of Green Water and the Safety Analysis Research on Structures and Equipments

With the high speed development of ship building and the widely use of the deep-sea oil platforms in severe sea conditions, green water have attracted more and more attention. Based on the relative motion of ship and wave, a numerical simulation of the distribution of green water on the wet deck of ship is achieved according to the dam break model and flood wave model, and the strength of local structure is calculated. In addition, the calculation model of the impact force on the objects of wet deck is got through the momentum theorem in hydrodynamics, which is used to analyze the safety of the equipment on the wet deck. The research is significant to the safety of the ship and the platform in rough sea.
