Numerical simulation of Green Water on FPSO

FPSO can suffer great danger from Green Water,and severe Green Water can cause structure damages.This paper presents a three-dimensional numerical wave tank,which has been developed.A fixed FPSO is placed in the regular wave to simulate the phenomena of Green Water.Impact loads,wave height on the deck,the course of wave running up the stem,wave deforming and wave breaking can be obtained.Dynamic boundary was used to make waves and free surface to be captured by VOF method.In the posterior segment of the tank,sources term is added into the momentum equation to eliminate the reflection of the end wall.
