Naval ships as well as floating offshore units can suffer serious damage due to green water loading. In recent model test research at MARIN the physical behaviour of the shipping of green water has been studied. The non-linear relative wave motion, the complex flow onto the deck and the impact on deck structures were investigated. In the present pilot study an investigation is made into the numerical time domain simulation of the shipping of green water. A fully non-linear boundary integral method is used. As a fïrst step a two dimensional flow onto a deck is studied, without ship motions. The present numerical model is capable of simulating the shipping of green water on a two dimensional conflguration. Some results from calculations are presented. Results from two dimensional model tests justify the simplifïcations made in the present model. However, a number of numerical problems arise, which are also treated in this paper.
