ROLLING OF SHIPS UNDER SHIPPING WATER CONDITION

This paper deals with the problems associated with the effect of water shifting on a ship rolling in beam sea. The motion of deck water is modelled by shallow water equation and solved by Glimm's random choice method. The hydrodynamic forces acting on the ship are determined by boundary element approach in time domain. The motion of the ship and the deck water are calculated and illustrated. Although only two dimensional cases are considered for the sake of simplicity, the calculation can easily be extended to a full scale ship by using the strip method.
