Maneuvering Simulation of Two Ships During Meeting and Passing

Motion equations of two ships maneuvering in close proximity are solved in consideration of the interaction between hulls. the interaction forces are calculated by a 3d panel method as a function of the ship position in the time step and considered as external forces in maneuvering. four kinds of ships are prepared and the maneuvering motions are simulated with variation of the combination of ships, water depth, ship speed and draft. the effect of those parameters on the interaction forces and two ships behaviors are investigated.
