Abstract: Three dimensional Rankine source model is developed to investigate the hydrodynamic responses for oscillatory body within uneven seabed conditions. The free surface, seabed surface and body surface are presented by layer of continuous panels. The accuracy of the numerical solutions are validated by comparison with published data for flat seabed conditions. The influences of ellipsoid shape seabed and sloping seabed are investigated. Numerical simulations demonstrate that various seabed profiles have significant and complicated effects on the body hydrodynamic response characteristics.
