Gravity platforms, together with associated regions of foundation and fluid, are idealized using the finite element method. Radiation of wave energy away from the platform region is modelled by appropriate damping applied to the boundary of the foundation mesh. Response results, due to sinusoidally applied forces, are calculated for seven platform-foundation configurations. Of particular interest are those results for various assumed foundation conditions, including the presence of stiff soil layers. The response of these platforms due to North Sea storm conditions is also estimated. It is concluded that a simple static analysis of the platform-foundation system does not necessarily give an accurate prediction of the response under extreme loading conditions.
