Ship accidents involving collision or grounding often have significant environmetal effects. Classification societies are therefore active in developing new guidelines for the risk and safety assessment of ships with respect to the structural design of ship bottoms in the view of potential grounding. A multi-level mathematical model for the simulation of the ship grounding assumes the soil as flexible contact partner. The equations of motion are based on Timoshenko beam model of theory 2(exp)nd oder completed by relevant hydro-dynamical terms. The time-domain solution includes simultaneously a coupling with a spatial finite-element boundary-element model for realistic handling of the soil-structure interaction considering hydrodynamic effect, geometrical non-linearity and plasticity of structure, and frictional influences of the seabed as flexible half space. Simulation of the grounding process provides the information to time-dependent progression of the essential quantities of kinematics as well as internal forces, stresses, structural damages caused by soil contact and energy dissipation.
