The influence of fluid structure interaction modelling on the dynamic response of ships subject to collision and grounding

Analysis of the dynamic response ships in accident scenarios requires a realistic idealisation environmental and operational conditions by multi-physics models. This paper presents procedure that simulates influence strongly coupled FSI effects on involved typical collision grounding events. Our method couples an explicit 6-DoF structural finite element scheme with hydrodynamic accounting for (a) potential flow actions; (b) evasive ship speed way contact (c) resistance based RANS CFD model. Multi-physics simulations involving passenger confirm suitable modelling may be critical either or events primarily because restoring forces.
