Comparison of numerical approaches for structural response analysis of passenger ships in collisions and groundings

Sang Jin Kim et al.

Summary: The dynamic response of ships following grounding and collision accidents may be influenced by structural topology, operational and environmental conditions. Computational methods offer a useful alternative in accurately capturing crushing mechanisms with consideration of hydrodynamic influences. Simulations for typical accident scenarios confirm the importance of hydrodynamic restoring forces and the sensitivity of damaged area to the failure strain values in grounding scenarios.

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

Sang Jin Kim et al.

Summary: This paper presents a procedure for simulating the influence of strongly coupled FSI effects on the dynamic response of ships in collision and grounding events, highlighting the importance of suitable FSI modeling in accident scenarios primarily due to the influence of hydrodynamic restoring forces. The method couples an explicit 6-DoF structural dynamic finite element scheme with a hydrodynamic method, accounting for various influencing factors.
