“…This method is capable of coupling external and internal mechanics. Several research articles have presented results of FSI-based simulations that use LS-DYNA's ALE formulation (see Table 1), e.g., simulations of ship-rigid structure collision [22], ship-ship collision [6] and ship-iceberg collision [23], but validation is lacking. Hydrodynamic loads and ship-ice interaction loads were numerically calculated based on the FSI method by Wang and Derradji-Aouat [24], in which the wave maker simulation showed the good FSI results with regard to wave length comparison.…”

The structural damage of ships in navigational accidents is influenced by the hydrodynamic properties of surrounding water. Fluid structure interactions (FSI) in way of grounding contact can be idealized by combining commercial FEA tools and specialized hydrodynamic solvers. Despite the efficacy of these simulations, the source codes idealizing FSI are not openly available, computationally expensive and subject to limitations in terms of physical assumptions. This paper presents a unified FSI model for the assessment of ship crashworthiness following ship hard grounding. The method uses spring elements for the idealization of hydrostatic restoring forces in 3 DoF (heave, pitch, roll) and distributes the added masses in 6 DoF on the nodal points in way of contact. Comparison of results against the method of Kim et al. (2021) for the case of a barge and a Ro–Ro passenger ship demonstrate excellent idealization of ship dynamics. It is concluded that the method could be useful for rapid assessment of ship grounding scenarios and associated regulatory developments.
