ABSTRACT
Effective ship design measures may significantly reduce risks associated with loss of life, asset safety, or environmental contamination. This is especially prevalent for those cases that the degree of accidental damage is adequately identified and implemented in engineering practice, rules and regulatory developments. This paper presents a summary from recent research on structural crashworthiness accounting for the effects of ship dynamics on grounding. Comparisons of commercial FEA LS-DYNA-MCOL simulations against (i) a two-way coupled Fluid-Structure Interaction (FSI) model by Taimuri et al., (2022) and (ii) a super-element (SE) method by Le Sourne et al., (2012) are assessed and compared with the aim to demonstrate the validity of rapid models in scenarios where passenger ships may experience off-center hard grounding. It is concluded that further research in this area could significantly contribute to the development of future classification rules and the IMO SOLAS regulatory instrument.
