heal.abstract	During that last twenty years there have been numerous procedures for the simulation of ship groundings. These are usually based on simplified assumptions that concern the loading of the ship bottom structure and the structural response modes. More recently the increase in the computing power have made possible the simulation of grounding using FE codes, which do not need an a priori assumption for the failure mode of the structural elements. However, other elements of the analysis, such as the description of the sea-bed and the modelling of the material are still under investigation and there have not yet been established guidelines for their inclusion in a grounding analysis. The paper presents an investigation of the loading patterns that are applied to the bottom structure during grounding, reviews and discusses analytical and numerical methods for grounding analysis, and compares the results of six methods when applied to simulate the grounding of aVLCC that occurred in 1975. © 2007 Taylor & Francis Group, London.	en
