Energy conservation during grounding with rigid slopes

In this paper a numerical approach to the grounding problem takes place. It aims to show the contribution of the energy dissipated in the structure due to elasto-plastic deformation. The analytical methods developed until now, neglect this amount of energy, since they are simulating the vessel as a rigid beam. A tanker vessel is modelled with the Finite Element Package ABAQUS and energy conservation during a grounding scenario on rigid slope takes place. The results are presented both analytically and numerically and comparison in the energy quantities is shown and discussed.
