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 du e 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 ABA QUS and energy conservation during a grounding scenario on rigid slope take s place. The results are presented both analytically and numerically and co mparison in the energy quantities is shown and discussed. (C) 2000 Publishe d by Elsevier Science Ltd.
