    Abstract

    A model for prediction of damage to tankers during grounding is presented. The model takes into account the coupling between the external ship dynamics and the local damage process of the hull girder. The model for the local damage is based on a least upper bound solution with kinematic compatibility between all structural members. Friction is taken into account and it is shown how friction contributes to the horizontal resistance force and the vertical reaction force. The resistance of the structural members is expressed in closed forms thus requiring very small modeling time. The model was validated by small scale tests and a large scale test. Application of the theory is illustrated by a study of the grounding damage of a single hull VLCC.
