ABSTRACT
This chapter examines the parameters that affect the collision process and the residual ultimate longitudinal strength of ship structures. It analyses the Finite Element method was applied first to simulate the collision process between Suezmax tanker and iceberg with semi-sphere geometry, in which the effects of collision position, velocity and angle on the damage range of hull girder. Ships are vulnerable to ice collision in arctic region, requiring more attention on the research of ship-iceberg collision and the residual ultimate strength of the damaged ship structure. M. Kwak et al. compared the result of ship-ice collision simulation with the value defined in International Association of Classification Societies Polar Rule in order to iteratively modify the properties of the ice material model and improve its effectiveness. A ship-ice contact model was developed to simulate the structural response and the global motions of the ship and ice efficiently.
