Numerical Simulation of Collision Between an Oil Tanker and Ice
The ice floe has a great influence on the speed and navigation safety of polar ships. Whether it is the exploitation of oil and gas or the opening of new lanes, the problems of ship-ice collisions should be paid close attention to. In order to further study the collision response of the side structure under ice loads, the finite element technology is used to simulate the collision process between the ship and ice in this paper. The crashworthiness is compared and analyzed according to the results of stress, strain of side structure and energy absorption during ship-ice collisions by selecting different ice impact speeds. The numerical results provide certain technical supports for the structural damage prediction and evaluation of ships sailing in the ice areas.
