Abstract: The bow of a ship colliding directly to another ship’s amidships is the worst situation in ship-ship collision. In order to improve the crashworthiness of the ship,the sandwich material,such as honeycomb sandwich plate,tube-style sandwich panels,folding sandwich plate etc. can be filled in the side of the single-hull bulk carrier to increase the energy absorption capacity of side structure. The damage deformation,the critical collision speed as well as the energy absorption of improved side structure filled with sandwich are compared with the conventional type of side structure under lateral dynamic loads by MSC / Dytran. The results indicate that the improved side structure filled with sandwich can remarkably improve the side structure’s ability against collision,and the effect of the tube-style sandwich panels structure is best whose upper skin is the main energy-absorbing component.
