Furthermore, collision may result in the consequently oceanic catastrophes, etc. In order to protect and to maintain the ocean environment and to promote the crew’s safety, as well as to minimize the losses and damage after accident, special designs for anti-collision and navigational safety has been taken into consideration in the last two decades. In the engine room the propulsion unit, power unit, and key equipment, and kernel of control system of ships are installed. If the engine room section of ship is struck, the serious consequence and escape of fuel oil may be caused with very high probability. In this paper, the engine room section of an 8,236TEU container was selected case study. The conditions of structural damages and impact characteristic of engine room section were examined. The structural damage of both colliding ships, the motion of ships were analyzed. The results of different cases were compared. The effects of change of local structures in engineering room on the crashworthiness were also investigated. At last, investigates the effect on collision, causing from partial filled fluid in side tank of a double hull container ship on the impact resistance for facilities in engine room the consequent crashworthiness hull structures in ship collision will be investigated. The LS-DYNA nonlinear finite element analysis program was used to analyze the ship collision in this paper. Using high deformable bow and also high ductile material for hull structure has the best results to improve crashworthiness of structure in ship collision, nevertheless, the design of ship structures may have changed significantly; using partial filled fluid in side tank can also improve the crashworthiness of ship structures, and it needs only small change of structural design.
