A study of a collision avoidance support system

Recently, shipping industries has become required safety ship operation with fewer crews. On the other hand, recent progress of information and telecommunication technologies is remarkable. The industries would also like to employ these technologies to make the ship operation safer and more efficient. In this study, we propose and discuss collision avoidance support system. The support system proposed in this paper warns the watch officer of the danger and starts planning collision evasion route with the collision avoidance algorithm when the ship faces the risk of collision. Then it shows the most feasible evasion route on main console. For searching the optimal route under collision avoidance support system, this study considers two methods. To evaluate the effectiveness of the methods, some simulations are carried out. In this paper, the details of each method and the simulations that is carried out to evaluate their effectiveness are described.
