Application of Risk Evaluation Model of Collision Avoidance to a Port Reconstruction Planning

Abstract

When a port reconstruction project is planned, it is necessary to investigate ships' safety and efficiency of operation which is affected by alternation of shore shape or sphere. And nowadays, marine traffic simulation is often used to evaluate a difficulty of ship operation within a planned area. Authors have been proposed the risk evaluation model of collision avoidance which can reflect an influence of geographical condition, sea condition and ship's manoeuvrability into the index value in the previous papers. And in this paper, as the application to a port reconstruction planning, we have evaluated the difficulties of ship's manoeuvring in a harbour area, carrying out the marine traffic simulation. As the result of above simulation, it is found that our evaluation model of collision avoidance can express properly the mental load of mariners, and useful when it is applied to port reconstruction planning.
