Development of a method for marine accident analysis with concepts of PRA

There are a lot of marine accidents caused by human factors. The experiment using bridge simulator is effective for analysis of the human factor. However, the analytical approach for the navigational behavior by the experiment with bridge simulator has not been established yet. The purpose of this paper is to propose an analytical approach by introducing concepts of Probabilistic Risk Assessment (PRA) and the experiment using bridge simulator that can find out the important factor to avoid marine accidents. As a result of experiments and the analysis, it is clearly important that the officers judged the necessary of the constant lookout for dangerous targets. Finding the important factor of avoiding marine accident, this analytical approach is effective.
