Many accidents generally end up happenings caused by some factors in connection with other factors, and ship-bridge collision accidents are no exception. To prevent the likelihood of recurrence of ship-bridge collision accidents, it is necessary to investigate what factors contributed accidents and how one factor connected with others. In this study we tried to clear up the processes of ship-bridge collision accidents and to extract important factors related to them by means of Fault Tree Analysis. Fault Tree Analysis is known as a primary method for large-scale-system to evaluate the safety at design stage, but also it would be used for accident analysis; if every factors related to accidents were expressed by figures and accident processes were cleared up, it could be possible to make an effective choice to prevent the accident. By constructing Fault Tree, we could clear up the processes of ship-bridge collision accidents, and could extract some important factors by determining the minimal cut set and the minimal path set for the simplified Fault Tree.
