The success of maneuvering at sea does not only heavily depend on an environment but also human navigators, especially in extraordinary situations. That is, unsafe maneuvering occurs in the situations where navigators have not fulfilled their tasks sufficiently. In this paper, we studied human behaviour leading up to specific situations, where rudder trouble makes human navigators lose their maneuvering ability in the fairway; this fairway has some traffic consisting of other ships. The situation disturbs the ability of the navigators to navigate successfully and causes a potential for unsafe situations to develop. We analyzed some factors consisting of human navigators' behaviour and various situations by using the data of 26 Bridge Team Management raining teams. Then we obtained some correlations between some factors and human behaviour on maneuvering before and after the trouble, and clarified structure of the changing maneuvering process using Fault Tree Analysis. As a result, we obtained the primary factors of human behaviour in extraordinary situations and countermeasures based on it.
