船員災害防止に向けた災害発生要因の分析に関する研究

抄録

The purpose of this study is to establish a method that can reasonably identify the occurrence factors of the disasters and examined whether the method in this study would be an effective resource for planning safety measures for prevention of seafarer’s disasters.

The occurrence factors of seafarer’s disasters are identified by the Common Performance Conditions (CPCs) which used in the process of identifying the causes in Cognitive Reliability and Error Analysis Method (CREAM). As a result of analyzing 100 cases, we identify all the matters pointed out by the Japan Transport Safety Board (JTSB) as the causes and show the validity of this method. From the specific results, “Working in a dangerous area” is the most important factor in an accident.

The relationship between the occurrence factors is examined, and it is found that there are strong links between the 3 factors such as "organization", "environment" and "human-machine interface", and "work in dangerous areas" is central to the relationship between many factors. Based on these relationships, comprehensive measures against multiple factors can be considered, so it seems that safety measures can be examined more efficiently.
