A study on application to marine accident of human reliability analysis method

The purpose of this study was to perform quantitative evaluation of human error in marine accidents by post-hoc analysis using the human reliability analysis (HRA) method. Since most marine accidents are caused by human error, it is important to identify which human errors are most important in marine accidents. In the quantitative evaluation of human error, we used the Technique for Human Error Rate Prediction (THERP) as one of the HRA methods. Based on the results of the event tree analysis of a marine accident, THERP was performed. In conclusion, it was found that it is possible to apply THERP to the analysis of human error in marine accidents.
