Human error risk analysis and reduction for offshore emergency situations

The presented methodology provides a quantitative approach for the assessment and reduction of the risk of human error probabilities during emergency situations. Previous research on the escape phase of the escape, evacuation and rescue (EER) process has resulted in the identification of tasks, the risk of human error and potential risk reduction measures for the escape phase. Tasks that must be completed in the evacuation and rescue phases were identified in the current thesis. Due to a lack of available human error data, a combination of expert judgment techniques and a literature review of previous incidents were used to evaluate the risk of human error for the evacuation phase. ARAMIS was used to evaluate the effectiveness of risk reduction measures. Novel concepts include introducing the hierarchy of controls into the procedural HAZOP and the combination of a human error risk assessment methodology (HEART) with a comprehensive risk reduction methodology (ARAMIS).
