Assessment of Human Error Probability in Emergency Evacuation Using HEPI Method in Offshore Industry

摘要

Introduction: Offshore emergency operations are one of the most potentially hazardous incidents. Considering the major role of human factors in this operation, human error assessment is necessary in this section. In this research, the human error levels in emergency evacuation have been evaluated by using the HEPI method.Materials and Methods: This research was conducted on 17 and 18 alpha platforms in South Pars region. In this regard, the ranked aggregation questionnaire for the HEPI index has been completed based on event factors, stress, complexity, climate conditions, training and experience for collecting data.Results: The results showed that the risk of the process of returning to safe mode, the activity of immunizing the environment, moving the way to the emergency exits, identification of emergency exits and registering in the TSR was unacceptable. By carrying out corrective actions such as training, repairs, use of safety signs, preparation and delivery of emergency response plans and training for personnel, these activities were within acceptable limits.Conclusion: According to the results of this study, conducting more maneuvers with respect to their feedback can be effective in reducing the risk of reaction in emergency evacuation. A tool such as HEPI can also provide a better understanding of the concept of human error.
