Human error probability in the emergency evacuation

Abstract

This study aims to determine the human error probability during the emergency evacuation of offshore platforms with the HEART technique. In this study, after completing an emergency maneuver with a fire and explosion scenario, the HTA method was used to identify and segregate the emergency evacuation activities, and the HEART technique was utilized to estimate the human error probability. Lastly, suitable control measures were suggested based on the evaluation's findings. In the event of a fire and explosion, the safest means of evacuating people and leaving the platform include evacuation by lifeboat, evacuation by rescue floats and rescue ships nearby, and evacuation by helicopter. Due to the extreme risk, evacuating individuals via life rafts and jumping directly into the water is not recommended. It is advised to examine the safety state of the platform, organize specialized safety training and weekly maneuvers for personnel participating in the emergency evacuation procedures of the platform, and monitor the repair, maintenance, and inspection status of the employed equipment.
