Developing a framework for assessing risks associated with human responses in emergency escape on offshore installations

Abstract

This paper presents a framework for assessing and managing risks of personnel responding to emergencies requiring escape on offshore installations. Personnel’s action or response can be affected by human factors during the emergency escape. The framework has four categories: analyzing human factors in safety barriers for emergency escape, quantifying the failure probability of personnel’s response, assessing risks associated with personnel’s response, and managing the risk associated with personnel’s response. The first category requires defining and arranging safety barriers for emergency escape based on the Swiss cheese model. Both second and third categories calculate the probability of personnel failing to respond to emergency escape using Bayesian analysis. A safety hierarchy for managing risks associated with personnel’s response is introduced in the fourth category.
