Dynamic risk assessment of escape and evacuation on offshore installations in a harsh environment

Abstract

The execution of escape and evacuation on offshore installations in harsh environmental conditions poses potential risks. A quantitative risk assessment focusing on escape and evacuation must be introduced to improve the safety of personnel performing these activities. This paper presents a risk assessment for escape and evacuation systems on offshore installations conducted in harsh environmental conditions. The research work uses Bayesian analysis and binomial distribution to demonstrate the impact of harsh environmental conditions to personnel performing escape and evacuation on offshore installations. The probability of success of personnel detecting alarms can be affected by environment conditions. Risk assessment considering environmental conditions illustrates the importance of defining the risk acceptance criteria to be used for safe escape and evacuation.
