Research on optimization of evacuation paths for personnel in offshore platform fire
In order to analyze the safety evacuation situation of operators in the fire on offshore platforms,and put forward the suggestions for path optimization of emergency evacuation,the PyroSim software was used to restore the smoke spread law after the ignition of fire source on offshore platform.The change in smoke temperature,visibility,and CO volume fraction over time was studied,and the fastest time for each parameter to reach the limit value was selected as the available safe evacuation time for operators.The fire situations in different scenarios were coupled with the evacuation of operators by using Pathfinder,and the required safe escape time for operators to escape from dangerous locations was obtained through the comprehensive analy-sis on evacuation situation.The results show that the risk coefficients of drilling area space and corridor 2 are relatively high.The research results propose the optimization suggestions for the evacuation paths of operators at different initial locations.
