Abstract: With the rapid development of marine oil and gas exploitation, the evacuation of offshore platforms has received more attention. First, an experimental investigation of the evacuation process of 120 participants in a real offshore platform is performed, and then simulation results provided by Pathfinder are validated against the measurement results. Second, four typical evacuation scenarios on the platform referring to IMO guidelines are investigated by Pathfinder with the speed values achieved in experiments. The simulation results show that both the utilization of exits and evacuation efficiency of people on the offshore platform need to be further improved. Last, the evacuation routes of people under the four scenarios are optimized, and the improvement of the evacuation performance after the optimization is evaluated by several mathematical indicators. Final results show that the evacuation with the optimized route design prompts the use efficiency of exits and further reduces the evacuation time. The present study provides a useful advice for potentially revising the IMO guidelines in future and provides efficient evacuation strategies for planning the emergency evacuation on offshore platforms.

摘要： 随着海上油气开发的快速发展，关于海洋平台的人员疏散问题越来越受到人们的关注。本文首先在实地海洋平台上针对120名人员开展疏散实验，并运用Pathfinder对该疏散实验场景进行模拟，软件疏散模拟数据与实验结果匹配度高。其次，参考IMO疏散导则和使用实验速度数据，针对平台上四种典型疏散场景进行仿真模拟研究。仿真结果表明，海洋平台疏散场景的出口利用率和人员疏散效率有待提高。最后，针对四种疏散场景下的人员疏散路径进行优化，并用多个数学指标来评价优化后的不同场景的人员疏散性能。最终结果表明，人员按照优化路径进行疏散有助于提高出口使用率，缩短疏散时间。本研究对IMO疏散导则的修订工作有一定参考价值，并为海洋平台紧急疏散提供了有效疏散策略。
