Onshore LNG receiving terminal is an important facility in offshore LNG import system. According to the growing human accidents of LNG receiving terminals in China at present, based on the HFACS analysis of accident causation model which had been used in the aviation accident investigation, the impact factors of human accidents were divided into five categories, which contain personal factors, group factors, environmental factors, supervision and organizational factors, and the human accidents identification method of LNG receiving terminal was obtained based on grey relational analysis of gray theory. Finally, the method was applied to identify the accidents happened in an LNG receiving terminal, and it was found that the main insecurity events were "the una-wareness of security" in "personal factors" by calculating the grey relational grade. This method overcomes the disadvantage due to the small sample of accident data, which has certain guiding sense to safeguard the safety operation of LNG receiving terminals.%陆岸LNG接收终端是LNG海上进口系统中的重要设施.针对我国LNG接收终端人因事故不断增多的现状,基于航空事故调查分析中的HFACS事故致因分析模型,将人因事故的影响因素归纳为个人因素、人际因素、环境因素、监督因素和组织因素五大类,结合灰色理论中的灰色关联分析,得到了LNG接收终端人因事故辨识方法.最后,运用该方法对某LNG接收终端人因事故进行辨识,通过灰关联度的计算,找出其最主要的不安全事件来自“个人因素”中的个人“安全意识不强”.此方法克服了小样本事故数据带来的弊端,对保障LNG接收终端的安全运行具有一定的指导意义.
