摘　　要：LNG储罐是液化天然气储运过程中的重要设备,其安全问题尤为重要。以bow-tie方法为基础,对LNG储罐泄漏这一灾害进行详细分析。通过分析,得到LNG储罐泄漏的详细原因以及可能发生的事故后果并且在概率未知的前提下利用灰色关联度方法找出导致事故发生的关键原因,从而有针对性的采取预防措施,在本质上防止泄漏事故的发生进而避免其造成更严重的后果。LNG tanks are important equipments in the process of liquefied natural gas storage and transportation, its security problem is particularly important. In this paper, based on the method of Bow-tie, detailed analysis on the leakage of LNG tanks was carried out. The detailed causes and possible accident consequences of the leakage were obtained by analysis. In order to take effective measures of preventing leakage specifically and avoiding more serious consequences, the crucial cause of the accident was determined by the grey correlation analysis method on the premise of unknown probability.
