摘要：This paper classifies more than 20 accidents according to the main factors and types of accidents from 1994 to now. Through analysis, it is found that the safety attachment of LNG pressure control is a weak link in LNG storage system. The safety attachment of LNG pressure control is analyzed from four aspects of people machine Environmental management, and the fault tree model is established. After calculation, the minimum cut set and structural importance of the safety attachment of LNG pressure control are obtained. Based on the fault tree analysis results of LNG pressure control safety accessories and the statistical results of 20 accidents, control measures and suggestions are put forward from the peripheral layout, electrical, equipment, installation, production operation, daily maintenance of LNG pressure control safety accessories, in order to prevent and reduce accidents caused by LNG pressure control safety accessories.
