Abstract: Based on the key processes of LNG receiving terminals, this paper focuses on the fire safety analysis during process operation. Firstly, the properties of liquefied natural gas (LNG) and the current situation of the domestic LNG industry are introduced, followed by an emphasis on the important role of LNG receiving terminals in the energy supply chain. Taking an LNG receiving terminal—the first one independently introduced, constructed and managed in China—as a case study, the potential fire hazards in key process flows such as ship unloading, storage and BOG treatment are discussed, with its Class A hazard level and potential risks including pool fires and jet fires identified. Furthermore, starting from facility design, an "intelligent + integrated" fire prevention system is established, and a management closed loop featuring "responsibility + system" is improved. Corresponding preventive measures are proposed to provide references for the safe operation of LNG receiving terminals.

Key words: LNG receiving terminal, fire risk, fire prevention technology
