《GB/T 20368-2012液化天然气（LNG）生产、储存和装运》由TC355（全国石油天然气标准化技术委员会）归口，TC355SC1（全国石油天然气标准化技术委员会液化天然气分会）执行，主管部门为国家标准化管理委员会。

Scope

This standard specifies the fire protection, safety and related requirements for site selection, design, construction, security, operation and maintenance of LNG plants. This standard applies to natural gas liquefaction facilities, liquefied natural gas (LNG) storage, gasification, transshipment and handling facilities, personnel training in LNG, and the design, siting, construction, maintenance and operation of all LNG facilities. This standard does not apply to underground storage tanks in permafrost, mobile storage tanks stored or used in buildings, and all LNG vehicles including LNG vehicle filling.
