A liquefied natural gas-floating production storage offloading (LNG-FPSO), according to the present invention, comprises: a gas inlet system which allows natural gas to flow from a gas field into the LNG-FPSO; a pretreatment system which pretreats the natural gas flowing by the gas inlet system; a liquefying system which liquefies the natural gas pretreated by the pretreatment system; an LNG storage tank which stores the LNG liquefied by the liquefying system; and a boil-off gas treatment system which recovers and stores the boil-off gas (BOG) generated from the LNG storage tank, thereby efficiently recovering and treating the BOG generated from the LNG storage tank.
본 발명의 부유식 액화천연가스 생산저장하역시설은, 가스전으로부터 천연가스를 인입하는 가스인입시스템, 상기 가스인입시스템에 의해 인입된 천연가스를 전처리하는 전처리시스템, 상기 전처리시스템에 의해 전처리된 천연가스를 액화하는 액화시스템, 상기 액화시스템에 의해 액화된 액화천연가스를 저장하는 LNG 저장탱크 및 상기 LNG 저장탱크로부터 발생되는 증발가스(Boil-off gas, BOG)를 회수하여 저장하는 증발가스 처리시스템을 포함함으로써, 본 발명에 의하면, LNG 저장탱크에서 발생되는 BOG를 보다 효율적으로 회수 처리 가능한 부유식 액화천연가스 생산저장하역시설을 운용할 수 있다.
