The present invention relates to an liquefied natural gas carrier (LNGC) unloading system. The present invention prevents an explosion due to a cold NG or an LNG remained inside a vapor line after unloading is completed in the LNGC unloading system. According to the present invention, the safety apparatus of an LNGC unloading system is operated to discharge the natural gas to an LNG cargo tank of the LNGC to prevent the vapor line from being exploded due to vaporization and expansion of the cold NG or the LNG remained inside the vapor line after unloading of the LNG is completed.

    본 발명은 LNGC 언로딩(unloading) 시스템에 관한 것으로, LNGC 언로딩 시스템에서 언로딩 완료 후에 베이퍼 라인 내에 잔존하는 차가운 천연 가스(Cold NG) 또는 LNG에 의한 폭발을 방지하기 위한 안전 장치에 관한 것이다. 본 발명의 LNGC(Liquefied Natural Gas Carrier) 언로딩(unloading) 시스템의 안전 장치는 LNG의 언로딩 완료 후 베이퍼 라인(vapor line)내에 잔류되어 있는 차가운 천연 가스(Cold NG) 또는 LNG의 기화 및 팽창으로 인하여 베이퍼 라인이 폭발하는 것을 방지하기 위하여 천연가스를 LNGC의 LNG 카고 탱크(cargo tank)로 배출할 수 있도록 동작한다.
