Disclosed is an evaporation rate reducing system for a liquefied natural gas cargo hold. According to the present invention, the evaporation rate reducing system for a liquefied natural gas cargo hold includes: a cargo hold in which liquefied natural gas is stored; and a liquid nitrogen storage tank provided below the inside of the cargo hold, thereby lowering temperature of the cargo hold through cold heat of liquid nitrogen stored in the liquid nitrogen storage tank and re-liquefying boil off gas generated in the cargo hold.
액화천연가스 화물창의 기화율 저감 시스템이 개시된다. 본 발명에 따른 액화천연가스 화물창의 기화율 저감 시스템은, 액화천연가스가 저장되는 화물창; 상기 화물창 내부의 하측에 배치되는 액화질소 저장탱크;를 포함하여, 상기 액화질소 저장탱크에 저장된 액화질소의 냉열로 상기 화물창의 온도를 낮추며, 상기 화물창에서 발생하는 증발가스를 재액화시키는 것을 특징으로 한다.
