A fuel handling system in a cargo tank of a ship is disclosed. The fuel handling system in a cargo tank of a ship according to an embodiment of the present invention comprises: a heat exchanger that heats boil-off gas supplied from a storage tank storing liquefied gas and the boil-off gas thereof, or converts a phase of the liquefied gas into a gaseous component; a boil-off gas heating line that sends the boil-off gas supplied from the storage tank to the heat exchanger; and a liquefied gas vaporization line that sends the liquefied gas supplied from the storage tank to the heat exchanger. The fuel handling system may send the boil-off gas supplied from the storage tank to the heat exchanger through the boil-off gas heating line, and supply the same into the storage tank after the boil-off gas is heated during warm-up work for the inside of the storage tank. During pressure maintenance work for the inside of the storage tank, the fuel handling system may send the liquefied gas supplied from the storage tank to the heat exchanger through the liquefied gas vaporization line to change the phase thereof to the gaseous components, and then supply the same into the storage tank.
선박 화물창의 연료처리시스템을 개시한다. 본 발명의 실시 예에 따른 선박 화물창의 연료처리시스템은 액화가스 및 이의 증발가스를 저장하는 저장탱크로부터 공급받은 증발가스를 가열시키거나 액화가스를 기체성분으로 상변환시키는 열교환기; 저장탱크로부터 공급받은 증발가스를 열교환기로 보내는 증발가스가열라인; 및 저장탱크로부터 공급받은 액화가스를 열교환기로 보내는 액화가스기화라인;을 포함하되, 저장탱크 내부에 대한 웜업 작업 시에는 저장탱크로부터 공급받은 증발가스를 증발가스가열라인을 통해 열교환기로 보내어 가열시킨 후 저장탱크 내부로 공급하고, 저장탱크 내부의 압력 유지 작업 시에는 저장탱크로부터 공급받은 액화가스를 액화가스기화라인을 통해 열교환기로 보내어 기체성분으로 상변환시킨 후 저장탱크 내부로 공급할 수 있다.
