Disclosed are a liquefied gas bunkering system and a liquefied gas bunkering method using the same. According to an embodiment of the present invention, the liquefied gas bunkering system includes: a liquefied gas supply line connecting a storage tank of a bunkering vessel with a fuel tank of a propelling ship, and supplying liquefied gas stored in the storage tank to the fuel tank; a spray line branched from the liquefied gas supply line to be connected with the fuel tank, and spraying the liquefied gas supplied through the liquefied gas supply line into the fuel tank through a spray means; a first valve provided on the liquefied gas supply line; a second valve provided on the spray line; a pressure measurement part separately measuring the internal pressure of the fuel tank and the internal pressure of the storage tank; and a control part, if the internal pressure of the fuel tank exceeds the internal pressure of the storage tank by no less than a set value, gradually closing the first valve and opening the second valve so as to lead the liquefied gas supplied from the storage tank to be sprayed into the fuel tank through the spray line, and gradually increasing the flow rate of a pump provided in the storage tank. Therefore, the present invention is capable of effectively reducing the production of evaporation gas in the fuel tank.

    액화가스 벙커링 시스템 및 이를 이용한 액화가스 벙커링 방법을 개시한다. 본 발명의 실시 예에 따른 액화가스 벙커링 시스템은 벙커링 선박의 저장탱크와 추진선박의 연료탱크를 연결하며, 저장탱크에 저장된 액화가스를 연료탱크로 공급하는 액화가스공급라인; 액화가스공급라인으로부터 분기되어 연료탱크와 연결되며, 액화가스공급라인을 통해 공급된 액화가스를 스프레이수단에 의해 연료탱크 내부로 분사시키는 스프레이라인; 액화가스공급라인에 마련된 제1밸브; 스프레이라인에 마련된 제2밸브; 저장탱크와 연료탱크의 내부 압력을 각각 측정하는 압력측정부; 및 측정 결과 연료탱크의 내부 압력이 저장탱크의 내부 압력보다 설정값 이상을 초과한 경우, 점차적으로 제1밸브를 폐쇄시키고 제2밸브를 개방시켜 저장탱크로부터 공급된 액화가스가 스프레이라인을 통해 연료탱크 내부로 분사되도록 하고, 저장탱크 내부에 마련된 펌프의 유량을 점차적으로 늘리는 제어부;를 포함한다.
