Disclosed is a fuel supply method for a crude oil carrier. In accordance with the present invention, the fuel supply method for a crude oil carrier, which is provided for a vessel carrying crude oil and equipped with an engine supplied with LNG as fuel, includes the following steps of: storing liquefied volatile organic compounds (LVOC) made by liquefying volatile organic compounds (VOC) generated from the crude oil; gasifying and mixing the LVOC with natural gas forcibly gasified or naturally gasified from the LNG to supply mixed gas fuel to the engine; and, when switched to a mixed gas fuel mode, supplying the forcibly gasified or naturally gasified natural gas at the beginning of a mode switching operation while checking the temperature of a fuel supply pipe, and then, supplying the mixed gas fuel, thereby preventing the generation of a condensate in the pipe. Therefore, the present invention is capable of preventing an engine failure caused by the inflow of a condensate.

    원유운반선의 연료공급방법이 개시된다. 본 발명의 원유운반선의 연료공급방법은, 원유(Crude oil)를 운반하며 LNG를 연료로 공급받는 엔진이 마련된 선박에서, 원유에서 발생하는 휘발성유기화합물(Volatile Organic Compounds, VOC)을 액화시킨 LVOC(Liquefied Volatile Organic Compounds)를 저장하고, 상기 LVOC를 기화시켜 LNG로부터 강제기화 또는 자연기화된 천연가스에 혼합하여 상기 엔진에 혼합 가스 연료를 공급하되, 혼합 가스 연료 모드로 전환 시, 모드 전환 운전 초기에 강제기화 또는 자연기화된 천연가스를 공급하면서 연료공급용 배관의 온도를 확인한 후 상기 혼합 가스 연료를 공급하여 배관 내 컨덴세이트(condensate) 생성을 방지하는 것을 특징으로 한다.
