The invention relates to the technical field of LNG transport ships, in particular to a fuel management method for an LNG transport ship, which comprises the following steps: a fuel controller of the LNG transport ship identifies the navigation state of the LNG transport ship; the fuel controller determines the BOG fuel demand quantity of the LNG transport ship; the fuel controller identifies a first BOG flow value of fuel in a cargo hold of the LNG transport ship in a natural evaporation state, and when the first BOG flow value is larger than or equal to the BOG fuel demand quantity, the LNG transport ship sails under the first BOG flow value; and when the first BOG flow value is smaller than the BOG fuel demand quantity, the LNG transport ship starts a forced evaporator to evaporate fuel to a second BOG flow value, the sum of the first BOG flow value and the second BOG flow value is larger than or equal to the BOG fuel demand quantity, and the LNG transport ship sails under the first BOG flow value and the second BOG flow value. The utilization rate of fuel is increased.
本发明涉及LNG运输船技术领域,尤其涉及一种LNG运输船的燃料管理方法,包括如下步骤:LNG运输船的燃料控制器识别LNG运输船的航行状态;燃料控制器确定LNG运输船的BOG燃料需求量;燃料控制器识别LNG运输船的货舱中燃料在自然蒸发状态下的第一BOG流量值,当第一BOG流量值大于或等于BOG燃料需求量时,LNG运输船在第一BOG流量值下航行;当第一BOG流量值小于BOG燃料需求量时,LNG运输船开启强制蒸发器以蒸发燃料至第二BOG流量值,第一BOG流量值和第二BOG流量值的总和大于或等于BOG燃料需求量,LNG运输船在第一BOG流量值和第二BOG流量值下航行。本发明提高了燃料的利用率。
