The invention relates to the technical field of ships, in particular to a marine main engine oil supply system and a marine main engine oil supply method. A marine main engine oil supply system comprises a ship body, a fuel oil daily cabin, a fuel oil overhead oil tank, a main engine, an overflow pipe, an oil return pipe, a first suction port pipe, a second suction port pipe, a first valve, a second valve and a third valve, and the fuel oil daily cabin, the fuel oil overhead oil tank, the main engine, the overflow pipe, the oil return pipe, the first suction port pipe, the second suction port pipe, the first valve, the second valve and the third valve are arranged on the ship body. Therefore, it can be guaranteed that when the main engine is started at any time, design parameters of the main engine can be met, the influence of the fuel liquid level of the fuel daily cabin on the main engine does not need to be considered, meanwhile, fuel in the fuel daily cabin can be fully utilized, the situation that in order to meet the design parameters of the main engine, part of fuel in the fuel daily cabin is unavailable is avoided, and the service life of the main engine is prolonged. Therefore, the cruising ability of the ship is improved.

    本发明涉及船舶技术领域,尤其涉及一种船舶主机供油系统及一种船舶主机供油方法。一种船舶主机供油系统包括船体和设置于船体的燃油日用舱、燃油高置油柜、主机、溢流管、回油管、第一吸口管、第二吸口管、第一阀门、第二阀门以及第三阀门,通过设置燃油高置油柜的舱底高于主机的曲轴中心的1.5米处,从而能够保证在任何时候启动主机的时候,都能够满足主机的设计参数,不需要考虑燃油日用舱的燃油液面对主机的影响,同时能够充分利用燃油日用舱中的燃油,避免为了满足主机设计参数导致燃油日用舱中部分燃油不可用的情况,从而提高了船舶的续航能力。
