  • Patent number: 10655852
    Abstract: This ship includes a ship body, a fuel tank chamber, a stern-side engine room, a bow-side engine room, a main fuel line and a sub-fuel line, and a pump mechanism. The main fuel line connects a fuel tank, a stern-side power generation unit, and a bow-side power generation unit through the bow-side engine room. The sub-fuel line connects at least the fuel tank and the stern-side power generation unit, and is disposed through a section different from the bow-side engine room through which the main fuel line passes. The pump mechanism selectively feeds fuel into the main fuel line or the sub-fuel line from the fuel tank.
