Abstract
A system for supplying fuel to an engine of a ship. The system includes a high pressure pump pressurizing a liquefied natural gas (LNG) and supplying the pressurized LNG to the engine, a hydraulic motor driving the high pressure pump and a chamber carrying the high pressure pump and the hydraulic motor. The chamber is substantially free of electric sparks.
Claims20
A ship comprising:
- at least one fuel tank containing fuel;
- a fuel pump in fluid communication with the at least one fuel tank and configured to pressurize fuel from the at least one fuel tank;
- a heater in fluid communication with the fuel pump and configured to heat pressurized fuel from the fuel pump;
- an engine in fluid communication with the heater and configured to consume the fuel from the heater;
- a fuel pump compartment enclosing the fuel pump and a hydraulic motor for powering the fuel pump such that fuel from the at least one fuel tank is pressurized within the fuel pump compartment, wherein no electric motor is enclosed within the fuel pump compartment;
- and
- a fuel processing compartment enclosing the heater such that the pressurized fuel travels from the fuel pump compartment to the fuel processing compartment and is heated within the fuel processing compartment,
- wherein the fuel pump compartment is air-tightly separated from the fuel processing compartment by at least one air-tight wall such that the fuel pump and the hydraulic motor are air-tightly isolated from the heater.
