SYSTEM FOR SUPPLYING FUEL TO ENGINE OF SHIP

摘要

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.

主权项

1. 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 to a pressure in a range from 150 bar absolute (bar(a)) to 400 bar(a); a heater in fluid communication with the fuel pump and configured to heat pressurized fuel from the fuel pump to a supercritical state of the fuel; a supercritical fuel engine in fluid communication with the heater and configured to consume the fuel from the heater in its supercritical state; at least one hydraulic pump configured to convert mechanical power into a pressurized flow of a hydraulic fluid; a first hydraulic motor in fluid communication with the at least one hydraulic pump and configured to convert the pressurized flow from the at least one hydraulic pump into torque to power the fuel pump; a lubricant pump configured to pump lubricant to either or both of the fuel pump and the hydraulic motor; a second hydraulic motor in fluid communication with the at least one hydraulic pump and configured to convert the pressurized flow from the at least one hydraulic pump into torque to power the lubricant pump; hydraulic fluid conduits interconnecting the at least one hydraulic pump and the first and second hydraulic motors; a fuel pump compartment comprising multiple air-tight walls and enclosing the fuel pump, the first hydraulic motor and the lubricant pump and the second hydraulic motor; and at least one hydraulic pump compartment enclosing the at least one hydraulic pump, wherein the fuel pump compartment is air-tightly separated from the at least one hydraulic pump compartment such that the fuel pump, the first hydraulic motor, the lubricant pump and the second hydraulic motor are air-tightly isolated from the at least one hydraulic pump.
