GAS-POWERED SUPERCONDUCTIVELY ELECTRICALLY PROPELLED SHIP

摘要

A gas-fired superconductive electrically propelled ship is provided with a cargo tank 1 (fuel tank) for storage of LNG 2, a vaporized gas feed line 3 for feeding of vaporized gas 2' produced in the cargo tank 1 as fuel to dual-fuel engines (driving engines) 5 for generators 6, a gas heater 4 incorporated in the vaporized gas feed line 3 for heating of the vaporized gas 2', a propelling superconductive motor 7 driven with electric power produced by the generator 6, a heat pump 15 for cooling the superconductive motor 7 and maintaining low temperature of the motor and an LNG gasification line 26 for feeding of LNG 2 from the cargo tank 1 as cold source for compression radiation treatment in the heat pump 15 and for guiding of the vaporized gas 2' having treated to the cargo tank 1 and to the vaporized gas feed line 3 at entry-side of the gas heater 4.
