Gas-fired superconductive electrically propelled ship

Abstract

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.

1 . A gas-fired superconductive electrically propelled ship comprising a fuel tank for storing LNG, a vaporized gas feed line for feeding as fuel of vaporized gas generated in said fuel tank to driving engines for generators, a gas heater incorporated in said vaporized gas feed line for heating the vaporized gas, a propelling superconductive motor driven with electric power generated by said generators, a heat pump for cooling said superconductive motor and maintaining low temperature thereof and an LNG gasification line for feeding of LNG from the fuel tank as cold source in compression radiation treatment in said heat pump and for guiding of the vaporized gas having treated to the fuel tank and to entry-side of the gas heater in said vaporized gas feed line. 
     
     
         2 . The gas-fired superconductive electrically propelled ship as claimed in  claim 1 , wherein the LNG gasification line has cooling lines in parallel with one another and passing respectively through various devices and equipments in the ship. 
     
     
         3 . The gas-fired superconductive electrically propelled ship as claimed in  claim 1 , wherein the fuel tank is a cargo tank. 
     
     
         4 . The gas-fired superconductive electrically propelled ship as claimed in  claim 2 , wherein the fuel tank is a cargo tank.
