FUEL SUPPLY SHIP CAPABLE OF OPTIMIZING THE USE OF EVAPORATIVE GAS IN CASE OF CHARGING FUEL

摘要

PURPOSE: A fuel supply ship is provided to prevent the waste of residual liquefied natural gas because the liquefied natural gas remaining in a manifold line or a loading line is heated by a heating device and is collected toward a compressive tank through a vent line.;CONSTITUTION: A fuel supply ship(100) comprises a storage tank(101), a loading line(120), a main pump(130), a spray pump(140), a vent line(123), and a heating device(123). The storage tank stores liquefied natural gas through manifolds(12). The loading line is arranged in the outside of the storage tank. The main pump is installed inside the storage tank to be connected to a discharge line(121) and supplies the liquefied natural gas to a fuel tank(11) of a liquefied natural gas propulsion ship. The spray pump is installed inside the storage tank to be connected to the end of a first spray pump line(122) and supplies some of the liquefied natural gas to a spray device(13) of the fuel tank.;COPYRIGHT KIPO 2012
