MARINE VESSEL, RELIQUEFYING SYSTEM, AND METHOD FOR RELIQUEFYING BOILOFF GAS IN MARINE VESSEL

摘要

PROBLEM TO BE SOLVED: To provide a marine vessel which efficiently uses boiloff gas and fuel oil, a reliquefying system, and a method for reliquefying the boiloff gas in the marine vessel.;SOLUTION: One part of fuel oil and boiloff gas is burned by a boiler 23 to generate vapor, and a vapor turbine 26 is driven by the vapor into working energy of a refrigerant in a reliquefying device 30. The fuel oil and the boiloff gas are flexibly used according to cost balance of the fuel oil and the boiloff gas. The vapor generated by burning one part of the fuel oil and the boiloff gas is heated using waste heat of exhaust gas of a diesel main machine 10 and a diesel generator 11.;COPYRIGHT: (C)2004,JPO
