Abstract:
A vessel includes a heat exchanger for heat-exchanging compressed boil-off gas (hereinafter, referred to as “first fluid”) by using, as a refrigerant, the boil-off gas discharged from a storage tank, to cool the same; a main compression part for compressing a part of the boil-off gas discharged from the storage tank; a rest compression part provided in parallel to the main compression part so as to compress the other part of the boil-off gas discharged from the storage tank; and a decompression device for expanding the first fluid having been cooled by exchanging heat with the boil-off gas, which is discharged from the storage tank, in the heat exchanger. The first fluid is a flow in which the boil-off gas compressed by the main compression part and the boil-off gas compressed by the rest compression part join; or the boil-off gas compressed by the main compression part.

Claim (Index 7):
A method wherein, in an initial stage of system operation, boil-off gas discharged from a storage tank is bifurcated into two flows, followed by sending one of the two flows to a main compression unit while sending the other flow to an extra compression unit;\n as the boil-off gas compressed by the main compression unit and the boil-off gas compressed by the extra compression unit join with each other and start to be supplied to a heat exchanger after the initial stage of system operation, the boil-off gas discharged from the storage tank is sent to the heat exchanger; the boil-off gas discharged from the storage tank and having passed through the heat exchanger is bifurcated into two flows, followed by sending one of the two flows to the main compression unit while sending the other flow to the extra compression unit; the boil-off gas compressed by the main compression unit and the boil-off gas compressed by the extra compression unit are joined with each other, followed by sending some part of the joined boil-off gas to an engine while sending the other part of the joined boil-off gas to the heat exchanger, a fluid cooled in the heat exchanger through heat exchange with the boil-off gas discharged from the storage tank is reliquefied through expansion by a decompressor, and the reliquefied fluid is separated into a gas phase and a liquid phase by a gas-liquid separator such that the liquefied gas is returned to the storage tank and the boil-off gas remaining in the gas phase is joined with the boil-off gas discharged from the storage tank to be sent to the heat exchanger.
