SHIP Russian patent published in 2020 - IPC B63B25/16 B63H21/38 F17C9/02 

FIELD: shipbuilding.

SUBSTANCE: invention relates to a ship including a system for repeated liquefaction of stripping gas. Disclosed is a vessel, which includes a liquefied gas storage tank and comprising: a heat exchanger for heat exchange of compressed stripping gas (hereinafter referred to as "first fluid medium") with the use of quenching gas released from the storage tank as a coolant in order to cool it; a main compression unit for compressing a portion of stripping gas, discharged from storage container; an additional compression unit provided in parallel to the main compression unit so as to compress another portion of stripping gas discharged from the storage container; and a decompression device for expanding a first fluid, cooled by heat exchange with a stripping gas, which is discharged from a storage container, in a heat exchanger, wherein the first fluid medium is: a stream in which the stripping gas is compressed, compressed by the main compression unit, and the stripping gas compressed by the additional compression unit; or a stripping gas compressed by the main compression unit.

EFFECT: invention improves efficiency of repeated liquefaction of stripping gas.
