SHIP Russian patent published in 2020 - IPC B63B25/16 F17C9/02 F17C6/00 

FIELD: vessels and other watercrafts.

SUBSTANCE: invention relates to the field of shipbuilding, in particular, to a ship including a system which repeatedly liquefies the stripping gas formed in the storage tank. Vessel comprises multi-stage compressor for compression of stripping gas discharged from storage tank, containing multiple compression cylinders; a second heat exchanger for performing heat transfer of fluid medium, compressed by multi-stage compressor, and, consequently, its cooling; first decompression device for flow expansion (hereinafter referred to as flow a1) partially branched from flow (hereinafter referred to as flow a) cooled by second heat exchanger; third heat exchanger for performing heat exchange using flow a1 expanded by first decompression device, as flow coolant (hereinafter referred to as flow a2), remaining from flow a after elimination of branched flow a1, and, consequently, its cooling; and second decompression device for expansion of flow a2 cooled by third heat exchanger, wherein the second heat exchanger cools the fluid medium compressed by the multi-stage compressor using the flow a2 expanded by the second decompression device as the coolant.

EFFECT: possibility of more efficient repeated liquefaction of stripping gas.
