SHIP Russian patent published in 2019 - IPC B63B25/16 F25J1/00 F17C9/02 F17C6/00 B63H21/38 F02M21/02 

FIELD: vessels and other watercrafts.

SUBSTANCE: invention relates to shipbuilding, particularly, to vessels using gas fuel engine. Disclosed are a vessel, which includes a tank for storing liquefied gas, and a system for treating stripping gas for a ship. In particular, most or all of remaining stripping gas can be repeatedly liquefied without using cooling cycle, and using separate cooling agent, and therefore increasing economic efficiency. It is possible to flexibly control flow rate of coolant flow and supply of heat released during cooling in compliance with output quantity of stripping gas, load on engine depending on working speed of ship. In particular, the heat exchanger of the coolant can use not only the stripping gas compressed by the additional compressor, but also the stripping gas compressed by the compressor, as coolant for increasing flow rate of stripping gas used as coolant in heat exchanger of coolant, even more improving efficiency of repeated liquefaction and quantity of repeatedly liquefied stripping gas.

EFFECT: invention makes it possible to increase efficiency of repeated liquefaction and quantity of repeatedly liquefied stripping gas, since the flaking gas is decompressed after the process of additional cooling with the help of a heat exchanger of cooling agent.
