Kind Code:
A1
Abstract:
The present invention relates to a polar vessel having a cooling water control system using seawater to cool a heating device, the polar vessel comprising: a sea chest which takes in and stores seawater from the outside of the vessel; an engine room ballast tank formed on the hull of the vessel to store the seawater; a heating device which generates energy to operate the vessel and in which heat is generated; a heat exchanger which exchanges heat between a heat medium heated in the heating device and the seawater to cool the heat medium and heat the seawater; and a main seawater pump which supplies the seawater stored in the sea chest or the engine room ballast tank to the heat exchanger, wherein during normal times when no freezing is generated in the sea chest, the seawater flowing through the sea chest is supplied to the heat exchanger by the main seawater pump, and in the event of an emergency when freezing is generated in the sea chest, the seawater stored in the engine room ballast tank is supplied to the heat exchanger by the main seawater pump.
