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.

Description

technical field [0001] The present invention relates to an arctic vessel comprising a cooling water control system and a cooling water control method for said arctic vessel, and more particularly to an arctic vessel comprising ensuring cooling of seawater even when ice formation occurs on the vessel in an arctic environment A smooth supply cooling water control system for arctic ships and a cooling water control method for said arctic ships. Background technique [0002] Concern has grown over the Northeast Passage near Russia and the Northwest Passage near Canada amid Arctic sea ice loss due to global warming. [0003] Since the Arctic region is rich in natural resources and is also known as an emerging tourist destination, the Arctic shipping lanes for sightseeing tours and transportation and supply of resources from Arctic oil fields are being actively developed. [0004] Specifically, countries near the Arctic Ocean, including the United States, Canada, Russia, Denmark,...
