COOLING WATER CONTROL SYSTEM, METHOD, AND ARTICS VESSEL HAVING THE CONTROL SYSTEM

摘要

The present invention relates to a cooling water control system and method for an arctic vessel and an arctic vessel having the control system, which prevent damage to a seawater suction pump as seawater is sucked only by filtering ice particles contained in the seawater through multi-stage filtering, and enables the smooth supply of seawater for cooling required for a vessel even under cryogenic environment by using the seawater stored in a ballast water tank as cooling water even in a state of emergency, such as the impossible operation of an ice sea chest and a lower sea chest. The cooling water control system comprises: an ice sea chest which cuts off ice particles and sucks seawater; a cooler which performs cooling using the sucked seawater; a lower sea chest which discharges the seawater passing through the cooler; a main seawater circulation line; a first seawater pump which sucks the seawater through the ice sea chest; a ballast water tank; a ballast water sea chest which sends the seawater to the inside of the ballast water tank; a second seawater pump which sucks the seawater through the ballast water sea chest; and a ballast water circulation line.
