According to one embodiment of the present invention, provided is a vessel for polar navigation. The vessel for polar navigation is capable of preventing a seawater inlet from being frozen even when a large quantity of seawater in a scrubber is discharged to the outside of the vessel. According to one embodiment of the present invention, the vessel for polar navigation includes: a hull having a seawater inlet and a seawater outlet; a sea chest connected to the seawater inlet, separated from an inner space of the hull, and forming a storage space storing the seawater; a seawater circulation pipe having both ends each connected to the sea chest to circulate the seawater stored in the sea chest to the sea chest through the inner space; a cooler installed in the inner space, connected to the seawater circulation pipe, and exchanging heat of the seawater and heat of pure water circulating in a combustion engine so as to cool the pure water; a heater installed in the inner space, connected to the seawater circulation pipe at a rear end of the cooler, and heating the seawater returning to the sea chest; the scrubber installed in the inner space and spraying the seawater supplied from the sea chest to exhaust gas discharged from the combustion engine; and a seawater discharge pipe connecting the scrubber and seawater outlet to discharge, to the outside of the hull, the seawater coming into contact with the exhaust gas in gas and liquid states by the scrubber.

    본 발명의 일 실시예에 의해 극지 운항용 선박이 제공된다. 본 발명의 일 실시예에 따른 극지 운항용 선박은, 해수유입구와 해수유출구가 형성된 선체와, 해수유입구와 연결되고 선체의 내부공간과 분리되며 해수를 저장하는 저장공간을 형성하는 씨체스트와, 양단이 각각 씨체스트에 연결되어 씨체스트 내부에 저장된 해수를 내부공간을 경유하여 다시 씨체스트로 순환시키는 해수순환관과, 내부공간에 설치되며 해수순환관에 연결되어 연소기관을 순환하는 청수와 해수를 열교환하여 청수를 냉각하는 냉각기와, 내부공간에 설치되며 냉각기 후단의 해수순환관에 연결되어 씨체스트로 귀환하는 해수를 가열하는 가열기와, 내부공간에 설치되며 연소기관에서 배출되는 배기가스에 씨체스트로부터 공급받은 해수를 분무하는 스크러버, 및 스크러버와 해수유출구를 연결하여 스크러버에서 배기가스와 기액 접촉한 해수를 선체 밖으로 직접 배출하는 해수배출관을 포함할 수 있다.
