BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifeboat storage system for a ship, and more particularly, to a lifeboat storage system for a ship in order to enable a lifeboat to be launched smoothly in a cold region such as an arctic region.

Generally, a lifeboat is installed on a ship so that the crew can escape by using a lifeboat in an emergency. These lifesaving boats include a davit launching system in which a lifesaving boat is lowered from a ship using a crane installed on the deck in accordance with a method of getting to the water surface and a davit launching system in which a lifeboat is sloped down to a free fall ) Method. However, when a ship is sailing in a cold region such as the polar region, the lifeboat is directly exposed to the low temperature outside air, and therefore, the equipment necessary for launching the lifeboat is frozen, which makes it difficult to operate properly. Korean Patent Laid-Open Publication No. 10-2012-0043794 discloses a lifeboat storage system having a storage space for storing a lifeboat to prevent the lifeboat from being directly exposed to outside air.
