A ship's engine is cooled by fresh water circulated in contact with the hull skin 2 in the manner of a falling-film heat exchanger, thereby transferring heat to the water 1 in which the ship floats, without bringing such water aboard. The fresh water is drawn up from a tank in the bottom of the hull by a pump 4, 12 and circulated through the engine jacket via an atmospheric break/surge tank 5 or tundish 11 to an inlet header 7, 14 of a falling-film heat exchanger formed by the hull skin 2. After flowing down the hull skin, the water returns to the tank for recirculation. <IMAGE> |
