Abstract: An arrangement and a method for sealing a propeller shaft of a marine vessel. The arrangement includes a propeller shaft rotatable supported with at least one bearing, a bearing arrangement, a first lubrication arrangement including a first lubricant circulation line for conducting first lubricant to and from the bearing arrangement, a shaft seal arrangement for sealing the propeller shaft against sea water, and a second lubrication arrangement including a second lubricant circulation line for conducting second lubricant to and from the shaft seal arrangement. A first heat exchanger is in thermal contact with the first lubricant circulation line and in thermal contact with the second lubricant circulation line.
