An apparatus and a method for sealing a propeller shaft (1) of a marine vessel are disclosed. The apparatus comprises: a propeller shaft (1) supported by at least one bearing (2) to be rotatable, a bearing device (3), a first lubrication device (4) including a first lubricating oil circulation line (5) for guiding first lubricating oil to and from the bearing device (3), a shaft sealing device (7) for sealing the propeller shaft (1) against seawater, and a second lubrication device (8) including a second lubricating oil circulation line (9) for guiding second lubricating oil to and from the shaft sealing device (7). A first heat exchanger (11) is in thermal contact with the first lubricating oil circulation line (5) and is in thermal contact with the second lubricating oil circulation line (9). Therefore, the apparatus and a method for sealing a propeller shaft (1) of a marine vessel can reduce the temperature of the lubricating oil in the shaft sealing device, decrease the consumption of lubricating oil used in the shaft sealing device, thereby reduce wear of the shaft sealing device.
