The present disclosure relates to sealing the propeller shaft of a ship using a sealing having a group of lip seals arranged consecutively in a direction of the propeller shaft so that a seal chamber is created between adjacent lip seals. The pressure of the first seal chamber on the propeller side can be close to the pressure of the surrounding water at the propeller shaft level, and the pressure of the second seal chamber furthest from the propeller can be adjusted to a fixed value that is lower than the pressure of the first seal chamber. The pressure of a third chamber located between the first chamber and the second chamber can be adjustable by pressure regulation devices to a value between the pressure values of the first and the second chambers by adjusting the pressure loss caused by the flow of a liquid medium.
