Abstract: 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.

Abstract: A method of reducing thermal stresses of a semiconductor component in a frequency converter, an arrangement in a frequency converter, and a frequency converter, wherein the semiconductor component is attached to a cooling element for cooling the semiconductor component and one or more resistive elements are attached to the cooling element. In the method, the cooling element is heated by the one or more resistive elements attached thereto by supplying current from the frequency converter through the one or more resistive elements for obtaining an elevated lowest temperature for the semiconductor component and thereby reducing the amount of temperature change between the highest and the lowest temperatures in the semiconductor component during use of the frequency converter.
