A method for maintenance of a unit which is arranged in a watertight hoisting chamber and closes an opening in a vessel hull is described. The method includes clamping of the unit in its mounted position by a clamping member so that fixing member of the unit can be removed while the unit is held clamped in position. After the hoisting chamber is flooded to a desired level, the clamping of the unit can be completely released and no unintentional movement of the unit will occur. Guide member may be provided together with the apparatus and an automatic design of the clamping member can also be provided. Preferably, the clamping member are hydraulic cylinders which press the unit into its mounted position.
