Abstract: The mounting of a thruster propeller unit (18) in the bottom plating (23) of a vessel is facilitated by the use of lifting lines (26), operable from within the vessel. Each line is made to pass a lock chamber (27) adjacent to an opening in the bottom plating, outside the opening where the thruster propeller is to be fitted. The lock chamber (27) includes a first, rigid tubular member (35), which is formed as the housing for a slide valve (36), as well as a second tubular member (37), which is resilient at least in the transverse direction. The two tubular members define a passage being substantially wider than the diameter of the lifting line (26). The second tubular member (37) is at its top provided with a sealing sleeve (42) which fits around the line. The locking chamber is connected to a source (44) of compressed air, which makes it possible to maintain a pressure within the chamber balancing the pressure of the surrounding water.
