The design is mainly used for barges. , floating cranes, ferries and work boats, but can also be used to propel any floating project.
The propulsion unit's prime mover can use a MAN or Caterpillar diesel engine with a clutch between the engine and the Rudderpropeller that can transmit power through the flexible coupling and the universal joint shaft. The propeller can be raised and dropped in the vertical direction and can be swung back. There are three basic variants of this series of propulsion units, namely NAV Basic, NAV Offshore and NAV soundproof, all with manual ventilation for the galvanized outer casing Offshore and the Soundproof. The propulsion unit uses a low-emission engine with a power range of 190 kW from NAV0320 to 746 kW for the NAV550.
