SCHOTTEL TWIN PROPELLER – RUDDERPROPELLER WITH TWO PROPELLERS The SCHOTTEL Rudderpropeller (SRP) has been setting standards in the field of steerable propulsion systems for decades. Proven in service worldwide, this system converts the engine power into optimum thrust power and also offers the possibility of rotating the underwater part through 360°, thus allowing the full input power to be used for manoeuvring the ship. loads. This is because the Twin Propeller technology reduces the load acting on each individual propeller by distributing the power over two propellers, thereby increasing...

MAXIMUM RELIABILITY IN ALL APPLICATIONS OFFSHORE SUPPORT VESSELS The STP produces not only higher thrust in open-water service but also higher static thrust than a single open propeller Z-drive and is thus also outstandingly suitable for offshore support vessels with dynamic positioning requirements. The low pressure fluctuations and noise emissions along with the application potential for high open-water speeds make the STP ideal for propelling yachts and passenger vessels of all types.

INSTALLATION IN THE WATER OR DRY-DOCK The STP can be installed in a dry-dock from below with the aid of a flange. When installed from below, the STP can be either bolted or welded to the flange. Installation from above is also possible, thus the unit can be installed even if the vessel is already afloat. This allows maintenance or exchange even if there is no dry-dock available.

STEERING SYSTEMS – PRECISE AND USER-FRIENDLY Propulsion systems are only as good as their steering. Optimally adapted data exchange between the different components (propulsion units and joystick or steering console) is therefore top priority. A further priority is a user interface that is as intuitive as possible, enabling safe manoeuvring even with frequent changes of master. Here too, SCHOTTEL steering systems set the course, both literally and figuratively. In close cooperation, electronics engineers and propulsion specialists develop complete steering and control systems (SST)...
