Schottel propeller

The SCHOTTEL Twin-Propeller (STP) is the successful optimization of the complete Rudderpropeller system with an efficiency up to 20% higher. It is the ideal means of propulsion for all vessels in the medium speed range with application-related higher propeller loads.Two propellers mounted on a common shaft and rotating in the same direction, with guide fins integrated into the complete system, result in a host of advantages, including high reliability due to the straightforward construction with a small number of moving parts, reduction of the propeller diameter without penalising the efficiency, lower fuel costs and low maintenance requirements.

SCHOTTEL Rudderpropellers (SRP) are combined propulsion and steering systems rated at up to 6000 kW, which convert the engine power into optimum thrust. As the underwater components can be steered through 360 degrees, the full propulsive power can also be used for manoeuvring and dynamic positioning of the ship. Maximum manoeuvrability, optimum efficiency, economical operation, space-saving installation and simple maintenance - these are just a few of the outstanding features of this robust and reliable propulsion concept, which has proved its worth under tropical and arctic conditions in vessels of all kinds all over the globe.

The SCHOTTEL Controllable Pitch Propeller (SCP).

SCHOTTEL has developed a new concept that combines the main technical and economic criteria of both mechanical Rudderpropellers and pod drives: the SCHOTTEL Combi Drive (SCD). In contrast to pod drives with an electric motor inside the underwater pod, the motor in the new propulsion system will be integrated vertically into the support tube of the Rudderpropeller. This arrangement of the electric motor means that the concept is similar to that of a Rudderpropeller with a vertical power input (“L system”). Moreover, neither an above-water gearbox nor a cardan shaft will be required, making the system extremely compact and easy for the shipyard to install in the vessel. The SCHOTTEL Combi Drive will be based on the successful Rudderpropeller types SRP 1515, SRP 2020 and SRP 3030, with their proven mechanical components, and will cover the power range from 1900 to 3800 kW with propeller diameters from 2500 to 3500 mm. The azimuth steering can be implemented using either hydraulic or electric motors. The new drive will be available as single propeller version with nozzle or twin propeller version.
