New RIM Thruster from Schottel
German propulsion specialist Schottel extends his product range with a RIM Thruster (SRT)
Noise and low-vibration drives, highly efficient, space-saving, weight-reduced and eco-sensitive are particularly requested at ships, which are operating very often in DP mode or if special comfort is required. With the Schottel RIM Thruster (SRT) the German propulsion specialist extends his product range with four sizes (200 – 800 kW).
The SRT is an all electrical drive system without gear or drive shaft. The stator of the electric motor is mounted into the outer part of a tunnel. Blades are attached to the inside of the rotor. According to Schottel the SRT is a drive propulsion system capable of transmitting the electric power directly into propulsion without any transfer loss of gears and without noise emission caused by a gear box. The optimized hydrodynamic design, with the blades inside, results into a remarkable reduction of cavitation.
The design of the Schottel RIM thruster is moreover robust and easy to maintain. The highly efficient electric motor is cooled by the surrounding water. In case of damages the blades can be simply exchanged. Even the water lubricated plain bearings are easily accessible in case of maintenance, which is a further contribution for cost reduction.
The new Schottel SRT is available via the worldwide Schottel sales network as of 2013. For inland vessels and luxury yachts sales takes place via dutch based Van der Velden Marine Systems.
The customer benefits of the Schottel RIM thruster summarized: powerful, ecofriendly, low-vibration, compact design, water lubricated bearings, exchangeable blades and exchangeable plain bearings.
