New SCHOTTEL M-series: Efficient SRE available in medium-size

With medium-sized azimuth thrusters, SCHOTTEL meets new challenges on the international maritime market. These include shifted engine power classes, new ice class rules and the growing trend towards electric or hybrid drive vessels. Combining the latest technologies in mechanical engineering, hydrodynamics, and digitalization, the medium-sized thrusters are available in three sizes corresponding to the common engine power classes: SRE 210 (640 kW) and SRE 270 (1,000 kW).
Suitable for any vessel type and application
These new SCHOTTEL M-series azimuth thrusters offer the right solution for any vessel type and application with a range of various power source options and input directions. The azimuth modules are available for Z-drives, L-drives and ZY-hybrid drives, making them suitable for horizontal electric, vertical electric or combined direct engine plus horizontal electric motor connection. Thus, the M-series thrusters are also compatible with hybrid solutions – such as SCHOTTEL SYDRIVE.
No vessel design modifications required
Thanks to two basic installation variants, the M-series works with any type of vessel design. Besides the standard installation with variable propeller arm length, a compact minimized variant with shorter propeller arm length is available. These compact installation variants (LC for L-drives, ZC for Z-drives) open up new scope and greater design freedom for ship designers, while leaving more space for other equipment. Both the standard and the compact variant can be bolted, welded or resiliently mounted on vessels.
Great versatility
The new SCHOTTEL M-series features a modular system that allows for multiple configuration options. Great versatility and flexibility in the medium power range, high reliability, optimal spare part availability, and good retrofit options – all combined with the best propulsion efficiency thanks to latest hydrodynamic optimization and mechanic design.

EcoPeller sets standards as a highly efficient thruster

The SCHOTTEL Rudder EcoPeller (SRE®, EcoPeller®) offers outstanding overall propulsion efficiency and excellent course-keeping stability, enabling low fuel consumption and low operating costs and low emissions.


Ship owners are facing major ecological and economical challenges to meet the ever stricter requirements of emission quotas and environmental regulations. At the same time, the technical requirements of customers, such as maximum overall efficiency, excellent course keeping stability and exact positioning in DP operation, are significantly influencing shipbuilding.


SCHOTTEL is meeting these developments with a highly efficient and ecologically clean propulsion system developed primarily for open sea and coastal operating conditions: the SCHOTTEL Rudder EcoPeller. 


The SRE combines proven SCHOTTEL quality and technology with the latest, hydrodynamic insights from CFD simulations and model tests. The SRE is based on the SCHOTTEL Combi Drive design principle: The electric motor is vertically integrated into the support tube of the EcoPeller. This design saves space and eliminates the upper of the two angle gears as well as any necessary shaft lines. Thus, the EcoPeller also offers unbeatable comfort thanks to extremely low vibration and low noise levels.


Additionally, the integrated High-Torque-Gear (HTG) technology provides enhanced durability and uptime of the thruster, while the LEACON sealing system guarantees highest oil-to-water-interface protection. For more technical information


The EcoPeller is currently leading the Norwegian ferry market as it has been selected to be installed in eight newly-built ferries of two of the biggest Norwegian ferry lines. Read more about the references
