Spay, Germany, based propulsion specialist Schottel has delivered the first units of a new series of medium-sized azimuth thrusters.

The M-series consists of several rudder propeller sizes covering a power range of 400 to 1,000 kW. Its modular system ensures the perfect fit for any vessel design.

With the M-series, Schottel addresses new challenges in the market that include shifting engine power classes, updated ice class rules and an ever-increasing number of electric or hybrid-driven vessels.

The M-series azimuth thrusters, which combine the latest advncements in mechanical engineering, hydrodynamics and digitalization, are available in three sizes: 210 (640 kW), 240 (850 kW) and 270 (1,000 kW), corresponding to common engine power classes.

All sizes are equipped with a powerful planetary steering gear.

Schottel says that the 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. In addition to 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) offer 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.

DIFFERENT PROPULSION MODULES

Two different propulsion modules ensure that the M-series can be used for multiple operation profiles. The proven Schottel Rudderpropeller (SRP) is universally suitable for all standard applications and vessel designs, achieving high bollard pull and maximum propulsion efficiency for vessels with medium speeds.

The Schottel EcoPeller (SRE) ensures outstanding propeller performance in terms of overall efficiency and course stability in more demanding applications and when running at higher service speeds, for example, with ferries. The SRE reduces both fuel consumption and emissions, leading to lower operating costs.

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.
