Wismar, Germany: high-level technology from the Baltic Sea

Large Dimensions

The Wismar SCHOTTEL subsidiary specializes in the development and production of particularly large propulsion systems. In a production and storage area of 15,000 square metres, propulsion units for extra powerful vessels are manufactured. Even though the site is experienced with large dimensions, each machine is impressive in its size like these customer specific versions.

SCHOTTEL RUDDERPROPELLER TYPE SRP 610

  • Input power 3,000 kW
  • Propeller diameter 3.3 m
  • Characteristics: a total of four of these electrically driven rudder propellers form the main propulsion system of a crane vessel. For over 70 years, the rudder propeller has been covering numerous configuration options and can thus be installed for a wide range of ship designs and areas of application.

SCHOTTEL RETRACTABLE RUDDERPROPELLER TYPE SRP 610 R

  • Input power 3,250 kW
  • Propeller diameter 3.0 m
  • Characteristics: the retractable unit is equipped with a propeller shaft inclined downwards by 8 degrees to reduce interactions between the propulsion units as well as between the units and the hull, 
  • and to increase propulsion efficiency. When retracted, the SRP-R functions as a fully 360-degree steerable propulsion unit. It is based on proven rudder propeller technology.

SCHOTTEL RUDDERPROPELLER TYPE SRP 710

  • Input power 3,700 kW
  • Propeller diameter 3.4 m
  • Characteristics: with input powers of up to 3,750 kW and propeller diameters of up to 3.6 metres, the SRP 710 is one of the larger rudder propellers in the SCHOTTEL portfolio. Two of the rudder propellers shown here for a salvage tug achieve a bollard pull of over 120 tonnes.

Precision performance

Controllable pitch propellers are used wherever maximum thrust and manoeuvrability at changing speeds and loads are needed. The adjustability of the propeller blades makes them particularly suitable for vessels that have to fulfil a wide-ranging operational profile. The propellers are designed according to the customer’s individual requirements using state-of-the-art calculation methods such as Computational Fluid Dynamics (CFD). Operators thus benefit from a high degree of efficiency with lower fuel and operating costs. SCHOTTEL ControllablePropellers are available in 4- and 5-blade versions with optional full-feathering function.

The new SRP-D

With the new SRP-D ("Dynamic"), SCHOTTEL is launching a rudder propeller that even better meets the increased requirements for the efficient operation of W2W vessels. Based on the proven principle of the rudder propeller, an economical yet powerful solution has been developed that greatly improves the positional accuracy of the vessel in DP operation. Operators benefit from the significant increase in performance and thus possible operating times in close proximity to offshore structures, especially in demanding weather conditions.
