Schottel delivers 1,000th SRP 460

The SRP 460 (formerly SRP 1515) was launched in 1999 with its first delivery going to Danish tug operator Svitzer for installation on the harbour tug Mussandam. The two original SRP 460 thrusters originally installed have been in operation for more than 20 years and still provide the vessel, now operating as VB Muleton for Spanish shipping company, Boluda, with manoeuvrability and bollard pull.

With a maximum power rating for tug duties of up to 2,350kW per engine, the SRP 460 has undergone several technical updates to increase input speeds and propeller diameter. The latest update also led to the development of the Schottel Rudderpropeller type SRP 490, the enlarged version of the SRP 460, with a propeller diameter of up to 2.80m and a tug duty of up to 2,550kW per engine.

Universal all-rounder

The SRP 460 is also available in a number of other forms. These include the Schottel Combi Drive, in which the electric motor is integrated vertically into the rudder propeller, as well as the Schottel Twin Propeller and Rudder EcoPeller.

In addition, the recently introduced Schottel hybrid azimuth propulsion systems, SYDRIVE-E and SYDRIVE-M, offer unlimited flexibility in any hybrid vessel design. With these systems, new upper gears for all input rpm enable optional hybrid propulsion as well as flexible installation variants for all hull forms.
