Schottel is a globally trusted manufacturer of innovative propulsion and maneuvering systems for all types of vessels, known for their reliability, efficiency, and high maneuverability. At Serden Ship Supply Marine Electric & Electronics Ltd., we specialize in the installation, commissioning, and service of Schottel propulsion systems including rudder propellers (SRP), transverse thrusters (STT), pump jets (SPJ), and eco-friendly hybrid propulsion units.

With over 30 years of marine engineering expertise, our team ensures that every Schottel system we install meets the highest standards of performance, safety, and class compliance.

 What Is a Schottel Propulsion System?

Schottel systems offer 360° maneuverability, efficient power transfer, and flexible integration for a wide range of marine applications. Their portfolio includes:

• SRP (Schottel RudderPropeller): Azimuth propulsion with steerable drive

• STT (Schottel TransverseThruster): Bow and stern thrusters for port maneuvering

• SPJ (Schottel Pump Jet): Compact, non-protruding propulsion ideal for shallow draft vessels

• SCD (Schottel Controllable Propeller): Highly efficient with adjustable pitch

• Hybrid and electric drives: Environmentally friendly systems for modern fleets

These systems are ideal for offshore vessels, ferries, tugs, workboats, tankers, and more.
