Rudder & Propulsion Controls — Industry Leaders in Marine Manoeuvring
Germany has long been a powerhouse in maritime engineering, and its ship steering systems sector is no exception. From precision rudders to azimuth thrusters and integrated propulsion controls, German manufacturers set the global benchmark for reliability, efficiency, and innovation. This guide profiles the five key players driving the industry forward.
Modern vessel manoeuvring demands far more than a simple rudder and wheel. Today’s steering systems integrate electro-hydraulic actuators, advanced autopilot algorithms, dynamic positioning interfaces, and highly efficient propulsion-steering combos. German companies supply everything from coastal workboats to the world’s largest container ships and luxury yachts. Below we examine the leading manufacturers headquartered in Germany, their core technologies, and what sets them apart in a competitive global market.
Rolls-Royce Power Systems, home to the MTU brand, delivers fully integrated bridge-to-propeller solutions through its mtu NautIQ product family. This covers steering control, autopilot functions, and dynamic positioning for naval vessels, super-yachts, and offshore support ships. By combining engine management with rudder and thruster controls into a single automation platform, MTU enables optimal fuel efficiency and manoeuvrability across the entire operating envelope. The Friedrichshafen facility houses extensive R&D capabilities including simulation labs that test steering response under extreme sea states.
Becker Marine Systems is the world leader in high-performance rudder technology. Its flagship Becker Flap Rudder uses a servo-driven trailing-edge flap to generate up to 70 % more side force than a conventional spade rudder, delivering tighter turning circles and reduced stopping distances for ferries, Ro-Ro vessels, cruise ships, and mega-yachts. Becker also manufactures the Becker Twisted Fin and the Becker Mewis Duct, a pre-swirl stator that recovers rotational energy from the propeller slipstream to cut fuel consumption by 4–6 %. With over 6,000 rudder installations worldwide, Becker Marine Systems is synonymous with rudder innovation.
Jastram Engineering has designed and built steering gear for more than 80 years, specialising in electro-hydraulic steering systems for vessels from 10 m workboats up to 400 m tankers and bulk carriers. Its modular Jastram Steering Gear System (JSG) can be configured for single-rudder, twin-rudder, or multi-rudder arrangements without custom engineering. Jastram also supplies the Jastram Monitoring System (JMS), a digital condition-monitoring suite that tracks oil quality, cylinder leakage, and bearing wear in real time, helping operators shift from calendar-based to predictive maintenance.
Schottel invented the azimuth thruster and remains the global technology leader in steerable propulsion. Its Schottel RudderPropeller (SRP) combines a controllable-pitch propeller with a 360°-rotatable pod, providing both propulsion and steering thrust from a single unit and eliminating the need for a separate rudder. The product line spans the compact SCD for inland push-boats to the SRP 7000 series for offshore construction vessels. Schottel also produces the Schottel Pump Jet (SPJ) for high-speed naval craft and the Schottel EcoPeller, a permanent-magnet azimuth thruster that reduces noise and maintenance while boosting efficiency.
Wärtsilä’s German operations supply integrated steering and propulsion control systems under the Wärtsilä NACOS platform, encompassing autopilots, track-pilot control, dynamic positioning, and full bridge automation. The company’s German engineering centres specialise in transverse thrusters, tunnel thrusters, and retractable azimuth thrusters that work with main steering systems for precise station-keeping. Wärtsilä Germany also drives smart steering development, including machine-learning-based autopilot tuning that adapts to sea state, hull fouling, and loading conditions without manual recalibration.
The German steering systems market is defined by three converging trends:
Germany’s steering manufacturers command a significant global market share, particularly in cruise, LNG carrier, naval, and offshore wind installation vessels. Exports account for over 80 % of production, with key customer regions in Asia, the Middle East, and Northern Europe. The country benefits from a dense network of classification societies, research institutes, and a highly skilled workforce. According to the VDMA Marine & Offshore Industries association, steering and manoeuvring systems represent roughly 12 % of Germany’s marine equipment exports, a share that has grown steadily as vessel sizes increase and port congestion demands ever-better low-speed manoeuvring capability.
German manufacturers produce the full spectrum: conventional spade and semi-spade rudders, high-lift flap rudders (Becker), rotary-vane and ram-type electro-hydraulic steering gear (Jastram), azimuth thrusters that combine propulsion and steering (Schottel), and fully integrated bridge-control platforms with autopilot and dynamic positioning (Rolls-Royce/MTU and Wärtsilä Germany). Most systems are available in electric, electro-hydraulic, and hybrid configurations.
For tugs and harbour craft, Schottel’s RudderPropeller (SRP) or the Becker Flap Rudder paired with a Jastram JSG steering gear are industry-standard choices. Schottel azimuth thrusters offer 360° thrust vectoring for exceptional responsiveness during ship-assist operations, while Becker flap rudders provide high side-force for robust course control in narrow channels. Many operators combine both an SRP for primary propulsion and a flap rudder for emergency backup and enhanced seakeeping.
German manufacturers support decarbonisation through multiple technologies. Becker’s Mewis Duct and Twisted Fin reduce fuel consumption by recovering rotational energy. Schottel’s EcoPeller uses permanent-magnet technology to cut electrical losses by 30 % compared to conventional induction motors. MTU’s NautIQ platform enables optimal engine loading via precise steering and trim control. Most manufacturers now offer all-electric steering gear variants that eliminate hydraulic oil, reducing fire risk and potential for accidental discharge. These technologies help vessel owners comply with IMO EEXI and CII regulations.
Yes, retrofitting is a major part of the business. Jastram’s modular JSG steering gear fits existing rudder stocks with minimal structural modification. Becker offers retrofit kits for flap rudders that install during scheduled dry-docking. Schottel provides compact azimuth thruster units mountable through bottom or side flanges, often replacing older nozzle-rudder arrangements. Wärtsilä Germany supplies bridge-automation retrofits that integrate with legacy steering gear. Typical payback periods range from two to four years based on fuel savings alone, making retrofits a sound investment without the cost of a new build.
