What Becker Marine Systems does

Becker Marine Systems GmbH is a Hamburg-based, privately held maritime technology company that designs, manufactures, and services hydrodynamic components for commercial and naval ships. Its portfolio spans three product families: manoeuvring systems (Becker Flap Rudder, Twist Rudder, Schilling Rudder, Nozzle, Rotary Vane and Cylinder Type Steering Gear, the newer Daggerboard anti-leeway fin, and rudder options), energy-saving devices (the proprietary Becker Mewis Duct and Becker Twisted Fin, which optimize propeller inflow to reduce fuel burn and CO2 emissions), and monitoring systems (BIMS and BBMS). The company also provides service, repair, conversion, spare parts, training, and underwater imaging to its installed base.

The firm's commercial model is B2B enterprise hardware sales: products are specified at shipyard design stage for new-build vessels and retrofitted during dry-docking for in-service ships. Distribution combines seven wholly-owned offices — Hamburg (HQ and engineering), Shanghai and Zhenjiang (China manufacturing via Becker Marine Systems JiangSu Co. Ltd.), Busan, Gjerdrum (Norway), Singapore (Asia regional HQ), and Houston — with more than 15 agencies spanning Africa, Asia, Australia, the Baltics, Europe, and South America to deliver 24/7 service. Pricing is quote-based and not publicly disclosed.

Becker reports products installed on more than 9,000 ships globally, including 2,132 vessels with the Mewis Duct and 924 with the Twisted Fin (both tracked since 2010), and claims cumulative CO2 reductions above 25 million tonnes. Customer segments span container, tanker, bulk carrier, gas carrier, passenger/cruise, ferry, navy, and — most recently — wind-assisted propulsion. Since April 2021, Japanese propeller maker Nakashima Propeller holds a strategic stake and acts as the company's Japan sales agent. The company holds ISO 9001:2015, ISO 14001:2015, ISO 27001:2022, and DNV GL (for COBRA) certifications and has won the German Environmental Prize (2022) and dual Ship Technology Excellence Awards (2025).

Products and services

• Becker Flap Rudder High-performance rudder solution designed to maximise ship manoeuvrability while enhancing performance and efficiency; sold to shipyards for newbuilds and ship owners for retrofits on tankers, container ships, ferries, cruise ships and other large vessels.
• Becker Twist Rudder Innovative rudder solution aimed at maximising manoeuvrability of ships while enhancing hydrodynamic performance and efficiency; for newbuild and retrofit commercial ship customers.
• Becker Schilling Rudder Advanced rudder system designed for superior ship handling and manoeuvring capabilities; intended for commercial vessels and ships where high-performance manoeuvring is required.
• Becker Nozzle Propulsion system component that optimises water flow to the propeller for improved efficiency, used on vessels such as supertankers where high-propulsion efficiency is critical.
• Becker Rotary Vane Steering Gear Space-saving rotary vane steering system with eight variants covering 160KNm–500KNm torques for smaller commercial vessels such as supply vessels, fishing boats, and yachts.
• Becker Cylinder Type Steering Gear Steering gear solution for precise vessel manoeuvring and control, used on commercial ships requiring reliable steering systems.
• Becker Daggerboard Anti-leeway fin that counteracts side forces and stabilises a vessel's course, enabling ships with wind-assisted propulsion systems to fully benefit from wind power without compromising efficiency or manoeuvrability.
• Becker Mewis Duct Proprietary energy-saving duct installed ahead of the propeller to optimise inflow, reducing energy consumption and lowering CO2 emissions on commercial vessels.
• Becker Twisted Fin Energy-saving appendage that optimises propeller inflow to lower fuel consumption and CO2 emissions, used on commercial ships alongside or as an alternative to the Mewis Duct.
• Becker Intelligent Monitoring System (BIMS) Digital monitoring system that improves safety and performance by minimising stall conditions and rudder movements on vessels equipped with Becker rudders and energy-saving devices.
• Becker Bearing Monitoring System (BBMS) System for monitoring bearing conditions in Becker rudder installations to ensure optimal performance and prevent failures.
• COBRA Battery System DNV GL certified maritime battery system for versatile use in inland and seagoing shipping applications, achieving the highest safety standard.

Direct peers

• Schottel GmbH & Co. KG: Schottel is a direct competitor in marine propulsion and manoeuvring equipment — particularly rudder propellers and full manoeuvring systems for ships. Highly comparable niche: hydrodynamic ship manoeuvring hardware sold to shipyards and shipowners worldwide.
• Brunvoll AS: Brunvoll is a direct competitor manufacturing thrust and manoeuvring systems including azimuth thrusters and controllable pitch propellers for commercial shipping and offshore. Closely comparable in product category (ship manoeuvring hardware) and target customers (yards and shipowners).
• Berg Propulsion: Berg Propulsion manufactures controllable pitch propellers and propulsion efficiency systems for commercial shipping. Directly comparable product category (propulsion hardware and efficiency devices) and customer base (shipyards, shipowners seeking fuel-efficiency upgrades).

Broad incumbents

• Kongsberg Maritime: Kongsberg Maritime is a broad incumbent supplying propulsion, manoeuvring, automation, and monitoring systems to commercial and naval shipping. Comparable because it overlaps Becker in steering controls, hydrodynamics, and vessel monitoring — but as part of a much larger portfolio.
• Wärtsilä Corporation: Wärtsilä is a broad marine-industry incumbent providing ship power, propulsion, and efficiency solutions including lifecycle services. Comparable as a marine systems vendor addressing similar decarbonization and efficiency priorities, though vastly larger and more diversified than Becker.
• ABB Marine & Ports: ABB Marine & Ports is a broad incumbent offering electric propulsion, automation, and integrated ship systems that compete with — and complement — Becker's steering, propulsion efficiency, and monitoring portfolio. Overlaps with Becker's IMO-driven efficiency/decarbonization value proposition.
• ZF Marine Technology Center: ZF supplies marine driveline, transmissions, and steering systems for commercial and pleasure craft. Comparable in addressing the same shipyard and vessel manoeuvring categories, though via gear/transmission rather than rudder-centric manoeuvring solutions.
• Alfa Laval Marine: Alfa Laval is a broad marine equipment incumbent supplying separators, heat exchangers, boilers, and increasingly energy-efficiency and emission-reduction systems. Comparable because it serves the same shipowner/shipyard channel addressing EEXI/CII compliance, though broader in scope.

Others

• Nakashima Propeller: Nakashima Propeller is Becker's strategic parent (acquired stake April 2021) and a Japanese propeller manufacturer that combines integrated propeller + rudder/energy-saving sales with Becker. Listed here because Nakashima overlaps with Becker's hydrodynamic efficiency solutions and acts as sales agent in Japan — but is no longer a direct competitor.

Emerging players

• Caley Ocean Systems: Caley supplies winches, specialised deck machinery, and bespoke marine handling equipment to commercial and offshore clients. Comparable as a niche marine-systems supplier, though focused on deck machinery rather than propulsion/manoeuvring like Becker.
