Independent‑Driven Technology Empowers Ship Electrification
Technical Breakthroughs & Industrial Contributions of Fuber 250kW Azimuth Pod Propulsor

Against the backdrop of global shipping’s accelerated green‑low‑carbon transition and deepening domestic substitution for high‑end marine core equipment, high‑power azimuth pod propulsors, as the key power core for new‑energy vessels, have long been monopolized by overseas manufacturers. This has restricted the independent development of domestic electric workboats, offshore wind service vessels, official research ships and other ship types. Fuber’s self‑developed 250kW azimuth pod propulsor delivers critical technical breakthroughs, filling the gap for medium‑high‑power domestic electric pod propulsion products and writing an important chapter for the independent innovation of China’s marine propulsion industry.

Core Technical Breakthroughs, Solving Multiple Engineering Challenges

Conventional ship propulsion systems rely on long transmission shafts, gearboxes and independent rudders, suffering from large transmission losses, high cabin space occupation and limited maneuverability. Breaking the constraints of traditional architectures, Fuber 250kW azimuth pod propulsor highly integrates high‑power permanent‑magnet motor, propeller, sealing protection and slewing servo mechanism inside the underwater pod unit. It realizes 360‑degree unlimited azimuth vector propulsion, combining propulsion and steering functions into one unit.

For the power unit, the product adopts high‑power‑density underwater permanent‑magnet direct‑drive motor, greatly shortening the transmission chain and eliminating gear‑driven losses. Its propulsion efficiency is about 20 % higher than traditional propulsion systems, and vessel maneuverability is improved by 40 %. Facing harsh marine conditions of high salinity and high hydrostatic pressure, the R&D team overcame key technical challenges including high‑power underwater dynamic sealing, high‑torque slip‑ring, fluid‑thermal coupled heat dissipation and cavitation‑suppressing hydrodynamic optimization. Stable long‑term underwater operation is achieved with effectively suppressed vibration and noise, lowering equipment failure rates and improving onboard comfort.

Powered by self‑developed integrated control system, this pod supports CAN‑bus digital communication and seamless connection with ship autopilot. Real‑time monitoring of rotating speed, temperature, azimuth angle and fault early‑warning are available, providing a reliable underlying power actuator for smart and unmanned vessels. Its modular design simplifies installation and facilitates convenient maintenance without frequent dry‑docking, effectively reducing the vessel’s whole‑life‑cycle operational cost.

Industrial Contributions: Breaking Monopolies & Expanding Application Boundaries of Domestic Propulsion

For years, the medium‑high‑power pod propulsion market has been dominated by foreign suppliers, featuring high procurement costs, long lead times and constrained local technical support, hindering large‑scale deployment of domestic new‑energy commercial ships. The launch of Fuber 250kW azimuth pod propulsor delivers a fully independent and controllable technical solution, breaking overseas technical barriers. It fills the domestic product gap in the 250 kW electric pod propulsion segment, completes the domestic marine electric propulsion portfolio, offers cost‑effective local alternatives for shipyards and mitigates construction costs as well as supply‑chain risks for new‑energy vessels.

In terms of application scenarios, it is well‑suited for offshore wind service vessels, port workboats, large inland electric cruise ships, official research vessels and more. Thanks to outstanding maneuverability including spot turning and sideways berthing, vessels depend less on tugboats when operating in narrow harbors and complex waters, significantly boosting operational efficiency. Its high‑efficiency characteristic cuts energy consumption and carbon emissions, aligning with shipping’s green‑emission‑reduction goals and accelerating electrification of inland and coastal waterborne transportation.

Industry Value: Empowering Maritime‑Power‑Building Strategy

Beyond the success of a single piece of equipment, technical accumulation from this product delivers complete engineering experience covering motor design, sealing, hydrodynamic simulation, system control and full‑scale verification for domestic high‑power pod propulsion technology. It builds a reusable technical foundation for future iteration of higher‑power pod propulsion products.

Driven by China’s maritime‑power‑building strategy, offshore development, offshore new‑energy industry and green shipping embrace huge market potential. Represented by the 250 kW azimuth pod propulsor, domestic equipment from Fuber pushes China’s marine propulsion industry from “following‑behind” toward “running‑parallel”. It strengthens the high‑end marine propulsion industrial chain and injects continuous momentum into high‑quality development of green and smart shipping.
