ZF expands maritime propulsion portfolio with hybrid transmission & thruster

ZF is expanding its maritime propulsion portfolio with the introduction of newly engineered hybrid transmissions and heavy-duty thrusters designed to support both commercial and specialized marine operations.

The rollout of these maritime driveline systems focuses on integrating hybrid propulsion configurations and high-capacity thruster units into various vessel segments. These structural components are engineered to support the exact operational requirements of commercial transport, passenger ferries, and specialized offshore marine craft.




Modular hybrid transmission architecture for variable vessel layouts
The ZF 9200 A/V PTI represents the latest hardware integration into the manufacturer's hybrid transmission series. This specific driveline system incorporates a power take-in (PTI) module, which allows shipbuilders to connect electric motors directly to the main transmission shaft. This mechanical configuration supports diesel-electric or fully electric propulsion modes, accommodating a wide range of engine room constraints and custom vessel parameters. By standardizing the interface between the combustion engine and the electric drive system, the transmission facilitates lower-emission maneuvering in regulated port environments.




High-performance thruster integration for marine maneuverability
Alongside the transmission modules, the introduction of the ZF AT 110 thruster expands the physical driveline hardware available to naval architects. Thruster systems of this scale provide localized directional thrust independent of the main forward propulsion system. This application improves dynamic positioning and low-speed maneuverability for large-displacement hulls, reducing reliance on external tug vessels during docking procedures. The complete range of propulsion hardware, along with accompanying digital monitoring services, is scheduled for presentation at the SMM trade fair in Hamburg, Germany, from September 1 to 4, 2026, located in Hall A3, Booth 219.

The ZF 9200 A/V PTI transmission and AT 110 thruster compete directly in the commercial marine propulsion sector against systems from manufacturers such as Twin Disc, Schottel, and Kongsberg Maritime. In the hybrid marine transmission market, benchmarking relies on maximum input torque capacity, gear reduction ratio flexibility, and the mechanical efficiency of the PTI integration for electric motor coupling. While traditional mechanical drivetrains rely solely on internal combustion, hybrid-ready transmissions are evaluated based on their ability to switch seamlessly between diesel and electric power modes without mechanical power loss or excessive thermal generation. Thruster units like the AT 110 are typically measured by their continuous bollard pull ratings, hydrodynamic efficiency of the propeller housing, and the spatial footprint required for structural hull mounting.
