ZF offers a full-spectrum hybrid propulsion solution for marine vessels, integrating hybrid-ready transmissions, electric motors, converters, and control systems. The complete hybrid system accommodates electric power inputs of 150-750 kW when adding a power-take-in (PTI) to its conventional powertrain.

The hybrid-ready transmissions span from about 600 kW up to 11,500 kW of conventional engine output, enabling retrofit or new-build applications across a wide range of vessels.

The hybrid architecture delivers multiple operation modes – fully electric, conventional diesel, boost, generator – allowing for optimized performance, reduced fuel consumption, lower emissions, and quieter operation, especially in ports or sensitive areas. Its modular PTI configuration and compact design facilitate easier integration, whether for new ship designs or upgrading existing platforms. View options:

ZF’s POD 4900 model integrates propulsion, steering, and hybrid drive components into a unified, high-efficiency module designed for larger vessels. Its hybrid-capable transmission system includes a Power-Take-In (PTI) option that enables an auxiliary electric motor to augment or replace diesel power during low-load, maneuvering, or emissions-sensitive operations. This allows ships to run in all-electric mode when appropriate, reducing fuel consumption, lowering emissions, and improving onboard comfort.

The system’s design emphasizes compactness and integration: the combined propulsion and steering functions reduce system complexity while delivering precise maneuverability. Its hybrid configuration ensures seamless interaction between the electric motor and primary drive, making it an effective solution for vessels needing both high performance and cleaner operation in demanding marine environments.

This series marks a major step in supporting the marine industry’s transition to fully electric propulsion. The first product, the ZF 3000 ENC, delivers exceptional power density and efficiency, with a noise-, vibration-, and efficiency-optimized design suited for high-rpm electric drives. Available across all ZF configurations from ZF 2000 to ZF 9000, including sub-configurations, the ENC series strengthens ZF’s portfolio that already serves fuel-based and hybrid vessels. It answers rising market demand for cleaner propulsion solutions, providing shipyards, operators, and vessel owners with advanced electric options.

Engineered to maximize the efficiency of high-rpm electric motors, ZF ENC transmissions optimize power transfer to the propeller, reducing energy use while enhancing range and operational economy. Their lightweight construction further lowers battery demand and operating costs, making them a practical and sustainable solution for demanding marine applications.

The Azimuth Thruster (AT) series is the latest line from ZF. This well-mounted, Z-Drive thruster is compatible with a wide range of commercial vessels, including commercial fishing vessels. It supports a maximum power of 100 kW to 2,500 kW, increasing the power and thrust capabilities of the previous product line. Fully customizable to nearly any hull shape or vessel profile, the ZF AT series is one of the most flexible products on the market.

All thrusters in ZF’s AT series can be executed as part of a hybrid or fully electric system, requiring reduced engine power during vessel operation, full electric sailing, dynamic positioning and slow cruising while in electric mode, and more. Operators who install the AT series aboard vessels are one step closer to earning a CLEANSHIP class notation.

The new hybrid ZF AT product family uses an electric motor placed at the upper gearbox’s Power-Take-In (PTI) whose performance is tailored to the individual vessel type and application. Said applications include professional vessels ranging from tugs and pushers, ferries, research vessels, supply boats and others. It allows for full electric sailing and maneuvering, which is especially useful in ports or waterways with strict emission and noise regulations. It can also be used as an additional booster, for instance when evading obstacles or increasing the top speed with the additional electric power. When used in firefighting purposes, the hybrid setup eliminates the necessity for a more expensive controlled pitch propeller. Here, the diesel engine and electric motor will separately drive the firefighting pump and thruster, respectively.

Further adding to its sustainability scorecard: the ZF AT 80 is equipped with a special seal arrangement designed for biodegradable oil (EAL). Set up in a L-drive configuration such as a retractable or tunnel thruster, the ZF AT 80 is also available as a purely electrically driven solution. Additionally, extra features – like an integrated brake or a Power-Take-Off (PTO) – make the ZF AT 80 the perfect solution for a variety of use cases.
