Customer requirements

Baudouin pure marine engines are known worldwide for their reliability and durability in a challenging marine environment. We are committed to designing marine powertrains that reduce exhaust emissions and control fuel consumption at any running cycle. In synergy with our sister companies, Baudouin experts have developed environmentally-conscious hybrid systems to answer complex customer requirements.

Partnership With Experts

Being part of the Weichai group allows Baudouin to leverage technological expertise with our sister company Aradex and other marine hybrid specialists, to be able to provide a fully integrated hybrid solution for marine applications. Together, we offer our marine customers, tailored systems that perfectly match their requirements.

Hybrid Configuration

Series Hybrid with Genset

Utilizing onboard electrical generation systems, batteries can be charged and then discharged through onboard electrical motors to allow for low noise and zero-emissions operation. Efficiency improvements through optimal loading of the generators can improve fuel consumption, service costs, and exhaust emissions allowing reduced running hours and full electric operation.

Parallel Hybrid with inline Electric Motor

A diesel engine is connected via a clutch and gearbox to the propeller in a standard propulsion system. Also connected in parallel to the gearbox is an electric motor and battery pack, enabling the system to switch between an electric drive or a standard diesel motor. During operation the engine can be used to recharge the batteries which are then discharged to improve overall system efficiency, reducing fuel consumption and allowing for zero-emissions running.

Our Hybrid References

Alcatraz Clipper

The Alcatraz City Cruises Hybrid Ferry Fleet has redefined the profile of vessels on San Francisco Bay. As the nation’s first hybrid passenger ferry service, our fleet’s mission is far more important than its appearance. When the solar panels on top of the vessels absorb sunlight and energy is generated by the wind turbines, power is provided to charge the 12V DC batteries. Additional power is provided by diesel generators for more efficient movement through the water. Each of the hybrid vessels in Alcatraz City Cruises Fleet can operate on propulsion batteries alone for over an hour, providing a silent cruise around San Francisco Bay.

Alcatraz City Cruises, with our hybrid passenger ferry fleet, is leading the way in environmentally-friendly vessels and decreases our carbon footprint daily. The Alcatraz Clipper is one of the cruise’s passenger tourism vessels that have been powered by a Baudouin 6M26.3 P2 diesel propulsion engine. Hornblower Cruises and Events trusted Baudouin on this project for the great engine torque in 16L, good warranty and flexible technical solution.
