Hybrid Modes

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.
