Parallel Hybrid

Parallel Hybrid System pairs the diesel engine with an electric motor. This configuration takes advantage of both, allowing for diesel-only, electric-only, peak shaving, and power boost operation.

Diesel + Electric Motor with Generator Power

Diesel + Electric Motor With Energy Storage

Best suited for vessels with long waits between jobs, slow speed operation, and operating in restricted areas.

Diesel + Single Electric Motor with Energy Storage (Veth)

This traditional diesel-electric propulsion system uses a Veth azimuth thruster and propulsion control system. It’s best suited for vessels operating in restricted areas and zero-emission zones.

Diesel + Dual Electric Motors with Energy Storage

Parallel Hybrid

Diesel + Dual Electric Motors with Energy Storage

This parallel hybrid system features dual electric motors per drivetrain. It’s best suited for vessels such as mid-size passenger vessels, patrol boats, or workboats/fishing boats requiring higher electric power to accomplish their duty cycle in restricted areas and zero-emission zones.
Overview
  • Parallel hybrid using diesel and electric power
  • During low-power operation, the e-motor can use excess diesel power to generate electricity
  • In high-demand phases, electric power can boost diesel power
RePTO Drive w MasterClutch™
  • Installed between diesel engine and E-Motor/generator providing mechanical interface to direct-mount E-Motors/generators
  • Supports all features of QuickShift® transmission
  • Permits power generation through PTO/PTI in forward, neutral and reverse
  • Prevents engine back-driving during electric-only operation
Transmission
  • Based on standard marine transmission, with same footprint and selection criteria and proven worldwide support
  • No trailing pump needed; transmission is lubricated as diesel or e-motor drives it
  • Efficient design minimizes losses
Controller

Propulsion Controller

  • Twin Disc standard propulsion controller and operator interface

Hybrid Controller

  • Manages power distribution, interfacing with propulsion controller and high voltage equipment
E-MOTOR/INVERTER & STORAGE

E-Motor/Inverter, High Voltage Equipment/Energy Storage

  • Selection based on application characteristics
  • Controlled and monitored by hybrid controller
