TWIN DISC 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


This parallel hybrid system is capable of generating electricity for hotel loads. It’s most suitable for vessels with long waits between jobs (e.g., tugs, pilot boats, workboats in general, military vessels, and yachts), and for those operating in restricted areas and zero-emission zones. Twin Disc technology enables implementation into any standard marine transmission.



SYSTEM OVERVIEW

  • Parallel hybrid using diesel and electric power
  • During low-power operation, the e-motor can use excess diesel power to generate electricity for hotel load, allowing the hotel load generator to be shut down
  • In high-demand phases, electric power can boost diesel power

MARINE TRANSMISSION

  • Based on standard marine transmission, with same footprint and selection criteria, for worldwide support
  • No trailing pump needed; transmission is lubricated as diesel or e-motor drives it
  • Efficient design minimizing losses

MASTERCLUTCH™

  • Provides power generation through PTO/PTI in forward, neutral, and reverse
  • Prevents engine back-driving during electric-only operation
  • Allows all features of QuickShift® transmission

PTI GEARBOX

  • Drives transmission primary shaft (same as engine) with MasterClutch™ providing disconnect
  • Allows for standard speed/smaller e-motor through motor speed reduction
  • Offset to propeller shaft enables installation of large motors
  • Reductions from 1.0:1 to 2.5:1
  • Integrated sea water pump cools transmission during electric propulsion
  • PTO available for onboard hydraulics (e.g., steering pump)

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, HIGH VOLTAGE EQUIPMENT

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

DIESEL + ELECTRIC WITH ENERGY STORAGE


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

This parallel hybrid system uses standard Twin Disc propulsion control. It’s best suited for vessels with long waits between jobs, high percentage of slow speed operation, and operating in restricted areas and zero emission zones. Twin Disc technology enables implementation into any standard QuickShift® marine transmission.



OVERVIEW

  • Parallel hybrid using diesel and electric power
  • During low-power operation, the e-motor uses excess diesel power to generate electricity
  • In high-demand phases, electric power can boost diesel power

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

DIESEL + SINGLE ELECTRIC MOTOR WITH ENERGY STORAGE (VETH)

This parallel hybrid system uses Veth azimuth thrusters and propulsion control system. It’s best suited for short-trip vessels such as ferries and tugs, and for vessels operating 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

AZIMUTH THRUSTER

  • Dual input for diesel engine and electric motor
  • Most components identical to standard azimuth thruster for worldwide support
  • Same footprint and selection criteria as standard azimuth thruster
  • Full range of models available

CONTROLLERS

  • Veth standard propulsion control and operator interface
  • Manages / controls power distribution, interfacing with the engine, thruster, and high voltage equipment

HYBRID CONTROLLER

  • Manages power distribution, interfacing with propulsion controller and high voltage equipment

E-MOTOR/INVERTER & STORAGE

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

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

LOOKING FOR THE RIGHT ELECTRIC & HYBRID SOLUTION FOR YOU?

GET TO KNOW YOUR OPTIONS


FULL ELECTRIC

The Full Electric System eliminates the main diesel engine and its maintenance costs, and cuts fuel costs and emissions. Configurable power-dense energy storage systems efficiently provide the energy needed to power the application.

SERIAL ELECTRIC

The Serial hybrid system uses an electric motor to replace the traditional main diesel engine, drawing electric power from an onboard energy storage system, onboard gensets, or both.


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.
