Parallel Hybrid (Veth): Diesel + Single Electric Motor with Energy Storage

This parallel hybrid system uses a Veth azimuth thruster and propulsion controller. It’s best suit-ed for short-trip vessels such as ferries and tugs with sufficient shore time to charge batteries, and for vessels operating in restricted areas and zero-emission zones.

System 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

Propulsion Controller

  • Veth standard propulsion control and operator interface

Selection Panel / Hybrid Controller

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


  • Selection based on application characteristics (e.g., torque, RPM range, voltage)

Inverter, High Voltage Equipment

  • Controlled and monitored by alarm and monitoring system

Energy Storage & BMS

  • Selection based on application characteristics

Diesel Engine

  • Not supplied by Twin Disc
