Serial Hybrid (Veth): Single Electric Motor with Generator Power & Energy Storage

This serial hybrid system uses a Veth azimuth thruster and propulsion controller. It optimizes fuel use through multiple gensets and is best suited for vessels (e.g., river-cruise vessels, super and mega yachts, survey vessels, dredgers, and ferries) operating in restricted areas and zero-emission zones.

System Overview

  • Serial hybrid using electric power
  • Optimizes fuel use via gensets operating at the top of their fuel efficiency range. When propellers operate at low power, some gensets can be switched off, and the rest continue in their optimal range.
  • Machinery compartments can be located to optimize cargo space or meet class requirements

Azimuth Thruster

  • Ultra-low-profile electric motor integrated into azimuth thruster
  • Underwater 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 propulsion controller and high voltage equipment

E-Motor

  • Selection based on application characteristics (e.g., torque, RPM range, voltage, DU/DT filter pressure)

Inverter, High Voltage Equipment

  • Controlled and monitored by alarm and monitoring system

Energy Storage & BMS

  • Selection based on application characteristics

Generator

  • May be supplied by Twin Disc
