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 with E-Motor

  • 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 Control System

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

Inverter, High Voltage Equipment

  • Controlled and monitored by alarm and monitoring system
  • Selection based on application characteristics

Energy Storage

  • Controlled and monitored by alarm and monitoring system
  • Selection based on application characteristics
