The benefits of integrated electric (full electric) or hybrid electric drive (gear-mounted or shaft-mounted motors) selections for ship propulsion include:

Efficiency and Emissions

  • Prime movers operate at most efficient, constant speed
  • Power generation equipment can be switched on and off as needed
  • Controllable pitch propellers may also be eliminated
  • Permanent Magnet Motors with high efficiencies and power factors close to 1…


  • Flexibility in locating the prime movers across the platform
  • Additional redundancy on the drive shaft
  • Hybrid Lithium ion Battery Drives with Battery Management Systems (BMS)

Reduction in Noise and Vibration

  • For all-electric, elimination of the main reduction gear
  • Hybrid electric drives makes it possible to eliminate the reduction gear
  • Both benefit from prime movers running at a constant speed

Ship Architecture Flexibility

  • Ability to send the power where needed
  • No need to align prime movers with the shafting

Maintenance Reduction

  • Reduction of the total number of prime movers
  • Elimination of controllable pitch propellers and their support systems
  • Less wear and tear on prime movers as they are operated under less stressful conditions

The Best Way to Predict the Future
