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…
Survivability
- 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
