Marine Electric Power & Propulsion

Power Conversion has a range of electric ship technologies to provide a reliable, integrated power and propulsion solution. From smaller support vessels to the largest crane ships, and the latest cruise ships and tankers, solutions include integrated electric drive or hybrid-electric systems. Both are enablers of improving energy efficiency and decarbonization on our customers’ fleets and helping to comply with the latest energy-efficiency regulations and reporting. 

Power Conversion ’s electric propulsion systems on-board electric power supplies and networks, energy management, automation, control, dynamic positioning and digital technologies work together seamlessly to supply a ship’s full power requirements, including energy-efficient propulsion, service loads and energy-intense operating systems

  • Both low voltage (LV) and higher, MV architectures, optimized for space and efficiency
  • 1-40MW systems (scalable to 120MW)
  • Safe and resilient
  • Easy to configure, install, commission and maintain
  • Deep understanding of marine applications and class standards, including cyber security and ice-class operation

Marine electric power & propulsion

  • Ship’s Electric Grid is hugely versatile, just as suited to smaller ships as the biggest transport and deep water offshore vessels.

  • Simplicity and flexibility from being able to combine power for propulsion and on-board equipment in one connected system.

  • Electric and podded propulsion meets the needs of high maneuverability and thrust requirements, with up to 10%fuel-efficiency improvements.

  • Ideal to help future-proof growing power demands across the ship’s life, e.g. to accommodate new operational equipment.

  • Best solution to ‘plug-in’ future power technologies and fuels, for example a mix of clean energy sources.

Hybrid electric solutions

  • Cost-effective choice for vessels with lower, but variable energy demands for on-board systems.

  • Able to retain conventional mechanical drive configuration, but supplement available energy and help to reduce emissions.

  • Power take-off / power take-in (PTO/PTI) shaft generators are ideal for space-constrained applications, diverting excess main engine power to ships’ service loads.

A range of other hybrid configurations is available. Find out more in our Energy Efficiency & Decarbonization solutions.
