WE Tech's Shaft Generator Systems For Energy Efficiency

shaft generator uses the mechanical energy of a vessel’s main propulsion shaft to produce electrical power for onboard use. Instead of relying primarily on auxiliary generators, the shaft generator converts the rotational motion of the main engine into electricity, reducing fuel consumption and emissions while improving overall energy efficiency.  

This approach is especially beneficial for ships with large propulsion engines, where the main engine already operates efficiently across a range of speeds. By integrating directly with the propulsion system, the shaft generator becomes a core part of the ship.

Why Choose WE Tech’s Shaft Generator Technology?

At WE Tech Solutions, our shaft generator systems are built on advanced permanent-magnet machine technologyvariable frequency drives and integrated energy management systems that optimise power flow onboard.  

Our solutions: 

  • Deliver significant reductions in fuel consumption and operating costs by shifting electrical generation to the main engine.  
  • Lower emissions and supports compliance with IMO decarbonisation rules such as CII and EEXI.  
  • Improve system reliability and flexibility with fewer auxiliary generator running hours and better energy distribution.  
  • Provide fast return on investment as reduced fuel and maintenance costs outweigh initial project expenditure.  

 

Our solutions emphasise compactness, efficient integration and minimal impact on existing propulsion system dynamics, making it suitable for both new builds and retrofit projects.

How the Shaft Generator Works 

Unlike conventional auxiliary gensets, a shaft generator takes mechanical input from the ship’s propeller shaft and converts it into electrical power for the ship.
This means:

Electricity is generated as the vessel moves, reducing reliance on generator sets that burn additional fuel.

Auxiliary engine running hours are minimised, which lowers maintenance and fuel costs.

Stable power is available for hotel loads, navigation systems, thrusters and other electrical consumers.

Modern shaft generators can be integrated with power electronics and DC-link distribution systems to match electrical output precisely to onboard demand, maximising efficiency across all operating conditions.

Application Scenarios

Our shaft generator solutions support a wide range of vessel types and operational profiles: 

  • Efficient electrical generation during normal service to reduce auxiliary genset usage. 
  • Boost mode operations, where the system can act as a motor to support propulsion in demanding situations.  
  • Safe return propulsion and auxiliary drive modes, improving redundancy and safety.  
  • Retrofit installations that modernise existing fleets and extend vessel lifecycles.
