With one of the most technically advanced facilities in Europe, CJR Propulsion is a world leader in the design and manufacture of shafts, propellers, rudders and other associated stern gear for a variety of marine vessels, such as larger pleasure boats, ferries and other working boats.
Supported by an ongoing and extensive programme of investment, CJR houses a purpose built engineering centre - incorporating a specialised CAD/CAM design centre to produce machined, one-piece solid patterns from which extremely accurate castings can be made in the company's own advanced foundry.
CJR is also one of the world's leading CFD marine specialists, working closely with The University of Southampton, to advance the use of computational fluid dynamics in the marine industry.
About the project
CJR propulsion manufactures bespoke designs for each vessel; these are cast in their foundry on site and finished to a very high standard. The capability to produce bespoke, optimal propellers and associated stern gear packages within a commercially viable cost and timeframe presented a significant challenge.
In this KTP, CJR Propulsion worked with the University of Southampton's Engineering and the Environment unit to improve boat speed and fuel efficiency, as well as reducing the noise and vibration felt on board due to the propeller.
Benefits
- Increased energy efficiency though optimally matched propeller and associated stern gear
- Significantly reduced the potential for erosion at high speed
- Effected a step-change in the Company's business processes
