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.
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.
As the industry’s technical leader, we have invested heavily in advanced technology and recognise the importance of steering the industry towards a more scientific approach to hull and associated appendage design. We also see the potentially significant commercial gains which can be made through having a better understanding of the underwater environment.
