aid the development of the new propellers. Using lifting surface theory, integrated with computational fluid dynamics, CJR has been able to test the new propeller designs and predict a vessel’s performance in realistic conditions with an extremely high degree of accuracy. A number of the M-R-K Superprop designs have
now been installed and trialled with good results. In each individual test, the performance of the vessel fitted with the M-R-K Superprop has been dramatically transformed. In addition, the vessel’s fuel efficiency and range has significantly increased. The most impressive aspect of these trials has been the accurate correlation between CJR’s predicted data and the actual test data.
The future New additions to the company include a purpose- built state-of-the-art engineering facility and a pattern making facility. Alongside this is the planned expansion of the company’s second manufacturing site, with new offices, storage areas, and design space; and later, a propeller repair centre to be named CJR ‘South West’. Meanwhile, plans are being made to open an Italian office, with an aim of breaking into the huge potential market in Italy. There are also plans to improve website functionality
via 3D drawing library (IGES files) through a secure area; downloadable quality documentation (individual prop test certificates); and an online order processing/ progressing facility. Customers will benefit from a move to robotic
finishing, bar coded part tracking, closer collaboration with engine manufacturers for better first trial acceptance, and boxed deliveries. SBI
