Fact Sheet Rolls-Royce waterjets Rolls-Royce is the world leader in research, development and manufacture of high power waterjets for commercial Rolls-Royce is the only supplier in the industry with its own, fully equipped marine laboratory. In constant use, the laboratory personnel research, develop and test new products and improvements to existing ones. All Kamewa S3 series waterjets flow from the same, basic design, ensuring fast implementation of the latest product developments. Kamewa mixed-flow waterjet S3 series Kamewa waterjet propulsion concept - Excellent high speed performance - State-of-the-art control system - Superior manoeuvrability at all speeds - Shallow draught - Superior efficiency - Reduced noise and vibration levels - Increased comfort - Simple, reliable and robust construction Quality components, quality support Efficiency ratings of higher that 90 per cent stem from the mixed-flow type pumps used Built-in bearings absorb the impeller thrust, thus facilitating the inlet duct structural Each shaft-line is adapted when it comes to whirling, dimensions and weight. Minimal and simple cable installation is achieved through a new, computerized databus-based system for steering and reversing control, which can be used for both manual and joystick manoeuvring. Number and placement of stations can be customised. The system provides redundancy and real time control with a very high level of security. Stainless steel components provide long life and reliable service. Every waterjet size can also be supplied as a booster. The sale is just the beginning of a reliable partnership. Where ever you are in the world, Rolls-Royce provides a high level of service and support, including custom tailored service agreements designed to meet your individual needs. Optimised power for reduced fuel The Kamewa waterjets can be individually optimized for every installation, providing reduced fuel consumption. Nozzle diameter and impeller pitch are matched to suit the operation condition as well as matched to gearbox and engine, in ordertoabsorbfull power. And.asmanyas 10 shapes of the waterjet inlet are used to avoid flow separation and cavitation problems. Rolls-Royce utilises our own proprietary, computerised design program, which contains the latest waterjet technology, as well as actual results from earlier waterjet With the aid of this program, individua influences and the combined effect of all parameters will be studied to find the solution that provides the best fuel economy
