As the world leader in waterjet propulsion, Rolls-Royce provides solutions for customers around the world. Our Kamewa waterjets power the smallest inshore craft up to the largest ferries and the latest high speed naval craft.
Medium-sized waterjets with stainless steel mixed flow technology with aluminium inlet duct/hydraulics. Powers up to 2.8MW with pump diameters 36-56cm.
Medium and small-sized aluminium waterjets with flexible axial flow technology with aluminium inlet duct/hydraulics. Powers up to 1.8MW with pump diameters 24-67cm.
Large waterjets with stainless steel mixed flow technology and optimised inlet duct design. Powers 1-40MW with pump diameters 45-200cm.
Extra large waterjets with stainless steel mixed flow technology. Powers above 27MW with pump diameters over 200cm.
Waterjets are in a class of their own because of their versatile operating characteristics, which permit easy and accurate control of the craft at all speeds and in waters too shallow for vessels with conventional propulsion systems.
At high speeds, the unrivalled efficiency of Kamewa waterjet propulsion offers either a greater top speed or better fuel economy. No reversing gearbox is required, stopping distances are short and craft can turn on the spot or even manoeuvre sideways.
