Rolls-Royce Launches Light Weight Waterjet for Naval Market

Posted on February 23, 2009

Rolls-Royce has launched a new waterjet for naval markets. The Kamewa FF67 will be the latest in the FF-series of aluminium waterjets, which are the lightest and most powerful in their power range. The new waterjet, available from late 2009, will also be suitable for commercial marine and offshore markets. The company said the FF67, which will be the most powerful of the FF series, is an entirely new design incorporating built-in hydraulics for the first time. This will save installation time at shipyards and guarantee smooth start-up.

The FF67 will weigh approximately 1650 kg, including the hydraulic valve block and the redesigned axial flow pump provides more thrust over the whole speed range. This offers higher bollard pull and improved acceleration. In addition, a completely new steering nozzle, developed from the Kamewa A3 series, allows turning at high speed. An improved reversing “bucket” system provides reversing efficiency of up to 65 percent of forward thrust.

The waterjet’s lightweight design is achieved through a combination of an aluminium frame and an inlet duct manufactured from welded aluminium sheet. This production method also gives improved anti-corrosion characteristics and allows the waterjet to be customised to meet customer requirements.
