Rolls-Royce waterjets

nnnn

Kamewa S3 series

nnnn

Rolls-Royce is the world leader in

nnnn

research, development and manufacture

nnnn

of high power waterjets for commercial

nnnn

and naval markets.

nnnn

Rolls-Royce is the only supplier in the

nnnn

industry with its own, fully equipped

nnnn

marine laboratory. In constant use, the

nnnn

laboratory personnel research,

nnnn

develop and test new products and

nnnn

improvements to existing ones.

nnnn

All Kamewa S3 series waterjets flow

nnnn

from the same, basic design, ensuring

nnnn

fast implementation of the latest

nnnn

product developments.

nnnn

Kamewa mixed-flow waterjet S3 series

nnnn

Kamewa waterjet propulsion concept

nnnn

provides

nnnn

- Excellent high speed performance

nnnn

- State-of-the-art control system

nnnn

- Superior manoeuvrability at all speeds

nnnn

- Shallow draught

nnnn

- Superior efficiency

nnnn

- Reduced noise and vibration levels

nnnn

- Increased comfort

nnnn

- Simple, reliable and robust construction

nnnn

Quality components, quality support

nnnn

Efficiency ratings of higher that 90 per cent

nnnn

stem from the mixed-flow type pumps used

nnnn

in Kamewa waterjets.

nnnn

Built-in bearings absorb the impeller thrust,

nnnn

thus facilitating the inlet duct structural

nnnn

dimensioning.

nnnn

Each shaft-line is adapted when it comes to

nnnn

whirling, dimensions and weight.

nnnn

Minimal and simple cable installation

nnnn

is achieved through a new, computerized

nnnn

databus-based system for steering and

nnnn

reversing control, which can be used for

nnnn

both manual and joystick manoeuvring.

nnnn

Number and placement of stations can

nnnn

be customised. The system provides

nnnn

redundancy and real time control with a

nnnn

very high level of security.

nnnn

Stainless steel components provide long life

nnnn

and reliable service. Every waterjet size can

nnnn

also be supplied as a booster.

nnnn

The sale is just the beginning of a reliable

nnnn

partnership. Where ever you are in the

nnnn

world, Rolls-Royce provides a high level of

nnnn

service and support, including custom

nnnn

tailored service agreements designed to

nnnn

meet your individual needs.

nnnn

Optimised power for reduced fuel

nnnn

consumption

nnnn

The Kamewa waterjets can be individually

nnnn

optimized for every installation, providing

nnnn

reduced fuel consumption.

nnnn

Nozzle diameter and impeller pitch are

nnnn

matched to suit the operation condition as

nnnn

well as matched to gearbox and engine, in

nnnn

ordertoabsorbfull power. And.asmanyas 10

nnnn

shapes of the waterjet inlet are used to avoid

nnnn

flow separation and cavitation problems.

nnnn

Rolls-Royce utilises our own proprietary,

nnnn

computerised design program, which

nnnn

contains the latest waterjet technology, as

nnnn

well as actual results from earlier waterjet

nnnn

installations.

nnnn

With the aid of this program, individua

nnnn

influences and the combined effect of

nnnn

all parameters will be studied to find the

nnnn

solution that provides the best fuel economy

nnnn

for your installation.
