At the leading edge ofpropulsion technology
Propellers/
reductiongears
Unlike other propulsor suppliers, Rolls-Royce
has its own marine propulsion laboratory
in Kristinehamn, Sweden, equipped with
two cavitation tunnels. One conventional
closed recirculating cavitation tunnel is used
for testing propellers, waterjet pumps and
thrusters in "open water", i.e. in homogenous
inflow. This tunnel offers a 2.5 m long, 800
by 800mm test section with water velocities
up to 11 m/s. The test object is driven by an
upstream drive shaft for tests of propulsors
under ideal inflow conditions.
As one of the few free-surface type tunnels
in existence, the second tunnel is used for
testing high speed propellers operating in
partially or fully submerged conditions, in
parallel or oblique flow. Propellers are tested
in behind condition (behind a hull dummy),
and waterjets are tested together with inlet
and steering and reversing unit as a complete
system. This cavitation tunnel offers a 4 m
long, 800 by 800 mm test section with water
velocities up to 12 m/s and possibility for a
free water surface in and downstream of the
test section.
Since the laboratory first opened in 1942,
about 1.400 models of propellers and waterjet
pumps have been tested.
In the quest for optimum propulsion efficiency,
with minimum noise and vibration, Rolls-Royce
engineers employ advanced theories and
calculation methods. During the last 15 years,
the viscous CFD has become an important tool
in the hydrodynamic research work. Simulation
of a complete ship hull and propulsion unit is
realizable today. Main methods can be divided
into transient (time dependent) and steady
state simulations. Generally, a non-transient
simulation is fast an accurate, but some
simulation needs to be solved transient, such
as a rotating propeller or waterjet operating in
its environment (wake field).
The strength of the Hydrodynamic Research
Centre (RRHRC) is to combine the advantages
of both the experimental and computational
fluid dynamic methods when developing
new products.
All propulsion products are delivered with remote
control systems. The electronic control systems are
undergoing continuous improvements to meet all
technical and ergonomical demands.
Decades of designing and producing propellers and thrusters, the use of sophisticated software and having our
own propulsion laboratory, is what enables us to develop the most efficient propulsion systems possible.

Technical data reduction gearboxes
Rolls-Royce reduction gearboxes
The reduction gearbox is a freestanding
gearbox intended for integrated
propulsion systems. It is designed as a
combined speed reduction unit with
common hydraulic system for gear
and propeller. The gear has a built-in
hydraulically operated clutch and is
provided with seating brackets for bolting
to the ships foundation. The input shaft
is provided for mounting of the flexible
coupling, and the output shaft with a
cylindrical shaft or flange.
The hollow bored propeller shaft carries
the oil tube.
The reduction gearboxes are normally
equipped with one-step reductions
from 1.5:1 to 6.3.
Rolls-Roycereduction gears
The thrust bearing is of the tilting pad type,
absorbing the propeller thrust in both ahead and
astern direction.

The Rolls-Royce high efficiency propulsion
and manoeuvring system, Promas,
integrates the propeller, a hub cap, a rudder
bulb and the rudder itself into a hydro-
dynamic efficient entity.
A tapered hubcap fitted to the hub of the
propeller leads the water flow on to a bulb
which forms part of the spade rudder.
The rudder has a twisted leading edge,
optimised for the flow from the propeller,
which converts into additional forward
thrust some of the swirl energy in the
slipstream that is normally lost.
The result is an increase in propulsive
efficiency of about 6 to 8% depending
on application, leading to reduced fuel
consumption and emissions. Large steering
forces can also be developed.
Promas has been developed using CFD(computational fluid dynamics), and the
results are verified by testing in the
cavitation tunnel at the Rolls-Royce
Hydrodynamic Research Centre and large
scale model testing with relevant hulls.
Available with CP and FP propeller.

The rudder bulb is close to the propeller hub, but not
attached to it. The nose of the bulb is curved, and
gives good control of water flow from propeller to
rudder even at large steering angles.

Rolls-Roycefixed pitch propellers
Rolls-Royce has many years of experience
in the design of fixed pitch propellers. In the
US we have our own foundry capable ofproducing fixed pitch propellers up to 10m
diameter in a variety of materials, to the
exacting tolerances required for modern
naval platforms. The characteristics of the
Bird-Johnson and Kamewa range of FP
propellers provide good fuel economy,
low vibration/noise levels and no harmful
cavitation. They are usually individually
designed for the specific vessel, to deliver
the optimum in propeller efficiency.
The Rolls-Royce SKF propeller sleeveThis propeller sleeve is a unique concept
that simplifies propeller removal and
mounting, provides full inter-changeability
between operating propeller and spare
propeller, and reduces the need for a spare
propeller shaft. It offers considerable cost
savings in terms of downtime, maintenance
and repairs. The SKF propeller sleeve also
generates major savings by speeding up
the installation process, eliminating match
marking or gauges. The FPP is designed
with either a taper shaft or SKF sleeve.
Rolls-Royce offers a complete FPP

Rolls-Royce adjustablebolted propellers
Propellers/
reductiongears
Typicalapplications:
cruise vessels
tankers
cargo/container vessels
various types of naval vessels
The adjustable bolted propeller
allows the most efficient blade
matching for optimum efficiency,
while simplifying the installation
process. The Kamewa range of ABP
is based on a hollow hub with
blades bolted to it from the inside.
A unique feature is the method of
bolting the blades to the hub using
simple hand tools.
In comparison to conventional monobloc
fied pitch propellers the ABP has
higher quality blade machining and
educed overall weight, which give easiershipment, handling and mounting. The
slotted holes on the hub allow the blade
pitch angle to be conveniently adjusted
at commissioning, or in service to
compensate for long-term variations in
hull resistance. Individual blades can be
replaced without drydocking, and only
spare blades have to be stocked rather
than a complete monobloc propeller.
Key features:
Spare propeller not
needed, thus shortpay-off compared to FPP
Slotted holes on the hub allow
stepless blade pitch angle adjustment
Stainless steel or NiAl-bronze blades
4, 5 or 6 blades available
Simpler, less costly installation at the
shipyard. Match marking not needed
Smaller, lighter components mean lower
costs for shipment, storage and handling
Individual blades can be
replaced if damaged Easy underwater installation and
replacement of blades
Hollow hub reduces total weight and
extends bearing life
Higher accuracy than a monobloc
propeller since individual parts are
machined more efficiently
No limitation in size or weight
The ABP offers fast and simple installation comparedto a monobloc unit.

Rolls-Royce is one of the worlds leading
suppliers of azimuth thrusters. The basic
idea behind an azimuth thruster is that
the propeller can be rotated 360 degrees
around the vertical axis, providing
omni-directional thrust. The Rolls-Royce
range of azimuth thrusters therefore offer
superior manoeuvrability. The simple
and robust construction provides high
operational reliability along with easy
maintenance, which result in a best
possible total economy.
The flexibility in design makes the
azimuth thrusters ideal to a wide range
of vessels. The low noise and vibrationlevels further enhance the area of use.
The Rolls-Royce thrusters can be delivered
for diesel or electric drive. The units are
available as open or ducted with fixed or
controllable pitch, or with contra-rotating
propellers. The azimuthing thrusters are
delivered with remote control systems.

Arctic operations
Rolls-Royce has a long history of delivering
azimuth thrusters for vessels operating in
icy conditions. These vessels range from
tugs and road ferries to icebreakers, withclassifications from Baltic ice classes to high
Arctic icebreaker ice classifications.
The applications require project specific
tailoring for the best possible azimuth
thruster solution.

The Rolls-Royce azimuthing contra-
rotating propeller, type Contaz, is the
worlds first thruster system designed and
built especially for merchant vessels. It
combines the benefits of contra-rotating
propellers with steerable thrusters. The
latest bearing, gear and shaft technology
are the keys to the Contaz refined and
developed through decades.
The Contaz also represents a new way
of designing and building ships, and to
arrange its power and auxiliary systems
for maximum economy, utilisation and
comfort. Every unit is specifically designed
and built for the particular ship it is goingto serve.
The overall benefits are better outline
arrangement, better propulsion efficiency,
better fuel economy, better coursekeeping
stability and reduced vibration and noise.

The Rolls-Royce azimuthing pulling
propeller, type Azipull, is a low drag, high
efficient pulling thruster. It combines the
advantage of the pulling propeller with
the flexibility of using almost any type
of drive to suit the customers specific
requirement. The Azipull is designed
for continuous service speed up to
24 knots, while maintaining excellent
manoeuvrability. High hydrodynamic
efficiency, fuel efficiency, course stability,
low noise and vibration levels are other
key characteristics of the Azipull.
Internally, it has a purely mechanical drive
system based on well-proven technologyusing bevel gears at the top and bottom
of the leg. Power is fed to the unit
through a horizontal input shaft within
the hull, and the unit incorporates its own
steering motors for azimuthing.
The Azipull combines the advantages
of an azimuthing thruster offering high
manoeuvrability, and low drag, high
efficient propulsor enabling high speeds.
The flexibility of the unit is also enhanced
by the fact that it is available in both CPand FP versions. The Azipull is delivered
with remote control systems.

The range of Rolls-Royce underwater
mountable thrusters are designed for easy
underwater mounting and dismantling without
dry-docking the application. This is of utmost
importance to large vessels and semi-sub oil
drilling rigs.
There are two alternative ways to connect the
lifting wires: Connecting inside the ship to the
thruster flange (see picture below) or externally
to the lifting lugs on the thruster flange (See
picture in the middle). The former is typical
on the drill ships and the latter on the Semi
Submersibles.
All necessary plugs, blinds and domes are
supplied with the thruster for underwater(de)mounting.

This thruster swings up into a housing in
the hull when not in use. It can quickly
be swung down about a horizontal axis
into the operating position. In operation,
it functions as an azimuth thruster and is
designed to develop maximum bollard
pull in the manoeuvring condition,
or to provide positioning power for
station keeping. The thruster has the
added safety benefit of functioning as
a get you home drive. A high thrust
is developed in relation to input power,
and this thrust can be vectored in any
desired direction.
In the stowed position the thruster doesnot protrude below the vessels keel/
baseline, an important consideration
for shallow water operations. Additional
azimuth thrusters are often located at the
lowest possible position in the hull due
to space envelope restrictions, especially
for equipment mounted at the bow, and
thrusters need to be retracted into the
hull when not in use.
Key features:

Azimuthing
thrusters
Rolls-Royce combinedazimuth/side thrusters
The Rolls-Royce combined azimuth/
side thruster is stored in the ships
hull by rotating the complete unit 90
degrees around the horizontal axis.
In the retracted position, the thruster
can be operated as a side force
thruster. The upper part of the thruster
is hinged, enabling the thruster to
be lowered through an arc into its
azimuthing position or retracted into a
recess where it lies horizontally in the
hull.
The Rolls-Royce thruster is designed as
a nozzle propeller in lowered as well
as retracted position. This means lownoise and higher thrust compared
with a traditional tunnel thruster.
The combi thruster version is
comprised of an equivalent standard
swing-up unit installed in a specially
designed hull module.
When in swing-up position (retracted)
the steering gear may be rotated so
that the propeller unit is used as a
transverse thruster.
Speed of response in terms of
changing thrust direction is similar to
conventional thrusters. The steering
unit can be rotated through 180 in
some 10 seconds. The combi thruster is
delivered with remote control system.

The range of Rolls-Royce retractable
thruster has the same main components
as our other azimuthing thrusters.
The retractable thrusters provide fast
hydraulic lifting and lowering of the
unit. UL thruster type is designed for
horizontal drive with automatic drive
shaft disconnecting system and ULE type
is designed for vertical drive.
The mounting is a "bolt-in" top mounted
type. The thruster is lowered into the
hull casing, bolted to the casing counter
flange and aligned. The lower end of
the lifting cylinder and the top of the
upper guide rails are connected firmly bybrackets to the ship's construction.

The Rolls-Royce electrical pod, type
Mermaid, propulsion system offers flexibility
in machinery and vessel arrangement, and
gives improved efficiency and excellent
manoeuvrability.
The outboard unit is 360 degrees rotatable
for manoeuvring purposes. In transit the
steering is optimised to achieve optimal
comfort and performance. The main
component in the underwater unit is
the electric motor, either a synchronous
type with brushless excitation or with an
induction motor. In both cases, the stator is
shrink fitted in the pod housing to optimise
hydrodynamics and cooling. The rotor ismounted directly on the propeller shaft
which is supported by state-of-the-art roller
bearings on both sides. It is also equipped
with a shaft brake, locking device and
equipment to slowly turn the shaft in order
to assist when undertaking maintenance
work.
The propeller is a fixed pitch high skew
type, designed for low noise and low
vibration. It can be delivered either as a
monobloc or with separately bolted blades,
with the benefit that they can be changed
individually in case of damage. All seals
against seawater are of environmentally
friendly type, i.e. seal failure will prevent any
oil spill into water.
Owner/Operator benefits:
Increased cargo capacity or reduced
vessel size
Increased propulsion system efficiency
Reduced total installed power generation
Reduced total fuel consumption and
exhaust emissions
High capability remote controlled breakand locking unit
High manoeuvrability
Reduced noise and vibration levels
Environmentally friendly seal systems
Optional: Underwater mounting
Shipyard and construction benefits:

Rolls-Roycewaterjets
Superior performanceand manoeuvrability
The waterjet has many advantages over
a propeller. The Rolls-Royce range of wa-
terjets have a very high pump efficiency.
This provides higher speeds with the
same power, or, substantially lower fuel
consumption at a constant speed and lower
power.
At constant rpm, Rolls-Royce waterjets
absorb approximately the same power
regardless of the ships speed. The engine
cannot be overloaded, which means fewer
breakdowns and an increased life cycle.
Waterjets produce less vibration and noise
than propellers. At speeds over 20 knots, the
vibration and noise can be reduced by more
than 50 percent. In addition, with two or
more waterjets, manoeuvrability is excellent,
making quick dockings with perfect
precision standard every time.
The ability to accelerate, reverse, stop and steer
is excellent compared to propeller propulsion.

The impellers task is to pressurise the water. The
reaction force that is created when the water leaves
the pump is utilised to propel the ship.
The impellers rotation is never reversed, so no
reversible gearbox is needed for this action.

Rolls-Roycemixed-flow waterjets,S-and A-series
Waterjets S-series
The Kamewa S-series of waterjets is developed
for the most demanding applications. The
Kamewa waterjet S- and A-series are equippedwith the market's highest performance wa-
terjet pump of mixed-flow type, developed at
our own Rolls-Royce hydrodynamic research
centre in Sweden to meet the market demands
on efficiency and environmental aspects. To
facilitate the hydrodynamic performance of the
pump, the built-in bearings keep the impeller
in correct position and provide control of the
important tip-clearance. The outboard bearing
position also simplifies the overall load distri-
bution in the aftship and leads to efficient use of
the inlet duct as load carrying structure.
The Kamewa S-series have five impeller blade
designs, eight pump outlet nozzles and at least
10 variations of inlet duct designs are utilised to
optimise the unit for each application. Minimal
and simple cable installation is achieved
through computerised databus-based system
for steering and reversing control, which can be
used for both manual and joystick manoeuvring.
The system provides redundancy and real-time
control with a very high level of security.
Key features S-series:

Waterjets FF-series
The Kamewa FF-series are manufactured
from strong, corrosion resistant materials.
The impeller shaft and steering/reversing
rods are made of stainless steel, remaining
components are made of light aluminium.
The interior surface of the impeller housing
is lined with a special rubber-like material
to minimise wear and noise. The pump is a
single-stage axial flow design, providing a
high volume flow with good pulling thrust
at lower speeds. Usually, the Kamewa FF-
series jets do not require reduction gears.
All Kamewa FF-series waterjets can be
supplied as booster unit without steering
and reversing gear.
The Kamewa FF-series waterjets have in
several comparison tests proved to have
5% higher thrust force than the competing
waterjets. The Kamewa FF-series can be
installed on both displacement and planing
craft as single, twin, triple or quadruple
systems.

Once a product is in service, it is expected
to last 25 years or more. During that time,there will be tremendous changes in the
technology available.
To continuously improve your vessels
performance, we provide a variety of
upgrading solutions. The advances in
propeller design can help older vessels.
I.e. replacing old blades with new ones
on an existing CP hub can pay dividends
in saving fuel. Modules are often
developed so that when an old unit is
overhauled, a new module is substituted
for worn components of the originaldesign. This upgrades the performance
of the product as well as restoring it to
health.
With Rolls-Royce as your service partner,
our experienced engineers upgrade
old applications or purpose-fit new
equipment to your vessel. This means
that you can meet changing markets
without having to carry out expensive
rebuilds in many cases.

Operational availability must be maintained today in the most
cost-effective way. Variable market conditions and increasing
competition should not undermine safe ship operation.Therefore, we work closely with our customers to support their
fleets, ensuring they are operating safely and at maximum
efficiency, with the goal of virtually eliminating unscheduled
downtime.
A comprehensive menu of service solutions
We are proud of the performance of our systems, and are
keen to ensure that they continue to operate at their peak
throughout their lifetime. Our services now range from
conventional product support, with no impact on ship
availability, through to a range of equipment and systems
support packages with levels of vessel performance andavailability agreed, normally within a long-term risk and reward
sharing partnership called MarineCare.
Single point of contact
As we have progressively increased the breadth of our product
range, we have continued investing heavily in the facilities
and the talent needed to support them. As multiproduct
installations are becoming standard on a growing number of
vessels, customers benefit from a single point of contact for
support, which is usually the nearest Rolls-Royce regional centre
to the vessels location.
Reducing through life costs
Reducing operating costs and maximising availability is our
objective. This has led us to work closer with a number ofour customers in maintenance planning and recommending
spares holding. By being involved from the start we have the
opportunity to focus on the activities that make a difference,
acquiring and pre-positioning service or exchange parts to
ensure a smoother overhaul process, saving time spent in dock.
Committed to meeting different needs
Above all, at the centre of our support philosophy, is recognition
that all customers have different and often unique require-
ments, based on their fleet operations. Whatever the mix
of requirements, Rolls-Royce is committed to meeting or
exceeding them.
Product training
At Rolls-Royce we believe regular training ensures that you will
get the most out of a vessels equipment and systems and also
ensures that they are operated and maintained efficiently and
safely.
Eperienced and informed people are a key asset.
As technology advances, so must the competence levels of
operators and service personnel. We therefore offer a range of
tailored training courses and programmes in state-of-the-art
facilities equipped with the latest simulators and training aids.
Global service and support
Our support teams, located world wide, are committed to helping you
manage the vital balance between operational availability and cost. Wherever
your vessel is located, Rolls-Royce support is close at hand.
