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

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.

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.

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.

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:

Fleible machinery arrangement

Modularised design

Simpler vessel machinery installation

Simpler hull form and structure

Reduced installation time and cost

Fewer components

Reduces shipyard/sub-suppliercoordination

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.

Steering starboard

Typical applications:S-series

Suitable for high speed vessels

such as:

passenger/car ferries

high speed naval and coastguard

vessels

yachts

A-series

Suitable for:

smaller passenger ferries

rescue boats

smaller high speed naval craft

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.

Waterjets

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.

Higher performanceat a lower cost

U P G R A D I N G

Our upgrading solutions can give your

ship a new lease of life with improved

fuel economy, reduced noise and vibrations and

increased speed and manoeuvrability.

Upgrading replacement components

can make dividends in vessel performance

and fuel savings.

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.
