Dear Customers,Dear Readers,

Technological heroes cross our paths on countless

occasions every day – even if we do not always see

them. These heroes are the result of technological

developments that guarantee progress and ensure our

future. Technological development has always been

part of our evolution – combined with a clear mission:

it must be beneficial to mankind. With innovative

technologies, Voith ensures the reliability of technical

systems all around the globe. This includes the devel-

opment of new technologies and also the consistent

further improvement of existing methods and systems –

for road, rail and industrial applications, as well as for

ship propulsion systems.

In this issue we are introducing a new feature presenting

technologies that are used in a wide variety of applica-

tions world wide. We are starting with the SteamTrac.

A system that utilizes waste heat and makes it available

as drive power. It allows a reduction in fuel consump-

tion and CO2 emissions in rail vehicles, ships, power

stations and trucks.

Future-oriented mobility policies are a central theme at

the 59th UITP World Congress, which is held in Dubai

in April. Dubai has plans for ambitious transport projects

with the defined goal “Smooth and Safe Transport for

All.” Voith Turbo recognized the market potential of the

emirate in the early nineties and is now successfully

represented there with all its business divisions.

Voith is particularly involved in the expansion of public

transport systems – from metros and new railway lines

to the modernization of bus networks.

In our Marine section you can read about a true supply

giant, a floating 600-bed hotel. With a capacity like

this it is possible to accomodate entire platform crews.

This platform supply vessel is driven by Voith Schneider

Propellers. On our Industry pages we introduce a

new fluid coupling. More powerful than ever before,

this mining coupling makes coal extraction even more

efficient – it is about to enter service at one of the

leading mining companies in Chinas.

As always, I hope that you will enjoy this issue of

News!

Yours sincerely,

Peter Edelmann

Everyday HeroesRunning water, energy supply or reliable public transport – everyday services that are taken for granted by millions of people. With innovative technologies, Voithensures the reliability of technical systems that have become a conveniencein the daily life of many people. This is what simultaneously happens when it’s 13:00 hours in Germany.

04:00 hours Shortly before sunrise,

the sky above Los Angeles Harbor is

slowly turning red. The night was quiet

for the crew of the fire department,

which patrols the harbor basin regularly

on the L. A. Fireboat. Safety has top

priority in the two harbors Los Angeles

and Long Beach, the largest goods terminals at the

American west coast. 16 400 people work here.

With a freight handling capacity of 170 million tons

(2010), the harbors hold place ten among the

world’s busiest ports.

Safety in the Harbor

The L. A. Fireboat is optimally equipped for an emergency in the harbor. There is no comparable fireboat with equally efficientfire extinguishing pumps or a similar degree of maneuverabilityin a confined space when disaster strikes. Fitted with ten watercanons, the L. A. Fireboat is capable of directing 10 300 cubicmeters of foam-water mixture onto the source of the fire andmaneuver flexibly in the harbor basin. This maneuverability isprovided by the Voith Schneider Propeller. It also allows usingthe main motors of the boat as drives for the water pumps. With this unique marine drive, thrust can be generated in alldirections and at any magnitude – smoothly, fast and withhigh precision.

07:00 hours The early morning rush hour

chaos in the Columbian capital Bogotá

is about to begin. 5.5 million people

commute from the suburbs to their work-

places in the city. Most of them travel

on one of the 25 000 buses or 50 000

taxis. Every day, South America’s

fastest growing metropolis experiences the same sce-

nario. An exception is the traffic concept TransMilenio.

Since 2000 the BRT (Bus Rapid Transit) system brings

some order to the chaos that is otherwise typical for

Latin American metropolises. As a result, the quality of

life of the commuters is significantly improved. Since

the introduction of the system, 1.4 million people use

one of the 1100 articulated buses of the TransMilenio

lines every day.

The BRT system excels by very short intervals between busesand high transport capacities, flexibility and low infrastructurecosts for the bus network. A special feature is the dedicatedand, above all, completely separate bus lane, allowing the busesto drive through the traffic without any obstacles. As a result,the daily commute for the passengers is reduced by morethan 30 percent. No wonder that Bogotá has become theworldwide role model for BRT systems. Over 80 percent ofthe vehicles are fitted with Voith DIWA transmissions.

In conditions such as these, the DIWA automatic transmission,which was developed specifically for city buses, offers genuinefuel savings for operators and higher comfort for drivers and passengers. The Voith Retarder that is integrated in theDIWA.5 provides a plus in safety. This wear-free continuousbrake keeps the temperature of the service brake low, makingit fully functionable in an emergency. The retarder is suitableas a continuous braking system, be it on long and demandingserpentine routes, holiday and long-distance journeys or inurban stop and go traffic.

08:00 hours The loud crash quickly

fades away in the desert. What

remains are meter-high clouds of dust

and falling rocks. An everyday occur-

rence for the workers in the Quebrada

Blanca copper mine. The rocks in the

area contain large amounts of copper,

which is being extracted in a fairly complex process.

Our everyday life would be unthinkable without the soft

and pliable heavy metal. It would be difficult to find a

cell phone or other high-tech electronics without copper

components. The material is used for cables, tubes,

electronic devices or cooling systems. Copper tubes

are heat, cold and pressure-resistant. It would be

impossible to build electric motors without copper.

The work in copper mines, such as the one in Chile, is there-fore all the more important. Every hour, 1 300 tons ofrock are passing through the mining and production process.Conveyor belts measuring up to 1.6 kilometers in length and fitted with Voith fluid couplings ensure the trouble-freetransport of the copper ore. The Voith couplings absorb joltsand guide the conveyor smoothly from start-up to normaloperation.

Nothing Works Without Copper

09:00 hours Vast, teeming crowds

underground, the picture is always the

same: day after day, three million

people use the metro in the Brazilian

metropolis São Paulo. The infrastruc-

ture and the network are well devel-

oped, making it possible for most of the

trains to run at 100-second intervals. After Paris

and Moscow, the São Paulo metro is therefore one of

the world’s leading underground systems. The net-

work of South America’s largest metro spans nearly

70 kilometers, and the passengers rely on safe trans-

fers to one of the over 60 underground stations.

In order to make traveling more comfortable for the passengers, Metro São Paulo has been modernized in 2010with semi-permanent and automatic couplers from VoithTurbo Scharfenberg. The couplers improve the safety and offer impact protection. Voith Turbo has developed a completely new Scharfenberg coupler with energy absorption elements. The new couplers, designed for animpact of 800 kilonewton (approx. 82 tons), are gas-hydraulic dampers and increase the passive safety of thepassengers.

12:00 hours Supply vessels such as the

Edda Fram sail regularly from Aberdeen

Port, in order to deliver provisions

and new working materials to platform

crews. The trip to one of the altogether

16 Brent platforms across the Shell

oilfields in the North Sea takes about

20 hours. The men on the Brent Alpha north of the

Shetland Isles do not have an easy job. Every day they

ensure that the valuable raw materials oil and gas are

safely extracted and transported to the large refineries

via pipelines. It is estimated that, until 2020, the daily

oil production in the North Sea will amount to two million

barrels. Life on one of the oil platforms, which measure

approximately 8 000 square meters, is marked by long

shifts and rough environmental conditions.

Platform supply vessels set off whenever something has to be delivered to the oil platforms, however rough the weather.In a heavy storm, the waves can easily be ten meters high. In order to cope with such conditions, the ships are fitted

13:00 hours This is the time when

numerous taps are turned on all around

the globe. And as always, the pipes

deliver fresh water to millions of house -

holds. In Algeria, one of the most arid

countries in the Mediterranean, this

does not happen so automatically.

80 percent of the state territory in the Sahara is extremely

dry, with only 16 days of rain per year. In order to

ensure regular water supplies to the population, desali-

nated and processed water has to be pumped to those

regions, where drinking water is otherwise not available.

One of the most important supply lines is the 740-kilometerwater pipeline from In Salah to Tamanrasset. Every hour,millions of liters of water flow through the two lines with adiameter of 800 millimeters. The six pumping stations need18 pump units plus motors. Voith Turbo delivered the geartechnology for all pump units. The Voith helical gears for

transmitting high outputs have been designed and configuredspecifically for the requirements of this project in Algeria.

In some regions in Algeria, where drinking water is not available, specially processed desalinated waterhas to be pumped to the population.


13:00 hours The signal shows green.

The high-speed train Velaro E of

the Spanish state railway company

RENFE slowly rolls out of Madrid’s

main station. When fully booked, it

can accommodate 405 passengers

in three classes. And the train is often

fully booked: since entering service

in 2008, a total of 2.3 million passengers utilized the

high-speed route between Madrid and Barcelona.

This popularity is mainly due to the high comfort and

the time savings offered by the train – with a top

speed of 350 km/h, the Velaro shortens the journey

time by more than two and a half hours.

Passengers therefore only need two hours and

38 minutes for the 621-kilometer trip.

An essential contribution to this high-speed performance ismade by a specially developed final drive from Voith Turbo.Every train features 16 drives that are installed directly beneaththe passenger compartments. The final drives were designedto ensure extremely low unit weights (only 311 kilogram) andlow nose emissions. The Velaro is a platform and can there-fore be modified to the special requirements of customers invarious countries. Voith final drives and Scharfenberg couplerscan thus also be found in Chinese high-speed trains (Velaro CN),as well as in the German ICE. They make rail traffic reliableand allow fast connections between large cities.

13:00 hours When the new season

starts, fashion designers have to

make sure that their new collections

get to the shops as quickly as possible.

Some of these deliveries are

carried out by rail, for example from

Magdeburg. Several times per year,

tons of leather goods, textiles and clothes are loaded

into freight cars that are pulled by a powerful locomo-

tive. With 79 million tons, semi-finished and finished

products occupy the largest part of the freight trans-

ported by rail (in total 312 million tons). The Gravita

locomotive, which was approved in June 2010, also

performs this kind of service.

The Gravita locomotive family from Voith has been developedmainly for regional distribution traffic and local shuntingduties. With a weight of 80 tons, an output of 1360 HP anda maximum speed of 100 kilometers per hour, the Gravita is suitable for both mainline and shunting service.

14:00 hours 15 minutes ago, the ferry

MIF SUHULET left the European

terminal Serkeci. After successfully

crossing the Bosporus, it will soon

land in Harem on the Asian side.

A short but very important crossing

for people who want to get from one

to the other side of the Turkish metro polis Istanbul.

Commuter traffic on the sea strait is continuously

increasing. This is why the municipal ferry operator

in Istanbul decided four years ago to put four

double-ended ferries in service. With the new ferries,

10 000 vehicles can be transported.

The Bosporus is notorious for dangerous currents, rapidlychanging winds and huge amounts of traffic caused by tankersand container ships. This is why the ferry operator decided infavor of ferries that are not only highly reliable, but also allowsafe berthing and casting off. In the four double-ended ferries,this is ensured by a total of eight Voith Schneider Propellers.

17:30 hours Rush hour in Mumbai, India’s

financial center. At this time of day,

commuters are often stuck in traffic, and

the exhaust and noise pollution in the

city with its nearly 14 million inhabitants

is correspondingly severe. As the popu-

lation is set to grow further over the next

few years, the city has launched a new kind of urban

transport: the monorail. With the monorail, which

entered service only recently, 300 000 passengers

can be moved every day. All destinations in the metro -

polis Mumbai can be reached within one hour. With

the electric monorail system, India also clearly opts in

favor of eco-friendly solutions: every day, monorails

save 25 percent energy and emit 2 000 tons less CO2.

For the first 15 trains on the route that covers 20 kilometers so far, Voith Turbo Scharfenberg has delivered 30 front endmodules. The trains of this first route section connect thesouth of Mumbai with the eastern suburbs (Jacob Circle –Wadala – Cembur). 18 Stops will be built along this line segment. The trains run at six to nine-minute intervals. A four-car train can move up to 600 passengers per trip.

15:00 hours The water for the afternoon

tea is boiling in the kettle. The kettle

stands on the bluish flame of a gas

range. It is taken for granted that natural

gas is available 24 hours a day for

lighting a flame. It is both a habit and

an expectation. But the path of the

raw material from the source to the consumer some-

where in Russia can be long. It is often located in an

area where not a single soul is to be found – for example

in north-west Siberia, beyond the Arctic circle, buried

underneath a vast snow desert or deep down on the

seabed. The main pipes of the extensive Russian

pipeline network cover over 185 000 kilometers.

In order to make sure that the gas arrives at the end of thepipeline, compressor stations have to be installed at regularintervals. Without them, the gas, when transported over longdistances, would lose pressure due to friction caused by thepipeline walls. At the stations, the gas is compressed, and then“sent” on to the next pipeline section. Compressor stationssuch as these operate with a Voith Vorecon. The variable-speedplanetary gear combines hydrodynamic control componentswith a superimposed gear.

The main pipes of the Russianpipeline network are 185 000kilometers long – enough to circle the earth 4.5 times.


20:00 hours In China, the electricity

consumption in private households

begins to rise dramatically. The power

to cover this demand is increasingly

generated by renewable sources – for

example wind or hydro power. The

highest percentage of electricity is still

won by coal-fired power stations, but the share of

renewable energies is growing. More and more wind

parks are emerging, especially in the windy northern

and western regions of the country.

More Electricity From Wind Energy

ShanghaiChina

Jiuquan in the Gansu Province, north of Beijing and a three-hour flight away. By the middle of 2011, it will be home to pilotwind power stations fitted with the Voith WinDrive as corecomponent in the driveline. The WinDrive stands out for excellentgrid feeding quality. Higher availability combined with reducedmaintenance requirements result in lower power generationcosts. Due to earlier capacity problems, the Chinese governmentnow invests in the development of its power grids – excellentpreconditions for further growth of China’s booming wind andhydro power industry. Alongside other projects, Voith Hydroalso participates in the Three Gorges Dam.

22:00 hours Shortly before sundown, a

train sets off in Australia offering fantas-

tic views of a wide variety of sceneries.

The “Sunlander” runs from Brisbane to

Cairns, alongside pineapple plantations

and sugar cane fields along the east

coast, through gold mining towns, unspoilt

nature reserves and primeval rain forests.

This route makes particularly high demands on the train

technology. The Sunlander, complete with sleeping

coaches and restaurant cars, must technically comply

with the moderate climate in the south, as well as the

tropical temperatures in the north.

IN FOCUS EVERYDAY TECHNOLOGY | NEWS FROM THE VOITH GROUP

Europe’s Green Battery

The energy requirements of a society

can fluctuate quite strongly. There

can be periods of peak demand,

especially during live TV broadcasts

of huge, popular sports events.

Pumped storage power plants are

the ideal back-up to ensure that the

grid does not collapse during such

peak times. These plants recognize

high-demand periods and feed

large volumes of energy into the

grid within seconds. This is made

possible by reservoirs that are able

to store electricity like huge batter-

ies. During load peaks, the water

from the upper reservoir is directed

into a lower reservoir and drives

turbines and generators. If there is

an energy surplus in the grid, the

water is pumped back into the

upper reservoir. Turbines for such

power stations, which can be found

all around the globe, often originate

from Voith Hydro. The most modern

plants in the world are Goldisthal

(Thuringia, Germany) and Kops werk II

(Austria). At the moment, Voith Hydro

is producing a machine set for

Rodundwerk II (Austria), which is to

re-enter service at the end of 2011

with an output of 295 megawatt.

Voith Ensures Energy Supplies

In many regions around the world,

energy power generation by wind

power is an everyday appearance.

Relevant prognoses claim that

by 2020, there will be wind power

plants with an output of 1 900 000

megawatt all over the world.

Last year, the output was still

203 500 megawatt.

FKi Engineering Ltd., UK, has

signed a comprehensive service

contract with Voith Industrial Services

for a wind park with 46 MW in

Vienna. In this way, the London-

based operator is making sure that

the plant is always available. The

maintenance agreement comprises

the immediate elimination of failures,

as well as the remote monitoring of

the power station. The performance

of the wind park is audited in week-

ly and monthly reports. Two service

teams are permanently based in

the wind park. Already in the first

few months, the availability of the

park could be increased from 85

to 98 percent.

Prof. Kreibich, do you expect to see

completely new technologies, or

rather an improvement of existing

systems?

I can see both. When it comes to

further developments I anticipate

enormous rationalization measures

regarding working processes and

even more so in terms of resource

utilization. Just look at our daily

shopping in the supermarket. The

goods are displayed on shelves,

put in a shopping trolley that runs

through a reading sensor, which

displays the total bill. Cashiers are

no longer required.

In medicine, things are even more

interesting through the use of chip

sensors. These sensors can access

organs far more efficiently, diagnoses

can be made much quicker and

with higher precision, and medica-

tion can be determined more

accurately. The result is fully individ-

ualized medicine. And there will

also be new and individual techno -

logies for households and mobility.

A field in which we urgently need

progress is energy storage technolo-

gy. There are now new developments

and not enough research on how

to store energy and heat effectively

and affordably. After more than

100 years, pumped storage power

Technical development is part of our evolution. All over the world, scientists are working on implementing their knowledge into new technologies. The question is: which technologies are beneficial to humankind – in the sense of sustainable technologies? Prof. Rolf Kreibich explains, why the challenge of new technologies lies in energy and resource efficiency.

Prof. Dr. Rolf Kreibich of the IZT Institute for Futures Studies and TechnologyAssessment in Berlin

The 21st Century Must Be an Era of Resource Efficiency



plants are still regarded as the best

storage technology for electricity.

And where can you see new areas

for technical development?

We will see new developments in

gene technology or in bionics. In

bionics, it is a matter of applying

systems found in nature to the world

of engineering. The goal is energy

and material efficiency. This is a

vast research field, which we have

approached too timidly for too

long. At least there are some new

approaches, for example regarding

ship contours that increasingly

emulate the shape of fish.

Another important area for innova-

tion are modern, ecological and

solar construction technologies.

I am thinking for example of a better

passive utilization of solar energy.

Solar-thermal systems or insulating

materials made from biomass with

only one tenth of the thickness of

conventional polystyrene panels.

They offer the same insulating prop-

erties, but are far more eco-friendly.

In your studies, you are asking

for increased efforts toward more

sustainable traffic and transport

technologies. Give us a few

examples.

Regarding public transport, I

think that high-speed trains are the

way of the future. They are a

genuine alternative to planes on

short and mid-range routes. Our

next efforts should concentrate

on making these trains even more

energy efficient and using even

fewer raw materials for their con-

struction – and this also applies

to the interior fittings.

More drastic changes are required

in the field of freight transport.

There should be a noticeable shift

to transport by rail and water. There

have been predictions that until 2025

road transport in Europe will grow

by another 60 – 65 percent. Sooner

or later the system will collapse.

Countries such as China or Brazil,

which still have an opportunity to

move more goods by water or by

rail, should jump at the chance.

You also count airships among eco-

friendly transport carriers – but they

run on well-known technologies …

… which does not automatically

make them bad. For me, “lighter

than air” technologies with balloons,

drones or airships are quite promis-

ing. Today, thousands of kilometers

of gas and oil pipelines are monitored

by helicopters. This is cost and ener-

gy intensive and causes enormous

noise emissions. Balloons, remote-

controlled and fitted with cameras,

can watch such networks eco-friend-

ly and nearly without any noise.

Or think of rescue operations during

natural disasters, when people

flee onto their roofs. Helicopters

cannot land there or might even blow

people into the floods. But airships

would be able to come to the res-

cue. In tourism, sightseeing flights

across cities and scenic areas could

also become more eco-compatible

with airships, saving on aviation fuel

and reducing noise emissions. Our

long-term goal should be to use

airships also for freight transports.

Several countries, among them

the USA and Canada, are already

working on this concept. Not partici-

pating in this idea means missing a

great opportunity.

Will our everyday life become even

more high-tech?

I am convinced it will. We can’t turn

the wheels back. It is, however,

important to keep an eye on these

development and always assess

and evaluate the consequences of

this technical progress: which tech-

nologies are really useful to man -

kind? I am thinking of sustainable

developments and an improvement

of living standards. We must focus

more on cycles, handle resources

more thoughtfully and efficiently

and understand technology as a

useful extension of our possibilities.

It is of course clear that there will

always be people who say “I don’t

have to use every new technology.”

To which degree a technical with-

drawal is possible in our modern

society, remains to be seen. People

who do not want to receive e-mails

and don’t use the Internet, are more

or less left behind and isolated.

At the same time we should always

accept lifestyles, which consciously

renounce one or the other technical

application.

It is hardly possible to talk about

everyday technology without

looking at future mobility. What do

you expect in this area?

We need to rethink as far as individ-

ual traffic is concerned. 70 percent

of all commuters do not really have

to use their car in order to get to

work. They would normally get there

equally fast by using other means

of transport. In the car sector, a lot

could be changed today, but the

industry is not willing to go ahead. In

cooperation with Greenpeace, our

institute developed a 2.8-liter car as

“Technology is the useful extension of our possibilities.”

Airships are eco-friendly means of trans-port, helping to reduce fuel consumptionand CO2 emissions.

forward to a combination of individ-

ual and public mobility. This also

applies to car sharing. In Germany,

there are currently 560 cars per

1 000 inhabitants, in the USA this

figure amounts to 780 cars, with

California holding a record of 1140

cars. In China, we have a mere

21 cars per 1 000 people, in India 11

and in Pakistan 7. Our earth could

simple not cope with a catch-up race

by these countries on the basis of

our current automotive technolo-

gies. This is why we have to rethink

consistently and go for sustainable

mobility and traffic technologies.

Could it be generally said that

technology has made the world a

better place?

Technology has certainly stirred up

a lot and shaped today’s industrial

societies. Yet people primarily expect

that technologies improve their

quality of life. To me, the most far-

reaching development is probably

the generation of electricity and its

universal utilization. Other milestones

worthy of this name are the develop-

ment of omnipresent water supplies

or raw material extraction. In gener-

al, it can be said: technology has

had a dramatic impact on mankind.

Over the last 100 years, our life

expectancy has increased by

38 years. Thanks to modern traffic

systems, mobility has been improved

by a factor of nearly 100. People

can travel wherever they want.

Today, a single employee generates

the same production value as

45 people 100 years ago.

Your prognosis for the 21st

century?

The 20th century was the age of

labor efficiency, the 21st century

must become the era of resource

efficiency, if we want to stay ahead

of the game. This also includes

people who use far too much heat,

electricity and raw materials in

their private households. Our efforts

should aim at utilizing technical

possibilities, particularly in the field

of resource protection. Then tech-

nology will be even more beneficial

for our quality of life. And industrial

companies have to learn that it is

indeed possible to make economic

and simultaneously ecological and

social profits, i. e. go for sustainable

production and marketing. Environ -

mental requirements have to be

incorporated into our economy. We

have a wealth of knowledge on

how to handle our life and our busi-

ness in an ecological and socially

compatible manner, which would

result in genuine sustainability. But

sadly, we rarely put this knowledge

into practice.

“We must consistently pursue sustainablemobility and transport technologies.”


Dubai continues to be the boomtown at the Persian Gulf. Even after the

economic crisis, there are numerous construction projects, the infrastruc-

ture is being expanded and the public transport network is constantly being

developed further. Voith Turbo recognized the immense market potential

of the emirate already in the early nineties and is meanwhile successfully

established there with all Group Divisions. Huub Hendrickx, Executive Vice

President of Voith Turbo in Middle East, reckons that the best opportuni-

ties lie in the market for drive components for buses and rail vehicles.

“Anybody who wants to do business

in Dubai has to be present in the

region,” this is how Huub Hendrickx

summarizes the situation. And he

also explains why Voith no longer

looks after its customers in this

emirate from Cyprus as in the years

before. Voith Turbo moved to the

neighboring emirate Sharjah as early

as 2003, and opened a subsidiary

with workshop, sales and accounts

departments in the free trade zone.

At the time, the main focus was

on drive components for industrial

plants, especially for the oil and

gas industry and also for energy

generation. In this field, Voith is

highly successful in Dubai, having

sold 3 000 units, among them fluid

couplings and Vorecons.

Expansion of the Bus Fleet

Since 2006, the citybuses rolling

on Dubai’s roads day after day

would be unthinkable without Voith.

In 2006, the booming region need-

ed new buses for the expansion of

its public transport system. Voith

received an order for the delivery

of DIWA transmissions for 660 vehi-

cles of Dubai’s Roads & Transport

Authority (RTA). This paved the

way for Voith to enter the emirate’s

market for road vehicles. At present,

1 650 new buses of RTA have Voith

DIWA transmissions, a market share

of 100 percent. “We also aim to

ensure that Voith provides the after

sales service for the majority of

the vehicles, once the transmissions

have been delivered,” says Huub

Hendrickx. Voith offers long-term

maintenance and service programs,

which keep the drive components

in optimum condition.

Metro Through the Desert

Public transport enjoys a high

profile in the Middle Eastern region.

And what’s more, Dubai strives to

establish itself as a sustainability

role model for countries such as

Saudi Arabia, Kuwait, Qatar, Bahrain

During the rush hour, metros run at 100-second-intervals.

or Oman. Urban planning projects

therefore not only allow for an

increasingly mobile society, but also

continuously work on the further

extension of rail transport. This is

reflected in new trams, but most of

all in Dubai’s metro. Two lines of

the metro, which runs right across

the desert, are already in service.

The metro system connects the city

center and offers links to important

outer stations. This relieves the

roads, which are already heavily

congested. The service intervals

are often very close: during the

rush hour, the waiting time between

trains is less than 100 seconds. All

RTA metro vehicles are fitted with

Scharfenberg couplers, which are

also serviced by Voith. The climatic

conditions, ranging from extreme

heat, sand storms to high salinity in

the air make enormous demands on

the couplers. It is expected that the

metro network is completed by 2012.

Special Vessels with VSP from Dubai Shipyard

In the meantime, Dubai has also

become an interesting market for

Voith Marine. The Dubai shipyard

Lamprell Energy currently builds

a Windcarrier with three Voith

Schneider Propellers. Wind carriers

are special vessels for installing

wind power stations on the high

seas. These jack-up vessels can

drive four columns or “jacks” to the

bottom of the ocean. These jacks

then lift the vessel and turn it into

a stable operating platform in the

water. Executive Vice President

Huub Hendrickx plans to expand

the marine business to Kuwait

and Qatar in future.



Mr. Hendrickx, road or rail vehicles,

industrial or marine applications –

Voith Turbo is successful with all its

Business Divisions in Dubai. What

is the reason?

Voith has been a reliable partner

for the OEMs and transport opera-

tors from day one. And we act

locally: in April, we are celebrating

the opening our new subsidiary in

the TechnoPark in Dubai – a nine

million square meter industrial park

in the desert. At the moment, only

about ten percent of this area are

covered by buildings; many investors

have backed off last year because

of the economic crisis. Voith Turbo

was one of the few companies to

put its plans into practice and start

with a new building on 12 000

square meters in 2009. This has

earned us a good reputation.

Tell us about the Voith premises in

the TechnoPark!

We have workshops for DIWA and

rail transmissions and a perform-

ance test stand with an output of

400 kW. It will be used for testing

overhauled components before

they are returned to the customers.

I think it can be said without

exaggeration that Voith Turbo

has the most modern and best-

equipped workshop in the entire

region. This has already been

highly acknowledged by our large

customers.

What are your key strategies in the

Middle East?

Apart from new orders and the

delivery of drive components we

aim for long-term maintenance con-

tracts. We are not here for quick

profits, we want to look after our

customers for years to come.

Voith Turbo in Dubai will be a sub-

sidiary, covering all business areas

and able to act competently and

fast in the region. For this purpose,

we are hiring qualified personnel,

especially for service and order

handling in the industrial business.

In the areas road and rail we do of

course provide service exchange

transmissions, and we have a

test stand and skilled personnel to

deal with the after sales market.

You keep mentioning Dubai’s high

market potential. How does this

manifest itself?

Huub Hendrickx On Voith Turbo in Middle East

Acting Fast and Competently in the Region

The high market potential derives

from the market region. With 19

million square kilometers, the Middle

East is almost twice as large as

Europe. The oil and gas fields of

Saudi Aramco or the gas fields in

Qatar offer a fantastic potential for

our industrial products. Both for

new plants and also for overhauls,

maintenance and retrofits. Due to

the permanent rise of mobility we

are involved in the expansion of

the public transport system. After

buses, trams and metro trains in

Dubai, it is now time to develop

the infrastructure in the prosperous

emirate Abu Dhabi. There is an

enormous need for trams, metros,

water taxis and buses. Voith is

already represented with DIWA

transmissions in 600 buses. I can

also see a huge potential in the

establishment of the rail network of

the Gulf Cooperation Council (GCC).

We are talking about an investment

of 130 billion Dollar over the next

10 to 15 years. And we want and

have to be part of it.

Huub Hendrickx has been looking after Voith Turbo Middle East as

Executive Vice President for the last five years. In an interview he talks

about the market potential of this region, strategic considerations

and the standing of Voith in Dubai.


TECHNOLOGY

Reducing fuel consumption effectively and simultaneously achieving higher energy levels – this is

not a contradiction. The SteamTrac system from Voith proves it. In rail vehicles, ships, thermal

power stations and soon also in trucks – the end result is always a 4 to 12 percent drop in fuel

consumption and CO2 emissions.

SteamTrac – for Applications in All Combustion Engines

Waste Heat is the Key Toward HigherOutputs and Lower Consumption

The operating principle is simple:

from the waste heat of combustion

engines, super-heated steam is

directed into the SteamTrac via heat

exchangers. The SteamTrac then

generates additional mechanical

energy, which is fed directly into

the driveline. Since March, a

SteamTrac has been operating in

a rail test vehicle. The single-car

diesel railcar type NE81 made

by Waggon Union Berlin in 1993

has been fitted with two 250-kW

diesel-hydraulic drive systems and

a Voith T211r turbo transmission.

According to Voith calculations, the

SteamTrac, which is connected to

one of the two engines, results in

fuel savings of 6 to 10 percent,

depending on the vehicle’s current

driving cycle.

Barge Needs 40 000 LitersLess Diesel

What is still in a trial phase for rail

vehicles, has already proven itself

26 1/2011 | Voith Turbo | News

In principle, SteamTracs can beinstalled in all diesel-driven railvehicles.

The SteamTrac also makes sense in thermalpower stations and biogas plants. The extrapower generated from waste heat can amount to up to 250 kW.

which is now in series production,

a modular expander family is cur-

rently being designed to allow the

installation of SteamTrac systems

in a wide range of applications.

They vary in terms of number of

cylinders and capacity.

For trucks and buses, Voith Turbo

specific piston expander with a

capacity of 800 cubic centimeters.

In a 40-ton vehicle, it will ensure

fuel reductions of 6 percent and

output increases of approximately

excellently in industrial applications.

In Germany and the United Kingdom,

SteamTrac units have been in con-

tinuous operation in three thermal

power stations for several months.

The performance of the gas engines

has been increased by 7 to 10 per-

cent without requiring extra fuel or

releasing additional CO2.

The SteamTrac has also increased

the output of a barge. The boat sails

between Rotterdam and Duisburg

and supplies the local furnaces with

iron ore and coal. It is fitted with

three diesel engines. For demon-

stration purposes, the SteamTrac

was installed at one of them. The

effect is enormous. Projected for

one year, the fuel consumption per

engine is reduced by 40 000 liters

of diesel. At the same time, the

CO2 emissions are cut down by

106 tons.

A CV-specific SteamTrac is being developed for road vehicles.

In a barge, the SteamTrac allows significant fuel savings.

shunting duties. In future, a total

of 15 Gravitas will be used in

Maschen for shunting and combin-

ing new trainsets. For this reason,

the marshalling yard is more accu-

rately described as a “train forma-

tion yard.” The locomotives working

here have to be able to move 30

or 40 railcars with a weight of

up to 2 000 tons. The train formation

principle works like this: upon entry

into the station, the trains are marked

with “separators” on the basis of a

cut list. The locomotive pushes the

railcars slowly across a so-called

hump. Afterwards the railcars roll

independently toward the intended

sorting siding, the points are set

automatically by a hump control

computer. The speed of the individ-

ual rolling railcars is controlled by

rail brakes. This is how new trains

are combined.

Test Train for the Fifth Generation of Chinese High-Speed Trains

At 500 Kilometers per Hour from Beijing to Shanghai

From 2012, the CRH420 high-speed train will run between the central business district ofChina’s capital Beijing (picture) and the industrialmetropolis Shanghai.

Seven years have passed since the CRH1 was celebrated as the first generation of Chinese high-speed trains

capable of 250 km/h. With the CRH420, the fifth generation is now entering the market. A test train has

already been built: the CIT400. It is expected to reach 420 km/h when in commercial use. Voith participates

in the ambitious project with final drives, automatic Scharfenberg couplers, semi-permanent couplers and

adapter couplers, as well as GFK front end systems.

The eight-car CIT400 – for the

Chinese transport ministry – is close

to its crucial test runs. Come June, it

is expected to whiz along the rails at

500 km/h. If these trials are suc-

cessful, a milestone will have been

reached in the development of trains

that can achieve 420 km/h

in regular service in China. These

super fast trains would be able to run

on the 1 300 kilometer high-speed

Voith Turbo Develops Retarder Specifically for Chinese Trucks

First Trucker in China With Hydrodynamic Retarder


In future, heavy trucks have to have additional and/or continuous brakes in China.

The truck driver, Xiang Lu, drives his truck on one of the eight-lane highways through mountainous territory.

His 3 000-kilometer route leads from Shanghai to Chengdu. A demanding trip with steep downward gradients,

on which the vehicle service brakes quickly reach their limits and run hot. This can result in most serious

accidents. In order to counteract this hazard, Xiang Lu was one of the first Chinese end customers to have his

truck retrofitted with a hydrodynamic Voith Retarder. This makes him a true pioneer on China’s highways.

The problem of hot service brakes

on China’s mountainous roads is

well known. On certain sections, it

is even the police’s duty to cool

down truck brakes with water hoses.

After longer trips, brakes can reach

temperatures of up to 1000 degrees

Celsius. This leads to cracks and

heavy wear. The ensuing risk of

accidents, not least because some

of the vehicles are notoriously

overloaded, has brought about new

legislation: in future, heavy trucks

in China have to be equipped with

a secondary or endurance brake.

Xiang Lu in his 56-ton truck has

not only been on the road without

any accidents, but he is also ahead

of his colleagues. While a number

of large Chinese manufacturers

are still running prototypes of the

Voith Retarder in test vehicles,

the trucker in his Shaanxi truck is

the first one with a hydrodynamic

retarder on board. Xiang Lu, his

brother and his brother in law cover

The three share the vehicle and

are typical owner-drivers, which

make up nearly 60 percent in the

Chinese trucking industry.

On their tours they transport heavy

loads of all kinds: building materials,

steel girders or complete construc-

tion vehicles. There is no fixed route.

Xiang Lu travels all over China,

depending on his transport order.

Chengdu is a frequent destination.

The three drivers often do not see

their families for weeks and, on

average, only come home every

three months – if they happen to

be on the road near home.

Higher Safety on LongDownward Gradients

Voith has developed a retarder

specifically geared toward the

Chinese market. Also Xiang Lu’s

colleagues could profit from the

development. The design is similar

to that of the VR 115 step-up

retarder family, thousands of which

have been installed in Mercedes-

Benz trucks. Through the combina-

tion of engine brake and retarder,

the braking power is significantly

increased, and the retarder is

always fully operational on the long

downward gradients of China’s

highways. Voith Retarders allow

higher average speeds and have

made it possible for Xiang Lu to

move his loads more safely and

more economically.

In 2010, the Chinese market for heavy

trucks (56 tons) has increased by

60 percent compared with the previous

year. In the past year, the ten largest

truck OEMs sold about 1 million heavy

trucks.

At the same time, some 3 500 kilo -

meters of high-speed roads are added

to the network every year to connect

large cities. With 1.6 million kilometers

of highways and 45 000 kilometers

of high-speed roads China is now the

number two behind the USA.

INDUSTRY

The new coupling convinced the Chinese customers during the inspection run in Crailsheim.

The figure alone is almost unthinkable: at present, Chinese mines extract about three billion tons of coal per year.

This statistic from the International Energy Agency makes China the world’s largest producer of bituminous

coal, followed by the USA, India and Australia. And the output continues to increase. In order to meet the country’s

enormous demand, more and more coal has to be mined within shorter and shorter times. During mining

the coal is transported from the seam on armored-face conveyors. For the conveyor drives, Voith Turbo has

developed the world’s most powerful mining coupling with a transmission capacity of 1600 kW – the

CPC 1600 (Chain Protection Coupling).

New Fluid Couplings for Armored-Face Conveyors

Mining Output Increased by More Than Half

The new coupling is a further devel-

opment of the 1200 kW CPC 1200

launched by Voith only about a year

ago. Since their market introduction,

20 CPC 1200 couplings have been

successfully installed in various

Chinese coal mines. In principle,

both couplings have to fulfill the

same requirements: they have to

work reliably under extreme operat-

ing conditions in underground

mines. Both are robust and cope

with rough surroundings, for exam-

ple high amounts of dust and

debris from fallen coal. They are

fill-controlled and use water as

an eco-friendly, non-flammable

operating fluid. The CPC 1600 is

currently the most powerful hydro-

dynamic AFC coupling for OEMs.

In order to achieve this increase in

output, Voith has developped a

fundamentally new geometry of

the runner parts.

INDUSTRY

Armored-face conveyors are the backbonein longwall mining. They transport coal fromthe longwall by means of a circulating chainfitted with scrapers.

CPC 1600 makes coal miningeven more efficient

A coupling of this output class offers

clear advantages to operators: com-

pared to a standard coupling of a

similar size, the transmission output

of the CPC 1600 is 60 percent high-

er. In comparison with the CPC 1200,

the increase in performance amounts

to approximately one third. As a

result of this improved capacity, the

ten to twelve meter high coal faces

in Chinese and Australian mines can

be cut to their full height. In short,

the CPC makes coal extraction

even more efficient, as none of the

seams remain unexploited.

Transmitting 4 MW duringpeak periods

It goes without saying that the

CPC 1600 offers the same advan-

tages as any other Voith hydrody-

namic start-up coupling. It ensures

that the armored-face conveyor

starts reliably, even if fully loaded.

At the same time, the coupling

protects the drive motor against

overloads. If oversized lumps of

coal cause the conveyor to jolt, the

fill-controlled Voith coupling “slips”

as a result of its hydro dynamic

characteristics. This “slip” provides

effective protection for the entire

driveline and especially the convey-

or chain. Should the conveyor be

blocked, the CPC 1600 shows its

particular strength: during several

start-up attempts, it can transmit

a peak output of 4 MW, until the

conveyor finally breaks away. This

output corresponds to the power of

approximately 40 mid-range cars.

Miners appreciate this extra strength,

because they do not have to clear

the conveyor by hand. Additionally,

the coupling increases overall oper-

ating safety, because it is extremely

reliably due to its wear-free power

transmitting capabilities.

Chinese mining operators rely on Voith

During its inspection in front of

Chinese customers, the CPC 1600

proved its function and its efficien-

cy: a test run in Crailsheim demon-

strated that the coupling meets

all aspects of the required perform-

ance profile. In the middle of

January, the coupling was handed

over to one of the leading mining

equipment suppliers in China and

has since then successfully passed

all tests.

Chinese OEMs and mining operators

have been relying on the advan-

tages of hydrodynamic couplings

in armored-face conveyors for

many years. Voith is a regular sup-

plier to Chinese AFC manufacturers

and also provides round-the-clock

service to its customers in China

with its own country-wide sales and

service network, offering installations,

commissioning and maintenance

of Voith couplings.

Hirth Couplings – a Very Special Machine Component

Strong Teeth for Connecting andAccurate Positioning

It often leads a shadowy existence,

and yet, there is hardly a connecting

element that is more versatile than

the Hirth coupling. Transmitting

high torques with a relatively small

diameter – this is one of its major

strengths. This is why Hirth couplings

can be found in pumps, compres-

sors and fans, as well as in milling

machines, gears and turbines.

Voith produces these connecting

elements and also carries out all

calculations and design consulta-

tions. And it was exactly this kind

of know-how that was required for

the latest order to an American

turbine manufacturer.

Masters of transmitting high torques

Voith and the customer jointly

developed the Hirth coupling, created

drawings and carried out, verified

and amended calculations. The

engineering consultation included the

definition of tolerances, preparatory

work on the turbine discs and the

constructive design. The end prod-

uct was a high-strength, quick-

release connection of the turbine

discs. The Voith Turbo plant in

Heidenheim then produced its

largest ever turbine section: the

diameter measures 1100 millimeters,

and the part weighs 800 kilograms.

The key features of the turbine

component are extremely accurate

centering (self-centering) with high

INDUSTRY


Just imagine: 41 600 Formula 1 racing cars simultaneously reach their average torque of 360 Newton meters.

An incredible 15 million Newton meters would be accumulated in this way. A torque volume that an otherwise

fairly anonymous machine component transmits: the Hirth coupling. At the end of last year, Voith Turbo produced

its largest ever turbine section, which was delivered to an American turbine manufacturer in February 2011.

In this particular case, the Hirth coupling on the turbine connects discs with a diameter of over one meter.

The fascination of versatility: from shafts to discs.Customers are offered comprehensiveservice for Hirth couplings: designconsultation, calculations, productionand quality assurance.

concentricity and low radial run-out.

Without these characteristics, dam-

age to the turbine is almost certain.

The end surfaces of both discs are

finished with conical teeth. The

discs are held together by screws

and bolts in a form-locking, self-

centering connection. The force is

evenly distributed across all teeth,

allowing the connecting element

to transmit extreme torques. Hirth

couplings on universal joint shafts

cope with even higher forces,

especially in steel mills. As installa-

tion space in these rolling plants

is usually scarce, the high torque

capacity of the Hirth coupling offers

an enormous advantage. Hirth

couplings also allow modular uni-

versal shaft designs. The removal

from the driveline merely requires

the amount of space taken up by

the tooth height. Further classic

benefits are high wear-resistance

and indexing accuracy. Voith is

certain that there will be numerous

further applications for Hirth

couplings in the future, for example

in turbine construction, for crank-

shafts and in all cases where single

forged parts have to be replaced.

Positioning with hair’s breadth accuracy

Yet Hirth couplings are not only

suitable as connecting elements for

shafts, discs wheels and cranks.

They also function as positioning

elements with astounding accuracy.

Deviations amount to maximally

1 to 2 arc seconds. Such precision

would, for example, allow the posi-

tioning of the wooden horses on

a children’s merry-go-round with a

diameter of 6 m within a distance of

half a hair’s breadth. This degree of

accuracy is required, among other

applications, in machine tool making:

for rotary indexing tables and for

tool carriers. Additional installations

where exact positioning is essential

are medical examination couches

and operating tables.

After all, time is money in the energy

when the Edda Fides docks at an

There are over 4 000 production sites for oil and gas in the Gulf of Mexico and along South America's

shores. The discovery of the mega oil fields Tupi and Jupiter off of Brazil three years ago have

turned the coasts of the USA, Mexico and Brazil into one of the most important oil regions in the

world. New platforms are being built, and correspondingly sophisticated offshore support

vessels are chartered. The reliability, technology, and safety of all personnel and equipment have

first priority, especially after the devastating oil disaster in the Gulf of Mexico.

The M/V Forte is a very special

offshore vessel. Its owner, Edison

Chouest Offshore in Louisiana

(USA), is one of the largest vessel

operators in the Gulf of Mexico.

Petrobras has chartered the Forte

for services in the Gulf where it has

recently commissioned a floating

production ship. Petrobras is the

Brazilian oil company that discover-

ed the above mentioned oil fields

in the Santos Basin off of Brazil

and also conducts operations in the

Gulf of Mexico. Forte has been in

operation since April 2010 and was

initially deployed in support of the

Gulf spill. Now, the Forte directly

supports Petrobras' first FPSO in

the Gulf of Mexico. A key operatio-

nal feature of the ship is active

combination with a direct diesel

drive. The Forte is driven by two

The Gulf of Mexico brings further

performance characteristics of the

ship to the fore: dynamic positioning,

in order to safely maneuver and

position shuttle tankers at the FPSO.

The captain of the Forte can reverse

the Voith Schneider Propellers

electronically within three seconds.

When the waves are particularly

high, the captain can also engage

the VRS, installed for the first time

on this type of vessel. This total

package increases the operational

availability of the Forte in all assig-

ned missions. A loading crane and

a “Stern Roller” turn the Forte into

a multi-functional ship that can

also handle anchors and containers.

With two 1 200-cubic meter water

monitors, equally powerful pumps

and a spraying system, the platform

assist vessel is also suitable for

fire fighting operations.

Over 500 Wind Power StationsAre Already Installed

Since 2002 the experienced instal-

lation company has already erected

over 500 wind power plants and

300 foundations in the North Sea

and the Baltic Sea. Among them is

also the offshore wind park Baltic 1

in the Baltic Sea, which has been

under construction since 2010. When

completed, the wind park will have

21 wind turbines. Each wind turbine

has a rotor diameter of 93 meters.

The hub is situated at a height

of 67 meters. All 21 wind turbines

are connected on sea and land

through more than 77 kilometers

of cable. This ensures the reliable

transport of electricity to house-

holds. In future, Baltic 1 will have

an annual energy output of 176.4

GWh/a.

In order to put up such a plant

safely, heavy steel pipes, so-called

“monopiles” that weigh 500 tons,

are installed up to 25 meters deep

into the seabed with the help of the

installation vessels. This will also

be the task of the “Sea Installer” –

although only to a depth of 20 meters,

which is standard for Baltic 1. With

its jack legs that can be extended

to 105 meters, the “Sea Installer”

can anchor plants in sea depths of

up to 45 meters.

India has been enjoying consider-

able economic growth over the past

few years. Yet a large part of the

population still lives in poverty.

Voith Turbo in India is aware of its

social responsibility and supports

institutions and organi zations that

look after orphans and flood vic-

tims and provide education for girls.

High productivity, an export-oriented

industry and a booming IT business

have converted India from a devel-

oping country into a huge growth

market. This year, the Indian govern -

ment anticipates an 8.5 percent rise

of the country’s gross national prod-

uct. At the same time, more than

one third of the population exists

below the poverty threshold. Apart

from factors such as unequal income

distribution, illiteracy, often very

large families and a caste system,

India’s striking poverty rate is also

due to the enormous population

growth.

A Hot Meal for Children

In 2030, India is expected to become

the world’s most highly populated

country with 1.53 billion inhabitants.

Social Commitment of Voith Turbo in India

Aid for Orphans and Flood Victims

VOITH HELPS


For Indian girls going to school is not typical.

Voith supports several organisations in providing freeteaching materials.

The most blatant consequences of

poverty are health problems such as

malnourishment, unhygienic living

conditions, high infant mortality rates

and short life expectancies.

Voith Turbo in India makes a small

contribution towards improving the

living standards of young people who

do not benefit from the country’s

economic growth. For this purpose,

the management has an annual

budget for social aid. This budget is

distributed to trustworthy institutions

VOITH HELPS


and verified institutions in Hyderabad.

These institutions ensure, for exam-

ple, that orphans find a home, that

girls can go to school or that school

children are given a hot meal as well

as free teaching materials.

Improved Chances in the Labor Market

Voith Turbo in India also ensures

that flood victims receive food and

equips libraries in educational insti-

tutions with technical text books.

In the current business year, Voith

Turbo would like to launch another

project and offer training facilities

for disabled youths, in order to

improve their chances in the labor

market. The young people will

receive theoretical instruction that

is necessary for becoming qualified

craftsmen, such as welders, electri-

cians, machine builders or painters.

Young people should be encouraged and supported.
