Next generation vessels: Loading, Transporting
and Installing offshore—all in one
State of the art technology: the joint
venture partners HOCHTIEF Construction
and project and heavy lift
cargo carrier Beluga Shipping are
developing a new type of vessel enabling
installation and maintenance
of offshore facilities with overall
heights of more than 120 meters in
water depths of up to 50 meters.
Power and mobility: 8,000 tons
loading capacity, 1,700 tons crane
capacity, 12 knots service speed—
these special lifting vessels can be
operated flexibly and around the
clock on every single day of the year.
The offshore market is booming,
whereas capacities and adequate
tonnage are short at the moment.
But we have the answer: the first
allround vessel of the next generation
will be launched in 2012.

Foreword
by Jan Rispens
You don’t have to be particularly bold to claim that the offshore wind energy industry will come
through the international banking and financial crisis relatively unscathed. European projects
have reached a volume which is expanding under its own momentum and this will not be stopped
by a temporary lull. Admittedly, projects that depend on banks for their financing have encountered
difficulties. This has changed the face of the industry and led to the overwhelming
majority of upcoming wind farms being transferred into the ownership of large energy suppliers
over the past year. Yet this is of little significance to wind turbine manufacturers and
their suppliers – from gearbox engineering to cabling. It actually gives them a secure basis for
long-term planning, and new contracts for a large number of turbines have been concluded.
On the whole, underlying conditions have indeed been favourable for offshore wind energy – 2009
is the year of the major climate change conference in Copenhagen. Given the increasingly clear
warnings coming from climatologists, Europeans are more determined than ever to reduce their
greenhouse gas emissions. They know they can’t reach their targets without exploiting offshore
wind power. If we look at the political targets for expanding offshore wind power, we see that the
political will still far exceeds manufacturers’ planned capacities. Experts confirm that feed-in tariffs
in Europe and other currently beneficial conditions can generate returns of between 9 and 14 percent
on invested capital. Some 160 offshore wind farms have been built or are being planned around
the European continent, and this figure alone shows that investors are moving with the times.
This is why planners, manufacturers and operators are in an ongoing process of making new
contracts, starting construction, and commissioning wind farms. This holds true for enterprises
in Bremen, Bremerhaven, Cuxhaven, Emden, Rostock and other port cities as well. We are pleased
and proud that a large share of this development is in the hands of researchers and businesses
which are members of the Wind Energy Agency Bremerhaven/Bremen (WAB) network.

Staying on course
in rough seas
In the midst of the financial crisis, the offshore
wind industry is working towards providing a
significant share of Europe’s power.
The industry has seen supply contracts being signed,
mass production plants being opened and expanded,
and ships for building wind farms at sea being
launched. The first large-scale turbines in the five-MW
class have begun operating offshore.
We go into the details of this giant leap.

Is there an ideal interface between
offshore wind power and the grid?
Siemens GEAFOL cast-resin transformers ensure reliability
and efficiency in regenerative energy production.
Even under the hardest environmental conditions, GEAFOL cast-resin transformers withstand
a lot in wind power stations and offshore wind parks. They are flame retardant, self-extinguishing,
and do not develop any toxic gases, even under the effect of an arc fault. This is made possible by
the environment friendly epoxy quartz flour insulation. Moreover, the almost maintenance-free
operation of GEAFOL transformers reduces life cycle costs, while their reduced non-load and short
-circuit losses mean higher efficiency and thus more power for your money.

eurOpe Is backIng wInd pOwer. Some 160 offshore farms are
currently in operation, under construction or being planned around
the coastline of the european continent. They will help eU countries
achieve common climate goals, conserve resources, and reduce
europe’s vulnerability to shortages and fluctuations in commodities
markets. The Thornton Bank wind farm in Belgium is a milestone
in offshore wind energy generation. This was the first commercial
project to go into operation using new five-MW class turbines.
By 2012, three wind farms with more than 846 MW capacity are
set to be built off Belgium’s short 65-kilometre coastline alone.

nature cOnservatIOn and OffshOre wInd. experts on the environment have been involved
in wind farm planning for many years. Migratory birds and porpoises are of particular concern.
The only marine mammals native to the north and Baltic Seas can face harm by noise levels, when
foundation piles are driven into the seabed. For this reason, construction work is scheduled during
periods when few porpoises are in the area, and attempts are made to reduce noise by using new
technologies or installing acoustic barriers around construction sites at sea. after construction is
finished the porpoises are returning to the wind farm area. and sometimes operators have to make
big concessions; in 2005, planning for the Pommersche Bucht and adlergrund wind farms in the
Baltic Sea was stopped to protect marine reserves for various species of ducks on the open sea.

Manufacturers’ art: The offshore wind farms in the north and Baltic Sea are being built under
cooperation of turbine manufacturers, steel companies and shipping companies from all over Central
europe. The multinational industry makes use of conferences such as WaB’s WinDFORCe – DiReCTiOn
OFFShORe to assess current production results of the manufacturers. The spinner of the 5 Megawatt
systems that can be seen on the Repower factory premises are reminiscent of modern art.

energy supplIers. There is a colourful array of planners and investors in
the offshore wind energy industry. Many engineering firms with experience in
onshore wind power have designed and planned offshore wind farms, guiding
these projects through the approval process. Some firms build farms themselves,
while others team up with strong financial partners to see through a project‘s
implementation. But the cost of a project, which can exceed one billion euros, is
often too high for small and medium-sized firms, many of which end up selling
their plans to major european energy suppliers, including german companies like
RWe, e.On, enBW from South-germany or large municipal utilities. They have been
joined by independent power companies, investment companies like Blackstone,
and the Masdar initiative of abu Dhabi. all in all, this makes for a sound mixture
of financing.

At daybreak on 18 September 2008, Alexander Kuhn climbs aboard
a small boat. As it sails out of Zeebrugge harbour, the sun rises over
the southern North Sea and Kuhn’s destination appears over the bow –
six towers at the Thornton Bank wind farm, looking small in the
distance some 30 kilometres from the Belgian coast. Kuhn is among
those responsible for constructing these massive REpower wind turbines.
For days he has been sailing back and forth between the harbour and
the construction site at sea, keeping a watchful eye on the weather.
A high-pressure system called Eric has settled over Europe; it’s a warm
September and there are no signs of autumn storms. But the late summer
is windier than meteorologists anticipated. Eric is changeable, the
weather is unsettled, and gusty winds keep interrupting the work of
Kuhn’s men. Construction on Thornton Bank started two months earlier.
The day before, a crane finally positioned the last of the 77-metre
towers and the nacelle on the 3,000-ton reinforced concrete foundation.
The plan for today is to install the hub with the rotor blades. It’s
a tricky job – the giant star, with a diameter of 126 metres, has to be
raised past the work platform, passing within five metres of its supports.
As the rotor is raised, the sensitive tips of its blades will come
close to the steel struts of the framework supporting the crane. Once
the hub is finally ready to be mounted to the gearbox flange at a height
of 94 metres, the star has to be kept motionless for several minutes.
18
The barge is sailing out to bring the next Multibrid
windturbine to the windfarm alpha ventus.
“Litmus test for the wind industry”
Although Kuhn has already seen the work to completion on five
turbines, he feels responsibility weighing heavily on him now. The
effort of hundreds of people and dozens of firms comes together in
this final moment. “Building Thornton Bank is a litmus test,” says
Norbert Giese, head of REpower’s offshore division. The entire wind
industry is waiting to see whether the six wind turbines off the
Belgian coast will be completed on schedule. It’s a race against time.
Kuhn reckons it will take at least four to five hours to lift the hub and
rotor blades and secure them to the nacelle. The meteorological service
has indicated that stronger winds will not occur until evening, and
installers are making good progress for the time being. They are also
paying constant attention to wind reports coming from the top of the
crane every fifteen minutes. They can keep working as long as wind
speed is less than ten metres per second. But in the afternoon the wind
picks up and the timeframe for installation steadily shrinks. When the
wind gusts at twelve metres per second, the operation is called off.
Night falls and Kuhn heads back to shore with his mission unfinished.
The bad weather does not let up until 19 September, when work finally
goes ahead. Everything runs according to plan, the rotor blades swinging
above the calm sea and gradually rising into the air. The rotor comes to a
halt in front of the nacelle, and at around four in the afternoon a worker
tightens the final bolt in the upper part of the flange. The rotor and gear-

ox are now securely fastened to each other. The work of the crane and
the installers is done. Onboard ship, men congratulate each other, and
some exchange hugs. On the trip back to the harbour, Alexander Kuhn
feels the pressure of responsibility lifting off his shoulders; pleased with
himself and the world, he toasts success back at port with a Belgian beer.
The wind farm on the Thornton Bank shelf is a milestone in offshore
wind energy. Located off the Belgian coast, this is the first time a commercial
offshore project has gone into operation with turbines in the
five-megawatt class. This 153-million-euro investment in an initial phase
to install 30 Megawatt (MW) is the first offshore project for C-Power, a
conglomerate of public and private investors. Belgium has not exactly
been famous for its wind industry in the past, but the fact that it is now
entering the offshore industry shows that confidence is being placed in
offshore wind power as part of the European energy supply mix. Plans
include the expansion of Thornton Bank to 300 MW, and the installation
of three wind farms with 846 MW capacity by 2012 along Belgium’s
short 65-kilometre coastline alone.
Belgium is just the beginning
Energy plans in this country of 10 million people represent just a
tiny part of offshore plans in Europe as a whole. Last December, the European
Parliament passed a resolution stating that the EU will increase
the proportion of renewable sources in the energy supply to 20 percent
OffshOre #2 | The Magazine
by 2020 – an increase of 250 percent compared to 2005. Each country
must submit a roadmap by 2010 and achieve intermediate targets from
2012 onwards. Even for a small country such as Belgium, this means
increasing the percentage of renewable energy sources from 2.2 to 13
percent and achieving six percent as early as 2010. Thornton Bank is
supposed to contribute one-third towards this goal. Because governments
need offshore wind power to achieve their renewable energy targets,
the more populous EU countries are also pressing ahead with the
expansion of offshore wind power. Major power companies, investors
from outside the industry and small project companies are obtaining
new permits around Europe’s coastline on an ongoing basis. The manufacturers
Areva Multibrid, Bard, Repower, Siemens and Vestas are involved
in new projects. Together with their suppliers they are investing
in steel processing, cable production, rotor blade manufacturing and
foundation construction activities in ports on the North and Baltic Seas.
The market for offshore wind turbines with 2.3 to 3.6 MW capacity has
recently received a major boost in the UK. Britain, which aims to increase
its percentage of renewable power from 1.3 percent in 2005 to 15
percent in 2020, has a long coastline, a huge need for renewable energy,
and has put in place a three-stage plan which is being implemented
at full speed. In the initial pilot phase, ten wind farms with a total of
972 MW have now gone online. In autumn 2009, more wind farms with
2,600 MW were under construction and in the second phase, space for
installing 8,000 MW of wind power was put out to tender. There has
19

een other good news from the UK. The Crown Estate, responsible for
the seas around Britain, announced a surprise early start to the third
phase of offshore expansion and said that each of the next eleven sea
areas would be assigned to a general contractor by the end of 2009.
If everything goes according to plan, a further 7,000 wind turbines with
a total installed capacity of 25,000 MW will go into operation in the
United Kingdom between 2012 and 2020. The estimated market volume
is 100 billion pounds sterling or more than 10 billion euros per year on
average. Projects are challenging – as in most German projects, the water
at these third phase projects is more than 25 metres deep, and wind
farms will often be situated dozens of miles from shore.
UK fires the offshore imagination
The UK has already overtaken pioneer Denmark in installed offshore
capacity by implementing the second phase. The UK looks set to occupy
this position for a long time to come. At the same time the government
announced the launch of the third phase, it also made public that the
tariff for offshore electricity would be increased in April 2009 (see table
on feed-in tariffs for offshore power, page 35). As a result, and here
authors of the most diverse studies and forecasts agree, in the decades
ahead the UK will remain the world’s most important offshore market,
and together with Germany will account for around 60 percent of the
global market. These two countries are followed by the Netherlands,
Sweden, Denmark, Spain and Belgium.
“The British government’s mammoth programme makes one thing
very clear: the United Kingdom is clearly relying on offshore to achieve
its ambitious national and European renewable energy goals,” says Fritz
Vahrenholt, head of RWE Innogy in Essen, Germany. RWE also wants to
“help shape [this market] as the leading wind farm operator in the UK”
(see interview page 28).
“The third bidding round in the UK plays a crucial role in the subsequent
development of offshore wind energy,” agrees Gustl-Bernhard
Friedl, who is in charge of Siemens’ offshore business. The German-
Danish manufacturer anticipates slow but steady growth in the offshore
market, with worldwide installation up from 1,050 MW in 2009 to 4,200
MW annually in 2014 (see illustration of Siemens offshore market expectations).
Unlike in the UK, development in Germany was held up in 2008
because of many difficulties encountered regarding projects’ distance
from the shore and water depths. For these projects to be profitable,
they need to rely on the mass production of five-MW wind turbines and
their foundations, and to improve installation logistics. The industry
saw to these steps in 2009. The weather also did not help matters – a
stormy autumn in 2008 scuppered many plans. On 19 September 2008,
the same day that the last turbine was assembled at the Thornton Bank
wind farm, work began on constructing the transformer station for Germany’s
alpha ventus wind farm; the laying of cables to land had been
largely completed. But construction work on alpha ventus itself, the
building of foundations for the flagship project, had to be postponed
until 2009 as weather conditions made it unsafe to work on the crane
ship. There were even problems putting up the FINO 3 met mast, which
was supposed to have been erected by October 2008 some 80 kilometres
west of the island of Sylt. This was delayed until 2009 due to high
swells. It is now finished and installers have learned their lessons; many
businesses are currently developing plans and equipment that will allow
installation even in rough seas.
Other planners were thwarted by the financial crisis. Energiekontor’s
Nordergründe wind farm, with 18 REpower five-MW turbines, could
not be constructed as planned after banks failed to provide the loans
they had promised. “We now want to build in 2010 instead of 2009,”
said a spokesperson. Energiekontor will operate only a few of the turbines
itself, and plans to sell off interests in the remaining ones. Indeed,
the only offshore turbine erected in Germany in 2008 was the
five-MW nearshore turbine installed by Bard Engineering off Hooksiel
to the north of Wilhelmshaven.

Projects in Germany were finally underway early in 2009. Work is
progressing in the Baltic Sea. Contracts for all equipment and supplies
have been signed for the 52.5 MW Baltic I project run by EnBW and wpd,
which will be installed in 2010. In the North Sea, six Multibrid and six
REpower turbines, each boasting five Megawatt, are being erected in
the alpha ventus project. Bard Engineering is beginning the first stage

the German-Dutch sea border; this will be expanded to 400 MW by 2010.
In view of the tight situation in financial markets, support from the
European Commission is coming at just the right time for investors.
According to proposals, the Bard Offshore 1 and alpha ventus projects
in the North Sea, and the linking to the grid of Baltic (1/2) and Kriegers
Flak (1/2/3) in the Baltic are each to receive 150 million euros in
investment subsidies. “We sought out the projects according to their
maturity,” European Commissioner Andris Piebalgs told Offshore magazine.
He said that the tough technological challenges facing the Bard
and alpha ventus projects, based on the turbines’ highly rated capacities
and their location in deep waters, were factors that positively influenced
the decision to subsidise the projects. By the end of the year
2010, more than 500 MW of offshore capacity should be up and rotating
in German waters.
At the same time, British waters remain an important market for
the offshore industry. For the UK in 2009, Siemens is supplying the
Gunfleet Sands project (DONG Energy) with 48 3.6-MW offshore wind
turbines, Rhyl Flats (RWE) with 25 turbines, and from 2009 to 2010
is also providing 140 turbines for Greater Gabbard (Airtricity/RWE). At
the same time, 91 2.3-MW turbines have been installed in the Horns
22
Rev 2 project in Denmark. In the long term, Siemens aims to generate
one-third of its wind energy revenues from offshore turbines and
already sees itself as “number one” for offshore. According to Andreas
Nauen, head of Siemens Windpower, the company is aiming for a market
share of 40 to 50 percent. On this basis, Siemens would have to deliver
offshore wind turbines with a total capacity of more than 1,000 MW no
later than 2012.
Vestas, itself number one for a long time, also appeared back on
the scene at the end of 2008. Its V90-3.0 offshore turbine was taken
off the market for a year following problems with its gearbox and has
now undergone technical revision. At the end of 2008, Vestas was able
to announce that the first turbines of this type would be delivered to
Vattenfall in the UK for the 300 MW Thanet offshore wind farm. Some
57 out of 60 such turbines were installed in the Robin Rigg project in
2009 and will start generating their first offshore power in late summer.
“We’re back!” says Anders Søe-Jensen, head of the Vestas offshore department,
with an eye on the competition. The British offshore market
with its nearshore projects in moderate water depths up to 15 metres
is of particular interest to Vestas, he says. However, Søe-Jensen is giving
nothing away concerning Vestas’ objectives in the offshore sector

REpower in Bremerhaven is more forthcoming: “We want to step up
production to reach 80 to 100 turbines in not more than four years,”
says Norbert Giese, head of the offshore business unit, revealing REpower’s
interim target. In the medium term, REpower is planning to
construct 120 5M and 6M turbines in 2015 and up to 200 additional
units. A team of 40 people is already working to assemble the nacelles
in Bremerhaven.
REpower receives major order from RWE
Norbert Giese is anticipating 10 offshore projects globally on average
each year over the coming years and in February he secured
for his own company one of the biggest deals the wind industry has
ever seen. RWE Innogy ordered 250 5M and 6M turbines from REpower.
The order is worth around two billion euros. The turbines will
be delivered from 2011 to 2015 and RWE is planning to use the first
150 to 180 turbines in the Innogy Nordsee 1 offshore project in Germany

from the factory is not a problem for REpower’s head of offshore. “For our
assembly facility, it’s important that suppliers are close by. Whether the
transport ships head to the UK or the German North Sea doesn’t matter,”
Giese says. He adds that British companies would be in the running especially
for the foundation construction. A similar view prevails at Siemens.
During the construction phase of the Lynn / Inner Dowsing project, six
complete wind turbines at a time were loaded onto an installation vessel
in Denmark and transported directly to the project site off the British
coast. “The distance isn’t all that important. We finished Lynn / Inner
Dowsing ahead of schedule despite the distance,” says Gustl-Bernhard
Friedl from Siemens. He says that this is also why Siemens is not planning
to set up its own production facilities in the UK at the present time.
Areva and REpower currently working to capacity
Areva Multibrid is also staying loyal to its location. “In the
long term we want to supply up to 100 M5000 turbines each
year from Bremerhaven,” says Managing Director Félix Debierre.
The French energy group Areva acquired a stake in the Bremerhaven
company Multibrid at the end of 2007. Up to that time, project planning
for this turbine type was carried out by the Multibrid parent company
Prokon Nord. The first six offshore turbines are now up and running.
The alpha ventus showcase and pilot project produced electricity for
the first time on 4 August 2009. By the end of August, all six M5000
24
turbines had been installed without any major difficulties. Areva also
succeeded in acquiring additional customers for the M5000. Starting
in 2011, the Borkum West II wind farm, which is directly adjacent to
alpha ventus, will be installed using a total of 40 Multibrid turbines
for Trianel in the first stage, a strong consortium of municipal utility
companies. Even though bank financing has become more difficult for
Trianel too as a result of the financial crisis, Niels Erdmann is confident:
“Trianel will raise the financing for Borkum West II,” says the
Prokon Nord wind energy project manager. In the meantime his company
has ordered its own installation vessel for the installation work.
Back in March, Areva signed a binding memorandum of understanding
with the project development company Wetfeet Offshore Windenergy
(Building company Strabag, Stadtwerke München – the municipal
utility of the city of Munich, Hesse utility HEAG) to supply 80 M5000
turbines for the Global Tech I project, due to be completed in the North
Sea by 2012. A special feature of the wind farm, situated in waters 40
metres deep, is that turbines will have a gravity foundation rather than
stand on tripods fixed in the seabed. So far this has been used only
for smaller turbines in shallower waters. Ed. Züblin in Cuxhaven will
supply this 4,500 ton colossus. For comparison, the tower and turbine
together weigh only 1,500 tons. This means for Areva Multibrid that
the production plant in Bremerhaven is currently working to capacity.
There is more good news coming from a place 120 kilometres further
west. Since the end of 2003, Russian investor Arngolt Bekker has been
developing a company that offers
all features of offshore business
from a single source, from
planning services, and the construction
of its own turbines and
foundations, to financing and
operations. In Emden the company
builds wind turbines under
the name Bard 5.0, while in Cuxhaven
it has set up its own factory
for steel foundation structures.
Giant tripiles are now waiting
at the factory to be installed at
the Bard Offshore 1 pilot project
around 100 kilometres off Borkum.
Bard has chalked up an impressive
list of accomplishments
over the last two years. Early in
2008, a shipyard in Lithuania
began building an installation
vessel for the company, Wind

Exciting moments: hauling the star of rotor blades.
Lift 1, as well as an accommodation/transformer platform for the Bard
Offshore 1 wind farm. In August, the first five-MW turbine was installed
close to the dyke at Wilhelmshaven. In May 2009, Bard announced that
following the five-MW turbine, a 6.5-MW turbine is now being planned.
In June, the transformer platform was set up in the North Sea and the
Wind Lift 1 installation vessel was launched from the Lithuanian shipyard.
“The wind farm will be ready by the end of 2010,” confidently
asserts Anton Baraev, head of Bard Engineering. Bard is planning
wind farms in Europe with a total capacity of up to 3,000 megawatts.
The company employs nearly 1,000 people in northwestern Germany.
Despite this diversity, the offshore manufacturing scene is still relatively
uncluttered. Around 160 wind farms are currently
at various stages of planning in Europe, and there is
much greater variety among investors than among
manufacturers. Other energy companies in addition to
Airtricity, Bard, Blackstone, Enertrag and wpd, energy
utilities are now also planning projects worth hundreds
of millions of euros; RWE, E.ON and EnBW from Germany,
Vattenfall from Sweden, Dong from Denmark and EDF
from France are particularly active. Essent and Nuon in
the Netherlands have now been taken over by RWE and
Vattenfall respectively. Even Masdar, Abu Dhabi’s global cooperative
platform for sustainability, is involved in the London Array project
which is currently the world’s largest planned offshore wind farm.
Large companies like these are not only used to investing money in
the orders of magnitude required offshore in connection with their fossil
fuel power station projects, they are also the ones who, because of
high profits in the energy market and the securities that are available,
have the least worries regarding the financial crisis; following the credit
crunch the banks have tightened their requirements for the equity ratio
from the expected 30 percent to as much as 50 percent at the present
time, while interest rates have also gone up.
“Like winning the lottery”

The wide variety of offshore countries, manufacturers
and investors means that a flood of demand is predicted for
which suppliers are now preparing themselves. The fact that
the European governments’ targets far exceed manufacturers’
capacities also gives manufacturers some certainty.
Take the example of Cuxhaven. Back in 2007, Cuxhaven

production of large-diameter tubular segments and other parts with
large diameters and high component weights for towers and foundations
– all for the offshore industry. In January 2009, Ed. Züblin announced
that as a construction company it was investing a triple-digit
million sum in Cuxhaven to produce concrete foundations for offshore

wind power stations. This is set to create 500 new jobs in the short
term. The State of Lower Saxony is also completing an offshore wharf
in Cuxhaven at a cost of 50 million euros. “For Cuxhaven the investments
in offshore wind energy are like winning the lottery,” says Mayor
Arno Stabbert, who is delighted with recent developments and already
sees the city of 50,000 at the northernmost tip of Lower Saxony as being
a “European centre” for the construction of offshore foundations.
Cuxhaven isn’t the only city with a feel-good factor. Emden has been
home to Bard Engineering’s production facilities since 2005. Bremerhaven
has now started advertising itself as the “home port of the
wind industry”. In this city on the Weser estuary, a close-knit network
employing a total of more than 1000 people has formed around the
manufacturers Areva Multibrid and Repower. The City also comprises
researchers such as the Fraunhofer Institute for Wind Energy and Energy

Power Blades, a joint venture between REpower and SGL ROTEC,
has been producing rotor blades since August 2008 for the REpower
MM92 and the new RE 3.x onshore turbines in factory buildings that
are up to 456 m long. More than 200 people are employed here, and
the plant, with its direct access to the port, has the capacity to produce
300 offshore rotor blades per year. “We will produce the first prototypes
for the 6M offshore turbines at the end of 2009,” says Managing Director
Lars Weigel. “Because we are able to produce both onshore and
offshore blades in our facilities, we don’t have any capacity utilisation
problems if the offshore projects get delayed. We can shut down
the onshore capacities if we need them to produce the offshore rotor
blades.” When it needed the rotor blades for Thornton Bank, REpower
was still buying them from LM Glasfiber in Denmark. Its own offshore
capacity is to be expanded to 100 blade sets by 2011. At the centre of
this wind energy industry in Bremerhaven, but also with many members
in the whole of Northwest-Germany, stands the industry network
organization Wind Energy Agency Bremerhaven/Bremen (WAB).

“at least a billion euros per year
for renewable energy”
Offshore magazine: the uk
has announced a new round of
tenders for the expansion of
offshore wind power. is rWe
bidding for more wind farms?
Vahrenholt: Of course. For the
third round we have formed a
strong bidding consortium with
airtricity/SSe, Statkraft and Statoilhydro.
With our know-how,
expertise and financial strength,
we’ve got a good starting
position in the upcoming award
procedure. if we are successful
and obtain approval to develop
zones in the third round, we want
to work together on building the
wind farms.
at the moment we already have
a strong presence off the British
coast and we operate the UK’s
first offshore wind farm, north
hoyle. We want to connect
Rhyl Flats to the grid this year,
which is 90 MW. The offshore
work for the greater gabbard
wind farm, which will generate
around 510 MW and in which we
have a 50 percent stake, is also
starting in 2009. We have nearly
all the necessary permits for the
750 MW gwynt y Mor wind farm.
Together with Seaenergy we’ve
also got the green light from the
Crown estate for plans to build an
offshore wind farm with around
900 MW. On top of this, there are
plans to install another 2000 MW
in the UK.
rWe is getting involved in
german offshore development
with an enOVA project, innogy
28
Shortly after leaving REpower to become CEO at RWE Innogy, FRITz VAhREnhOLT
announced ambitious plans for the offshore business. Never mind the future of the
group’s nuclear power stations – the future belongs to renewable energy. RWE aims
to operate 4,500 MW. Vahrenholt is now even considering acquiring his own installation
vessels for offshore.
nordsee 1. When are the first
installation vessels going to
be sourced and the first supply
agreements signed – aside from
the framework agreement with
repower?
The framework agreement with
Repower concerns the delivery of
up to 250 offshore wind turbines
in the five and six-megawatt
class. incidentally, with a
potential volume of around two
billion euros this is the largest
contract that has been concluded
to date for offshore wind energy
use. With this agreement we have
secured the 150 to 180 turbines
that are required for innogy nordsee
1. The possible increment
to 250 turbines will help us to
implement further projects in our
offshore pipeline – for example
in the UK or the netherlands. Of
course we are also in talks with
other companies concerning supply
contracts.
For the construction vessels we
also wanted to be on the safe side
and are therefore looking at various
options. One is to procure our
own ships that are designed to
meet our exact needs and, above
all, that we would be able to use
flexibly.
Are you sure that you can
achieve your target returns with
the current payment rates for
offshore power? A figure of 15
percent is often quoted here.
Our targeted returns are ambitious,
but they are still below 10
percent. if we couldn’t achieve
this, we wouldn’t be investing.
RWe is a stock exchange listed
company that is careful in the use
of its investment funds.
Will rWe still build the wind
farm if the operational terms
of the nuclear power plants are
extended?
Of course we will. The future
belongs to renewable energy
and RWe is pursuing a very clear
growth strategy. We are aiming to
have 4,500 MW under construction
and in operation by 2012. if
turbines run at average capacity,
this works out at around 15,000
gWh of power generation per
year. however, we need nuclear
power to give renewable energy
sources sufficient opportunity to
develop. Our neighbours in Denmark
or italy, for example, have
clearly understood this. if the
nuclear power stations in germany
were shut down tomorrow,
then to a considerable extent
they would have to be replaced
with conventional technology.
That would mean an additional
150 million tons of CO2, which is
roughly as much as all the road
traffic in germany emits in a year.
What do you consider to be
the most important difference
between the german and uk
markets?
The structure of the funding system
is completely different and
the way the wind farms are connected
to the grid is regulated
differently. another major differ-
ence is the distance of the wind
farms to the shore. Compared to
the UK, in germany we have to
build farms a relatively long way
from the coast in deep waters.
Just one example: our British
wind farm north hoyle is situated
eight kilometres from the coast;
Rhyl Flats is currently being built
right next to it. By contrast, innogy
nordsee 1 is being built 40
kilometres north of Juist island.
This creates even greater challenges
for planning, implementation
and technology.
is rWe still looking for more
projects in germany?
Our target of 4,500 MW under
construction or in operation by
2012 relates to europe. germany
is an important market here, i’m
not ruling anything out.
is the financial crisis making it
more difficult for rWe as well to
obtain offshore financing?
By 2012 we will invest at least
one billion euros every year in
renewable energy. We are sticking
to this – there are no ifs and
buts. We are able to do this as a
result of the solid cash flow from
RWe.

Reaching higher and higher to harness more wind, your wind farm power
plant should be on a solid foundation.
With over 40 years experience in off shore rig installation we can safely say,
no depth is too deep, no pile too wide, no project too large.
Our complete hydraulic hammer systems:
■ deliver energy from 100 kJ to 3000 kJ in diff erent hammer sizes
■ use a double acting system (hydraulically accelerated ram)
■ dive underwater up to 2000 m and deeper
■ drive large monopiles up to 5.2 m (larger OD planned)

“This location has charm”
Offshore magazine: What motivates
a financial investor like
blackstone to invest in offshore
wind power?
Jens assheuer: in the first
instance the private equity industry
is interested in the size of
the investment. We have a project
volume of more than one billion
euros here, with an equity capital
requirement of several hundred
million euros. These are the usual
orders of magnitude for private
equity firms like Blackstone.
What made you choose, of all
things, one of the most ambitious
projects? 400 MW, 80 km
from the shore – couldn’t you
have found an easier project?

that, the equity capital requirements
for such projects are

Just in from northwestern Germany, JEnS ASShEUER arrives at Berlin’s central railway
station in a relaxed mood. A meeting has been cancelled in Berlin, which means we can

the offshore plans of his majority shareholder Blackstone from New York.
too small for an investor like
Blackstone. So the question
never arose.
What are the plus points of
Meerwind?
Water depths of 22 to 26 metres
are very moderate in comparison
with 40 or 45 metres in other
projects – this is reflected in
the design and the costs of the
foundation structures. We are
only 12 nautical miles away from
heligoland, which means we can
carry out servicing and repairs
from the island. Our reaction
times are less than an hour. We
would have to allow five to six
hours by boat from the mainland.
This location has charm.
how many installers and
technicians will you station on
heligoland?
We want to operate the wind farm
ourselves from the outset and
also carry out maintenance and
repair work ourselves. We won’t
know the exact number of techni-
cians until our maintenance and
service plan is finalised.
You compared a large number of
projects before the purchase in
July 2008. how do they differ
from each other?
Because the feed-in tariff under
the german Renewable energy
Sources act (eeg) varies according
to the distance from the
shore and water depth, there is
no longer any easy distinction
between good and bad projects.
The eeg does a good job of
evening that out. The status of
project development was more
important to us. if you buy a
project today, the earliest you
can build in 2012. The investors
have to come up with significant
supplier contracts and financial
resources before transpower,
formerly e.On netz, will lay the
grid connection in the north Sea.
This work has a lead time of up
to 36 months. The timeline is the
most critical point.
MeerwInd Ost/sÜd OffshOre wInd farMs
The Meerwind Ost/Süd offshore wind farms (Meerwind) are situated 12 nautical miles (23 kilometres)
to the north of heligoland and 50 miles (80 kilometres) from the north German coast. WindMW, based
in Bremerhaven, is responsible for the planning. Blackstone has an 80 percent stake in the company
and Windland Energiezeugung owns 20 percent. The project was granted approval by the German
Federal Maritime and hydrographic Agency (BSh) in hamburg on 16 May 2007. The nordsee Ost (Essent/RWE
Innogy and Amrumbank West (E.On) wind farms are situated directly next in the north to
Meerwind. Their shared power transmission line will be routed via the Brunsbüttel connection point.
The Meerwind project is formally divided into two wind farms. In each case 40 turbines with 3.6 or
5 MW are to be constructed in Meerwind Ost and Meerwind Süd. The project is being funded via a
project financing model. WindMW engaged KfW-IPEX and dexia to prepare the project financing.
What is the range of annual full
load hours that can be attained
and what is your estimate for
Meerwind?
The equivalent full load hours are
in the region of 3,800.
since blackstone’s involvement
was announced in summer
2008, nothing more has been
heard about the project. What
stage is the technical planning
currently at?
There have already been talks
and negotiations with the main
suppliers, and the plans for
maintenance and operation have
progressed well. We have also
begun preparing everything to
satisfy e.On’s grid connection
conditions and hence secure a
promise of a grid connection.
Which wind turbines will be
used? Originally 3.6-MW turbines
were planned.
We are investigating both a 288
MW and a 400 MW option.
do you see any big differences
between manufacturers?
The turbine manufacturers have
not yet come as far as they should
have done. They have not ramped
up capacities sufficiently yet and
their sub-suppliers also have not
made sufficient investments. Besides
that, the turbines’ test run
times are too short. One to three
years of operational experience
is not much for a technology that
is supposed to withstand more
than 20 years of extreme weather
conditions.

Aren’t the risks too high to be
starting out with an immature
technology?
Then we wouldn’t have bought
the wind farm [laughs]. We are
convinced, and we will also verify
this with our engineers, that the
reliability of turbine technology
will keep improving over the
years ahead. So don’t worry.
We are taking out insurance
for the event that three or four
gearboxes break down. What you
can’t do is insure all 80 turbines
against serial losses. in the
event of a serial loss, the wind
turbine manufacturers must find
a solution together with their
customers.
there have already been serial
losses in a number of offshore
wind farms. Wouldn’t it be a
good idea to invest your equity
somewhere else?
You have to assume that risk if
you want to build a wind farm.
The turbine manufacturers must
be held to account in that case.
planning for other offshore
projects has been put on ice
because of the financial crisis.
blackstone has lost one-third of
its stock market value. how is
the crash in the finance industry
affecting you?
it’s definitely difficult in the
current climate to get project
financing from the banks. But the
market will stabilise again and
the project financing business
will also pick up again. The only
thing you can do at the moment
is take a clear-cut and professional
approach, distribute the
risks sensibly in the project and
involve the banks and insurance
companies in the contractual
negotiations from the outset so
that all contracts are bankable
from the beginning. Then you will
get money straight away as soon
as lending starts again.
When will that happen?
it’s impossible to say.
You won’t lose your money?
Blackstone supplies the equity
capital as a shareholder in the
company. That is assured and
the money is available through a
closed-ended fund.

a sOlId fInancIal basIs
The offshore industry in Germany can rely on a high feed-in tariff and a stable political framework.
The amended Renewable Energy Sources Act (EEG), which came
into force in Germany on 1 January 2009, increased the feed-in tariff
for offshore wind power. The act ensures that all turbines put into
service before 1 January 2016 receive 15 euro cents per kWh of windgenerated
electricity. This rate is valid for a period of 12 years for all
turbines. To promote the construction of wind farms that need to be
built even further offshore and in even deeper waters, the basic feedin
tariff is supplemented by an extension of the period of payment.
Turbines located more than 12 nautical miles from the coast in waters
at least 20 metres deep benefit from an extension of half a month’s
payment for every full nautical mile additional distance from shore,
and an extension of 1.7 months for every additional metre of water
depth. For example, a wind turbine sited 30 nautical miles from the
nearest shore in water 40 metres deep receives a feed-in tariff of 15
euro cents per kWh for 18.7 years. Hence the payment period for
most German offshore wind farms is in the region of 20 years, which
puts them on an equal footing with the onshore wind industry.
The tariff per kWh falls by five percent per year starting from 2015.
32
Alongside the calculable, fixed feed-in tariff, a second line of support
in Germany is provided by an act to accelerate infrastructure planning.
This Infrastructure Planning Acceleration Act enshrines in law that the
power grid operators transpower stromübertragungs gmbh (former E.ON
Netz) for the North Sea and Vattenfall Europe Baltic Offshore Grid GmbH
(VE BOG) for the Baltic are to construct the power grid for the offshore
wind farms at the request of the wind farm operators – so-called power
points at sea. As a result, operators should save between one-fifth to
one-third of total investment costs.

§ 31 Offshore wind energy
(1) For electricity from offshore turbines the feed-in tariff is 3.5
euro cents per kilowatt hour (basic rate).
(2) In the first twelve years from the time the turbine is first

kilowatt hour (initial rate). For turbines that are first put into

1 increases by 2.0 euro cents per kilowatt hour. The period
in which the initial rate is paid as per sentences 1 and 2 shall

Annual adjustment in the SDE regulation; SDE means Stimulering Duurzame Energieproduktie. Operators receive a supplement per kW/h on top of
the market price, but this figure hasn’t been determined yet. The government published in the summer of 2009 a draft ruling on the granting of
project licenses for the North Sea, and the SDE tender will be discussed starting in November 2009, with a decision expected in April 2010.
In the Netherlands the financial support for all renewable energy sources is specified in the provisions of the SDE regulation. Under this SDE
financial support scheme producers receive, on top of their market price revenues, a premium per kWh produced.
The Dutch government will provide support for a total of 950 MW offshore wind power in the period 2007 - 2011. This will bring the overall
offshore wind capacity in the Netherlands to a level of 1178 MW. Contrary to the approach followed for other renewable energy sources, the exact
level of the SDE financial support for offshore wind energy has not yet been determined, but will result from a tender approach which is open to
license holders only. The government published draft-decisions on applications for licenses to build offshore wind farms in the Dutch part of the
North Sea in the summer of 2009. It is foreseen that the SDE tender will be opened as of 1 November 2009 with decisions expected around 1 April
2010.
Market price + green certificates (until 2030) +
environment bonus (2009). The average annual
market price in 2007 until July was 229.23 SEK/
MWh (2.49 cents/kWh). Operators also receive
a certificate for every MWh. Energy suppliers
are obliged to produce a certain number of
certificates every year. The number of certificates
is determined by the volume sold the year before
and the quota specified by the government each
year for the share of renewable energies desired
in the overall energy mix.The time limit set for
certificate trading was extended from 2010 to
2030. With that, the remuneration in 2007 was
about 6 - 7.5 cents/KWh; an additional budget for
investment subsidies for new offshore wind farms
amounting to some 350 million Swedish krona
(37.5 million euros) was accorded for 2008 - 2012.

rave – research
at alpha ventus
A research initiative by the German Ministry for the Environment (BMU)
36

The German Ministry for the Environment is providing 50 million euros
over the coming years to fund research into offshore wind energy at
the alpha ventus test site.
The Institute for Solar Energy Supply Technology (ISET) in Kassel
is heading the coordination project in which individual associated
research projects can be networked and represented. The alpha ventus
test field is equipped with a wide range of measurement systems to en-
RAVE Research Projects
able detailed data to be supplied to all the projects involved. The most
important task of the coordination project is to give a strong structure
to the shared programme for the associated projects. In order to be
able to exploit synergies and raise the quality of results, a coordinated
plan was developed for collaboration between the various projects in
the test field.
Within the research programme as a whole, various institutes and
companies have so far undertaken projects on the following themes:

Measurements and data management Federal Maritime and Hydrographic Agency of
Germany BSH
Development, construction and operation of alpha ventus
Development and optimisation of offshore turbine components with regard to costs, REpower Systems

strong winds also in coastal areas
The proximity to the coastline is not a
critical factor for the profitability of an
offshore wind park, as demonstrate comparisons
of coastal distances to annual
full load hours. This is, however, where
you can clearly see the advantage of offshore
wind power. With about 40%, these
plants boast twice the capacity factor of
plants in the german inland.

IMS Ingenieurgesellschaft mbH
We are consulting engineers for offshore technology. We plan offshore wind farms and, amongst other things, draw up all technical documentation
for our customers required for approval procedures according to the BSH standards. Our core business is the design and construction
of foundation structures for offshore wind turbines and offshore transformer platforms.
Founded in 1972 under the name “Ingenieurgemeinschaft
Meerestechnik und Seebau” (Engineering
Company for Marine Technology and
Construction), IMS has its roots in offshore
technology. For this reason, although offshore
wind energy certainly represents a new challenge,
we can draw on a wealth of experience in
meeting this challenge that stretches back more
than 30 years – experience that we are pleased to
share with our customers.
Offshore wind farms with 80 or more wind turbines
represent large-scale infrastructure projects.
We advise our customers in realising these
projects and
can also draw on the expertise we have acquired in
planning and constructing large-scale infrastructure
projects on land, such as for example land reclamation
projects for Airbus in Hamburg. In the field of
offshore wind energy we have been involved in more
than 50 projects to date. For example, we draw up
approval procedure documentation in accordance
with the BSH standard for construction:
− Design basis for foundation structures and transformer
stations
− Preliminary designs for foundation structures and
offshore transformer platforms (deck structure
and foundations)
− Collision analyses for foundation structures for
offshore wind turbines and transformer stations.
Water
depth
[m]
Our core business is the design, construction
and measurement of foundation structures for
offshore transformer platforms. Here we carry
out the complete project planning and structural
design ready for implementation. This also
includes drawing up tender documents.
A further focus of our work is planning and
monitoring offshore installation work. For the
particular demands of offshore wind farms we
have also developed special equipment such as
large scale jack-up platforms for constructing the
farms.

“We will produce the first prototypes for
the 6M offshore turbines at the end of 2009,”
says Managing Director Lars Weigel. “Because we are able to
produce both onshore and offshore blades in our facilities, we
don’t have any capacity utilisation problems if the offshore
projects get delayed. We can shut down the onshore capacities
if we need them to produce the offshore rotor blades.”

Wind generates Work
Counting only the major companies, offshore wind power has created nearly 3,000 jobs in recent years.
In particular, the state governments of Bremen/Bremerhaven and Lower Saxony have sought to provide land
and infrastructure for new businesses. What has not been counted are the many jobs in small and medium-sized
regional service providers and suppliers.

Installation vessels, or the lack of them, will be a bottleneck in the construction of offshore wind farms
in the years ahead. This is why a number of companies have decided to become independent of shipping companies
by acquiring their own vessels. However, ship lenders are also expanding the range of ships on offer.
Here is an overview of new developments.

Wind turbines
for the high seas
Wind turbines installed offshore are much larger and more powerful
than those erected on land.
The high cost of support structures needed in waters that are 40 metres
deep or more makes them too expensive for smaller turbines. Turbines in
the two-megawatt class are used only in projects closer to shore, but there
are no such sites in germany’s territorial north Sea. Turbine manufacturers
are now designing bigger turbines for deeper waters, with capacities
between 6.5 and 10 MW.

new power grid
for Offshore power
Transpower stromübertragungs gmbh (former e.On netz) is providing
the power link from the first wind farms in the north Sea to the mainland
grid. a legal framework for this task was set by the infrastructure
Planning acceleration act passed on 24 november 2006. Under this law,
grid operators on the coast must see to linking wind farms off the coast,
“power points at sea”, with the mainland. e.On and Vattenfall are responsible
for this in grid linkage in germany’s north- and Baltic Sea area.
Since 2007, Transpower has commissioned labour and construction
worth more than 400 million euros to connect wind farms like alpha
ventus and Bard Offshore 1 to the grid.
MOnItOrIng and cOntrOl
Safeguarding offshore power generation requires remote monitoring
and control capability on land. BTC, an IT consultant firm
located in Oldenburg and member of WAB, negotiated a contract
with the alpha ventus project to create an integrated IT network for
individual turbines manufactured by REpower and Multibrid; this
also covers process monitoring and control from a control room,
and integrates technical management as well, whether for planning,
administration or the documentation of maintenance done
on wind turbines and transformer platforms. This system is entirely
new in the market. Although individual turbines have software
tailored especially for technical monitoring, a plan for the alpha
ventus project which allowed overall manufacturer-independent
control and management had to be set in place to optimise turbine
management and ensure that power be reliably fed into the grid.
OffshOre #2 | The Magazine
The grid link for alpha ventus was completed early in 2009
(through a 110-kilovolt three-phase link). The power line from the
wind farm to the feed-in point at the new hagermarsch transformer
station (near the city of aurich) is about 70 kilometres long. it runs
via the island norderney and the Wadden Sea national Park of Lower
Saxony. Strict conservation regulations were imposed during construction
to ensure there was no threat to plants and animals in the
reserve. The offshore transformer station, where power from 12
wind turbines is collected, has been in place since September 2008.
To reduce conduction losses, a 200-kilometre high-voltage DC transmission
line was built from the 400 MW Bard Offshore 1 wind farm – a world
premiere. alternating current is converted to direct current at the wind
farm’s transformer platform and then converted back to alternating current
on land. The entire transmission system has been designed to link
several wind farms.

The optimisation of the foundations has been driving the engineers
since the initial concept sketches for offshore wind farms. The steel
and concrete footings have to provide a secure foothold while being as
cost-effective to manufacture and assemble as possible. This leads to
various solutions for different wind farms: For a long time, the simplest
case was so-called gravity foundations where the extended tower of the
wind turbine was anchored into the seabed via a concrete base. With
ever larger turbines and increasing water depths, engineers discovered
that monopiles, where the extension of the tower is driven directly into
Tripile Cuxhaven Steel Construction Jacket WeserWind

the ground, are the best solution. For greater water depths and larger
turbines with 5 MW or more – especially in the German North Sea – various
types of multi legs were developed. Depending on the steel price,
assembly technology and philosophy, companies started using different
models. Most recently, engineers have also been using gravity foundations
for wind turbines with 5 MW and more. With their 4500 tons these
concrete footings now weigh more than five express train railcars. For
water depths beyond the 50 meter mark, new systems are being created
which allow for a floating attachment of the wind turbines.

MOVeMent On the cOAst
With production focussed around
Bremerhaven, Emden and Cux-
haven, Germany’s north-western
region can supply almost every-
thing the offshore wind energy
industry requires.
62
The new Klimahaus ® 8° Ost seems to float
like a balloon over the Bremerhaven seaside.
Whether by accident or design, the city which
for several years has been bustling with growth
from an ever-increasing number of businesses
in the wind industry now has a futuristic centre
to experience climate change and the need
for climate protection. Meanwhile, climate
protection on a wholly practical level thrives
in the Luneort industrial area, where Repower
and Multibrid factories are located within
sight of each other. These are two of only three
manufacturers in the world who build wind
turbines with a rated power of five MW or more.
Together they intend to produce at least 200
turbines in the multi-megawatt class each
year. if the annual rated power of this capacity
is added together, the offshore industry in
Bremerhaven alone provides more than the ca-
pacity of a large nuclear power plant each year.
Suppliers such as SgL Rotec and WeserWind
Offshore Construction georgsmarienhütte are
also here. The research community has most
recently been joined by Deutsche Windguard
with its wind tunnel, and the Fraunhofer institute
for Wind energy and energy System Technology
(iWeS), with a test facility for 70-metre
rotor blades. in 2010 a second test facility will
be built for blades of the future – 90 metres
long and with blade weights of up to 50 tons.
Bremerhaven’s harbour, the vital link between
manufacturers’ production facilities and offshore
construction sites, has also seen development.
Since the summer of 2009, quays
for heavy loads have become available at the
fishing port, enabling manufacturers to ship
out nacelles, tower segments and foundations
weighing several hundred tons.

Cuxhaven – investment in the Offshore Basis
The Offshore Basis Cuxhaven has developed at a fast pace in the past two years. Since 2006, the
State of Lower Saxony, with eU support, has invested more than 80 million euros in infrastructure
for the Offshore Basis, and there have also been more than 100 million euros of private investment.
Close to the port, where a few months ago sheep were still grazing on the dyke, the site is
now home to aMBaU and Cuxhaven Steel Construction production facilities.
The new offshore terminal was built next to production sites on the elbe river at a point deep enough for oceangoing
ships. The offshore terminal was planned and built in just 18 months by niedersachsen Ports. Officially
opened on 20 March 2009, this is the first port anywhere on the entire north Sea coast to be designed specially
for shipping large offshore foundations, towers and other components.
at the nearby offshore heavy load platform on the europakai quay, which was completed in early 2008, the first
offshore foundations have already been loaded onto ships. The FinO 3 research platform was also loaded from
the heavy load platform in early 2009. The heavy load platform offers excellent capabilities for all construction
logistics needed for offshore wind farms in the north Sea.
The port infrastructure for the offshore industry in Cuxhaven prompted ed. züblin to begin building facilities to
mass produce gravity foundations from late 2009 onwards. The arrival of ed. züblin and other businesses in the
offshore industry will help create at least 1,500 new jobs in Cuxhaven by 2013. Located only 40 kilometers from
eachother, Bremerhaven and Cuxhaven together form the heart of offshore wind development in germany.
emden and Cuxhaven have also seen massive
expansion in their offshore industries.
norddeutsche Seekabelwerke (nSW), across
from Bremerhaven in nordenham, has invested
some 40 million euros in a new production facility
for submarine cables sited directly on the
bank of the Weser river. From here, submarine
cables can be moved directly to a special cable
ship. Since early 2009, hundreds of workers
have been manufacturing cables for the alpha
ventus wind farm’s internal linkage, Roedsand
2 (expansion of nysted/e.On) in the Danish
Baltic, and Bard Offshore 1 in the north Sea.
nSW in 2009 also supplied the island of heligoland
with its first link to the mainland grid
in Schleswig-holstein. nSW has invested in a
cable-laying platform, the nOSTag 10, used in
projects to lay submarine cables.

Connecting you
Since 2002, the Wind Energy Agency Bremerhaven/Bremen (WAB), which is partly
funded by the City of Bremen, has formed a network of businesses, researchers and public
authorities in the wind energy industry. More than 200 members have now joined the
WAB network, and membership keeps growing.
nearly all relevant businesses, institutes, government agencies and
research institutes, from emden to hamburg and Cuxhaven to hanover,
are WaB members. The Wind energy agency is a networking resource
and a door-opener. anyone new to the region can contact locally based
companies through the team at the WaB office. established businesses
use the events staged by WaB to exchange information and experience
within the industry. The offshore wind energy conference organised by
WaB, “Windforce – Direction Offshore”, has now become an established
date in the event calendar of offshore companies in germany and other
countries.
64
apart from offshore wind energy, WaB focuses on education and training,
the repowering of old wind turbines in northern germany and the
internationalisation of the industry. in addition to producing magazines
and brochures relating to its focus areas, WaB sends its members
a regular newsletter with important wind energy news from the region
and the european offshore wind energy sector.
But there is one thing above all else that WaB offers its members –
excellent connections with businesses and decision-makers in industry
and public administration in the region.

Europe’s
energy future
how electric cars and
offshore wind power came together
hamburg, 2030. The small cars of hamburg’s moneyed classes are
swarming past the big power point on the bank of the alster. it was
around 20 years ago that the first legions of electrically powered cars
produced by BMW, Volkswagen and Smart started to appear on germany’s
roads. Back then, there were only 1,436 electric cars out of a
total of 41,183,594 registered vehicles. Most cars ran on petrol or diesel
– evil-smelling liquids with dubious origins and an absurdly bad
ecological balance. But the first oil price shock of the 21st century
finally forced the government to take a serious look at alternatives
to this waste of resources. electric cars seemed to offer a solution.
But studies quickly showed that “if additional electricity needs are
generated from coal-fired power stations, an average electric car will
66
produce up to 220g of CO 2 per kilometre,” as environmental organisations
calculated. That could have put an end to this new dawn for the
electric car. But the association of german power generators had recognised
at the time that “wind energy alone would be able to replace
all petrol consumption in germany.” Then some scientists came up with
the brilliant idea of making drivers buy all the fuel for the car at the
time they purchased the car itself. Power grid operators realised that
in this way, especially in the cities of northern germany, they could
acquire customers who would be certain to buy surplus wind power.
The result is that today, in zero-emission cities such as hamburg, no oldfashioned
combustion engine vehicles are allowed past the electronic
city wall that keeps the polluting dinosaurs out.
