European projects by Jan Rispens 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 en- countered difficulties. This has changed the face of the industry and led to the overwhelm- ing majority of upcoming wind farms being transferred into the ownership of large energy sup- pliers 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 per- cent 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.

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. www.siemens.com/geafol Answers for energy.

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. 7 OFFSHORE #2 | THE MAGAZINE 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. 8 OFFSHORE #2 | THE MAGAZINE 9 OFFSHORE #2 | THE MAGAZINE 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.
