Offshore Wind

Offshore wind is a key component of energy transition in Germany and the EU. The European green deal calls for more than 300 GW of offshore wind energy in 2050, which requires about 800 billion Euro of investments. Salzgitter Mannesmann Renewables develops systems for the cost-effective construction of offshore wind jacket foundations, with the particular focus on robotized prefabrication of steel Jacket nodes.

Offshore wind energy will play a decisive role in the turnaround of energy supplies for years to come. By 2030, more than 3,000 newly installed wind turbines in the North Sea and the Baltic Sea are required to fullfill the European green deal. One of the special challenges in such projects is the construction of offshore foundations.

With more than 70%, monopiles hold the largest market share by far. However, greater water depths in combination with challenging soil condition and bigger turbines can call for alternative fundation types such as Jacket structures.

Salzgitter AG's subsidiaries and associated companies have already gained a great deal of experience in offshore wind projects and developed, manufactured and supplied suitable steel products for the construction of foundations. To promote the further expansion of offshore wind energy, Salzgitter Mannesmann Renewables interlinks its own expertise with that of strong industry partners.

In cooperation with our research institute Salzgitter Mannesmann Renewables develops innovative fabrication technologies for our supply chain concept for offshore wind jackets, that can significantly improve the competitiveness of Jackets through prefabricated components. With the offshore wind octagon, we are offering another foundation structure design with significant savings potential for our customers.

To ensure a long service life for offshore wind turbines, we offer specific coatings that reliably protect the steel components from corrosion and wear even under extreme environmental conditions. Mannesmann Line Pipe was also involved in the research project KOWIND which developed a new kind of corrosion protection technology for offshore wind energy foundations. This provides an even higher level of protection, while simultaneously reducing the cost of coating.

Besides their use as tubes for supporting structures, our range of pipe, tube and bends comprises precision steel tubes for high-pressure turbine piping for oil supply to hydraulic components and systems (rotor brakes, locking mechanisms, pitch adjustment, gear lubrication), as well as cylinder barrel tubes and piston tubes
