Project “Megawind” on the upswing:
Siempelkamp Foundry is awarded Siempelkamp Foundry is contributing towards the new means of energy conversion in a highly specialized industry. This has been noted across the industries. In 2010, IHK Mittlerer Nieder rhein (the Chamber of Industry and Commerce of Middle Lower Rhine) awarded the Research and Innovation Prize to the company: they achieved first place for their new material for structural components of wind turbines. By Dr. Silke Hahn
he prize, which is awarded every three years, was presented to Siempelkamp for the development of a cast iron material specially customized for wind power. This development enables the construction of new and even bigger offshore wind turbines. These wind turbines, which are already today provided by Siempelkamp with ductile cast iron components and are so far mainly set up in the North Sea, are the champions of wind turbines. The turbines have brought about partic ular challenges for the industry: the generators must be very resilient and the technology must be particularly rigid and reliable. “In addition, the foundations in the sea – i.e., the anchoring and base – must be significantly deeper and denser than onshore. An ideal wind generator combines greater stability with low weight,” explains Stephan Kaiser, Managing Director of Siempelkamp Giesserei GmbH.
Greater stability, less weight How is it possible to combine the greatest stability with the lowest possible weight? For years, materials experts at Siempelkamp Foundry have been dedicated to answering this question relative to wind turbines. The challenge lays at the upper end of the turbine – at the nacelle, the

Machine carrier for 7.5 MW onshore wind turbines
Rotor hub and machine carrier waiting for transportation
Tuning the material to gain a com petitive edge The weight of the components supplied by Siempelkamp for the wind turbine nacelles alone could be potentially reduced from the current 65 to 52 t. With the reduction in weight, savings can also be made at the turbine tower itself and in the foundations. For Siempelkamp customers, this means an increase in efficiency of the entire turbine – thus resulting in a com petitive edge.
From left to right: transport of a 46 t machine carrier and a 36 t rotor hub
This concept also convinced the IHK jury: in the presence of the North Rhine-West phalian Research Minister Svenja Schulze, IHK president Heinz Schmidt presented the award to Michael Szukala, Managing Director of G. Siempelkamp GmbH & Co. KG, and Prof. Ernst Peter Warnke from Siempelkamp Foundry. The next step: The new material, with the designation GJSF-SiNi 30-5, is currently being certified. This innovation can then go “on air” for the growing wind power market.

Wind turbines: energy around the clock 1991: The Act on the Scale of Electricity to the Grid (Stromeinspeisungsgesetz) initiates the boom in wind power in Germany. It obliges electricity network operators to purchase the electricity generated for a defined price. 1996: The first wind turbines in the megawatt class 1 to 1.5 MW are constructed. This is an occasion for Siempelkamp to acquire ground as a market leader in the field of large and complex cast components.
Rotor hub in the blasting shop
1999: Siempelkamp receives the first order in the field of wind turbines. A wind turbine manufacturer from Northern Germany orders the series production of rotor hubs (unit weight 8.5 t), trunnions (5.9 t), stators (3.1 t) and three blade adapters (6.45 t in total) for a 1.5 MW onshore wind turbine. With this customer, the Foundry demonstrates on the one hand its competence in ductile iron and on the other hand its ability to cope with large unit weights and large orders. 2000: The Renewable Energy Sources Act (EEG) comes into force in Germany. This serves as a motor for the expansion of renewable energy and as one of the most important instruments for environmental protection. 2001: Siempelkamp is ordered to produce cast components to be installed in a 4.5 MW onshore wind turbine. Siempelkamp casts trunnions, rotor hubs, stators and machine carriers. 2002: This is followed by an order for cast components for a 5 MW offshore wind turbine. 2002–2010: Siempelkamp steadily expands its competence in the series production of cast components in 1.5 - 7.5 MW turbines. This includes axle journals, rotor hubs, stator stars and machine carriers in onshore areas.
Rotor hub in the coating process
Areva component lower deck – bottom: view into lower deck during the ultrasonic testing for quality assurance
2011: An installed output power of approx. 27,000 MW is achieved with wind power. The proportion of offshore wind power amounts to less than 1% (approx. 200 MW) – onshore capacity dominates significantly. However, the German offshore wind market is growing: from 2013 to 2017, the Wind Energy Agency Bremen/Bremerhaven (WAB) estimates an installed output power of up to 4,500 MW.* 2011: A new milestone: start of series production of the previously mentioned cast components for 7.5 MW turbines, type A3 for Areva Wind – now also in offshore areas. Siempelkamp now produces in total 50% for onshore wind power and 50% for offshore wind power. The future of most multi-megawatt turbines clearly lies in offshore areas. We have recorded a good order intake that will guarantee high rates of utilization in the corresponding production areas over the next few years. A high net output ratio will be achieved within the group. All sectors of the company are involved in the production process: together with SNT (Siempelkamp Nuclear Technology), the machinery and plant engineering sector carries out the machining and coating; the foundry supports the casting product. “Raw casting plus machining plus open-sea-resistant coating equals delivery of ready-to-install components – wind turbine operators appreciate this overall competence,” says Stephan Kaiser. Until 2020: An offshore wind output power of approx. 41,000 MW will be installed in Europe and will cover a market volume of approx. 100 billion euros according to estimates from the WAB. The WAB industry report also estimates that Great Britain, Germany, the Netherlands, Spain, France, Belgium and Denmark will play the leading roles here. * WAB industry report, June 2011
