Quality Control of a Pos Tensioned Concrete Tower for Wind Turbine Assembly

Abstract

Abstract More than 30 years ago, ENERCON created a unique technology patent in the form of gearless Wind Energy Converter technology. Ever since then, our engineers and specialists have been working continuously to further develop the products and manufacturing processes. We guarantee our customers maximum agility and excellent solutions which make good economic sense and comply with market requirements. Innovations are fundamental to success here. We want to be the first to establish new ideas on the market and new standards in the industry. The expertise of our employees and their interdisciplinary working partnerships form are the essence of our technological excellence. Every day we work to live up to our claim to perform as technology leader. We are leading the way in developing new technologies and taking an active and responsible role in shaping the future of energy generation and supply from renewables. For that we aim to develop and produce the highest-quality wind energy converter on the market. We do not define ourselves primarily in terms of the purchase price, but instead offer turbines with the lowest running costs per unit generated. Content and well-qualified employees are essential for long-term success. That is why we make huge investments in training and advanced training and measures to promote healthy workplaces. The successful further development of our high-tech products relies on us working together. Hybrid towers for ENERCON wind energy converters comprise individual precast concrete elements and steel sections that form the top end of the tower. Concrete segments with large diameters are produced in two or three shells so that they can also be transported to locations which are complex to reach. After all segments and sections have been assembled, the bottom steel section, the concrete segments and the foundation are joined together and tensioned to form one unit by means of prestressing tendons.
