In Germany, many wind power plants have currently to be renewed. On the one hand to increase productivity, on the other hand, due to the extreme wear and tear caused by their exposure. Existing plants are therefore partially being decommissioned in order to make space for new, state-of-the-art facilities.
In Germany, many wind power plants have currently to be renewed. On the one hand to increase productivity, on the other hand, due to the extreme wear and tear caused by their exposure.
Recently, one decommissioning project of this kind was successfully completed in the eastern Nordrhein-Westfalen region of Germany. At the beginning of 2020, a special construction company from northern Germany was charged with the decommissioning of three outdated wind power towers. In close collaboration with a renowned engineering office as well as with the (training) support of TYROLIT the project was strategically planned and implemented professionally.
From January 2020 to April 2020 a total of three concrete wind power towers were cut down from 110 m to 40 m. With the help of a specially constructed platform on the inside, the towers were first cut-off ring by ring, and were then removed with a crane. The wall thickness added up to 30 to 40 cm, whereas the bundled steel reinforcement was a major challenge of the project.
For this project, the team used two TYROLIT WSE1217 wall saws as well as the complementary WSL-Fast Cut wall saw blades with diameters ranging from 825 to 1,200 mm. Right from the start, the machines and tools proved to be the right choice for the task and the contractors literally worked at a very high and professional level.
The project even braved the adverse weather conditions: For safety reasons, works would partially be stopped due to winds peaking up to 10 m/s and more, and temperatures would drop under -2° C, inhibiting the water supply for the cutting tasks. Nevertheless, the project could be finished within the planned timeframe by the end of April without any major setbacks.
