Increasing the reliability of rotor blades
In the last two decades, the length of the rotor blades for offshore wind turbines has increased significantly. Where we started with blade lengths ranging between 30 and 40 metres, we are now reaching 110-120 metres in length per blade, and this may go up towards an impressive 150 metres in the future. Despite efforts to improve control over the manufacturing process, defects still occur during production and operation that may lead to blade failures. This can significantly affect the wind farm's power output and repair costs. Therefore, the sector is looking for more reliable blades that can cope with the immense forces. Reason for David de Jager to visit Michiel Hagenbeek and Wim Castricum of TNO to dive into the world of rotor blades. Michiel runs blade models in a digital twin; Wim crawls inside actual blades to apply the sensors.
