ISQ bets on digital inspection in wind blade repair

The wind generation sector is one of the segments of the industry that has experienced rapid global growth. Studies point to the existence of more than 300,000 wind turbines installed worldwide. The blades of wind turbines are elements of sophisticated design, which have complex curves. Based on structures of several layers of varying thickness, they are constructed with materials composed of layers of fibers and artificial resins, sometimes with reinforcement in wood. These elements are designed to work for several years. However, problems can arise as the blades suffer wear, impacts of particles dragged by the wind and strong tension and tortions, which can cause a complex series of defects, variable according to the type of blade design, its model and even serial number. That's why the wind industry needs technical reports that can accurately detect, analyze, diagnose problems and issue concise recommendations. Data that can actually establish a preventive maintenance scheme. Digital inspection has revolutionized and simplified the repair of wind blades, with advantages from the point of view of safety and quality of the data obtained. ISQ operates at the level of the inspection of blades in the factory, a service aimed at park operators, inspecting the blades manufactured or that are in the process of being manufactured and presenting the results of the analysis carried out with indication of the condition status of the same. It also operates in the inspection of blades for manufacturers and owners of parks, a service based on the analysis of photos of the blades of wind turbines obtained from drones. These images are used to identify defects, categorize the degree of severity of the damage as well as the repair period. In addition to wind power, ISQ has know-how and provides services in the areas of photovoltaics, water energy and energy efficiency, adding to its pioneering presence in the European Project Naturalhy, in preparation for the hydrogen economy using the existing natural gas system as a catalyst. "At the level of the Hydrogen line, ISQ's skills go through the know-how in terms of sustainability, materials and reliability, sensorization and algorithms, risk and safety assessment, training and qualifications and quality assurance and control," says Pedro Matias.
