How it works
Our approach is based on a thorough Last Minute Risk Analysis (LMRA) prior to each intervention, as well as a comprehensive set of over 200 technical inspection points that can lead to recommendations. These include acoustic resonance testing of connections, visual inspections of electrical components and rigorous verification of maintenance and safety standards. This method aims to predict the immediate and future performance of a wide range of wind turbine models.
