Rotor blades are heavily loaded and hard to reach. Even good quality blades deteriorate, suffering from harsh conditions. We are an independent service provider covering most of the services needed by turbine operators – inspection by optics and drones and image analysis, rope access inspections and special measurements, repairs and additional solutions increasing life span, production or decreasing noise. We work with high quality materials and each technician spends several weeks each year in special trainings. Our works are documented and provided to customers in easy to follow format. 3DWS’ parent companies have more than a decade’s experience in performing complex rope access works, difficult repairs and heavy installation tasks. We have experience with several blade manufacturers and perform repairs also in cold conditions and bearing productivity in mind.


Inspection and operation experience go hand in hand. We know where to look and what the possible root causes are. Inspection services contain damage assessments, installation supervision, shipment and take-over inspections, end-of-warranty and periodic inspections. Apart from general visual checks we do electric measurements, laser alignment, vibration and data analysis. Our findings are documented in an easy to comprehend format and visual material allows our clients to understand condition of their assets. At the moment we have experience with six turbine manufacturers and numerous models and modifications.
