Blades are the most expensive components of a wind-turbine system. They are subjected to extreme weather conditions and must withstand extreme loads. Blades and the reliability and cost of the energy the turbines produce are interconnected. Poor blade quality results in inefficiencies, breakdowns and, ultimately, less energy production. Therefore, specialist maintenance is vital to ensure optimal turbine conditions.

CAN Renewables offers specialist multibrand blade restoration and maintenance technical solutions and services. Although we are a new company, our blade credentials come from a blade technical team that has significant multiblade experience. We combine hi-tech unmanned aerial vehicle (UAV) technology, industry knowledge and access expertise techniques to service blades and prolong blade life to support your assets.

What we can do for you


Blade inspection and condition assessment

Regular inspections are vital for safe and sustainable operations with the priority of maintaining optimal asset performance. To maximise the cost-effectiveness of inspections, the quality and consistency of data need to be exceptional. CAN Renewables uses a specialist mix of blade repair technicians and hi-tech UAV technology to provide the highest-quality inspection programmes.

UAV inspection is the most cost-effective and efficient way of inspecting rotor blades, and CAN Renewables provides high-quality images, thermal imaging and video. When a defect is recorded, our specialist blade repair technicians can safely remedy the issue in real time, if required.

Blade inspection by blade technicians using access expertise ensures accuracy. A hands-on condition assessment assures accurate damage classification and provides the correct recommendation for repair, thus avoiding misidentification of defects. Inspection by blade technicians also enables further investigation using non-destructive or destructive test methods, such as taking core material moisture readings, crack investigation, testing the lightning protection system or drain hole clearance, thus mitigating the cost of further investigation.

Blade reconstruction and quality assurance

To maximise asset lifespan, asset integrity and return on investment, preventive maintenance and repairs are essential. With years of experience, our blade technical team can carry out blade repairs that prolong the lifespan and overall effectiveness of the asset. We can fix damage caused by leading-edge erosion, bond-line failure, moisture intrusion, freeze–thaw cycling, lightning damage and much more.

CAN Renewables offers solutions through a combination of preventive maintenance and repair. Our post-inspection approach is to work with equipment manufacturers and asset owners to assess damage categories in line with global industry standards; our extensive knowledge allows us to identify and repair all categories of damage from one to five. We also have the expertise to carry out nacelle repairs and uplifts; tower/monopile corrosion removal; and hub, spinner and cowling repairs.

Leading-edge protection

Leading-edge erosion, which affects almost all wind turbines, impairs their performance. Rain, hail, sand, dust and other airborne particulates adversely affect a blade’s aerodynamic efficiency, thereby reducing the turbine’s annual energy production and lifetime profitability. CAN Renewables has extensive experience of working with many leading-edge protection applications including tapes, paints, shells and custom-fit systems.
