Leading Edge Restoration
Wind turbine blades are constantly exposed to the elements of nature, resulting in wear of leading edge, exposing the fiberglass beneath, and reduces wind turbine efficiency as aerodynamic properties of the blade is affected. This can lead to expensive repairs if not treated early.
- The robotic arm is initially fitted with a surface sanding toolset which carefully prepares the leading edge.
- Another toolset is then used for surface cleaning and decontamination.
- The robotic arm is finally fitted with a painting toolset that applies a new topcoat onto the leading edge.
Oxidation between the different elements of the Lightning Protection System can occur and often requires blade engineers to remove a section of the blade to rectify the problem at a great repair cost and extended turbine downtime. Bladecare offers an alternative method, that not only leaves the blade intact but also reduces downtime significantly.
- The robotic arm is fitted with a purpose-built toolset for restoring faulty receptors.
- By inducing high current into the circuit, the oxidation can be removed, and continuity restored.
- The resistance of the path from the faulty receptors to blade root or ground is measured to confirm the successful restoration process.
Ice accumulating on wind turbines not only leads to degraded performance of the wind turbine but also causes rotor imbalance that affects mechanical parts of the turbine, such as gearbox and bearings. Potential ice throws also pose a serious safety hazard.
- The robotic arm is initially fitted with a blade cleaning toolset and cleans the complete blade.
- A brush system in combination with a biodegradable cleaning agent allows for environmentally friendly and efficient removal of contaminants
- Another toolset is then used for surface preparation and decontamination.
- The robotic arm is finally fitted with a painting toolset that applies a new topcoat followed by a hydrophobic layer onto the blade.
