Leading edge erosion is a phenomenon effecting more and more wind turbine blades every year. With the wind industries relentless developments increasing both blade length and average tip speeds this once manageable but frustrating issue has developed into an epidemic which is already affecting turbine efficiency, blade integrity and therefore your revenue.
Both the currently available erosion products and repair processes have shown to be difficult to apply in the field and do not last more than a few years in real world conditions. A totally different and innovative approach is required if blade leading edges are ever going to be maintenance free.
advantEDGE is this ground breaking, solution to the growing global problem of Leading Edge Erosion (LEE), which combines both repair and protection. If you own or operate wind turbines, make blades, manufacture wind turbines, or provide blade repair services, advantEDGE is the 21st century solution you’ve been looking for.
advantEDGE recovers the lost efficiency from the Leading Edge (LE) aerodynamics to regain the valuable lost yield for up to 20 years* offshore. It also minimises downtime from reduced visits for future repairs making advantEDGE revolutionary to the wind industry.
The advantEDGE system comprises of two principle innovations. Firstly a simplified repair process that is far less weather dependant than current methods. Secondly, a series of advantEDGE LE erosion shield modules will be manufactured for your blades and available globally. Our erosion shields are available as partially recessed or leading edge covers. Each series of erosion shields will be installed either using a high precision, highly automated robotic arm machining system or a manual machining system which can be installed via rope access.
How does it work?
Rapidly, efficiently and cost effectively!
If using the automated system an access platform is used by field technicians to secure a robotic arm to the blade with a specialist mounting attachment, which can be adapted to varying surface geometries/blades. Automated high precision machining of the eroded LE material takes approximately 30 minutes to create a very shallow recess.
The manual machining system is deployed by rope access to also create a series of very shallow recesses on the leading edge.
This recess will mirror a bespoke prefabricated erosion shield for this sector, typically under 2mm thick, which is then bonded into place; no LEP (Leading Edge Protection) coating is required because the modules themselves are highly durable. This has been proved in extensive rain erosion and environmental tests in a test mythologies approved by DNV-GL.
Why choose advantEDGE?
Substantial cost reduction!
In preference to repeatedly repairing and protecting the LE of all your blades the advantEDGE system is a much more efficient O&M strategy because it rejuvenates each LE for up to 20 years*.
One of the key benefits of the advantEDGE system is the substantial reduction in O&M costs. advantEDGE lowers blade related O&M LCOE by up to 70%, and minimises downtime while increasing yield. It also extends the useful life of the blades to optimise ROI and prevents damage to the structural integrity of the blade, which could result from increasing numbers of composite patch repairs. This unique combined ‘repair and protection’ method will significantly improve the environmental impact of O&M both onshore and offshore.
advantEDGE is available globally to OEMs, Utilities, Owners, Operators and independent service providers. Industry leading partnerships are currently being sort to expand the advantEDGE offerings. Call +44(0) 1698 831111 today to learn how to protect your wind turbine assets more cost effectively.
*at least 20 year statement is the average predicted life calculated by industry experts. Actual results will depend on factors including tip speed and annual rainfall. Field results may end up either higher or lower than this value but erosion trials have been shown to last in the region of 10 time longer than conventional blade material.
