A 50 MW wind farm in South Asia has become the first to use a new repair method developed by Danish CNC Onsite and Dutch We4Ce. The technology makes it possible to replace loose bushings in the roots of turbine blades directly on site, reducing downtime and eliminating the need for external transport. This is stated by CNC Onsite in a press release.
The repair concept combines CNC Onsite's mobile precision drilling machine with We4Ce's patented Re-FIT method, where new bushings are attached using infusion technology. The solution makes it possible to rebuild damaged blade roots to almost new condition directly on the wind farm, without the need for dismantling and external transport.
Before the project started, the farm's technicians were trained in the Netherlands and Denmark in the use of We4Ce's patented “Re-FIT” method and CNC Onsite's specially developed precision machine. The repair method is offered as a licensed solution, enabling wind turbine operators to carry out major repairs with their own service teams.
After the training, the customer's service team in South Asia set up a temporary workshop directly at the wind farm, where they have carried out extensive repairs over several weeks under the supervision of CNC Onsite and We4Ce.
- Securing and now executing this first contract for our new method for replacing bushings directly at the wind farm was the result of solid engineering work with a focus on practical application, says Arnold Timmer, CEO of We4Ce
The method enables the customer to replace over 1,000 defective bushings and combines precision drilling with infusion technology, resulting in a nearly new component with a lifespan of up to 20 years. The work is carried out in temporary tents set up in the park, where the entire process – from drilling to final assembly – is carried out.
- We got the idea in early 2022 after an assignment with a customer in India and then spent three years developing and testing the solution.
CNC Onsite has developed special drills for this purpose that can handle the demanding work with fiberglass, while We4Ce ensures durable fastening with epoxy resin under vacuum.
Several projects are already in preparation, including in Brazil and the USA.
