Wind turbine blade repair and monitoring network
We4Ce and CEWA Plus establish regional blade repair services and introduce GapMaster Intelligence for condition-based monitoring across Asian wind energy markets.

We4Ce, a Dutch authority in rotor blade technology, and CEWA Plus, a Thai renewable energy developer, have signed a Memorandum of Understanding (MOU) to establish a regional service network for on-site blade root bushing remanufacturing. Launching in April 2026, the initiative will deploy a high-precision, downtower repair methodology across 12 Asian markets, including India, Sri Lanka, Thailand, and Vietnam.
Redefining Structural Maintenance with Re-FIT
The partnership integrates We4Ce’s proprietary "Re-FIT" methodology with mobile machining hardware from Danish partner CNC Onsite. This solution addresses a critical failure point in wind turbines: the structural connection between the blade root and the hub.
- The Challenge: In many blades, polyester shrinkage or uneven distribution can lead to microcracks in the bushing's interface layer. Left unaddressed, these cracks can cause the bushings to loosen, risking catastrophic blade failure.
- The On-Site Solution: Traditionally, repairing loose bushings required expensive blade replacement or off-site transport. The Re-FIT process allows for downtower remanufacturing, where blades are lowered to a controlled field environment for precision-drilling and vacuum infusion of a high-strength replacement layer.
- Economic & Environmental Impact: This on-site approach reduces repair costs by up to 60%, significantly minimizes downtime, and lowers CO2 emissions by eliminating heavy logistics and blade waste.
- Proactive Monitoring: GapMaster Intelligence
A key component of the MOU is the launch of "GapMaster Intelligence," a condition-based monitoring system developed by CEWA Plus. This system shifts maintenance from reactive to proactive:
- Laser Precision: The system uses high-precision laser scanning to continuously monitor the bond between the bushing and the blade root.
- Real-Time Alerts: If a gap is detected or begins to expand, the system triggers an automated alert via the plant's SCADA system.
- Asset Life Extension: By providing real-time structural health data, operators can maintain a "like-new" standard for blades throughout their entire service life.
Regional Scaling and Technology Transfer
Building on a successful 2025 pilot in Thailand—where 22 blades were restored in-situ—CEWA Plus is establishing a regional service hub to manage a multi-gigawatt pipeline of repairs.

- Technology Licensing: Delivered under a licensing model, this partnership allows wind park operators to perform major remanufacturing independently using their own service teams.
- Specialized Training: Technical teams from Asia are scheduled for training in Denmark and the Netherlands in late spring 2026. The program focuses on operating custom machining hardware and mastering the patented vacuum infusion process.
- Future Outlook: While currently focused on onshore assets, offshore solutions are already in development to bring this sustainable maintenance model to the maritime wind sector.
