Inspections & monitoring: Safeguarding performance and investment
Wind turbines are high-value assets exposed to constant mechanical stress and environmental extremes. Without proactive maintenance, small issues can escalate into major failures, leading to costly downtime and unplanned repairs.
These services are essential for maintaining structural integrity, ensuring safety, and keeping operations predictable and efficient. If these damages occur Everllence have the availability to perform up-tower repairs.
We are equipped to:
- Perform borescope inspections for internal component assessment
- Conduct Non-Destructive Testing (NDT) to detect hidden structural flaws with certified engineers.
- Select and install monitoring systems focused on critical components.

Machining services: Restoring precision, preventing downtime
Wind turbines face extreme mechanical loads, where even small damage can affect performance. Machining restores precision and extends component life.
We offer on-site and up-tower machining that avoids crane use and full disassembly, reducing time and costs while improving turbine reliability.
These services are essential for extending the life of high-value components and avoiding premature replacements.
Our up-tower machining restores OEM precision onsite for many turbine sizes. The process is completed in just days, ensuring a faster return to service and longer turbine life.
Our up-tower machining technology restores OEM tolerances on both the inner diameter and outer diameter, addressing wear that is normally inaccessible with standard tooling. By performing precision internal machining onsite, we eliminate the need for full drivetrain disassembly, delivering OEM-grade results in days and significantly extending component life.
Our onsite polishing process addresses the challenges of large diameters, segmented surfaces, and localized pitting, bringing yaw rings back to near-OEM condition. By improving surface quality and reducing friction, we stabilize yaw performance, extend slew bearing life, and reduce noise.
Our on-site bolt services ensure turbine joints remain secure, reliable, and capable of withstanding dynamic operational loads. By restoring correct clamping force and joint integrity, we prevent failures, extend the life of bolts and connected components, reduce downtime and maintenance costs.
Our on-site main bearing house and pocket repair restores worn or ovalized bearing seats to OEM tolerances using precision machining. The process ensures correct bearing alignment, eliminates play and misalignment, and prevents premature main bearing or drivetrain failure.

Welding repair: Structural recovery for wind turbines
Welding repair is a key service for restoring damaged or worn structural components in wind turbines. It enables recovery without full replacement, reducing downtime and preserving the integrity of critical systems.
Yaw and pitch gear teeth are restored using precision welding and re-machining, ensuring correct geometry, proper meshing, and smooth torque transmission. The service is flexible, allowing additional teeth to be repaired immediately if further wear is detected.
Bedplate repair restores cracks, deformations, or fatigue damage in a turbine’s main support frame using precision welding and machining. It can enhance the strength with adding support brackets. The service ensures correct alignment of drivetrain and bearing mounts, maintains structural integrity, and extends turbine operational life.
This service strengthens critical turbine structures by adding reinforcement elements, performing controlled welding, and applying stress-relieving treatment. It restores stiffness, corrects deformations, and ensures proper load distribution, extending component life and improving turbine reliability.
Service
Tailor-made uptower repair services
We provide specialized uptower repair services designed to solve complex and nonstandard challenges directly on the turbine, avoiding component removal and minimizing downtime.
Our key advantage is having an in-house team of engineers who can develop custom tools, fixtures, and procedures for unique tasks. Whether it’s precision machining, structural welding, or intricate mechanical repairs, we deliver solutions that are safe, efficient, and adapted to your turbine and site conditions.
Examples of Nonstandard Projects Delivered by Our Team:
- Machining a damaged hub edge while rotating
- Machining gearbox housing at torque arm casting
- Extraction of seized M64 bolt
- Thread repair in gearbox (M36)
- Repair of yaw drive flange
- Repair of locking device in mainframe
- Yaw drive flange repair using EFCO system
- Welding of internal tower bracket

Service
Workshop repairs
Not all repairs can be performed up-tower. For complex or heavy components, workshop-based repair ensures the highest standards of safety, quality, and performance.
Our global network of service stations provides comprehensive repair, refurbishment, and assembly services for wind turbine equipment such as: gearbox overhaul, generator rewinds and repair.
Service
Outstaffing engineers: Solving seasonal talent gaps
Seasonal peaks in wind farm maintenance often create urgent demand for qualified engineers, a challenge compounded by a global shortage of skilled wind energy professionals. Our Wind Engineers Outstaffing Service provides rapid access to pre-vetted experts who can be deployed on short notice to support your projects during high-demand periods.
