Composite / Blade Repair

From inspections to repairs, we cover it. Turbine installations have increased dramatically in the last decade and now blade repair is in full force. We offer blade inspections via several methods to help identify and classify the type of repair necessary. We work directly with blade manufacturers and follow their strict guidelines for repairs to ensure they are strong, reliable and suitable for appropriate climatic conditions. Our goal is to repair all damage using whatever method is most cost effective for our client and to satisfy local and site guidelines for safety.

Our composite repair services:

  • Blades
  • Leading Edge Tape installation
  • Nacelle
  • Hub
  • Damaged components during construction

Wind farm owners and operators rely on accurate and detailed data collection, processing and QA/QC to ensure their study is completed correctly to satisfy all permitting requirements. Audio is only half of the solution to precise noise studies. Having in depth expertise in complete wind resource assessments and hundreds of met tower installations globally, including power curve verification (IEC 61400-12); we excel in both audio and met data collection.

We treat your assets like our assets. Great maintenance is not just about replacing parts when they are damaged. It’s performing root cause analysis during troubleshooting and implementing long term solutions to problems wherever possible. Having an in-house team of engineers who laterally support our O&M team has led to increased production from our sites. Both teams, work together and exchange information from the field to the office to make improvements, not only to procedures and tooling, but for components and design improvements that can significantly improve reliability of equipment.

We pride ourselves in a positive team attitude and when faced with new issues or troubleshooting, our technicians have a large network of knowledge and resources they can rely on.

Our O&M services are:
