MISTRAS helps to maximize the performance and uptime of wind turbines through a unique, integrated approach to turbine protection, encompassing monitoring, data services, inspections, maintenance, and access solutions.

MISTRAS’ wind turbine solutions help ensure that your assets operate safely and stay in top operating condition.

We perform field inspections and maintenance with cost-effective, quick, and safe access methods, and we also perform lab testing on newly fabricated and existing components to determine the root causes of damages. Our monitoring solutions enable asset integrity data to be gathered as soon as damages occur and instantaneously send it to a central repository, where operators have full access to their turbine integrity data on a fleetwide, sitewide, or individual blade basis.

MISTRAS' wind energy solutions are designed to help you make timely, informed maintenance decisions, to maximize the safety and uptime of your assets.

Wind Turbine Structural Health Monitoring (SHM) & Data Services

Our blade monitoring solutions utilize sensors placed on blades to detect cracking and corrosion promptly. AE technology measures defect growth on blade components, allowing our experts to analyze trends across sites and specific blades.

MISTRAS’ system for blade monitoring helps to identify:

  • High energy impacts
  • Lightning strikes
  • Ruptures to the blade skin or formation of perforations
  • Loss of bonding
  • Leading edge corrosion

Our customers have full transparency into the monitoring process, having direct access to a customized portal where they can view the current status of turbines and componentry in real-time. This portal allows decisions to be made quickly and effectively when damages are detected.

Wind Turbine Inspection and Composite Testing Services

MISTRAS’ wind turbine inspection services ensure that your assets operate safely and efficiently while remaining free of damages. We access all wind turbine components for field inspections with cost-effective, quick, and safe access methods, and we also perform lab testing on components.

Wind Turbine Blade Inspection Services

Blades are often the most at-risk component for damages on a wind turbine, and they can be challenging to inspect due to their size, at-height locations, and the sheer number of blades in a flight or site. MISTRAS helps maintain the safety and uptime for wind turbine blades through a variety of inspection services, including:

  • Ground-Based Photography – Our high-resolution telephoto lens captures images of turbines from the ground to properly assess necessary maintenance and risk.
  • Internal and External Non-Destructive Testing (NDT) Inspection: Ultrasonic Testing (UT), Visual Testing (VT), and Phased Array Ultrasonic Testing (PAUT)
  • Lightning Protection System Inspection & Testing
  • Root Cause Analysis
  • Digital Scanning of blades

Wind Turbine Maintenance and Mechanical Services

MISTRAS has the capabilities to provide maintenance and mechanical services, helping to ensure that damages discovered through inspections or monitoring are remedied as quickly as possible to minimize turbine downtime and reduce safety hazards.

We keep costs and downtime to a minimum by providing multi-disciplined technicians that perform both inspection and maintenance services, including:

  • Bolt Torque Testing and Tension
  • Bolt Replacement and Extraction
  • Bus Bar Repair and Replacement
  • Ladder Repair and  Replacement
  • Deck Replacement
  • Yaw Lip Seal Replacements
  • Blade Shroud Replacements
  • Cable Slack Repair
  • Bearing Seal Replacement
  • Cleaning or the tower, nacelle, and blades
    • Oil
    • Fire Remediation

Wind Turbine Blade Repair Services

Wind turbine blades are routinely subjected to extreme operating conditions. Manufacturing defects and the stress they are routinely subjected to during normal operations can combine to accelerate blade degradation. Other damages we inspect for and repair include:

  • Leading-Edge Erosion
  • Bond-Line Failures
  • Moisture Intrusion
  • Transportation
  • Lightning Damage
  • Fatigue Cracking
  • Dry Glass

MISTRAS’ trained rope access technicians provide inspection and maintenance services that keep wind turbine blades durable and reliable. Our goal is to keep your wind turbine blades spinning safely and efficiently.

Our blade repair services include:

  • Aerodynamic Profile Upgrades (VGs, Spoilers, Winglets)
  • Construction, Assembly, and Installation Support
  • Cleaning or repair of Cosmetic Damages
  • Installation of Leading Edge Protection Systems
  • Leading Edge Erosion
  • Lightning Strikes
  • Split Trailing Edge
  • Spoiler Removal and Installation

Wind Turbine Tower Repair Services

MISTRAS’ tower services ensure that wind turbine towers have solid structural integrity while also maintaining a clean and attractive appearance, including:

  • Cleaning
  • Coating/Painting and blasting
  • Weld Inspection
  • Caulking
  • Dent Removal

Wind Turbine Nacelle Repair Services

Wind turbine nacelles serve the important role of housing the generating components of wind turbines. MISTRAS’ nacelle services ensure that critical turbine componentry remains efficiently covered and protected, along with improving the physical appearance of the nacelle. Services include:

  • Cleaning
  • Composite Repairs
  • Weather Station Replacement/Repair

Wind Turbine Composite Lab Testing Services

MISTRAS helps you solve problems before they start with our destructive testing (DT), mechanical testing, and metallography services.

Our lab testing solutions support wind turbines throughout development, process certification, production, and potential damage analysis stages. Our Carbon Fiber Reinforced Plastic (CFRP) & Glass Fiber Reinforced Plastic (GFRP) testing centers help you to find the best possible materials for nacelles and blades and ensure their material properties before manufacturing.

In our state-of-the-art testing labs, we use multiple methods to test for and confirm material strength and durability, including but not limited to:
