Wind Turbine (Blade) Inspection – While using drones for blade inspection we can maintain a safe distance for our operators and your equipment all while capturing high end still photos or 4k video.  This visual data can then be downloaded for immediate analysis and assessing blade damage for hairline cracks, near “end of warranty” protection for older wind turbines coming to end of life cycle, and insurance evidence collection.  Thus, reducing the need for lengthy shut downs (up to 5 hours per turbine), the need for workers to be repelling or heavy equipment in sometimes unforgiving terrain.

 

Wind Turbine Facts:

 

  • There are more than 800,000 blades currently spinning globally.
  • Commercial turbines can have tip speeds of over 200 miles per hour.
  • Inspection services can help automate data processing and analysis.
  • Drone or UAV inspections make operations and maintenance more efficient, cost-effective and safer.
  • Drone inspections can cover up to 8 to 10 turbines daily.
  • Blade damage is caused by leading edge erosion, moisture intrusion, freeze/thaw cycling and lightning.
  • Condition of the blades is essential to building a long-term strategy for maximizing blade life.
  • Maintaining blades are less likely to create unanticipated downtime and will generate more power consistently.
  • Leading edge erosion and deteriorating gel coats can significantly decrease the lifespan of a blade and cause performance losses.
  • Uncorrected erosion will lead to cracking, splitting of the blade tip, and blade separation.

Cost Benefits:

Drone based wind turbine inspections are up to 10 times faster than traditional methods.  By allowing for high resolution photo and video inspection competent operators collect data to be analyzed post flight.  All of this equates to time saved in the field, reduced crew sizes and increased safety and efficiency.

All of the data obtained during a field inspection is uploaded to an online portal allowing for instant sharing with executives, investors and qualified inspection personnel.  GPS assigned images allow for identification of each turbine allowing for quick decisions and deployment of repair crews in the event a critical failure is detected.
