Wind turbine blade repair

Who is wind turbine blade repair & maintenance?

Started by blade pioneers, we have grown into a complete repair, maintenance and inspection services company for utility-scale wind turbine blades. Our certified technicians are committed to professionalism, safety, quality and exceptional customer service with a focus on minimizing downtime and maximizing output of the wind asset.

How to repair a wind turbine blade?

Still, for the wind turbine blades, where aerodynamic properties are of critical importance, flush repair is the most common structural repair technique. Structural flush repair is realized by forming a joint between prepared repair area and the repair patch, which should fit exactly the area prepared for repair.

How often do wind turbine blades need to be repaired?

Typically, wind turbine blades require repair after each 2–5 years , thus, creating the permanent factor of costs increase for wind energy industry. The wind operations and maintenance (O&M) market is expected to reach $27.4 billion by 2025 globally, with the compound annual growth rate of 8% .

How much does it cost to repair a wind turbine blade?

If a crane is required to repair or replace a blade, the cost can run up to $350,000 per week. An average blade repair can cost up to $30,000, and a new blade costs, on average, about $200,000 . The wind turbines built and established at the beginning of century, becoming old now.

Why do wind turbine blades fail?

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

What is the on-site repair of wind turbines?

The on-site repair of wind turbines is carried out under difficult weather conditions, on ropes, and under time pressure, and is limited to a rather narrow weather and time window . As shown in section 5.2, the repair quality is very sensitive to the possible defects in the adhesives.
