Wind blade repair: Top difficulties we need to carefully identify

Wind blade repair has also become an urgent and popular need, in the context of increasing wind power projects. However, unlike other repair jobs, repairing wind turbine blades is a job performed at height and has many specialized difficulties. So what are the difficulties? Let's find out in the article below.

What are the most common blade repair difficulties nowadays?

It can be said that the wind power industry is booming like never before. Large and bulky wind turbine structures offer great value but are also the cause of many other problems. In addition to the shipping and assembly as we are used to seeing, wind blade repair also faces a lot of challenges.

Blade repair challenge #1: Danger of life for workers when working at height

Except for major damage that cannot be done at height and damage that occurs during transportation and assembly, most of the wind turbine repair work is done at height. Repairmen will climb onto turbine blades and controls or where damage has occurred to perform repairs.


Wind turbines that are several hundred meters tall are not safe places to work. Moreover, when performing overhead blade repair, factors such as wind, sudden rain or unsafe tools are also causes of occupational accidents. Another obvious cause is the approach. Massive turbine systems require a consistent and safe approach to facilitate repair.

Blade repair challenge #2: Shortage of human resources to accomplish the job 

As mentioned above, wind turbine repair is a very dangerous job, requiring the operator to be in good health and able to work at height. Moreover, the overhead repair requires the technician's skill to be good to ensure accuracy and speed. Therefore, despite the increasing repair demand, qualified technicians are very few, not enough to meet the market demand.


Currently, technicians qualified to practice need to undergo intensive training and obtain regulatory certifications in wind turbine repair. Failure to guarantee the number of technicians can have greater consequences when wind turbine systems are not restored in time. Along with that, unqualified technicians also do not help project owners solve existing problems, and even cost more to fix.


Blade repair challenge #3: Many hidden problems which are hard to detect

Large and tall wind turbine structures are especially difficult to detect in a timely manner. Major damage such as broken or warped propellers can be seen with the naked eye. But most failures occur in the control box or on the propeller, which is difficult to assess. This work of blade repair will require a team of experienced professionals and advanced tools to check the system to have a plan to repair the blower if a problem is detected.


However, hiring maintenance and repair services is not a regular option. And the project owner does not always detect the problem in time to proactively call the wind turbine repair team. Damage to the propeller such as rust, corrosion of the blade joints, if not repaired, can quickly cause great losses such as replacing the propeller.


The above are the 3 biggest challenges that project owners, as well as wind turbine contractors, face when repairing wind turbine blades. However, along with the constantly increasing market demand, the wind blade repair and maintenance market is constantly being improved in terms of plans, approaches and technicians. This is particularly important for the wind power industry as it significantly reduces costs, increases system efficiency as well as ensures safety for project participants.
