    In the next few years, most of the wind turbines installed in Spain will be 15 years old since their installation and commissioning.

    The need for manufacturers, maintainers, developers and owners of wind farms to increase the life of wind turbines has led to the implementation of life extension plans for wind power plants in recent years.

    SCI, Control & Inspection echoes this concern and offers to the market new inspection systems for the determination of structural defects in wind turbines.

    In particular, it has designed and put into operation an automatic system of inspection ultrasonic inspection of the welds of the wind towers in service.

    Wind turbine weld inspection

    The welding inspection of the wind towers is performed using a magnetic trolley, developed by the R&D department, with access from the outside of the tower remotely controlled from the ground by an SCI operator.

    Applications of automatic ultrasonic equipment:

    • Maintenance and monitoring of wind towers.
    • Inspection of towers in wind farm life extension plans.
    • Detection of cracks and internal defects in welds without affecting the paint.
    • Dimension of the detected defects in length and depth.
    • Close-up visual inspection of surface structural defects (dents, defects caused by blade impact, lightning strikes, etc.).

    Advantages of weld inspection on wind towers

    • Avoid the use of elevating platforms and rope climbing methods.
    • Data recording, verification and consultation at any time during the life of the machine.
    • Monitoring of weld condition and progress of defects detected in previous inspections.
    • Real-time display of correct data acquisition.
    • Inspection of 100% of the weld volume.
    • Possibility of weld inspection with the machine in service.
