Works with rope access

Offshore and onshore wind farms

WIND PARKS

Gridinta can provide specialists to perform work of any complexity, on both onshore and offshore wind farms. All technicians have permissions and International certificates for rope access work.

  The scope of works our rope access technicians have performed on various wind parks:
Vortex replacement works on turbines (SN129)
SN154 Equipotential Bonding – exchange of screws on all blades and reactive repair of loose or movable bonding rails according to repair instruction
LPS Measurement & Blade Interior Inspection, checking the lightning protection system of rotor blades
Visual inspection of rotor blades, an inspection of root flange laminate cracks

Wind generator inspection

Preoperational and regular operational inspection of wind generator elements includes a complex of operations. Using a system of different inspection methods and analysis ensures the earliest possible detection of any departure from the norm and different defects. This allows avoiding potential damage and shortening the idle time of the wind power turbine.

  Inspection methods:
Visual testing (VT) including visual inspection of rotor blades
Dye penetrant testing (PT)
Ultrasonic testing: Manual UT and UTM method; Automatic P-scan and T-scan method
Thermovision

Inspection / repair of rotor blades / towers

Gridinta provides inspection and repair services for rotor blades and wind towers. Our specialists have developed a technology for the application of the thermovision method for detecting defects in the structure of wind turbine blades. Technicians compile inspection protocol depending on the scope and complexity of the object.

  The report includes:
Schematic drawing of the blade with the location of detected defects specified
Detailed description of individual defects with the dimensions (level) of faults specified
Detailed description of the types of faults and the nature of detected defects
Photo and video material
Analysis of defects and recommendations for their elimination

Gridinta provides rotor blade repair and other services for wind towers.

By analyzing the results of the blade inspection report, the specialists of our company prepare recommendations and develop a technology for the repair of the detected defects. When developing the repair technology, account must be given to the kind and nature of the faults as well as the acceptability of the defects.

Blade repair is carried out by the specialists who have completed special training for working with composite materials (fiberglass and epoxy resin). To accelerate the repair process as wel as to achieve the maximum quality of the blade repair, the UV curing system is applied. After completing repair works for the structure, its paint coat is necessarily restored.
