ADVANTAGES OF ROPE ACCESS IN ROTOR BLADE INSPECTION
The experience in rope access combined with expertise on wind turbines is the main advantage of the services that can be provided by GRwind professionals to the energy industry.
The 'tap test' is very important to perform a correct evaluation of damage extension and magnitude and to prevent 'hidden' damages.
Rope access expertise provides excellence on technical results besides contributes to save time and money in the energy industry, finally it is environment friendly.
WORKS PERFORMED • Hidden damage detection in a rotor blade
• Lightning protection pystem (LPS) evaluation
• Drainage system assessment and cleaning
Very often lightning receptors in blades are not working. Defective LPS combined with clogging in drain system can lead to serious structural damages, especially in blade tips. They can explode (image 1) due to heating and water accumulated inside when a lightning strike hits the blade.
Rope access provides a fast, safe and high quality solution for the wind industry once that is not dependent on the mobilisation of heavy equipment and large teams moreover it can be used in more restrictive weather conditions.
BLADE INSPECTION
Nowadays the importance of rotor blades periodic inspection is recognised due to the prevention of severe damages through early detection of evidences. Thus, expensive costs can be avoided and the productivity of the turbines not compromised with downtime.
It’s widely accepted that the aerodynamic blade profile has influence on turbine productivity therefore operations, as inspection, maintenance and early repair, should be performed in situ, by expert professionals and as soon as possible.
