The Deutsche Windtechnik Inspection Physique conducts varied technical inspections all through wind generators’ life cycles. These embody commissioning, guarantee, periodic, and condition-oriented inspections.
The multi-stage drone system, CU-RE, developed by the Deutsche Windtechnik Inspection Physique for inspecting rotor blades and lightning safety programs, has handed validation. TÜV NORD performed its first conformity evaluation, affirming the drone’s functionality to evaluate the technical situation of rotor blades and lightning safety performance. This permits for the analysis of stability and public security dangers, making CU-RE appropriate for periodic inspections.
Throughout an order-specific danger evaluation performed within the early phases, the inspection physique assesses whether or not drone expertise or rope entry is extra appropriate for the inspection goal. If drone expertise is deemed preferable, the totally validated three-stage CU-RE mannequin is employed. This mannequin adheres to stringent inspection necessities outlined by the EASA, generally used within the aviation business. The primary stage entails a complete visible inspection utilizing automated drone flight, scanning 100% of the rotor blade’s outer floor for seen injury or irregularities. The second stage might embody selective, manually guided drone expertise if obligatory. For extra in depth inspections, specialised drone or rope entry choices could also be utilized within the third stage.
“The validation by TÜV NORD confirms that the drone expertise utilized by the Deutsche Windtechnik Inspection Physique is appropriate for finishing up a spread of vital inspections akin to periodic and condition-oriented inspections. In
view of the present scarcity of expert employees and the quickly rising turbine stock, this is superb information for your entire business as a result of drones will considerably cut back the quantity of labor required in addition to downtimes. In Germany this can shut an vital hole as a result of legislators haven’t but adopted any necessary necessities for the usage of drones within the wind power business,“ stated Matthias Brandt, Director of Deutsche Windtechnik.
Michael Lange, Head of the ISO 17029 Conformity Evaluation Physique for Wind Vitality at TÜV NORD, added, “The inspection process was validated in opposition to our new TÜV NORD customary. This customary defines standards and
inspection factors that permit drone inspection procedures to be evaluated. For the validation, the reliability of the processes was evaluated utilizing documentation assessments. Along with specs for the gear used,
this additionally contains specs for flying and high quality assurance. The profitable validation solely applies to the drone expertise utilized by Deutsche Windtechnik. Different drone programs available on the market can be evaluated utilizing the
new customary. By introducing our new customary TN-P-V01-001, TÜV NORD has responded to the growing use of drones and created a uniform evaluation for the security of wind generators.”
