D-TE™ – enabling operation through adverse conditions
Challenge
A 1.7 MW wind turbine with 50.2 m blades suffered damage when approximately 0.5 m of the pressure side shell at the tip was torn away by a lightning strike. The trailing edge was also separating as the blade rotated, putting the turbine at risk of downtime.
Solution
D-TE™ was used as a temporary repair to bond the trailing edge and close the opening caused by the liberated pressure side shell. This allowed the turbine to continue operating safely until weather conditions permitted a full repair.
Impact
The temporary intervention reduced downtime and enabled continuous turbine operation during a period when classical repair methods were not feasible, ensuring ongoing energy production and reliability.
