D-TE™ – restoring blade integrity for higher availability
Challenge
A 5 MW wind turbine with 59.5 m blades, commissioned in 2013, was being curtailed due to blade overload. An open trailing edge in the mid-span region increased structural risk and limited safe operation, reducing turbine availability.
Solution
Our team completed a root cause analysis and applied D-TE™ to 90 blades to eliminate the open trailing edge and restore blade integrity. The solution was designed to remove the overload risk and enable normal turbine operation without requiring structural repair.
Impact
The intervention increased turbine availability and eliminated the risk of further asset damage. The certification body confirmed that the D-TE™ solution did not affect the blade’s load-carrying capability, providing assurance of long-term operational safety.
