After an EF-3 tornado struck Texas in Spring 2022, Barnhart responded to a customer's call to repair four damaged wind turbines. The violent tornado caused damage to every blade, control cabinets were sucked out of the hub and nacelle, and repairs were intensive. Once replacement components were secured, Barnhart mobilized to dismantle and rebuild the affected turbines.
Barnhart utilized engineered rigging to remove the damaged rotors and safely lower them to the ground. Blade debris was removed from the hub and recycled.
Barnhart rebuilt hub pitch and hydraulic systems, installed replacement bearings, cabinets and fiberglass, and readied components for reassembly.
Barnhart completed the rebuild of all four towers over the course of 15,000 man-hours in 2024. Towers were returned to service as they were completed and are once again producing power.
