Timely repairs on the spot retain functionality for maximum wind efficiency.

Despite a design for an operational period of 2 decades, the robustly constructed rotor blades are very often characterized by yield minimising damage after some time.

With specially designed platforms we gain safe access to the damaged areas needing repair on the rotor blades. This applies for all manufacturers-types and facility sizes.

The fitness programme for high-yielding blades.

Here L&L offers perfect repair measures for the elimination of cracks and flaws with special techniques and materials. Repair of the tip mechanics and restoration of the lightning protection are also a part of the repair services on site.

Erosion and operation related abrasion on the rotor blade leading edges are the typical damage patterns in survey reports. As an effective long-term protection, an erosion and abrasion preventing plastic protective film is applied to the heavily burdened blade leading edges. This extremely durable erosion protection foil protects the rotor blade leading edges for far beyond 10 years.

*The professional repair services are certified and executed in accordance with the strict guidelines of Germanischen Lloyd.
