Every technical system requires regular maintenance to ensure a long service life. For systems as complex as a wind turbine, regular inspection and maintenance are of great importance.

The tower is the largest and heaviest element of a wind turbine, they are subject to extreme stresses and environmental influences. Refurbishing is necessary because the already existing corrosion needs to be removed and corrosion protection is applied.

While the generation and use of offshore wind energy is relatively new in Germany, the onshore generation of wind power started three decades ago.
