E.ON has used its new anti-corrosion technology to protect wind farm foundations for the first time.

The company announced it is protecting all 60 steel monopiles of the Arkona facility in the Baltic Sea with the Thermal Spray Aluminium (TSA) coating to prevent damage from the harsh operating environment.

The firm says during the 25-year operating period, metal corrosion will be significantly reduced and deposits into the sea of several hundred tonnes will be avoided.

During the coating process, a robot sprays a 350-micrometre thick layer of molten aluminum onto the foundations, before sealing it with resin.

The process is carried out under strict environmental protection standards and is said to be cheaper and tougher than conventional corrosion protection.
