HAMBURG – WINDEA Offshore, together with its partner WP Systems, has taken another step towards establishing the WINDEA Blade Service concept. Last week the operation of the working platform SYSTEM terra was successfully demonstrated at a Siemens SWT-3.6 offshore test turbine in the German district of Nordfriesland. The platform, which is used for maintenance and repair of rotor blades, has thus proven its functionality for the first time on an offshore wind turbine. About 30 representatives of different manufacturers as well as of some of the largest operators of offshore wind farms followed the invitation of WINDEA Offshore and took an active part in the demonstration.

The SYSTEM terra working platform developed for the rotor blade repair of onshore turbines has already been tested on the market for two years and is in continuous operation within the Buss Energy Group. The platform, which is completely protected from weather, enables technicians to carry out repairs around the entire rotor blade all year around. Work on the blade is performed at wind speeds of up to 12.5 m/s and 24/7 in a temperature- and humidity-controlled environment.

The SYSTEM terra working platform is already being modified to meet special offshore requirements and further developed into the SYSTEM aqua. The corrosion protection of the platform as well as the conditions of the offshore turbines play an important role. Among other things, the different dimensions of the foundation structures, the anchor points for rope attachments and also the bending of the rotor blades must be taken into account.

Ole Renner, CEO of WP Systems: “The personal exchange with manufacturers and operators has shown that we are absolutely on the right track. The feedback on the functionality and processing of our maintenance system was extremely positive. Once again it became clear to me how important such live demonstrations are”.

The on-site demonstration not only provided customers with a presentation of the WINDEA Blade Service concept and an inspection of the maintenance system. Rather, all participants were able to move along the offshore rotor blade at the platform themselves and thus gained an exclusive insight into the optimal working conditions. Martin Frederiksen, Integrity Specialist at Ørsted: „Safety and reliability are our top priorities. With this working platform we see the conditions fulfilled and could imagine using such a system for our maintenance and repair works.”
