The turbine manufacturer signed the MoU to enable the development of a 139-metre-high tower specifically designed for Alstom's ECO 122 onshore wind turbines.
Max Boegl has developed a hybrid concept for towers, made of concrete in the lower section and of steel in the upper section. This design will be adapted for Alstom's ECO122 as a solution for low wind sites, especially in Germany and other parts of northern and eastern Europe.
The MoU will also cover a technology partnership for a new installation method. The concrete section of the tower will be pre-cast at the Max Boegl factory to ensure the maximum quality in the process.
In addition, a new approach has been developed for the tower and wind turbine erection with the use of self-climbing tower cranes for construction on sites with very limited space.
"We want to combine a wind turbine with a big rotor diameter of 122 metres with a high tower of 139 metres to have an effective solution for Germany, especially for forest areas with the use of our tower crane to reduce the required area," said Max Boeg Wind CEO Stefan Bögl.
"Our hybrid tower is a combined solution of concrete and steel. We believe this is the best solution for the future."
Most of the available new wind sites in Germany are low wind zones. In these areas, the height of the tower makes a difference because the higher the tower, the more wind is available as higher winds can be captured.
This opportunity applies mainly to wind turbines specifically suited to low winds, such as Alstom's ECO 122, which have big rotors.
