Alstom has signed a memorandum of understanding (MOU) with Germany-based wind energy planning and construction services provider Max Bogl Wind AG for the design and construction of a 139-meter hybrid tower for its ECO 122 onshore wind turbines.
The company says the MOU will also cover a technology partnership for a new installation method. The concrete section of the tower will be pre-cast in the Max Bogl factory to ensure 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 limited space.
Max Bogl has developed a hybrid concept for towers made of concrete in the lower section and steel in the upper section. This design will be adapted for Alstom's ECO122 machine, which is suited for low-winds site, particularly in Germany and Northern and Eastern Europe.
