Towers for wind turbines comprised of double-wall elements

The energy transition requires electricity to be generated from renewable sources such as wind power. In the foreseeable future, there will be a scarcity of potential high-yield onshore generation sites, which is why a growing number of wind turbines will have to be erected in lower-yield areas. To achieve acceptable energy yields in these regions, wind turbines that are usually erected as tower structures must have large hub heights. Thus, the associated increased dynamic loading makes fatigue a key design criterion.

Hybrid construction methods have become the state of the art for erecting...
