The Space Frame Tower (SFT) is a unique wind turbine foundation concept combining excellent strength and fatigue properties with flexible and cost-effective fabrication. Suitable for water depths from 20 to 60 meters.
The triangular design with parallel legs and constant leg diameter enables efficient fabrication of components with equal lengths and angles - only member thickness is varied dependent on water depth and tubine type.
Fatigue is a critical issue for all offshore steel structures, and wind turbine foundations in particular. The standard nodes, which can be mass-produced by hot-forming and automatic welding, have excellent properties with regards to stress concentrations and fatigue.
Identical geometrical interfaces between all components makes assembly simple and efficient.
