  • Such foundation structures are usually gravity foundations or foundations of steel structures such as tripods or post or post built. As a rule, such foundation structures are designed post-like to the turbine unit. In rivers, the foundation is also tied offshore.
  • Seawater is known to be aggressive and causes a strong aging process of the structures.

This can be done by disassembling the single sheet from the remainder of the rotor and treating its surface, for example by grinding. Such a process is complex and therefore expensive. It also does not always lead to the desired result, because in the mentioned treatment, the geometry of the single sheet can be adversely affected.
