Turbines cannot settle or tilt in any way or they will first lose efficiency. After that, the equipment will begin to break. The permafrost layer of the earth is constantly fluctuating in depth and distance to the surface. This not only affects the tower itself, but also the construction of the tower. The cranes [...]
