    Foundation design even in a day. One of the main hurdles in developing large wind parks is timetable. Typically, it will take 4 to 8 weeks to get a foundation design from an engineering company or a structural designer. And if there are different soil types in the area chosen for your wind park, more weeks are lost doing additional designs.

    were of sufficient magnitude to cause vibrations in the foundations of up to 0.1 mm. Using seismic accelerometers, the decay of these vibrations after shutdown was recorded from which the damping and natural frequency of the foundations were determined. Mill forces were also measured. The SAG mill force frequency spectra showed distinct peaks
