Germany: Victoria Mathias Installs First Foundations at Nordsee Ost

The first foundations at the Nordsee Ost offshore wind farm have been installed.

The main crane of the Victoria Mathias lifts the 550-tonne steel foundations into the water. Whith roughly 40- to 50-metre-long steel piles the foundations are fixed into the seafloor. Then a hydraulic hammer knocks them 40 metres into the earth.

After that the foundations are aligned horizontally before being finally anchored in place with special concrete.
