Wind Energy – Foundation Drilling
The Herrenknecht Offshore Foundation Drilling is currently the largest offshore drilling rig and is successfully used by DEME Offshore to install monopile foundations at Saint Nazaire, France.
A total of 73 monopiles with a diameter of 7,700 mm have to be excavated at depths between 6 and 24 m.
This new machine offers significant ecological and economic advantages over traditional methods.
The Saint Nazaire offshore wind farm is the first offshore wind farm in France.
It is also the first offshore wind farm in the world where rock drilling for XL monopiles is one of the essential installation techniques.
