Denmark based offshore wind developer, DONG
Energy, has chosen a trio of 200HD Vibrodrivers, made by French pile
driving technology manufacturer, PTC, as an alternative solution to
hydraulic hammers for its Anholt offshore windfarm to reduce noise
emissions.
DONG Energy is in the process of building the Anholt offshore
windfarm which is situated between Grenaa and the island of Anholt, off
the east coast of Denmark.
The building of the Anholt foundations required the driving of large, heavy monopoles, which were driven into the sea bed with hydraulic hammers using impact driving technology. Impact pile driving creates a high under water noise level, creating strong sound waves which endanger the surrounding marine life. So DONG Energy chose PTC's Vibrodrivers as an alternative to reduce the noise emissions under water.
PTC’s Vibrodrivers drive the pile in accordance with the latest German regulations in noise emissions under water which stipulates a maximum of 160dB at 750m. The PTC technology offers significant environmental benefits for offshore windfarm foundations including low noise emissions, precise pile positioning, easier and safer pile handling and underwater pile driving up to 100m.
Once completed, Anholt windfarm will be Denmark’s largest, with an overall capacity of 400MW which will cover 4% of the country’s total power consumption.
