According to Lloyd’s Register, the collaboration will provide a critical approach on how to control noise transmission at sea, help safeguard marine life and ensure sustainable project delivery.
When fully operational, the 400 MW Horns Rev 3 wind farm, situated off the west coast of Denmark, is expected to generate power for some 450,000 households. The first turbines are expected to be connected in 2017.
Energinet.dk will install the substation, scheduled for installation later in 2016. The substation will be positioned on a four-legged jacket put in place by pile driving. Lloyd’s Register says this activity generates noise levels that potentially could have a negative impact on marine life.
The team will deploy an airgun to trace an acoustic signal in proximity of the wind farm. Energinet.dk can then integrate the captured data in order to ensure that the noise impact on the nearby marine environment is considered and that any necessary mitigation measures are put in place, says Lloyd’s Register.
The investigation will adhere to guidelines recently implemented by the Danish Energy Agency to address the underwater noise impact from construction of offshore wind farms.
