It analyses mitigation measures which have been applied in related projects and assesses their applicability to offshore pile driving. Based on this, suggestions for new mitigation measures are made. The report identifies two methods which are promising to be both applicable and effective in reducing underwater noise arising from offshore pile driving. Both methods are considered to be generally compatible to the working processes at sea. Although further engineering work would be needed, they could be brought into practice within a few months. It is concluded, that noise mitigation measures offer good opportunities to reduce the impacts of underwater noise arising from the construction of offshore windfarms. For the offshore industry, noise mitigation may prove to be beneficial as their application may allow construction works in areas and times when restrictions are needed to protect sensitive species.

It analyses mitigation measures which have been applied in related projects and assesses their applicability to offshore pile driving. Based on this, suggestions for new mitigation measures are made. The report identifies two methods which are promising to be both applicable and effective in reducing underwater noise arising from offshore pile driving. Both methods are considered to be generally compatible to the working processes at sea. Although further engineering work would be needed, they could be brought into practice within a few months. Based on measurements of offshore pile driving, noise emissions of large piles are estimated to reach peak levels of 201-205 dB re 1μPa and sound exposure levels SEL of 175-178 dB re 1μPa at a distance of 500 m. Noise produced from offshore pile driving may be harmful and disturbing to marine wildlife. From literature data it is inferred, that physical impairment may occur above levels (SEL) of 180 dB re 1μPa. As a first proxy for disturbance of marine mammals, the report refers to a level of 140 dB re 1μPa.
