Nordsee One will not only produce environmentally friendly energy, but the comprehensive environmental monitoring program during the planning phase, construction and operation will also ensure that impacts from construction and operation of the wind farm will be minimized. During the course of the public permitting process lead by the Bundesamt für Seeschifffahrt und Hydrographie (the BSH), Nordsee One conducted three years of environmental monitoring and will conduct further monitoring during construction and operation. Altogether more than seven years of environmental monitoring will be performed , providing a comprehensive understanding of the marine environment on and around the site. Where underwater noise generated by the wind farm's construction may impact on the surrounding environment, Nordsee One will, use the latest state-of the art noise reduction techniques and will conduct noise measurements to ensure that the noise reduction measures are effective.
