    With a new and innovative technology, it is now possible to comply with exciting legislation on noise reduction during installation of offshore wind turbines. According to legislation from the EU the sound emissions from the installation of windmills at sea must be reduced so the threat to the marine mammals are minimised. Traditionally, the water […]

    The installation of driven piles in the marine environment, whether along quaysides or – for example – during installation of offshore foundations, without mitigation is likely to produce noise levels capable of causing injury and disturbance to marine animals. Such effects, although incidental to consented activities, have the potential to conflict with a range of […]
