Frank Thomsen DHI frth@dhigroup.com   ‘The European Commission has just published the final report of the MaRVEN study on the environmental effects of noise, vibrations and electromagnetic emissions from MREDs (Marine Renewable Energy, Vibration, Electromagnetic fields and Noise). MaRVEN provides an in-depth analysis of studies on the environmental effects of noise, vibrations and electromagnetic emissions during installation and operation of wind, wave and tidal energy devices. On-site measurements and field experiments to fill priority knowledge gaps and to validate and build on the results obtained in reviews were undertaken as well. Finally, we outline a programme for further research and development with justified priorities. Click here to find out more details.
