Abstract
The operation and in particular the construction of offshore wind converters
induce considerable underwater noise emissions. It is assumed that small
whales and seals can be affected by noise from machines and vessels, piling and
installation of the wind turbines. Piling, in particular using hydraulic hammers
creates impulsive noise with considerable high energy levels. Currently, only little
knowledge about the effects of different noises to marine life is available. Here, we
present the objectives of the ongoing project of the Laboratory of Applied Bioacoustics
(Technical University of Catalonia): to simulate the generation, radiation and
propagation of underwater noise; to develop forecasting hydro sound models of
offshore wind converters and future noise reduction methods during pile driving;
to determine the impact area of offshore wind farms; to allow the formulation of
recommendations for acoustic emission thresholds; and to develop standard procedures
for the determination and assessment of noise emissions.
