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 an ongoing project from 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.
