Underwater noise of operating wind turbines
Author: Discovery of Sound in the Sea
As a turbine operates, vibrations inside the nacelle (the housing that contains the generator, gearbox, and other parts) are transmitted down the main shaft of the wind turbine and into its foundation. These vibrations then propagate into the water column and seafloor. Mechanical noise generated by offshore turbines is concentrated at low frequencies below 1kHz, generally below 700 Hz. Bockstigen-Valar, Sweden Underwater recording taken less than 50 m from a 500 kW turbine operating at the Bockstigen-Valar offshore wind farm (Baltic Sea, . . .

Author: Botero-Bolívar, Laura; et al.
Abstract. The growing demand for offshore wind energy has led to a significant increase in wind turbine size and to the development of large-scale wind farms, often comprising 100 to 150 turbines. However, the environmental impact of underwater noise emissions remains largely unaddressed. This paper quantifies, for the first time, the underwater aerodynamic noise footprint of three large offshore turbines (5 MW, 10 MW, and 22 MW) and wind farms composed of these turbines. We propose a novel methodology that integrates validated wind . . .

Key takeouts The loss of amenity for a surrounding landowner due to wind turbine noise can form the basis of a successful claim in private nuisance. This is the first time a successful claim has been made on these grounds against a wind energy facility operator in Australia. Correctly understanding and applying applicable noise standards is a critical component of managing overall legal risk. For the first time, judicial guidance has been provided on how to interpret and apply various . . .

Author: Chang, Hao-Yi; Lin, Tzu-Hao; Anraku, Kazuhiko; and Shao, Yi Ta
Abstract Short-term exposure to strong underwater noise is known to seriously impact fish. However, the chronic physiological effects of continuous exposure to weak noise, i.e. the operation noise from offshore wind farms (OWF), remain unclear. Since more and more OWF will be built in the near future, their operation noise is an emerging ecological issue. To investigate the long-term physiological effects of such underwater noise on fish, black porgies (Acanthopagrus schlegelii) were exposed to two types of simulated wind farm . . .
