Since 2018, the so-called Faunaguard Schweinswal module or the ACOUSTIC PORPOISE DETERRENT (APD), according to the manufacturer, has been used in the German AWZ for the overgrowth of porpoises in the run-up to ramming of offshore wind turbines. By 2017, as in Sound protection concept of the BMUV in 2013 described, Pinger and Seal Scarer used the ramming position for the overgrowth of the animals from the 750 m radius. The Faunaguard module sends high-frequency signals in the range of 40 to 120 kHz, which are therefore specifically on the hearing of porpoises are oriented and should contribute to a lower noise pollution of the marine environment.
At the end of 2021, the results of the faunaguard's degeneration efficiency as part of an IM Order of the BSH -performed study published. In the near area between 750 m and 2 km away, the detection rates of pork whales were comparable to those when using Seal Scarern. In addition, in contrast to Seal Scarern, no displacement effect was noticeable. The Measurements took place in the course of the offshore construction site activities, which is why it could not be clarified to the extent to which other factors such as ship's noise, played a role in the exertion effect. Therefore, the authors of the study recommended that to carry out a supplementary study in which Regardless of the construction activities, the fragrance effect of the faunaguard is examined for pork whales.
In the project, this examination, which is independent of construction activities, is intended to investigate the framework effect or distance 1. Examination results are available).
