AB - In this thesis, we have performed several processing methods for analysing available hydrophone data. This was done in order to study the sound pressure levels in the vicinity of an offshore wind farm, and to identify energetic tones. These sound pressure levels was then compared to the environmental wind and wave conditions at the corresponding time. Further, we have modelled how an acoustic signal from a wind turbine will propagate, and how the transmission losses will change under different forcing conditions. We have studied both scattered and continuous measurement series, and did modelling for two locations; by FINO1 offshore platform in Germany, and the location of the floating wind farm Hywind Tampen in Norway. The ocean is a huge and valuable natural resource. Throughout the study, we have also discussed the importance of the research we have been performing. We have briefly looked into the legal framework for licensing offshore wind energy, and the importance of environmental assessment in order to live in harmony with other stakeholders. We have also looked into how we can contribute to more and deeper understanding within this field of study, especially in regard to marine species.
