In the North Sea, the construction of wind parks using pile driving forms a threat to porpoises, since they have a very sensitive auditory system. In order to protect this species, the construction work has to be stopped when they are nearby. The purpose of this project is to design a low-cost buoy which should be able to detect these animals in their natural environment and subsequently serve as a supportive device for offshore workers. Additionally, a proposal for a tracking device which can be directly attached to the animals was made. To achieve these objectives, research was conducted on requirements for buoys in North Sea conditions, the behaviour of porpoises, and technical components as well as the necessary software for detection. This report proposes a design for a buoy to meet these objectives.
