Arkona Becken Southeast: The construction area is 35 kilometers northeast of the island of Rügen and directly southeast of the Wikinger offshore wind farm, which is already under construction. 60 wind turbines are installed. They should generate an output of 385 MW. This means that the wind farm can theoretically supply 400,000 households with electricity. Construction should be completed by 2019. The substation is already in place. It was anchored in the construction site with a jacket foundation at the end of July 2017.
Measured at the same distance, the noise level of a pile-driving underwater is many times higher than that of a rocket taking off on land (see also hydro noise – doubling every 10 years). Due to the high water density, sound travels 4.3 times faster than in the air, and its range is correspondingly greater. Whales, seals, and many fish use sound for vital activities. Natural background noise in the water is a prerequisite for your communication, your search for partners and food, avoidance of enemies, and your orientation.
Thanks to the Big Bubble Barrier’s clever use, the noise level is reduced by up to 5% during pile driving.
