Site Assessment of the Floating Wind Turbine Hywind Demo

This Site Assessment predicts which environmental conditions an object at the Hywind Demo site will be exposed to. The work is based on 2 years of data from a Seawatch buoy located at the site. By use of Gumbel distributions the 50 year extreme values of wind gust at 3.5 m height (30.5 m/s), ocean current speed at 20 m depth (1.4 m/s) and significant wave height (13.3 m) have been found.
