Abstract
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.
