Abstract

In this report a consequence study regarding the surfers wind conditions east of the planned new harbour area of Hanstholm. At this harbour area, 10 new 150m tall 3MW wind turbines are planned.
Both the harbour constructions as well as the wind turbines could potentially alter the wind conditions on the lee side, which is an important area for wind and kite surfers. In this study, both changes in mean wind velocities as well as the turbulence level are investigated for the surf area between a location called ”Fish Factory” to the location called ”Hamburg”. The interesting wind speed interval is 8-16m/s mainly from west, measured in 10m height. Results are extracted in several downstream locations specified by Grontmij covering the area used for surfing. It is expected that surfing mainly occurs for wind speeds above 10m/s (10m height) and the important parameters both level of mean wind speeds as well as low turbulent conditions within the surf area. In general the impact of wind turbine wake is very limited in the eastern part of the surf area, whereas a reduction in mean wind speed in combination with increased turbulence intensity is seen in the western area.
