During July 2009 the first of twelve offshore wind turbines has been erected within the German territorial waters. In the meantime all wind turbines of the first German offshore wind farm "alpha ventus" are installed and the commissioning has been finalized. However before an installation and commissioning can be realized, detailed information regarding wind conditions are required. Therefore the Germanischer Lloyd (GL) was responsible for the erection of the first research platform "Fino 1" and also operates this platform in the North Sea. The second platform "Fino 2" is located in the Baltic Sea and is also under operation by GL. In the meantime the third research platform "Fino 3" in front of the island Sylt has been commissioned. This structure has been certified by GL and wind data are also collected under GL's responsibility. However for the installation of offshore wind turbines in the deep water zone less information related to wind loads and boundary conditions are available. Thus additional research work is required in this field of wind engineering. This means not only additional research work for the construction, but rather more for the boundary conditions. Within these boundary conditions the load assumptions, wind speed and wave height are determining the behaviour of the structure.
