Meteorology
UL International GmbH
A fundamental knowledge of environmental data is essential, not only to the design of wind turbines, but also e.g. to the selection of installation equipment and the operating concept to be adopted. Moreover, all cost-effectiveness calculations are based upon yield forecasts which, specifically, cannot be established in the absence of proven wind statistics.
Accordingly, a number of meteorological variables are recorded on the measuring platform, including the following:
- Wind speed
- Wind direction
- Air temperature
- Atmospheric pressure
- Atmospheric humidity
- Atmospheric density
- Rainfall
- Total radiation
- UV insolation
- Visibility
- Number of lightning strokes
For the measurement of meteorological variables, the platform is provided with a wind measuring mast over 80 m in height, such that the maximum height of measurement is 103 m above LAT (Lowest Astronomical Tide). Meteorological parameters are measured using appropriate sensors, which are fitted to the measuring mast and the lattice structure of the platform at various heights.
The object of technical investigations is the accurate recording of meteorological conditions in the lower atmospheric boundary layer. Meteorological parameters are measured using appropriate sensors, which are fitted to the measuring mast and the lattice structure of the platform at various heights.
Extensive sensor technology for the recording of platform dynamics also allows the analysis of the reciprocal effects of wave and wind forces in relation to the foundation structure. Technical measurements are recorded by DEWI in cooperation with BSH.
Results obtained contribute significantly to the improvement of data records for the marine area under investigation. The evaluation and application of data will allow existing risks in the design, construction and operation of offshore wind farms to be reduced. Accordingly, both manufacturers and investors will enjoy greater security in terms of the construction of installations or the appraisal of cost-effectiveness. Meteorological measurements from the platform can also be used for the improvement of weather forecasts.
