Method For offshore assessments EuroWind statistically evaluates all available wind measure- ments. In addition, reanalysis data, such as e.g. data of the NCAR/NCEP project, can be consulted in order to determine and complete the existing measuring data (the adjoining figure shows the long term average wind speed of the NCEP reanalysss).
				Regional variations of the long-term average wind speeds over the North Sea and the Baltic Sea using the example of NCEP/NCAR reanalyses.

By using the program system WIEN (certified acc. to DIN EN ISO/IEC 17025:2005) it is guaranteed that the model results are best possible adapted to the measuring data in the simulation area and that they correspond to the local conditions of the region even at those places where no long-term wind measuremnts are available. This is achieved by predefining the physical drive mechanisms, such as e.g.

			roughness parameterization depending on the sea conditions,
			thermal temperature profile above sea,
			wind statistics from several sites

to the three-dimensional atmospheric flow model as input data.

Since the wind field within offshore wind farms are not only significantly influenced by the local conditions but also by the superimposed synoptic weather conditions, the wind field simulations are being performed for larger areas of about 150 km x 150 km.

Being an active member of the wind expert advisory board of the Bundesverband Windenergie (Federal association of wind energy), wind resource- and energy yield assessments by EuroWind comply with the specifications supplied by the expert advisory board concerning the quality and the scope of wind resource- and energy yield assessments. To our customers this mean approved, bancable results and an increased reliability in planning for the design and financing of wind farms.

		Scope of service and advantages of our procedure:
		Comparison of different turbine types Optimization of the hub height Optimization of the wind farm configuration Roughness parameterization depending on the sea conditions Consideration of the thermal layering above sea Consideration of wind statistics from multiple different sites Application of an advanced three-dimensional flow model Exact vertical wind profile also for large hub heights
