Objectives of the Project:
To develop and document a combined three-model methodology for the optimum estimate of wind power offshore applied to European Union waters. To make detailed SODAR measurements of on-to-off- and off-to-on-shore winds on the East Coast of England and on the Dutch coast
To produce a CD-ROM with a user-friendly GIS interface that will allow the end user:
- To find out the long term wind power resource at a given offshore location in European Union waters
- To assess the expected interannual and seasonal variability at that site - To deduce the expected wind speed distribution at the location of interest - To investigate whether the area of interest is unsuitable for offshore wind farm siting due to excessive wind/wave loading and extreme gust events To make and document a case-study at prospective offshore wind farms sites proposed by Elsam and at a Dutch 100MW demonstration near-shore wind farm site due to be built in order to validate the CD-ROM database at these sites where observed data exists
Technical Approach:
The objectives of the project will be achieved by:
- Interpolating geostrophic wind speeds from upper air and surface pressure data.
- Extrapolating the geostrophic wind to the sea surface by use of WAsP. - Modifying the near coastal winds using a Coastal Discontinuity Model (CDM). - Combining the three models and refining in the light of the available observed data including SODAR data collected during the project. - Statistically assessing offshore wind/wave loading, extreme gust events, seasonality and wind speed distributions from observed and model data. Expected Achievements:
- A combined three-model methodology for the assessment of offshore wind power resource
- The quantification of long term wind power resource, seasonality, wind/wave loading, extreme gusts and wind speed distribution on a grid covering European Union waters.
- A CD-ROM based GIS software package based on the data grid above relevant to the needs of the wind energy industry for the optimum assessment of potential offshore wind farm sites.
