Wind power consultancy Oldbaum Services, deployed two 3D WINDCUBE 400S Scanning LiDARs as part of the wind resource assessment campaigns the company is currently conducting at two French offshore wind sites.
It is the first time that such long range scanning systems are deployed for operational campaigns, after having successfully completed third party validation tests with DTU and DNV GL. Oldbaum’s work will contribute to making best use of the wind power resource available at both locations to reduce the costs associated with offshore wind development.
Oldbaum provides wind data interpretation and consultancy services that efficiently complement Leosphere’s scanning LiDAR, allowing Oldbaum to design and implement cost effective wind resource assessment campaigns to establish the offshore wind regime from onshore for future wind farms as well as optimize their layout design.
The instrumentation Oldbaum selected for the job includes the 3D WINDCUBE 400S Scanning LiDAR from Leosphere, which is able to scan hemispherically up to a distance of 10 km. It scans the wind out to sea, providing Oldbaum with a comprehensive picture of the wind resource available at both sites, returning data using low risk cost effective measurements. The reconstruction of the wind was based on Leosphere’s in-house algorithm recently validated by DNV GL.
Prior to deployment, the 3D WINDCUBE Scanning LiDAR was field-tested and validated by DNV GL on the Janneby test site in Germany. It is the first long range scanning LiDAR to be third-party validated. The results from DNV GL show that the WINDCUBE scanning LiDAR significantly reduces P90 AEP uncertainty and meets the high standards set by the wind energy community, such as correlations of 98 percent between met-mast and scanning device at long ranges, and mean speed errors inferior to 0.5m/s.
