Oldbaum Services, a wind energy consulting services provider, in partnership with Leosphere, has launched 1GW of offshore wind data campaigns at two of its French offshore wind sites.
As part of this assessment, the company has deployed two 3DWINDCUBE 400S Scanning LiDARs from Leosphere, which the company hopes will help make the best use of wind resources available at both locations and reduce the costs associated with offshore wind development.
Oldbaum provides wind data interpretation and consultancy services that 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. The test represents 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, the company said.
