Oldbaum to Collect Wind Data off French Coast

Oldbaum Services has 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 completed third party validation tests with DTU and DNV GL.

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.

“Oldbaum Services and Leosphere have been working together as solid partners for many years, and Oldbaum Services has an excellent track record of utilising Leosphere’s Lidar Instrumentation to deliver successful wind energy projects all over Europe,” explained Oldbaum’s Technical Director Andy Oldroyd.

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% between met-mast and scanning device at long ranges, and mean speed errors inferior to 0.5m/s.
