Dong Energy’s 258MW Burbo Bank 2 in the UK is the first offshore project to proceed on the back of floating lidar wind data.

The Danish developer decided to press on with construction of the scheme, which will feature 32 MHI Vestas V164 8MW turbines, in December.

A Flidar buoy was the only device measuring the site 8km off the coast in Liverpool Bay from June 2013 to September 2014. The unit completed a final period of post-validation against an offshore met mast.

Flidar general manager Reinhardt Stevens said: “The speed, flexibility and relatively low cost of floating lidar technology is changing the way offshore wind is measured.”

The Flidar technology was developed by renewable energy consultancy 3E and Offshore & Wind Assistance, a subsidiary of marine contractor GeoSea.

The device is made up of a Mobilis buoy with a Leosphere Windcube lidar held in a passive mechanical stabilisation system. It has been tested and validated against fixed met masts in the North Sea and Irish Sea.

Burbo 2 is expected to be commissioned in 2017.
