Forecast lidar on the up
Babcock’s floating system at stage 2 of Carbon Trust road map
Babcock’s Forecast system has reached stage two of the Carbon Trust’s Offshore Wind Accelerator (OWA) road map for commercial acceptance of floating lidar.
The company said the Zephir-based lidar system had “consistently exceeded the required KPI’s for accuracy and availability as verified by the Carbon Trust and DNV-GL”.
Babcock business development manager Chris McConville said: “We are delighted to have our approach to floating lidar validated by the Carbon Trust and OWA partners in the most comprehensive validation conducted to date.
“While this was a six month validation project, Forecast has actually been offshore for 16 months in the Gwynt Y Môr wind farm, including an initial development phase where the hull and mooring systems were tested, making this one of the longest continuous deployments of a floating lidar system.
“Forecast has demonstrated that it can withstand demanding offshore weather conditions all year round, measuring winds reaching 100km/h in waves over 8 metres high, and continues to provide consistently high data availability.”
Forecast is based around Babcock’s low motion buoy and is designed specifically to address the known adverse effects of motion on data accuracy.
It replicates the conditions of a fixed mast “as closely as possible” while delivering the cost benefits of a floating solution, the company said.
Carbon Trust chief operating officer Michael Rea said: “The trials are significant for both individual projects and also for the offshore renewables industry as a whole.
“The results of this research highlight how the development of innovative technology can play a very real and critical part in helping us reach this aim.”
The full results of the validation campaign will be presented by the Carbon Trust later this year.
