Trinity House Lighthouse Service in the UK has joined forces with research group Qinetiq to test a buoy-mounted device for collecting wind resource data. The SeaZephIR uses Qinetiq's lidar system atop a huge 11 metre high buoy tethered to the sea bed. Qinetiq says its lidar can measure wind speed and direction at heights beyond the tallest wind turbines in use today. According to Steve Squires from Trinity House, the SeaZephIR will be significantly cheaper than conventional meteorological masts because the buoy is easier to deploy. "The consents process is also much shorter because the footprint of the device on the seabed is much smaller than for a met mast," he says.
