LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Measurement campaigns & results – OWA – RWE GyM site – Carbon Trust 9 Preliminary results from Offshore Wind Accelerator Project Above results are based on 1.5 days out of nearly 3 months of data collected to date The data are processed using an offline post-processing algorithm (FLiDAR correction algorithm V2) rather than on-board (real time) algorithm on the FLIDAR Wind speeds above 90m (n of points >=40) Y= *x R²= Wind 70m (n of points >=40) Y= *x R²=

LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Summary and conclusions 10 FLiDAR is a highly accurate wind flow measurement device due to the combination of mechanical stabilization and software based measurement adaptation FLiDAR is an autonomous renewable powered offshore measurement device OWA/ GyM (Irish Sea) preliminary/ sample results show that FLiDAR measurement accuracy in wind speed is equivalent with the one obtained in the Belgian trial (r² = 0.994) OWA/ GyM preliminary/ sample results show that FLiDAR wind direction measurement is improved with the version 2 algorithm (r² = 0.976) Further processing of OWA/GyM results for the full period of the trial is underway
