Measurement campaigns & results – OWA – RWE GyM site – Carbon TrustPreliminary 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 2m/s @ 90m(n of points >=40)Y=0.98189*xR²=0.99373
Wind direction @ 70m(n of points >=40)Y=0.96774*xR²=0.97602

Summary and conclusions
• 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
