1 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Wind at Sea session, EWEA 2013 | | February 2013

2 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Product specifications – Technology characteristics 2 BUOY Industry standard buoy with long track record Designed for harsh environment ENERGY Fully autonomous, solar and wind powered Offshore components Dimensioning for European waters No fossil fuels, no environmental harming liquids MECHANICS Gimbal based motion stabilisation LIDAR WINDCUBE®v2 Offshore Electronics protected with water proofing beyond standard offshore techniques for marine environment IEC salt atmosphere compliant Data correction to account for unit motion (software)

3 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Product specifications – Measurements and Communication 3 Wind & Environmental Measurements Full WindCube V2 capabilities (up to 200m height, 1Hz and 10’ averages data) Sonic Anemometer (FLiDAR deck) Temperature, pressure, humidity (FLiDAR deck) Sea temperature (FLiDAR hull) Waves and currents (under development) Data communication Satellite: 10’ averages once a day GPRS: Real time full data access Wi-Fi: Near FLiDAR operations (full data access) Storage: On board and SFTP

4 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Measurement campaigns & results – Belgian trials 4 Jul – Dec 2011 One month test next to Oostdijkbank platform 20Km offshore the Belgian coast Conditions during test: Max. significant wave height: 5m, period from 4 to 10s Wind up to 25m/s Oostdijkbank Radar Platform Feb-March 2011 Near-shore Proof of concept

5 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Measurement campaigns & results – Belgian trials 5

6 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Measurement campaigns & results – Belgian trial - DTU report 6 Wind speed and 100m

7 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) Measurement campaigns & results – Belgian trial - DTU report 7 Accuracy deviations in 10’ averages with respect to wind direction and wind speed intensity

8 LOW COST AND FLEXIBLE OFFSHORE WIND MEASUREMENTS USING A FLOATING LIDAR SOLUTION (FLIDAR™) VALIDATION IN IRISH SEA AGAINST FIXED METMAST 8 Carbon Trust Offshore Wind Accelerator Project RWE - Gwynt y Môr site Note: OWA (Offshore Wind Accelerator) is not the same as OWA (Offshore Wind Assistance)

9 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=

10 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
