  1. FINO3 – First results from the 2nd Offshore Wind Energy Research Platform in the North Sea Detlef Kindler EWEC – Warsaw, 2010-04-21

  2. Outline • Introduction to FINO platforms – GL involvements • FINO3 design – measurement layout • Flow distortion by mast effects • Preliminary results wind distribution and statistics • First comparisons to FINO1 • Summary & outlook

  3. FINO Platforms in the North Sea and Baltic Sea Erection dates: 2003 FINO1 2007 FINO2 2009 FINO3

  4. The North Sea Platforms FINO1 and FINO3 FINO3 FINO1 Design and foundation

  5. FINO3 platform and mast layout Main platform 13x13m, mast on Northern corner,lattice tower structure, width 1.2m (top) to 6m (base)

  6. FINO3 mast/boom layout Massive lattice tower structure, solid main columns, booms 3.1 to 8.8 m long

  7. FINO1 – flow distortion effects Square mast base – two boom directions – top cup in cage

  8. Different mast & boom designs  FINO1 experiences used for FINO3

  9. 50 m 70 m 90 m FINO3 boom layout On levels 50, 70, 90m all 3 boom with same cup type

  10. Handling the flow distortion Mast Selection of undisturbed sectors: 2 x 60°for each boom direction

  11. Handling the flow distortion Distribution of wind direction / sectors

  12. Downwind and upwind wake effects on cups Ratio between disturbed and undisturbed wind speedsdown wind wake deficits up to >40%

  13. Undisturbed wind speed time series Max 10 min 29.8 m/s Max 1 sec 36.1 m/s Mean WS, standard dev. and max values from cups at 70 m

  14. System and Data Availability Mid-Sep  pre-commissioning, test operation until Dec

  15. Wind direction and speed distribution WD @ 60m WS @ 70m Polar plots for period Sep 2009 to Mar 2010

  16. Comparison FINO1 and FINO3 Distance FINO1 to FINO3 136 km, direction NNEland distance to SW 50 km (F1) and 200 km (F3)

  17. Comparison to FINO1 (A) storm event (Westerly) on Oct 3, 2009(B) 3 months time series Dec 2009 – Feb 2010

  18. FINO3 vs. FINO1: delay in storm event appearance Wind speed @ 70m Wind direction @ 60 / 90m Delay of 3 to 5 h between FINO1 and FINO3, Westerly wind directions

  19. FINO3 vs. FINO1: Mean Wind Speeds FINO3-Avg 10.14 m/s FINO1-Avg 9.84 m/s Cumulated & monthly mean wind speeds – 3 months only !!!

  20. Summary • FINO3 wind measurements in pre-operation since Sep 2009in full operation since Dec 2009 • Promising approach to handle flow distortion effects • First data on wind distribution and statistics high demand from developers comparison to FINO1, almost 7 years of data • Refinement of processing techniques flow distortion plausibility checks • Data to be fed into BSH FINO data bank by summer this year for public use • “Validation” of mast wake effects by LiDAR comparison Outlook

  22. FINO3 – log profiles (alpha values), betw. 30m & 80m Westerly WD 225°to 285° Easterly WD 45°to 105°

  23. FINO3 vs. FINO1: Weibull statistics FINO 3 FINO 1

  24. FINO3 vs. FINO1: Turbulence Intensity FINO 3 FINO 1 Natural and characteristic turbulence

  25. FINO3 vs. FINO1: Turbulence Intensity Natural and characteristic turbulence
