1 FINO Technical and Environmental Research Platforms for the Benefit of the Offshore Industry Andreas Beeken & Detlef Kindler, BALTEXPO, Gdansk 2011

2 Project Overview FINO Forschung in Nord- und Ostsee (Research at North and Baltic Sea) Financed by the Federal Environmental Ministry Aim: Installation of research platforms close to future offshore wind farms Platform to investigate the environmental offshore conditions Creation of comprehensive meteorological, hydrographical, technical and biological data base

3 Location FINO 1 FINO 3 FINO 2 Alpha Ventus, Borkum West Dan Tysk, Sandbank 24 Baltic I+II

4 Technical Facts Research Platform Location Operator Commissioning Height Water depth Distance from coast Foundation Platform size Heli pad FINO 1 North Sea GL GH September m 28 m 45 km Jacket 16*16 m yes FINO 2 Baltic Sea GL GH May m 24 m 31 km Monopile 12.2*12.2m no FuE FINO 3 North Sea GmbH, FH August m 23 m 80 km Monopile 13*13 m yes Kiel redundant energy supply (up to 4 generators), l tank in monopile or container generators, operating-, measurement- and communication systems placed in weather proofed and air-conditioned containers data communication via satellite and radio link; online surveillance

5 GLGH assignments at FINO Coordination of construction, installation and commissioning of platform FINO 1 (2001 to 2003) Operational management, maintenance, coordination of ship and/or heli trips to the platform (FINO 1 since 2003, FINO 2 since 2010) Coordination of current and future research projects (FINO 1, FINO 2) Mast design, layout and operation of meteorological measuring program at FINO 3 (since 2006) GLGH

6 Objectives of the FINO Research Program The high level objectives of the three FINO platforms and of associated research are to gather information 1. on the offshore environment in order to better predict its impact on the planned offshore wind farms 2. on the possible influence of the new offshore technology on the maritime environment. Create knowledge to improve design, construction and operation of offshore wind farms. Olaf Robenek

7 Research at FINO Meteorology Wind speed and direction at different levels up to 100 m above see level, temperature, humidity, air pressure, global radiation, UV-A radiation, rain Oceanography Wave height, period and direction, current velocity and direction, sea level, water temperature, salinity, oxygen and pressure Further technical investigations Load impact on structure, acoustic measurement during ramming, registration of ship traffic Biological data Marine growth on the underwater structure, benthos and fishes, migratory behaviour of birds flight counts of bird Photo: AWI

8 FINO 1 vs. FINO 3 different mast and boom layout Significant flow distortion effects at FINO1 lesson learned: switch to triangular mast shape FINO 1: Square Base Prevailing Wind DirectionSW FINO 3: Triangular Base

9 FINO3 Mast & Measurements Design 106 m Triangular mast on Northern edge Three possible boom directions Upper most cup (NOT top) height 106m 9 wind measurement levels 30 to 106m: 16 cups, 2 sonics, 3 vanes 50, 70 and 90 m levels with 3 cups Temperature & humidity sensors at 3 levels Air pressure and rain sensors Main and backup data loggers Mains (diesel-gen-set) and solar powered Cup Sonic Vane T & RH Rain Radiat. 30 m

10 Extreme Wave Heights: Storm Britta, 01 Nov damage to platform 20 m FINO m C.D. 10 m Lower platform +15 m C.D. Hmax ~16 m Hs = 9.77m Photo: GL 0 m C.D. = LAT

11 Storm Sören, 04 October 2009 Hs = 6,40 m Hmax = 10,24 m Main wave periode 11,8 s (corresponds to 200 m wave length) Main wave direction 320

12 FINO Database Data Provision to the Public

13 FINO Database User registered Database data users User (as at 01 June (by June 2010) 2010) Research Industry Authorities Others

14 Which Purpose do FINO Data serve? Research Industry Wind physics Ocean physic Environmental monitoring meteorological models oceanographic models Energy yield assessments Load assessments 7 10 Access and logistics others

15 Summary and Outlook FINO platforms deliver continously reliable data Data accessible for public online Research, Administration as well as Industry benefit from one common source of information FINO Data has led to better understanding of offshore environment and potential impact of offshore wind farms GL Garrad Hassan has the experience from 3 FINO Platforms
