Offshore Wind Infrastructure Applicaiton Lab - Launch 2012-01-24 - REpower

  1. 1. Offshore Wind Energy ResearchOWI-LabAntwerp, 24th of January 2012Norbert Giese, REpower Systems SE
  2. 2. Offshore market in 2011 in Europe Total Installations 1991 -- 2011 Total Installations 1991 2011 - 1.371 WTG (only in 2011: 235) - 3.813 MW (only in 2011: 866 MW) - 53 projects (only in 2011: 9) - 9 countries - Leading Markets so far: UK, DEN, BEL, NED, GER Source: EWEA
  3. 3. Offshore Wind Industry, last 20y + next 4y Global Offshore Wind Industry in an important (or critical?) phase Global Offshore Wind Industry in an important (or critical?) phase 1991 – 2011 3,8 GW grid connected -Mainly Denmark and UK -Mainly nearshore, shallow water, 2-3 MW turbines 2012 – 2015 roughly 12 GW in serious development/order - 15 times more than before - thereof: 1/3 in UK and 1/3 in Germany (Final Investment decision in Germany 7 billion €) 1/3 in other European countries and 2/3 with financing 1/3 so far without financing
  4. 4. Offshore? What kind of offshore? Offshore II Offshore Offshore II Offshore II Offshore III Offshore III 1. 1. Near to shore, Near to shore, 1. 1. Far from shore, Far from shore, 1. 1. Far from shore Far from shore < 20 km, < 20 km, more than 20 km, more than 20 km, mainly 5 -- 15 km from mainly 5 15 km from up to 150 km from the up to 150 km from the the nearest harbour the nearest harbour nearest harbour nearest harbour 2. 2. Shallow water, Shallow water, 2. 2. Deep water, Deep water, 2. 2. Very deep water Very deep water < 20 m, < 20 m, up to 60 m water depth up to 60 m water depth mainly 5 -- 15 m water mainly 5 15 m water depth depth 3. 3. Real offshore turbines Real offshore turbines 3. 3. For the time being For the time being 3. 3. Mainly onshore Mainly onshore needed needed floating foundations floating foundations turbines used with turbines used with needed needed 2 -- 3 MW 2 3 MW 4. 4. Strong or very strong Strong or very strong 4. 4. Strong or very strong Strong or very strong 4. 4. Strong wind regimes Strong wind regimes wind regimes wind regimes wind regimes wind regimes
  5. 5. Capital Costs for Offshore Wind Projects 3500£ x 1,15€/£ = 4025€ 3250£ x 1,15€/£ = 3738€ 3000£ x 1,15€/£ = 3450€ 2750£ x 1,15€/£ = 3163€Project CAPEX (£M / MW) www.bwea.com, (2009)
  6. 6. Current Offshore-WEC - Installed Others Medium Areva speed M5000 Vestas REpower V90, V112 5M High Siemens REpower speed 2.3-93 6M Siemens Bard 3.6-107/120 5.0 Direct Siemens, 6 MW drive 3 4 5 6 7 8 9 10 MW
  7. 7. Future Offshore-WEC – Installed & Announced Mitsubishi Others 6-7 MW Bard 6.5 Gamesa Gamesa 5 MW 6-7 MW Medium Areva Vestas speed M5000 7 MW Vestas REpower V90, V112 5M High Siemens REpower speed 2.3-93 6M Siemens Bard 3.6-107/120 5.0 GE Alstom, Direct 4 MW Nordex AMSC drive 6 MW 10 MW 3 4 5 6 7 8 9 10 MW
  8. 8. (Wind) Data Offshore -Do we have enough wind data offshore? -Do we understand the offshore wind farm models? Wakes? -Do we have enough data about the offshore soil?
  9. 9. Maritime Installation Concept IFor the first time in the world a fully pre-assembled wind turbine installed offshore - Total lift of 655 tonnes
  10. 10. Maritime Installation Concept II
  11. 11. Offshore Substructure I Improved frame design resulted in faster and Improved frame design resulted in faster and Jacket installation started 23 July 2010 Jacket installation started 23 July 2010 more solid pre-piling operation more solid pre-piling operation Finished on 17 October 2010 Finished on 17 October 2010 Piling started 1 May 2010 Piling started 1 May 2010 Transportation by barges, installation with Transportation by barges, installation with Final piles completed on 14 July 2010 Final piles completed on 14 July 2010 RAMBIZ RAMBIZ Average time 2.5 days/location Average time 2.5 days/location 1 day // location 1 day location
  12. 12. Offshore Substructure II
  13. 13. Rotor Blades Largest composite structures in the world Largest composite structures in the world Design Based on SBA-Template (monthly) Based on SBA-Template (monthly) Material Changes compared to previous month Changes compared to previous month Production … …
  14. 14. New O&M Concepts: Three self-operating ElementsJack-up Crane Vessel:Jack-up Crane Vessel: For up to 90 people For up to 90 people Three-shift model Three-shift model Crane is designed to lift weights up to 500 tons Crane is designed to lift weights up to 500 tonsPlatform Supply Vessel:Platform Supply Vessel: For staff transports, supply of the crew, delivery For staff transports, supply of the crew, delivery of spares and tools (60 people // 300 tons cargo) of spares and tools (60 people 300 tons cargo) Active motion compensating gangway for Active motion compensating gangway for transfers up to 2.50 m waves transfers up to 2.50 m wavesWorkboat:Workboat: For minor repairs, inspections or preparatory For minor repairs, inspections or preparatory work work = Service and maintenance of up to 240 = Service and maintenance of up to 240Start of operation: 2014 turbines // year turbines yearStart of operation: 2014
  15. 15. 100 % reliability for all components - Main components of course - But also the small parts, causing offshore high O & M costs - Big difference to the Onshore Wind Industry
  16. 16. Grid Connection and Storage of EnergyBEATRICE PROJECT● Talisman Energy & SSE - 2x 5M - Installed 2006 & 2007● Water depth: 45 m● Distance to shore: 25 km
  17. 17. Offshore Revolution: New wind farm design Based on Onshore Wind each wind turbine is a full power station on it´s own vs. An Offshore Wind power station with “stupid” wind turbines
