  • The other advantage of wind turbine is that, you can install it at land or at sea. Wind farms are best if you would like to produce more electricity if you needed a high volume of it. Wind energy is the cheapest and cleanest renewable energy resources.

Artificial Islands For Offshore Wind Power

  1. 1. Artificial island (‘s) for the Construction and O&M of offshore wind farms     Chris Westra ECN / We@Sea / HEDEN
  2. 2. Offshore wind energy in the Netherlands: 2008: 228 MW (1 th round) 2013 – 2015: 950 MW (2 nd round) 2015 – 2020: 5000 MW (3 th round) 2020 – 20??: 15.000 MW future
  3. 3. Implementation 6000 MW and more…
  4. 4. Water policy plan: 2010 – 2020 Place for 6000 MW Spatial planning (& ship safety) Conclusion: far offshore “ IJmuiden Ver”
  5. 5. Ambition of the Dutch neighbors at sea <ul><li>Germany: </li></ul><ul><li>1500 MW in 2011 and </li></ul><ul><li>25.000 MW in 2030. (Pilot Alpha Ventus) </li></ul><ul><li>United Kingdom: </li></ul><ul><li>At present 600 MW in operation </li></ul><ul><li>1500 MW under construction </li></ul><ul><li>‘ Round 3’: 25.000 MW </li></ul>
  6. 6. With this ambitions, there is a need for islands at sea: <ul><li>to build and maintain offshore wind turbines on locations far at sea </li></ul><ul><li>building stones for an European offshore electrical grid </li></ul><ul><li>test site for offshore pilot wind turbines </li></ul><ul><li>international service point for offshore wind energy </li></ul>
  7. 7. Spatial planning Germany uk 1. Wind area’s (dark bleu) for round 3: 2015 – 2020 “ IJmuiden ver” (2) 5000 MW “ Borssele” (1) 1000 MW 2. Search area’s in light bleu 3. Beyond 2020 Area’s indicated by arrows
  8. 8. Optimisation building and O&M With artificial islands !
  9. 9. A first design
  10. 10. Primary functions: <ul><li>harbor for construction and O&M of wind farms </li></ul><ul><li>site for offshore transformer station </li></ul><ul><li>hotel for personnel </li></ul><ul><li>test site offshore wind turbines </li></ul><ul><li>warehouse for spare parts </li></ul><ul><li>International logistic hub for offshore wind farms (NL, U.K. & DE) </li></ul>
  11. 11. Assembly of wind turbines
  12. 12. Assembly and commissioning of a complete wind turbine in the harbor and…...
  13. 13. … transport and place the turbine in one lift Ballast Nedam IHC Merwede
  14. 14. An island at sea will extend offshore weather windows
  15. 15. Our vision for the future <ul><li>development of harbors to facilitate the large scale implementation of offshore wind energy at the North Sea </li></ul><ul><li>contribute and accelerate the implementation of offshore wind energy </li></ul><ul><li>cooperating with U.K. and DE to find strategic sites at the North Sea to build artificial islands for offshore wind power </li></ul><ul><li>contribute to the development of a European offshore electrical grid </li></ul>

  17. 17. Potential locations: “ North Clay-land” “ North-East Friesland” “ IJmuiden op zee”
  18. 18. Islands as part of an offshore network (electrical infrastructure) “ North Clay-land” “ North-East Friesland” “ IJmuiden op zee”
  19. 19. Islands as a part of the offshore infrastructure according the report: “Net op zee” Offshore electrical infrastructure
  20. 20. A substation on a jacket and on an island the advantage of a substation on an island
  21. 21. Artificial islands fit well in the development of an European offshore grid
  22. 22. FLOW: Near shore Far offshore On shore 120 m 1) 100 m 1) reduce costs by 20% accelerate Artificial islands fit well in the new Dutch R&D offshore wind energy programme FLOW (
