11. What About Wind ?

12. AVAILABLE WIND POWER Annual W/m2 200-300 300-400 400-500 500-600 Horns Rev, Denmark Total output = 160 MW Expected annual output = 600 Million KWh Courtesy Jose Blanco and Larry Atkinson, Old Dominion University

13. OBOE

14. The OBOE “Hybrid Energy Preserve” • Utilize more than one energy • generation approach

15. The OBOE “Hybrid Energy Preserve” • Utilize more than one energy • generation approach • – wind + natural gas + wave

16. The OBOE “Hybrid Energy Preserve” • Utilize more than one energy • generation approach • – wind + natural gas + wave • – wind + wave + ocean current

17. The OBOE “Hybrid Energy Preserve” • Utilize more than one energy • generation approach • – wind + natural gas + wave • – wind + wave + ocean current • This better matches production variations with • consumption patterns, • and it better utilizes • infrastructure

18. Hybrid Offshore Wind and Natural Gas Combustion can Provide Baseload Power • ADVANTAGES: • Provides high-value baseload power • Avoids utility needfor land-based “spinning reserve”to accommodatewind variability • Submarine powercable to shore more secure, with less environmental impact than gas pipeline • Avoids onshoresiting challenge of finding cooling water for land-based gas power plants • Prolongs life of fossil gas reservoir as bridge to marine biogas future

20. OBOE Will Engage New Technologies • Technology transfer to offshore wind from FAU research on remote condition monitoring and servicing

21. OBOE Will Engage New Technologies • Technology transfer to offshore wind from FAU research on remote condition monitoring and servicing • New platform and mooring designs for wind turbines – one example is the Principle Power’s WindFloat semi-submersible

22. The WindFloat Semi-Submersible TECHNICAL SPECIFICATIONS • Power rating – 5 MW • Tower weight – 400 tons • Turbine weight – 400 tons • Turbine height – 100 m • Rotor diameter – 125 m • Hull Draft – 20 m • Displacement <8000 tons • Water depth >50 m • Mooring – 60o/6 lines

23. The WindFloat Semi-Submersible Currently under testing at UC-Berkeley

24. OBOE Will Engage New Technologies • Technology transfer to offshore wind from FAU research on remote condition monitoring and servicing • New platform and mooring designs for wind turbines – one example is the Principle Power’s WindFloat semi-submersible • Add-on wave power • buoys

25. Other Issues • Better characterization of the offshore environment (operational & extreme) • Mapping of offshore energy resources and other ocean uses • Follow regulatory developments at both state and • federal levels
