  • 6. PRINCIPLE POWER INC.
    • ESTABLISHED IN OCTOBER 2007
      • 10 employees
      • Locations in US and Europe
    • MISSION
      • Develop and commercialize the WindFloat
    • TECHNOLOGY
      • Core IP patented, WindFloat system patent pending
    • MARKET
      • Intermediate and deep-water wind sites - Presently untapped
      • Natural evolution of offshore wind development
    Deep-water offshore wind is inevitable
  • 7. WHY OFFSHORE WIND?
    • WHY OFFSHORE WIND?
      • Higher wind resource and less turbulence
      • Large ocean areas available
      • Onshore sites are scarce
      • Capacity of offshore wind is theoretically unlimited
    • WHY FLOATING OFFSHORE WIND?
      • Limited shallow water sites
      • Majority of resource in deep water
      • Large ocean areas available
      • Less restrictions for offshore deployment and reduced visual impact
      • >2 TW resource potential in primary markets
  • 8. OFFSHORE WIND RESOURCE Source: Willet Kempton, U of DE Delaware 20 miles Offshore Nearshore Onshore
  • 9. OFFSHORE WIND – PRIMARY MARKET POTENTIAL AND RESOURCE Source: Risø National Laboratory, Roskilde, Denmark Source: US National Renewable Energy Lab
  • 10. OFFSHORE WIND – CURRENT DEVELOPMENT

  • 12. OFFSHORE WIND CHALLENGES
    • FIXED FOUNDATIONS
      • Water depth
        • Overturning of moment of wind turbines to be mitigated by the foundation
      • Installation of wind turbines offshore
        • Requires large installation vessels
        • Acceptable weather window (sea state limitations)
    • FLOATING FOUNDATIONS
      • Pitch motion
        • pitch acceleration lead to structural fatigue (gyroscopic moment induced yaw)
      • Installation and Commissioning scenarios
        • Need to “keep it simple” influences design significantly
  • 13. THE WINDFLOAT
    • TURBINE AGNOSTIC
      • Conventional (3-blade, upwind)
      • No major redesign
    • HIGH STABILITY PERFORMANCE
      • Static Stability - Water Ballast
      • Dynamic Stability - Heave Plates
      • Efficiency – Closed-loop Active Ballast System
    • DEPTH FLEXIBILITY (>50M)
    • ASSEMBLY & INSTALLATION
      • Port assembly
      • No specialized vessels required, conventional tugs
      • Industry standard mooring equipment

  • 20. IN SUMMARY - WINDFLOAT OFFERS:
    • LOWER DESIGN & DATA COLLECTION COSTS
      • Farm design rather than individual unit
      • Area wide data, rather than unit specific
    • MINIMIZED OCEAN FLOOR & ENVIRONMENTAL IMPACTS
      • Use of conventional anchors
      • Due to reduced bio activity in >50 m depth
    • LOWER INSTALLATION & INSURANCE COSTS
      • Complete unit shore assembly, No need for heavy lift vessels (Jones Act)
      • Reduced weather related dependency
    • ECONOMIC BENEFITS
      • Local employment and economic growth in coastal communities
    • FUTURE PREDICTIONS
      • Industry will continue to chase three variables: higher capacity resource, proximity to load centers and efficiency of production
      • Ultimate goal of project economic efficiency
