  1. 1. Washington State Ocean Energy Conference - Offshore Wind Overview by: William L. Hurley, Jr. P.E. November 9, 20111
  2. 2. Presentation Topics 1. Introduction 2. Overview of a Wind Farm Installation Project 3. Puget Sound Infrastructure 4. Various Floating Wind Turbine Concepts2
  3. 3. The Glosten AssociatesGlosten has a staff of 70 Associates,consulting in many marine industry sectors: • Oceanographic Research • Aerospace and Special Projects • Infrastructure • Energy, Oil and Gas • Commercial Shipping • Passenger Transportation • Renewable Energy (Offshore Wind) • Government Projects in Commercial Yards
  4. 4. Glosten Position in IndustryFloating Tension-LegTurbine PlatformWe have advanced thetechnology of our TLTPand are now promotingworld wide.4
  5. 5. 5
  6. 6. 6
  7. 7. Washington State Assets and Infrastructure 1. History of Innovative, Major Offshore and Marine Construction Projects • Sealifts in 1970’s and 80’s supported Prudhoe Bay Development and Alaska Pipeline Construction • Floating Bridges (new 520 bridge underway) • Tacoma Narrows Bridge – Cassion Installation 2. Major Marine Construction Firms with Equipment Based in Puget Sound • Manson Construction • Kiewit General • Cable Laying 3. Many Shipyards and Fabricators with Large Steel Through-put Capability, Supported by7 Strong Engineering Firms
  8. 8. Washington State Assets and Infrastructure 4. Oceanographic Research Support • U/W School of Oceanography and R/V Thompson • U/W Applied Physics Lab (APL) 5. Materials Transportation Infrastructure Strong • Tug and Barge Companies (Foss and Crowley plus many more) • Rail Access to Waterfront Loading (Boeing Mukilteo example) 6. Fabrication, Assembly and Staging Areas Plentiful (no water depth or air draft limitations) • Grays Harbor • Port Angeles8
  9. 9. Floating Foundation Stabilizing Methods
  10. 10. Statoil HyWind Spar
  11. 11. WindFloat Semisub, Sway Spar, GlostenPelaStar
  12. 12. Blue H Tension Leg PlatformPhase III
  13. 13. Windsea and Nautica Windpower
  14. 14. NOVA (Novel Vertical Axis)
  15. 15. Development Stages Research to Prove Feasibility • TRL 2 = concept development • TRL 3 = simulation Technology Development • TRL 4 = basic model testing • TRL 5 = complete model test program Technology Demonstration • TRL 6 = intermediate-scale prototype deployed offshore System Commissioning • TRL 7 = full-scale prototype deployed offshore (“Relevant Environment”) • TRL 8 = full-scale prototype deployed15 offshore (“Expected Environment”)
  16. 16. Closing Remarks Floating Offshore Wind is Viable • Within 5 years we will see 4 full- scale demonstration projects • Cost of Energy will be driven down with technology developments • There will be a few platforms with acceptable technology, each with advantages that suit different sites/turbines European & Asian Initiatives will Develop Technology When Washington State is ready for Offshore Wind, Floating16 Technology will be ready to apply
