  3. 3. Offshore wind 101• First offshore wind farm – Denmark 1991• 2010 – 39 offshore farms off coasts of UK, Europe, and Scandinavia• Largest turbines now over 500 feet tall• Power carried to land via transmission cable• Wind energy contractors submit site proposals to governing bodies – Contractors provide photomontages

  6. 6. ...and in come the proposalsBureau of Ocean Energy Management(BOEM) reviews all project proposalswithin federal waters • offshore oil and gas exploration • offshore wind • wave • tidal flow • ocean current • environmental laws and regulations
  7. 7. Offshore wind 101 – Cape Wind• Siemens SWT 3.6-107 – rotor diameter – 107m (351ft) – total turbine height – 132m (433ft)• 130 turbines arranged in a grid• 12.5 miles of transmission cable• partial generation planned for 2015
  8. 8. BOEM system requirementsThe system must:• enable spatial design of offshore facility• import geospatial data• allow user control of atmospheric, lighting, wave conditions• generate spatially accurate and realistic visualizations• output reports and images• provide a user-friendly interfaceIt shall enable users to:• evaluate photomontages in environmental impact statements (EISs)• independently assess proposed facilities
  9. 9. ApproachPhotomontages www.capewind.orgPros:• realistic• accepted• accurate* *dependent upon lens usedCons:• need photos from every potential point of interest – oops, we didn’t take a photo from there!• difficult to show different lighting/weather conditions• human error
