• Wind Power Moves into Deep Waters (http://www.technologyreview.com/Energy/20854/?nlid=1124) - A floating wind turbine is planned for 10 kilometers off Norway. (MIT Technology Review; June 4, 2008)

• Technip wins contract to build world's first full-scale bobbing wind turbine (http://www.forbes.com/afxnewslimited/feeds/afx/2008/05/22/afx5038319.html) - Technip has been awarded by StatoilHydro an engineering, procurement, construction and installation contract for the Hywind project substructure wind turbine which will be located offshore Karmøy, Norway, at a water depth of 200-220 meter, with peak production capacity of 2.3 MW. (Forbes; May 22, 2008) (Press Release (http://www.businesswire.com/portal/site/home/email/headlines/?ndmViewId=news_view&newsLang=en&div=428291328&newsId=20080522005399))

• World's first floating wind farm to be built in North Sea (http://environment.independent.co.uk/lifestyle/article2714191.ece) - Siemens has teamed up with a Norwegian energy group, Norsk Hydro, to install a wind farm in the middle of the North Sea, beginning with one test unit in under two years, ending with 200 turbines by 2014. The turbines would access the strong off-shore winds, and would not be visible from land. (The Independent; UK; June 27, 2007)
  

• Floating Wind Turbines (http://pesn.com/2005/11/03/9600200_NorskHydro_deep-off-shore-wind/) - Captures off-shore winds, while sparing expense of footing. Norwegian utility expects production prototype in 2007. (PESN; Nov. 3, 2005)
  

MIT

• Deep-sea oil rigs inspire MIT designs for giant wind turbines (http://pesn.com/2006/09/20/9500238_MIT_floating_wind_turbines/) - Oil rig floatation technology adapted for off-shore wind turbines, enabling deployment in the higher winds, and out of view of the on-shore horizon. (PESN; Sept. 22, 2006)
  

Stansbury Resources

• Floating offshore wind energy and hydrogen fuel generating company tipping to Europe or Asia (http://pesn.com/2005/10/31/9600198_Offshore_Wind_Hydrogen/) - Inventor Tom L. Lee, Ph.D. has developed a floating wind turbine platform concept for accessing the higher winds out at sea, and converting wind energy efficiently to hydrogen and electricity. Would prefer to license its manufacture and distribution to a U.S. party. (PESN; Oct. 31, 2006)

Platforms

• VersaBuoy Sea Platforms (http://www.vbuoy.com/thesystem-applications.html) - New system is 1/2 the cost of existing deepwater oil platforms; and is modular, opening many new possibilities, including off-shore wind and wave energy harnessing.
  

Blue H

• Offshore Wind at an Affordable Price (http://www.ecogeek.org/content/view/1203/) - Blue H (http://www.bluehgroup.com/index.php) Submerged Deepwater Platform technology is adapted from floating platforms developed by the oil industry, to support a tower and a wind turbine. Their wind farms would be so far from shore as to be virtually invisible, where the winds are stronger and are more constant. (EcoGeek; Dec. 6, 2007)
  

Sway

• Deep-Water Wind: Out of Sight (http://www.ecogeek.org/content/view/1397/) - Sway (http://www.sway.no/) is developing a deepwater system that will allow turbines to be situated farther out to sea where winds can be steadier and stronger, hidden from all save a few passing ships. It is based on a floating elongated pole extending far below the water surface with ballast at the bottom part. (EcoGeek; Feb. 25, 2008)
  

Off-Shore, Near Shore

• Offshore Wind (http://www.freeenergynews.com/Directory/Wind) - Winds are stronger and more stable; economy of scale.
  

• Off-shore 5M Wind Turbine Premier (http://pesn.com/2006/08/30/9500231_North_Sea_offshore_5M_wind_turbine/) - REpower Systems' five-megawatt turbine, the largest ever off-shore, is piled to the seabed at a record depth of 44 meters. (PESN; Aug. 30, 2006)
  

• Gulf Coast oil equipment repurposed to build first US offshore wind farm (http://www.wired.com/wired/archive/15.02/wind.html) - Wind Energy Systems Technology (WEST) is building the first offshore wind farm in the US off the coast of Galveston, Texas, using wind turbines mounted on oil drilling platforms. A test turbine is scheduled to be in operation this summer; the other 50 will produce 150 megawatts by late 2008. (Wired; February 2007)
  

• WindHunter (http://www.windhunter.org/) - Hydrogen can be produced by wind turbines and electrolysers on the proposed WindHunter vessels. These ocean going ships will operate out of sight of land either anchored or free floating while facing into the wind and the oncoming waves.
  

• ecoPowerUSA (http://www.ecopowerusa.com/index.html) - Develops, sells, installs, operates, and services Floating-Windfarms-at-Sea™, using floating vertical axis wind turbines (“Floating-VAWTs™‿) – to generate ‘green’ electricity at low costs from strong wind at sea!
  

• Offshore Wind Turbine Farms: Ambitious and Beautiful (http://thrillingwonder.blogspot.com/2007/01/wind-power-in-stormy-waters.html) - Blog entry with several good pictures of an offshore wind farm under construction, as well as some failed turbine structures.
