Floating Wind Turbines
100 meters beneath the sea's surface
Can be employed at ocean depths of 120 to 700 meters
Main objective is to test the impact of wind and waves on the structure over a two-year
period
Initiatives Blue H
Dutch company Blue H Technologies has devised a `Submerged Deepwater Platform'
(SDP)
In 2008, the company installed a 75% scale prototype SDP with a small wind turbine in
113-metre deep water
20 km off the coast of Southern Italy
After 6 monts at sea, the unit was decommisioned early on 2009
Target goal are units in water depths of 70-300 meters

Conclusion
Shallow-water turbines cost between 2.4 and 3 million United States dollars per
megawatt to install, according to the World Energy Council.
The main reason to develop FWT is the possibility to harness wind energy far off the
coast-line, which in return gives greater energy output and less visual/noise pollution.
