Ships to install offshore wind generators
The European Union has plans to expand electric production by wind turbines up to 20 percent of total production in 2020, Spain being one of the leading countries in installed capacity of such generators located onshore.
Recently they have begun to install wind turbines at sea in areas up to 200 miles offshore and at not excessive depths, outstanding this kind of parks in North Sea countries. These "off-shore" generators solve some of the problems arising onshore, as noise, visual aesthetics, environmental opposition, and they get too a better use of wind power, which is greater at sea than onshore, and also allow for larger power / sizes, with better economic performance.
