Titolo: Progetto di eolico galleggiante francese nel Mediterraneo

(...) The installation will include 3 to 6 wind turbines of a minimum of 6
MW each. They will be joined with an integrated semi-submersible type
floating foundation proposed by Eiffage Métal. The concept developed by
Principle Power in its Aix-en-Provence engineering center represents the
most promising technology on the market today and has been tested off the
coast of Portugal since 2011. Eiffage Métal will manufacture and install
the floats.
 
Armed with significant innovations, the project constitutes a decisive
phase that anticipates the floating turbine sector’s industrialization in
France and abroad. Indeed, the promising floating turbine technology offers
the advantage of being installed in areas of high winds and in deep seas
far from the coastline. The Mediterranean coastal areas of France are
highly favorable to the development of this seaborne renewable energy. With
this call for tenders, France joins Japan, Norway, Portugal and the United
Kingdom, which have already embarked upon this technology. (...)

Sembra una tecnologia interessante. Si dice che tale sistema costi meno di
quello tradizionale per l'eolico marino, anche se non ho dati in proposito.
Può darsi che in realtà sia conveniente solo dove ci sono fondali profondi.

Probabilmente il primo parco eolico galleggiante ad essere costruito sarà
però questo in Scozia:

(...) Statoil will install a 30 MW wind turbine farm on floating structures
at Buchan Deep, 25 km offshore Peterhead, harnessing Scottish wind
resources to provide renewable energy to the mainland. The wind farm will
power around 20,000 households. Production start is expected in late 2017.
(...)
The pilot park will cover around 4 square kilometres, at a water depth of
95-120 metres. The average wind speed in this area of the North Sea is
around 10 metres per second.
(...)
Offshore wind already has a strong foothold in Europe with 10 GW installed
capacity, and a global potential to reach more than 100 GW by 2030. With
fixed turbines, offshore wind is optimal for 20-50 metres water depth. With
floating structures, further expansion will be enabled in new deep-water
areas around the world.

 Ma che venti ci sono in Mediterraneo?
 
Secondo l'Atlante eolico dell'RSE
http://atlanteeolico.rse-web.it/
 
nel mezzo del mediterraneo si arriva a 10 m/s a 100 m di altezza, quindi la
stessa velocità indicata per l'impianto in Scozia. Però bisogna
allontanarsi parecchio dalla costa oppure andare in Sardegna.
 
Sulle coste indicate per l'impianto francese presumo che la produttività
sia la stessa del mar ligure nel tratto più vicino alla costa, quindi 7 m/s
sempre a 100 m di altezza. Può darsi però che il Golfo del Leone sia più
ventoso.
