Patent ID: 6856036

Claim:
Floating installation for converting kinetic energy of ocean currents in deep waters into electricity utilizing Darrieus type turbine, comprising: a semisubmersible floating platform having: above water level housing, underwater frame, an intermediate frame having at least four vertical hollow columns connecting said above water housing with said underwater frame and forming waterplane when crossing water level; an electric power generator located on said above water level housing, a vertically oriented Darrieus type turbine, at least a pair of said vertical oriented Darries type turbines rotating in opposite direction and incorporated with said underwater frame; a funnel, which is incorporated with said lower frame, has its smaller output opening attached to one side of said turbine and its larger inlet opening facing incoming water stream; means for transmitting torque developed by turbine to electric power generator located on said above water level housing an anchor-mooring system having at least one set of pair of anchors and mooring lines attached symmetrically to lowest part of said underwater frame and at least one set of pair of anchors and mooring lines attached symmetrically to upper parts of said underwater frame; means for transmitting onshore generated electrical power consisting of a flexible power cable, which by one end is attached to lower end of said underwater frame and by other end to an anchor on sea bottom through which it is connected to underwater cable on the sea floor.
