Abstract
The present invention provides a novel, floating, offshore wind turbine (FOWT) structure, referred to as a yawing buoy mast (YBM) structure. The YBM platform vertically combines a submerged spar buoy with outrigger legs and a mast on which a wind turbine nacelle is mounted. Compared to a conventional spar buoy wind turbine, weight is significantly reduced by optimizing how loads are borne and reacted by the floating structure. The mass of the YBM platform is reduced relative to the energy captured by the turbine resulting in a reduction in the cost of energy (COE). Platform load dynamics are coupled with the dynamics of the wind turbine by integration of the YBM platform and turbine controllers.
