Wind turbine array

A floating wind turbine array 206, floating windfarm connection architecture (fig.1), or a windfarm, having a subsea power hub 208 which connects a plurality of groups 210 of at least two floating wind turbines 204a, 204b where each group is connected to the subsea power hub by a cable 214 from the first floating wind turbine. Preferably the power cable is dynamic, though it may be a static cable. Multiple subsea power hubs, each power hub being connected to an array (6c, fig.1) of wind turbines, may connect to a subsea transformer (16, fig.1) to form a connection architecture. The subsea power hub may have wet mate (WM, 354a-d, fig.3) connectors or dry mate (DM) connectors and may be filled with oil to compensate for depth related pressure; the connectors are preferably hot-swappable. The output from the subsea power hub is preferably a static 66kV cable fixed to the seabed carrying. The groups of wind turbines are preferably pairs. The stated benefit is reduction in CAPEX and OPEX through ...
