Floating offshore wind turbine system, apparatus and method
A floating offshore wind turbine includes a rotor and a generator turned by the rotor. An elongated buoyant body supports a tower that supports the generator and rotor. The buoyant body or the tower may support aerodynamic features to counteract heeling forces or to steer the floating wind turbine as it swings on its anchor line. The floating offshore wind turbine may be configured to move the anchor line force vector to counteract heeling forces. A control system may control the aerodynamic features and the movement of the anchor line force vector.
Circuits for electricity-generating units
A system receives locations of a plurality of electricity-generating units in an area, and it divides the area into a plurality of sectors. The system traverses through the sectors and forms a set of sectors. The set of sectors includes a set of electricity-generating units. The set of electricity-generating units does not exceed an aggregate voltage threshold. The system forms a circuit with the set of electricity-generating units by determining a shortest path to connect the set of electricity-generating units. The system adjusts this shortest path to incorporate environmental and physical constraints.

Wind turbine blade comprising a bulkhead
This invention relates to a method of manufacturing a bulkhead unit, a method of installing a bulkhead unit, a bulkhead, a bulkhead unit and a wind turbine blade. The bulkhead is manufactured by vacuum forming or rotational moulding and has a set of predetermined openings formed during manufacturing. Various additional elements are pre-mounted or pre-integrated into the bulkhead before installation of the bulkhead unit. This pre-assembled unit can then be positioned inside the blade root section and connected to the blade section.

Method for installing a jointed rotor blade of a wind turbine
A method is provided for installing a jointed rotor blade of a wind turbine. A second section is positioned in a six o'clock position. At least one lifting line is routed through the second section radially inward of an inner surface of the section. A first end of the lifting line is coupled to a first section and a second end of the lifting line is coupled to a power source positioned within at least one of a or a nacelle of the wind turbine. The first section of the jointed rotor blade is lifted toward the second section by driving the lifting line via the power source. The first section and the second section are lined gather at a chordwise joint and coupled at the chordwise joint.
