Abstract: The present invention relates to a method and a wind turbine structure for optimising the weight of the wind turbine and the offshore foundation. The wind turbine is operated based on the measured wave height which in turn allows the tower height to be reduced so that the ratio between the tower height and the length of the wind turbine blades is greater than 0.5. The rotor is parked in a predetermined position with a maximum or minimum clearance between the tip end of the wind turbine blades and the sea level if the measured wave height exceeds a predetermined threshold. A monitoring unit arranged relative to the wind turbine detects if one or more objects are located within a monitoring area. If an object is located within the monitoring area, the wind turbine is shut down and the rotor is rotated to the parked position.

Abstract: A structure of a floating, semi-submersible wind turbine platform is provided. The floating wind turbine platform includes three elongate stabilizing columns, each having a top end, a keel end, and an outer shell containing an inner shaft. Each stabilizing column further includes a water entrapment plate at its keel cantilevered in a plane perpendicular to a longitudinal axis of the stabilizing column. The floating wind turbine platform also includes three truss members, each truss member including two horizontal main tubular members and two diagonal tubular members. The truss members connect the stabilizing columns to form a triangular cross-section. An elongate wind turbine tower is disposed over the top end of one of the three stabilizing columns such that the longitudinal axis of the tower is substantially parallel to the longitudinal axis of the stabilizing column.

Abstract: Wave energy conversion systems are provided utilizing a mass of water entrained in a collapsible water mass enclosure that is suspended beneath a float (e.g., a vehicle, buoy, platform, etc.) to provide an inertial force in opposition to the rising heave-induced acceleration of the float. The water mass enclosure is communication with a generator, such as by tethering one end of a tethering means to the generator and the other to the enclosure. The enclosure may be placed in communication with an intermediary hydraulic system, which is also in communication with the generator. In certain embodiments, the system will include a reel system for deploying and retrieving the water masse enclosure.

Abstract: An apparatus for supporting an additional structure near a surface of a body of water, and a system which includes the apparatus and further includes the structure attached to the apparatus. The apparatus and the system are each configured to assume a rest position and orientation when the apparatus or system is floating at the surface and when the body of water is substantially still, where the rest orientation defines a vertical direction extending from the surface to a keel at a lowermost position of the apparatus. The apparatus includes a support member, which, in use, is attached to the additional structure; and buoyant units. Each buoyant unit is attached to the support member at or near the keel and extends from the keel in a longitudinal direction of the buoyant unit, which longitudinal direction defines an angle of approximately 35°-65° with respect to the vertical direction.

Abstract: A mechanism to provide controlled variable area blades for fluid driven tangential turbines is disclosed, where the spindle axis is perpendicular to the fluid flow, applicable in vertical axis hydraulic turbines but extensive to horizontal axis or wind turbines, with the rotor completely immersed on the flow. Each blade varying its area at selected position of the rotor turning, increasing to maximize conversion of the kinetic energy of the fluid onto mechanical rotational power of the shaft, or reducing to minimize drag moving opposed to such current. A comprehensive method is provided to control the variation in area for any specific degree of rotation of the turbine shaft on a rotational blade array, different flow conditioning deflector solutions in order to increase the power generation capability of the turbine, by increasing speed of the incoming flow to the rotor and minimizing drag of the returning blades.

Abstract: A wave energy absorption device comprises a buoy adapted to move with movements of water, and a buoy oscillation device attached to the buoy, the buoy oscillation device comprising an elongated means and a rotary means adapted to interact with the elongated means. A hydraulic pump with variable displacement is connected to the rotary means and connectable to a hydraulic circuit. When the buoy moves with movements of water, relative movement is created between the elongated means and the rotary means, whereby the hydraulic pump transforms kinetic energy into hydraulic energy which to the hydraulic hose, and whereby a torque is applied to the rotary means by the hydraulic pump to dampen or amplify the movements of the buoy. The buoy oscillation device provides individual control of the force applied to the buoy by change of displacement in the hydraulic pump.
