Floating TLP wind turbine comprising a buoyancy structure, a plurality of braces, one or more tensioned mooring lines for each brace, and a support structure arranged on the buoyancy structure. The braces extend radially outwardly from a region of the buoyancy structure or support structure, each brace having a distal end portion with respect to the buoyancy structure or support structure. Each distal end portion of the braces comprises a guiding element to allow a guided passage of a tensioned mooring line. Each of the tensioned mooring lines is anchored to the seabed at a first end, and attached/coupled to a region of the buoyancy structure or support structure at a second end, said region being above the region of the buoyancy structure or support structure from which the braces extend radially outwardly. Each tensioned mooring line is guided by the guiding element of the corresponding brace.

This comprises a submerged portion existing below a sea surface, an emerged portion existing above the sea surface, and a partially submerged wave power transfer mechanism portion including the sea surface and coupling the submerged portion and the emerged portion.

A method for installing an offshore wind power generation floating body may include manufacturing a lower structure including a damping plate, a guide beam including protruding portions, and a slot, coupling a temporary buoyancy tank to each protruding portion, installing a concrete block mounting structure in the slot, transporting the lower structure on the sea until a destination by a towing vessel, fixing the lower structure between a first work barge and a second work barge by a link bridge connected to each of the first work barge and the second work barge, and seating a concrete block connected to a second wire of a second crane seated on the second work barge on the concrete block mounting structure in a state in which first wires of a first crane are connected to the lower structure to maintain a tension equal to or greater than a set magnitude.

A floating buoy includes a buoy hull having a tower that extends outwardly from the hull. A plurality of sensors are mounted either on the buoy hull, within the buoy hull, and/or on the tower. The plurality of sensors includes at least one met-ocean sensor, at least one ecological sensor, and at least one wind speed measurement sensor. The floating buoy further includes an autonomous power system that is configured to provide electrical power to each of the plurality of sensors. The wind speed measurement sensor may be a Light Detection and Ranging (LiDAR) wind speed measurement sensor, a surface level wind speed sensor, an ultrasonic wind speed sensor, or SODAR.

Foundation systems and methods using in-situ shaped pile-anchors that are particularly adapted for use in aquatic environments. The shaped pile-anchor of the invented foundation includes a concrete filled tubular metal casing, the bottom end of which is positioned at a predetermined depth in the ground (e.g., aquatic-floor soil) and the top end of which protrudes above the water or soil surface. Concrete fills the inside the metal casing, substantially all the way to the top end of the casing, forming an upper portion of a concrete column. The lower portion of the concrete column extends down below the bottom end of the metal casing and further into the ground. The lower portion is shaped to have a cross-section greater than the cross-section of the upper portion, which equals to the inner diameter of the tubular metal casing. A platform is coupled to one of more of the shaped pile-anchors to support a structure above.

Disclosed embodiments relate to systems and methods for mating a wind turbine off-shore to a spar buoy without the use of a crane barge. The system may include a spar buoy, wherein the spar buoy is secured to a foundation, and a wind turbine to be installed on the spar buoy. The system may also include a first truss affixed to the top of the spar buoy and a second truss affixed to the bottom of the wind turbine. The first truss may comprise either stabbings or receptacles configured for mating to the second truss and the second truss may comprise either receptacles or stabbings configured for mating to the first truss.

Disclosed are a semi-submersible raft wind power generation unit and a construction method therefor. The raft wind power generation unit includes at least three floaters (12) and at least three wind turbines (21) configured to be placed on the floaters (12). The raft is configured to turn about a vertical axis and be fixed to a seabed (2) by a mooring line (36). A force resultant from an incoming wind load passes closely around the center of geometry of the raft, which is a distance away from the center of rotation of the raft so that a yaw moment about the center of rotation is created that rotates the raft until the force resultant passes through the center of geometry and center of rotation

An offshore power generating system has a buoyancy body shaped as a hull with a bow and aft end, and elongated mast extending up from the buoyancy body to the buoyancy body about a horizontal transverse axis. A rotor is supported in one end of the longitudinal mast for rotation about a horizontal axis. The buoyancy body is kept in position with the bow turning up into wind and incoming waves. Rotational support of the mast has a horizontal rotational axis through the center of gravity of the mast that lies in the center plane of the buoyancy body above the aft end when the buoyancy body lies in operational position in calm sea with the rotational axis of the rotational support of the mast orthogonal to the center plane of the buoyancy body. A method for on-board loading and commissioning of mast with installed rotor on-board a buoyancy body.

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.
