A hull for a semi-submersible wind turbine platform capable of floating on a body of water and supporting a wind turbine includes a keystone and at least three bottom beams extending radially outward of the keystone. Each bottom beam has a primary beam portion and a column base portion, wherein the column base portion is configured to support an outer column of the hull thereon, and wherein the primary beam portion defines a first ballast compartment therein. The first ballast compartment is in fluid communication with water in the body of water in which the hull is floating.

The present invention relates to methods, apparatus and computer program products for coordinating the control of a floating wind turbine (101) between a wind turbine controller (111) and a platform controller (110). One or more wind turbine control systems and/or one or more platform control systems may be altered based on said coordinated control of said floating wind turbine (101).

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. The floating wind turbine platform also includes three truss members, each truss member including two chord members and two diagonal 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.

The present invention provides a marine structure platform including: horizontal connecting parts which are disposed under the seawater and connected to one another in a lattice structure; vertical connecting parts which are installed uprightly at four corners of the horizontal connecting parts and protrude from the seawater; and movement damping parts which are extended at the four corners from the vertical connecting parts along the horizontal connecting parts adjacent to one another, the movement damping parts having a plate shape so as to define a vertical gap therebetween.

Floating support for a wind turbine including a central support member, and at least three buoyancy assemblies, each connected to the central support member via a radial connector beam and mutually interconnected via a transverse connector beam, wherein each buoyancy assembly includes a connector body having two radial sides, an outward and an inward transverse side, wherein two transverse connector beams and a radial connector beam extend away from the inward transverse side of the connector body, an anchor is provided at or near the outward transverse side of the connector body and the radial sides of the connector body are each connected to a respective buoyancy element.

The present invention relates generally to underwater wings for providing lift to boats. More particularly, the invention comprises an underwater wing that attaches to the hull or hulls of a pontoon or tri-toon boat. The purpose of the wing is to provide a designated amount of lift to reduce drag and improve performance of the watercraft. This is different from a traditional hydrofoil, which is designed to lift a boat completely out of the water.

The disclosure relates to a floating wind turbine platform, comprising: a substantially triangular hull configurable to support a wind turbine tower; the hull comprising a first, second and third column, the first, second and third columns being connected by a first, second and third pontoon member, as well as by a first, second and third connector.

The invention relates to a crane for assembly and installation of offshore wind turbines on an offshore location, to a vessel for assembly and installation of offshore wind turbines on an offshore location, and to a method for assembly and installation of offshore wind turbines on an offshore location. According to the invention the crane is provided with a base section and a top section, wherein the top section is rotatable supported by a bearing, and can be rotated with the wind turbine hoisting device relative to the base section about a vertical axis, wherein a first trolley guide is mounted to a top section of the installation crane for guiding a vertically mobile wind turbine supporting trolley. According to the invention the vessel is provided with one or more assembly stations on different sides of the installation crane.

A support structure for a wind power generation device comprises: a plurality of floats that can float on the surface of water or in the water; a connecting member having one end connected to one of the floats and the other end connected to another of the floats among the plurality of floats; a support platform that is provided between the plurality of floats and supports the bottom end of a tower part of the wind power generation device; a linear wire member having one end connected to one of the floats and the other end connected to the support platform; and a support member that is provided on the floats or on the connecting member and supports the tower part, which is supported on the support platform, from a lateral direction while the support member being movable along the axial direction of the tower part.
