A FLOATING SUBSTRUCTURE FOR OFFSHORE WIND TURBINES

Resumen de: WO2026120598A1

A floating substructure for supporting an offshore wind turbine includes a plurality of buoys arranged in a ring configuration and interconnected by articulating joints. A central column is positioned within the ring and is configured to receive and support a distal portion of a turbine tower. A plurality of first slings extends from a proximal region of the central column to corresponding articulating joints, and a plurality of second slings extends from a distal region of the central column to corresponding articulating joints. A plurality of anchors is positioned to anchor the substructure, and a plurality of third slings connects the anchors to the respective articulating joints. The arrangement of buoys, articulating joints, and sling systems provides a tension-based support structure suitable for deep-water offshore wind applications.

NEW FIVE-COLUMN SEMI-SUBMERSIBLE WIND TURBINE FOUNDATION AND MOORING SYSTEM THEREOF

Resumen de: WO2026119212A1

Provided in the present invention are a new five-column semi-submersible wind turbine foundation and a mooring system thereof. The new five-column semi-submersible wind turbine foundation comprises an X-floater, wherein the X-floater is provided with a side column at each of the four ends thereof and is provided with a central column at the center, and the four side columns are centrosymmetrically distributed with respect to the central column; a tower is provided on the central column, a wind turbine generator system is provided at the top end of the tower, and the wind turbine generator system converts wind energy into electric energy; and an external platform is further provided on the outer peripheral surface of the junction between the central column and the tower. In the present invention, the number of side columns that provide stability is increased from three to four with respect to the prior art, which increases the moment of inertia of a waterplane by approximately 50% under the condition that the area of the waterplane remains unchanged; the stress on the structure is all transferred to the X-floater, thereby reducing the center of gravity of the structure; moreover, the communication between the side columns and the central column is realized by means of a design in which a deck passage and the external platform are staggered in terms of elevation, thereby ensuring subsequent operation and maintenance; and finally, "8x1" distributed mooring is proposed to replace

APPARATUS AND ASSOCIATED METHODS

Resumen de: WO2025026978A1

A method of providing a buoyant concrete support structure (10) for an offshore installation, such as a wind turbine. A monolithic multicellular concrete member (11) is formed with at least five cells (14) arranged circumferentially around a central vertical longitudinal axis (20). The diameter of each cell (14) is smaller than a diameter of a circumference along which the cells (14) are arranged. The cells (14) are formed as vertically-extending hollow elements with an enclosed bottom portion provided below a hollow central void (15) thereabove. The cells (14) are formed contemporaneously such that all of the cells (14) are integrally-formed with each other in unison to provide the seamless monolithic multicellular concrete member (11). The cells (14) are coherent such that each cell (14) shares a common wall portion (40) with an adjacent cell (14).
