CANTILEVERED TENSION-LEG STABILIZATION OF BUOYANT WAVE ENERGY CONVERTER OR FLOATING WIND TURBINE BASE

Publication No.: WO2021231102A1 18/11/2021

Applicant:

ROHRER TECH INC [US]

Absstract of: WO2021231102A1

A device to stabilize, reduce, or control the wave or wind-induced heave (vertical), surge (lateral), or pitching (rolling) motion of a floating or semi-submerged buoyant base, raft, barge, buoy or other buoyant body such as the buoyant base of a wave energy converter or a floating wind turbine base. The device concurrently allows the floating base to self-orient or weathervane to substantially maintains its orientation with respect to the direction of oncoming waves, winds, or wind gusts. The device also facilitates maintaining the submerged depth or vertical orientation of the buoyant base relative to the still water line to compensate for tidal depth changes.

CN_112912306_A

Absstract of: US2021355917A1

A method of installing a wind turbine generator onto a floating foundation. The floating foundation has variable buoyancy and is pre-ballasted to float at a predetermined vertical position before installation of a wind turbine generator component onto the floating foundation. A wind turbine generator component supported by lifting equipment is brought towards the floating foundation until contact is made with the floating foundation. Ballast is removed from the floating foundation to increase the buoyancy of the floating foundation such that weight of the wind turbine generator component supported by the floating foundation is increased from substantially zero to substantially the entire weight of the wind turbine generator component. The vertical position of the floating foundation is substantially unchanged during transferring weight of the wind turbine generator component onto the floating foundation.

Applicant:

SEAPLACE S L [ES]

ES_2876053_PA

Absstract of: WO2021224525A1

A solution for a floating reinforced concrete wind power platform for the mass production thereof, characterised by a geometric design endowing the concrete with a natural hydrostatic pre-stress, causing it to function under compaction. The structural response of the platform is improved by working in the most effective manner, and the appearance of fissures or cracks in the concrete is avoided, reducing the permeability thereof, and enabling a smaller quantity of steel rebars in the structure, also increasing the safety during operation. Furthermore, it has a system for anchoring the mooring lines to the structure in the form of a reinforced concrete lattice for the uniform distribution of the mooring tensions, minimising the pre-stress at the higher part of the platform and increasing the shear load area caused by the change in cross-section between the platform and the wind turbine generator tower. The geometric design further confers the versatility of being able to adopt low-draught SPAR-type solutions, semi-submersibles, barges or buoys, with the wind turbine generator installed centrally or off-centre on the structure, thus adapting to different requirements of draught or environmental or logistical requirements.
