Abstract: The present invention relates to an offshore wind turbine on a floating support structure (1) comprising in combination: a main floater (1) comprising a part of substantially cylindrical shape, a concrete circular element (2) having a diameter greater than the diameter of the main floater, providing a stationary mass at the base of the floater and a damper, supplementary permanent ballast (4) arranged at the base of the main floater, dynamic ballast boxes (3) included in the main floater and distributed ringwise on the periphery of the floater.

Abstract: The invention is a container (200) for a system for storing and restoring heat, comprising a vessel including means for injecting and withdrawing a gas to be cooled or reheated. The vessel is limited by a first jacket formed from concrete (203) surrounded by a thermally insulating layer (206), which is surrounded by a steel shell (204). The vessel comprises at least two modules formed from concrete (210) located one above the other and centered to form a first jacket from concrete (203). Each module formed from concrete comprises a volume limited by a side wall formed from concrete (211) and a perforated base formed from concrete (205). The volume contains a fixed bed of particles of a material for the storage and restitution of heat (207).

Abstract: The present invention relates to a floating mounting (1) which includes ballasting means (2) in order to vary the draught of the floating mounting. The floating mounting (1) according to the invention has a depth-variable horizontal cross-section, such that the second moment of area of the cross-section of the floating mounting, at the buoyancy surface (Sd), is higher when the floating mounting is deballasted, compared with the second moment of area of the buoyancy surface of the floating mounting, at the buoyancy surface (Sb), when the floating mounting is ballasted.
