The present invention relates to an offshore wind turbine on a floating support structure () comprising in combination: a main floater () comprising a part of substantially cylindrical shape, a concrete circular element () 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 () arranged at the base of the main floater, dynamic ballast boxes () included in the main floater and distributed ringwise on the periphery of the floater.

The present invention relates to a floating mounting () which includes ballasting means () in order to vary the draught of the floating mounting. The floating mounting () 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.

The invention relates to anchoring systems for floating bases for the production of energy at sea (floating wind turbine, wave energy, floating hydraulic turbines, ETM platform, etc.) and/or for petroleum exploitation at sea, constituted by at least one anchoring line which comprises at least one portion which is constituted by cable, chain or a combination of the two and at least one elastic device.

A wind power system includes a wind turbine resting on a floating support and an anchoring system for anchoring the wind power system connected to the wind power system by attachment points. The wind power system has the attachment points raised above the waterline of the floating support to a height with respect to the waterline determined so as to counterbalance an overturning moment of the wind turbine subjected to a given wind speed.

The hoop winding method allows to manufacture a reinforced tube by carrying out the following operations: The fact that the two enclosures Zand Zare distinct and independent allows pressures Pand Pto be applied independently of one another. Thus, the method allows independent radial and axial prestresses to be applied so as to optimize the strength of the hoop-wound tube.

Hoop winding method for reinforcing the axial strength and the internal pressure strength of a tube

The invention relates to a pipe element comprising at least one hoop-wound tube (T), the hoop-wound tube (T) comprising a central part consisting of a metal core (A) covered by at least one hoop layer (F), at least one connecting part(C). Hoop-wound tube (T) also comprises at least one transition element (B) welded, on one side, to one end of the core (A) and, on the other side, to one end of connecting part (C). This pipe element can be used as an auxiliary line of a drilling riser pipe.
