Abstract: A floating support structure for an offshore wind turbine, comprises a float intended to be partly immersed and on which a wind turbine mast is intended to be assembled, and a counterweight connected to the float and intended to be immersed under the float. The float comprises a toroid or polygon-shaped main structure with at least five sides, a central tubular structure having a diameter adapted to receive the mast of the wind turbine and comprising a section able to be ballasted in order to adjust the waterline of the float, a first series of horizontal struts distributed about a vertical axis and connecting the main structure to the central structure, and a second series of oblique struts distributed about a vertical axis and connecting the main structure to the central structure at an angle comprised between 15° and 60° with the horizontal struts.

Abstract: A device for rapidly remotely coupling together two vessels, in particular a first ship or floating support and a second ship, comprises: at least one floating and docking structure fastened to or suitable for being releasably fastened to the side and/or the keel of the hull of a second vessel; and at least two actuators spaced in succession from one another in the longitudinal direction of the first vessel. The actuator cylinder of each the actuator is arranged to be fastened to the side of the hull of the first vessel, using a first fastener and pivot hinge device. The end of the rod of each actuator is arranged to be fastened to or suitable for being fastened to the floating and docking structure via a second fastener and pivot hinge device.
