Abstract: A facility for the subsea disposal of the water produced during deepwater hydrocarbon production, includes a subsea oil/water separation station fed with fluids coming directly from at least one hydrocarbon production well, operating at a pressure independent of and lower than the ambient pressure, and comprising an oil outlet for connecting to a production unit and a water outlet, a flat gravity oil/water separation tank resting on the seabed, continuously fed with water leaving the oil/water separation station, operating at a pressure substantially equal to the ambient pressure, and comprising an oil outlet for connecting to the production unit and a water outlet, and a subsea high-pressure pump connected to the water outlet of the oil/water separation station and to a water inlet of the tank to raise the pressure of the water leaving the oil/water separation station to the ambient pressure before it is admitted into the tank.

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 method of installing and implementing a rigid tube (10) referred to as a “main” tube, wherein the following steps are performed: a) lowering an end of the main tube from a floating support or vessel (13) on the surface (14) to below sea level (14) to be connected to undersea equipment (16) that is immersed (17); and b) maintaining the main tube as immersed in this way for a given period of time. The said main tube (10) is caused to pass through a cylindrical orifice (4) of circular section in a stress limiter device, the orifice having a slippery internal coating (3) secured to a support structure (9) secured to the floating support or vessel, the service tube thus being suitable for sliding in contact against the slippery coating during steps a) and b).
