    Abstract: L'invention concerne une structure tubulaire en béton.
    La structure est essentiellement constituée par des tubes principaux creux (TP) assemblés par des tubes secondaires pleins ou creux (TS), l'assemblage étant assuré par des câbles de précontrainte (C) des tubes secondaires qui traversent les tubes principaux en passant dans l'épaisseur de la paroi des tubes principaux sans pénétrer dans les creux des tubes principaux, selon des courbes de passage compatibles avec la fonction de ces câbles.
    L'invention s'applique notamment à la constitution des structures en mer.

    Abstract: The present invention relates to a reinforced undersea unit pipe element (1) suitable for being laid empty at great depth. The element includes a tubular wall, having at least one external peripheral reinforcing element (6, 7) creating a plurality of localized zones on the outside surface of the wall, the radial distance (d1) between the outside surface of the pipe and the longitudinal axis (XX') of the wall in the zones being greater than the outside radius (R) of the tubular wall portions lying between the successive zones in the longitudinal direction (XX'), two successive ones of the zones being spaced apart in the longitudinal direction (XX') of the tubular wall by a distance (D) equal to ½ to 4 times the outside diameter (d) of the tubular wall portions, the successive zones preferably being spaced apart regularly.

    Abstract: Material with adjustable buoyancy, which comprises solid particles dispersed in a binder, which binder is quasi incompressible and has a density less than water and preferably less than 0.95 and has liquid/solid phase change temperature (T0) greater than that of the surrounding aqueous medium and the solid particles have a density less than that of the binder. INDEPENDENT claims are also included for: (i) a float with adjustable buoyancy, especially for major applications, which comprises material (M); (ii) a process for producing material (M) in a liquid form where the solid particles are mixed with the binder.

    Abstract: A device for thermally insulating at least one undersea pipe. The device comprises a thermally insulating covering surrounding the pipe, the covering being covered by an outer leak proof protective case, and the case being made of a flexible or semi rigid material suitable for remaining in contact with the outside surface of the insulating covering when it deforms. The device is characterized in that the insulating covering comprises a phase-change material confined in at least one container made of a flexible or semi rigid material that is deformable, and the container is disposed around the pipe.

    Abstract: The present invention relates to a guide device for an off-shore drilling installation comprising at least one drilling riser extending from a floating support to a said guide device at the sea bottom, said drilling being performable from said floating support via said drilling riser using a drill string fitted at its end with drilling tools. According to the invention, said telescopic guide device comprises a telescopic guide pipe comprising coaxial telescopic pipe elements about an axis, the smallest-diameter innermost telescopic pipe element being fitted at its end for breaking up the ground suitable for progressively burying said telescopic guide pipe in the ground so as to enable a drilling tool to be guided more deeply into the ground.
