Abstract: A pipe (10) including an inner corrugated tube (16) having an axis A-A?, defining a plurality of corrugations (30) leading radially towards the axis (A-A?) and at least one tensile armor layer (18), arranged around the corrugated tube (16). It includes at least one thermal insulation layer (44, 46), arranged around the armor layer (18). The pipe (10) comprises an inner sheath (14) for guiding the flow of cryogenic fluid arranged in the corrugated tube (16), the inner sheath (14) being made up of a plurality of cylindrical segments (50). Each cylindrical segment (50) of the inner sheath (14) covers a plurality of successive corrugations (30) of the corrugated tube (16) and includes an outer abutment (54) for axial wedging received in a corrugation (30) of the corrugated tube (16).

Abstract: A filling platform connected to a ship, and at least one manifold which opens onto the platform. A detachable tubular connector connects the manifold to a fluid delivery hose carried by a delivery installation. At least one carriage conveys the connector over the platform. The carriage is moveable across the platform to convey the tubular connector over the platform between a storage position and an active position, in which latter position, the connector is fixed to the manifold. The system is applicable to the transfer of liquefied natural gas from offshore storage installations to tanker ships.

Abstract: A device including a plurality of disconnected ballast elements (24) for a pipe (16). Each ballast element (24) has a lower surface (34) to be laid at the bottom (12) of a body of water (14) and an upper surface (32) delimiting at least one concave trough (38) for supporting the pipe (16A, 16B). A top cover (26) for protecting the pipe and connecting at least two disconnected ballast elements (24) so as to cover the pipe (16A, 16B) between the ballast elements (24). The cover (26) extends opposite the trough (38) and delimits, together with the upper surfaces (32) of each ballast element (24), a passage for receiving the pipe (16A, 16B).

Abstract: This installation comprises a transport conduit which is at least partially submerged in a body of water, a device for conveying fluid between the vessel and the conduit, and a floating platform for securing the vessel. The platform comprises a carrier structure which is partially submerged in the body of water. The carrier structure comprises an open-work trellis which delimits internal spaces which are for circulation of water and which open in the body of water. The floating platform further comprises flexible lines for anchoring the carrier structure to the bottom of the body of water. The ratio of the volume of the internal spaces to the total of the volume of the open-work trellis and the volume of the internal spaces is greater than 0.9.

Abstract: The present disclosure comprises a platform and a manifold, the latter being intended to be connected to a fluid tank. The manifold comprises a length of rigid tube defining a pipe of approximately horizontal axis and a length of connecting tube for connection to a transfer line connected to the length of rigid tube. The length of connecting tube is permanently attached to the length of rigid tube and is hinged to the length of rigid tube to allow movement relative to the length of rigid tube between: —a retracted rest position in which the length of connecting tube extends entirely inside the inner edge; and —a first or filling position, in which the free end of the length of connecting tube projects out from the outer edge of the support platform.

Abstract: A device for conveying a substance that comprises: a first duct for containing the substance; an optical fiber connected to the first duct and extending along the duct, the optical fiber including several detection members spaced along its length, each detection member having a separate reflection spectrum that varies with the presence of the substance to be detected; a control device including a light source capable of emitting a light in the reflection spectrum of each detection member, a light receiver capable of detecting the light amplitude in the detection spectrum of each detection member, and an analysis module capable of determining the presence of a leak of the substance based on the light amplitude provided by the light receiver.

Abstract: A method and an installation for connecting a rigid submarine pipe and a flexible submarine pipe. The rigid pipe terminates in a free connection end. The flexible pipe has a flow-line portion and a suspended portion. The flow-line portion has an input end connected to the free connection end. The installation comprises an anchoring device to hold the flow-line portion anchored at an anchor point and to allow the flow-line portion to form an undulation. The anchoring device is suitable for holding the anchor point at a distance and close to the free connection end to form the undulation between the anchor point and the free connection end.
