A compacter that includes a compacting roller assembly, borne by a support element. The roller assembly includes a straight central shaft, having a longitudinal axis, and a plurality of compacting rollers, mounted parallel to one another about the central shaft, each compacting roller having a peripheral surface rotating around the central shaft about a roller axis. The longitudinal axis of the central shaft is parallel to the central axis of the support element. Each roller axis is inclined by a nonzero incline angle relative to the longitudinal axis of the central shaft.

Device for compacting a tubular structure, associated installation and method

This endpiece includes at least one end segment of each armor element, an end vault and a cover, the end vault and the cover delimiting between them a chamber for receiving the end segment and a material for filling the receiving chamber, in which the end segment is embedded. The endpiece includes a spacing member positioned so as to internally bear upon the end segments of the armor elements of at least one armor layer. This spacing member defining, on at least one end segment of a armor element of said armor layer, contact areas axially spaced apart along said end segment, the contact areas delimiting between intermediate contact spaces between the filling material and the end segment.

This element includes a plurality of longitudinal carbon fiber filaments () and a polymeric matrix () receiving the filaments () for binding them together, the matrix () forming a ribbon intended to be wound around a longitudinal body of the flexible line. The armor element () includes at least one optical fiber () received in the matrix (), the optical fiber () having an elongation at break of more than 2%, as measured with the ASTM-D 885-03 standard.

Armor element for a flexible line intended to be placed in an expanse of water, and associated flexible line, method and process

An undersea flexible pipe for conveying hydrocarbons, the pipe including from the inside to the outside an inner sealing sheath, at least one ply of traction armors wound about the inner sealing sheath, a deformable holding layer including at least one flexible ribbon or holding band wound about the traction armor ply, and at least one tubular structure surrounding the holding layer, wherein the ribbon includes fiber strands oriented substantially in the longitudinal direction of the ribbon. The ribbon is covered by a reinforcing layer of a polymer material for the deformation resistance of the holding layer.

Flexible pipe for conveying hydrocarbons and having a reinforced maintain layer

A subsea flexible pipe, including an internal sealing sheath (), at least one tensile pressure armor layer () wound around the internal sealing sheath, a retaining layer () having at least one reinforcing strip (), the reinforcing strip having filamentary strands () directed substantially longitudinally. The filamentary strands () having polymer fibers (). The polymer fibers have, at room temperature, an elastic modulus in excess of 55 GPa so that the reinforcing strip is able to prevent radial expansion of the armor layer, when the armor layer experiences radial force; and the polymer fibers furthermore have an elongation at break in excess of 4% such that the reinforcing strip is able to undergo deformation without breaking.

Flexible pipe for conveying hydrocarbons in deep water

An ultra dense composite strip for flexible pipe having armouring formed of longitudinal carbon fibers provided within a thermoplastic or thermosetting matrix in the form of a flat ribbon with a substantially rectangular cross-section, whereof at least one of the surfaces of the strip is reinforced with a film made integral with said surface, over substantially its whole width and over substantially its whole length.
