Abstract: A submarine connection for interconnecting a riser pipe and a flexible pipe (26). The riser pipe has an upper end and the flexible pipe (26) has a lower end (30). A connection assembly includes a rigid fitting having a first limb (64) to be connected to the lower end (30) and a second limb (66) with a connector (67) on the end, and a body (36) having a head (42) and an opposing base (46) provided with an end piece (52) to be mounted on the upper end. The connection assembly also includes first guiding elements (60, 86) secured to the body (36), extending in a position at a distance from the axis of the end piece (52), and second guiding elements (76, 81) secured to the first limb (64), suitable for cooperating with the first guiding elements (60, 86).

Abstract: A method includes providing, around an end section of the pressure sheath, of a crimping ring that is intended to be introduced into the pressure sheath; placing, around the end section and the crimping ring, of an end vault of the end piece, the end vault having an engagement surface for engaging with the crimping ring capable of pushing the crimping ring radially into the pressure sheath; relatively moving of the crimping ring in relation to the engagement surface in order to crimp the crimping ring in the pressure sheath. The method includes, prior to the relative movement, a heating of the end section of the pressure sheath, capable of reducing the Young's modulus of the polymer material of the end section of the pressure sheath and of maintaining a reduced Young's modulus during the relative movement step.

Abstract: A device comprises an assembly for attaching to and moving on the production line. The attachment and movement assembly comprises at least two clamps that can be actuated selectively to clamp the production line, the attachment and movement assembly comprising an active mechanism for moving the clamps longitudinally relative to each other. The attachment and movement assembly comprises a tilting mechanism for tilting the clamps relative to each other, between a position in which they are parallel to each other and a position in which they are tilted with respect to each other. The tilting mechanism comprises a flexion bar capable of switching from a straight configuration in the parallel position of the clamps to a curved configuration in the tilted position of the clamps.
