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 deflector (38) including: a support (70); an intermediate member (72), pivotally mounted in the support (70) around a first rotation axis (B-B′); at least a secondary pivoting member (74), pivotally connected to the intermediate member (72) around a second rotation axis (C-C′) parallel to the first rotation axis (B-B′); for each secondary pivoting member (74), at least a pair of rotating members (76). Each rotating member (76) is connected to the secondary pivoting member (74). The deflector (38) including: a guiding mechanism, for guiding each rotating member (76) in translation with regard to the support (70) along a translation axis (D-D′) non parallel to the first rotation axis (B-B′); a connecting member (78), pivotally mounted to the secondary pivoting member (74). The rotating member (76) is rotatably mounted on the connecting member (78) around a rotating member rotation axis (E-E′).

Abstract: A method of installing an In-Line Structure (ILS) to a flooding fluid-filled pipeline extending from a reel, over an aligner, and through a lay-tower during offshore reeling, the pipeline having an oblique part from the reel to the aligner, and a vertical part from the aligner through the lay-tower, including the steps of: (a) draining the flooding fluid from the vertical part of the pipeline to create a drained portion of the vertical part of the pipeline up to and around the aligner; (b) cutting the pipeline at or near the draining of step (a) to create upper and lower open ends of the pipeline; (c) installing a pig into the upper open end; (d) moving the pig through the pipeline to reach a flooding fluid-filled part of the pipeline; (e) adding flooding fluid into the flooding fluid-filled part of the pipeline to reverse the movement of the pig in step (d) and to wholly or substantially refill the drained portion of the pipeline; and (f) installing the In-Line Structure (ILS) to at least the upper open end of the pipeline.

Abstract: A transfer mechanism (28) for transferring a fitting (46) on a flexible tubular conduit (48) about a guiding means (26) of a pipelay tower (20). The transfer mechanism (28) includes a frame (30) adapted to rotate about said guiding means (26); and a clamping mechanism (34) connected to the frame (30) and adapted to connect and secure the fitting (46) to the transfer mechanism (28). Actuation of the transfer mechanism (28) is configured to rotate the frame (30) about the guiding means (26) and cause at least one part of a fitting (46) connected to the transfer mechanism (28) to move along a path outside a surface of the guiding means (26) from a first position upstream of the guiding means (26) to a second position downstream of the guiding means (26).

Abstract: A method for checking a flexible line, the flexible line including at least one layer of armors (24, 25) surrounded by an external sheath (30), the external sheath (30) delimiting an internal space (33) receiving the layer of armors (24, 25) and including at least one medium (M) at the interface between the external sheath (30) and the internal space (33). The method includes sending an ultrasonic signal on a region to be checked of the external sheath (30), and receiving the reflected signal at the interface between the region to be checked of the external sheath (30) and the internal space (33) facing the region to be checked of the external sheath (30); and analyzing the polarity of the reflected signal and determining, according to the analyzed polarity, at least the nature of the medium (M) at the interface.

Abstract: A pipe (14) extending between a surface end (20) and a bottom end (22) thereof, and defining an internal passage (24) ending at the bottom end (22) and at the surface end (20). A dynamic closing member (30) at the bottom end (22), which opens above a threshold pressure applied from the exterior towards the interior of the pipe (14), and closing below the threshold pressure. The threshold pressure is defined as a function of at least one parameter representing the heaving of the pipe under the effect of variation in height of the water in which the pipe extends.
