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 tube heat exchanger extending in a vertical direction, comprising: a first chamber including a lower portion provided with at least one intake inlet for a diphasic fluid including a liquid and a first vapor containing a mist; an upper portion; and a first recovery member passed through by the first vapor and recovering the mist in liquid form, the first vapor next arriving in the upper portion, a central chamber forming liquid films running over the tubes and vaporizing at least partially to produce a second vapor, the tubes being traveled inwardly by a fluid hotter than the diphasic fluid, and a second chamber receiving the first vapor and the second vapor to form a third vapor, and including an outlet for the non-vaporized liquid and an outlet for the third vapor, the first chamber and the second chamber together forming a volume surrounding the central chamber around the vertical direction.

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.

Abstract: A method for determining the bend of a tubular structure, including determining the inclination of first and second rigid objects fixed in distinct locations along the tubular structure. The method includes supplying accelerometers (A1, . . . AN) rigidly linked by the object to measure an acceleration in at least one direction of measurement (vj), the respective directions of measurement of at least two of said accelerometers being non-collinear. The measurement, by the accelerometers, of the components of the Earth's gravitational field along said directions of measurement, the measurement providing, for each of said directions, a measurement value, denoted mj for a measurement direction of index i. The method includes solving a defined matrix equation to determine the inclination Φ of the object relative to the reference frame of reference.
