Abstract:
Embodiments of a jumper tube connection assembly generally include a retention clip having beveled and locking surfaces, a retention clip frame, and a biasing means, wherein the clip is restrained partially within the frame and is pivotable in response to a jumper connector contacting the beveled surface during shunt tube engagement therewith, and wherein the biasing means positions the locking surface to prevent jumper connector reverse movement. Other embodiments generally include a retention clip having a locking component, a retention clip support, and a biasing means, wherein the clip is restrained partially within the support and is pivotable in response to force biasing the locking component away from a shunt tube during jumper connector engagement therewith, wherein upon force cessation the biasing means positions the locking component in engagement with a jumper connector orifice, thereby preventing disengagement thereof from the shunt tube. Methods of utilizing the embodiments are also provided.

The device further includes a welding module (14) that is rotatably coupled to the crawler module (12) and has a welding head (35) mounted thereon, wherein the welding module (14) automatically rotates in an opposite direction and at a same rotational speed relative to a direction and rotational speed of the crawler module (12) to maintain an angular position of the welding head (35).
Abstract:
A subsea connection system (10) for connecting to a hub (14) has a body (12) with an interior passageway suitable for allowing fluids to flow therethrough, a collet having a plurality of collet segments (30) that are movable between a locked position and an unlocked position, an outer sleeve (18) overlying the collet, and a translator (24, 26, 20 and 54) cooperative at the outer sleeve so as to move the outer sleeve between a first position and a second position. The plurality of collet segments (30) are in the unlocked position when the outer sleeve is in the first position. The plurality of collet segments are in the locked position when the outer sleeve is in the second position. The locked position is adapted to secure the body in connection with the hub.
Abstract:
A method of laying lined pipeline which actively and successfully removes air pockets which might be trapped in the annulus between the liner and the host pipe by progressively flooding the lined pipeline. Furthermore, the liner is brought into closer contact and engagement with the host pipe. The removal of air in the annulus enables the pipeline test pressure to stabilise more quickly and avoids the risk of potential collapse during operational service life in the event the pipeline pressures fluctuate or a vacuum is created during an emergency shutdown.
Abstract:
A joining device (9) for joining two facing and aligned pipeline sections presents two coupling members (37, 38) selectively couplable to respective pipeline sections (4, 5) at two respective facing flanges (27, 28) located at the ends of respective pipeline sections (4, 5); a pulling mechanism (39) suitable to move the coupling members (37, 38) towards each other in abutment against the flanges (27, 28) and to temporarily tighten the flanges (27, 28) by moving the coupling members (37, 38) towards each other; and a tightening mechanism (40) suitable to definitively tighten the coupling members (37, 39) while the pulling mechanism (39) keeps the flanges (27, 28) tight.
Abstract:
A gripping device(5), such as a split clamp, sealing device and/or structural support, is configured to grip, engage or fix onto a pipe, pipeline, conduit or other elongate member (45). The gripping device (5) includes one or more gripping mechanisms (25a, 25a', 25b, 25b') configured to grip, engage or fix, such as mechanically grip, engage or fix, onto the pipe, pipeline, conduit or other elongate member and first and second parts (10a, 10b), wherein the first and second parts (10a, 0b) are disposed relative to each other or secured or securable together so as to circumferentially surround the pipe, pipeline, conduit or other elongate member (45). A corresponding gripping mechanism and methods of operating, assembling the gripping device, sealing and repairing a pipe, pipeline, conduit or elongate member are also provided herein. In other examples, the gripping device may be a flange, T-piece or 1 valve, the flange, T-piece or valve being configured to retain, grip, engage or secure a portion of a pipe, pipeline, conduit or other elongate member.
Abstract:
A system for supporting an end section (1) of a flexible conduit when the conduit is lowered into the sea and installed at the seabed, the system (10) comprising: -a termination head (20), which is to be permanently fixed to the end section of the conduit; and -a lifting yoke (40), which has an upper end (41) and a lower end (42), an attachment (43) configured for engagement with a lifting wire being provided on the lifting yoke at the upper end thereof. The lifting yoke is configured to be detachably connected to the termination head through a joint (44) formed between the lower end of the lifting yoke and a rear structural part (24) of the termination head, the termination head being pivotable in relation to the lifting yoke, about a horizontal pivot axis (45) formed by said joint, from a vertical position to a horizontal position.
Abstract:
A method of handling a discrete elongate subsea element (32) of determinate length, such as a spool of rigid pipe. The method comprises shortening a tensile chord system (44) acting on longitudinally-spaced locations (52) on the element to apply longitudinally-compressive forces to the element. The compressive forces bend the element along its length against elastic recovery force to shorten the span of the element. One end of the element is anchored at a first anchorage (34) before or after the element is bent. The other end of the element is anchored at a second anchorage (34), after the element is bent and while the element remains bent. The method is apt to be used during installation of the element, where the anchorages are both underwater, and during transportation of the element, where the anchorages are hang-off platforms of a surface vessel.
