Abstract: A method of applying protective sheeting of polymer material to a pipeline, such as on a J-lay rig, includes the steps of driving a carriage along an annular path about the pipeline; extruding and simultaneously winding the protective sheeting about the pipeline via an end extrusion die fitted to the carriage; compressing the protective sheeting on the pipeline, directly downstream from the end extrusion die, so the protective sheeting adheres to the pipeline; and controlling the drive, extrusion, and compression steps so that the time lapse between expulsion of a cross section of protective sheeting from the end extrusion die and compression of the same cross section of protective sheeting is less than one second.

Abstract: A lower stack assembly of a blowout preventer for a hydrocarbon extraction well includes a safety function that can be hydraulically activated to rapidly cut off a pipeline section. The assembly includes a first valve and a first fluidic connection connecting the first valve and the least one safety function, so that the first valve selectively cuts off a flow of fluid directed towards the safety function. The assembly further includes a port operatively connected to the first valve, cooperating with a remotely operated vehicle to transmit a pilot signal to the first valve, an accumulator housing pressurized fluid, and a second fluidic connection. By cooperating with the first valve, the accumulator supplies pressurized fluid to the safety function to activate it. The second fluidic connection connects the accumulator and the first valve, so that the second fluidic connection remains operative during the entire working life of the assembly.

Abstract: A method for burying a pipeline in a bed of a body of water which includes: making a trench with a bottom surface in a bed of a body of water via a bed working vehicle advanced in an advancing direction; advancing a floating unit in the body of water; releasing a pipeline in the body of water via a tensioner and along a lay device tilted in an adjustable manner and constrained to the floating unit; guiding the pipeline to the bottom surface of the trench via a guide vehicle advanced on the bed of the body of water; and controlling the tensioner, the floating unit, the lay device, the bed working vehicle, and the guide vehicle to minimize stress along the pipeline.

Abstract: A lifting apparatus comprises: a base part, a lifting rope, a sheave assembly, a first rotatably mounted sheave, around which the rope passes and from which the rope extends downwardly to a load, a second rotatably mounted sheave and a drive for moving the sheave assembly. The sheave assembly is mounted for pivotal movement relative to the base part about an axis of pivoting spaced from the axis of rotation of the first sheave and coincident with the axis of rotation of the second sheave. During movement of the load relative to the base part, the first sheave is moved by the drive to compensate for that relative movement, the movement of the first sheave being such that the vertical component of the movement of the first sheave relative to the load is less than the vertical component of the movement of the base part relative to the load.

Abstract: A system for connecting two conduits in a body of water, exhibits a first tubular structure, which is coupled to a conduit that extends along a first longitudinal axis; a second tubular structure, which is coupled to another conduit that extends along a second longitudinal axis and comprises a tubular member, and a sleeve, which is telescopically coupled to the tubular member, and faces the first tubular structure; and an actuating assembly, which comprises a bidirectional translating device configured to selectively displace the sleeve forward and backward to selectively couple and uncouple an end portion of the sleeve and the first tubular structure.

Abstract: A method of joining a tubular member and a pipeline configured to convey corrosive products comprises preparing a tubular member with an inner seat; inserting the end of a pipeline inside the inner seat; inserting a sleeve of corrosion-resistant material inside the end of the pipeline; inserting an expandable mandrel inside the sleeve; and expanding the expandable mandrel to join the end of the pipeline and the tubular member, and seal the sleeve and the pipeline to protect parts of the pipeline, sensitive to corrosive products, via the sleeve.

Abstract: An internal line-up clamp (20), for aligning two pipes to be welded together, includes a hi-lo measurement system, for example includes a laser source (24) and camera system (22), mounted on the internal line-up clamp (20) and arranged to make a hi-lo measurement (d), indicative of the degree of alignment of the pipes (10a, 10b). The measurement may be made when two pipes are clamped together by means the internal line-up clamp (20). The pipes may then be welded together, whilst the pipes remain clamped together in the same position, and whilst the hi-lo measurement system remains inside the pipes.

Abstract: A damping device (1) for pipelines (2) includes a compression ring (3) with three ring segments (4) that can be positioned around a pipe (2). Each ring segment (4) forms a damper seat (8) that receives at least one damping element (9) made of elastomeric material intended to be radially compressed against an outer surface of the pipe (2). The damper seat (8) is in shape connection with the damping element (9) so as to prevent the damping element (9) from being released from the damper seat (8) in an axial direction and in a radial direction.

Abstract: A joining device of a continuous conduit is for changes in slope of seabeds. The continuous conduit defines a longitudinal direction substantially coinciding with the longitudinal direction of structural development of the continuous conduit. The continuous conduit has a longitudinal structural continuity and a fluidic continuity. The joining device includes a joint that includes at least one first joining branch, at least one second joining branch and at least one third joining branch. The first joining branch extends along the longitudinal direction and provides longitudinal structural and fluidic continuity of the continuous conduit and connects with a piece of the continuous conduit. The second joining branch provides longitudinal structural continuity of the continuous conduit. The third joining branch provides fluidic continuity of the continuous conduit. The second joining branch is exclusively suitable for providing the longitudinal structural continuity of the continuous conduit, and is unsuitable for providing the fluidic continuity.
