Abstract:
Methods of rotary friction welding a (e.g., concentrically) threaded connector to a subsea-type riser or flowline pipe segment and/or of rotary friction welding cladded pipe segments. Subsea-type riser or flowline pipe segment with a (e.g., concentrically) threaded connector fused to the pipe segment at an autogeneous friction welded seam, and/or subsea- type riser or flowline cladded pipe segments fused together at a friction welded seam.
Abstract:
Pour intervenir sur une canalisation sous-marine, un appareillage comprenant un système d'émission d'ultrasons et au moins un transducteur de réception d'ultrasons (20) est descendu dans le milieu marin. Dans une phase d'inspection, une source ultrasonore d'inspection (14, 14a) du système d'émission d'ultrasons et le transducteur de réception sont disposés de part et d'autre de la canalisation, la source d'inspection est activée, et un signal ultrasonore capté par le transducteur de réception est enregistré. Une condition de localisation d'une obstruction est détectée à l'emplacement où sont disposés la source d'inspection et le transducteur de réception en réponse à l'observation d'une anomalie dans le signal ultrasonore capté par le transducteur de réception à cet emplacement. Dans une phase de destruction, une source de puissance (14, 14b) du système d'émission d'ultrasons est alors couplée à la canalisation à cet emplacement, et la source de puissance est activée pour détruire l'obstruction.
Abstract:
An apparatus for installation and protection of subsea cables comprises at least a first tubular member (1) and at least a second tubular member (2). Both these are arranged to be installed subsea with a subsea foundation (3). This allows passage of cable (29) through it. The first tubular member (1) is arranged telescopically within the second tubular member (2) so as to extract outwardly towards seabed (5) from an end portion (7), with respect to the second tubular member (2), only up to a prefixed length. This ensures that a continuous conduit for the cable is obtained through the scour protection of the foundation (3). The present invention also includes a methodology for installation of the apparatus and a method for installing a cable through the scour protection of the foundation, by using the apparatus.
Abstract:
A stab connector for providing a fluid flow path between a first fluid reservoir and a second fluid reservoir, comprising a stab body coupleable to a receptacle in fluid communication with the second fluid reservoir and moveable inside the receptacle between a sealing position, in which fluid flow in the fluid flow path between the first fluid reservoir and the second fluid reservoir is prevented, and a flow position, in which the fluid flow in the fluid flow path between the first fluid reservoir and the second fluid reservoir is permitted.
Abstract:
A technique for repairing or modifying a pipeline (1) is described where a plug of gel (12, 13) is formed inside the pipeline (1), by injection of gel through the pipeline wall, to restrict the fluid contained in the pipeline (1) from accessing at least one repair or modification location (16) along a length of the pipeline (1). At least one repair or modification operation may be performed on the pipeline (1) at the repair or modification location (16) to repair or modify the pipeline (1).
Abstract:
To clean the inside of a pipe length 6 a swabbing machine 2 is provided at a first end of the pipe length 6, the swabbing machine 2 comprises a pneumatic motor 3 and is propelled along the inside of the pipe length 6 in a first direction away from the first end of the pipe length 6 by the pneumatic motor 3. A swabbing machine and a swabbing machine system are also disclosed.

Abstract:
Interlocking bend limiter sections are substantially mirror images of each other and are joined to form an interlocking bend limiter segment without use of fasteners by engaging each other's interlocking ends. An interlocking bend limiter comprises a plurality of interlocking bend limiter segment secured at an end by an end piece. In alternative, related embodiments a repair system comprises one or more machinable length sections which function as chain clamps to repair a subsea pipeline while the subsea pipeline is still in service and which can comprise interlocking sections similar to bend limiter sections or which are locked in more traditional manners such as by using bolts or other fasteners.
Abstract:
A clamping device for clamping together two subsea tubular members, the device comprising: a force applying member which is operable to apply a force in a first direction to bring the two subsea tubular members into contact with each other and subsequently generate a compressive clamping force, the applied force defining a load path; and a reaction member which is couplable to at least one of the tubular members such that the reaction member is located in the load path to provide a reaction force in a second opposite direction.
Abstract:
The present invention is for coating a surface area of a gap in the coating of a pipeline, said surface area having a length along the central longitudinal axis of the pipeline and a width of at least part of the circumference of the pipeline. The device according to the invention comprises: • a frame (3); • a spray nozzle support element (33) supporting a number of spray nozzles (35); • a linear motion mechanism (39) configured for translating the spray nozzle support element relative to the frame and parallel to a longitudinal axis of the frame (9); and • support members (15,16,17,19) configured for arranging the frame stationary relative to the pipeline (13) with said longitudinal axis of said frame coinciding with the central longitudinal axis (9) of the pipeline;
