Definitions

  • the present invention regards an apparatus and a method for penetrating the pipewall and setting up a connection point in a pipe containing fluid under pressure.
  • the invention is relevant for pipes situated on land, in water or buried, containing fluid of any type under pressure, but is in particular relevant for pipelines containing hydrocarbons under pressure, in particular pipelines laid out under water, whereto a connection point is to be set up without prior shut down of the pipe line.
  • Such setting up of a connection point in a pipeline under pressure, and the connection point itself is termed a "hot tap" in the petroleum industry.
  • the invention regards a method for diverless, remote setting up of a connection point in a pipeline under water containing fluid under pressure, hence a remote hot tap.
  • the embodiments based on gluing are insufficient with respect to withstanding high pressure.
  • the embodiments with pretensioning of a whole saddle formed plate placed towards the pipeline surface further require a large pretensioning pressure and a very fine, even surface on all sealing surfaces, in order to function satisfactorily.
  • the embodiments at present used by the petroleum industry on pipelines deployed in water, require welding and/or use of divers. Welding subsea, hyperbaric welding, requires setting up of a dry chamber and comprehensive use of divers and support functions, and diving is at present in the Norwegian sector limited to depths less than 180 meters.
  • an apparatus for penetrating the pipewall and setting up a connection point in a pipeline containing fluid under pressure, which apparatus comprises a mounting device for stable and correctly aligned mounting on the pipeline, a transition section from the mounting device to a pretensioning device, a seal for sealing against the pipeline surface, a volume for holding the pipeline pressure, a valve and a borer, and optionally additional mechanical connections, valves or devices, and the apparatus is distinguished in that the volume is formed by an inner pipe that fits into and is longitudinally movable in the transition section, where the inner pipe in one end towards the pipeline is equipped with seal and further away from the pipeline is equipped with one or more first reaction points for affixing the pretensioning device, the valve, and further in the other end with a first mechanical coupling for connecting the borer, where the inner pipe via the one or more first reaction points and the pretensioning device is connected to one or more second reaction points on the transition section.

Abstract

La présente invention concerne un appareil qui permet de pénétrer la paroi d'une conduite et de créer un point de connexion dans une canalisation (1) contenant du fluide sous pression, cette invention se caractérisant en ce que l'appareil comprend un dispositif d'installation (2) qui permet l'installation stable et correctement alignée sur la canalisation, une partie intermédiaire (3) qui va du dispositif d'installation jusqu'à un dispositif de précontrainte (4), un joint (5) qui se place de manière étanche contre la surface de la canalisation, un volume (6) prévu pour supporter la pression de la canalisation, une vanne (7) et un dispositif de perçage (8) et facultativement d'autres connexions mécaniques, vannes ou dispositifs supplémentaires. L'appareil se distingue en ce que le volume (6) est formé par un tube interne (9) qui se loge dans la partie intermédiaire (3) et qui peut se déplacer longitudinalement dans cette dernière, ladite partie interne étant équipée d'un joint (5) à une extrémité orientée vers la canalisation et comportant, loin de ladite canalisation, un ou plusieurs premiers points de réaction (19) servant à fixer le dispositif de précontrainte (4), la vanne (7), et comprenant dans l'autre extrémité, un premier couplage mécanique (11) servant à connecter le dispositif de perçage (8), ledit tube interne (9) étant relié, par l'intermédiaire du ou des premiers points de réaction (19) et du dispositif de précontrainte (4), à un ou plusieurs deuxièmes points de réaction (12) situés sur la partie intermédiaire. Cette invention concerne également des procédés destinés à être utilisés avec l'appareil ainsi que l'utilisation dudit appareil.
