Definitions

  • Pipeline pigs are used for variety of purposes in the construction, operation and maintenance of pipelines for the transport of e.g. hydrocarbons.
  • One very important function is testing submerged or buried pipelines for leaks, corrosion, erosion or other damage since pipelines of this type are not readily accessible from the outside.
  • the pigs may carry advanced equipment for performing and registering various measurements and a power source, normally in the form an electric battery.
  • Most conventional pigs of this type comprise an elongate body and one or more disks or cups at each end, the peripheral parts of the disk or cups being made of flexible material and fitting snuggly within the pipeline so that the pig will be carried along with the fluid flow in the pipeline.
  • the pig cannot be controlled after it has been launched from one end of the pipeline, and at the other end a rather elaborate pig trap and sluice must be arranged for recovering the pig, preferably without damage to its advanced equipment.
  • Some submerged pipelines extend for hundreds of kilometers between pumping stations and it is clearly inefficient to send a pig all that distance if, for instance, only the section of the pipeline closest to one or both of the end points needs checking.
  • some underwater pipeline systems reco ⁇ very of the pig is not possible in a conventional manner. In such systems, therefore, double parallel pipelines have been contemplated for returning the pig.
  • a rather specialized type of pig, particularly intended for cleaning purposes, is known from US-PS No. 2 596 571.
  • This pig comprises a main body fitting with a small clearance inside the pipeline so as to be carried along with the fluid flow.
  • the casing has a number of axial passages which will permit some fluid flow through the pig, this flow being directed to impinge on the vanes of a turbine supported -for free rotation in the main body.
  • the turbine is provided with an excentric weight so that when the turbine rotates, the excentric weight causes an unbalanced rotating force which will set the entire pig vibrating in order to improve its cleaning capabilities and reduce the risk of it getting jammed by sediments in the pipeline.
  • a pipeline pig comprising a body provided with means for positioning same in a pipeline and propulsion means utilizing a pressure differential across the pig to propel the pig along the pipeline, said body having at least one generally axial passage to permit at least some flow therethrough of the fluid transported in the pipeline, said body further comprising rotat- ably supported means drivable by said flow for con ⁇ verting hydrostatic energy in said fluid into mechanical energy, the invention being characterized in that said rotatably supported means is coupled to at least one driving means being engagable with the inside of the pipeline for driving the pig along the pipeline.
  • the pig according to the invention will be able to move both against and with the fluid flow in the pipeline and stop wherever wanted.
  • the energy conver ⁇ ting means may also be used to supply energy to instrumentation carried by the pig. Since all energy required may be taken out of the pipeline flow, there is no limit to the distance the pig may travel.
  • the pipeline is designated 1.
  • the pig com ⁇ prises a body 2 consisting generally of a piece of pipe having an external diameter somewhat smaller than the internal diameter of the pipeline 1.
  • the body 2 is provided with wheels 3 supported for rota ⁇ tion and limited radial movement in wheel wells 4 and biased towards the inside of the pipeline 1 by means of a spring 5.
  • the wheels 3 will keep the body 2 of the pig centered in the pipeline.
  • radial webs 6 support a
  • housing 7 shaped generally like a drop in order to represent the least possible flow resistance.
  • the nose of the housing is a turbine 8 with vanes 9.
  • the turbine is mounted on the input shaft 10 of a hydrau ⁇ lic pump 11.
  • brackets 12 are arranged forming supports for pivot- able arms 13.
  • Each arm 13 carries an hydraulic motor 14 (shown in broken lines), on the output shaft 15 of which a drive wheel 16 is mounted.
  • the drive wheels it 16 are forced against the pipeline wall by means of a hydraulic cylinder 17 with piston rods 18.
  • the cylinder 17 is hydraulically connected to the pump 11 by means of lines 19.
  • the motors 14 are also connected (not shown) .to these lines, e.g. through
  • the pipeline fluid will be flowing through the body 2 of the pig, e.g. from the left to the right in the drawing. This flow will be
  • Hydraulic fluid from the pump will also flow to the motors 14 for rotating the wheels 16.
  • the direction of rotation of the wheels 16 may be such that the pig will move from " the right to the left in the drawing, i.e. against the direction of
  • the hydraulic motors 14 being reversible, the direction of rotation of the wheels may be changed by simply switching the flow direc ⁇ tion through the motors, thus making the pig move in the opposite direction, i.e. the same as the pipeline flow.
  • the pump 11 and the hydraulic motors 14 may be replaced by electrical equivalents, i.e. an electric generator and electric motors.
  • hydraulic and electric systems may be combined, particularly where electric power is needed for instrumentation (not shown) to be carried by the pig.
  • the driving system may be purely mechani ⁇ cal, the rotation of the shaft 10 being transmitted to the wheels 16 through suitable shafts and gearing. Varying the speed and driving force of the pig may be accomplished in various ways, depending on the drive system. If mechanical, the gear ratio may simply be changed. If hydraulic, the pump may be of the variable capacity type being able to deliver higher pressure at lower flow rates. Also, the pitch angle of the turbine vanes 9 may be changed.
  • - Means will normally be included in ' the pig for controlling its movements and instrumentation.
  • Such control means may in turn be controlled by acoustical signals, as is well known in the art, or by means of a programmable micro computer, which is also well known in the art.
  • the pig may also include equipment for automatically reversing the direction of travel when the pig arrives at the end of the pipeline or encounters an obstacle which cannot be passed.
  • the body of the pig need not be constituted by an elongate cylinder with a diameter close to that of the pipeline, but may take various other " forms adapted to the purpose of the pig, e.g. so as to make it able to mergeate bends in the pipeline.
  • the drive wheels may be replaced by caterpillars, and the rotating motors may be replaced by linear motors moving the pig in a stepwise fashion.
  • the pig may comprise more than one turbine, e.g. one for propel ⁇ ling the pig and another for producing power for the instrumentation and control circuitry.
  • two or more turbines may be used for each of these functions.
  • the invention may be employed with either gaseous or liquid fluids in the pipeline. If the pipeline and fluid are clean, the fluid may even be used as the working medium in a fluidbased energy transmission system.

Abstract

Un furet gratteur pour pipelines comprend un corps (2) pourvu d'éléments (3) pour positionner le furet dans un pipeline (1). Le corps (2) permet l'écoulement du fluide transporté dans le pipeline à travers le furet sans créer une chute sensible de pression. Le furet est pourvu d'une turbine (8) actionnée par l'écoulement du fluide, la turbine à son tour actionne des roues (16) pressées contre le paroi de la canalisation. La transmission de puissance peut être exécutée par une pompe (11) actionnée par la turbine (8), la sortie de la pompe actionnant à son tour des moteurs hydrauliques (14) connectés aux roues (16). Un cylindre hydraulique (17) connecté à la pompe (11) peut être utilisé pour presser les roues (16) contre la canalisation. Le système de commande est de préférence réversible, de sorte que le furet puisse se déplacer avec et contre le courant de fluide dans la canalisation. Le furet peut porter des instruments de côntrole de l'état de la canalisation, et la puissance nécessaire à ces instruments peut être fournie par un générateur actionné par la turbine (8). Aussi bien les instruments que le mécanisme d'inversion peuvent être commandés par des signaux acoustiques ou par un ordinateur électronique incorporé au furet.
