Definitions

  • the present invention relates to a new pipe system for the collection of petroleum from wells situated in deep waters and to a process for setting up such a pipe system.
  • the present invention relates to a new type of pipe system for transporting petroleum between the well head situated on the sea bed, for example at a depth of 500 meters, and the surface of the sea, where it has to undergo initial treatment and storage so that it may be transported to the refineries.
  • the invention requires, in part and preferably wholly, flexible tubes of known kind.
  • Such flexible tubes are generally constituted by a steel sheath which ensures mechanical strength while allowing deformation, and at least one sealing sheath.
  • the present invention has for its object the novel industrial product consisting of a pipe system for the collection of petroleum issuing from wells in deep water, characterised in that it comprises a lower length of pipe which is situated between the zone of the well head and a level lying below the zone of the surface waves, and which is partly and preferably wholly constituted by a bundle of flexible tubes maintained under tension in positions separated from one another by at least one float situated at the upper part of this length of pipe and preferably by several other floats distributed along the weight of the length of pipe and an upper length of pipe joining up with the upper part of the lower length of pipe, constituted by independent flexible tubes, which bind the upper ends of the flexible tubes constituting the bundles to different points, on the surface of the water, to which the petroleum is to be delivered.
  • the floats used to produce the bundles of flexible tubes should have sufficient buoyancy to ensure tension in the flexible tubes, which are thus kept in a vertical position.
  • flexible systems of another kind e.g., systems for carrying electricity or compressed fluid, for example for controlling mechanisims in the well head or in the well itself.
  • the lower end of the pipe system is provided with a connector, for example of known type, which may be automatically coupled with a corresponding connector fixed to the well head. Different tubes or bundles of flexible tubes are brought into this connector.
  • the flexible pipes or pipe systems may be advantageously fixed to the floats by collars or like attachment means.
  • the flexible pipes or pipe systems are each provided with a coupling connector at the end thereof which is situated at the level of the float above the bundle.
  • the bundle of tubes or the pipe systems is made by placing the pipes or pipe systems on the periphery of the floats, which have a circular or polygonal cross-section, such that the flexible pipes or systems are disposed along the generators of a cylinder.
  • This arrangement has the advantage of allowing relatively simple fixing of the flexible pipes or pipe system to the floats. It also has the advantage of offering reduced resistance to sea currents which may occur at depth.
  • connection of upper and lower pipes and/or pipe systems made equally be carried out across the upper float.
  • the flexible pipes and pipe systems constituting the upper pipe section in such a way that they have of themselves sufficient buoyancy to enable them to come spontaneously to the surface and there to spread out horizontally up to the terminal point.
  • the float for connecting independent flexible pipes on the lower bundle may be situated at a depth of about 20-60 M.
  • connection point has a depth sufflciently great to eliminate the effect of the surface swell but sufficiently small to allow a connection which is easy with the aid of divers.
  • the flexible pipes or pipe systems of the lower bundle may be made by butting together pipes or pipe system e.g. with conventional connectors.
  • the floats which assure the maintenance in a vertical position of the bundle which constitutes the lower length of the pipe system according to the invention are for example distributed every 50 meters of height, without this figure constituting a necessary value.
  • the float may have a buoyancy sufficient to put under tension by upward traction the sections of flexible pipes and pipe systems which they support.
  • the floats should be ballasted so that they can be immersed, and, if required, have adjustable buoyancy.
  • the present invention has equally as an object a process for setting up the pipe system which has just been described.
  • This process being essentially characterized by the fact that with the aid ofa barge, situated over the well, the connector with the well head is immersed after having brought under the control of the connector the ends of the flexible pipes which are to form the bundle, the said flexible pipes being rolled up on reels situated as convenient on the barge and each passing in to a traction and retention device which may be constituted by caterpillar tracks and which allows control of their displacements, that the lower connector is immersed and advanced at the same speed as the flexible pipes; that at the height corresponding to the position of the first float, the flexible pipes are brought under control of the first float which is thereafter immersed; that this operation is repeated with successive floats up to the immersion of a float of the upper part of the bundle which comprises the connectors for the flexible pipes of the upper length that this bundle thus obtained is immersed while proceeding with the automatic coupling of the connector disposed on the lower part of the bunle with the base comprising the well head
  • Fixing of the flexible pipes to the different floats can be effected by any appropriate means, for example with the aid of half-collars which engage on corresponding half-collars integral with the float and placed at its periphery.
  • connection to the base which comprises the wellhead is effected automatically, using for example a known device.
  • FIG. 1 shows a schematic elevation view of the pipe system according to the invention
  • FIG. 2 is a schematic perspective view showing how different flexible pipes are connected to a float to form the bundle
  • FIGS. 3 and 4 are elevation and plan views ofa barge which sets up the bundle of flexible pipes according to the invention.
  • FIG. 1 The structure of the pipe system according to the invention has been shown very schematically in FIG. 1.
  • seabed I can be seen, together with base 2 comprising the wellhead.
  • the lower part of the bundle is furnished with a counter-base 3 for automatic coupling to the base 2.
  • the lower length of piping of the pipe system according to the embodiment shown is constituted by a bundle of flexible pipes which extends between the base 2 and the upper float 4.
  • the float 4 can for example be immersed at a depth of some tens of meters.
  • a float can, for example, be placed at every meters.
  • FIG. 2 An embodiment of the floats and the fixing of the flexible pipes to the floats is shown schematically in FIG. 2.
  • the float 6 has the form of a cylindrical volume with a vertical axis and furnished with a plate 14 at its upper part.
  • the periphery of the plate 14 is furnished with semicircular recesses 15 to receive the flexible pipes.
  • the flexible pipes such as 10,11 and 12 are held in the recesses of the plate 14 by half-collars 16 fixed to the plate by bolts 17.
  • the flexible pipes are brought into the upper part of the float, but of course this disposition is in no way obligatory and the flexible pipes could be fixed likewise to the middle or to the lower part of the float. In other respects, the flexible pipes could be fixed to the floats by any appropriate means.
  • FIGS. 3 and 4 it is schematically shown how it is possible to fix the bundle with the aid of a barge 18 of which one end has been shown in longitudinal section in FIG. 3 and in partial plan view in FIG. 4.
  • the barge 18 comprises. at its end or at its middle a cut-out part or well 19, to enable the flexible pipes to be immersed.
  • the different tubes or flexible pipings which are to constitute the bundle are wound on reels 20,21,22, 23 and 24, as can be seen in. FIGS. 3 and 4.
  • the other side of the barge not shown in FIG. 4 of course likewise comprises analogous reels.
  • FIGS. 3 and 4 the flexible pipes 7,8,9 and which unwind from the reels and which each pass over a drive device with caterpillar tracks 25 enabling their progress to be controlled.
  • the float 6 and also the half-collars 16 which enable the flexible pipes to be fixed on the float have been shown schematically in FIGS. 3 and 4.
  • the float 6 is supported by a crane 27 which enables the different floats to be displaced and introduced into the well when they are to be secured to the flexible pipes.
  • the lower connection 3 is first placed in the well 19, supporting it by means of the crane 27.
  • connection 3 To the connection 3 are secured the ends of the different flexible pipes 7,8,9,l0, 11, etc., then the connection is progressively immersed while the caterpillar tracks 25 ensure the controlled displacement of the flexible pipes.
  • connection of the independent upper flexible pipes is effected by conventional means with the aid of undersea divers.
  • the pipe system according to the invention has the advantage of particularly simple placement which can be effected from a conventional barge.
  • the vertical bundle is constituted by flexible pipings enables transverse currents to be withstood more easily, even if these currents are oriented in different directions at different depths.
  • the lower part of the pipe system can be constructed in part from at least one rigid tube and in part from a bundle of tubes or flexible pipings such as has been described.
