Definitions

  • a device for oiT-centering an above-water articulated drilling structure in relation to a base on the seabed [30] Foreign Apphcauon Pmmty Data consisting of a roller-table on the base, surmounted by M81. 5, 1971 France a vertical pivobshaft a circular roller.path also on the base and concentric with the pivot, an off-centering U-S- carriage that can revolve round the pivot upported the roller table and rolle zpath and a guide- Fleld of Search .6, 52, ramp along the lower end of the main articula- 175/7, 8, 9, 61/46, 46-5, 81 tion of the structure can slide, and means for rotating the carriage and sliding the articulated structure along [5 6] References Cited the guide-ramp.
  • the present invention offers a way of overcoming such problems, by providing an off-centering device which allows the articulated structure to revolve or move transversely in relation to the base.
  • this device allows multiple wells to be drilled in a circle by the central part of the structure. When drilling is over, the structure can be moved back to the center of the site, allowing direct access to wells already drilled and installed, for servicing or inspection.
  • the off-centering device as in the invention linking a base on the seabed to the articulation of an abovewater articulated structure, consists of a roller-table on the base, surmounted by a vertical pivot-shaft, a circular roller-path, also on the base and concentric with the pivot, an off-centering carriage that can revolve round the pivot, supported by the roller-path and roller-table, with a guide-ramp on top, along which the lower end of the main articulation of the structure can slide, and means of rotating the carriage and sliding the articulated structure along the guide-ramp on top of it.
  • the carriage has an opening through which the components of a drilling or servicing wellhead can pass.
  • the means of rotating the carriage consist of a rack alongside the rollerpath, a device on the off-centering carriage with wheels or rollers, which run on the roller-path, and a displacement system incorporated in the carriage and resting on the rack.
  • the system consists of one or more double-action end jacks on the carriage, operating blocks which fit into the slots in the rack, acting as stops.
  • the system consists of one or more double-action end jacks on the carriage, operating self-blocking ratchets which engage in the rack.
  • Another type of system that may be used consists of a hydraulic motor on the off-centering carriage, driving a pinion which engages with the rack.
  • the system for sliding the articulated structure along the guide-ramp consists of a rack alongside the ramp, a device on the lower end of the main articulation of the structure, with wheels or rollers which run on the ramp, and a displacement system on the lower end of the articulation, resting on the rack.
  • This displacement system is preferably similar to those for rotating the off-centering carriage, as described above, although other equivalent systems also come within the framework of the invention.
  • the pivot-shaft on the roller-table contains effluent pipes, consisting of one passage for the supply of production-well effluents andanother for their removal.
  • FIG. 1 is a diagrammatic side view of the articulated structure, off-centering device and base.
  • FIG. 2 is a schematic section view of the installation FIG. 1, taken along the line II-lI of FIG. 1, looking downward.
  • FIG. 3 is a schematic section view of the offcentering device fitted to the base, taken along the line III--III of FIG. 1 looking downward.
  • the base (I), resting on the seabed (26), is of standard type, constructed to suit the individual features of the site. It is designed to take a number of drilling or servicing wellheads, which are passed through and, once installed, are protected by the base.
  • the pivot has two separate central passages, for the effluent produced by the well and sent to the treatment installation, and for removal of the treated effluent.
  • One of these passages is linked with the pipes (5) connected to the underwater manifolds (6), and the other to the pipe (7) by which production is removed after treatment.
  • the pivot also acts as a link for the remote controls (8) for the under-water installations.
  • An off-centering carriage (9) rests on the base (1). It can revolve on the roller-path (2) and roller-table (3), by means of a system with coupled, superimposed wheels (10), to prevent loss of balance during movement.
  • the carriage is moved by means of double-action end jacks (11), hydraulically controlled from the surface, and operating blocks which fit into the slots in the rack alongside the roller-path.
  • the top of the off-centering carriage slopes slightly, and has a guide-ramp (12), with a rack.
  • the lower end (13) of the main articulation (14) of the structure fits on to this guide-ramp, and is made to slide along it by jacks (15), which also operate blocks fitting into the slots in the rack along the ramp, causing the whole articulated structure to move transversely.
  • the articulated structure (16) contains a number of passages (17) in a circle round its axis, with exactly the same diameter as the circle of wells on the base (1).
  • passages can be used to insert tubes (18), when instruments need to be installed. This is not possible until the final phase of drilling has been reached and the articulated structure has returned to its original position and is no longer off-center, so that each passage (17) corresponds to a well installed on the base.
  • the structure also contains one passage (19) with a larger diameter than the others, which in the off-center or drilling position, is in alignment with the pivot-shaft (4).
  • Two coupled pipes (20) can be inserted in this passage and connected to the corresponding passages in the pivot, to convey the effluent from production wells to the treatment plant at the upper end of the structure, and remove the treated effluent.
  • the remote-control lines (8) for the wellhead installations and jacks also pass through it.
  • the articulated structure also contains a central passage (21), running through the whole installation, including the articulation (14). This passage is large enough to accomodate drilling wellheads, so that they can be installed in the base.
  • Two equipment passages (22) are also provided for installation operations on well during the drilling of subsequent wells, or to allow a diving bell to pass.
  • the part (24) of the articulated structure above the surface (25) has all the drilling equipment on separate levels, away from the well-access passages (17). Production installations are isolated from drilling installations, to ensure complete safety.
  • the installation according to the invention is installed and operated briefly as follows.
  • the articulated structure (16) is towed out to the site, positioned, and attached in the standard way to the off-centering carriage (9), previously installed on the base (1). The structure is then in the centre of the installation.
  • Jacks (l) controlled from the surface, slide the structure transversely along the guide-ramp (12) on the off-centering carriage, to an end position, corresponding to the radius of the circle of wells to be drilled. Other jacks (11) then take over, moving the carriage round the pivot-shaft (4), to position the articulated structure over the spot chosen for drilling.
  • the vertical stress at the level of the articulation can be adjusted by de-ballasting the articulated structure. This is done only while the structure is being moved. Once positioned, it is again stabilized.
  • the articulated structure used for drilling can also be replaced, once drilling is completed, by an articulated structure designed solely for hydrocarbon production and treatment, and repairs to defective wells.
  • the pivot-shaft (4) in the off-centering device allows the articulated structure to be changed with complete safety, and its design ensures total protection of wellheads during the operation.
  • a device for mounting a structure which projects above the water in an eccentric position with respect to an underwater base comprising a carriage
  • a device as claimed in claim 1 in which said structure contains a central vertical passage and a plurality of additional passages arranged in a circle centered on said central passage.
  • a device as claimed in claim 4 in which said structure supporting means is a ramp positioned to permit movement of said structure between a position in which said central vertical passage is in alignment with the vertical shaft on said base and a position in which one of said additional passages is so aligned.
  • a device as claimed in claim 1 in which said carriage-supporting means comprises a circular roller-path on said base and a plurality of rollers mounted to roll on said path between said base and carriage.
  • a device as claimed in claim 6 in which said means for rotating said carriage on said base comprises a rack parallel to said roller path and power means carried by said structure for actuating drive means engaging said rack.
  • a device as claimed in claim 1 in which the means for moving said structure on said carriage comprises a rack and power means which actuates drive means cooperating with said rack.
