Definitions

  • the present invention relates to the handling of underwater pipelines and more particularly relates to a method and assembly for handling, repairing and/or reinforcing subsea pipelines, generally pipelines for oil, gas and other fluids. While specific reference will be made in this specification to the application of the inventive assembly in the oil field, and offshore applications, this technique and apparatus may be well applied to other fields where a pipeline should be reinforced and/or repaired, or pipe lengths have to be joined, in underwater or in any other environment where a section of the pipeline should be isolated from the environment.
  • a sleeve For repairing the section a sleeve is lowered under the water and placed concentrically around the pipeline section, with the sleeve being preferably formed by a pair of halves that are connected and placed around the section.
  • the sleeve is installed onto the pipeline and firmly retained therein by means of clamps fixed around the sleeve, screws or any other means. Since the sleeve has an inner diameter that is larger than the outer diameter of the pipeline section an annular chamber is defined between the sleeve and the pipeline, which chamber is filled with a resin to reinforce the pipeline. There is a drawback however in connection to the curing of the resin into the chamber. Such curing takes some hours and requires a completely dry environment, which conditions are difficult to meet in an under water scenario.
  • a repairing assembly for repairing a section of a subsea pipeline, the assembly comprising: a sealing cylindrical sleeve with an inner diameter larger than an outer diameter of the pipeline section, whereby when the sleeve is concentrically installed onto an outer surface of the pipeline section, the sleeve forms a watertight annular chamber around the pipeline section; at least two ports passing through a wall of the sleeve for injecting and flowing a drying fluid into the chamber, and for injecting a resin through one of the ports into the dry chamber for filling the chamber, and means for closing the ports after filling the chamber with the resin.
  • FIG. 1 shows a longitudinal cross-sectional view of a work vessel and a pipeline section lying on a sea bed
  • FIG. 2 shows an elevation cross-sectional view of a pipeline section with a sleeve of the invention installed therein
  • FIG. 3 shows a cross sectional view taken along line III-III of Figure 2
  • FIG. 4 shows a longitudinal cross sectional view of a pipeline section with a repairing assembly of the invention installed therein
  • FIG. 5 shows a cross sectional view of a port of the assembly according to the invention.
  • FIG. 1 a pipeline 1 that is lying or otherwise placed in the bottom or bed 2 of a water mass, such as a sea, lake or river, wherein a section 3 of the pipeline is to be treated for repairing and/or reinforcing purposes.
  • a control operation carried out by in line inspection, external surveys or any proper control means, means may be operated from a service vessel 4 at a sea surface 5, a defect 6 may be detected in section 3 and repairing operations should be carried out to place section 3 in proper operative conditions.
  • Failure or defect 6 may be of any type such as a reduction in the wall thickness, excessive rust, bubbles appearing in the wall, a dent, a crack, a generalized corrosion, pitting, etc.
  • a repairing and/or reinforcing sleeve 7 is placed and installed around and onto section 3 as it is illustrated in Figures 2-4.
  • a cavity 8 may be made in the seabed by jetting tools that are well known in the art.
  • Section 3 is enclosed into a repairing assembly comprising sleeve 7, which sleeve may comprise a cylindrical member with sealing capacities to seal against pipeline 1.
  • sleeve 7 has an inner diameter larger than an outer diameter of the pipeline section, whereby when the sleeve is concentrically installed onto an outer surface 9 of the pipeline section, the sleeve forms a watertight annular chamber 10 around the pipeline section.
  • chamber 10 may have a thickness of about 1 cm to about 2 cm, however this value will depend on the pipeline size.
  • Sleeve 7 preferably comprises a couple of halves 11 that may be coupled together by flanges 12 and bolts 13.
  • Flanges may be arranged horizontally, as shown in the Figures, or vertically (not shown), with a half sleeve 11 arranged at each side of the pipeline.
  • Flanges 12 preferably are of triangular shape, as shown in the Figures, and bolts 13 are arranged into cavities in a manner that the ends thereof, or the nuts placed at the ends thereof remain embedded into, i.e. not protruding from, the flanges.
  • Nuts at the ends of the bolts may be protected by any sealing material 22 and a retaining or clamping bar 23 may is arranged onto flanges 12 to enclose and protect the same.
  • spacing pins or bolts 14 may be arranged as it is known in the art. Chamber will remain watertight thank to the provision of sealing means 17 that seals the halves against the outer surface of the pipeline section. Additional sealing means, not shown, may be placed between flanges 12 to provide a watertight coupling. While flanges 12 have been illustrated to join halves 11, halves 11 may be fixed and sealed in place by clamping means that may comprise iron straps, rings, collars and the like.
  • sleeve 7 also includes at least two ports 15, 16 passing through a wall of the sleeve for injecting and flowing a drying fluid into the chamber, and for injecting a resin through one or more of the ports into the dry chamber for filling the chamber.
  • ports 15, 16 may be placed one in each half or both in the same sleeve half, and they will operate indistinctly, as desired, as inlet and outlet ports, depending on the product that will be injected and/or removed in and from the chamber.
  • Ports 15, 16 preferably include any type of closing means, such as plugs, valves and the like in order to close the port and keep the chamber watertight, as will be explained below in connection to the method of the invention. 16.
  • Each port may include any fitting such as a connecting socket 18 for connecting and disconnecting at least one conduit 19, 20 that preferably extends from the sea surface and is handled from vessel or barge 4.

  • the method may be employed for repairing and/or reinforcing a section 3 of a subsea pipeline by installing sealing sleeve 7 onto an outer surface of the pipeline section, whereby watertight annular chamber 10 is defined between the outer surface of the pipeline section and the sleeve. Pins 14 preferably keep sleeve and pipeline concentrically arranged.
  • chamber is tested to control if it is watertight and then a fluid, preferably a drying fluid is injected into the chamber to dry the chamber. Finally, when the chamber is dry, a resin, preferably an epoxy resin, is injected into the chamber to fill the chamber. More particularly, once sealing semi cylindrical sleeve halves 11 have been installed onto pipeline section 3, the clamping means, such as flanges 12, have been clamped together, and the chamber has been controlled as to its watertight condition, a fluid is injected, for instance, through port 15, and the fluid is circulated through the chamber for removing any water contained therein and for drying the chamber in order to have a dry environment around the pipeline section.
