Definitions

  • the present invention relates to flexible pipe of the type suitable for transportation of production fluids.
  • the present invention relates to a method of supporting a flexible pipe so that an amount of support provided to the flexible pipe is varied responsive to changes in one or more conditions experienced by the flexible pipe.
  • Flexible pipe is utilised to transport production fluids, such as oil and/or gas and/or water, from one location to another.
  • Flexible pipe is particularly useful in connecting a sub-sea location to a sea level location.
  • Flexible pipe is generally formed as an assembly of a flexible pipe body and one or more end fittings.
  • the pipe body is typically formed as a composite of layered materials that form a fluid and pressure-containing conduit.
  • the pipe structure allows large deflections without causing bending stresses that impair the pipe's functionality over its lifetime.
  • the pipe body is generally, but not necessarily, built up as a composite structure including metallic and polymer layers.
  • Flexible pipe may be utilised as a flowline. Under certain conditions the pipe is required to remain at a controlled height above a sea bed. For example, when bridging unstable, aggressive environmentally sensitive or active sea bed conditions. This is currently difficult to achieve with known techniques.
  • a flexible riser is a flexible pipe used to connect a compliant top side structural system with a sea bed location.
  • a flexible riser system can be designed for many types of floating production structures and some well known riser configurations are free hanging catenary risers, lazy “S” risers, lazy “wave” risers, steep “wave” risers or the like. Such configurations are selectively suitable for use in shallow, medium, deep or ultra deep water depths.
  • a flexible pipe riser is subjected to dynamic loading due to a number of possible conditions, for example due to motion of a vessel or platform on a surface of sea. Surge motion and heave motion of such surface bound vessel can particularly cause curvature changes in a riser configuration. It is generally advantageous to prevent shape changes or control such changes within predetermined limits.
  • buoyancy modules at selected regions of the riser, for example near a top section, or in the middle, or near the touch down region.
  • riser configuration When utilising a wave configuration of riser problems can occur due to the attached buoyancy elements.
  • the riser configuration may float at the water surface or sink to a sea bed region due to sensitivity to content density change.
  • the depth of a riser system may vary due to internal fluid density changes or external environmental changes in non-shallow water environments use of risers with buoyancy aids has been limited.
  • a method of supporting a flexible pipe comprising the steps of:
  • a flexible pipe for transporting production fluids comprising:
  • Embodiments of the present invention provide a practical solution for shallow water applications of a flexible riser wave configuration where the riser configuration may otherwise either float at the water surface or sink to the sea bed due to sensitivity to content density change.
  • Embodiments of the present invention provide the advantage of low installation costs and short installation times associated with wave configurations and yet provide the performance advantage enjoyed by an S wave riser configuration.
  • Embodiments of the present invention provide a riser suitable for use where the depth of the riser system may vary due to internal fluid density changes and/or external environmental changes. Such a compliant system is beneficial at any range of water depths. In this way the height of the flexible pipe above a sea bed or a shape adopted by the flexible pipe can be controlled.
  • FIG. 1 illustrates flexible pipe body
  • FIG. 2 illustrates a wave configuration riser
  • FIG. 3 illustrates control of height above a sea bed for a flexible pipe flowline.
  • FIG. 1 illustrates how a pipe body 100 is formed in accordance with an embodiment of the present invention from a composite of layered materials that form a pressure-containing conduit. Although a number of particular layers are illustrated in FIG. 1 , it is to be understood that the present invention is broadly applicable to composite pipe body structures including two or more layers. It is to be further noted that the layer thicknesses are shown for illustrative purposes only.
  • pipe body typically includes an innermost carcass layer 101 .
  • the carcass provides an interlocked metallic construction that can be used as the innermost layer to prevent, totally or partially, collapse of an internal pressure sheath 102 due to pipe decompression, external pressure, tensile armour pressure and mechanical crushing loads. It will be appreciated that embodiments of the present invention are applicable to ‘smooth bore’ as well as such ‘rough bore’ applications.
  • the internal pressure sheath 102 acts as a fluid retaining layer and typically comprises a polymer layer that ensures internal-fluid integrity. It is to be understood that this layer may itself comprise a number of sub-layers. It will be appreciated that when the optional carcass layer is utilised the internal pressure sheath is often referred to as a barrier layer. In operation without such a carcass (so-called smooth-bore operation) the internal pressure sheath may be referred to as a liner.
  • a pressure armour layer 103 is a structural layer with a lay angle close to 90° that increases the resistance of the flexible pipe to internal and external pressure and mechanical crushing loads.
  • the layer also structurally supports the internal-pressure sheath and typically consists of an interlocked metallic construction.
  • the flexible pipe body may also include one or more layers of tape 104 and a first tensile armour layer 105 and second tensile armour layer 106 .
  • Each tensile armour layer is a structural layer with a lay angle typically between 20° and 55°. Each layer is used to sustain tensile loads and internal pressure.
  • the tensile armour layers are typically counter-wound in pairs.
  • the flexible pipe body also typically includes an outer sheath 107 which comprises a polymer layer used to protect the pipe against penetration of seawater and other external environments, corrosion, abrasion and mechanical damage.
  • an outer sheath 107 which comprises a polymer layer used to protect the pipe against penetration of seawater and other external environments, corrosion, abrasion and mechanical damage.
  • One or more layers 108 of insulation may also be included.
  • Each flexible pipe comprises at least one portion, sometimes referred to as a segment or section of pipe body 100 together with an end fitting located at least one end of the flexible pipe.
  • An end fitting provides a mechanical device which forms the transition between the flexible pipe body and a connector.
  • the different pipe layers as shown, for example, in FIG. 1 are terminated in the end fitting in such a way as to transfer the load between the flexible pipe and the connector.
  • FIG. 2 illustrates a riser assembly 200 suitable for transporting production fluid such as oil and/or gas and/or water from a sub-sea location 201 to a floating facility 202 .
  • the sub-sea location 201 is a connection to a sub-sea flow line.
  • the flexible flow line comprises a flexible pipe, wholly or in part, resting on the sea floor 203 or buried below the sea floor.
  • the floating facility may be provided by a platform and/or buoy or, as illustrated in FIG. 2 , a ship.
  • the riser 200 is provided as a flexible riser, that is to say a flexible pipe connecting the ship to the sea floor installation.
  • the riser assembly 200 illustrated in FIG. 2 is arranged in a wave configuration.
  • the solid line illustrates a steep wave configuration riser whilst the dotted line 204 illustrates a lazy wave configuration.
  • the shape adopted by the riser is determined by the buoyancy modules 205 secured along its length.
  • at least one wave consisting of a crest region 206 and a valley region 207 is formed between the touch down region around the sub-sea location 201 and the floating vessel 202 . It will be appreciated that embodiments of the present invention are applicable to one or more wave regions in a riser.
  • Each buoyancy module 205 provides extra buoyancy to the flexible pipe.
  • Buoyancy modules are known to those skilled in the art and may be secured to the flexible pipe in a variety of known ways.
  • weight chains 208 consisting of a length of interlocked links are secured to a number of the buoyancy modules.
  • a weight chain 208 may be secured to each buoyancy module secured to the riser or may be selectively secured to only one or more of the buoyancy modules.
  • the weight associated with the mass of chain in the length of chain counteracts the buoyancy provided by the buoyancy module to which the weight chain is secured and the inherent buoyancy of the flexible pipe.
  • a section 209 of the weight chain 208 hangs freely downwardly from the buoyancy module towards the sea bed 203 .
  • a further portion 210 of the weight chain rests upon the surface of the sea bed 203 .
  • a part of the weight chain is laid on the sea bed.
  • the buoyancy When the riser content density increases the buoyancy will be balanced by reduced chain weight as the additional chain is laid on the sea bed. In this way the support provided to the flexible pipe is automatically and continually adjusted so as to maintain the flexible pipe in a desired configuration or at least in a configuration within predetermined threshold limits.
  • a top section 211 of a weight chain may be replaced or provided by an alternative flexible filament such as a synthetic rope, wire, cable or the like.
  • a weight chain 212 is secured at a lower end region of the filament 211 so that again a portion of the weight chain rests upon the sea bed.
  • weight chain 213 which may be secured directly to the flexible pipe rather than to a buoyancy module.
  • buoyancy modules may be selected together with the weights of the weight chains attached so as to optimise performance.
  • the applied buoyancy modules help determine that the configuration always remains in a floating state even when the pipe weight reaches its heaviest possible state, for example due to marine growth, buoyancy loss, content density change and the weight of suspended chains.
  • the weight chains themselves may be trimmed at the sea bed during installation to ensure that a section of the chains remains on the sea bed at the lightest riser configuration. The length of the chain on the sea bed will be determined for the largest potential change, for example in the riser contents.
  • FIG. 3 illustrates an alternative use of embodiments of the present invention in which support is provided to flexible pipe 300 arranged as a flowline 300 .
  • the flowline is provided with supports so as to ensure that a height h above the sea bed 203 is maintained at a fixed distance or at least within a range of distances.
  • Embodiments of the present invention are particularly useful when a pipe is to span unfavourable or environmentally sensitive sea bed conditions in shallow, deep or ultra-deep water applications.
  • an area of coral 301 can be successfully bridged so that neither the coral or flexible pipe comes into contact.
  • one or more tethers 302 are utilised to fix the lateral position of the flowline 300 .
  • the system of the weight chain and inherent buoyancy or additional buoyancy modules acts as a self-buoyancy/weight adjusting device for automatically maintaining a working flexible pipe flowline, jumper or riser configuration.
  • the system progressively mobilises additional weight as one or more chains are lifted off the sea bed as the weight of pipe contents reduces.
  • the amount of buoyancy added to compensate for the weight of the chain may be reduced by replacing an upper (non-active) length of chain with wire or synthetic rope or the like.
  • the system may be used for any circumstance where a flexible pipe is required to remain at a controlled height above the sea bed or in a controlled shape above the sea bed. This is possible under wave configuration riser conditions or where a flowline must bridge unstable, aggressive, environmentally sensitive or active sea bed conditions.
  • the variation of support provided to a flexible pipe may be controlled in a wide variety of ways not necessarily including weight and buoyancy elements but rather by biasing elements such, as springs, elastic elements or similar means.
  • biasing elements such, as springs, elastic elements or similar means.
  • an alternative could be any self righting or self adjusting member which is attached to the pipe or pipe ancillaries in order to adjust the downward force experienced by the pipe. This could be:
