Definitions

  • the present invention relates to a monitoring apparatus and method.
  • the present invention relates to the monitoring of strain or load in a flexible riser installation for transporting production fluids such as oil and gas.
  • 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 (which may be deep underwater, say 1000 metres or more) to a sea level location.
  • the pipe may have an internal diameter of typically up to around 0.6 metres.
  • 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 combination of layered materials that form a 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 built up as a combined structure including metallic and polymer layers.
  • a flexible pipe is an assembly of a portion of a pipe body and one or more end fittings in each of which a respective end of the pipe body is terminated.
  • Fig. 1 illustrates how pipe body 100 may be formed from a combination of layered materials that form a pressure- containing conduit. Although a number of particular layers are illustrated in Fig. 1 , pipe body structures may include two or more coaxial layers manufactured from a variety of possible materials. For example, the pipe body may be formed from metallic layers, composite layers, or a combination of different materials. The layer thicknesses are shown for illustrative purposes only.
  • a pipe body includes an optional innermost carcass layer 101.
  • the carcass provides an interlocked 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, and tensile armour pressure and mechanical crushing loads.
  • the carcass layer is often a metallic layer, formed from stainless steel, for example.
  • the carcass layer could also be formed from composite, polymer, or other material, or a combination of materials.
  • Pipe body may be used without a carcass layer (i.e. smooth bore) or with a carcass (rough bore).
  • the internal pressure sheath 102 acts as a fluid retaining layer and comprises a polymer layer that ensures internal fluid integrity.
  • 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 by those skilled in the art as a barrier layer. In operation without such a carcass (smooth bore operation) the internal pressure sheath may be referred to as a liner.
  • An optional pressure armour layer 103 is a structural layer 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 may be formed as an interlocked construction of wires wound with a lay angle close to 90°.
  • the pressure armour layer is often a metallic layer, formed from carbon steel, for example.
  • the pressure armour layer could also be formed from composite, polymer, or other material, or a combination of materials.
  • the flexible pipe body also includes an optional first tensile armour layer 105 and optional second tensile armour layer 106.
  • Each tensile armour layer is used to sustain tensile loads and internal pressure.
  • the tensile armour layer is often formed from a plurality of metallic wires (to impart strength to the layer) that are located over an inner layer and are helically wound along the length of the pipe at a lay angle typically between about 10° to 55°.
  • the tensile armour layers are often counter-wound in pairs.
  • the tensile armour layers are often metallic layers, formed from carbon steel, for example.
  • the tensile armour layers could also be formed from composite, polymer, or other material, or a combination of materials.
  • the flexible pipe body also typically includes optional layers of insulation 107 and an outer sheath 108, which comprises a polymer layer used to protect the pipe against penetration of seawater and other external environments, corrosion, abrasion and mechanical damage.
  • 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 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.
  • the end fittings of a flexible pipe may be used for connecting segments of flexible pipe body together or for connecting them to terminal equipment such as a rigid sub-sea structures or floating facilities.
  • flexible pipe can be used to provide a riser assembly for transporting fluids from a sub-sea flow line to a floating structure.
  • 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.
  • a flexible flow line 205 comprises a flexible pipe, wholly or in part, resting on the sea floor 204 or buried below the sea floor and used in a static application.
  • the floating facility may be provided by a platform and/or buoy or, as illustrated in Fig. 2, a ship.
  • the riser assembly 200 is provided as a flexible riser, that is to say a flexible pipe 203 connecting the ship to the sea floor installation.
  • FIG. 3 A cross-section of a known end fitting 300, such as disclosed in WO2007/144552 or EP1867907, is shown in Figure 3.
  • the end fitting 300 includes an end fitting body 301 , which includes an internal bore 302 running along its length, and a jacket or casing 305, which is secured via one or more bolt or other such securing mechanism to the end fitting body.
  • the jacket acts as a housing and is sealed to the outer sheath 108 of the flexible pipe body via an outer sealing ring 309.
  • the end fitting body is made from steel or other such rigid material.
  • At a first end of the end fitting body 301 there is defined an open mouth region 303 into which an end of a segment of flexible pipe body 100 is located and then terminated.
  • a connector 304 At a further end of the end fitting body 301 is a connector 304.
  • This is formed as a substantially disk-like flared region on the end fitting body.
  • the connector can be connected directly to a matching connector of a further end fitting body of an adjacent segment of flexible pipe. This can be done using bolts or some other form of securing mechanism. In such a configuration the end fittings would be located in a back-to-back configuration. This may be termed an intermediate connection or midline connection.
  • the connector 304 may be connected to a floating or stationary structure such as a ship, platform or other such structure.
  • the end fitting would have a hang off assembly added to enable the pipe to structurally locate at the moon pool of the vessel, or equivalent position on a platform, etc.
  • the term end fitting assembly is used to describe either an end fitting or an end fitting plus any ancillary components such as a hang off.
  • Various layers of flexible pipe body are introduced to the end fitting assembly, cut to appropriate length, and sealingly engaged with a particular portion of the end fitting.
  • An end fitting assembly may form part of either a top connection (hang off point) or a midline connection.
  • an end fitting assembly In use, an end fitting assembly is subject to various forces including high tension and compressions loads, for example. These forces can be due to environmental factors including temperature and pressure fluctuations and underwater currents.
  • the weight of a flexible pipe terminated in an end fitting can also cause increased stresses and strains in the end fitting assembly.
  • WO 2009/109745 discloses a fatigue monitoring system adapted to be fit onto a flexible pipe system having a bend stiffener, and having instrumentation to monitor fatigue close to the bend stiffener.
  • the fatigue monitoring system is operable to determine pipe fatigue near the bend stiffener during use.
  • the system comprises a composite sleeve that is clamped onto the flexible pipe and as such the sleeve itself could cause extra stress on the pipe.
  • an apparatus for monitoring strain in a flexible riser comprising at least one sensor for measuring a mechanical parameter of the flexible riser, the at least one sensor operably connected to an end fitting assembly of the flexible riser and arranged to provide data corresponding to the parameter to a data acquisition system.

  • Certain embodiments of the invention provide the advantage that real time monitoring of particular areas of a flexible pipe may be provided. Certain embodiments provide the advantage that data may be generated that is representative of actual field data, enabling a reduction in conservatism in the design of pipe layers for controlling tension, and thus enabling lighter and more cost effective pipe structures to be designed.
