Definitions
- the present invention relates to an underwater flexible pipe for the transport of hydrocarbons in deep water.
- the flexible hydrocarbon transport pipes are already well known, and they generally comprise from the inside to the outside of the pipe, a metal carcass, an internal polymer sheath, a pressure vault, webs of traction armors and an outer sheath made of polymer to protect the entire pipe and in particular to prevent seawater from penetrating its thickness.
- the metal casing and the pressure vault consist of longitudinal elements wound with short pitch, and they give the pipe its resistance to radial forces while the plies of tensile armor consist of metal wires wound in long steps to resume axial efforts.
- the nature, number, sizing and organization of the layers constituting the flexible pipes are essentially related to their conditions of use and installation.
- the concept of short-pitch winding designates any helical winding at a helix angle close to 90 °, typically between 75 ° and 90 °.
- the concept of long-pitch winding covers helical angles less than 55 e , typically between 25 ° and 55 ° for armor plies.
- a known solution that makes it possible to reduce the risk of radial buckling in "birdcage” consists in winding, at a short pitch, around the plies of tensile armor, ribbons reinforced with aramid fibers, and more specifically homopolymer fibers PPTA.
- this abbreviation means poly-p-phenylene terephthalamide ("polyparaphenylene terephthalamide" in the English language).
- Such ribbons have a high tensile strength along their longitudinal axis, which limits the swelling of the plies of tensile armor. They also have great flexibility in bending, which facilitates the handling and winding operations around the armor layers. Finally, with equal mechanical characteristics, they are much lighter than metal tapes, which reduces the weight of the flexible pipe. In particular, reference may be made to document FR 2 837 899 in which such a conduct is disclosed.
- These reinforcing ribbons are in the form of bundles of filament strands consisting of PPTA homopolymer fibers oriented parallel to the longitudinal axis of the ribbon.
- These longitudinal filament tows can be assembled with each other under the shape of a relatively flat beam having a substantially rectangular section of the type of that of a ribbon or band. It is also possible to use a reinforcing ribbon consisting of a substantially rectangular central section and two longitudinal edges thinner than the central section as described in document EP1419338.
- the assembly and contention means of these filament tows generally comprise transverse elements which are shaped so as to surround and clamp together the said locks so as to form a relatively flat bundle.
- these transverse elements can be likened to weft threads, the filament strands forming the warp, and the tape can then be considered as a woven material.
- Various embodiments of these reinforcing tapes are described in WO97 / 12753 and WO9713091. However, it was found despite this, that under extreme conditions of use, these reinforcing tapes could deteriorate. These extreme conditions are mainly encountered when the flexible pipe is on the one hand submerged at great depth, typically more than 2000m, and on the other hand simultaneously subjected to severe dynamic bending stresses, which generates a phenomenon of fatigue ribbons reinforcement.
- a problem that arises and that aims to solve the present invention is to provide a subsea flexible pipe that can withstand in these extreme conditions of depth and dynamic stress bending, and for which the swelling of the tensile armor can be permanently contained to avoid radial buckling in "birdcage".
- the present invention proposes a submarine flexible pipe intended for the transport of hydrocarbons, said flexible pipe comprising, from the inside to the outside, an internal sealing sheath, at least one sheet of traction armor wound around said internal sealing sheath, a holding layer comprising at least one reinforcement tape wound around said tensile armor ply, and at least one tubular structure which surrounds said holding layer, said reinforcing ribbon comprising filamentary strands oriented substantially longitudinally, said filament strands comprising polymer fibers; according to the invention, said polymer fibers have, at ambient temperature, a modulus of elasticity greater than 55 GPa so that said reinforcing tape is adapted to block the radial expansion of said armor layer, when said armor layer is subjected to radial efforts; and said polymer fibers further have a tensile extension greater than 4% so that said reinforcing tape is adapted to deform without breaking.
- tape and “tape” ("tape” in English) are considered equivalent and are used interchangeably.
- filament refers to a fiber of great length.
- bond refers to a combination of the juxtaposition or assembly of several fibers or filaments.
- roving refers to the juxtaposition or the assembly of several fibers, filaments or threads. In the case of reinforcement strips according to the present invention, the assembly between son and filaments is generally achieved by a relatively small twist so as not to degrade the tensile strength along the axis of the wick.
- the above modulus of elasticity and elongation at break are measured by a tensile test in accordance with ASTM D885-04. This test is practiced not on an individual fiber, but on a thread consisting of 500 to 2500 identical fibers or filaments of the same length.
- the twist of the wire used for the test is less than 100 turns per meter and for example, of the order of 60 turns per meter, which makes it possible to improve the reproducibility and the precision of the measurements, in accordance with the recommendations of the aforementioned standard.
- the distance between the jaws at the beginning of the tensile test is of the order of 400 mm. Traction speed is of the order of 50 mm / min.
- the ambient temperature at which these tests are made is of the order of 18 ° C. to 23 ° C.
- a feature of the invention lies in the choice of a reinforcing tape whose modulus of elasticity ("tensile modulus” in English) of the polymer fibers having the reinforcing function is not necessarily very high, but whose extension to break (“elongation at break” in English) is relatively important. In this way, it is both the value of the modulus of elasticity greater than 55 GPa and the elongation at break or extension at break which must be greater than 4%, which matters.
- the retaining layer is gripped between firstly the son constituting the outer layer of tensile armor and secondly the outer tubular structure.
- the movements of the flexible pipe by generating relative displacements between the armor wires, lead to either locally stretching the retaining layer at the level of the gaps between said armor wires, or compressing it locally so that it forms folds at the level of said games.
- the repetition of these cycles of compression and ply formation generates a phenomenon of fatigue of the polymer fibers.
- the greater the extension at break of the polymer fibers of the holding layer is large, the less stretching and the folds of the holding layer between the armor wires are likely to cause the rupture of these polymer fibers. .
- the implementation of a reinforcing tape whose polymer fibers having the reinforcing function have an extension at break greater than 4%, significantly improves the fatigue strength of the holding layer.
- said polymer fibers furthermore have an extension at break, measured at ambient temperature, of greater than 4.2%. This feature provides a further improvement in the fatigue strength of the support layer.
- said polymer fibers also have a modulus of elasticity, measured at room temperature, greater than 60 GPa. This characteristic makes it possible, with an equal amount of fibers, to reduce the swelling of the holding layer in cases where the outer sheath is not waterproof.
- said polymer fibers have an extended tensile strength, measured at ambient temperature (according to ASTM D885-04) greater than 3000 MPa, so that the measurement of the area under the curve, stress / strain, which is representative of the energy that can absorb these fibers, is further increased.
- said polymer fibers furthermore have an ultimate tensile strength, measured at a temperature of 130 ° C. (according to the ASTMD885-04 standard) greater than 2300 MPa, preferably 2500 MPa.
- an ultimate tensile strength measured at a temperature of 130 ° C. (according to the ASTMD885-04 standard) greater than 2300 MPa, preferably 2500 MPa.
- the polymers of said fibers are copolymers and preferably polymers belonging to the family of aramids and more particularly aramids of para type (as opposed to the meta type).
- said polymer fibers are held together, preferably clamped against each other, so as to increase their coefficient of friction relative to each other and to increase the tensile strength of the filament tow.
- the polymers of said fibers are co-poly-p-phenylene / 3,4'-oxydiphenylene terephthalamide ("co-poly- (paraphenylene / 3,4'-oxydiphenylene terephthalamide)" in the English language).
- the reinforcing ribbon further comprises restraining means for holding together said filament strands.
- said reinforcing tape is a woven material.
- the restraining means intended to hold together the different filament strands then comprise at least one weft thread woven with said strands which constitute the chain elements. Since such weft yarns are not subjected to the tension forces applied to the strip, they can advantageously be made with a material that is not very resistant to that of the filamentary strands.
- the reinforcing tapes are wound with a short pitch, which makes it possible to increase the resistance to swelling of the holding layer.
- this winding forms contiguous turns, to make the support layer more resistant.
- the holding layer may consist of several windings superimposed on each other and optionally crossed between them. This makes it possible to produce a holding layer having a thickness greater than that of the strips.
- tubular structure advantageously comprises an outer sealing sheath which is applied to the holding layer, and which compresses it against the armor plies when the pipe is extended in the deep seabed.
- FIG. 1 is a partial schematic perspective view of a flexible pipe according to the invention.
- Figure 2 is a graph illustrating the mechanical properties of polymeric synthetic materials.
- FIG. 3 is a partial schematic perspective view of a reinforcing tape according to the invention.
- FIG. 1 illustrates a pipe according to the invention comprising, from the outside towards the inside, an outer polymeric sheath 10 (called outer sheath), a retaining layer 12 which will be detailed hereinafter around an outer layer of traction armor 14, an inner ply of traction armors 16 wound in the opposite direction of the outer ply 14, a pressure vault 20 for absorbing the radial forces generated by the pressure of the transported fluid, an internal polymeric sheath sealing 18 and an internal carcass 17 for taking up the radial forces of crushing. Due to the presence of the inner carcass 17, this pipe is said to not smooth passage ("rough bore" in English). The invention could also be applied to a so-called smooth-bore (English-speaking) pipe, having no internal carcass.
- outer sheath an outer polymeric sheath 10
- retaining layer 12 which will be detailed hereinafter around an outer layer of traction armor 14
- an inner ply of traction armors 16 wound in the opposite direction of the outer ply 14 a pressure vault 20 for absorbing the
- the scope of the present invention would not be eliminated by eliminating the pressure vault 20, provided that the helix angles of the wires constituting the armor plies 14, 16 are close to 55 ° and in the opposite direction.
- Armor plies 14, 16 are obtained by long pitch winding of a set of son of metal or composite material, generally of substantially rectangular section. The invention would also apply if these wires had a section of circular or complex geometry, of the type for example T auto-stapled.
- FIG 1 only two plies of armor 14 and 16 are shown, but the pipe could also include one or more additional pairs of armor.
- the armor ply 14 is said to be external because it is here the last, starting from the inside of the pipe, before the outer sealing sheath 10.
- the retaining layer 12 is generally wound around the outer ply 14, but the invention would also apply to the case of a holding layer interposed between two layers of tensile armor. Such a configuration is disclosed in document FR 2 837 899.
- the retaining layer 12 may consist of several strips, strips, ribbons or unitary elements wound with a short pitch around the outer armor ply 14. This winding is generally joined or overlapped so as to increase the recovery capacity of the radial inflation forces.
- the unitary elements of the holding layer have a high longitudinal tensile strength, along their longitudinal axis.
- the unitary holding elements are made of suitable materials, and in this case in a reinforcing ribbon of polymer fibers whose characteristics are specific.
- the reinforcing tape is made by woven or non-woven assembly of said fibers.
- This holding layer 12 is intended to block the radial expansion of said armor ply, when it undergoes radial forces. And this is the case when the flexible pipe, extended in a deep seabed, undergoes a significant inverse bottom effect, and the traction armor plies 14, 16 tend to swell radially under the effect of the axial compression. As long as the outer sheath 10 is sealed, the holding layer 12 has no function since the blocking of the radial swelling of the traction armor plies 14, 16 is ensured by the external hydrostatic pressure.
- the holding layer 12 must immediately block the radial expansion of the armor plies and thus prevent the formation of a fault in the form of "bird cage". Also, the retaining layer 12 must be sufficiently strong to resume the radial expansion of the tensile armor 14, 16, at the moment when a possible tearing of the outer sheath 10 occurs.
- the mechanical characteristics polymers adapted to withstand the very severe loading conditions mentioned above were not so much those of a high modulus of elasticity, but rather those of a combination of a high elongation capacity with a relatively high modulus. Such materials have at room temperature a modulus of elasticity greater than 55 GPa, advantageously greater than 60 GPa, and especially elongation at break relatively large, in practice greater than 4% and preferably greater than 4.2%.
- an anti-wear layer (“anti-wear layer” in English) of polymeric material may be interposed between the outer layer of tensile armor 16 and the holding layer 12, so as to prevent the fibers of polymer of the holding layer 12 may wear in contact with metal armor.
- Anti-wear layers which are well known to those skilled in the art, are generally made by helical winding of one or more ribbons obtained by extrusion of a polymeric material based on polyamide, polyolefins, or PVDF (" polyvinylidene fluoride ").
- WO2006 / 120320 which describes anti-wear layers consisting of polysulfone (PSU), polyethersulfone (PES), polyphenylsulfone (PPSU), polyetherimide (PEI), polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK) ribbons. or phenylene polysulfide (PPS).
- PSU polysulfone
- PES polyethersulfone
- PPSU polyphenylsulfone
- PEI polyetherimide
- PTFE polytetrafluoroethylene
- PEEK polyetheretherketone
- PPS phenylene polysulfide
- FIG. 2 illustrating the mechanical properties of the polymers adapted to form reinforcing tapes according to the invention.
- the curve 22 in broken lines illustrates the mechanical characteristics of a polymer which is not suitable for producing a reinforcing tape according to the invention, while the curve 24 in solid line is that of a polymer which is suitable.
- the curve 22 is that of polymer fibers whose modulus of elasticity E, corresponding to the slope of the first portion of curve 26, is large but whose elongation at the breaking point 28 is relatively low, here of 2.5%%.
- the curve 24 bears witness to a modulus of elasticity E corresponding to the slope of the first part of the curve 30, less important but greater than 55 GPa 1 and above all, of an elongation at the breaking point 32 greater than 4 %.
- the polymer corresponding to the Curve 22 extends much less than that corresponding to curve 24.
- the first elongates on the order of 1, 2% and the second on the order of 2%. Therefore, with equivalent loading and equivalent dimensions, a holding layer consisting of the polymer corresponding to the layer 24 inflates almost twice as much as another consisting of the polymer corresponding to the layer 22.
- the polymer fibers having a modulus of elasticity greater than 55 GPa also generally exhibit an almost linear and elastic behavior until rupture. The phase of plastic deformation just before the break is then very short, so that in practice, the elastic limit is very close to the limit at break.
- High performance polyethylene polymers are known which have both a modulus of elasticity greater than 55 GPa and an elongation at break of more than 4%. These materials can be used for the implementation of the present invention, subject however to being limited to low temperature applications, typically less than 40 ° C. In fact, the melting temperature of the polyethylene fibers is of the order of 150 0 C, so that above a temperature of 50 ° C, creep phenomena and falling mechanical characteristics greatly degrade their performance.
- aramid polymers it is more advantageous to use aramid polymers because they have a much better temperature behavior, especially around 130 0 C, which is the maximum temperature that, given the current technologies, can endure a conduct flexible hydrocarbon transport.
- the melting temperature of the aramid fibers is very high, of the order of 500 0 C. Therefore, they do not degrade at temperatures below 13O 0 C 1 and retain these essential temperatures their mechanical characteristics .
- some of these fibers have a tensile strength greater than 2700 MPa at 80 ° C. and 2300 MPa at 130 ° C., which allows their use in flexible pipes intended for the transport of hydrocarbons at 130 ° C. .
- copolymers generally have a lower crystallinity level than the PPTA homopolymers, which gives them a greater capacity to absorb deformations of large amplitude while retaining their essential mechanical properties.
- FIG. 3 illustrates an example of reinforcing tape 34 according to the invention.
- the ribbon 34 comprises several filament strands 36 oriented longitudinally with respect to its axis.
- the locks 36 are consisting of assembling yarns, filaments or fibers 38 made of a polymeric material according to the present invention.
- the locks 36 are juxtaposed and held together by restraining means 40, 42 oriented transversely to the axis of the ribbon 34.
- These restraining means may comprise links 42 surrounding the assembly, or weft threads 40 woven with the filament strands 36, the latter then constituting the warp elements. Since the restraining means do not have the function of taking up longitudinal tensile forces, they can be made with polymers that are less resistant than those used for filament strands 36.
