    INSTALLATION FOR THE MANUFACTURE OF A REINFORCEMENT STRUCTURE
    FLEXIBLE CONDUCT, ASSOCIATED METHOD AND SYSTEM INCLUDING
    THE SAID INSTALLATION
    DESCRIPTION
    Technical field of the invention
    The invention relates to an installation for the manufacture of a reinforcement structure of a flexible pipe for the transport of an oil and / or gas fluid in an underwater environment, the associated method and a system comprising said installation.
    More particularly, a field of application envisaged is the manufacture of an internal carcass and / or of an underwater flexible pipe pressure vault intended for the transport of petroleum and / or gas fluid.
    State of the art
    In general, flexible pipes for the transport of an oil and / or gas fluid in an underwater environment are immersed in a body of water at depths that can exceed 3000 m. They find their particular interest in the routing of petroleum and / or gas fluid between a bottom installation and a surface installation. They can also be used to connect two downhole installations. Certain flexible pipes can also be used to connect two surface installations.
    The structure of a flexible pipe is widely known in the prior art and is notably described in the normative documents API RP 17B, 5 th edition, published in May 2014 and API 17J, 4 th edition, published in May 2014 by l 'American Petroleum Institute.
    Typically, a flexible pipe comprises an internal sealing sheath more commonly called “pressure sheath” (“pressure sheath” in English) defining an internal passage for the circulation of petroleum and / or gas fluid.
    Significant tensile forces can be exerted on the flexible pipe, especially when it extends through deep bodies of water. A sheet of tensile armor is then generally arranged around the flexible pipe in order to take up these tensile forces. The tensile armor ply is generally composed of a plurality of layers of metal elements, generally two, wound in a helix.
    In order to prevent corrosion of these metallic elements by the water in the body of water, an external polymeric protective sheath is generally arranged around the flexible pipe.
    In addition, the flexible pipe is also subjected to a very high external pressure when it is submerged at great depth, for example 250 bar when the pipe is submerged at 2500 m depth. When this external pressure becomes significantly higher than the internal pressure, there is a risk of collapse of the flexible pipe. In addition, the transported petroleum and / or gas fluid is composed, in addition to oils and solid particles, of gases such as carbon dioxide (CO2) and hydrogen disulfide (H2S). These gases tend to diffuse through the internal sealing sheath and to accumulate within the space formed by the internal sealing sheath and the external protective layer, called "annular space", thus causing the increase pressure within said annular space. When the internal passage of the flexible pipe is subjected to rapid decompression, for example during a sudden stop of production (called "shut down" in English), the gases contained within the annular space have no time to diffuse to the internal passage of the flexible pipe. As a result, the pressure within the annular space can become greater than the internal pressure and thus lead to the collapse of the internal sealing sheath. To prevent these risks of collapse, a reinforcing structure is generally placed inside the flexible pipe. This internal reinforcement structure, more commonly known as a carcass or internal carcass, comprises a main profile wound with an helix angle of an absolute value close to 90 °. In general, the section of the main profile is S-shaped. Thus, each of the turns of the main profile cooperates with an adjacent turn thus forming the stapling of the main profile. The carcass thus gives the flexible pipe resistance to collapse.
    Furthermore, there are gaps between each turn opening out towards the inside of the flexible pipe giving the internal surface of said flexible pipe a rough appearance. The flexible pipes comprising a carcass are then said to have a non-smooth passage (called "rough bore" in English). The presence of the joints leads to pressure fluctuations in the flow of petroleum and / or gas fluid resulting in vibratory phenomena, or even, when a resonance is reached, in pulsation phenomena induced by the circulation of the fluid (called "flow induced pulsation "in English). The pulsations induced by the circulation of the fluid are likely to promote the fatigue of the related equipment to which the flexible conduits are connected as well as the fatigue of the connection means between said flexible conduits (welds, flanges, etc.). However, premature fatigue of related equipment and / or connection means can lead to disasters which can have serious consequences, both human and economic.
    One of the solutions making it possible to overcome the above-mentioned drawbacks consists in filling the gaps in the carcass of the flexible pipe in order to avoid pressure differentials during the flow of petroleum and / or gas fluid. To this end, one of the strategies consists in providing a carcass in which the gaps formed in the main profile are filled with an additional profile. More particularly, the winding pitch and the section of the additional profile make it possible to fill these gaps. The additional profile, for example, has a T or S-shaped section and is inserted into the gaps. We can in particular refer to patent applications WO2015 / 121424 and WO2015 / 121316 of the present Applicant in which such embodiments of the carcass are exemplified.
    The implementation of a carcass comprising a main profile and an additional profile to fill the gaps remains problematic. Patent application WO2015 / 121424 proposes for example to use a single installation comprising two profiling trains arranged on the same turntable allowing the shaping of metal strips intended to form the carcass. The two profiling trains are, according to the embodiments described in patent application WO2015 / 121424, superimposed or diametrically opposite with respect to the turntable. Then, downstream of the profiling trains, the main profile and the additional profile are combined and bent around a mandrel to form the carcass. The main profile and the additional profile combined are in particular pushed to the mandrel by means of drive members located downstream from the profiling trains. The drive members include two rotationally driven rollers between which the combined main profile and the additional profile are received and pushed to the mandrel.
    The presence of drive components downstream from the profiling trains intended to push the main profile and the additional profile can lead to assembly problems of the carcass. Indeed, downstream of the profiling trains, and in particular on the mandrel, there is a speed differential between the main profile and the additional profile. The additional profile is curved around the mandrel and constitutes the innermost layer of the carcass. The main profile is curved around the additional profile and constitutes the outermost layer of the carcass. Thus, the distance traveled around the mandrel and the length of the additional profile around the mandrel is less than the distance and the length of the main profile. However, upstream of the mandrel, the drive members, together, push the main profile and the additional profile with the same speed. Thus, the insertion of the additional profile within the turns formed by the main profile on the mandrel is not done correctly. Consequently, geometric defects in the reinforcement structure can result from such an installation, and thus reduce the mechanical performance of the reinforcement structure.
    Also, in combination or as an alternative to the carcass, the flexible pipe may include a reinforcing structure arranged around the internal sealing sheath. Indeed, in the case in particular where the pressure of the fluid flowing in the flexible pipe can be sufficiently high, a reinforcing structure is added in order to prevent the internal sealing sheath from bursting. This type of reinforcement structure is known in the field of the present invention under the terms of “pressure vault” (“pressure vault” in English). Typically, the pressure vault comprises a main profile, generally metallic, having a complex section and wound around the internal sealing sheath in a short pitch, that is to say with a helix angle whose absolute value is close 90 °. Between two adjacent turns formed by the winding of the main profile, there is a gap opening towards the internal space of the flexible pipe. The presence of such a gap can cause the deformation of the internal sealing sheath which can result in a premature loss of sealing. Indeed, under the effect of internal pressure, the internal sealing sheath can creep within the gaps formed by the pressure vault. In order to limit this creep phenomenon of the internal sealing sheath, the pressure vault comprises an additional profile, generally metallic, which makes it possible to fill the gap. The additional profile has for example a T-shaped section formed by profiling.
    The implementation of a pressure vault comprising a main profile and an additional profile also remains problematic in the image of the implementation of the carcass.
    There is therefore a need to provide an installation allowing the manufacture of a reinforcement structure of a flexible pipe for the transport of an oil and / or gas fluid in an underwater environment minimizing the risks of geometric defects in the structure of reinforcement.
    Disclosure of invention
    To this end, the invention proposes an installation for the manufacture of a reinforcement structure of a flexible pipe for the transport of an oil and / or gas fluid in an underwater environment comprising a tray on which is arranged:
    a first profiling train for a main strip comprising at least one main profiling head configured to receive said main strip, said at least one main profiling head comprising at least one pair of lower and upper main rollers capable of bending said strip main to form a main profile,
    - a second profiling train for an additional strip comprising at least one additional profiling head configured to receive said additional strip, said at least one additional profiling head comprising at least one pair of lower and upper additional rollers capable of folding said strip additional to form an additional profile,
    - a means for driving said at least one main profiling head, a means for winding the main profile and the additional profile downstream of said first profiling train and said second profiling train.
    The installation according to the invention is remarkable in that the pair or pairs of additional lower and upper rollers of said or all of said additional profiling heads are mounted to rotate freely relative to said plate.
    Indeed, the Applicant has highlighted an important parameter in the manufacture of such a reinforcement structure which is the speed differential between the main profile and the additional profile and therefore between the main strip and the additional strip. In fact, poor control of this speed differential can cause geometric instability of the reinforcement structure and consequently limit the resistance to the radial forces of said reinforcement structure. This speed differential is controlled in the installation according to the invention by driving only the main prolilation head (s). The pair or pairs of additional rollers of the additional profiling head or heads are mounted to rotate freely. Therefore, the additional strip and therefore the additional profile is pulled by the main profile, which allows to precisely control and adjust the speed at which the additional profile arrives on the winding means. This results in an additional profile tension and length adapted so that the latter is inserted into the turns formed by the main profile optimally. As a result, the geometric defects of the reinforcing structure are reduced or even eliminated and the mechanical resistance of the reinforcing structure is then improved.
    According to a particularly advantageous characteristic of the invention, the main profiling head is configured to receive a thickness (e1) of the main strip and the additional profiling head is configured to receive a thickness (e2) of the additional strip, said thickness (e1 ) being equal to or greater than said thickness (e2). Indeed, the main strip according to this embodiment is thicker than the additional strip. Also, the thickness of the main profile and generally greater than the thickness of the additional profile. The effort to drive the additional profile through the main profile is reduced compared to the effort that would have been exerted in the context of training an additional profile thicker than the main profile. Thus, the risk of the main section buckling downstream of the first profiling train is reduced as soon as the effort to be used to pull the additional section is reduced. These risks of buckling are all the more reduced as the compressive force is exerted on the main strip, which is the thickest strip. In addition, the main profile generally has a more complex section than that of the additional profile. The efforts to fold the main strip according to the desired section are therefore generally greater than those used to fold the additional strip. Thus, the risks of damaging the main profile by pulling downstream of the first profiling train are greater than by pulling on the additional profile. In order to maintain the integrity of the main profile, it is therefore preferable to push it in and pull the additional profile.
    In addition, according to a particularly advantageous characteristic of the invention, the pair of additional lower and upper rollers is capable of bending the additional strip in an S or T-shaped section. The profiling of the additional strip by the additional rollers in one S or T-shaped section allows to form an additional profile insertable within the gaps formed by the stapling of the main profile.
    According to an advantageous characteristic of the invention making it possible to reduce the size of the tray, the lower and / or upper main roller is respectively arranged in the axis of the lower and / or upper additional roller. In fact, according to this particular embodiment of the invention, the first profiling train and the second profiling train share the same frames and the same shafts on which the main and additional profiling head or heads are mounted. The modifications to be planned on the plate are minor and the preexisting reinforcement structure manufacturing installations can thus be easily modified to receive the second profiling train.
    Preferably, the plate is movable in rotation about its axis, which makes it possible to produce a very long reinforcement structure by helical winding of the profiles from the profiling trains. In addition, preferably, the installation also includes a means for driving the plate in rotation, for example an electric motor. The means for driving the plate in rotation not only makes it possible to continuously produce a very long reinforcement structure, but also to reduce the forces exerted by the two profiling trains by assisting them in particular during the bending of the two profiles downstream of the profiling trains, which facilitates the winding of these two strips by the winding means to form the reinforcing structure.
    Furthermore, when the reinforcing structure is for example a carcass, this constitutes the innermost layer of the flexible pipe and thus has no mechanical support of support. However, significant radial forces can be exerted on the reinforcing structure during its winding. Thus, in order to avoid the collapse of the reinforcing structure, the winding means advantageously comprises a support member intended to support the main profile and the additional profile downstream of the first and second profiling train.
    Preferably, the support member comprises a mandrel movable around its axis. This makes it easier to release the reinforcing structure from the mandrel without jamming or seizing the additional profile on the mandrel.
    Preferably, the installation comprises a device for driving the mandrel making it possible to drive said mandrel at a speed of rotation at least forty times lower than the speed of rotation of the plate. Too high a speed of rotation of the mandrel risks damaging the reinforcement structure as well as the mandrel by friction and heating resulting from the sliding movement of the reinforcement structure against the mandrel. With a speed of rotation of the mandrel at least forty times lower than the speed of rotation of the plate, on the other hand, it is possible to limit heating caused by friction between the reinforcing structure and the mandrel. Consequently, it is possible to release the reinforcing structure without damaging the equipment or the reinforcing structure.
    Preferably, the winding means comprises a plurality of plating members arranged around the support member making it possible to press and optionally bend the main profile and the additional profile around the support member, thus facilitating its assembly.
    Preferably, the installation comprises a main reel of the main strip and a secondary reel of the additional strip, said main and secondary reels being arranged on the plate upstream of the first and second profiling train. This simplifies the main and additional strip supply during the manufacture of the reinforcing structure compared to an installation in which the main and additional strip supply is carried out upstream of the installation.
    The invention also relates to a system for manufacturing a flexible pipe comprising an installation for manufacturing a reinforcement structure as mentioned above, a device for manufacturing an internal sealing sheath, a device for manufacturing a 'a sheet of tensile armor. The system has all of the above advantages.
    The invention also relates to a method for implementing an installation for manufacturing a reinforcement structure of a flexible pipe for transporting an oil and / or gas fluid in an underwater environment comprising the steps following:
    (a) arranging a first profiling train of a main strip on a plate, said first profiling train comprising at least one main profiling head comprising at least one pair of lower and upper main rollers capable of bending said main strip, ( b) arranging a second profiling train for an additional strip on said plate, said second profiling train comprising at least one additional profiling head comprising at least one pair of additional lower and upper rollers capable of folding said additional strip, said pair of additional lower and upper rollers being mounted to rotate freely, (c) driving said at least one main profiling head, (d) profiling said main strip within said first profiling train to form a main profile and said additional strip within said second profiling train to form an additional profile, (e) Wind said main profile and said additional profile around a winding means to form said reinforcing structure.
    The steps of the method are simplified insofar as only the profiling train is coupled to the drive device and that no additional drive means downstream from the first and second profiling train is necessary.

    Preferred Modes of Carrying Out the Invention
    A flexible pipe (2) for transporting an oil and / or gas fluid in an underwater environment is for example shown in FIG. 1. Such a flexible pipe (2) is notably described in the normative documents API RP 17B, 5th edition, published in May 2014 and API 17J, 4 th edition, published in May 2014 by the American Petroleum Institute.
    The flexible pipe (2) extends for example between a downhole installation and a surface installation, between two downhole installations or between two surface installations. The downhole installation is for example a collector (known as a "manifold" in English). The surface installation can be a floating storage and unloading unit generally called FPSO ("Floating Production Storage and Offloading"), a lattice-like structure ("jacket" in English) or an unloading buoy.
    The underwater environment in which the flexible pipe (2) is intended to be installed may be a lake, a sea or an ocean. The depth of the seabed can be around 100 m, 1000 m, 2000 m, or even more than 3000 m.
    The flexible pipe (2) typically comprises an internal sealing sheath (3) forming a sealed internal passage for the circulation of petroleum and / or gas fluid. The internal sealing sheath (3) is generally formed from a polymer such as a polyolefin of the polyethylene (PE), high density polyethylene (HDPE) type or from a polyamide such as a polyamide 11 (PA11) or polyamide. 12 (PA12) or a fluoropolymer of the polyvinylidene fluoride (PVDF) type. The thickness of the internal sealing sheath (3) is for example between 5 mm and 20 mm. It is generally carried out by extrusion.
    In addition, the flexible pipe (2) generally comprises at least one sheet of tensile armor (5) intended to take up the tensile forces linked mainly to the weight of the flexible pipe (2). The tensile armor ply (5) generally comprises two layers of tensile armor (6, 7) formed from a plurality of armor wires wound in a long pitch around the flexible pipe (2). By "coiled in long pitch", it is understood that the absolute value of the helix angle is less than 60 °, and is typically between 25 ° and 55 °. The armor wires can be metallic or composite formed from carbon fiber in order to reduce the total weight of the flexible pipe (2). The section of the armor wires is for example rectangular, circular or any other section suitable for the present application.
    To protect the tensile armor ply (5) from corrosion, the flexible pipe (2) may include an external protective sheath (9) arranged around the tensile armor ply (5). The external protective sheath (9) generally comprises a polymeric material such as a polyolefin of the polypropylene (PP) or polyethylene (PE) type, a polyamide (PA) or any other material suitable for the present application. The thickness of the external protective sheath (9) is for example between 5 mm and 15 mm and it is generally produced by extrusion.
    Between the tensile armor ply (5) and the external protective sheath (9), the flexible pipe (2) may possibly include a set of electrical and / or optical cables (not shown) allowing the heating and the control of the temperature of the flexible pipe (2) and / or of tubes for injecting gas, water or any other type of fluid. Such a flexible pipe (2) is notably known in the field of the present invention under the acronym IPB ("Integrated Production Bundle" in English).
    In addition, the flexible pipe (2) comprises at least one reinforcing structure (8) making it possible to take up the radial forces exerted on the flexible pipe (2). The flexible pipe (2) shown in Figure 1 comprises for example two reinforcing structures (8). The reinforcing structure (8) is a flexible tubular element arranged coaxially around and / or inside the internal sealing sheath (3).
    Referring to Figures 2 and 3, the reinforcement structure (8) comprises a main section (8a) wound in short pitch, that is to say that the absolute value of the helix angle is close to 90 ° , generally between 75 ° and 90 °. Each turn of the main profile (8a) is stapled to an adjacent turn to take up the radial forces exerted on the flexible pipe (2). The main section (8a) is generally metallic and has a thickness generally between 1 mm and 6 mm and in particular between 1.5 mm and 4 mm.
    After stapling, the turns of the main profile (8a) define a gap (80) allowing the flexibility of the flexible pipe (2) to be ensured. This gap is partially or even completely closed by an additional profile (8b). The additional profile (8b) is generally metallic and has an S or T-shaped section insertable at the level of the gap (80) of the main profile (8a).
    The thickness of the main profile (8a) is generally equal to or greater than the thickness of the additional profile (8b). For example, the additional profile (8b) has a thickness between 0.5 mm and 5 mm and more particularly between 0.8 mm and 1.5 mm.
    Figure 2 shows a first example of a reinforcing structure (8). According to this first example, the reinforcing structure (8) is arranged inside the internal sealing sheath (3) and thus constitutes the innermost layer of the flexible pipe (2). The reinforcing structure (8) is then intended to come into contact with the petroleum and / or gas fluid. Such a reinforcing structure (8) is known in the field of the present invention under the term of carcass or internal carcass. The flexible pipe (2) is subjected to a very high external pressure when it is immersed at great depth, for example around 250 bar at 2500 m depth, which can lead to risks of collapse ("collapse" in English). ) of the flexible pipe (2). Also, the internal sealing sheath (3) and the external protective sheath (9) form an annular space in which fine particles of gas contained in the oil and / or gas fluid tend to migrate through the internal sheath. sealing (3). During a possible abrupt depressurization of the flexible pipe (2) ("shut down" in English), the gases are trapped within the annular space causing an increase in pressure within said annular space. This pressure can in certain cases become higher than the pressure inside the flexible pipe (2) and lead to the collapse of the internal sealing sheath (3). In order to limit these risks of collapse, the reinforcing structure (8) is arranged inside the flexible pipe.
    According to this first example and with reference to Figure 2, the main profile (8a) has an S-shaped section. After stapling, the turns define a gap (80) opening radially inwardly of the flexible pipe (2) giving a rough appearance to the internal surface of flexible pipe (2). The latter is thus called non-smooth passage (“rough bore” in English). When the flexible pipe (2) is in service, the back-up (80) tends to disturb the flow of petroleum and / or gas fluid, in particular by creating pressure differentials. We then observe vibrational phenomena, or even, when a resonance is reached, phenomena of pulsation induced by the circulation of the fluid (called "flow induced pulsation" in English). These phenomena tend to accelerate the fatigue of related equipment and more particularly of the connection means (welding, flange, etc.).
    In order to reduce or even overcome these vibrational phenomena, the additional profile (8b) is arranged within the gap (80). Figure 2 shows for example the additional profile (8b) having a T-shaped section. More particularly, the section of the additional profile (8b) defines a central branch extending radially within the gap (80) and two free ends extending along the main profile (8a).
    In addition, a groove (not shown) can be provided on the internal and / or external surface of the additional profile (8b). The groove extends for example from the gap (80) formed by the main profile (8a) to the free end of the additional profile (8b). This groove facilitates the flow of petroleum and / or gas fluid between the gap (80) and the internal passage of the flexible pipe (2). Reference may in particular be made to patent application WO2015121424 in which such a groove is for example described.
    Figure 3 shows a second embodiment of the reinforcement structure (8). This second example can be taken in combination with the first embodiment of the reinforcement structure (8), the flexible pipe (2) then comprises two reinforcement structures (8) or as an alternative to the first embodiment, the flexible pipe ( 2) then comprises a reinforcing structure (8) according to the second example. Such a flexible pipe (2) is then said to have a smooth passage (“smooth bore” in English).
    According to this second example, the reinforcement structure (8) is arranged around the internal sealing sheath (3) and more particularly between the internal sealing sheath (3) and the tensile armor ply (5). The flexible pipe (2) is subjected to an internal pressure related to the circulation of the oil and / or gas fluid which can reach 200 bar or even more which can lead to the bursting of the flexible pipe (2). In order to limit or even overcome these risks of bursting of the flexible pipe (2), the reinforcing structure (8) is arranged around the internal sealing sheath (3).
    According to this second embodiment and with reference to Figure 3, the main section (8a) has a cross section of complex geometry formed for example of three main parts. The first part is in the form of a trapezoidal box from which the second part of the main profile (8a) extends and forms an arc of a circle whose apex is oriented towards the outside of the flexible pipe (2) . The third part forms a support surface of constant cross section on which the first part of an adjacent turn is wound and the end of which extends radially within the arc of said adjacent turn. This forms the stapling of the main profile (8a).
    The internal space of the arc formed by the second part of the main profile (8a) forms the gap (80) which opens radially onto the internal sealing sheath (3). Under the effect of internal pressure, the internal sealing sheath (3) can creep within the gap (80) causing risks of damage to the internal sealing sheath (3). The gap (80) is therefore partially or even filled in by the additional profile (8b).
    More particularly, the section of the additional profile (8b) defines a central branch extending radially within the gap (80) and two free ends extending respectively along a part of the third part of a turn of the profile main (8a) and part of the third part of an adjacent turn of the main profile (8a). More particularly, the central branch of the additional profile (8b) coexists within the gap (80) with the end of the third part of the main profile (8a).
    In a particular embodiment, the reinforcement structure (8) may include a mechanical reinforcement inserted into the turns of the main profile (8a) in order to improve the resistance to the radial forces exerted on the flexible pipe (2). Indeed, such mechanical reinforcement limits the deformation of the turns of the main profile (8a) under the effect of pressure.
    The manufacture of such a reinforcing structure (8) is carried out in several stages by an installation (1) according to the invention shown for example in Figures 4 and 5. The main profile (8a) and the additional profile (8b) are respectively profiled from a main strip (81a) and an additional strip (81b) respectively within a first profiling train (11) and a second profiling train (12) arranged on the same installation tray (10) (1). Winding means then make it possible to wind the main section (8a) and the additional section (8b) in order to form a tubular structure forming the reinforcement structure (8).
    The various elements of the installation (1) can be arranged on the plate (10), and in particular the first profiling train (11) and the second profiling train (12). Compared to installations for which these elements are arranged outside the plate (10) on the production sites, the plate (10) makes it possible to bring together the different elements of the installation (1) and thus to reduce their bulk. on said production sites.
    The length of the reinforcement structure (8) can be of the order of several tens of meters to several hundred meters. In addition, the flexible pipe (2) equipped with the reinforcing structure (8) is generally intended to be wound on storage coils after its manufacture. In order to allow this storage, the flexible pipe (2) equipped with the reinforcing structure (8) is generally locked in rotation about its longitudinal axis. Thus, to manufacture such lengths of reinforcement structure (8) continuously, the plate (10) is advantageously movable in rotation. The speed of rotation of the plate (10) is generally between a few rpm such as 5 rpm or 10 rpm and 60 rpm. In addition, preferably, the installation also includes a means for driving the plate in rotation, for example an electric motor. As regards the geometry of the plate (10), this can be of any shape suitable for the present invention, for example polygonal or circular. Regarding inertia, a plate (10) of substantially circular shape will still be preferred. Thus, as shown in Figures 4 and 5, the plate (10) is for example circular with center A and is for example made of steel.
    Furthermore, the installation (1) according to the invention may comprise a main reel (25a) of the main strip (81a) and a secondary reel (25b) of the additional strip (81b). The main reel (25a) makes it possible to deliver the main strip (81a) to the first profiling train (11) arranged on the plate (10) downstream of said main reel (25a). For simplification, only the main reel (25a) in connection with the main strip (81a) will be detailed in the following description. However, this applies to the secondary reel (25b) in connection with the additional strip (81b).
    The main reel (25a) can be arranged upstream of the tray (10), or directly on the tray (10) and more particularly on the front face of the tray (10) as shown for example in Figures 4 and 5. The reel main (25a) is notably mounted free in rotation on a shaft fixed on the plate (10). The unwinding of the main strip (81a) is braked by a friction element which can for example be a shoe arranged on the shaft and in contact with the main reel (25a) or arranged on the main reel (25a) and in contact with the 'tree. The main reel (25a) can for example be composed of a substantially circular body around which the main strip (81a) can be wound.
    Between the main reel (25a) and the first profiling train (11), the main strip (81a) can define a curved line. By curved line, it is understood that at least three consecutive points passing through said line are not aligned along a straight line. The installation (1) can then include guide members (26) arranged on the plate (10) along the main strip (81a), between the main reel (25a) and the first profiling train (11) as in particular shown in Figure 5. The guide members (26) may be, for example, rollers or any other element for guiding the main strip (81a) to the first profiling train (11). The guide members (26) may for example be two, three, four or even more depending on the distance and the curvature of the main strip (81a). The main strip (81a) is thus guided towards the first profiling train (11) in which it is profiled in a section as previously defined.
    The first profiling train (11) comprises at least one main profiling head (13) configured to receive the main strip (81a). The main profiling head (13) is formed of a pair of lower and upper main rollers (13a, 13b) capable of bending the main strip (81a). The circumference of the lower and upper main rollers (13a, 13b) defines a series of vertices and hollows making it possible to form a relief along which the main strip (81a) is profiled. The average diameter of the main rollers (13a, 13b) is for example between 40 mm and 200 mm. This average diameter can vary depending on the main profiling heads (13). The mean diameter of a roller is understood to mean the average of the values taken between the vertices and hollows of said roller.
    More particularly, the pair of lower and upper main rollers (13a, 13b) forms a first passage (15) into which the main strip (81a) is inserted. During the passage of the main strip (81a) within the first passage (15), the pair of lower and upper main rollers (13a, 13b) folds the main strip (81a) according to the relief formed by the pair of lower main rollers and higher (13a, 13b). Folding is generally carried out gradually. Indeed, as shown by way of example in FIGS. 4 and 5, the first profiling train (11) can comprise a plurality of main profiling heads (13) arranged in series. The number of profiling heads is generally chosen according to the complexity of the profile according to which the main strip (81a) is intended to be profiled and its thickness before and after profiling. For example, the first profiling train (11) can comprise two, three, four, five or six main profiling heads (13) or even more, each of the heads comprising a pair of lower and upper main rollers (13a, 13b) defining a relief in which the main strip (81a) is successively folded until the section of the main profile (8a) defined above is obtained. In the context of the present invention, the first profiling train (11) generally comprises between six to ten main profiling heads (13).
    As shown in detail in Figure 6, the lower and upper main rollers (13a, 13b) are respectively mounted on a lower (17a) and upper (17b) shaft. The latter are preferably removably mounted on a frame integral with the plate (10). The lower (17a) and upper (17b) shafts are thus more easily interchangeable, which facilitates maintenance of the installation (1) in the event of wear, for example. During the passage of the main strip (81a) within the first passage (15), radial forces are exerted on the lower (17a) and upper (17b) shafts which tend to separate them from one another. Thus, in order to maintain a constant distance between the lower (17a) and upper (17b) shafts during the passage of the main strip (81a), lower (18a) and upper (18b) glasses are respectively arranged on the ends of the shafts. lower (17a) and upper (17b) opposite the ends fixed to the frame. The lower (18a) and upper (18b) glasses are for example mounted on a bearing and connected to each other by bolts, the tightening level of which makes it possible to adjust the distance between said lower (18a) and upper (18b) glasses. In addition, the lower (17a) and upper (17b) shafts comprise means for locking in translation (21) the lower and upper main rollers (13a,
    13b). For example, a washer and nut assembly (21a, 21b) is screwed onto a threaded end of the lower (17a) and upper (17b) shafts. Opposite the threaded end, the lower (17a) and upper (17b) shafts may have a shoulder (21c) on which the lower and upper main rollers (13a, 13b) come into abutment.
    In addition, and as will be seen in more detail in the following description, the lower shaft (17a) and / or the upper shaft (17b) and hence, the lower and / or upper main roller (13a, 13b ) one or more main profiling heads (13) is rotated. The lower or upper main roller (s) (13a, 13b) which may not be driven are mounted to rotate freely. Thus, and with reference to FIG. 6, the lower and / or upper main roller (13a, 13b) driven in rotation generally comprises a rotation stop (19) on the lower (17a) and / or upper (17b) shaft. . For example, a groove can be provided on the lower (17a) and / or upper (17b) and on the lower and / or upper main roller (13a, 13b) driven in rotation. In this groove, can be accommodated a key intended to respectively block in rotation on the lower shaft (17a) and / or upper (17b) the lower main roller and / or upper (13a, 13b). According to the invention, certain lower and / or upper main rollers (13a, 13b) are possibly not driven (not shown). The latter are generally mounted on bearings, which can be cylindrical bearings of the sintered or self-lubricating type or bearings of the ball or needle bearing type or any other type of bearings well known to those skilled in the art.
    Thus, according to the invention, the installation (1) comprises a drive device (not shown) of the main profiling head (13). More particularly, the drive device comprises a motor intended to drive in rotation at least one lower shaft (17a) and / or upper (17b) relative to the plate (10) and hence, at least one lower main roller and / or higher (13a, 13b).
    One or more or all of the main profiling heads (13) can be coupled to the drive device. The drive device may include one or a plurality of motors intended to drive a plurality of lower shafts (17a) and / or upper shafts (17b). The lower (17a) and / or upper (17b) shafts, and hence the lower and / or upper main rollers (13a, 13b) can be driven with a similar or variable speed of rotation.
    The engine is generally electric. The electric motor can be of the asynchronous type connected to a speed variator making it possible to regulate the speed of rotation. The motor can moreover be a hydraulic, pneumatic motor or any other actuator well known to those skilled in the art.
    Also, the training device may include a movement transmission mechanism. The latter comprises for example a belt assembly or a simple or planetary gear train in which the diameter of the toothed wheels is chosen as a function of the speed of rotation to be transmitted to the lower (17a) and / or upper (17b) shaft. ). In another exemplary embodiment, the movement transmission mechanism may include a transmission shaft connected to a universal joint. The transmission mechanism is by no means limited to these particular examples and can be composed of other systems well known to those skilled in the art.
    Thus, according to the invention, the lower and / or upper main rollers (13a, 13b) driven by the drive device drive the main strip (81a) within the first passage (15) and fold it. The main strip (81a) is then generally in traction upstream of the first profiling train (11) and downstream, the main profile (8a) is pushed.
    Furthermore, with regard to the second profiling train (12), the latter comprises at least one additional profiling head (14) configured to receive the additional strip (81b). The additional profiling head (14) comprises a pair of upper and lower additional rollers (14a, 14b) capable of bending the additional strip (81b). The pair of upper and lower additional rollers (14a, 14b) forms a second passage (16) into which the additional strip (81b) is inserted. Reference will be made to the description of the first profiling train (11) with regard to the composition, arrangement and characteristics of the additional profiling head (14) and of the additional upper and lower rollers (14a, 14b). Only the differences are detailed below.
    The additional strip (81b) generally has a thickness (e2) less than or equal to the thickness (e1) of the main strip (81a). For example, the main strip (81a) has a thickness (e1) of between 1 mm and 6 mm and the additional strip (81b) has a thickness (2) of between 0.5 mm and 5 mm. Also, generally, the section of the additional profile (8b) is less complex than the section of the main profile (8a). Thus, the second profiling train (12) generally comprises fewer additional profiling heads (14) than the first profiling train (11).
    In addition, the pair of lower and upper additional rollers (14a, 14b) is able to fold the additional strip (81b) into an S or T-shaped section. The pair or pairs of additional lower and upper rollers (14a, 14b) of said or all of said additional profiling heads (14) are mounted to rotate freely relative to the plate (10). When the second profiling train (12) comprises several additional profiling heads (14), then, according to the invention, it is understood that all of the pairs of additional rollers (14a, 14b) of all the heads of additional profiling (14) are mounted to rotate freely relative to the plate (10). Like the lower and upper main rollers (13a, 13b) not driven in rotation, the additional rollers (14a, 14b) are mounted on bearings (20) as described above.
    Thus, according to the invention, the additional strip (81b) is driven within the second passage (16) mainly by friction between the main profile (8a) and the additional profile (8b) downstream of the first profiling train (11) and the second profiling train (12). This operation is all the more facilitated since the thickness of the additional profile (8b) is less than the thickness of the main profile (8a). Thus, the additional profile (8b) is in traction downstream of the first and second profiling train (11, 12). This also makes it possible to maintain the integrity of the main profile (8a) in particular insofar as the risks of buckling but also the risks of plastic deformation which can lead to cracks in the main profile (8a) at the outlet of the first profiling train (11 ) are reduced.
    As shown in Figure 4, the first and second profiling train (11, 12) are respectively arranged on the plate (10). To facilitate the assembly of the main profile (8a) with the additional profile (8b), the second profiling train (12) is advantageously located closer to the center (A) of the plate (10) than the first profiling train (11 ). Even more advantageously, the second profiling train (12) is arranged closer to the center (A) of the plate (10) than the first profiling train (11) with an angular offset, the latter being advantageously between 20 °. and 45 °. It being understood that the angular offset represents the angle formed by the intersection of the straight lines passing respectively through the first passage (15) and the second passage (16).
    According to another example (not shown), the first and the second profiling train (11,12) are arranged in parallel. The axis of the lower (17a) and upper (17b) shafts on which the lower and upper main rollers (13a, 13b) are respectively mounted and the lower and upper additional rollers (14a, 14b) are parallel and removably mounted on a frame common integral with the plate (10).
    According to yet another embodiment shown in Figures 5 and 7 in which the first and second profiling train (11, 12) are also arranged in parallel, at least one of the additional lower or upper rollers (14a, 14b) is respectively arranged in the axis of at least one of the lower or upper main rollers (13a, 13b). Thus, the lower or upper main rollers (13a, 13b) are respectively arranged on the same lower (17a) or upper (17b) shaft as the lower or upper additional rollers (14a, 14b). As described above, the lower (17a) and upper (17b) shafts have means for blocking in translation (21) the lower and upper main rollers (13a, 13b) and additional lower and upper rollers (14a, 14b). For example, a washer and nut assembly (21a, 21b) is arranged on a threaded end of the lower (17a) and upper (17b) shafts. Opposite the threaded end, the lower (17a) and upper (17b) shafts include a shoulder (21c) on which the lower and upper main rollers (13a, 13b) or the lower and upper additional rollers (14a, 14b) can come into abutment. Also, a spacer (21 d) can be arranged respectively between the lower main roller (13a) and the lower additional roller (14a). A spacer (21d) is also arranged between the upper main roller (13b) and the upper additional roller (14b). Also, the lower (18a) and upper (18b) goggles are respectively arranged on the threaded end of the lower (17a) and upper (17b) shafts opposite the ends fixed to the frame. This particular embodiment simplifies the mounting of the second profiling train (12) in that the additional lower and upper rollers (14a, 14b) can be directly arranged on the lower (17a) and upper (17b) shafts of the first profiling train (11).
    Furthermore, downstream of the first and second profiling train (11, 12), the main profile (8a) and the additional profile (8b) are bent and wound in the vicinity of the center A of the plate (10) according to a flexible tubular structure forming the reinforcing structure (8). Thus, the installation (1) comprises a means for winding the main profile (8a) and the additional profile (8b).
    The winding means advantageously comprises a support member (23) intended to support the main profile (8a) and the additional profile (8b). Indeed, the winding and bending of the main profile (8a) and the additional profile (8b) to form a tubular structure causes significant radial forces which can crush the reinforcement structure (8) during formation. The support member (23) thus forms a mechanical support structure on which large radial forces can be exerted without damaging the reinforcement structure (8) being formed during the bending and winding of the main profile. (8a) and the additional profile (8b). The support member (23) is formed of a cylindrical structure extending coaxially projecting from the plate (10).
    According to a first example, the support member (23) comprises for example a mandrel. This example is particularly advantageous when the reinforcing structure (8) constitutes the innermost layer of the flexible pipe (2), such as the carcass. The mandrel is generally made of steel. The mandrel has a substantially cylindrical section with a conical end and has a diameter taken along the largest base, for example between 25 mm and 635 mm. Preferably, a drive device makes it possible to rotate the mandrel around the axis (A-A ’). The speed of rotation of the mandrel is preferably at least forty times lower than the speed of rotation of the plate (10). The rotation of the mandrel is generally opposite with respect to the plate (10), which tends to locally increase the diameter of the reinforcement structure (8) and to allow its release from the mandrel without jamming. Also, the rotational speeds of the mandrel, the plate (10) and the lower and upper main rollers (13a, 13b) can be such that the main section (8a) is in traction downstream of the first and second profiling train ( 11, 12). Thus, the invention also applies to a particular embodiment of the invention in which the main profile (8a) profile is subjected to a tensile stress downstream of the first profiling train (11).
    A mandrel lubricating member for supplying a lubricating fluid to the external surface of the mandrel in contact with the reinforcing structure (8) may also be provided in order to reduce the coefficient of friction between the external surface of the mandrel and the additional profile. (8b). The lubrication member is for example composed of a plurality of injection orifices arranged in the mandrel and distributed over the length of the mandrel allowing the passage of the lubrication fluid over the external surface of the mandrel. The lubrication fluid is for example a hydrocarbon fluid. The coefficient of friction between the external surface of the mandrel and the reinforcing structure is for example less than 0.1 after the lubrication of the external surface of the mandrel. In addition to or as an alternative to the lubrication member, the mandrel may also include a surface coating which also makes it possible to reduce the coefficient of friction between the external surface of the mandrel and the additional profile (8b). For example, the surface coating is formed by a layer of chromium.
    According to a second particularly advantageous example, in particular when the reinforcing structure (8) is arranged around the internal sealing sheath (3) such as a pressure vault, the support member (23) is formed by the internal sealing sheath (3) and the carcass of the flexible pipe (2). Indeed, the carcass of the flexible pipe (2) has a resistance to radial forces which makes it possible to dispense with an additional support structure for the manufacture of the pressure vault. According to this example, the support member (23) also comprises a plurality of rollers arranged around the center of the plate (10) forming a plurality of support points on which the main profile (8a) and the additional profile (8b ) are bent to form the reinforcement structure (8). Generally, at least two diametrically opposite rollers are arranged around the center of the plate (10).
    Furthermore, around the support member (23), the winding means advantageously comprises a plurality of cladding members (24) making it possible to facilitate the assembly of the main profile (8a) with the additional profile (8b ) by holding them and bending on the support member (23). In a particular embodiment of the invention, the winding means comprises four plating members (23) distributed around the support member (23). The four cladding members (23) can for example be regularly distributed around the support member (23) with an angular interval between 50 ° and 70 ° and more particularly, with an angular interval between 60 ° and 70 °. The cladding members (24) are for example rollers capable of pressing and possibly bending the main profile (8a) and the additional profile (8b) assembled. Advantageously, the plating members (24) are mounted to rotate freely.
    Guide members (26) of the type described above can also be arranged between the first profiling train (11) and the support member (23) and / or the second profiling train (12) and the support member (23) in order to bring the main profile (8a) and / or the additional profile (8b) tangentially to the mandrel.
    The installation (1) can also include one or more additional profiling trains (not shown) making it possible to profile one or more additional strips.
    Furthermore, the installation (1) can be integrated into a system (100) for manufacturing the flexible pipe (2). With reference to FIG. 8, the system (100) comprises, in addition to the installation (1) previously described, a device (101) for manufacturing the internal sealing sheath (3) arranged upstream or downstream of said installation ( 1).
    The device (101) for manufacturing the internal sealing sheath (3) is for example an extrusion line arranged downstream of the installation (1) when the reinforcement structure (8) is arranged inside the internal sealing sheath (3) such as a carcass or upstream of the installation (1) when the reinforcing structure (8) is arranged around the internal sealing sheath (3) such as a vault pressure. The extrusion line includes an extruder making it possible to form the internal sealing sheath (3), a cooling member allowing the polymerization of the internal sealing sheath (3) and a traction member allowing the translation of the flexible pipe. (2) to a possible next device. As an example, reference may be made to patent application WO2009141538 in which an extruder adapted to the present invention is described.
    In addition, downstream of the installation (1) and the extrusion line, the system (100) may include a device (102) for manufacturing the tensile armor ply (5).
    The device (102) for manufacturing the tensile armor ply (5) comprises several coils of tensile armor wires supplying, for example, two traction heads, each forming the layers of tensile armor (6, 7) . Reference may in particular be made to patent application WO2010012897 in which such a device (102) is for example described.
    Advantageously, the system (100) can also comprise a device (103) for manufacturing the external protective sheath (9) arranged downstream of the device (102) for manufacturing the tensile armor ply (5). The device (103) for manufacturing the external protective sheath (9) is for example an extruder, similar to the device (101) for manufacturing the internal sealing sheath (3).
    The system (100) may also include a device (104) for storing the flexible pipe (2). For example, the device (104) for storing the flexible pipe (2) is formed of a coil on which the flexible pipe (2) can be wound.
    The system (100) may comprise, in addition to the aforementioned devices, additional devices for manufacturing and / or laying intermediate layers such as anti-wear, thermal insulation or mechanical reinforcement strips, or any other type of layers that can compose the flexible pipe (2). Also, the system (100) may include an additional device for laying electrical and / or optical cables and / or tubes in an SZ configuration of the type described in patent application WO2014 / 091100 or in a helical configuration .
    A method for implementing the installation (1) for manufacturing the reinforcement structure (8) of the flexible pipe (2) will now be described.
    In a possible stage of preparation of the first and second profiling train (11, 12), the main rollers (13a, 13b) and the additional rollers (14a, 14b) are selected, making it possible to fold the main strip (81a) and the additional strip (81b) according to the sections as defined above. Said main (13a, 13b) and additional (14a, 14b) rollers are then mounted on the respective lower (17a) and upper (17b) shafts. When the main (13a, 13b) and additional (14a, 14b) rollers share the same shafts (17a, 17b), advantageously, the additional rollers (14a, 14b) are mounted on the shafts (17a, 17b) after mounting the rollers main (13a, 13b). The additional rollers (14a, 14b) are advantageously further from the plate (10) than the main rollers (13a, 13b), which facilitates the profiling of the main strip (81a) and the additional strip (81b).
    In a step (a), the first profiling train (11) of the main strip (81a) is arranged on the plate (10). The first profiling train (11) comprises the main profiling head (13) composed of the main rollers (13a, 13b) making it possible to fold the main strip (81a). Furthermore, the drive device is advantageously coupled to the main profiling head (13) in order to drive the lower (17a) and / or upper (17b) shafts and hence the lower and / or upper main rollers (13a). , 13b) in rotation during a next step (c).
    In a second step (b), the second profiling train (12) of the additional strip (81b) comprising the additional profiling head (14) is arranged on the plate (10). The additional rollers (14a, 14b) making it possible to fold the additional strip (81b) and forming the additional profiling head (14) being mounted free to rotate.
    In the embodiment according to which at least one of the lower or upper additional rollers (14a, 14b) is respectively arranged in the axis of at least one of the lower or upper main rollers (13a, 13b), then it is it is understood that steps (a) and (b) can be carried out simultaneously. Indeed, as soon as the lower and upper additional rollers (14a, 14b) share the same lower and upper shaft (17a, 17b) respectively as the lower and upper main rollers (13a, 13b), then the latter can be preinstalled on said shafts, the establishment of the first profiling train (11) thus implying the establishment of the second profiling train (12).
    Advantageously, a step (b ’) for feeding the main strip (81a) and additional strip (81b) is carried out. During this step, at least one main strip reel (81a) and at least one additional strip reel (81b) are respectively loaded on the main reel (25a) and the secondary reel (25b). The main strip (81a) and the additional strip (81b) are then respectively inserted within the first passage (15) formed by the main rollers (13a, 13b) and the second passage (16) formed by the additional rollers (14a, 14b).
    Then in a third step (c), the main profiling head (13) is driven. In fact, during step (c), the drive device is put into service by means of a control console for example, causing the lower (17a) and / or upper (17b) shaft to rotate and hence, the lower and / or upper main rollers (13a, 13b). The driving in rotation of said lower and / or upper main rollers (13a, 13b) drives the main strip (81a) through the first passage (15). As regards the additional strip (81b), the driving of the main strip (81a) and the possible rotation of the plate (10) allows, by friction of the main (8a) and additional (8b) sections downstream of the first train of profiling (11) and the second profiling train (12), pulling the additional strip (81b) through the second passage (16). A profiling step (d) is then carried out during the respective passage of the main (81a) and additional (81b) strips through the first passage (15) and the second passage (16), where they are respectively profiled by the main rollers lower and upper (13a, 13b) and the additional lower and upper rollers (14a, 14b).
    Then, during a step (e), downstream of the first profiling train (11) and the second profiling train (12), the main profile (8a) and the additional profile (8b) are wound around a winding means in a tubular structure. More particularly, the main profile (8a) and the additional profile (8b) are wound around the support member (23) in a short pitch, between 75 ° and 90 °. The carrying out of this folding step (e) is advantageously facilitated by the plating members (24) arranged around the support member (23).
