Description

La présente invention a trait au domaine du forage et de l'exploitation pétrolière de gisement en mer très profonde. Elle concerne tronçon de colonne montante.The present invention relates to the field of drilling and oil field exploitation in very deep sea. It concerns riser section.

Une colonne montante de forage est constituée par un ensemble d'éléments tubulaires, assemblés par des connecteurs. Les éléments tubulaires sont généralement constitués d'un tube principal muni de connecteur à chaque extrémité. Le tube principal est pourvu de conduites auxiliaires couramment nommée "kill line", "choke line", "booster line" et "hydraulic line" qui permettent la circulation de fluide technique. Les éléments tubulaires sont assemblés sur le lieu de forage, à partir d'un support flottant. La colonne descend dans la tranche d'eau au fur et à mesure de l'assemblage des éléments tubulaires, jusqu'à atteindre la tête de puits située sur le fond marin.A riser is constituted by a set of tubular elements, assembled by connectors. Tubular elements generally consist of a main tube provided with connector at each end. The main tube is provided with auxiliary pipes commonly called "kill line", "choke line", "booster line" and "hydraulic line" which allow the circulation of technical fluid. The tubular elements are assembled on the drilling site, from a floating support. The column descends into the water portion as the assembly of the tubular elements, until reaching the wellhead located on the seabed.

Dans l'optique de forer à des profondeurs d'eau pouvant atteindre 3500 m ou plus, le poids de la colonne montante devient très pénalisant. Ce phénomène est aggravé par le fait que, pour une même pression maximale de service, la longueur de la colonne impose un diamètre intérieur des conduites auxiliaires plus grand compte tenu de la nécessité de limiter les pertes de charge.In order to drill at water depths up to 3500 m or more, the weight of the riser becomes very penalizing. This phenomenon is aggravated by the fact that, for the same maximum operating pressure, the length of the column imposes an inner diameter of the auxiliary lines larger given the need to limit the pressure losses.

Par ailleurs, la nécessité de diminuer le temps d'assemblage des colonnes montantes est d'autant plus critique que la profondeur d'eau, et donc la longueur de la colonne, sont importantes.Furthermore, the need to reduce the assembly time of the risers is all the more critical as the water depth, and therefore the length of the column, are important.

Les documents FR 2 891 577 , FR 2 891 578 et FR 2 891 579 décrivent différentes solutions proposant notamment de faire participer les conduites auxiliaires, conjointement avec le tube principal, à la reprise des efforts longitudinaux appliqués à la colonne montante.The documents FR 2 891 577 , FR 2 891 578 and FR 2 891 579 describe various solutions including proposing to involve the auxiliary pipes, together with the main tube, the recovery of the longitudinal forces applied to the riser.

Le document FR 2 799 789 , qui est considéré comme l'état de la technique le plus proche, divulgue un tronçon de colonne montante pour les opérations de forage de puits en mer, comportant un élément de tube principal prolongé par un élément connecteur mâle et par un élément connecteur femelle comportant une première série de tenons disposée sur la surface extérieure de l'élément connecteur femelle, dans lequel au moins un élément de tube auxiliaire est solidaire de l'élément connecteur mâle et de l'élément connecteur femelle de manière à ce que le tube principal et l'élément de tube auxiliaire transmettent conjointement des efforts de tension entre l'élément connecteur mâle et l'élément connecteur femelle, et dans lequel une bague de verrouillage est montée sur l'élément connecteur mâle, adaptée a coopérer avec la première série de tenons de l' élément connecteur femelle.The document FR 2,799,789 , which is considered to be the closest state of the art, discloses a riser section for offshore well drilling operations, comprising a main tube member extended by a male connector member and a female connector member comprising a first set of pins disposed on the outer surface of the female connector member, wherein at least one auxiliary tube member is integral with the male connector member and the female connector member so that the main tube and the auxiliary tube element jointly transmit tension forces between the male connector element and the female connector element, and wherein a locking ring is mounted on the male connector element, adapted to cooperate with the first series of tenons of the female connector element.

Le document FR 2 557 194 décrit un système de verrouillage à baïonnette avec une bague de verrouillage positionnée entre l'élément mâle et l'élément femelle du connecteur.The document FR 2 557 194 discloses a bayonet locking system with a locking ring positioned between the male member and the female member of the connector.

Le document US 6,932,355 propose un système de connexion de tubes dans lequel le connecteur mâle coopère directement avec l'élément connecteur femelle via le système de butées et l'élément de verrouillage est situé à l'extérieur des éléments mâle et femelle du connecteur.The document US 6,932,355 proposes a tube connection system in which the male connector cooperates directly with the female connector element via the stop system and the locking element is located outside the male and female elements of the connector.

La figure 1 schématise une colonne montante 1 installée en mer. La colonne montante 1 prolonge le puits P et s'étend depuis la tête de puits 2 jusqu'au support flottant 3, par exemple une plateforme ou un bateau. La tête de puits 2 est munie d'obturateur couramment nommé "B.O.P." ou "Blow Out Preventer". La colonne montante est constituée par l'assemblage de plusieurs tronçons 4 assemblés bout à bout par les connecteurs 5. Chaque tronçon est composé d'un élément de tube principal 6 muni d'au moins un élément de conduite périphérique 7. Les conduites auxiliaires dénommées "kill line" ou "choke line" sont utilisées pour assurer la sécurité du puits pendant le déroulement des procédures de contrôle des venues de fluides sous pression dans le puits.

The riser 1 extends the well P and extends from the wellhead 2 to the floating support 3, for example a platform or a boat. The wellhead 2 is provided with shutter commonly called "BOP" or "Blow Out Preventer". The riser is constituted by the assembly of several sections 4 assembled end to end by the connectors 5. Each section is composed of a main tube element 6 provided with at least one peripheral pipe element 7. The auxiliary pipes called "kill line" or "choke line" are used to ensure the safety of the well during the course of the procedures for controlling the inflow of fluids under pressure in the well. The so-called "booster line" is used to inject sludge into the well. The pipe called "hydraulic line" allows to control the shutter of the wellhead.

La figure 2 représente schématiquement un tronçon 4 de la colonne montante. Le tronçon 4 comporte un élément de tube principal 6 dont l'axe AA' constitue l'axe de la colonne montante. Les tubes 7 constituent des lignes ou conduites auxiliaires disposées parallèlement à l'axe AA'. Les éléments 7 ont des longueurs sensiblement égales à la longueur de l'élément de tube principal 6, en général compris enture 10 et 30 mètres. Il y a au moins une ligne 7 disposée à la périphérie du tube principale. Sur la figure 2, deux lignes 7 sont schématisées.The figure 2 schematically represents a section 4 of the riser. The section 4 comprises a main tube element 6 whose axis AA 'constitutes the axis of the riser. The tubes 7 constitute lines or auxiliary lines arranged parallel to the axis AA '. The elements 7 have lengths substantially equal to the length of the main tube element 6, generally included between 10 and 30 meters. There is at least one line 7 disposed at the periphery of the main tube. On the figure 2 two lines 7 are schematized.

Un connecteur 5 représenté sur la figure 1 est constitué de deux éléments désignés, en référence à la figure 2, par l'élément de connexion femelle 9 et l'élément de connexion mâle 10. Les éléments 9 et 10 sont montés aux extrémités de l'élément de tube principal 6. L'élément femelle 9 du connecteur est solidaire du tube 6, par exemple au moyen du soudage 11, d'un vissage, d'un sertissage ou d'une liaison par coincement. L'élément mâle 10 du connecteur est solidaire du tube 6, par exemple au moyen du soudage 12, d'un vissage, d'un sertissage ou d'une liaison par coincement. L'assemblage de l'élément de connexion mâle 10 avec l'élément de connexion femelle 9 forme le connecteur 5 qui transmet des efforts d'un tronçon de colonne montante au tronçon suivant, notamment les efforts longitudinaux auxquels est soumise la colonne montante.A connector 5 shown on the figure 1 consists of two designated elements, with reference to the figure 2 , by the female connection element 9 and the male connection element 10. The elements 9 and 10 are mounted at the ends of the main tube element 6. The female element 9 of the connector is secured to the tube 6, by example by means of welding 11, screwing, crimping or binding by wedging. The male element 10 of the connector is secured to the tube 6, for example by means of the welding 12, screwing, crimping or binding by binding. The assembly of the male connection element 10 with the female connection element 9 forms the connector 5 which transmits forces of a rising column section to the next section, including the longitudinal forces to which the riser is subjected.

Le connecteur 5 peut être conçu et dimensionné pour satisfaire les spécifications mentionnées par les normes API 16 R et API 2RD éditées par l'American Petroleum Institute.The connector 5 can be designed and dimensioned to meet the specifications mentioned by the API 16 R and API 2RD standards published by the American Petroleum Institute.

La figure 3 représente un élément tubulaire mâle 10 qui est emboîté dans l'élément tubulaire femelle 9. Une portion de l'élément tubulaire mâle 10 pénètre dans l'élément tubulaire femelle 9. Cet emboîtement est limité par la butée axiale 21 (l'extrémité de l'élément mâle 10 vient en butée contre l'épaulement axiale 21 pratiqué sur la surface intérieure de l'élément femelle 9) ou par la butée axiale 20 (l'épaulement axial 20 pratiqué sur la surface extérieure de l'élément mâle 10 vient en butée contre l'épaulement axial 20 pratiqué sur la surface intérieure de l'élément femelle 9).The figure 3 represents a male tubular element 10 which is fitted into the female tubular element 9. A portion of the male tubular element 10 penetrates into the female tubular element 9. This interlocking is limited by the axial abutment 21 (the end of the tubular element). male element 10 abuts against the axial shoulder 21 formed on the inner surface of the female element 9) or by the axial abutment 20 (the axial shoulder 20 formed on the outer surface of the male element 10 comes into abutment against the axial shoulder 20 formed on the inner surface of the female element 9).

Le connecteur 5 comporte une bague de verrouillage 22 qui est positionnée entre l'élément 9 et l'élément 10. Lorsque l'élément 10 est emboîté dans l'élément femelle 9, une partie de la bague 22 pénètre dans l'élément femelle 9 de manière à ce que les tenons de la bague 22 coopèrent avec les tenons de l'élément femelle 9. Le verrouillage et le déverrouillage du connecteur 5 sont réalisés par rotation de la bague 22 (verrouillage du type à baïonnette). La bague 22 est munie d'un moyen de manoeuvre, par exemple la barre de manoeuvre 8 qui peut être démontable. La barre de manoeuvre 8 permet de faire tourner la bague 22 dans son logement pratiqué dans l'élément 10, autour de l'axe AA'. Les efforts longitudinaux, c'est-à-dire qui sont dirigés selon l'axe AA', sont transmis d'un tronçon 4 au tronçon adjacent 4 par l'intermédiaire de la connexion de type baïonnette entre la bague 22 et l'élément femelle 9. Plus précisément, les efforts longitudinaux sont transmis des tenons de la bague 22 aux tenons de l'élément femelle 9.The connector 5 comprises a locking ring 22 which is positioned between the element 9 and the element 10. When the element 10 is fitted into the female element 9, part of the ring 22 enters the female element 9 so that the tenons of the ring 22 cooperate with the tenons of the female element 9. The locking and unlocking of the connector 5 are made by rotation of the ring 22 (locking type bayonet). The ring 22 is provided with an operating means, for example the maneuvering bar 8 which can be dismountable. The operating bar 8 rotates the ring 22 in its housing formed in the element 10, about the axis AA '. The longitudinal forces, that is to say which are directed along the axis AA ', are transmitted from a section 4 to the adjacent section 4 via the bayonet type connection between the ring 22 and the element 9. More precisely, the longitudinal forces are transmitted from the tenons of the ring 22 to the tenons of the female element 9.

La bague de verrouillage est montée mobile en rotation sur l'élément mâle10, tout en étant bloquée en translation, en particulier selon la direction de l'axe AA'. En référence à la figure 3, la bague 22 est montée sur la surface extérieure de l'élément 10. Elle est maintenue dans un logement défini et limité par les épaulements axiaux 23 et 24 pratiqués sur l'élément 10. Pour effectuer le montage de la bague de verrouillage 22 sur l'élément 10, on peut réaliser l'élément 10 en deux parties 10a et 10b. La bague 22 est montée sur la partie 10b jusqu'à être en butée contre l'épaulement axial 24 pratiqué sur la surface extérieure de la partie 10b. Puis on fixe solidairement la partie 10b dans la partie 10a de manière à ce que la bague soit en butée contre l'épaulement 23 de la partie 10b. Par exemple la partie 10b est vissée ou soudée dans la partie 10a. Alternativement les parties 10a et 10b de l'élément 10 peuvent former une seule pièce. Dans ce cas, la bague 22 est constituée de deux parties qui sont assemblées autour de la partie 10a de l'élément 10.The locking ring is rotatably mounted on the male member 10, while being locked in translation, in particular in the direction of the axis AA '. With reference to the figure 3 , the ring 22 is mounted on the outer surface of the element 10. It is held in a defined housing and limited by the axial shoulders 23 and 24 formed on the element 10. To mount the locking ring 22 on the element 10, one can achieve the element 10 in two parts 10a and 10b. The ring 22 is mounted on the portion 10b to abut against the axial shoulder 24 formed on the outer surface of the portion 10b. Then the part 10b is integrally fixed in the part 10a so that the ring abuts against the shoulder 23 of the part 10b. For example the part 10b is screwed or welded in the part 10a. Alternatively the parts 10a and 10b of the element 10 can form a single piece. In this case, the ring 22 consists of two parts which are assembled around the part 10a of the element 10.

En référence à la figure 3, l'élément femelle 9 et la bague 22 comportent respectivement deux couronnes de tenons ou ergots 9A et 9B, et 22A et 22B, permettant d'assurer le verrouillage axial du connecteur 5. Les tenons s'étendent préférentiellement selon des directions radiales. Sur la figure 4, l'élément femelle 9 comporte une première couronne 9A de quatre tenons 9A1, 9A2, 9A3 et 9A4 et une deuxième couronne 9B de quatre tenons 9B1, 9B2, 9B3 et 9B4. La bague 22 comporte également une première couronne 22A de quatre tenons 22A1, 22A2, 22A3 et 22A4 et une deuxième couronne 22B de quatre tenons 22B1, 22B2, 22B3 et 22B4.With reference to the figure 3 , the female element 9 and the ring 22 respectively comprise two stud rings or lugs 9A and 9B, and 22A and 22B, to ensure the axial locking of the connector 5. The tenons preferably extend in radial directions. On the figure 4 , the female element 9 comprises a first ring 9A of four studs 9A1, 9A2, 9A3 and 9A4 and a second ring 9B of four pins 9B1, 9B2, 9B3 and 9B4. The ring 22 also comprises a first ring 22A of four pins 22A1, 22A2, 22A3 and 22A4 and a second ring 22B of four pins 22B1, 22B2, 22B3 and 22B4.

Les tenons sont décalés angulairement d'une couronne à l'autre et inscrits dans des surfaces cylindriques de rayons différents. En référence à la figure 3, les première et deuxième couronnes de l'élément femelle 9 sont respectivement inscrites dans les surfaces cylindriques de rayon r et R. Les première et deuxième couronnes de la bague 22 sont respectivement inscrites dans les surfaces cylindriques de rayon r' et R'. Le rayon r est légèrement supérieur au rayon R' de manière à ce que les tenons 22B1 à 22B4 de la deuxième couronne de la bague 22 puissent coulisser et tourner librement à l'intérieur du cylindre formé par la surface intérieure des tenons 9A1 à 9A4 de la première couronne 9A de l'élément femelle 9.The tenons are angularly offset from one crown to the other and inscribed in cylindrical surfaces of different radii. With reference to the figure 3 , the first and second rings of the female element 9 are respectively inscribed in the cylindrical surfaces of radius r and R. The first and second rings of the ring 22 are respectively inscribed in the cylindrical surfaces of radius r 'and R'. The radius r is slightly greater than the radius R 'so that the tenons 22B1 to 22B4 of the second ring of the 22 ring can slide and rotate freely inside the cylinder formed by the inner surface of the pins 9A1 to 9A4 of the first ring 9A of the female element 9.

Les tenons 22A1, 22A2, 22A3 et 22A4 de la première couronne de la bague 22 coopèrent avec les tenons 9A1, 9A2, 9A3 et 9A4 de la première couronne de l'élément femelle 9 pour former un assemblage à baïonnette. Les tenons 22B1, 22B2, 22B3 et 22B4 de la deuxième couronne de la bague 22 coopèrent avec les tenons 9B1, 9B2, 9B3 et 9B4 de la deuxième couronne de l'élément femelle 9B.The tenons 22A1, 22A2, 22A3 and 22A4 of the first ring of the ring 22 cooperate with the pins 9A1, 9A2, 9A3 and 9A4 of the first ring of the female element 9 to form a bayonet assembly. The tenons 22B1, 22B2, 22B3 and 22B4 of the second ring of the ring 22 cooperate with the pins 9B1, 9B2, 9B3 and 9B4 of the second ring of the female element 9B.

Plus précisément lors de l'engagement de la bague 22 dans l'élément femelle 9, la bague 22 suit un mouvement de translation dans la direction de l'axe AA' selon les étapes successives :

  • la deuxième couronne 22B de la bague passe à l'intérieur de la couronne 9A de l'élément femelle, puis
  • les tenons 22B s'engagent entre les tenons 9B et simultanément les tenons 22A s'engagent entre les tenons 9A, puis
  • lorsque la bague 22 arrive en butée contre l'élément 9, les tenons 22A1, 22A2, 22A3 et 22A4 se logent dans la rainure 25 (schématisée sur la figure 4) pratiquée dans l'élément femelle 9 entre la première couronne 9A et la deuxième couronne 9B et les tenons 22B1, 22B2, 22B3 et 22B4 se logent dans la rainure 26 (schématisée sur la figure 4) pratiquée dans l'élément femelle 9 sous la deuxième couronne 9B.
More precisely, during the engagement of the ring 22 in the female element 9, the ring 22 follows a translation movement in the direction of the axis AA 'according to the successive steps:
  • the second ring 22B of the ring passes inside the ring 9A of the female element, then
  • the tenons 22B engage between the tenons 9B and simultaneously the tenons 22A engage between the tenons 9A, then
  • when the ring 22 comes into abutment against the element 9, the tenons 22A1, 22A2, 22A3 and 22A4 are housed in the groove 25 (shown schematically on the figure 4 ) made in the female element 9 between the first ring 9A and the second ring 9B and the pins 22B1, 22B2, 22B3 and 22B4 are housed in the groove 26 (shown schematically on the figure 4 ) practiced in the female element 9 under the second ring 9B.

Puis lorsque la bague 22 est en butée contre l'élément femelle 9, on fait pivoter la bague 22 de- manière à ce que les tenons de la bague soient positionnés face aux tenons de l'élément femelle. Les tenons de la couronne 22A sont positionnés face aux tenons de la couronne 9A et les tenons de la couronne 22B sont positionnés face aux tenons de la couronne 9B. Ainsi les tenons de la bague 22 sont en butées axiales par rapport aux tenons de l'élément femelle 9 et bloquent en translation l'élément 9 par rapport à l'élément 10.Then when the ring 22 is in abutment against the female element 9, the ring 22 is pivoted so that the tenons of the ring are positioned facing the tenons of the female element. The tenons of the ring 22A are positioned facing the tenons of the ring 9A and the tenons of the ring 22B are positioned facing the tenons of the ring 9B. Thus the tenons of the ring 22 are in axial abutments with respect to the tenons of the female element 9 and block in translation the element 9 with respect to the element 10.

Chacun des deux systèmes d'assemblage à baïonnette peut permettre d'assurer entre les tenons de l'élément femelle 9 et les tenons de la bague 22 un contact sur une plage angulaire totale qui peut atteindre 175°. De préférence, les deux systèmes d'assemblage étant angulairement décalés autour de l'axe du connecteur, le connecteur selon l'invention permet de répartir les charges axiales sur environ 350° autour de l'axe.Each of the two bayonet assembly systems can ensure between the tenons of the female element 9 and the tenons of the ring 22 a contact over a total angular range that can reach 175 °. Preferably, the two assembly systems being angularly offset around the axis of the connector, the connector according to the invention allows to distribute the axial loads about 350 ° around the axis.

Alternativement, selon l'invention, la bague 22 et l'élément 9 peuvent ne comporter chacun qu'une seule couronne : les tenons de l'unique couronne de la bague 22 coopèrent avec les tenons de l'unique couronne de l'élément 9.Alternatively, according to the invention, the ring 22 and the element 9 may each comprise only one crown: the tenons of the single ring of the ring 22 cooperate with the tenons of the single ring of the element 9 .

Le nombre de tenons par couronne peut varier, notamment en fonction des diamètres du tube intérieur et des efforts à transmettre par le connecteur.The number of tenons per ring may vary, in particular depending on the diameters of the inner tube and the forces to be transmitted by the connector.

Un système de verrouillage permet de bloquer en rotation la bague 22.A locking system makes it possible to lock the ring 22 in rotation.

Selon l'invention, l'élément de conduite auxiliaire 7 est solidairement lié à chacune de ses extrémités au tube principal 6. En d'autres termes, le tronçon de colonne montante 1 comporte à chacune de ses extrémités des moyens de fixation 30 et 31, schématisés sur la figure 3, qui permettent de lier axialement un élément de conduite auxiliaire 7 au tube principal 6. Selon l'invention, les moyens 30 et 31 permettent de transmettre des efforts longitudinaux du tube principal 6 aux éléments 7. Ainsi, ces moyens de fixation 30 et 31 permettent de répartir les efforts de tension, s'appliquant sur chacun des tronçons de la colonne montante, entre le tube principal 6 et les éléments de conduite auxiliaire 7.According to the invention, the auxiliary pipe element 7 is integrally connected at each of its ends to the main pipe 6. In other words, the riser section 1 comprises at each of its ends fastening means 30 and 31. , schematized on the figure 3 , which make it possible to axially link an auxiliary pipe element 7 to the main pipe 6. According to the invention, the means 30 and 31 make it possible to transmit longitudinal forces of the main pipe 6 to the elements 7. Thus, these fastening means 30 and 31 allow to distribute the tensioning forces applying to each of the sections of the riser, between the main tube 6 and the auxiliary pipe elements 7.

Au niveau de l'extrémité du tronçon munie du moyen de connexion femelle 9, le tube principal 6 est prolongé par l'épaulement ou bride 13 comportant un passage cylindrique dans lequel l'élément de conduite auxiliaire 7 peut coulisser. L'élément auxiliaire 7 comporte une butée 35, par exemple un écrou ou un épaulement pour positionner axialement l'élément 7 par rapport à la bride 13. Lors du montage de l'élément 7 sur le tube principal 6, la butée 35 de l'élément 7 vient en appui sur la bride 13, par exemple contre l'épaulement axial pratiqué dans le passage 34 de sorte à former une liaison rigide.At the end of the section provided with the female connection means 9, the main tube 6 is extended by the shoulder or flange 13 having a cylindrical passage in which the auxiliary pipe element 7 can slide. The auxiliary element 7 comprises a stop 35, for example a nut or a shoulder for axially positioning the element 7 with respect to the flange 13. When mounting the element 7 on the main pipe 6, the stop 35 of the element 7 bears on the flange 13, for example against the axial shoulder formed in the passageway 34 so as to form a rigid connection.

Au niveau de l'extrémité du tronçon munie du moyen de connexion mâle 10, le tube principal 6 est prolongé par l'épaulement ou bride 14 comportant un passage cylindrique 32 dans lequel l'élément de conduite auxiliaire 7 peut coulisser. L'élément de conduite auxiliaire 7 comporte une butée 33, par exemple un écrou ou un épaulement, pour positionner axialement l'élément 7 par rapport à la bride 14. Lors du montage de l'élément 7 sur le tube principal 6, la butée de l'élément 7 vient en appui sur la bride 14, par exemple contre l'épaulement axial pratiqué dans le passage 32, de sorte à former une liaison rigide.At the end of the section provided with the male connection means 10, the main tube 6 is extended by the shoulder or flange 14 having a cylindrical passage 32 in which the auxiliary line element 7 can slide. The auxiliary pipe element 7 comprises an abutment 33, for example a nut or a shoulder, for axially positioning the element 7 with respect to the flange 14. When mounting the element 7 on the main pipe 6, the abutment of the element 7 bears on the flange 14, for example against the axial shoulder formed in the passage 32, so as to form a rigid connection.

Les éléments de connexion femelle 9 et mâle 10 ont des formes de révolution autour de l'axe AA'. Selon l'invention, les éléments 9 et 10 prolongent l'élément de tube principal 6 en augmentant l'épaisseur et la section externe du tube, pour former respectivement les épaulements 13 et 14. De préférence, la section extérieure des éléments 9 et 10 varie progressivement le long de l'axe 8, de manière à éviter une variation brusque de section entre le tube 6 et les épaulements 13 et 14 qui fragiliserait la tenue mécanique du connecteur 5. Par exemple, en référence à la figure 2, les éléments 13 et 14 forment des congés de rayon R1 et R2.The female 9 and male connection elements 10 have forms of revolution about the axis AA '. According to the invention, the elements 9 and 10 extend the main tube element 6 by increasing the thickness and the outer section of the tube, to form respectively the shoulders 13 and 14. Preferably, the outer section of the elements 9 and 10 progressively varies along the axis 8, so as to avoid a sudden variation in section between the tube 6 and the shoulders 13 and 14 which would weaken the mechanical strength of the connector 5. For example, with reference to the figure 2 the elements 13 and 14 form fillet of radius R1 and R2.

Les moyens de fixation 30 permettent de bloquer les translations axiales d'un élément 7 dans un sens, les moyens de fixation 31 permettent de bloquer les translations axiales d'un élément 7 dans le sens opposé. La combinaison des moyens de fixation 30 avec les moyens de fixation 31 permet de solidariser complètement l'élément 7 par rapport à l'élément de tube principal 6. Ainsi, les éléments 7 participent, conjointement avec l'élément de tube principal 6 à la reprise des efforts longitudinaux appliqués à la colonne 1.The fixing means 30 make it possible to block the axial translations of an element 7 in one direction, the fastening means 31 make it possible to block the axial translations of an element 7 in the opposite direction. The combination of the fixing means 30 with the fastening means 31 makes it possible to completely secure the element 7 with respect to the main pipe element 6. Thus, the elements 7 participate, together with the main pipe element 6 at the recovery of the longitudinal forces applied in column 1.

La forme et, en particulier, l'épaisseur e1 et e2 des brides 13 et 14 sont déterminées pour supporter les efforts longitudinaux transmis aux éléments de conduite auxiliaire 7.The shape and, in particular, the thickness e1 and e2 of the flanges 13 and 14 are determined to support the longitudinal forces transmitted to the auxiliary pipe elements 7.

Les éléments 7 de lignes auxiliaires sont raccordés bout à bout au moyen de raccords. Un raccord est composé d'un embout mâle 40 situé à une extrémité de l'élément 7 et d'un embout femelle 41 situé à l'autre extrémité de l'élément 7. Un embout mâle 40 coopère de façon étanche avec l'embout femelle 41 d'un autre élément 7. Par exemple, l'élément mâle 40 du raccord est une partie tubulaire qui s'insère dans une autre partie tubulaire 41. La surface intérieure de l'embout femelle 41 est ajustée à la surface extérieure de l'embout mâle 40. Des joints sont montés dans des rainures usinées sur la surface intérieure de l'élément femelle 41 afin d'assurer l'étanchéité de la liaison. Le raccord autorise un déplacement axial d'un des éléments 7 par rapport à l'autre, tout en maintenant la liaison étanche entre les deux éléments.The elements 7 of auxiliary lines are connected end to end by means of connectors. A connector is composed of a male endpiece 40 located at one end of the element 7 and a female endpiece 41 located at the other end of the element 7. A male endpiece 40 cooperates sealingly with the endpiece female 41 of a Other element 7. For example, the male member 40 of the connector is a tubular portion that fits into another tubular portion 41. The inner surface of the socket 41 is fitted to the outer surface of the spigot 40 Seals are mounted in grooves machined on the inner surface of the female member 41 to seal the connection. The connection allows axial movement of one of the elements 7 relative to each other, while maintaining the sealed connection between the two elements.

L'élément de conduite auxiliaire 7 peut être réalisé par l'assemblage de plusieurs pièces. L'élément 7 est composé du tube 7a qui est sensiblement de même longueur que l'élément 6. Le tube 7a est prolongé à son extrémité par les pièces d'usures 7b et 7c. Par exemples, les pièces 7b et 7c sont vissées sur le tube 7a. La pièce 7b comporte les éléments de fixation 30 et l'embout 40. La pièce 7c comporte les éléments de fixation 31 et l'embout 41. Les pièces 7b et 7c peuvent être changées indépendamment du tube 7a, par exemple en cas d'usure. De plus, les pièces 7b et 7c permettent de faciliter le montage des éléments 7 sur l'élément 6. Les pièces 7b et 7c peuvent être respectivement introduites dans l'orifice 32 pratiqué dans la bride 14 et l'orifice 33 pratiqué dans la bride 13. Puis, on visse le tube 7a sur les pièces 7b et 7c jusqu'à ce que les pièces 7b et 7c viennent respectivement en butée contre les brides 14 et 13.The auxiliary pipe element 7 can be made by assembling several parts. The element 7 is composed of the tube 7a which is substantially the same length as the element 6. The tube 7a is extended at its end by the wear parts 7b and 7c. For example, the parts 7b and 7c are screwed on the tube 7a. The part 7b comprises the fastening elements 30 and the end piece 40. The part 7c comprises the fastening elements 31 and the end piece 41. The parts 7b and 7c can be changed independently of the tube 7a, for example in case of wear . In addition, the parts 7b and 7c make it easier to assemble the elements 7 on the element 6. The parts 7b and 7c can be introduced into the orifice 32 formed in the flange 14 and the orifice 33 made in the flange, respectively. 13. Then, the tube 7a is screwed on the parts 7b and 7c until the parts 7b and 7c respectively abut against the flanges 14 and 13.

Le fait de disposer la bague 22 entre l'élément mâle 10 et l'élément femelle 9 permet une organisation plus compacte du connecteur 5. La position de la bague 22 permet de réduire l'encombrement du connecteur dans la direction radiale. En conséquence, on peut limiter l'écartement, par rapport à l'axe AA', des éléments 7 disposés à la périphérie du connecteur 5. En- conséquence l'écartement réduit de l'élément 7 par rapport à l'axe AA' permet de minimiser les efforts de flexion auquel sont soumis les brides 13 et 14. En effet, les brides 13 et 14 transmettent, et donc supportent, les efforts longitudinaux qui sont repris par les éléments 7. L'écartement des éléments 7 par rapport à l'axe AA' constitue un bras de levier qui, couplé aux efforts longitudinaux repris par les éléments 7, induisent des efforts de flexion dans les brides 13 et 14. Le connecteur compact selon l'invention permet de minimiser les efforts de flexion dans les brides, et donc de réduire les dimensions des brides 13 et 14 et d'alléger le poids des connecteurs.The fact of arranging the ring 22 between the male element 10 and the female element 9 allows a more compact organization of the connector 5. The position of the ring 22 makes it possible to reduce the size of the connector in the radial direction. Consequently, it is possible to limit the spacing, relative to the axis AA ', of the elements 7 disposed at the periphery of the connector 5. Consequently, the reduced spacing of the element 7 with respect to the axis AA' allows to minimize the bending forces to which the flanges 13 and 14 are subjected. Indeed, the flanges 13 and 14 transmit, and therefore support, the longitudinal forces which are taken up by the elements 7. The spacing of the elements 7 with respect to the axis AA 'constitutes a lever arm which, coupled with the longitudinal forces taken up by the elements 7, induce bending forces in the flanges 13 and 14. The compact connector according to the invention makes it possible to minimize the bending forces in the flanges, and therefore to reduce the dimensions of the flanges 13 and 14 and to lighten the weight of the connectors.

De plus, le dispositif selon l'invention offre une solution intéressante pour monter rapidement et simplement une colonne montante dont les efforts de tensions sont répartis entre les éléments de tubes auxiliaires et le tube principal. En effet, bien que les élément de tubes auxiliaires 7 et l'élément de tube principal 6 soient montés de manière à supporter conjointement les efforts de tension appliqués à la colonne, la connexion d'un tronçon 4 de colonne montante à un autre tronçon 4 de colonne montante est réalisée en une opération au moyen de la bague 22. Cette connexion permet de mettre en communication et de rendre étanche l'élément de tube principal d'un tronçon avec celui de l'autre tronçon et, simultanément, de mettre en communication et de rendre étanche les éléments de conduites auxiliaires d'un des tronçons avec ceux de l'autre tronçon.In addition, the device according to the invention offers an interesting solution to quickly and simply mount a riser whose tensioning forces are distributed between the auxiliary tube elements and the main tube. Indeed, although the auxiliary tube elements 7 and the main tube element 6 are mounted so as to jointly support the voltage forces applied to the column, the connection of a section 4 of the riser to another section 4 riser is made in one operation by means of the ring 22. This connection makes it possible to connect and seal the main tube element of one section with that of the other section and simultaneously to communication and seal the auxiliary pipe elements of one section with those of the other section.

Par ailleurs, le fait que la bague 22 soit positionnée entre l'élément 9 et l'élément 10 permet d'augmenter la tenue du connecteur. En effet, la bague 22 est maintenue mécaniquement du côté intérieur par le logement pratiqué dans l'élément 10. De plus, en position verrouillée, les tenons de la bague 22 sont en prise avec les tenons de l'élément 9 qui sont positionnés sur la partie massive de l'élément 9.Moreover, the fact that the ring 22 is positioned between the element 9 and the element 10 makes it possible to increase the resistance of the connector. Indeed, the ring 22 is mechanically held on the inside by the housing made in the element 10. In addition, in the locked position, the tenons of the ring 22 are engaged with the tenons of the element 9 which are positioned on the massive part of the element 9.

Le diamètre extérieur du tronçon de tube 10c est sensiblement égal au diamètre intérieur de la bague 22 de manière à pouvoir monter la bague 22 sur la partie 10c. La partie 10c est montée solidairement à l'élément de tube 6, par exemple par soudure. L'extrémité de la partie 10c comporte un épaulement 27 qui sert de butée à la bague 22. L'épaulement 14 est constitué par la deuxième partie 10d de forme annulaire. Le diamètre intérieur de la partie 10d correspond au diamètre extérieur du tronçon de tube 10c de manière à pouvoir monter la partie 10d sur la partie 10c. La bague est en butée entre la partie 10d et l'épaulement 27 de la surface extérieure de la partie 10c. La partie 10e est un anneau qui maintient la partie 10d et la bague 22 contre l'épaulement 27. Par exemple, la partie 10e est une vis qui s'engage sur des filets pratiqués sur la surface extérieure du tronçon 10c.With reference to the figure 5 , the male connection element 10 is made in three parts. Part 10c has the shape of a tube section which extends the main tube element 6. The outer diameter of the tube section 10c is substantially equal to the inside diameter of the ring 22 so as to mount the ring 22 on the part 10c. The portion 10c is integrally mounted to the tube member 6, for example by welding. The end of part 10c comprises a shoulder 27 which serves as a stop for the ring 22. The shoulder 14 is constituted by the second portion 10d of annular shape. The inner diameter of the portion 10d corresponds to the outer diameter of the pipe section 10c so as to mount the portion 10d on the portion 10c. The ring is in abutment between the portion 10d and the shoulder 27 of the outer surface of the portion 10c. Part 10e is a ring which holds the portion 10d and the ring 22 against the shoulder 27. For example, the portion 10e is a screw which engages on threads made on the outer surface of the section 10c.

En référence à la figure 5, l'élément de connexion femelle 9 comporte une surface d'appui 28 perpendiculaire à l'axe AA' du tronçon 4 et orientée vers l'élément de connexion mâle 10. Cette surface d'appui permet de maintenir, en suspend sur la table de rotation, la portion de colonne montante en cours d'assemblage.With reference to the figure 5 , the female connection element 9 comprises a bearing surface 28 perpendicular to the axis AA 'of the section 4 and oriented towards the male connection element 10. This support surface makes it possible to hold, suspended on the table of rotation, the riser portion being assembled.

En référence à la figure 5, l'élément de conduite auxiliaire 7 est réalisé par l'assemblage de plusieurs pièces. L'élément 7 est composé du tube 7d qui est sensiblement de même longueur que l'élément 6. Le tube 7d est prolongé à ses extrémités par les pièces 7e et 7f. Les pièces 7e et 7f sont soudées au tube 7d. La pièce 7e comporte un épaulement qui est en butée contre l'épaulement 13 de l'élément de connexion femelle 9. La pièce 7g, qui est vissée sur la pièce d'extrémité 7f, sert de butée à l'élément 7 contre l'épaulement 14.With reference to the figure 5 , the auxiliary pipe element 7 is formed by the assembly of several parts. The element 7 is composed of the tube 7d which is substantially of the same length as the element 6. The tube 7d is extended at its ends by the parts 7e and 7f. The parts 7e and 7f are welded to the tube 7d. The part 7e comprises a shoulder which abuts against the shoulder 13 of the female connecting element 9. The part 7g, which is screwed on the end piece 7f, serves as a stop for the element 7 against the shoulder 14.

Pour réaliser la connexion du connecteur selon l'invention, on peut effectuer les opérations suivantes.

  • Opération 1 :
    • La bague 22 est maintenue en position ouverte par un système de verrouillage.
    • On présente l'élément mâle 10 d'un tronçon face à l'élément femelle 9 d'un autre tronçon. Par exemple, l'élément femelle 9 est suspendu sur une table de manutention et l'élément 10 est manoeuvré par des moyens de levage.
    • La position des éléments de conduite auxiliaire 7 permet de positionner angulairement l'élément 10 par rapport à l'élément 9.
  • Opération 2 :
    • On fait coulisser longitudinalement l'élément mâle 10 dans l'élément femelle 9 jusqu'à ce que les deux éléments soient emboîtés et en butée l'un contre l'autre.
    • Lors de l'engagement de l'élément 10 dans l'élément 9, d'une part, les tenons de la bague 22 glissent entre les tenons de l'élément 9 comme décrit ci-dessus, et, d'autre part, les embouts mâle 40 des éléments 7 pénètrent dans les embouts femelle 41 des éléments 7.
  • Opération 3 :
    • Lorsque l'élément 10 est emboîté dans l'élément 5, on libère la bague 22 en rotation en agissant sur le système de verrouillage, puis on fait pivoter la bague 22 autour de l'axe du connecteur. La rotation de la bague 22 est effectuée jusqu'à atteindre une position fermée, c'est-à-dire jusqu'à ce que les tenons de la bague 22 soient positionnés en face des tenons de l'élément femelle 9. Le système de verrouillage peut limiter la rotation de la bague.
    • Lorsque la bague 22 est en position fermée, on immobilise la bague par rapport à l'élément 9 en agissant sur le système de verrouillage.
To make the connection of the connector according to the invention, the following operations can be performed.
