Description
La présente invention concerne un système multi-outils utilisable pour le raccordement de conduites flexibles ou rigides et, plus particulièrement pour l'inspection, le nettoyage et le remplacement d'organes dans des installations pétrolières sous-marines.The present invention relates to a multi-tool system usable for the connection of flexible or rigid pipes and, more especially for inspection, cleaning and replacement organs in underwater oil installations.
Dans l'industrie pétrolière et plus particulièrement dans l'exploitation pétrolière en mer, loin des côtes, les installations sous-marines sont parfois à de grandes profondeurs atteignant 1 000 m et même davantage. Pour réaliser des connexions entre divers ensembles des installations sous-marines, sans faire appel à des plongeurs ou à des techniques similaires, on utilise, de plus en plus, certains types de robots télécommandés depuis la surface (ROV en anglais, acronyme de Remotely Operated Vehicle) qui sont capables de transporter et/ou de déplacer des charges plus ou moins lourdes et d'effectuer des opérations diverses et variées telles que des connexions entre des éléments et des installations sous-marines.In the petroleum industry and more particularly in offshore oil exploitation, far from the coast, underwater installations are sometimes at great depths reaching 1000 m and even more. To make connections between various sets of underwater installations, without the need for divers or similar techniques, we are using more and more certain types of robots remotely controlled from the surface (ROV in English, acronym of Remotely Operated Vehicle) which are capable of transporting and / or moving more or less heavy loads and to perform various operations and varied such as connections between elements and installations submarines.
Les systèmes de connexion connus sont réalisés de sorte que les moyens de raccordement sont montés dans un dispositif d'extrémité qui est solidaire de l'ensemble fixe. Lorsque les essais de vérification d'étanchéité effectués avant l'utilisation opérationnelle de la canalisation ou périodiquement en cours d'utilisation, sont défectueux, il est nécessaire de réparer ou changer les moyens de raccordement et, en particulier, les organes d'étanchéité. Dès lors, une ou plusieurs interventions compliquées et très onéreuses sont indispensables du fait que les organes nécessitant la ou les interventions sont disposés à l'intérieur de l'ensemble fixe.Known connection systems are designed so that the connection means are mounted in an end device which is integral with the fixed assembly. When the verification tests sealing performed before operational use of the pipeline or periodically in use, are defective, it is necessary repair or change the connection means and, in particular, the sealing members. Therefore, one or more complicated interventions and very expensive are essential because the organs requiring or the interventions are arranged inside the fixed assembly.
Pour remédier à ces inconvénients, la demanderesse a proposé, dans une demande déposée le 14 juin 1996 sous le n° 96 07 429 (FR-A-2 749 918), d'intégrer les moyens d'étanchéité et de verrouillage dans une cassette flottante qui constitue une interface entre les extrémités des conduites à raccorder, ladite cassette participant également au guidage et au centrage desdites extrémités à raccorder. To remedy these drawbacks, the applicant has proposed, in an application filed on June 14, 1996 under No. 96 07 429 (FR-A-2 749 918), integrate the sealing and locking means in a cassette floating which constitutes an interface between the ends of the pipes to connect, said cassette also participating in guiding and centering of said ends to be connected.
Toutefois, les utilisateurs préfèrent parfois monter les moyens de verrouillage soit sur l'extrémité fixe avant le raccordement soit sur les deux extrémités après raccordement.However, users sometimes prefer to mount the means either on the fixed end before connection or on the two ends after connection.
Une solution qui prend en compte cette considération de montage direct des moyens d'étanchéité tout en assurant un raccordement correct des extrémités des conduites à raccorder est décrite dans une autre demande de la déposante et portant le n° 97 06 314 (FR-A-2 763 636).A solution that takes this consideration of direct mounting of the sealing means while ensuring a connection correct of the ends of the pipes to be connected is described in another request of the applicant and bearing the number 97 06 314 (FR-A-2 763 636).
L'objet de cette dernière demande concerne notamment un réceptacle qui est solidaire de la structure fixe sur laquelle est montée une conduite flexible considérée comme fixe, ledit réceptacle recevant, à l'intérieur, les deux extrémités des conduites flexibles fixe et mobile à raccorder. A cet effet, le réceptacle comprend une paroi frontale et une paroi arrière pour le passage des extrémités des conduites, les dimensions internes dudit réceptacle étant choisies de telle sorte que l'espace intérieur soit suffisant pour déplacer entièrement les moyens de verrouillage des extrémités raccordées dans leur position finale de raccordement.The subject of this last request concerns in particular a receptacle which is integral with the fixed structure on which is mounted a flexible pipe considered to be fixed, said receptacle receiving, at inside, the two ends of the fixed and mobile flexible pipes to connect. For this purpose, the receptacle includes a front wall and a rear wall for passage of pipe ends, dimensions internal of said receptacle being chosen such that the interior space is sufficient to completely move the locking means of the ends connected in their final connection position.
Toutefois, il existe un besoin concernant l'inspection et/ou le nettoyage des faces en contact des extrémités des conduites avant la mise en place et/ou le changement des moyens d'étanchéité et/ou de verrouillage.However, there is a need for inspection and / or cleaning the contacting faces of the ends of the pipes before placing in place and / or changing the sealing means and / or locking.
En effet, jusqu'à présent, lorsqu'on doit mettre en place ou changer les moyens de verrouillage pour une raison quelconque, par exemple, par suite d'une usure prématurée ou normale, lesdits moyens de verrouillage sont tout simplement amenés dans leur position appropriée sans avoir procédé à une inspection des extrémités à raccorder. De la même manière, les organes d'étanchéité qui sont utilisés sur au moins une desdites conduites sont, après usure ou périodiquement, remplacés par des organes d'étanchéité neufs sans examen préalable des zones de support correspondantes. Or, en raison des fluides plus ou moins corrosifs qui peuvent circuler dans les conduites flexibles, il peut arriver que certaines parties d'une ou des deux conduites flexibles, situées dans la zone de raccordement, soient sinon endommagées du moins encrassées. Quand une intervention de nettoyage, par exemple, doit être effectuée, il n'y a, à l'heure actuelle, aucune solution susceptible de répondre à ce besoin. Même le caisson qui est disposé généralement sur la base du ROV et qui, en principe, contient des éléments nécessaires à une intervention sur le site ne contient pas d'outils spécifiques sauf ceux pour la manutention de certains organes de l'installation sous-marine, comme exemple l'enlèvement, la pose des moyens de verrouillage ou encore l'enlèvement et la pose des organes d'étanchéité.Indeed, until now, when we have to set up or change the locking means for any reason, for example example, as a result of premature or normal wear, said means of lock are simply brought into their proper position without having carried out an inspection of the ends to be connected. Of the same way, the sealing members that are used on at least one said pipes are, after wear or periodically, replaced by new sealing elements without prior examination of the support zones corresponding. However, due to the more or less corrosive fluids which can circulate in flexible pipes, it can happen that some parts of one or both flexible pipes, located in the area of connection, are otherwise damaged at least fouled. When a cleaning intervention, for example, must be carried out, there is, at At present, no solution is likely to meet this need. Even the box which is generally placed on the basis of the ROV and which, in principle, contains elements necessary for intervention on the site does not contain specific tools except those for handling certain parts of the underwater installation, as an example removal, installation of locking means or removal and fitting the sealing members.
La présente invention a pour but de proposer un système multi-outils ou unité d'intervention, qui peut être commandé par le ROV lorsqu'il est indépendant de ce dernier, c'est-à-dire non compris dans le ROV, ou qui peut être intégré dans le ROV, par exemple logé dans le caisson inférieur si cela est possible.The object of the present invention is to propose a multi-tool system or intervention unit, which can be ordered by the ROV when it is independent of the latter, that is to say not included in the ROV, or which can be integrated into the ROV, for example housed in the lower case if possible.
La présente invention a pour objet un système multi-outils pour l'inspection, le nettoyage et le remplacement d'organes dans une installation pétrolière, caractérisé en ce qu'il comprend un support sur lequel sont montés des moyens susceptibles de déplacer latéralement au moins deux dispositifs dans des directions opposées, au moins un desdits dispositifs étant susceptible d'être entraíné en rotation autour d'une desdites directions.The present invention relates to a multi-tool system for the inspection, cleaning and replacement of organs in a petroleum installation, characterized in that it comprises a support on which are mounted means capable of moving laterally to at least two devices in opposite directions, at least one of said devices being capable of being rotated around a of said directions.
Un avantage de la présente invention réside dans le fait qu'il est possible de procéder à une inspection des éléments ou organes disposés dans le réceptacle lorsque l'installation fixe en comporte un, avant toute intervention. Bien entendu, le même système peut être utilisé dans des installations sous-marines et comportant ou non un réceptacle.An advantage of the present invention is that it is possible to inspect the elements or organs arranged in the receptacle when the fixed installation has one, before any intervention. Of course, the same system can be used in underwater installations and whether or not including a receptacle.
Un autre avantage de la présente invention est qu'après l'inspection, le système peut effectuer, si besoin était, un nettoyage desdits éléments et/ou organes logés dans le réceptacle.Another advantage of the present invention is that after the inspection, the system can carry out, if necessary, a cleaning said elements and / or members housed in the receptacle.

Le fonctionnement de ce premier mode de réalisation du système multi-outils selon l'invention est le suivant.The operation of this first embodiment of the Multi-tool system according to the invention is as follows.
Après avoir écarté les deux extrémités 3 et 4 l'une de l'autre, le
système multi-outils est amené par le ROV dans le réceptacle 2, avec les
deux bras 9 et 10 dans leur position rapprochée, ainsi que représenté sur
la figure 1.After having separated the two
Dans une première phase (figure 2), le vérin 17 est actionné
pour mettre en extension la tige 18 qui pousse le bras 9 en le faisant
pivoter autour de son axe de pivotement 11 jusqu'à ce que le téton 24
vienne en butée au fond du trou oblong 16. Puis, sous l'action du vérin
