Abstract

The equipped deck (1) is charged onto a self-elevating platform (2). The platform is positioned close to the fixed platform (11) and the deck is lifted from the self-elevating platform (2) to the level of the fixed platform (11). The deck is slid on the fixed platform (11) by means of a cradle (6) mounted on blocks provided with regulating jacks. The blocks co-operate with sliding ways provided on each of the platforms. The two platforms are coupled by means of a guiding frome (12).

Description

L'invention concerne un procédé de transport et de transfert d'une charge constituée d'un équipement complet d'un pont de plate-forme marine fixe consistant à monter la totalité des installations d'un pont dans un chantier à terre, à transférer l'équipement complet sur des moyens de transport remorqués sur le site et à transférer ledit équipement sur le pont de la plate-forme à équiper.The invention relates to a method for transporting and transferring a load consisting of complete equipment for a fixed marine platform bridge, consisting in mounting all the installations of a bridge in a shore yard, to be transferred complete equipment on means of transport towed to the site and to transfer said equipment to the deck of the platform to be equipped.

L'infrastructure des plates-formes est généralement construite à terre, en une ou plusieurs parties qui sont remorquées sur le site, assemblées, puis immergées par contrôle de leur flottabilité. Le pont est ensuite équipé des installations correspondant à la destination de la plate-forme. Ces installations sont réalisées à partir de modules de poids et de dimensions standards, qui sont assemblés les uns aux autres in situ. Dans les mers à conditions climatiques normales, le levage et la mise en place des modules sont réalisés par des grues barges et des engins semi-submersibles classiques. Par contre l'utilisation de ces mêmes engins dans des mers aux conditions climatiques difficiles ne permet pas une efficacité suffisante pendant les très courtes périodes où les conditions atmosphériques autorisent le travail dans des conditions de sécurité suffisantes. Afin de diminuer les temps nécessaires au levage et à la mise en place des éléments et par conséquent de diminuer les risques climatiques, ainsi que les coûts de manutention et autres dépenses directes, on a cherché à augmenter la capacité de levage des grues barges et des semi-submersibles mais l'on a atteint une limite au-delà de laquelle les engins sont si coûteux que leur rentabilité ne peut être obtenue que par un taux d'utilisation journalier important. Malheureusement l'amortissement de ces engins ne peut être envisagé que sur quelques projets.The infrastructure of the platforms is generally built on the ground, in one or more parts which are towed on the site, assembled, then submerged by checking their buoyancy. The bridge is then equipped with the installations corresponding to the destination of the platform. These installations are made from modules of standard weights and dimensions, which are assembled together in situ. In seas with normal climatic conditions, the lifting and the installation of the modules are carried out by barge cranes and conventional semi-submersible machines. On the other hand, the use of these same devices in seas with difficult climatic conditions does not allow a sufficient efficiency during the very short periods when the atmospheric conditions authorize the work in conditions of sufficient safety. In order to reduce the time required to lift and install the elements and therefore to reduce the climatic risks, as well as the handling costs and other direct expenses, we sought to increase the lifting capacity of barge cranes and semi-submersible but a limit has been reached beyond which the machines are so expensive that their profitability can only be obtained by a high rate of daily use. Unfortunately the depreciation of these machines cannot only be considered on a few projects.

Il subsiste en outre des inconvénients sérieux dus aux procédés employés, ainsi les risques, inhérents à tout levage en mer, augmentent proportionnellement au poids levé, de même que ceux dûs au transfert d'une charge d'un engin flottant à une installation fixe.There are also serious drawbacks due to the methods used, so the risks inherent in any lifting at sea increase proportionally to the weight lifted, as well as those due to the transfer of a load from a floating object to a fixed installation.

Le temps nécessaire à l'installation des équipements, à leur essai et à leur réception n'en est pas pour cela diminué.The time required to install the equipment, to test it and to receive it is not therefore reduced.

L'installation fait appel à un grand nombre de personnes qui doivent s'accomoder de conditions d'habitat difficiles aggravées par les conditions climatiques.The installation appeals to a large number of people who have to live with difficult housing conditions made worse by climatic conditions.

Une solution à ces problèmes a été trouvée pour certaines plates-formes, et en particulier pour des plates-formes à embase poids et des plates-formes autoélévatrices, consistant à faire l'installation complète du pont ainsi que la réception du matériel dans le chantier de construction et à remorquer sur le site l'ensemble plate-forme et pont installé.A solution to these problems has been found for certain platforms, and in particular for weight-bearing platforms and jack-up platforms, consisting in making the complete installation of the bridge as well as the reception of the material on the site. of construction and to tow the installed platform and bridge assembly on site.

Ce mode de construction limite les possibilités d'utilisation de la plate-forme à celles initialement prévues et la transformation, par exemple, d'une plate-forme de forage en plate-forme de production n'est pas envisageable de manière simple, une bonne partie des installations devant être démontée et remplacée.This construction method limits the possibilities of using the platform to those initially planned and the transformation, for example, of a drilling platform into a production platform is not possible in a simple way, a a good part of the installations must be dismantled and replaced.

Le procédé, selon l'invention, vise à permettre le transfert de la totalité des équipements nécessaires à l'aménagement du pont d'une plate-forme dont l'infrastructure est déjà en place sur le site, les équipements étant montés et ayant subi la réception finale sur un chantier à terre.The method according to the invention aims to allow the transfer of all the equipment necessary for fitting out the bridge of a platform whose infrastructure is already in place on the site, the equipment being mounted and having undergone final acceptance on a shore site.

Selon l'invention, le transport et le transfert des équipements sont réalisés à partir d'une plate-forme autoélévatrice susceptible d'être reliée pour le chargement ou le déchargement au quai d'embarquement et à la plate-forme à équiper.According to the invention, the transport and transfer of the equipment is carried out from a self-elevating platform capable of being connected for loading or unloading to the embarkation platform and to the platform to be equipped.

Les explications et figures données ci-après à titre d'exemple permettront de comprendre comment l'invention peut être réalisée.

  • La figure 1 représente la phase de transfert de l'équipement d'un quai à une plate-forme auto- élévatrice.
  • La figure 2 est une vue de dessus de la figure 1 montrant une partie des moyens de transfert.
  • La figure 3 représente la phase de transfert de l'équipement d'une plate-forme autoélévatrice à la plate-forme à équiper.
The explanations and figures given below by way of example will make it possible to understand how the invention can be implemented.
  • FIG. 1 represents the phase of transferring the equipment from a quay to a jack-up platform.
  • Figure 2 is a top view of Figure 1 showing part of the transfer means.
  • FIG. 3 represents the phase of transfer of the equipment from a jack-up platform to the platform to be equipped.

La figure 1 montre schématiquement la phase de transfert d'un équipement complet 1, monté et réceptionné à terre, sur une plate-forme 2 autoélévatrice. De manière connue, la plate-forme autoélévatrice est amarrée au quai 3 de manière que les moyens de transfert prévus sur le pont de la plate-forme soient approximativement dans le prolongement de ceux du quai. Ces moyens de transfert sont constitués respectivement de chemins 4 et de rails 5 de glissement. Le berceau 6, qui forme une partie des moyens de transfert et qui supporte l'équipement, constitué des locaux d'habitation, des locaux techniques et éventuellement de la tour de forage, est monté sur des supports de transfert constitués, par exemple, de cinq rangées de trois patins 7 également espacées selon ce que l'on conviendra d'appeler la longueur du berceau. L'espacement des patins sur une rangée correspond à l'espacement des rails 5 et des chemins 4 de glissement. Les patins sont montés sur des vérins plats de manière à permettre éventuellement un transfert des charges d'une rangée de patins aux autres rangées de patins comme il sera ultérieurement décrit.Figure 1 schematically shows the transfer phase of a complete equipment 1, mounted and received ashore, on a self-elevating platform 2. In known manner, the self-elevating platform is moored to platform 3 so that the transfer means provided on the deck of the platform are approximately in line with those of the platform. These transfer means consist respectively of paths 4 and sliding rails 5. The cradle 6, which forms part of the transfer means and which supports the equipment, consisting of living quarters, technical premises and possibly the drilling tower, is mounted on transfer supports constituted, for example, of five rows of three pads 7 also spaced according to what will be called the length of the cradle. The spacing of the pads on a row corresponds to the spacing of the rails 5 and the paths 4 of slip. The pads are mounted on flat cylinders so as to allow possible transfer of the loads from one row of pads to the other rows of pads as will be described later.

Afin d'assurer l'alignement au moins approximatif entre les rails 5 et les chemins 4 de glissement de la plate-forme, il est prévu un gabarit 8 que l'on dispose entre le quai 3 et le pont de la plate-forme 2. Ce gabarit porte des guides 9 qui relient les rails 5 aux chemins 4.In order to ensure at least approximate alignment between the rails 5 and the sliding tracks 4 of the platform, a template 8 is provided which is placed between the platform 3 and the deck of the platform 2 This template carries guides 9 which connect the rails 5 to the paths 4.

Le transfert de l'équipement s'opère, dans cet exemple de manière connue, par glissement. Mais à ce stade du procédé de transport tous autres moyens ou méthodes peuvent être utilisés et même éventuellement le levage par grue ou portique. Le chargement, s'opérant en zone côtière généralement calme, ne présente pas de difficultés particulières.The transfer of the equipment takes place, in this example in a known manner, by sliding. But at this stage of the transport process any other means or method can be used and even possibly lifting by crane or gantry. The loading, taking place in a generally calm coastal zone, does not present any particular difficulties.

La plate-forme autoélévatrice 2 de transport est maintenue en flottaison pour la réception de la charge. Il n'est toutefois pas exclu de la faire reposer sur ses pieds 10.The self-elevating transport platform 2 is kept floating for receiving the load. It is not however excluded to make it rest on its feet 10.

Dans le transfert par glissement, on évite que le gabarit 8 disposé entre le quai et la plate-forme ne supporte de charge.In the transfer by sliding, it is avoided that the template 8 disposed between the platform and the platform does not support a load.

Pour ce faire, la charge supportée par la rangée de patins arrivant sur le gabarit entre le quai 3 et la plate-forme 2, est transférée aux autres rangées de patins qui reposent soit sur le quai, soit sur la plate-forme autoélévatrice.To do this, the load supported by the row of pads arriving on the template between the platform 3 and the platform 2, is transferred to the other rows of pads which rest either on the platform or on the jack-up platform.

Lorsque la plate-forme autoélévatrice 2 est chargée, elle est remorquée sur le site puis arrimée près de la plate-forme fixe 11.When the jack-up platform 2 is loaded, it is towed to the site and then stowed near the fixed platform 11.

On positionne la plate-forme 2 de manière à mettre approximativement ses moyens de transfert en alignement avec ceux prévus sur la plate-forme 11, puis on lève le pont de la plate-forme autoélévatrice 2 au niveau du pont de la plate-forme fixe 11. On accouple les deux ponts par un châssis de guidage 12 qui a pour fonction de maintenir les positions relatives des plates-formes l'une par rapport à l'autre dans le plan horizontal.The platform 2 is positioned so as to approximate its transfer means in alignment with those provided on the platform 11 , then the bridge of the jack-up platform 2 is raised at the level of the bridge of the fixed platform 11. The two bridges are coupled by a guide frame 12 which has for function of maintaining the relative positions of the platforms relative to each other in the horizontal plane.

On opère le transfert de la charge 1, de la plate-forme autoélévatrice 2 à la plate-forme fixe 11, de manière connue, par glissement.The transfer of the load 1 is carried out from the jack-up platform 2 to the fixed platform 11, in a known manner, by sliding.

La rangée de patins s'engageant sur le châssis 12 entre les deux plates-formes est délestée de la charge au profit des autres rangées de patins reposant sur l'un ou les deux ponts,The row of skids engaging on the chassis 12 between the two platforms is relieved of the load in favor of the other rows of skates resting on one or both bridges,

Lorsque le transfert de la charge est terminé, les deux ponts sont désaccouplés par retrait du châssis de guidage 12.When the transfer of the load is complete, the two bridges are uncoupled by removing the guide frame 12.

On met la plate-forme autoélévatrice en flottaison en remontant ses pieds et on en dispose en vue d'autres utilisations et notamment celle-ci peut être équipée d'une grue et de quartier d'habitation de façon à exécuter éventuellement la fin des travaux.We put the self-lifting platform in flotation by raising our feet and we have it for other uses and in particular it can be equipped with a crane and living quarters so as to eventually carry out the end of the work .

Il est à remarquer que les chemins de glissement 4 prévus aussi bien sur la plate-forme fixe que sur la plate-forme autoélévatrice sont relativement larges par rapport aux patins 7 du berceau 6 portant la charge. Ceci permet un décalage transversal du module lors du transfert dû, par exemple, à un défaut de positionnement des chemins des deux ponts, décalage qui est facilement rattrapable lors du glissement.It should be noted that the sliding paths 4 provided both on the fixed platform and on the self-elevating platform are relatively wide compared to the pads 7 of the cradle 6 carrying the load. This allows a transverse offset of the module during transfer due, for example, to a positioning defect of the paths of the two bridges, an offset which is easily compensated for during sliding.

La modification de destination de la plate-forme fixe est aisément réalisable en tranéférant, selon le même procédé, l'équipement du pont de la plate-forme fixe au pont de la plate-forme autoélévatrice et en le remplaçant lors d'un transfert ultérieur par un équipement adapté à la nouvelle utilisation de la plate-forme fixe.Changing the destination of the fixed platform is easily achievable by transferring, using the same process, the equipment from the bridge of the fixed platform to the bridge of the jack-up platform and replacing it during a subsequent transfer by equipment adapted to the new use of the fixed platform.
