Abstract

L'invention vise à créer des conditions destinées à mettre en valeur un gisement situé à une profondeur inatteignable aux plate-formes de n'importe quel autre type, par l'acheminement de chambres étanches à l'intérieur desquelles est monté un équipement ainsi que de gaines étanches, reliées à ces chambres et comportant des canalisations du système de transport, et de gaines comportant des câbles d'alimentation et de commande, ce qui permet de les utiliser même dans des conditions météo défavorables, au-dessus de l'eau ou avec une couche de glace infranchissable ou des icebergs. Selon l'invention, le déplacement des chambres étanches à l'intérieur desquelles est monté un équipement ainsi que des gaines étanches, reliées à ces chambres et comportant des canalisations du système de transport, et des gaines comportant des câbles d'alimentation et de commande est effectué après le raccordement des sections subséquentes du système de transport de l'ensemble dans un boîtier de montage et le réglage de la profondeur d'immersion de toutes les groupes sous-marins de l'ensemble, qui se fait grâce au branchement répété de pompes assurant le transfert dosé du liquide à l'intérieur de blocs à pontons, reliés aux canalisations du système de transport de l'ensemble.
