Title (EN) IMPROVEMENTS RELATING TO PIPELAYING
(FR) PERFECTIONNEMENTS SE RAPPORTANT À LA POSE DE CONDUITES
Abstract:
(EN) An in-line accessory structure for a subsea pipeline comprises an elongate pipe section arranged to be integrated into the pipeline, hence defining a flow axis through the structure. A branch has a lower end in fluid communication with the pipe section and an upper end in fluid communication with a connector hub. The structure further comprises a subsea foundation such as a mudmat, arranged to support the structure in an installed orientation. When the structure is in that orientation, the branch inclines inwardly from its lower end toward its upper end in a transverse direction, toward an upright longitudinal plane containing the flow axis.
(FR) La présente invention concerne une structure d'accessoire en ligne pour une conduite sous-marine, ladite structure comprenant une section de tuyau allongé conçue pour être intégrée dans la conduite, définissant ainsi un axe d'écoulement à travers la structure. Une ramification présente une extrémité inférieure en communication fluidique avec la section de tuyau et une extrémité supérieure en communication fluidique avec un collet de raccord. La structure comprend en outre une fondation sous-marine, telle qu'un patin, conçue pour supporter la structure dans une orientation installée. Lorsque la structure est dans cette orientation, la ramification s'incline vers l'intérieur depuis son extrémité inférieure vers son extrémité supérieure dans une direction transversale, vers un plan longitudinal vertical contenant l'axe d'écoulement.
