Abstract

Une conduite flexible sous-marine (11) a un tube imperméable aux fluides (13) entouré par une structure de conduite (21). La structure de conduite (21) est un élément cylindrique monolithe. Il a au moins deux rangées de fentes (23) s'étendant le long de la paroi. Les fentes (23) sont espacées à intervalles réguliers, parallèlement les unes aux autres et en formant une hélice (31). Chacune de ces fentes est dans une rangée, également située sur une hélice (25) mais s'étendant dans une direction différente de l'hélice à fentes (31). Des bandes solides (27) s'étendent entre les rangées de fentes (23). Des éléments d'arc (33) se trouvent entre chacune des fentes, les éléments d'arc (33) joignant les bandes (27). La structure de conduite (21) entoure un tube imperméable aux fluides (13) qui est ondulé.
