Abstract

La présente invention concerne un tube d'intervention enroulé qui peut être placé à l'intérieur d'une conduite d'écoulement sous-marine, par exemple avec un outil d'insertion sous-marin, pour remédier à des blocages dans la conduite d'écoulement sous-marine. Dans des modes de réalisation, l'outil d'insertion sous-marin est utilisé pour dérouler une longueur de colonne de tube d'intervention enroulé à partir d'un dévidoir de tube d'intervention enroulé et insérer la colonne de tube d'intervention enroulé non enroulée au niveau sous-marin dans une conduite d'écoulement vers laquelle une buse d'éjection est positionnée à proximité d'un blocage dans une conduite d'écoulement (120). Un fluide est fourni, par exemple pompé, d'une unité de pompage chimique (80) à une colonne de tube d'intervention enroulé (100) à travers une buse d'éjection (110) pour remédier au blocage dans la conduite d'écoulement (120).
