(EN) SYSTEMS AND METHODS FOR ACCESSING SUBSEA CONDUITS
(FR) SYSTÈMES ET PROCÉDÉS D'ACCÈS À DES CONDUITS SOUS-MARINS
Abstract
(EN)
A system for remediating a blockage(120) in a subsea component (110) including a riser (60) extending from a surface vessel (12), a flexible jumper (70) having an upper end coupled to the riser and a lower end coupled to a subsea component (110), and a surface system (20) disposed on the surface vessel (12) and including flexible tubing (24) configured to be inserted and advanced through the tubular string (60) and flexible jumper (70) to the blockage (120).
(FR)
L'invention concerne un système pour remédier à un blocage (120) dans un composant sous-marin (110), comprenant une colonne montante (60) qui s'étend à partir d'un navire de surface (12), un cavalier souple (70) ayant une extrémité supérieure couplée à la colonne montante et une extrémité inférieure connectée à un composant sous-marin (110), et un système de surface (20) disposé sur le navire de surface (12) et comprenant un tube flexible (24) conch pour être inséré et avancé à travers la colonne tubulaire (60) et le cavalier souple (70) jusqu'au blocage (120).
