(FR) RACCORD D'USURE POUR UN SYSTÈME DE RACCORDEMENT ET PROCÉDÉ D'INSTALLATION D'UN TEL RACCORD D'USURE
Abstract
(EN)
The present invention relates to a subsea fluid flow tubular connection system with an inboard hub 2 in fluid connection with piping of a subsea hydrocarbon exploration or production system and an outboard hub 3. The subsea fluid flow tubular connection system comprise a tubular saver sub 1 with an inboard hub connecting portion in sealing contact with the inboard hub 2 at a first end and an outboard hub connecting portion in sealing contact with the outboard hub 3 at a second end. A method of installing and exchanging such a tubular saver sub 1 is also disclosed.

La présente invention concerne un système de raccordement tubulaire d'écoulement de fluide sous-marin avec un moyeu intérieur 2 en connexion fluidique avec une tuyauterie d'un système d'exploration ou de production d'hydrocarbures sous-marin et un moyeu extérieur 3. Le système de raccordement tubulaire d'écoulement de fluide sous-marin comprend un raccord d'usure tubulaire 1 avec une partie de raccordement de moyeu intérieur en contact étanche avec le moyeu intérieur 2 au niveau d'une première extrémité et une partie de raccordement de moyeu extérieur en contact étanche avec le moyeu extérieur 3 au niveau d'une deuxième extrémité. L'invention concerne également un procédé d'installation et d'échange d'un tel raccord d'usure tubulaire 1.
