Abstract
(EN)
A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. All of the well barriers may be located within the tubing hanger and/or the production tubing string extending into the wellbore. The subsea wellhead assembly also includes a flowline connection body placed atop the wellhead housing and fluidly coupled to the tubing hanger. None of the primary barriers for the well are located in the flowline connection body.
(FR)
L'invention concerne un ensemble tête de puits sous-marin ayant un système de barrières de puits primaires disposées dans un équipement situé à l'intérieur du puits et/ou du logement de tête de puits. Toutes les barrières de puits peuvent être situées à l'intérieur de la suspension des tubes de production et/ou de la colonne de production s'étendant dans le puits de forage. L'ensemble tête de puits sous-marin comprend également un corps de raccordement de conduite d'écoulement placé au-dessus du logement de tête de puits et en communication fluidique avec la suspension des tubes de production. Aucune des barrières primaires pour le puits n'est située dans le corps de raccordement de la conduite d'écoulement.
