Title (EN) CONTROL SYSTEMS AND METHODS FOR SUBSEA ACTIVITIES
(FR) SYSTÈMES ET PROCÉDÉS DE COMMANDE POUR ACTIVITÉS SOUS-MARINES
Abstract: front page image
(EN)A control system is for completion installation, intervention and testing activities at a subsea location. The control system has a first control circuit at a surface location; a subsea test tree located in a blowout preventer at the subsea location, the second control circuit located within a riser extending from the blowout preventer towards the surface location; and a plurality of sensors monitoring characteristics of the subsea location. The second control circuit communicates with the first control circuit and receives the characteristics of the subsea location. The second control circuit also controls electrically powered subsea valves based upon commands from the first control circuit and based upon the characteristics of the subsea location to complete a completion installation, intervention, and/or testing activity.
(FR)L'invention porte sur un système de commande, lequel sert à la réalisation d'activités d'installation, d'intervention et de test en un emplacement sous-marin. Le système de commande a un premier circuit de commande en un emplacement de surface ; un arbre d'essai sous-marin disposé dans un obturateur anti-éruption au niveau de l'emplacement sous-marin, le second circuit de commande étant disposé à l'intérieur d'une tube prolongateur s'étendant à partir de l'obturateur anti-éruption vers l'emplacement de surface ; et une pluralité de capteurs contrôlant des caractéristiques de l'emplacement sous-marin. Le second circuit de commande communique avec le premier circuit de commande et reçoit les caractéristiques de l'emplacement sous-marin. Le second circuit de commande commande également des électrovannes sous-marines sur la base d'ordres à partir du premier circuit de commande et sur la base de caractéristiques de l'emplacement sous-marin de façon à réaliser une activité d'installation, d'intervention et/ou de test.
