Title (EN) SAFETY INTEGRITY LEVELS (SIL) RATED SYSTEM FOR BLOWOUT PREVENTER CONTROL
(FR) SYSTÈME D'ÉVALUATION DE NIVEAUX D'INTÉGRITÉ DE SÛRETÉ (SIL) POUR COMMANDE D'OBTURATEUR ANTI-ÉRUPTION
Abstract:
(EN) A control system for a subsea blowout preventer (BOP, 12) positioned in a lower stack (14), the lower stack releasably engaged with a lower marine riser package (LMRP, 18). The control system includes a surface logic solver (38) positioned at or adjacent the surface of the sea that generates commands for operating the subsea BOP, a first subsea logic solver (40) attached to the LMRP and in communication with the surface logic solver so that the first subsea logic solver receives the commands from the surface logic solver, and a second subsea logic solver (44) attached to a hydraulic control unit (34) in the lower stack. The second subsea logic solver is in hydraulic communication with the subsea BOP, and the first subsea logic solver so that the second subsea logic solver receives the commands from the first subsea logic solver and implements the commands by activating the hydraulic control unit to operate the BOP.
(FR) La présente invention concerne un système de commande pour un obturateur anti-éruption (BOP, 12) sous-marin positionné dans un empilement (14) inférieur, l'empilement inférieur étant mis en prise amovible avec un ensemble colonne montante marine inférieure (LMRP, 18). Le système de commande comprend un résolveur logique de surface (38) positionné au niveau de la surface de la mer ou à proximité de celle-ci et qui génère des instructions de fonctionnement du BOP sous-marin, un premier résolveur logique sous-marin (40) fixé au LMRP et qui est en communication avec le résolveur logique de surface, de sorte que le premier résolveur logique sous-marin reçoive les instructions du résolveur logique de surface, et un second résolveur logique sous-marin (44) fixé à une unité de commande hydraulique (34) dans l'empilement inférieur. Le second résolveur logique sous-marin est en communication hydraulique avec le BOP sous-marin et avec le premier résolveur logique sous-marin, de sorte que le second résolveur logique sous-marin reçoive les instructions en provenance du premier résolveur logique sous-marin et mette en œuvre les instructions en activant l'unité de commande hydraulique pour faire fonctionner le BOP.
