An apparatus to allow backup or alternate fluid flow routes around malfunctioning BOP control components using a remotely installed removable hydraulic hose connection. The backup fluid flow route sends pressure-regulated hydraulic fluid to a BOP operation via an isolation valve rigidly attached to the BOP, then to a hose connected to an intervention panel on the BOP and finally through a valve that isolates the primary flow route and establishes a secondary flow route to allow continued operation. To increase reliability, the backup components route from a spare BOP function and are rigidly fixed to the BOP.

L'invention concerne un dispositif pour permettre des chemins d'écoulement de fluide de secours ou alternés autour de composants de commande de bloc obturateur de puits (BOP) fonctionnant mal à l'aide d'un raccordement de tuyau hydraulique souple amovible installé à distance. Le chemin d'écoulement de fluide de secours envoie un fluide hydraulique régulé en pression pour un fonctionnement de BOP via une soupape d'isolement fixée de manière rigide sur le BOP, puis vers un tuyau souple relié à un panneau d'intervention situé sur le BOP et enfin à travers une soupape qui isole le trajet d'écoulement principal et établit un trajet d'écoulement auxiliaire pour permettre un fonctionnement continu. Pour augmenter la fiabilité, les composants de secours à partir d'un BOP de rechange agissent et sont rigidement fixés sur le BOP.
