Abstract:
1. A BOP fluid supply apparatus, comprising: a main source of hydraulic fluid; a BOP function; a primary fluid flow route from the main source of hydraulic fluid, through a primary component assisting in operating the BOP function, through a first valve, through a second valve, and then to the BOP function; and a secondary fluid flow route from the main source of hydraulic fluid, through an isolation valve rigidly fixed to the BOP, through a pilot-operated hot spare valve rigidly fixed to the BOP, through a hose removably connected to an intervention panel, through the second valve, and to the BOP function, wherein the secondary fluid flow route bypasses the primary component assisting in operating the BOP function and the first valve and provides hydraulic fluid to operate the BOP function; wherein the primary fluid flow route comprises a blue pod primary fluid flow route and the secondary fluid flow route comprises a blue pod secondary fluid flow route; and further comprising a yellow pod primary fluid flow route from the main source of hydraulic fluid, through a yellow pod primary component assisting in operating the BOP function, through the first valve, through the second valve, and then to the BOP function; and a yellow pod secondary fluid flow route from the main source of hydraulic fluid, through a yellow pod isolation valve rigidly fixed to the BOP, through a shuttle valve connected to the blue pod isolation valve, through the pilot-operated valve, through the hose connected to the intervention panel, through the second valve, and to the BOP function, wherein the yellow pod secondary fluid flow route bypasses the yellow pod primary component assisting in operating the BOP function and the first valve.
