Abstract:
1. A BOP fluid supply apparatus, comprising: a main source of hydraulic fluid; a primary component assisting in operating a plurality of BOP functions; at least one BOP function; a primary fluid flow route from the main source of hydraulic fluid, through the primary component assisting in operating the at least one BOP function, through a first valve, through a second valve, and then to the BOP function; and a secondary fluid flow route from a source of hydraulic fluid originating downstream of the primary component assisting in operating the at least one BOP function leading to an isolation valve rigidly fixed to the BOP, then on 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 backs up the primary component and assists in operating the at least one BOP function and the first valve and provides hydraulic fluid to operate the BOP function.
