Patent ID: 7757772

Claim:
A hydraulic fluid supply apparatus for use with an underwater BOP system, comprising: a modular removable valve block having an inlet connected to a hydraulic fluid source and an outlet connected to a valve block stab connection; a plurality of intervention shuttle valves, each having a primary inlet hard piped to a hydraulic fluid supply line, a backup inlet connected to a backup inlet stab connection receiver, an outlet connected to a hydraulically operated BOP function, and a shuttle; a selectively engageable hose having a first end removably connectable to the valve block stab connection and a second end connectable to any one of the backup inlet stab connections; wherein the modular removable valve block further comprises: at least one directional control valve, the number of directional control valves corresponds to the same number BOP functions that the modular valve block may simultaneously serve; at least one pilot valve operatively coupled to the directional control valve; a manifold pressure regulator operatively coupled to the pilot valve, the manifold pressure regulator controls the supply pressure to components downstream of directional control valve; and, a pilot pressure regulator operatively coupled to the pilot valve.
