摘要： A system and method to allow backup or alternate fluid flow routes around malfunctioning components using removable, modular component sets. In one exemplary embodiment, an ROV (106) establishes a backup hydraulic flow to a BOP (22) function by attaching one end of a hose to a modular valve block (18, 77) and the other end to an intervention shuttle valve (16), thus circumventing and isolating malfunctioning components. A compound intervention shuttle valve (16) is provided that comprises first (100) and second (600) primary inlets, first (101) and second secondary inlets (601), and an outlet (50). A modular valve block is provided that comprises a directional control valve (40, 42), a pilot valve (41, 43), a manifold pressure regulator (45), a pilot pressure regulator (46), stab type hydraulic connections and an electrical wet-make connection (410).
