Abstract:
An apparatus for controlling hydraulically actuatable components of a blowout preventer stack assembly and a system for same. The apparatus comprises a blowout preventer stack including hydraulically actuatable components and a lower marine riser package coupled to the blowout preventer stack and including additional hydraulic components. The lower marine riser package includes a solenoid valve configured to control at least some of the components. The solenoid valve receives hydraulic fluid from a dedicated accumulator or accumulator bank configured to supply hydraulic fluid exclusively for use with the solenoid valve. A closed-loop hydraulic circuit is formed between the accumulator or accumulator bank and the solenoid valve.
