Abstract
A subsea blowout preventer control system has horizontally oriented solenoid valve housings. Solenoid valves mounted within each of the solenoid valve housings are electrically controlled to selectively provide a hydraulic pilot signal to a hydraulic valve. A vertically extending central chamber contains a dielectric liquid and extends alongside the solenoid valve housings. A communication tube for each solenoid valve housing has an open upper end within the central chamber adjacent an upper end of the central chamber. Each of the communication tubes has an open lower end extending into one of the solenoid valve housings for communicating dielectric liquid in the central chamber with an interior of each of the solenoid valve housings. A separate drain line mounted to each of the solenoid valve housings enables draining of one of the solenoid valve housings for maintenance without requiring draining of other of the solenoid valve housings.
