blowout preventer control device accumulator

902 Well Site Preparation and Drilling Safety

The accumulator is a storage device for nitrogen pressurized hydraulic fluid, which is used in operating the blowout preventers. The choke manifold is the arrangement of piping and special valves, called chokes, through which drilling mud is circulated when the blowout preventers are closed to control the pressures encountered during a kick.
