What are the performance characteristics of the blowout preventer control device?

The BOP remote console is equipped with two independent power supplies. According to different configurations, electric oil pumps, pneumatic oil pumps or manual oil pumps with different displacements are provided. The design of the accumulator group meets the control requirements of closing all BOP groups and opening hydraulic valves. The accumulator system is designed so that when one or a group of accumulators fail, the capacity loss does not exceed 25% of the total capacity, and accumulators with the inspection mark of the American Association of Mechanical Engineers can be provided. The pneumatic pressure regulating valve control device has a remote pneumatic pressure regulating function. When the air source suddenly fails, the control pressure can automatically return to the initial set value. There is a backup pressure source interface on the remote console control manifold, and a pressure source can be introduced when necessary. A nitrogen backup system can be provided as needed to provide emergency auxiliary energy for the control manifold. When the accumulator and/or pump device cannot provide enough power fluid for the control manifold, the nitrogen backup system can be used to provide high-pressure gas for the manifold to close the blowout preventer. The nitrogen backup system can also provide an emergency gas source for the drill floor and auxiliary console in an emergency.
