The control system for surface BOP stacks is important equipment for the controlling of BOP stacks,choke and kill valve for well control. The products not only meet the requirements of domestic standards but also has gotten the certification of API SPEC 16D.
MSP/DRILEX offers all the necessary blow out preventers control systems including accumulators,power assemblies, manifolds and control panels with accessories for remote operation. We can customize BOP control system to meet our customer requirements and offer API 16D monogram system.
The system is equipped with two groups of pump, electric , pump with different flow rate ,and air-operated oil pump which ensures the system to work normally in case of power failure.
The design of accumulator unit meets the requirement of closing all BOP stacks and opening hydraulic valve.If any accumulator bottle filed, the total liquid loss will not exceed 25%. MSP/DRILEX can offer the accumulator with ASME mark that complies with the requirements of API SPEC 16D.
The pressure of annular preventer circuit in control system may be adjusted by remote air-operated regulation.It characters reverse adjusting. In case of sudden failure of air supply , the pressure can be reset to the initial set value
The system may be provided with an alarm device. It monitors the accumulator pressure, air supply pressure and the liquid level in oil tank.When the above parameters excueed the alarm limits ,the signal of sound and light will be given.
The control manifold of the remote control panel is equipped with an orifice as an inlet of the pressure source . For example , the nitrogen backup system offered by MSP/DRILEX provides emergent auxiliary energy. If the accumulator and/or the pump can not provide the control manifold with enough power fluid,the nitrogen backup system may be used to provide high-pressure air to close the preventer. The nitrogen backup system can provide emergency air supply to the driller’s panel and the auxiliary control panel.
