BOP Control Syetem
Control System for Surface Mounted BOP Stacks
The FKQ series surface control system will be designed,manufactured,and inspected as per API Spec 16D, and SY/T5053.2-2001. The corresponding surface control devices here are available for all specs of BOP stacks, main components of Triplex Plunger Pump, pneumatic pump, 3-position 4-way hydraulic switch valve, manual pneumatic regulating valve can be produced in machining center, the above products are of compact structure, low noise, good sealing stability, and easy operation, providing safety and security equipments for oil field.
Principle Description
A wide range of models of surface control devices with full function can be manufactured, volume of accumulator is from 125L to 1440L, and controlled objects are 2 to 14, besides the normal products function of all components,we can design special types according to client’s requirement. The BOP control system is also suitable for atrocious weather.
The system is equipped with two independent pump groups. According to number of controlled objects, we provide electric, pneumatic, or manual pump with different flow rate. Accumulator unit is designed to meet the requirement of closing all BOP stacks and opening hydraulic valve, (in case of a group of accumulator units fails to work, the total loss will not exceed 25%). We can offer accumulator with ASME Mark that complies with the requirement of API 16D.
The pressure of annular preventer circuit in control system may be adjusted by pneumatic regulator. It characters reverse adjusting. In case of sudden failure of air supply, the pressure can be reset to the present value automatically.
The control manifold of the remote control panel is equipped with an orifice as an inlet of the pressure source. For example, the spare nitrogen system offered by manufacturer provides emergent auxiliary energy. If accumulator or pump can not provide the control manifold with enough power fluid, the spare nitrogen system may be used to provide high pressure air to close the preventer. The spare nitrogen system may provide emergency air supply for the driller’s panel and the auxiliary control panel.
The system can be equipped with an alarm device. It monitors the accumulator pressure, air supply pressure and the liquid level in the oil reservoir. When the above parameters exceed the alarm limits, the audible and visual signal will appear timely.
The auxiliary control panel which adopts pneumatic control can be equipped with to monitor the remote control panel with air hose bundle or cable. Therefore, the system can be operated and monitored by both driller’s panel and auxiliary control panel.
The system can also be equipped with electric heating device of oil reservoir and air hose bundle. The system can also be equipped with a metal enclosure with exposing-proof electric heating board and explosion-proof air conditioner.
