The control system for surface mounted BOP stacks is an important equipment for the control of BOP stacks, choke and kill valves in the drilling and work over drilling operations.

   The ground blowout preventer control system has large size and many controls and can be provided with multi-function alarming system, low-temperature heating system, nitrogen standby system, auxiliary control console and other devices.

Technical characteristics

   1 .Multi-models and functions especially design for customers, such as unit electrical control product etc.

2. The system is equipped with two pump groups. Electric pump with different flow rate , and air-operated oil pump which ensures the system to work normally in case of power failure. Its maximum theoretical flow rate may reach 46L/min.It may be equipped with appropriate pneumatic pumps of several specifications, so it can implement low-pressure startup and can guarantee the normal operation of the system even when the power supply is broken; it may be equipped with 50:1.

3 .The accumulator assembly has sufficient high-pressure liquid storage. The design of accumulator unit meets the requirement of closing all BOP stacks and opening hydraulic valve. If any accumulator bottle fails to work, the total liquid loss will not exceed 25%.

4 .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 automatically.

5 .Remained interface of backup pressure supply for the control manifold can supplement the pressure if needed, such as Nitrogen backup system. For example, the nitrogen backup system offered by BPM provides emergent auxiliary energy .If the accumulator and/or the pump cannot provide the control manifold with enough power fluid ,the nitrogen backup system may be used to provide high-pressure air to close the preventer.

6 .It can be equipped with an alarm device according to customers requires which is used to monitor the pressure of accumulators, air supply and liquid level of oil tank. When the above parameters exceed the alarm limits, the signal of sound and light well work.

7 .The system can be equipped with auxiliary control panel. Air-operated control is adopted of air control type and electric control of electric control type in the auxiliary control panel. The system may be operated by driller panel and/or auxiliary control panel.

8 .The system can also be equipped with electrical heating device of oil tank and air cable. FKQ-series control devices additionally can be equipped with auxiliary control console. The system may also be equipped with a housing with air-conditioner, explosion-proof electrical heating board and explosion-proof air-conditioner.

9 .Besides the products listed in the table, we can design special models according to the customer’s requirement.
