PRINIPLE DESCRIPTION:




The BOP Control Systems are all strictly designed, manufactured and inspected in accordance with China
National Standard SY/T5053.2-2001 & API SPEC 16D. Type selection, proper installation, connection and
maintenance of control system must following the instructions in the Operational Manuals.


More than 30 types of BOP control systems, whose
controlled objects are from 2 to 14, are suitable for any
different environments and weathers.

Besides the normal products described in FUNCTION
OF ALL COMPONENTS, we can also design special
types according to customer’s requirements.

The system is equipped with two pumps. Electric pump
with different flow rate, and pneumatic or manual pump
which ensure the system to work normally in case of
power failure. The design of accumulator unit meets the
requirements of closing all BOP stacks and opening
hydraulic valve. If any accumulator fails to work, the
total liquid loss will not exceed 25%. We can offer the
accumulator with ASME mark that complies with the
requirements of API 16D in request of customer’s
special
requirements. The pressure of annular preventer circuit in control system many be adjusted by pneumatic
regulator. It characters reverse adjusting. In case of sudden failure of air supply, the pressure can be reset to
the preset 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 provides emergent auxiliary
energy. If the accumulator or the pump can not provide the control manifold with enough power fluid, the
spare nitrogen system may be sued

 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 quipped 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 with adopts pneumatic control can be equipped with to monitor the remote
control panel. The auxiliary control panel is connected to 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.
