Well Control Bop Control Unit Remote Control
The accumulator unit for BOP stacks is a very important piece of
equipment that controls BOP stacks and gate valves controlled by
hydraulic pressure, especially in drilling and workover operations.
It is necessary to accurately operate and maintain the hydraulic
control system. It consists of remote control system, driller’s
panel, air cable (except electrical type), pipe rack (electrical
warming system available for cold area), high-pressure manifold,
protection room, etc.

Key Points of BOP Control System selection
To control BOP reliably and safely, oil & natural gas industry
standards SY/T5053.2-2007 and APl Spec 16D should be followed when
you choose and purchase a suitable product. Factors to be
considered should at least be:
- Relationship between liquid volume required for closing BOP stacks
and liquid volume available from the control system
- Requirements of pump system;
- Whether it needs to meet the APl 16D standards;
- Environmental adaptation;
- Special requirements on the off-shore drilling platforms.
1 Options for controlled objects and accumulator available liquid
volume
The accumulator group shall be configured so that the remaining
pressure is greater than the maximum control pressure required
by the control object after closing all BOP and hydraulic valves.
Available volume from an accumulator group is recommended be 2
times greater than the required volume of closing BOP stacks.
2. Requirements of pump system
The main pumping unit shall be comprised of a minimum of two pump
systems. The cumulative output capacity of the
pump systems shall be sufficient to charge the main accumulator
system from precharge pressure to the system RWP within
15 minutes. With the loss of one pump system or one power system,
the remaining pump system(s) shall have the capacity to
charge the main accumulator system from precharge pressure to the
system RWP within 30 minutes.
With the accumulators isolated from service and with one pump
system or one power system out of service, the remaining
pump system(s) shall have the capacity to close one annular BOP and
open choke valve(s) within 2 minutes.
3. Whether it needs to meet the API 16D standards
If the customer wants to order an API Spec. 16D control system, and
mark the API monogram, the customer need to obtain
a form named “configuration and parameters of the bop stacks for
order an API Spec. 16D control system (land and surface)”
from Rongsheng sales department. After filling in the detailed
technical parameters, the Rongsheng technical department will
carry out the selection calculation.
