Key Points of Oilfield Accumulator Unit 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.
