For any operation that requires the use of a BOP, you must include the information listed in this section with your applicable APD, APM, or other submittal. You are required to submit this information only once for each well, unless the information changes from what you provided in an earlier approved submission or you have moved off location from the well. After you have submitted this information for a particular well, subsequent APMs or other submittals for the well should reference the approved submittal containing the information required by this section and confirm that the information remains accurate and that you have not moved off location from that well. If the information changes or you have moved off location from the well, you must submit updated information in your next submission.

| You must submit: | Including: |
| --- | --- |
| (a) A complete description of the BOP system and system components, | (1) Pressure ratings of BOP equipment; |
| | (2) Proposed BOP test pressures (for subsea BOPs, include both surface and corresponding subsea pressures); |
| | (3) Rated capacities for liquid and gas for the fluid-gas separator system; |
| | (4) Control fluid volumes needed to close, seal, and open each component; |
| | (5) Control system pressure and regulator settings needed to close each ram BOP under MASP as defined for the operation; |
| | (6) Number and volume of accumulator bottles and bottle banks (for subsea BOP, include both surface and subsea bottles); |
| | (7) Accumulator pre-charge calculations (for subsea BOP, include both surface and subsea calculations); |
| | (8) All locking devices; and |
| | (9) Control fluid volume calculations for the accumulator system (for a subsea BOP system, include both the surface and subsea volumes). |
| (b) Schematic drawings, | (1) The inside diameter of the BOP stack; |
| | (2) Number and type of preventers (including blade type for shear ram(s)); |
| | (3) All locking devices; |
| | (4) Size range for variable bore ram(s); |
| | (5) Size of fixed ram(s); |
| | (6) All control systems with all alarms and set points labeled, including pods; |
| | (7) Location and size of choke and kill lines (and gas bleed line(s) for subsea BOP); |
| | (8) Associated valves of the BOP system; |
| | (9) Control station locations; and |
| | (10) A cross-section of the riser for a subsea BOP system showing number, size, and labeling of all control, supply, choke, and kill lines down to the BOP. |
| (c) Certification by an independent third party, | Verification that: (1) Test data demonstrate the shear ram(s) will shear the drill pipe at the water depth as required in [§ 250.732](/on/2024-09-16/title-30/section-250.732); (2) The BOP was designed, tested, and maintained to perform under the maximum environmental and operational conditions anticipated to occur at the well; (3) The accumulator system has sufficient fluid to operate the BOP system without assistance from the charging system; and (4) If using a subsea BOP, a BOP in an HPHT environment as defined in [§ 250.804(b)](/on/2024-09-16/title-30/section-250.804#p-250.804(b)), or a surface BOP on a floating facility, the BOP has not been compromised or damaged from previous service. |
| (d) If you are using a subsea BOP, descriptions of autoshear, deadman, and emergency disconnect sequence (EDS) systems, | A listing of the functions with their sequences and timing. |
