Low‐pressure Test Between 200 and 300 psi
High‐pressure Test for ram‐type BOPs, Rated working pressure of equipment;
the choke manifold, and other BOP or
components 500 psi greater than the calculated
MASP for the applicable hole section
(with MMS approval of those test
pressures)
High‐pressure Test for annular‐type 70‐percent of the rated working
BOPs pressure of the equipment; or a
pressure approved in the APD
Figure 14 – BOP Pressure Tests

If the equipment failed to hold the required pressure during any of these tests,
the operator was required to correct the problem and retest the affected
component.

5. Additional BOP Tests

At the time of the blowout, the regulation included additional subsurface
BOP testing requirements, including the following:

 Stump test of a subsea BOP system with water before installation;
 Alternate test between control stations and pods;
 Pressure test of the BSR during stump test and at all casing points;
 An interval between any BSR pressure test not exceeding 30 days;
 A pressure test of test variable bore‐pipe rams against the largest and
smallest sizes of pipe in use, excluding drill collars and bottom‐hole tools;
 A pressure test of affected BOP components following the disconnection
or repair of any well‐pressure containment seal in the wellhead or BOP
stack assembly;
 A function test of annulars and rams every seven days between pressure
tests; and
 Actuation of safety valves assembled with proper casing connections
before running casing.
