250.449—What additional BOP testing requirements must I meet?

You must meet the following additional BOP testing requirements:
(a) Use water to test a surface BOP system;
(b) Stump test a subsea BOP system before installation. You must use water to conduct this test. You may use drilling fluids to conduct subsequent tests of a subsea BOP system;
(c) Alternate tests between control stations and pods;
(d) Pressure test the blind or blind-shear ram BOP during stump tests and at all casing points;
(e) The interval between any blind or blind-shear ram BOP pressure tests may not exceed 30 days;
(f) Pressure test variable bore-pipe ram BOPs against the largest and smallest sizes of pipe in use, excluding drill collars and bottom-hole tools;
(g) Pressure test affected BOP components following the disconnection or repair of any well-pressure containment seal in the wellhead or BOP stack assembly;
(h) Function test annular and ram BOPs every 7 days between pressure tests;
(i) Actuate safety valves assembled with proper casing connections before running casing;
(j) Test all ROV intervention functions on your subsea BOP stack during the stump test. You must also test at least one set of rams during the initial test on the seafloor. You must submit test procedures with your APD or APM for District Manager approval. You must:
(1) ensure that the ROV hot stabs are function tested and are capable of actuating, at a minimum, one set of pipe rams and one set of blind-shear rams and unlatching the LMRP; and
(2) document all your test results and make them available to BOEMRE upon request;
(k) Function test autoshear and deadman systems on your subsea BOP stack during the stump test. You must also test the deadman system during the initial test on the seafloor.
(1) You must submit test procedures with your APD or APM for District Manager approval.
(2) You must document all your test results and make them available to BOEMRE upon request.
