(a) All wells shall have a fail shut-in capability. For pumping wells incapable of natural flow to the ocean floor, an approved power source shut-off system may be used. On all flowing or gas lift wells the wellhead assemblies shall be equipped with an automatic failclose valve.

(b) All flowlines from wellheads shall be equipped with high-low pressure sensors located close to the wellhead. The pressure sensors shall be set to shut-in the well in the event of abnormal pressures in the flowline.

(c) All headers shall be equipped with check valves on the individual flowlines. The flowline and valves from each well located upstream of, and including, the header valves shall withstand the shut-in pressure of that well, unless protected by a relief valve with connections to bypass the header. If there is an inlet valve to a separator, the valve, flowline, and all equipment upstream of the valve shall also withstand shut-in wellhead pressure, unless protected by a relief valve with connections to bypass the header.

(d) All pneumatic, hydraulic, and other shut-in control lines shall be equipped with fusible material at strategic points.

(e) Remote shut-in controls shall be located on the helicopter deck and all exit stairway landings leading to the helicopter deck and to all boat landings. These controls shall be quick-operating devices.

(f) All pressure sensors shall be operated and tested for proper pressure settings monthly. Results of all tests shall be recorded and maintained on the structure or facility.

(g) All automatic wellhead safety valves shall be tested for holding pressure monthly. Results of all tests shall be recorded and maintained on the structure or facility.

(h) Check valves shall be tested for holding pressure monthly for at least four months. At such time as the monthly results are satisfactory, a quarterly test shall be required. Results of all tests shall be recorded and maintained on the structure or facility.

(i) A standard procedure for testing of safety equipment shall be filed with the Division and posted in a prominent place on the structure or facility.
