Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The following devices shall be installed and maintained
						in an operating condition at all times when the affected well (or wells) is
						producing. The operator shall maintain records on the structure or facility
						showing the present status and history of each such device, including dates and
						details of inspection, testing, repairing, adjustment, and reinstallation or
						replacement.
(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.
