§ 1747.1. Safety and Pollution Control Equipment Requirements.
The following requirements shall apply to all offshore production facilities. Sections 1747.3, 1747.4, and 1747.9 shall also apply to mobile drilling structures. Sections 1747.2 and 1747.10 shall also apply to ocean floor completions or wells with submerged wellheads.
(a) The following devices shall be installed and maintained in an operating condition on all pressurized vessels and water separation facilities when such vessels and separation facilities are in service. 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.
(4) All other hydrocarbon handling pressure vessels shall be equipped with high-low pressure shut-in sensors, high-low level shut-in controls, and relief valves, unless they are determined by the Supervisor to be otherwise protected. All low pressure systems connected to high pressure systems shall be equipped with relief valves.
(5) Pilot-operated pressure relief valves shall be equipped to permit testing with an external pressure source. Spring-loaded pressure relief valves shall either be bench-tested or equipped to permit testing with an external pressure source. A relief valve shall be set no higher than the designed working pressure of the vessel. On all vessels with a rated or designed working pressure of more than 400 psi, the high pressure shut-in sensor shall be set no higher than 5 percent below the rated or designed working pressure and the low pressure shut-in sensor shall be set no lower than 10 percent below the lowest pressure in the operating pressure range. On lower pressure vessels the above percentages shall be used as guidelines for sensor settings considering pressure and operating conditions involved, except that sensor setting shall not be within 5 psi of the rated or designed working pressure or the lowest pressure in the operating pressure range.
