Cathodic protection rectifiers shall be inspected by a qualified electrical inspector every three months. The output of the rectifiers shall be checked daily. The lessee shall maintain records on the production facility showing the daily output readings and the dates, details of inspection, and repairs to each rectifier.(5) Internal Corrosion Control. Where corrosion inhibitors are necessary to mitigate internal corrosion, they shall be used in sufficient quantities to protect the entire pipeline. The lessee shall use coupons or other monitoring equipment to determine the effectiveness of the inhibitors. The lessee shall, at intervals not exceeding six months, examine coupons or other corrosion-monitoring equipment to assure effectiveness of any inhibitors used.(6) Pipeline Inspections. (A) All unburied oil and gas pipelines shall be visually inspected annually by the lessee for damage, evidence of corrosion, and conditions that may be hazardous to the pipelines.(B) Where mechanically possible, all oil and gas pipelines shall be inspected annually by the lessee using an electronic survey tool. Upon request of the lessee, the frequency of inspection may be reduced depending upon the degree of corrosion observed.(C) If it is not mechanically possible to run an electronic survey tool, the lessee shall hydrostatically pressure test each oil and gas pipeline to at least 1.5 times its maximum operating pressure. The test procedure shall be approved by the Staff.(D) The ocean surface above all pipelines that service offshore facilities shall be inspected a minimum of once each week for indication of leakage, using aircraft or boats. Records of these inspections, including the date, methods, and results of each inspection, shall be maintained by the lessee at its nearest onshore office.(7) Reports of Inspection. The lessee shall file a report with the Staff describing the testing procedure and results of (1) the annual test of the cathodic protection system on each pipeline and (2) the annual visual and electronic inspection of hydrostatic test of each oil and gas pipeline. The reports shall be filed within 60 days following completion of the work.(8) Safety Equipment and Procedures. (A) All oil and gas pipelines receiving production from offshore production facilities shall be equipped with high-low-pressure shut-in sensors and with an automatic shut-in valve located at the offshore facility. The pressure sensors shall be connected so as to actuate the automatic shut-in valves on the pipelines as well as all shut-in devices on input sources to the pipelines. The pressure settings shall be determined by pipeline operating characteristics, and shall be set as close as practicable to the normal operating pressure of the pipeline. The automatic shut-in valves also shall be actuated by the integrated safety-control system of the production facility.(B) All oil and gas pipelines that deliver production to an onshore production facility shall be equipped with a remote-controlled shut-in valve or check valve at or near the receiving facility.(C) All oil and gas pipelines that cross an offshore facility which do not deliver production to the facility, and may or may not receive production from the facility, shall be equipped with an automatic shut-in valve to be located in the upstream portion of the pipeline at the facility, so as to prevent uncontrolled flow at the facility. This automatic shut-in valve shall be controllable by the integrated safety-control system of the facility.(D) Any pipeline that delivers gas to an offshore facility for the purpose of gas lift or other operations shall be equipped with an automatic shut-in valve to be located in the upstream portion of the pipeline at the facility, so as to prevent uncontrolled flow at the facility. This automatic shut-in valve shall be controllable by the integrated safety-control system of the facility.(E) All oil pumps and gas compressors shall be equipped with high-low-pressure shut-in devices.(F) All pressure sensors, pressure shut-in devices, and automatic shut-in valves shall be tested monthly by the lessee, and shall be witnessed and approved by the Staff. The lessee shall maintain records on the production facility showing the present status and past history of each device, including dates and details of inspection, testing and repairing, adjustment, and reinstallation or replacement.Cal.
