1.2.6 Procedure for Maintenance and Care of LNG Tanks

LNG station operation technicians must be familiar with the structure and principles of the storage tanks and strictly adhere to the operational procedures for all LNG-related activities.

2. Operators of liquefied natural gas must be familiar with the performance and principles of the storage tank accessories (pressure gauges, level gauges, temperature gauges, vacuum gauge valves).

3. LiquidationNatural Gas Storage TankThe outer cylinder is a pressure-vacuum vessel, welding operations under vacuum are strictly prohibited.

4. Regularly inspect the outer cylinder of the storage tank for signs of icing or frost formation. Upon discovery, promptly report to the on-duty supervisor and station master. The on-duty supervisor or station master should immediately contact the manufacturer to identify the cause and initiate immediate action. Closely monitor any changes in the icing or frost formation during the process. If there is a tendency for the incident to escalate, immediately proceed with tank emptying or halt the filling operation, and close the relevant emergency shut-off valves at the inlets and outlets.

5. Regularly inspect the storage tank's connecting pipes and valves, observing for frost formation. Report any issues to the on-duty supervisor immediately, who will then arrange for personnel to address the situation.

6. Regularly inspect the tank's pressure gauge, level gauge, and thermometer to observe if the readings are normal.

7. Regularly inspect the sealing performance and operation of the connecting valves to ensure normal functioning.

8. Regularly inspect and calibrate safety valves, pressure gauges, level gauges, and thermometers as per regulations to ensure proper operation and promptly update the equipment inventory records.

9. Regularly perform anti-corrosion treatment on the outer cylinder of the storage tank and carry out visual cleaning and maintenance of the tank's pressure gauge, level gauge, and thermometer.

10. Regularly perform rust removal and anti-corrosion treatment on the susceptible rust areas, such as the pressure and level control instruments' three-way valves of storage tanks.

11. Conduct annual or operational vacuum level inspections of the storage tanks to monitor their operational status.
