What tasks are required for storage and transportation when a refinery is shut down?

Oil removal, wire cleaning, and any issues that arise during production requiring shutdown for repairs must be fixed, etc

1. When shutting down the facility, it is necessary to first ensure smooth operations in the future by following the overall shutdown plan for the facility, and oil receiving tanks need to be prepared in advance. 2. In conjunction with the requirements of various storage and transportation departments regarding the maintenance or modification of valves in pipelines, a pipeline cleaning procedure should be established to avoid redundant work. 3. When cleaning internal floating roof tanks, the pressure must be well controlled to prevent damage to the floating disk. 4. Cylinders that are to be cleaned with steam require enhanced inspection; such cleaning should not be carried out on rainy days to prevent the oil cylinders from collapsing. 5. Keep proper records of the water top line, and mark it out before and after construction to prevent pipeline cracking due to freezing in winter. 6. The storage and transportation department shall cooperate with the plant shutdown plan, ensure proper control over the pipelines at the water level for line cleaning, and prepare a table for confirmation. 7. Carry out dehydration operations on the oil tanks that receive the scoured water; control the water level gauge and the amount of water, and be careful not to remove oil along with the water, in order to ensure environmental protection. 8. During the shutdown process, the plant scheduling team must work closely with the storage and transportation scheduling team, and assign dedicated personnel to go to the site for verification. 9. The pipelines at the water top of the scanning system can be contracted out, with dedicated personnel and specialized channels assigned to carry out inspections.
