Inspection items for the plant during shutdown
Thread Content
Due to poor performance, the plant was shut down. During this shutdown period, the crew did not need to work shifts around the clock; ensuring the safety of the plant through regular inspections became the main focus during this time. The inspection requirements during shutdown periods are certainly very different from those in production mode; we welcome all colleagues to discuss this issue: ① How should the equipment be inspected during shutdown periods? ②What are the precautions for inspections? ③In particular, how often should inspections be carried out on high platforms and tower tops, and what are the items to be inspected? 【Benefit】Floors rated ≥10 points by the moderators will receive a flower.
I wonder to what extent the system has reverted to its original state? Prevent thieves from entering; ensure nothing is missing at the site, check for any leaks; take precautions against freezing in winter; monitor the pressure, temperature, and liquid level of the material handling system.
Most of the equipment has been returned, but MTBE has not been returned. Now, two or three people are left in each shift, with four shifts operating on a three-shift rotation.
It is mainly for theft prevention and leakage prevention; daily inspections at the top of the tower on the ground are sufficient.
1. Items and equipment that are prone to being lost on-site should be stored in the warehouse. 2. Regular inspections should be carried out; if there are few staff members, inspections should take place every two hours during the day and every four hours at night, with proper records kept. 3. Tanks used for storing materials are key areas that require inspection – the liquid level and pressure must be checked each time, with records kept. 4. In the event of a long period of shutdown, measures must be taken to prevent freezing during winter

In case of long-term shutdowns, measures must be taken to prevent freezing during winter. Additional points: 1. Regularly turn the pumps manually. 2. Pay attention to any leaks at the connections of pipeline systems that do not have material flowing through them. 3. Take measures to protect against high temperatures in summer. 4. Ensure that tanks storing materials, as well as systems without flowing material, are properly treated to prevent static electricity and are equipped with lightning protection grounding
Key points of inspection include checking the liquid level and pressure at each inspection and recording the results, as well as looking for any leaks. In winter, measures must be taken to prevent freezing, and attention should also be paid to the pressure, temperature, and liquid level in the material handling systems. Regularly turn the pumps manually; take measures to prevent high temperatures in summer, and carry out static electricity control and lightning protection grounding for tanks storing materials as well as systems from which no materials are withdrawn!
1. During the shutdown of the facility, a duty system is implemented by the shutdown maintenance command center. The personnel on duty are assigned by the heads of various functional teams within the command center, who also remain on duty there. The duty hours are determined based on the progress of the maintenance work, as decided at the maintenance coordination meetings. 2. The personnel on duty at the command post carry out their responsibilities on behalf of the various functional teams of the maintenance command post during their shift. 3. During the shutdown for maintenance of the facility, all construction units must implement a 24-hour on-site duty system to enable timely handling of on-site issues and maintain order at the construction site. The on-duty personnel should remain in constant contact with the command center, and promptly coordinate and report on the progress of repairs, as well as matters related to quality, safety, and proper construction practices. 4. All units under inspection must also implement a 24-hour on-site duty system during maintenance work, in order to cooperate with the construction units to carry out the shutdown maintenance properly. 5. The duty personnel must remain at their posts, handle and coordinate promptly all issues that arise during maintenance work, and report major problems to the leadership of the command center without delay.
