Issues related to the renovation of the anti-riot control room
Thread Content
Our company is a petrochemical enterprise with 22 years of experience; it was established in 2001. The spacing between buildings and installations does not meet the current regulatory requirements, and the explosion-proof standards are also not fulfilled. Upon inspection by the safety supervision agency, these issues were identified as serious hazards, and the company is currently shut down for rectification. The company’s operations are average. To save money, a new riot control room was built at a distance that meets regulatory requirements, but there are many cables involved, and it’s not possible to afford to lay them all anew. What should be done? The current plan is to relocate the DCS cabinets to a new cabinet room, add intermediate junction cabinets in the original cabinet room, and use extension cables to connect the DCS cabinets. I’m not sure if there are any precedents for such an approach, and whether it will meet the requirements of the safety inspection agency experts.
Given your situation, it is recommended that you first consult experts from the safety supervision agency regarding the specific requirements and standards, so as to better understand how to rebuild your riot control room. At the same time, it is also possible to collaborate with some specialized companies in electrical engineering and explosion protection to find cost-reduction solutions. For example, you can consider using flame-retardant cables and other necessary equipment to ensure that your devices meet safety standards. Furthermore, you can also adjust the layout between cabinets according to actual conditions by using reconfigurable cable trays, cable channels, and other devices, thereby avoiding the need for extensive cable rerouting. Finally, it is recommended that you seek professional license approval services and maintain communication with the safety supervision agency throughout the process, to ensure that your control room meets all safety standards and regulatory requirements. -
The original control room was converted into an on-site cabinet room, and blast-resistant reinforcement measures were implemented. A new central control room was built; whether this room requires a blast-resistant structure is determined based on QRA analysis. Fiber optics are used to connect the on-site cabinet room to the newly built central control room
Move the control room; fiber optics will do. If the cabinet cannot be moved, it is also possible to provide shock resistance on site.
The explosion-proof control room has nothing to do with cabinets; the focus is on providing explosion protection for people, and it is sufficient as long as the control room where people operate meets the requirements regarding explosion-proof distances
Transfer in SIS/GDS cabinets, DCS fiber optic communication
We are carrying out construction based on Juge Company’s design: blast-resistant membranes are applied to the interior walls of the control room, along with blast-resistant doors
The cabinet servers are installed in the plant area to ensure durability, while the DCS control computers are placed in a control room outside the plant; signals are transmitted between them via fiber optics
The control room needs to be moved to a suitable area, and it is likely that blast-resistant design will be required. Keep the cabinet room in place; instead, use shock-resistant walls and explosion-proof doors. Hire qualified design and construction firms to handle this task to avoid complications during inspections. The control room contains only operation stations, and the switches between the operation stations and the cabinets use fiber optic communication. This isn’t difficult; an instrumentation engineer can handle it. If not, you can ask the DCS manufacturer for help in coming up with a solution.
Adding blast walls to the cabinet room is more expensive. We are now planning to add an intermediate junction box in the original cabinet room to handle this.
