Who can recommend some companies that specialize in the inspection of control systems?
We’re going to start Emerson’s inspection right away
This is usually handled by the system manufacturer’s after-sales service, but of course there are also companies outside that can do it. If you need to perform inspections on Yokogawa DCS systems, you can turn to me.
I need a company with maintenance qualifications from CNPC or Sinopec, and the bidding process is also required. We do have those from Yokogawa
System manufacturers generally offer inspection services
It depends on which company you use to develop your system; it’s best to have that company carry out the inspections, as they are more familiar with their own systems and it’s easier to communicate and address any issues.
It’s best to have the system manufacturer conduct an inspection. They certainly have the most say in their own system. Since their system was purchased and used, it must be a recognition of them as well. Does not recognizing someone’s qualifications mean they can’t use his system?
Qingdao Haitian Weiyeh is said to be able to carry out inspections on control systems for various brands; its advantages lie in better service compared to the manufacturers and a high cost-performance ratio
I have worked with the engineers and managers at Qingdao Haitian Weiyeh on site; it’s a good company – they are capable of carrying out DCS inspections for many manufacturers
I know that there are some inspection items for Lishih’s services
