Plantweb Insight apps are easy to set up and test on a variety of chemical processing installations, pose very low risk, and quantifying the payback is as easy as the initial deployment.
With manual procedures, operators perform the necessary actions either guided by their own years of experience or by a standard operating procedure (SOP) manual.Prompted operational procedures go one step further. Prompted procedures are implemented in the process automation system. The system asks the operator to acknowledge that each manual step has been completed successfully to be able to continue. Prompted procedures make it easier to keep electronic records, verify that procedures were followed correctly, and can help decrease transition times and procedural variability.
According to a study by the ASM Consortium, this accounts for approximately 42 percent of the unscheduled shutdowns in the process industries. Of that 42 percent, 14 percent relates directly to procedural errors. When researching the role of operators in the refinery of the future, several major operating companies concluded that they could address this by using a higher-level perspective on the entire production operation, one that supports intervention-by-exception to relieve the operator of many previously manually performed tasks and freeing them to perform more value-adding activities.
ARC Advisory Group has identified procedural automation, along with alarm management and an operational perspective, as a crucial process automation system function contributing to an environment of flawless operation. With procedural automation, the know-how and operating level of experienced operators can be incorporated into automatic sequences and used to standardize operating methods and improve the efficiency of all operators. Think of it as having the most experienced and most effective operator on the board all day, every day.
