Phasing in DCS migration
“I’ve got the go-ahead to upgrade our old DCS. The maintenance cost savings alone let me to justify this, but funds are still tight. I’ve got to phase this change over in across several budgeting periods. I’m concerned that I’ll have communication problems between the different DCS generations and have operator training issues. They’ll be working on two systems at the same time. What have I gotten my self into?”
Since there are so many processing facilities with just about unsustainable, old automation systems and tight budgets this can be expected to be a fairly common refrain for the next several years. A recent article in InTech magazine, “Phasing in DCS Migration (600KB PDF),” features Bolivia’s Cohasco gas plant that had these same issues. They used OPC to help the different generations of DCSs talk to one another and discus how they addressed operator training issues. If you are facing these issues you may find answers and perhaps a bit of reassurance in their successful solution to these problems.
