Working with operators 1

[PetarKnezevich]

Hi,

I'm a chemical process engineer working in oil & gas. I often have to review operating envelopes and I sometimes have difficulty conveying information to operators regarding complex systems.

Could I get your comments and suggestions on good ways get information across?

I have attached a simple chart that I once produced for control room team when I had to put a restriction on the entry pressure into a gas pipeline based on the arrival pressure at a downstream station (PSVs were chattering because the operating pressure was too close to the set pressure).

The graph is a simple (to me) way to find the desired pipeline inlet pressure to maintain the downstream station pressure below 86 barg depending on the pipeline flow rate. It is based on the actual pressure, temperature and flow data from the data historian.

Regards,
Petar

P.S. We changed to pilot operated PSVs and that solved the chattering problem.

Give an example on a second graph.

Good luck,

put on your hard hat and safety equipment and get involved in a half-dozen turn-arounds, with that under you belt, assuming you survive, you'll find your communication with operating staff considerably improved

That could have been easily handled with a single loop controller. A good operator knows that, so they also knew an Engineer could have fixed it once and saved them from having to adjust it all the time.

Good luck,
