Instrument Design Verification..

Hi all,

An oil & Gas Flow station which produces 10000 BOPD of oil ..Pretty Small plant.Has Separators, Heater treater,floatation Cell unit, K.O Drums, Pumps, flare, Tanks etc...

What all design verification and calculation can be done based on Instrumentation.

I could list out few:

Instrument range calculations, Installation checks,

Cause & Effect verification, Control Systems,F&G system, Valve sizing calculations, Hazardous area analysis..

Is it possible for you guys to add more design verification topics and possible evaluation on an oil & gas plant for design analysis for Instrumentation & Control System. ..

Thanks
