Plant production management strategies flawed?
A recent study provides strong evidence that process industry automation users are frustrated with the low success levels provided by current plant production management strategies
This includes comprehensive on-line diagnostics of all control valves.
Loop and valve diagnostics are performed utilising models created from a combination of real-time data and historical information (collected via OPC).
This important service is available for virtually all process control systems and all field devices.
Foundation fieldbus or other digital field protocols are not required.
Critical under-performing loops are prioritised for remediation, and if desired, Invensys process control experts can perform the actual loop tuning and recommend appropriate valve maintenance activities.
Following remediation, Invensys provides a report documenting the loop performance improvements that were achieved.
Ongoing remote monitoring, reporting, prioritisation and on-site remediation services are available to help ensure optimal loop performance over time.
"These new services fill a critical gap created when many process manufacturers made the decision to downsize their engineering, maintenance, and operations staffs in response to business pressures, said Harris Kagan, director of technology marketing at Invensys Process Systems.
"As a result of this downsizing, many process loops - including critical "money" loops - are often operating sub-optimally, resulting in decreased product quality, increased raw material and energy usage, or the need for frequent operator intervention.
Poorly performing control loops, and particularly oscillating loops, also often result in excessive valve wear, thus increasing maintenance requirements.
By off-loading day-to-day loop management to Invensys, process manufacturers can realise optimal control loop performance, while freeing typically overworked plant personnel to perform other critical plant tasks." =.
