Fewer unplanned shutdowns
Operators catch drift within the safe operating envelope, before alarm thresholds are crossed. Acting on a drift signal costs less than recovering from a trip.
Spot process drift before it triggers a shutdown.
For chemical processing, refining, and energy teams running continuous process units with many live sensor feeds.
A shift with Offset, step by step.
Walkthrough: an operator manages a distillation column as feed composition changes.
1
Before alarm threshold
Offset spots baseline drift.
A changing feed composition appears in two process variables. Both stay within normal alarm limits, but their shared trend matches patterns preceding a deviation event. Offset flags it before the first alarm fires.
2
Recommendation appears
Adjust reflux ratio. Three signals cited.
Offset recommends increasing reflux ratio to 1.3. It cites the feed composition trend, column pressure differential, and a DCS historian pattern from a comparable event 14 weeks prior. Confidence: 84%. The operator reviews the rationale in under 10 seconds.
3
Operator acts
Recommendation followed, with no override needed.
Using the existing DCS console, the operator adjusts the PLC setpoint. Offset records the action, operator ID, and timestamp. The P&ID parameter returns to its normal range within 12 minutes, before an alarm would have fired.
4
Shift handover
Incoming operator has full context.
Exact timestamps and data inputs accompany the logged recommendation and response. The incoming operator opens the audit trail and reviews the full sequence without a verbal briefing. No reconstruction needed.
What industrial operations teams gain.
Faster shift handover
The audit trail shows incoming operators what happened on the prior shift, including Offset's recommendation, the action taken, and the rationale, without relying on a verbal briefing.
COMAH and HSE records
The recommendation and response logs support UK HSE incident reporting and COMAH safety case documentation requirements. Compliance reports require less manual work.
What Offset connects to in a typical process plant.
Offset remains read-only across safety interlock and process control systems. It never writes to, overrides, or interferes with any safety system.

Pilot one process unit.
We typically connect 3 to 5 data sources per process unit for a pilot. Setup takes under a week. You assess recommendation quality over 30 days before committing.
