The Challenge

A utility provider operated a waste gas twin-screw compressor with a complex startup procedure requiring two or more operators. Because the process relied heavily on manual execution, startups were inconsistent and often required multiple attempts. These repeated attempts placed unnecessary mechanical stress on the compressor, and in some cases had already led to rotor damage.

Startup delays didn't just affect one asset, they impacted the entire site utility system, increasing operational risk during critical recovery scenarios.

  • Complex manual startup requiring multiple operators
  • Frequent failed startup attempts due to human variability
  • Mechanical stress leading to past rotor damage
  • Startup delays affecting overall site utilities

The Approach

The team transformed startup performance from operator-dependent execution into a data-defined best practice.

  • Historical startup mining: Value-based searches were used to quickly identify and layer all past startup events
  • Pattern clustering: Visual clustering analysis grouped time-series profiles to detect consistent startup ramps
  • Best practice discovery: Subject-matter experts identified a cluster representing highly stable and predictable startups
  • Human factor insight: Analysis showed these optimal startups were consistently executed by a specific senior operator
  • Golden fingerprint creation: The best-performing startup patterns were converted into a reference profile
  • Automation enablement: The fingerprint was used to guide and standardize future startups, reducing variability and failed attempts
Startup profile comparison — current data vs. ideal golden fingerprint

Key Insight

Startup success was not random, it followed a repeatable pattern. Once captured as a fingerprint, that expertise could be replicated across operators.
