CASE 12 · CASE ATLAS · LEVEL B WORKSHOP SCENARIO

Pitch-system firmware change control

SITUATION

The turbine OEM has issued an updated pitch-controller firmware intended to reduce extreme-load events in high-turbulence sites. The asset owner must decide how to roll it out across a fleet without turning a safety-relevant software change into an uncontrolled fleet-wide experiment.

EVIDENCE

The firmware change note and its stated scope, the prior qualified configuration baseline, site-specific turbulence and load history, and the OEM's validation test report for the change.

AI APPROACH

Deterministic configuration-attestation checking confirms exactly which turbines are on which firmware revision against the intended rollout plan; retrieval surfaces the specific load-case and site parameters the OEM's validation actually covered, for the engineer to judge whether a given site falls inside or outside that tested envelope.

KEY CONTROLS

The tool never recommends a rollout decision; a site outside the OEM's stated validation envelope is flagged as unverified, not silently treated as covered, and every turbine's configuration record names its exact firmware revision and the date it was set.

VALIDATION MEASURES

Confirm on a pilot subset of turbines that the attestation record matches the actual installed firmware read from the controller, not just the deployment log, before trusting the record at fleet scale.

HUMAN DECISION

The asset owner's engineering authority approves the staged rollout sequence, including any sites held back pending further validation, and signs the configuration record at each stage.

DISCUSSION QUESTIONS

  1. What would it cost this fleet if the deployment log said a turbine was updated but the controller was not?
  2. Which sites sit outside the OEM's tested turbulence envelope, and what does 'unverified' mean for those specifically?
  3. Who has the authority to pause a rollout if early sites show an unexpected load signature?
