CASE 01 / Fouling monitor dashboard

Root cause in an afternoon.

Cooling-water fouling on E-201, found and monitored.

Outlet temperature on E-201 drifts across three shifts, the trend reads as noise on a single chart, and the morning meeting keeps carrying it forward.

  1. 01
    Query the graph for what feeds and leaves E-201.
  2. 02
    Pull 72 hours of TI-201 and DP-201 into the sandbox.
  3. 03
    Execute change-point detection, which lands a break at 06:40 on day 3.
  4. 04
    Cross-check DP-201; ΔP rises in step with the temperature shift.
  5. 05
    Propose a fouling monitor: ΔT, ΔP, CW-IN, CW-OUT, fouling factor.

A live dashboard the crew keeps on the wall, wired to the same tags the operator already trusts.
