}Cascade — 10 agent steps
| # | step | agent | detail |
|---|---|---|---|
| 1 | INJECTION | Injection Engine | cooling_water_fouling: CW heat exchanger fouled. Supply temp rising to 34°C (design 26°C). MAC aftercooler less effective. |
| 2 | MPC_SOLVE | MPC Optimizer | 📐 MPC: Optimal load 83% (4h horizon) | Priority: 3 | Expected margin: $0/h | Reason: All constraints healthy → optimize revenue (+load) |
| 3 | PHYSICS | Physics Kernel | Fouled CW tubes reduce heat transfer coefficient. MAC discharge temp rises. Compressor efficiency drops as back-pressure increases. CW health at 75%. |
| 4 | PRODUCTION | Production Agent | Reducing 80%→75% to lower heat rejection load. At 75%, MAC power drops from 23MW to ~22MW. |
| 5 | TANKS | Tank Inventory Agent | Lower production → slower tank fill. LOX at 60%, LIN at 61%. Higher ambient heat also increases boiloff ~10%. |
| 6 | DISPATCH | Dispatch Agent | Normal dispatch continues. No emergency action needed unless CW temp exceeds 35°C (thermal runaway risk). |
| 7 | CUSTOMERS | Customer Impact Agent | Short-term impact minimal. Extended fouling (>12h) may affect customers with <3d inventory. |
| 8 | LOSS_MITIGATION | Loss Ledger | 📉 L1: Primary Production Physical Balance — SENS monitors CW temps to prevent excess boil-off losses |
| 9 | ECONOMICS | Economics Agent | CW fouling costs ~3-5k. ROI: cleaning pays for itself in <24h. |
| 10 | RECOVERY | Recovery Planner | 1) CW chemical cleaning crew dispatched. 2) Tube brushing + biocide treatment. 3) Duration 4-8h. 4) Post-clean: CW temp returns to 26°C design. |
