| # | step | agent | detail |
|---|---|---|---|
| 1 | INJECTION | Injection Engine | extreme_cold: ambient temperature -25°C (EXTREME — CW FREEZE IMMINENT). Duration ~18h. |
| 2 | MPC_SOLVE | MPC Optimizer | Cold front (EXTREME — CW FREEZE IMMINENT): CW supply at -20°C. CW FREEZE IMMINENT — ice formation in piping will block cooling flow. Antifreeze injection + heat-tracing on exposed headers required immediately. MAC air… |
| 3 | PHYSICS | Physics Kernel | Reducing load 100%→85% (actual cut 15 pts for EXTREME — CW FREEZE IMMINENT conditions). Cold: CW freeze risk is primary concern — trip would mean zero fill for 24h+. GOX/GAN/LOX/LIN rates drop ~15%. |
| 4 | PRODUCTION | Production Agent | Cold: lower ambient → lower boil-off (positive). BUT CW FREEZE will force trip → ZERO FILL. All tanks drain to customer demand only. LOX at 58%, LIN at 60%, LAR at 50%. |
| 5 | TANKS | Tank Inventory Agent | Cold: DANGEROUS road conditions — suspend non-P1 deliveries, driver safety paramount. Pre-position trucks at P1 hospitals. Emergency dispatch if plant trips. |
| 6 | DISPATCH | Dispatch Agent | SEVERE: 15-pt production cut for 18h — multiple customers at stockout risk. P1 hospitals need priority staging. At-risk tank count: 0. |
| 7 | CUSTOMERS | Customer Impact Agent | 📉 L1: Primary Production Physical Balance — PROC adjusts for thermal cycling stress on tank insulation |
| 8 | LOSS_MITIGATION | Loss Ledger | Load 100%→85% (15 pts): revenue impact -1087. Cold improves power efficiency slightly (+200k+ plus 24h outage — mitigation is cheap insurance. |
| 9 | ECONOMICS | Economics Agent | Weather-driven — no maintenance needed. 1) Monitor ambient temp trend. 2) CRITICAL: CW antifreeze injection NOW (target 30-40% glycol). Check every 30 min. Heat tracing amperage on exposed piping. 3) When ambient retu… |
| 10 | RECOVERY | Recovery Planner | Load=60% LOX=59% LIN=61% Surge=37% | INJ: Freeze -25°C, CW near freezing at NE-01, drain +0.60kg/s; extreme_cold: ambient temperature -25°C (EXTREME — CW FREEZE IMMINENT). Duration ~18h. |
| 11 | STEP_10 | STEP_10 | Active injection: extreme_cold — WEATHER: thermal stress → reduce to 60% |

Raw effects
- Freeze -25°C, CW near freezing at NE-01, drain +0.60kg/s
- extreme_cold: ambient temperature -25°C (EXTREME — CW FREEZE IMMINENT). Duration ~18h.
- Cold front (EXTREME — CW FREEZE IMMINENT): CW supply at -20°C. CW FREEZE IMMINENT — ice formation in piping will block cooling flow. Antifreeze injection + heat-tracing on exposed headers required immediately. MAC air density rises +2-3% (ρ/ρ₀ ≈ 293/(T+273)) → slightly higher mass flow, tighter surge margin.
- Reducing load 100%→85% (actual cut 15 pts for EXTREME — CW FREEZE IMMINENT conditions). Cold: CW freeze risk is primary concern — trip would mean zero fill for 24h+. GOX/GAN/LOX/LIN rates drop ~15%.
- Cold: lower ambient → lower boil-off (positive). BUT CW FREEZE will force trip → ZERO FILL. All tanks drain to customer demand only. LOX at 58%, LIN at 60%, LAR at 50%.
- Cold: DANGEROUS road conditions — suspend non-P1 deliveries, driver safety paramount. Pre-position trucks at P1 hospitals. Emergency dispatch if plant trips.
- SEVERE: 15-pt production cut for 18h — multiple customers at stockout risk. P1 hospitals need priority staging. At-risk tank count: 0.

- Load 100%→85% (15 pts): revenue impact -1087. Cold improves power efficiency slightly (+200k+ plus 24h outage — mitigation is cheap insurance.
- Weather-driven — no maintenance needed. 1) Monitor ambient temp trend. 2) CRITICAL: CW antifreeze injection NOW (target 30-40% glycol). Check every 30 min. Heat tracing amperage on exposed piping. 3) When ambient returns to 0-30°C range, ramp load back to 100%. 4) Expected recovery in 18h.
- Load=60% LOX=59% LIN=61% Surge=37% | INJ: Freeze -25°C, CW near freezing at NE-01, drain +0.60kg/s; extreme_cold: ambient temperature -25°C (EXTREME — CW FREEZE IMMINENT). Duration ~18h.
- Active injection: extreme_cold — WEATHER: thermal stress → reduce to 60%
