Status Note

• C01 and C02 — Closed. Client confirmed separate feeds and IIC mandated. Proceeding to update matrix and appendices.

1. Power supply topology — separate feeds vs chiller‑provided 1Φ

• Observation (evidence): Offer states “Client to provide 2 separate power supplies. 230V /1 phase for immersion heater. 3‑phase supply for Chiller unit.” (example-documentation-md/Q-32705 - Saipem COMP3/Q-32705-1 Priced Commercial Offer.md, lines 50–52). Tank DS lists 240V 1Φ for heater (lines 109–111). Chiller DS provides either 1Φ 220–240V or 3Φ 380–420V (lines 63–68).
• Decision: Accepted — Separate external feeds (230/240V 1Φ for heater; 3Φ for chiller) per offer.

2. Haz‑area gas group — IIC requirement for this package

• Observation (evidence): Tank DS indicates “ATEX Zone 1 & 2. Gas groups IIA & IIB. Temp Class T3 (IIC available)” (lines 105–111). EPC lighting specs/drawings include IIC occurrences for Ex fixtures (example-documentation-md/Q-32705 - Saipem COMP3/RFQ Files/200-91-EL-DWG-00032_B.md, e.g., lines 24305–24311).
• Decision: Accepted — IIC required for the package; configure IIC variants and supply matching certificates in Evidence Pack.
