• Deviation_ID: D-001

  • Project: Q-32859 (NMDC Energy — Ruwais LNG) | Client_Profile: ADNOC
  • Req_ID: R-0001 (HazArea)
  • Client Requirement (verbatim + source): “Even in non-hazardous area, all instrument components shall be designed for Zone1 Gas group IIB and ignition Temperature class T3 as per IEC 60079, as a minimum requirement.” (MR RLNG-000-HS-R-8851 §12.2)
  • Offered/Decision: Configure H₂ units as IIC T3 end‑to‑end. Tank shower IIC variant available (Datasheet with GAD - Safety Shower EXP-MH-14KS-1500.md, lines 105–111). Chiller offered Zone‑1 IIB T3; matching IIC certification to be provided in submittals (Q-32859 Chiller Datasheet.md, lines 103–105).
  • Rationale: Aligns with ADNOC baseline for H₂ (Client_Profile_Baselines.md). No performance impact; certification variant selection only.
  • CPQ Implication: Select IIC-certified components across assembly where H₂ service applies.

• Deviation_ID: D-002

  • Project: Q-32859 (NMDC Energy — Ruwais LNG) | Client_Profile: ADNOC
  • Req_ID: R-0003 (Elec/Power Topology)
  • Client Requirement: Site power alignment (MR Elec section; topology confirmation)
  • Offered/Decision: Single external 415 VAC 3Φ feed to chiller; 230/240 VAC 1Φ feed from chiller to shower heater/light (Q-32859-1.md p.4 lines 364–366; Datasheet with GAD - Safety Shower EXP-MH-14KS-1500.md lines 109–113).
  • Rationale: Minimizes external interfaces; standard packaged practice.
  • CPQ Implication: None (topology confirmation only).
