Deviation Report (Draft) — Q-32859

Client_Profile: ADNOC

Deviation Candidates (link to Matrix Req_ID)

• Deviation_ID: D-001

  • 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, lines 1385–1387)
  • Offered Provision (quote + page/line): Chiller classification Zone‑1 IIB T3 (Chiller Datasheet lines 103–105). Tank shower base IIA/IIB T3 (IIC available) (Datasheet lines 105–111).
  • Technical Justification: System meets minimum IIB T3; for H₂ service, IIC T3 is commonly required. We can supply IIC variants; request client confirmation (RFI #1). If IIC required, selection update has no performance impact.
  • Impact: None to performance; minor to cost/lead depending on certification variant.
  • Proposed Client Wording: “Confirm whether IIC T3 classification is required for all units in H₂ service. If confirmed, supplier will provide IIC‑certified components across the assembly.”
  • CPQ Implication: Select IIC options for electrics/instruments and chiller variant if required.

• Deviation_ID: D-002

  • Req_ID: R-0003 (Elec)
  • Client Requirement: Power distribution alignment per site; details to be confirmed in MR Elec section (pending extraction).
  • Offered Provision: Chiller power 415 VAC 3Φ with 230 VAC 1Φ feed to shower (Offer p.4, lines 364–366). Shower datasheet indicates 240 V 1Φ heater (lines 109–113).
  • Technical Justification: Standard topology minimizes external feeds; aligns with packaged system practice.
  • Impact: None to performance; installation planning for single external 3Φ feed.
  • Proposed Client Wording: “Confirm acceptance of chiller‑provided 230 VAC feed to the shower immersion heater and light, with a single external 415 VAC 3Φ feed to the chiller.”
  • CPQ Implication: None; topology confirmation only.

• Deviation_ID: D-003 (Operator Review)

  • Req_ID: R-0008 (IP)
  • Client Requirement (verbatim + source): “All field instruments shall be protected to IP 65 as a minimum…” (RLNG-000-IC-SP-0801 §7.4.13, lines 9220–9224)
  • Offered Provision (quote + line): Chiller Datasheet indicates IP65 for instruments and IP55 for pump motor (lines 116–117).
  • Technical Justification: The IP65 minimum explicitly applies to field instruments and enclosures; pump motor IP may be governed by rotating equipment standards and service conditions. If client interprets IP65 to apply to motors, propose motor upgrade or justification that IP55 is acceptable for the installed environment.
  • Impact: Potential cost/lead impact if IP upgrade required; no functional change anticipated.
  • Proposed Client Wording: “Confirm whether IP65 minimum applies to pump motors; if so, supplier to propose compliant motor or confirm acceptance of IP55 per service and protection provisions.”
  • CPQ Implication: If upgrade required, change motor option on chiller package.

Notes

• Upon acceptance, Appendix 2 will be auto‑populated from these entries; operator will review before external sharing.
