- Pigging and flushing requirements (if applicable)
- Material substitution proposals from EPC
Brownfield Integration & Tie-In Engineering
Lead piping design for brownfield connections across multiple platforms:
- Identify and verify tie-in points on existing IA/PA networks
- Validate routing feasibility in congested areas
- Review site survey data laser scans and field measurements
- Ensure safe access & maintenance clearance for new routing
- Review EPC brownfield method statements (hot work prefab cold work)
- Evaluate need for temporary IA/PA bypass lines during shutdown
- Produce piping risk register for brownfield modifications.
3D Model Governance & Multi-Discipline Integration
Lead piping model reviews for:
- Compressor area layout
- Dryer skid placement
- Receiver positioning and supports
- Routing optimization to avoid clashes
- Access operability and maintainability checks
- Escape route & safety distance compliance
- Conduct structured 3D model review sessions (30% / 60% / 90%) with EPC OEM ADNOC PMC & Ops.
- Proficient in AVEVA (E3D/PDMS) and SP3D for advanced piping design 3D modelling routing clash detection pipe support integration and extraction of isometrics GA drawings IFC and MTO deliverables in alignment with ADNOC design standards.
Piping Stress Engineering Oversight
Review and approve stress analysis for:
- Compressor suction/discharge piping
- Dryer inlet/outlet lines
- Receiver-to-header connections
- Large-bore pipe stress and support adequacy
- Thermal expansion cases
- Vendor nozzle load limitations
- Validate EPC stress reports and compliance with ASME/API standards.
HSE Safety and Integrity Compliance
Provide piping discipline input for:
- HAZID HAZOP ENVID SIMOPS reviews SIL/LOPA (piping-related failures and safeguards)
- Escape route and congested area analysis
- Ensure piping meets fireproofing hazardous area and process safety requirements.
Coordination with EPC OEMs & Other Disciplines
Daily coordination with:
- EPC Piping Mechanical Structural Electrical and I&C teams
- Compressor and Dryer OEM Engineers
- ADNOC Ops & PMT 3rd-party survey teams
Review and comment on EPCs:
- Piping GAs Isometrics Support drawings Tie-in packages MTOs TQs and deviations
- Ensure timely closure of comments.
QA/QC Oversight for Piping Discipline
Check EPC compliance with:
- QCP/ITP requirements for welding NDT hydrotesting
- Piping fabrication drawings
- Spool numbering fit-up and prefabrication quality
- Offshore lifting assembly and installation feasibility
- Participate in FAT/SAT for piping-related skid components where needed.
Construction & Commissioning Support
Provide OE piping oversight to ensure safe and correct installation:
- Assist EPC during offshore piping prefabrication and installation
- Validate pipe support installation & alignment
- Review hydrotests packages charts and reinstatement records
- Verify line flushing/blowing readiness
- Provide final piping acceptance for Mechanical Completion (A/B/C punch items)
- Support IA/PA network pressurization and leak testing
Documentation Deliverables & Reporting
- Review and approve EPC piping deliverables (P&IDs GAs Isos MTOs)
- Ensure strict compliance with ADNOC numbering systems
- Maintain discipline comment registers TQ logs & interface registers
- Validate as-built piping documents post commissioning
- Provide weekly piping discipline reports to OE Engineering Manager
