Iraq GGIP: A Multi-Energy Piping and Water-System Project Reference

The project also includes the ArtawiGas25 early gas treatment unit to reduce flaring from end 2025. Commissioning is planned from 2025 to 2028, with a total investment of approximately $10 billion.

Piping and Water System Implications

GGIP involves extensive piping networks for gas, oil, and seawater. Key considerations for piping procurement include:

• Material Selection: For seawater service, corrosion-resistant alloys or lined carbon steel may be required. For gas and oil, carbon steel with appropriate coatings and cathodic protection is typical. Buyers must verify material grades based on project specifications, not assumptions.
• Standards Compliance: Piping components should meet ASME, API, or ISO standards as specified. For seawater, NACE MR0175 may apply for sour service. Always confirm with project documents.
• Sizing and Pressure Ratings: Line sizes and pressure classes vary by service. For high-pressure gas and oil, higher class flanges and fittings are needed. For seawater, large-diameter pipelines may require special handling.
• Corrosion Protection: External coatings, internal linings, and cathodic protection are critical for buried and subsea pipelines. Specify based on environmental conditions.

Procurement Checks for EPC Buyers

When sourcing piping components for projects like GGIP, consider the following:

• RFQ Inputs: Provide detailed line lists, service conditions, design codes, and material specifications. Include required standards (e.g., ASME B16.9 for fittings, ASME B16.5 for flanges) and any project-specific requirements.
• Supplier Qualification: Verify that suppliers have experience with similar projects and hold relevant certifications (e.g., ISO 9001, PED, API). Request references and audit if necessary.
• Quality Assurance: Require material test certificates (EN 10204 3.1 or 3.2) and third-party inspection if critical. Specify NDT methods (RT, UT, PT, MT) based on service.
• Logistics and Lead Times: For large-diameter or special alloy components, lead times can be long. Plan procurement early and consider local content requirements.

Inspection and Documentation Points

Inspectors should focus on:

• Dimensional Verification: Check dimensions against ASME B16.9, B16.5, or other applicable standards. Use calibrated tools and follow checklists.
• Material Verification: Perform PMI (Positive Material Identification) on alloy components to confirm composition.
• Weld Quality: For welded fittings, verify weld procedures and welder qualifications. Review NDT reports.
• Coating and Lining: Inspect for holidays, thickness, and adhesion. Ensure compliance with specifications.
• Documentation: Review MTCs, heat treatment charts, and NDT reports. Ensure traceability from mill to final product.

Common Risks and Mitigation

• Specification Gaps: Incomplete specifications can lead to wrong materials. Mitigate by using detailed RFQs and reviewing supplier proposals against project requirements.
• Counterfeit Materials: In high-value projects, risk of counterfeit fittings exists. Use authorized distributors and verify certificates.
• Corrosion Failures: In seawater service, improper material selection can cause rapid corrosion. Specify appropriate alloys and coatings.
• Schedule Delays: Long lead times for special items can delay construction. Order early and track progress.

Conclusion
