Role Purpose

Lead and manage all piping engineering activities for the offshore project across multiple offshore platforms at Umm Shaif Super Complex USSC. Ensure safe, compliant, and constructible piping design for instrument air, plant air, utilities, and compressor package integration, fully aligned with ADNOC Offshore standards.
The role involves close coordination with Engineering Subcontractors, Process, Mechanical, Electrical & I&C disciplines, OEMs, vendors, and ADNOC Offshore Operations throughout FEED, EPC, construction, and commissioning phases.

Piping Discipline Technical Authority

Act as the primary technical authority for all piping and layout engineering across the IA/PA upgrade works, ensuring compliance with:

ADNOC Piping Standards (ASME B31.3 / ADNOC CoPs / ADNOC offshore specifications)
Project-specific Design Basis & FEED intent
Offshore brownfield constraints
OEM piping interface requirements (compressor, dryer, receiver packages)
Class requirements for offshore structures
Provide guidance and approval across the full EPC piping scope.

Package Piping Integration & Vendor Coordination

Lead piping engineering for integrating the following packages:

Instrument Air Compressors
Plant Air Compressors
Twin Tower Air Dryers
IA/PA Air Receivers
Interconnecting skid piping (oil, air, condensate, drains)

Responsibilities include:

Reviewing vendor GA drawings, nozzle orientations, connection sizes & elevations
Ensuring correct mating flanges, material grades, pressure classes
Confirming nozzle loads, alignment and piping flexibility
Coordinating 3D model integration of OEM skids
Reviewing vendor hook-up drawings and utility tie-ins

Piping Material Engineering & Specifications

Oversee and validate:

Piping classes & MTO compliance (CS/SS/Instrument Air/Plant Air)
Pipe supports, clamps, spring hangers (where required)
Insulation & painting requirements
Pressure rating selection (Class 150/300 for IA/PA network)
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

Key Deliverables

Approved piping layouts, isometrics, and MTOs
Piping stress analysis and support design reports
Tie-in lists and brownfield modification packages
Vendor interface and piping integration reports
As-built piping drawings and documentation
Piping discipline inputs for commissioning and handover

Bachelor’s Degree in Mechanical / Piping Engineering
ADNOC Offshore approval or eligibility is mandatory
Chartered Engineer status or equivalent certification is an advantage

Minimum Experience: 15+ Years (Oil & Gas EPC Projects)
Offshore Experience: Mandatory (Brownfield Platform Projects Preferred)
