Lead Piping Design Engineer [Offshore Project]

Company DescriptionEmirates Electrical & Instrumentation Company LLC is a proud member of the Ghobash Group. For almost 20 years, we have made vital contributions to the Oil & Gas sector of the UAE, executing both onshore and offshore projects. Abu Dhabi National Oil Company (ADNOC) is one of our main clients along with Tier 1 and Tier 2 EPC contractors in this sector. We have the expertise to carry out full EPC&M services for electrical and instrumentation works and bring our intrinsic knowledge to measure and automate exploration, production, separation, refining processes, and distribution through our localized services.Job DescriptionRole PurposeLead and manage all piping engineering activities for the IA/PA Upgrade 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 AuthorityAct 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 intentOffshore brownfield constraintsOEM piping interface requirements (compressor, dryer, receiver packages)Class requirements for offshore structuresProvide guidance and approval across the full EPC piping scope.Package Piping Integration & Vendor CoordinationLead piping engineering for integrating the following packages:Instrument Air CompressorsPlant Air CompressorsTwin Tower Air DryersIA/PA Air ReceiversInterconnecting skid piping (oil, air, condensate, drains)Responsibilities include:Reviewing vendor GA drawings, nozzle orientations, connection sizes & elevationsEnsuring correct mating flanges, material grades, pressure classesConfirming nozzle loads, alignment and piping flexibilityCoordinating 3D model integration of OEM skidsReviewing vendor hook-up drawings and utility tie-insPiping Material Engineering & SpecificationsOversee and validate:Piping classes & MTO compliance (CS/SS/Instrument Air/Plant Air)Pipe supports, clamps, spring hangers (where required)Insulation & painting requirementsPressure rating selection (Class 150/300 for IA/PA network)Pigging and flushing requirements (if applicable)Material substitution proposals from EPCBrownfield Integration & Tie-In EngineeringLead piping design for brownfield connections across multiple platforms:Identify and verify tie-in points on existing IA/PA networksValidate routing feasibility in congested areasReview site survey data, laser scans, and field measurementsEnsure safe access & maintenance clearance for new routingReview EPC brownfield method statements (hot work, prefab, cold work)Evaluate need for temporary IA/PA bypass lines during shutdownProduce piping risk register for brownfield modifications.3D Model Governance & Multi-Discipline IntegrationLead piping model reviews for:Compressor area layoutDryer skid placementReceiver positioning and supportsRouting optimization to avoid clashesAccess, operability and maintainability checksEscape route & safety distance complianceConduct 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 OversightReview and approve stress analysis for:Compressor suction/discharge pipingDryer inlet/outlet linesReceiver-to-header connectionsLarge-bore pipe stress and support adequacyThermal expansion casesVendor nozzle load limitationsValidate EPC stress reports and compliance with ASME/API standards.HSE, Safety, and Integrity ComplianceProvide piping discipline input for:HAZID, HAZOP, ENVID, SIMOPS reviews, SIL/LOPA (piping-related failures and safeguards)Escape route and congested area analysisEnsure piping meets fireproofing, hazardous area, and process safety requirements.Coordination with EPC, OEMs & Other DisciplinesDaily coordination with:EPC Piping, Mechanical, Structural, Electrical, and I&C teamsCompressor and Dryer OEM EngineersADNOC Ops & PMT, 3rd-party survey teamsReview and comment on EPCs:Piping GAs, Isometrics, Support drawings, Tie-in packages, MTOs, TQs and deviationsEnsure timely closure of comments.QA/QC Oversight for Piping DisciplineCheck EPC compliance with:QCP/ITP requirements for welding, NDT, hydrotestingPiping fabrication drawingsSpool numbering, fit-up, and prefabrication qualityOffshore lifting, assembly, and installation fe
