Lead Piping Engineer

Role PurposeLead 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 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)ResponsibilitiesReviewing 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 HAZOPEN VIDSIMOPS 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 feasibilityParticipate in FAT/SAT for piping-related skid components where needed.Construction & Commissioning SupportProvide OE piping oversight to ensure safe and correct installation:Assist EPC during offshore piping prefabrication and installationValidate pipe support installation & alignmentReview hydrotests packages charts and reinstatement recordsVerify line flushing/blowing readinessProvide final piping acceptance for Mechanical Completion (A/B/C punch items)Support IA/PA network pressurization and leak testingDocumentation Deliverables & ReportingReview and approve EPC piping deliverables (P&IDs GAs Isos MTOs)Ensure strict compliance with ADNOC numbering systemsMaintain discipline comment registers TQ log
