Position Overview
The Sealine Engineer in Abu Dhabi is a specialist subsea pipeline engineering role within the oil and gas sector — covering the complete technical lifecycle of sealine design, installation analysis, and project engineering from initial concept and technical proposals through design verification, installation method definition, subcontractor engineering review, and procurement support. You will apply advanced pipeline engineering knowledge — spanning stress and expansion analysis, riser design, pipeline on-bottom stability, hydrodynamic loading, and installation load cases — to deliver technically sound sealine engineering solutions for EPCI and T&I contracts in Abu Dhabi’s active offshore oil and gas development environment.
This role demands a pipeline engineer with both the technical depth to perform and supervise complex sealine design analyses independently and the project engineering capability to manage deliverables, coordinate with subcontractors and clients, contribute to bid evaluations, and ensure that all engineering documentation meets the quality standards required for major offshore oil and gas contracts in Abu Dhabi. Proficiency in pipeline design software and finite element analysis tools, combined with a thorough working knowledge of DNVGL, ASME, API, and ISO subsea pipeline standards, are essential to performing this role at the level Abu Dhabi’s oil and gas sector demands.
Why Sealine Engineers Are Critically Important in Abu Dhabi in 2026: Abu Dhabi’s offshore oil and gas infrastructure — spanning ADNOC’s vast network of subsea pipelines, gathering systems, and export sealines connecting offshore platforms, artificial islands, and onshore terminals — represents one of the world’s largest and most technically demanding subsea pipeline systems. Every new field development, capacity expansion, and pipeline replacement programme requires sealine engineers who can design and verify pipelines that will operate safely at pressure, temperature, and in the marine environment of the Arabian Gulf for 25–30 year design lives. In Abu Dhabi, that technical expertise is not merely valued — it is operationally essential to the hydrocarbon production that funds the entire national development agenda.
Key Responsibilities
Sealine Design & Installation Analysis
- Perform and/or supervise sealine design and installation analysis — applying subsea pipeline engineering expertise to design sealines that meet the structural, operational, and environmental requirements of Abu Dhabi’s offshore oil and gas developments, and to analyse installation load cases, on-bottom stability, span assessment, and free-span mitigation for pipelines being installed by S-lay, J-lay, reel-lay, or other offshore installation methods
- Perform stress and expansion analysis — conducting thermal expansion, pressure-induced expansion, Poisson contraction, and combined load case analyses for subsea pipelines and risers, applying finite element analysis tools and industry-standard pipeline analysis software to verify that sealine stresses, displacements, and end movements comply with DNVGL, ASME, and applicable project code requirements throughout all operational and installation load cases
- Apply expertise in riser design and subsea structures — engineering the pipeline-to-platform interface, including riser stress analysis, riser clamp spacing, riser guide configurations, and the structural interface between the subsea pipeline system and offshore topside or subsea structure connections
- Assess and design for pipeline on-bottom stability and hydrodynamic loading — applying Arabian Gulf environmental data, seabed sediment characteristics, and pipeline geometry to verify that sealines remain on-bottom stable under design wave and current conditions throughout their service life, and specifying concrete weight coating, rock dumping, or other stabilisation measures where required
Technical Documentation & Project Engineering
- Prepare technical reports, drawings, specifications, and requisitions — producing the complete set of engineering deliverables required for sealine design packages, installation engineering submissions, material requisitions, and project documentation in accordance with the quality management system and document control requirements applicable to Abu Dhabi oil and gas contracts
- Define operational installation methods and limits — establishing the limiting environmental conditions (wave height, current, wind, vessel motion) and operational parameters within which offshore sealine installation can be safely and compliantly performed, based on installation analysis results, vessel capability assessments, and applicable regulatory requirements
- Ensure project documentation meets applicable quality standards — reviewing and verifying the technical quality, completeness, and compliance of all sealine engineering documents before issue, ensuring that all deliverables meet the technical specification, quality management, and document control requirements of the EPCI or T&I contract
- Support continuous improvement of engineering processes, tools, and procedures — contributing technical knowledge and project experience to the ongoing development and refinement of the organisation’s sealine engineering methodologies, software tools, design procedures, and technical standards
Subcontractor Engineering, Bid Evaluation & Procurement
- Verify subcontracted engineering and oversee procurement/bid evaluation — reviewing and technically approving engineering submissions from pipeline design subcontractors, material suppliers, and specialist engineering service providers, assessing the technical compliance and adequacy of their deliverables against project specifications and applicable subsea pipeline design standards
- Review client requirements and contribute to technical proposals for EPCI and T&I contracts — applying sealine engineering expertise to the preparation and review of technical proposals for Engineering, Procurement, Construction, and Installation or Transportation and Installation contracts, including basis of design documentation, technical approach descriptions, and preliminary design analyses that demonstrate the organisation’s technical capability to prospective clients
- Prepare and review technical specifications, perform bid evaluations, and manage engineering deliverables — developing the technical content of material and service requisitions, evaluating supplier and subcontractor bid submissions against technical requirements, and managing the engineering deliverables schedule to ensure all project documentation milestones are met
