Lead Structural Design Engineer Ghobash Group

Lead and manage all structural engineering activities for the Offshore Project at Umm Shaif Super Complex USSC. The role ensures structural integrity, constructability, and compliance with ADNOC Offshore standards for new equipment installations, skids, pipe supports, and modifications on existing live offshore structures. The Lead Structural Engineer will coordinate with Engineering Subcontractors, OEMs, Marine teams, and ADNOC Offshore Engineering & Operations from FEED through EPC, installation, and commissioning.

Serve as the primary authority for all structural engineering activities related to IA/PA upgrades, ensuring adherence to:

• ADNOC Structural Engineering Standards
• ISO, API RP2A, AISC, BS, and offshore structural codes
• ADNOC offshore brownfield requirements
• Project Basis of Design and FEED integrity
• Structural integrity and safety requirements for all package equipment
• Provide clear oversight and final approval on structural discipline matters

Lead structural engineering governance for integrating:

• Instrument Air Compressors
• Plant Air Compressors
• Twin Tower Dryers
• IA/PA Air Receivers
• Associated skid structures and platforms
• Lifting frames, base frames, and support steel

Responsibilities:

• Verify skid loading, static & dynamic reactions
• Check structural adequacy of supporting platforms
• Validate vendor structural information (CG, weights, loads)
• Review equipment baseplates, foundation pad/skid supports
• Ensure offshore environmental load conditions are considered
• Approve structural reinforcement requirements

Brownfield engineering is critical for ADNOC platforms.

Lead structural tasks include:

• Assessing existing deck load capacity
• Reviewing as-built drawings, laser scans, & survey data
• Identifying reinforcement needs for increased loads
• Checking space constraints & structural conflicts
• Ensuring safe access & maintenance clearance
• Reviewing EPC brownfield method statements
• Verifying tie-in locations for new supports and routing
• Confirming deck rating suitability for compressors/dryers
• Support safe brownfield execution under SIMOPS and offshore constraints.

Review EPC contractor structural analyses:

• Global & local FEA (Finite Element Analysis)
• Deck load & punching shear checks
• Fatigue analysis (if applicable)
• Vibration assessments for rotating equipment
• Impact load/accidental load checks
• Dynamic load & equipment vibration transmission
• Wind, wave & seismic load evaluation for offshore
• Ensure all structural calculations meet ADNOC safety factors and design criteria.

Lead 3D model structural validation for:

• Equipment placement & support framing
• Clearances, access, and maintenance envelopes
• Structural element clashes with piping/E&I/trays
• Cable tray and piping penetrations
• Location and routing of additional supports
• Structural stability & stiffness checks
• Participate in 30% / 60% / 90% EPC model review sessions.

Proficient in AVEVA (E3D/PDMS) and SP3D for structural modelling, steel framing and platform design, clash detection, and extraction of structural GA drawings, fabrication details, IFC and MTO deliverables in accordance with ADNOC design standards.

Experienced with SACS, STAAD. Ro, Tekla Structures, AutoCAD, Navisworks, AVEVA E3D and SP3D for offshore structural analysis, 3D modelling, detailing, and preparation of IFC/MTO deliverables as required for ADNOC projects.

Provide structural OE oversight for installation engineering:

• Review lifting plans & rigging studies
• Validate crane capacity, rigging points, padeyes
• Review temporary lifting frames or lifting lugs
• Ensure compliance with offshore lifting standards
• Verify transport & installation load conditions
• Support safe mechanical installation offshore.

Provide structural input for:

• HAZID, HAZOP (structural interface actions), SIMOPS reviews, ENVID,
• Fire Protection & Blast Loading (if applicable)
• Ensure structural integrity is maintained during all phases of EPC.

Review and approve:

• Structural drawings (GAs, details, reinforcements)
• Fabrication drawings
• Welding maps, WPS/PQR/NDE requirements
• Structural MTOs
• Tie-in support drawings
• Offshore installation plans
• Structural demolition & modification drawings
• Ensure alignment with ADNOC formats and numbering.

Provide OE-level assurance during structural fabrication:

• Review EPC QCP/ITP for structural fabrication
• Validate material traceability and weld quality
• Review NDT plans (UT, RT, MT, PT)
• Monitor fabrication progress (if required)
• Approve structural works before delivery offshore

During field execution, support:

• Structural element installation guidance
• Field modifications and clash resolution
• Punch-list preparation and closure
• Verification of structural stability after installation
• As-built validation & final acceptance

Maintain structural discipline registers (load sheets, analyses, GA tracking)

• Review weekly EPC progress and structural updates
• Track TQs, deviations, NCRs & change requests
• Ensure full compliance with ADNOC document control requirements
• Verify final as-built structural documentation

Key Deliverables

• Structural design calculations and assessment reports
• Equipment foundation and modification drawings
• Lifting and installation support documents
• As-built structural drawings and records
