Ghobash Group

Role Purpose

Lead all mechanical, piping and structural engineering activities for the IA/PA Upgrade Project.

The engineer ensures complete design integration, technical compliance, and constructability across multiple platforms, coordinating with Engineering Subcontractor, Vendors / OEMs, and ADNOC Offshore teams from concept to installation.

Key Responsibilities (Project Specific)

Mechanical Engineering

• Review design and vendor data for compressor packages, air dryers, receivers and auxiliary skids.
• Verify mechanical interfaces, utility connections, alignment and foundation requirements.
• Evaluate package GAs, datasheets, and P&IDs to ensure consistency with process requirements.
• Check lifting, handling and transport arrangements in accordance with ADNOC Offshore rules.
• Coordinate FAT / SAT activities with OEMs (Compressor, Dryer & Receiver suppliers).

Piping Design & Layout

• Lead routing of IA and PA headers within existing deck space
• Develop tie-in strategies to existing headers with minimum shutdown and production impact.
• Review isometrics, support layouts, valve lists and material specifications.
• Review stress analysis and ensure adequate flexibility and supports.
• Coordinate with Process and Electrical teams for interface locations and routing constraints.

Structural Engineering & Deck Integration

• Assess existing deck capacity for new equipment installation.
• Conduct structural analysis / strength checks for compressor and receiver foundations.
• Design steel supports, pipe racks, platform extensions (if any), and equipment frames.
• Review lifting plans, deck load maps and erection schemes to ensure safety and stability.
• Coordinate with ADNOC Offshore Civil/Structural for approval of load changes and lifting arrangements.

Coordination with Engineering Subcontractor

• Act as the primary focal point for all mechanical, piping and structural deliverables.
• Review and approve subcontractor drawings, models and calculations.
• Ensure timely submission of Section 6 deliverables and compliance with ADNOC Offshore standards.
• Conduct inter-discipline reviews to resolve layout and interface issues early.

Vendor / OEM Coordination (High Priority)

• Liaise with OEMs for compressor packages, dryers, receivers, and skid suppliers.
• Review vendor data for mechanical loads, nozzle orientation, pipe size and instrument interface.
• Ensure vendor equipment fits within available space and connects to existing utilities.
• Participate in FAT / SAT and resolve technical queries during manufacture and installation.

Construction & Installation Support

• Prepare and review method statements for equipment installation, piping tie-ins, and lifting.
• Support construction team for site measurements and as-built verification.
• Attend offshore site visits to resolve interface and installation issues.
• Verify alignment, fit-up and erection tolerances during installation.
• Ensure PTW and SIMOPS procedures are followed for brownfield works.

Interface & Integration Management

• Coordinate with Process, Electrical and I&C engineers for equipment interfaces and tie-ins.
• Maintain mechanical interface register and ensure alignment with ADNOC Offshore projects (LTDP-1, Load Migration).
• Support interface meetings with ADNOC and resolve clashes proactively.

Key Deliverables

• Mechanical / Piping / Structural drawings and layouts.
• Equipment foundation and support designs.
• Piping tie-in layouts and isometrics.
• Structural load check reports and lifting plans.
• Vendor data review and approval records.
• Installation method statements and as-built documentation.
• Interface register updates and meeting minutes.
