• Ensure system design meets project requirements, offshore environmental conditions, and classification society rules.
• Review mechanical data sheets, P&IDs, air balance studies, and technical specifications.
• Participate in engineering coordination meetings and interface with other disciplines (mechanical, electrical, instrumentation, structural, HSE).

Vendor Engineering & Quality Control

• Review vendor documents including equipment GA drawings, ITPs, QA/QC plans, material specifications, test procedures and installation manuals.
• Verify compliance of vendor design and manufacturing with project standards, international codes (ISO, ASHRAE, API, ABS)
• Conduct or participate in vendor shop inspections, FAT, performance testing, and manufacturing quality audits.
• Manage NCRs, ensure timely root-cause analysis and corrective actions by vendors, and verify closure.
• Support procurement team in technical evaluation (TBE) and bid clarification.

Project Execution & Coordination

• Support detailed engineering phases being executed by partners/contractors on large offshore packages
• Participate in construction readiness reviews, installation support, and commissioning planning.
• Coordinate with offshore site teams to address HVAC issues during construction and start-up.
• Support development and implementation of HVAC‑related quality traceability and documentation systems.

D. Documentation & Compliance

• Ensure all HVAC engineering documents meet EPC and Client requirements
• Prepare engineering reports, design calculations, inspection records and final as-built documentation packages.
• Maintain accurate records for procurement, fabrication, and commissioning deliverables.

3. Qualifications & Experience

Education

• Bachelor’s degree in Mechanical Engineering.
• Preferred: Postgraduate studies in HVAC, Thermo-Fluids, or Building Services.
• Nice to have: Certified HVAC Engineer / ASHRAE membership / Offshore survival certificates.

Experience (10–15 years)

• Strong experience in HVAC design and engineering for offshore oil & gas platforms, FPSOs, or large industrial facilities.
• Proven track record in vendor engineering management and quality control for HVAC equipment (AHUs, FCUs, chillers, compressors, ventilation systems).
• Experience with EPCI projects, preferably involving offshore processing platforms, utility modules or LQ modules.
• Familiarity with Middle East offshore project requirements is advantageous

Technical Skills

• HVAC design tools (HAP, Carrier, CHVAC, AutoCAD, AVEVA, etc.)
• Strong understanding of offshore HVAC codes: ASHRAE, ISO, IECEx/ATEX for hazardous areas.
• Experience reviewing ITPs, FAT procedures, QA/QC documents and vendor data packages.
