• Review equipment layouts, General Arrangement (GA) drawings, and Piping & Instrumentation Diagrams (P&IDs).


• Verify equipment nozzle orientation, load requirements, and interface details.


• Review equipment internals and associated mechanical components.


• Coordinate with stress analysis teams and other engineering disciplines to ensure design integrity.


• Review 3D models for P&ID consistency, layout compliance, constructability, and recommend design improvements.

Site Execution & Construction Support

• Control and monitor fabrication, installation, and erection activities of mechanical equipment in accordance with approved drawings, specifications, and contract requirements.


• Conduct site inspections, surveys, and field data collection to support engineering assessments and modifications.


• Identify and resolve technical issues, design discrepancies, and construction challenges, providing practical engineering solutions and recommendations.


• Prepare and issue site instructions in response to subcontractor technical queries.


• Ensure compliance with project quality, safety, and engineering requirements during execution activities.

Vendor & Package Engineering

• Review vendor documents, equipment data sheets, package drawings, and technical submissions.


• Coordinate technical clarifications and interfaces between vendors, contractors, and project teams.


• Participate in equipment inspections, technical evaluations, and vendor coordination meetings.


• Review manufacturing processes and ensure compliance with project specifications and applicable codes.

Documentation & Project Coordination

• Coordinate between Engineering Office and Site Office to resolve project-related issues.


• Review and manage the issuance of engineering deliverables and revisions.


• Review and verify final as-built drawings, layouts, and project documentation.


• Prepare SAP Purchase Requisitions (PR), material code creation, and OSRD spare parts reports.


• Supervise the preparation of conceptual layouts and coordinate interdisciplinary inputs through IDC (Inter-Discipline Coordination) documents.


• Develop equipment location plans in coordination with Mechanical, Electrical, Instrumentation, Civil/Structural, Process, Safety, and Project teams.

Key Requirements

• Bachelor's Degree (B.Tech/B.E.) in Mechanical Engineering or equivalent qualification.


• Minimum 10–15 years of experience in the Oil & Gas industry.


• Proven experience in mechanical engineering, field engineering, fabrication, installation, and commissioning of static and rotating equipment.


• Experience working on EPC, refinery, petrochemical, gas processing, LNG, or offshore/onshore oil & gas projects is highly desirable.
