• Develop and review P&IDs, GA drawings, 3D models, piping layouts, support drawings, datasheets and equipment specs.
• Ensure all mechanical systems meet relevant codes and standards (ASME, IS, API, PED, TEMA, ISO 22734 etc.).
• Oversee stress analysis, pipe thickness calculations, and pressure part design.
• Ensure adequate provisions for safety, maintainability, and operability in the design.
• Interface with process, electrical, instrumentation, and civil teams to align mechanical scope.

3. Procurement & Vendor Management

• Prepare and review technical specifications, datasheets, and tender documents for mechanical equipment.
• Participate in vendor selection, techno-commercial evaluations, and finalization.
• Review and approve vendor drawings, QAPs, and manufacturing plans.
• Conduct vendor shop visits, inspections, and FATS to ensure quality and conformity

• 4. Manufacturing Review

• Oversee and guide equipment manufacturing and fabrication activities for electrolyser and mechanical systems.
• Review and approve welding procedures, NDT plans, hydrotest protocols, and fabrication workflows.
• Ensure timely manufacturing and delivery in alignment with project schedules.
• Coordinate with QA/QC and project teams for issue resolution and compliance.
• 5.Site Execution & Commissioning

• Provide technical support during mechanical erection, pre-commissioning, and commissioning stages.
• Lead the mechanical commissioning, flushing, testing, and performance validation of electrolyser and BoP systems.
• Support installation of pipelines, compressors, dryers, storage tanks, and cooling water systems.
• Ensure HSE compliance and adherence to quality protocols at site.
• Operations Support

• Provide handover support to O&M teams including documentation, O&M manuals, troubleshooting guidance, and training.
• Participate in root cause analysis, performance monitoring, and optimization activities.
• Suggest improvements for reliability, availability, and maintenance practices of mechanical systems.

Required Skills and Competencies:

• Strong understanding of mechanical systems in process/chemical/H2 plants.
• Proven experience in EPC project execution from engineering to commissioning.
• Proficient in piping, pressure vessels, rotating equipment, skids, and structural design.
• Familiarity with standards: ASME, API, TEMA, IS, PED, BIS, OISD.
• Experience in 3D modeling (AutoCAD, SolidWorks, PDMS, E3D, or similar).
• Knowledge of fabrication, inspection, and welding practices.
• Strong interpersonal and leadership skills; ability to coordinate across multiple teams and vendors.
• Excellent documentation, reporting, and presentation skills.
