• Define systemization and subsystem boundaries (MC to RFC to RFSU).
• Review commissioning work packs and procedures.
• Develop Commissioning and Start-up procedures
• Develop/Review Method statements, JSA's as required
• Interface with procurement to purchase spares, consumables, tools and equipment.
• Establish equipment preservation and reinstatement strategy.
• Coordinate Mechanical Completion (MC) certification with construction team.

Interface & Leadership

• Lead mechanical commissioning team and supervisors
• Interface with Construction manager, QAQC, Process Commissioning Lead, E&I commissioning team, Vendor Representatives, Operations Teams
• Coordinate vendor site activities
• Report progress, risk, and technical issues to Commissioning Manager

Mechanical Equipment Commissioning

Static Equipment

• Verify installation of separators, heater treaters, pressure vessels, tanks, and heat exchangers.
• Witness internal inspections and box-up activities.
• Ensure correct torqueing, gasket installation, and flange integrity.
• Confirm alignment, grouting, and structural integrity.
• Review hydrotest and leak test records.
• Validate installation of safety relief devices.

Rotating Equipment

• Supervise alignment verification (laser alignment).
• Oversee lube oil flushing and cleanliness verification.
• Witness vibration testing and establish baseline readings.
• Review and implement vendor commissioning procedures.
• Lead no-load and load testing activities.
• Monitor mechanical seals and dry gas seal readiness.

Piping Systems Commissioning

• Review isometric drawings and test packs.
• Ensure hydrotesting, pneumatic testing, and proper reinstatement.
• Supervise chemical cleaning, flushing, pigging, and air blowing.
• Validate line walkdowns against P&IDs.
• Verify torqueing, tensioning, supports, and expansion joints.
• Manage punch list clearance (A/B/C categories).

Startup & Operational Readiness

• Mechanical completion verification
• Line checks and valve verification
• Internal cleanliness inspections
• Witness bolt torque checks
• Verify supports, spring hangers, and expansion joints
• Ensure insulation and painting completion (as required before startup)

Key HSE Responsibilities

• Ensure compliance with API 610, API 617, API 650, ASME Section VIII, ASME B31.3, and project HSE requirements.
• Lead risk assessments for hydrotesting, pneumatic testing, flushing, pigging, lifting operations, and equipment energization.
• Ensure proper certification and reinstatement of pressure systems prior to startup.
• Verify safe execution of confined space entry, hot work, heavy lifting, and high-pressure testing activities.
• Validate installation and testing of safety relief valves, isolation systems, and emergency depressurization facilities.
• Ensure mechanical integrity of rotating equipment including alignment, vibration limits, and protection systems prior to operation.
• Enforce Permit-to-Work (PTW) and Lock-Out/Tag-Out (LOTO) procedures during commissioning activities.
• Investigate mechanical failures, leaks, or safety incidents, ensuring root cause analysis and corrective actions are implemented.
• Promote proactive hazard identification and strong safety culture within mechanical and piping teams.
• Participate in HAZOP close-outs and Pre-Startup Safety Reviews (PSSR).
