Mechanical Commissioning Lead

Overview

NAES is seeking a Mechanical Commissioning Lead to support mechanical system commissioning and turnover activities for a project in Tennessee. This role will serve as the system owner for mechanical BOP equipment, overseeing all system readiness activities including walkdowns, mechanical completion verification, flushing/blowdown activities, equipment testing, and turnover package documentation. The Mechanical Commissioning Lead works closely with construction, electrical, I&C, and startup teams to ensure safe, accurate, and efficient system transition from construction to operations.

• Mechanical commissioning experience on combined-cycle power projects required
• Strong Balance of Plant (BOP) system expertise (fuel gas, lube oil, cooling water, air systems, pumps, tanks, piping, and steam-side auxiliary systems)
• Experience performing mechanical walkdowns, system verification, flushing/blowing, and turnover documentation
• Ability to coordinate with construction, electrical, I&C, and DCS teams during system checkout and startup

• Lead the mechanical commissioning activities for BOP and auxiliary systems including fuel gas, lube oil, cooling water, air systems, pumps, tanks, piping, and HRSG and steam-related mechanical systems
• Perform and oversee system walkdowns, verify system completeness, and generate/resolve punchlist items
• Coordinate flushing, blowing, pressure testing, leak checks, valve lineups, rotation checks, lubrication readiness, and equipment testing
• Support mechanical system turnovers including redlines, mechanical completion forms, and system documentation updates
• Collaborate with I&C and DCS teams to verify mechanical interlocks, per missives, feedback signals, and alarm logic related to mechanical systems
• Participate in daily commissioning and startup coordination meetings with EPC, owner’s representatives, and operations teams
• Review P&IDs, vendor manuals, system boundaries, and engineering packages to ensure mechanical systems meet design and commissioning requirements
• Troubleshoot mechanical issues impacting system readiness, equipment performance, or startup sequencing
• Ensure mechanical commissioning work is executed safely and in compliance with site procedures, LOTO policies, and EPC protocols

• Strong understanding of mechanical commissioning processes for power generation or EPC projects
• Ability to interpret P&IDs, system drawings, isometrics, vendor documentation, and mechanical turnover packages
• Hands-on experience performing mechanical testing (flushing, leak testing, vibration checks, alignment, lubrication system verification)
• Experience working with EPC punchlist systems, turnover documentation, and structured commissioning workflows
• Ability to coordinate across multiple disciplines including construction, electrical, I&C, and startup operations
• Strong problem-solving skills and ability to troubleshoot pumps, rotating equipment, valves, and mechanical BOP systems

• 7+ years of mechanical commissioning experience on power generation or industrial EPC projects
• Prior work on GE 7HA, advanced-class combined cycle units, or large gas turbine BOP systems strongly preferred
