Full Job Description

Position Summary
We are seeking a Senior Mechanical Commissioning Engineer with deep, hands-on experience commissioning LNG liquefaction trains, including rotating equipment packages centered on Baker Hughes Frame 7 gas turbines driving Mixed Refrigerant (MR) and Propane Refrigeration (PR) compression systems. This role will lead mechanical commissioning planning and execution from pre-commissioning through start-up and performance testing, ensuring safe, compliant, and reliable turnover to Operations.
Key Responsibilities

Lead mechanical commissioning execution for LNG liquefaction trains from system completion through start-up and stabilization.
Develop and execute commissioning deliverables: commissioning procedures, check sheets, readiness plans, punch management, turnover dossiers, and system handover packages.
Provide technical leadership for rotating equipment commissioning, including:
Frame 7 turbine-driven compression trains
MR and PR compressor packages
Auxiliaries (seal systems, lube oil systems, cooling systems, fuel gas, purge/vent systems, instrument air, etc.)
Plan and supervise mechanical pre-commissioning activities: flushing/cleaning, leak testing, alignment verification, preservation removal, reinstatement, and mechanical run readiness.
Interface with OEM/vendor reps and EPC/construction teams to coordinate installation verification, SAT support, and readiness for energization/start.
Lead equipment inspections and validation of key rotating equipment prerequisites:
Lube oil cleanliness verification, system flushing acceptance
Coupling alignment / soft foot checks
Barring gear operation and verification
Seal gas and dry gas seal system readiness (as applicable)
Vibration/condition monitoring readiness and baseline data capture
Support and/or lead dynamic commissioning and start-up activities:
First-fire support, break-in runs, trips testing support, and operational proving
Rotating equipment performance monitoring and troubleshooting during ramp-up
Drive safe work execution through hazard identification, commissioning risk reviews, PTW coordination, and compliance with site HSE requirements.
Manage mechanical punch list resolution (A/B/C classification as applicable), coordinate rework, and verify closeout prior to handover.
Provide field mentoring to junior engineers and discipline teams; drive consistent commissioning standards and best practices.

Required Qualifications

Bachelor’s degree in Mechanical Engineering (or closely related engineering discipline).
Senior-level commissioning experience with demonstrated leadership in LNG liquefaction train mechanical commissioning.
Extensive experience with rotating equipment commissioning for Baker Hughes Frame 7 gas turbine-driven compression trains.
Strong familiarity with MR and PR compression equipment, auxiliaries, and associated balance-of-plant systems.
Proven ability to develop commissioning procedures and execute commissioning activities in high-hazard, operationally sensitive environments.
Strong troubleshooting capability across turbine/compressor train systems, lubricating oil systems, vibration behavior, and start-up constraints.
Excellent communication skills and ability to coordinate across Construction, QA/QC, Operations, OEMs, and client stakeholders.

Preferred Qualifications (Nice to Have)

Prior experience on large-scale LNG projects (EPC / owner / contractor environment).
Experience supporting performance testing, reliability run, and transition to operations.
Familiarity with commissioning systems/tools (turnover management, punch systems, completions databases).
Working knowledge of applicable industry codes/standards (e.g., API/ASME concepts relevant to rotating equipment and pressure systems).

Work Environment / Travel

Project-based, field role at LNG construction/commissioning sites.
Ability to work extended schedules and support critical path start-up activities (including nights/weekends as needed).
Must be able to work in industrial environments and comply with site access requirements.
