Job Summary
The Laboratory Supervisor reports to the Process Manager and leads the laboratory function at Freeport LNG — including the Liquefaction facility, the Pretreatment facility, and other Company sites as required — in support of safe, compliant, and reliable LNG operations.
The role provides direct supervision, technical direction, and day-to-day leadership for laboratory personnel supporting the process units, environmental programs, and custody-transfer activities. It is accountable for maintaining a strong safety culture and operational discipline in a high-hazard industrial environment, and for ensuring analytical results are accurate, traceable, timely, and suitable for their intended use.
The Laboratory Supervisor serves as the laboratory’s primary interface with Operations, Engineering, Maintenance, Environmental/Regulatory, Commercial, and Projects, providing sound technical guidance and clear escalation when laboratory data, sampling conditions, or process context may affect safety, compliance, reliability, or business decisions.
Duties/Responsibilities
- Identify, assess, and mitigate hazards specific to laboratory and field sampling work, including flammable gas, cryogenic materials, toxic substances, and marine/dock operations.
- Select, develop, validate, and maintain analytical methods and sampling techniques for LNG and related process streams, including non-routine or modified methods.
- Perform, review, and validate complex laboratory analyses; operate, calibrate, maintain, and troubleshoot laboratory and online analytical equipment, including gas chromatographs; maintain sampling-system integrity, chain-of-custody, and sample representativeness; and reconcile laboratory data against process conditions, historical trends, and online analyzers in coordination with Process Engineering.
- Ensure laboratory analyses, sampling, calibration, and reporting meet quality and contractual expectations for LNG custody-transfer operations.
- Ensure environmental sampling and analysis programs (e.g., water, wastewater, and compliance monitoring) are executed, documented, and reported in accordance with regulatory and audit requirements.
- Lead and participate in internal and external audits; prepare documentation, address findings, and close corrective actions.
- Maintain laboratory facilities, sample systems, and consumables in safe, reliable working condition, and resolve issues affecting safety, quality, or operations.
- Support turnaround, incident response, and abnormal operations by prioritizing sampling and delivering timely, accurate analytical data.
- Participate in incident investigations related to laboratory operations, sampling, or data quality; identify root causes; and implement corrective and preventive actions.
- Review and provide input to Management of Change (MOC) for laboratory methods, sampling systems, analyzers, and related equipment or procedures.
- Manage staffing schedules and shift coverage for routine operations, outages, and critical activities, including workload and fatigue-risk controls.
- Perform other duties as assigned, consistent with training, competency, and safety requirements.
- Lead laboratory safety and risk management for all laboratory and field sampling activities in a high-hazard LNG environment.
- Direct laboratory operations and analytical services across all supported facilities — including process units, utilities, environmental sampling points, and custody transfer interfaces — in support of LNG production, product and feed-gas quality, process systems, environmental monitoring, and operational decision-making.
- Ensure analytical results, sampling practices, and reporting are accurate, traceable, and compliant with internal procedures, regulatory and environmental obligations, and contractual quality expectations.
- Own the laboratory quality management system, including QA/QC, data validation, corrective actions, and continuous improvement.
- Provide technical leadership and serve as the laboratory’s primary interface with other site functions on matters affecting safety, compliance, reliability, and business decisions.
- Supervise, develop, and manage the performance of laboratory personnel.
- Manage laboratory resources, including budget, staffing, equipment, calibration, and third-party services.
