· Support ABB and other manufacturer-specific flow computers, gas chromatographs, pressure and temperature transmitters, and associated measurement instrumentation.

· Verify meter performance, measurement repeatability, flow computer configuration, signal integrity, and instrument calibration status.

· Support gas chromatograph validation and verification of gas composition, molecular weight, compressibility, heating value, and other parameters used in fiscal calculations.

· Perform meter proving, calibration, meter factor verification, and measurement system checks in accordance with approved procedures and applicable contractual requirements.

· Assist with custody transfer measurement calculations, including volume correction, energy calculations, and reconciliation of measurement discrepancies.

· Support LNG loading and unloading measurement systems, including applicable LNG flow meters, tank gauging, level measurement, density measurement, and associated instrumentation.

· Maintain accurate calibration certificates, proving records, meter configuration files, audit trails, and measurement documentation.

· Ensure custody transfer systems comply with applicable contractual measurement standards, company procedures, and relevant industry requirements, such as AGA, API, and GPA standards.

3. Continuous Emissions Monitoring Systems (CEMS)

· Perform routine inspection, preventive maintenance, calibration, troubleshooting, and repair of CEMS equipment associated with LNG facility emissions monitoring.

· Maintain applicable extractive or in-situ emissions monitoring systems, including sample probes, heated sample lines, sample conditioning equipment, analyzers, and calibration gas systems.

· Troubleshoot and maintain analyzers measuring emissions parameters such as NOx, SO?, CO, CO?, O?, and other regulated components, depending on the facility's permit requirements.

· Perform zero, span, calibration drift, and response checks in accordance with approved procedures and applicable regulatory requirements.

· Support required quality assurance and quality control activities, including applicable Relative Accuracy Test Audits (RATA), cylinder gas audits, and other compliance testing.

· Investigate analyzer alarms, failed calibration checks, data gaps, and abnormal emissions readings.

· Verify the integrity of analyzer signals and data transmission to the distributed control system (DCS), plant historian, and environmental data acquisition systems.

· Maintain CEMS records, calibration logs, maintenance histories, and documentation required for environmental reporting and regulatory audits.

4. Instrumentation, Control Systems, and Field Maintenance

· Troubleshoot analog and digital instrumentation signals, including 4–20 mA, HART, Modbus, and other applicable industrial communication protocols.

· Inspect and maintain pressure, temperature, flow, level, and analytical instrumentation associated with LNG processing, utilities, storage, and loading systems.

· Support integration of analyzers and metering equipment with DCS, PLC, SCADA, flow computers, and plant monitoring systems.

· Read and interpret P&IDs, instrument loop diagrams, wiring diagrams, electrical schematics, instrument data sheets, and technical manuals.

· Conduct loop checks, signal verification, functional testing, and instrument commissioning activities.

· Identify recurring equipment failures, recommend corrective actions, and support root-cause analysis to improve equipment reliability.
