NITROGEN PURGING SUPERVISORY SERVICES (24HR OPERATION)

MAIN FUNCTIONS

• Supervise nitrogen purging activities for pipelines, vessels, tanks, process equipment, and process systems.
• Plan and coordinate nitrogen purging operations in accordance with approved procedures and work schedules.
• Verify system boundaries, isolation points, vents, drains, and nitrogen injection points before commencing work.
• Ensure nitrogen purging is performed safely and within approved pressure, flow, and concentration limits.
• Monitor oxygen levels and other relevant atmospheric conditions during purging.
• Supervise nitrogen supply, pressure regulation, hoses, manifolds, regulators, and associated equipment.
• Coordinate with operations, mechanical, commissioning, maintenance, QA/QC, and HSE personnel.
• Maintain continuous supervision during 24-hour operations and ensure effective shift handovers.
• Monitor operational parameters and respond promptly to abnormal conditions.
• Ensure all purging activities comply with approved procedures, PTW requirements, and HSE standards.

KEY RESPONSIBILITIES

• Review P&IDs, line lists, isolation plans, nitrogen purge procedures, and test packages before work begins.
• Develop or review purge sequences and ensure correct connection of nitrogen supply equipment.
• Confirm that all personnel understand the purge procedure, hazards, and emergency arrangements.
• Monitor oxygen concentration using calibrated gas-detection equipment.
• Control nitrogen injection pressure and flow to prevent equipment damage or unsafe conditions.
• Establish and maintain exclusion zones around nitrogen discharge and vent locations.
• Ensure adequate ventilation and warning signs are provided in affected areas.
• Monitor for oxygen-deficient atmospheres, especially in enclosed, confined, or poorly ventilated locations.
• Coordinate safe venting and discharge of nitrogen and displaced gases.
• Maintain accurate records of purge pressures, flow rates, oxygen readings, duration, and system status.
• Coordinate shift changes and provide clear handover information for continuous operations.
• Report leaks, equipment failures, abnormal readings, incidents, and unsafe conditions.
• Ensure nitrogen cylinders, tanks, vaporizers, manifolds, hoses, and other equipment are properly inspected and fit for service.
• Coordinate final verification and reinstatement of systems after successful purging.
• Prepare daily operational reports and completion documentation.
