Key Responsibilities

1. Maintenance & Troubleshooting

• Lead preventive, predictive, and breakdown maintenance of field instrumentation across wellheads, gas/oil separators, manifolds, compressors, dehydration units, and flare systems.
• Troubleshoot and calibrate field transmitters (Pressure, Temperature, Flow, Level), control valves, smart positioners, shutdown valves (SDVs/BDVs), and solenoids.
• Maintain custody transfer and fiscal metering equipment (multiphase flow meters, orifice meters, turbine/coriolis meters, gas chromatographs).

2. Control & Safety Systems (PLC / SCADA / DCS)

• Support the operation and loop-checking of PLC/SCADA/DCS systems, RTUs, and Wellhead Control Panels (WHCP).
• Inspect, test, and maintain Emergency Shutdown (ESD), Fire & Gas (F&G) detection systems (toxic gas, combustible gas, flame detectors, manual call points).
• Read and interpret engineering drawings, including P&IDs, instrument loop diagrams (ILD), hook-up drawings, wiring schematics, and cause-and-effect matrices.

3. Supervisory & Field Operations

• Supervise junior technicians and contract personnel to ensure all site activities adhere strictly to Standard Operating Procedures (SOPs).
• Prepare daily instrument logs, maintenance reports, calibration records, and defect notifications.
• Manage site inventory of critical spares, consumables, tools, test benches, and calibration equipment (e.g., HART communicators, dry block calibrators, deadweight testers).

4. HSE & Compliance

• Strictly enforce Permit to Work (PTW), Job Safety Analysis (JSA), and Lockout/Tagout (LOTO) protocols for hazardous area activities (Zone 0/1/2, Class I Div 1/2).
• Ensure all equipment and installations comply with DGMS, OISD, PNGRB, and ATEX/IECEx standards.
• Actively participate in site safety drills, toolbox talks, and incident prevention programs.
