Diesel Generator (DG) SME – Operator / Maintenance / Troubleshooting

Position: Diesel Generator Engineer - Level 2

Location: Abu Dhabi – Data Center

Role Summary

Own the reliability, performance, and compliance of site diesel generator
systems (prime/DCC/standby) including engines, alternators, controls,
paralleling/synchronizing gear, fuel systems, and auxiliaries—ensuring
guaranteed start, stable load sharing, and recovery to SLA after utility or
facility events.

Key Responsibilities

Operations

Supervise/execute weekly auto-start tests, black-building drills, manual/auto
transfers, and load transitions.

Manage start sequencing, warm-up/cool-down, and governor/AVR stability;
monitor kW/kVAR/PF and V/Hz limits.

Coordinate paralleled operation: droop/isochronous modes, kVAR sharing,
reverse power/under-frequency protections.

Maintenance

Plan/perform PMs: oil/coolant/filter changes, valve lash, belts/hoses,
jacket-water/space-heater checks, charge-air system, exhaust and flex joints.

Alternator care: insulation resistance/PI, bearing checks, AVR/PMG/AREP
inspections; bus/terminal torqueing.

Fuel system: bulk/day-tank integrity, polishing, water/sediment control,
microbial treatment, leak checks, level alarms & interlocks.

Conduct routine load-bank tests (resistive/reactive) and trending (start
times, crank duration, voltage/Hz recovery).

Troubleshooting

Diagnose start failures, hunting/surging, protective trips (overspeed, low
oil pressure, over/under-voltage, UFRO), fuel starvation, smoke/temperature
anomalies.

Perform RCA/CAPA; update parameters and restore to service within MTTR.

Controls & Integration

Manage genset controllers, sync modules, dead-bus/live-bus close logic,
breaker interlocks; interface with EPMS/BMS/DCIM.

Maintain event logs, trend data, firmware/config backups.

Compliance & Safety

Adhere to LOTO/PTW, arc-flash awareness, fuel handling/HAZMAT, spill response.

Keep records for audits (run hours, emissions where applicable), and ensure
standards alignment (e.g., ISO 8528 intent, site policy).

Vendor/AMC & Documentation

Oversee OEM contractors, verify service reports, manage spares & critical
kits.

Maintain as-builts, one-lines, test sheets, checklists, impairment logs.

Cross-Discipline Awareness

UPS ride-through basics, switchgear control interlocks, chiller plant restart
sequencing, fire/life-safety interfaces (e.g., fuel shutdowns), security access
during drills.

SLA & KPI Targets

Start Reliability: ≥ 99.9% successful starts.

Recovery: Voltage/Hz within spec in ≤ 10 s (site policy) after start; load
acceptance per OEM.

PM Compliance: 100% on-time; ≤2% approved deferrals.

Incident Reporting: P1 report ≤24 h; RCA/CAPA ≤5 business days.

Fuel Readiness: Minimum reserve hours met; water/sediment within limits; zero
uncontrolled spills.

Qualifications

Diploma/Degree in Mechanical/Electrical (or equivalent).

5–10 years with large industrial DGs (data center/critical facility
preferred).

OEM controller experience (e.g., Deep
Sea/ComAp/Woodward/Caterpillar/MTU/Cummins).

Technical Skills

Governor/AVR tuning, sync & load-share, reverse power/ROCOF basics.

Diagnostics using OEM tools; IR/PI testing; thermography; vibration/fluids
trending.

Familiar with NFPA 110 concepts (where applicable), ISO 8528 performance,
fuel chemistry & polishing.

Soft Skills

Clear comms during drills/incidents; disciplined shift handover and log
keeping.

Vendor supervision and stakeholder coordination for change windows.

Work Conditions

24×7 roster/on-call; mechanical rooms/yards; noise/fumes—strict PPE and
safety compliance.
