Instrumentation Engineer Jobs in Qatar

Job Overview

Perform inspection of electrical and instrumentation equipment installed in potentially explosive atmospheres (hazardous areas) at Ras Laffan Industrial City. Verify compliance with IEC 60079 series, ATEX / IECEx standards, and site area classification. Act as the competent person for Ex equipment inspection.

KEY DUTIES

Ex Equipment Inspection

• Inspect Ex-rated electrical and instrumentation equipment in classified zones (Zone 1, Zone 2, and Gas Groups IIA, IIB, IIC), including:
• Motors – flameproof (Ex d), increased safety (Ex e), and non-sparking (Ex nA)
• Junction boxes – Ex e, Ex d, Ex tb
• Instruments – pressure transmitters, temperature sensors, flow meters, analyzers, and gas detectors
• Switchgear – Ex de, Ex e enclosures
• Cable glands, conduit systems, and sealing fittings
• Lighting fixtures, alarms, and beacons

Installation Compliance Verification

• Verify installation compliance with:
• IEC 60079-14 – Design, selection, and installation of Ex equipment
• IEC 60079-17 – Inspection and maintenance of Ex installations
• Check:
• Correct equipment grouping and temperature class (T1–T6)
• Proper ingress protection (IP rating as per area classification)
• Appropriate cable gland type (Ex d barrier glands for flameproof, Ex e compression glands for increased safety)
• Earthing and bonding continuity
• Armor terminating and drain/stop boxes where required

Inspection Types (Per IEC 60079-17)

• Conduct initial inspections (new installations before energization)
• Conduct periodic inspections (scheduled based on area zoning and risk assessment)
• Conduct sample inspections (spot checks for ongoing compliance)
• Inspection grades to include:
• Visual – identification of visible defects
• Close – detailed examination with covers opened (if safe)
• Detailed – full inspection with equipment partially dismantled (where permitted)

Area Classification & Documentation Review

• Review area classification drawings and verify:
• Zone boundaries (Zone 0, 1, 2 for gas; Zone 20, 21, 22 for dust)
• Equipment selection matches classification
• Gas grouping (IIA, IIB, IIC) and temperature class requirements
• Review equipment schedules, loop drawings, and instrument index

Deficiency Identification & Reporting

• Identify and document deficiencies including:
• Missing or illegible Ex labeling / rating plates
• Incorrect cable glands (plastic vs. metal, wrong type for Ex d)
• Damaged or corroded equipment entries
• Missing blanking plugs or stopping boxes
• Improper sealing or cable installation
• Failed earthing or jumpers disconnected
• Raise Inspection Findings and Non-Conformance Reports (NCRs) with photographic evidence and code references
• Follow up on corrective actions and close-out verification

I&E Instrumentation Activities

• Review:
• Loop testing records (4–20 mA, analog and discrete)
• Calibration records for instruments in hazardous areas
• HART communication and configuration files
• FOUNDATION Fieldbus (FF) segment documentation, wiring, and terminators
• Verify smart instruments are properly addressed and configured per loop drawings
• Witness loop testing or calibration if requested by client

Coordination & Reporting

• Liaise with client (QatarEnergy / operator), EPC contractor, and subcontractor E&I teams
• Attend pre-commissioning, inspection walkdowns, and punch list meetings
• Prepare and submit daily inspection reports, punch lists, and final Ex inspection dossiers

HSE & Permitting

• Follow Ras Laffan Hot Work and Electrical Work permit requirements
• Ensure gas testing is performed before opening Ex d enclosures (hot permit required)
• Participate in JSA / TBT before starting any inspection activity

MINIMUM REQUIREMENTS

• Valid CompEx Certificate (Ex01–Ex04 units as absolute minimum)
• Ex01 – Application of standards (IEC 60079-14 and 60079-17)
• Ex02 – Preparation and installation of Ex equipment
• Ex03 – Visual, close, and detailed inspection of Ex installations
• Ex04 – Maintenance, repair, and overhaul of Ex equipment
• CompEx Ex11 (Gas and dust) or Ex05–Ex06 (Ex tD dust) are advantageous

Experience

• Minimum 5 years of hands-on E&I inspection experience in oil & gas industry
• At least 2 years of dedicated Ex / hazardous area inspection experience
• Experience with greenfield (new installation) and brownfield (operating plant) inspections
• LNG, refinery, or petrochemical background preferred

Technical Knowledge

• IEC 60079 series – all relevant parts (0, 7, 11, 14, 17, 19, 31)
• ATEX Directive (2014/34/EU) and IECEx Scheme fundamentals
• Area classification principles (IEC 60079-10-1 for gas, 60079-10-2 for dust)
