Electrical and Instrumentation Inspector

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 (T1T6)
• 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 (420 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 (Ex01Ex04 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 Ex05Ex06 (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)
• ATEX Directive (2014/34/EU) and IECEx Scheme fundamentals
• Area classification principles (IECfor gasfor dust)
