IMRAN MANSURI
Jubail Industrial City
Summary
Instrumentation Specialist with 18+ years in polymer/petrochemical plants (15 years at S-CHEM). Expert in control valves/positioners (Fisher FIELDVUE DVC6200), TopWorx, smart transmitters (flow/level/pressure/temperature), and HART/FOUNDATION Fieldbus. Leads CM/PM, turnarounds, IEC 61511 proof testing, and ISA-18.2 alarm lifecycle. Converts failure history into playbooks and KPIs that reduce MTTR and recurrence while strengthening process safety.

Work History
Instrumentation & Control Lead (Acting Supervisor)
Saudi Polymers Company (S-CHEM)
02.2010 - Current
- Execute & troubleshoot instrumentation maintenance; lead daily/weekly planning with Operations/Planning.
- Calibrate/commission instruments (DP/flow/level/pressure/temperature); loop checks; as-found/as-left records.
- Control valves/DVC: guided setup, travel/pressure calibration, signatures & step-tests; booster placement & bleed tuning; FRL/vent-filter hygiene.
- Discrete valves (TopWorx): coupler fit, cam/dome alignment, switch thresholds, PLC debounce; solenoid/spool/vent maintenance; end-to-end PST.
- FOUNDATION Fieldbus: certify segments; verify pk-pk/noise/waveshape; enforce 2× terminators & single-point shield; maintain DD/DTM sets.
- Worked effectively in fast-paced environments.
- SIS & alarms: plan/perform proof tests per IEC 61511; implement ISA-18.2 KPIs (standing ≤5; ≤6 alarms/operator/hr); rationalize nuisance alarms.
- Vendor/MOC: RFQs, technical/budgetary evaluations, contractor oversight; reports via SAP/Excel.
