ATUL KAMBLE

Engineering Documentation & Design Support:

• Worked on the preparation, verification, and continuous update of the Instrument Index , ensuring consistency with latest P&IDs, loop drawings, and field instrument tags.
• developing and maintaining the I/O List for DCS and PLC systems, mapping analog and digital signals, and confirming allocation with system integrators during commissioning and FAT/SAT stages.
• Reviewed and updated instrument datasheets as per process requirements, vendor documents, and international standards (ISA, API, IEC).
• generating Instrument Location Layouts, Cable Routing Drawings, JB Schedules , and Hook-up Drawings in coordination with the design team.
• Supported in preparing Loop Diagrams , identifying wiring and signal paths from field instruments to control systems

Material Requisition and Procurement Support:

• Material Requisitions (MRs) for instruments, accessories, tubing, fittings, control valves, impulse lines, etc., based on datasheets and BOMs.
• Participated in Technical Bid Evaluations (TBE) by comparing vendor offers against specification sheets and refinery standards.
• Coordinated with the stores and procurement departments for tracking material deliveries, issuing Material Requisition Notes (MRNs) for site requirements, and verifying received items against purchase orders and technical specs.

Field Instrumentation Work:

• Followed safety standards and permit-to-work (PTW) procedures for field maintenance activities.
• Carried out field identification and tagging of instruments based on updated instrument index and P&IDs.
• Conducted site surveys and coordinated instrumentation activities during shutdowns, breakdowns, and emergency maintenance.
• installation, calibration, loop checking, and functional testing of process instruments including:
  Transmitters (pressure, flow, level, temperature – HART and FF types)
  Control valves , on/off valves , solenoid valves , positioners
  Emergency Shutdown Valves (ESDVs) , MOVs , and interlock systems
  Switches , RTDs , Thermocouples.
• issuing instrument MRNs (Material Requisition Notes) for site-required spares and consumables, ensuring availability of critical items during shutdowns and routine maintenance.

Workshop Activities:

• Hands-on experience with major valve manufacturers including Fisher, Severn, Masoneilan, Baumann, Samson, and Cameron.
• Diagnosed valve issues such as leakage, actuator malfunction, trim damage, seat wear, and gland packing deterioration.
• Conducted lapping, seat replacement, seal and gasket changes, and trim reconditioning as part of overhaul process.
• Carried out functional testing and calibration of valves using hydraulic/pneumatic test benches and diagnostic tools (e.g., Fisher FIELDVUE, ValveLink, Masoneilan SVI II, and portable communicators like HART 475/Emerson AMS).
• Maintained and tested ESDVs integrated with SIS (Safety Instrumented Systems) for critical applications, verifying fail-safe operation, response time, and proper solenoid valve functioning.
• Maintained detailed records of valve history, overhaul reports, test certificates, and ensured traceability as per QA/QC and ISO audit requirements.

Tools, Software & Standards Exposure:

• Gained exposure to industry tools like SmartPlant Instrumentation (SPI/INtools) , AutoCAD , MS Excel (for index/I/O management), and SAP PM for maintenance tracking.
• Learned and applied standards such as ISA S20 , API 551 , IEC 61511 , and ISO 9001 documentation procedures.
• Contributed to preparing as-built drawings , red-marking changes in documentation during site modifications, and updating document control systems.

• Assisted instrumentation engineers and senior technicians in both field and office-based tasks across multiple refinery units including CDU, VDU, Hydrocracker, SRU, Reformer, and Utility sections .
• Gained practical experience in handling instrumentation from reputed brands like Emerson, Yokogawa, Honeywell, ABB, and Siemens .
• Participated in loop checking, signal testing, and instrument tagging during commissioning and turnaround activities.
• Assisted in the preparation, verification, and updating of key engineering documents such as the Instrument Index , I/O List , Cable Schedule , Loop Diagrams , and Instrument Datasheets for various refinery units.
• Assisted in identifying and tagging instruments as per P&IDs and maintained the Instrument Index to ensure alignment with current site conditions and design revisions.
• Collaborated in cross-checking I/O lists with DCS/PLC system configuration , ensuring proper allocation of analog/digital input-output channels during commissioning and maintenance.
