Job Summary
Plant Design I/O is seeking an Instrument & Controls P&ID Validation Specialist to support the verification and validation of instrumentation and control information associated with a client P&ID walkdown project. This position will review the work completed by the P&ID walkdown team and validate instrumentation, control, and safety system information against available facility documentation and control systems.
The ideal candidate has previous experience as an Instrument Technician or in a similar industrial instrumentation role and possesses a strong practical understanding of field instrumentation, control loops, process controls, and industrial facilities. This position will use that experience to identify discrepancies between P&IDs, field observations, the Distributed Control System (DCS), safety systems, and other instrumentation and controls documentation.
This is a technical individual-contributor position and does not include personnel management or team leadership responsibilities.
Responsibilities
- Review P&ID walkdown markups and field documentation for instrumentation and control-related information.
- Validate instrument tags, instrument types, control valves, control loops, signals, and associated P&ID symbology.
- Review DCS information to verify instruments, control loops, process indications, alarms, and control functions represented on the P&IDs.
- Review Safety Instrumented System (SIS) and other safety system information to validate safety-related instrumentation, trips, interlocks, permissives, and shutdown functions.
- Compare P&ID information against available instrument indexes, I/O information, loop documentation, datasheets, cause-and-effect documentation, and other applicable instrumentation and controls documentation.
- Apply practical instrumentation experience to identify information that appears incomplete, inconsistent, or incorrect.
- Identify discrepancies between field observations, P&IDs, instrumentation documentation, DCS information, and safety system information.
- Clearly document discrepancies and provide the information necessary for corrections to be incorporated into P&ID updates.
- Identify conditions requiring additional field verification and communicate those requirements to the P&ID walkdown team.
- Work with the P&ID Walkdown Lead and client instrumentation, controls, operations, and engineering personnel to resolve conflicting or incomplete information.
- Verify corrected P&ID information to ensure identified instrumentation and controls discrepancies have been appropriately addressed.
- Maintain organized and traceable records of validation activities, discrepancies, and resolutions.
- Follow all client site safety, security, engineering, and documentation requirements.
Requirements
- Previous experience as an Instrument Technician or in a comparable industrial instrumentation and controls role.
- Strong practical knowledge of industrial instrumentation and process control systems.
- Experience reading and interpreting Piping & Instrumentation Diagrams (P&IDs).
- Experience working with common process instrumentation, including pressure, temperature, flow, and level measurement.
- Experience with control valves, switches, transmitters, analyzers, and other common field instrumentation.
- Working knowledge of instrument loops and the relationship between field instrumentation and control systems.
- Experience working with or navigating Distributed Control System (DCS) information.
- Familiarity with industrial safety systems, shutdown systems, interlocks, and associated field instrumentation.
- Ability to identify and understand instrument tags, loop numbers, equipment identifiers, and common ISA-style instrumentation symbols.
- Ability to compare information from multiple technical sources and identify discrepancies.
- Strong attention to detail and commitment to technical accuracy.
- Ability to clearly document findings and communicate technical questions and discrepancies.
- Ability to work on-site in an operating industrial facility and comply with all applicable client safety and security requirements.
Preferred Qualifications
- 5+ years of experience as an Instrument Technician or in a closely related instrumentation and controls position.
- Experience in chemical, petrochemical, refining, energy, manufacturing, or other process industry facilities.
- Experience working with DCS platforms such as Honeywell, Emerson, Yokogawa, ABB, Siemens, or similar systems.
- Experience with Safety Instrumented Systems (SIS), safety PLCs, or Emergency Shutdown (ESD) systems.
- Familiarity with instrument indexes, I/O lists, loop diagrams, cause-and-effect matrices, logic diagrams, and instrument datasheets.
- Experience troubleshooting or commissioning instrumentation and control loops.
- Experience performing P&ID walkdowns, drawing verification, as-built verification, or similar facility documentation activities.
- NCCER Instrumentation certification, ISA certification, technical degree, apprenticeship, or other relevant instrumentation training.
What Success Looks Like
- Instrumentation and controls information identified during P&ID walkdowns is thoroughly and accurately reviewed.
- Instrument tags, instrument types, control functions, loops, and safety-related instrumentation are accurately represented within the defined project scope.
- DCS and safety system information is effectively used to identify and resolve discrepancies in P&ID information.
- Differences between field conditions, P&IDs, instrumentation documentation, and control systems are clearly identified and documented.
- Items requiring additional field investigation are returned to the walkdown team with clear information regarding what needs to be verified.
- Technical assumptions are avoided, and conflicting or incomplete information is appropriately escalated for resolution.
- Validation records are organized and traceable so that P&ID changes can be supported by the underlying verification information.
- Work is completed safely, accurately, and in accordance with client standards and project requirements.
