Job Purpose

To design, implement, and commission instrumentation and control systems for the greenfield project, ensuring seamless integration, safety compliance, and operational reliability in a batch chemical plant environment.

Principal Accountabilities

• Specify, select, and design instrumentation (flow, pressure, temperature, level, analytical) and control systems (PLC/DCS/SCADA) for the new plant.  \
• Ensure integration of instrumentation with electrical and automation systems for unified plant control.  
• Supervise installation, calibration, loop checking, and commissioning of all instruments.  
• Develop and maintain instrumentation documentation (datasheets, loop diagrams, calibration records).  
• Ensure compliance with safety standards (SIL, ATEX, PESO) and functional safety requirements.  
• Troubleshoot instrumentation and control issues in batch processes and provide effective solutions.  
• Coordinate with vendors, EPC contractors, and internal teams for timely project execution.  
• Support FAT/SAT, pre-commissioning, and startup activities.  
• Implement predictive and preventive maintenance strategies for instrumentation systems.

Major Challenges

• Integrating new-age instrumentation and control systems with legacy equipment during project phases.
• Ensuring functional safety (SIL) and hazardous area compliance in a complex chemical batch process.

Decisions

Independent Decisions:

• Instrument selection, specification, and vendor technical evaluation.
• Day-to-day commissioning and troubleshooting decisions.  

Decisions Requiring Approval:

• Major control system architecture changes.
• SIL verification and validation outcomes.

Interactions
