Navionix provides rigorous on-site engineering support, field commissioning, and lifecycle maintenance for automation and process systems. Our experienced control systems engineers perform meticulous I/O loop checking, instrument calibration coordination, emergency PLC/SCADA troubleshooting, sequence optimization, and FAT/SAT protocol execution. We focus relentlessly on minimizing startup risks, eliminating unexpected delays, and ensuring flawless handover to plant operations.
Core Engineering Highlights:
Customized to your facility's P&IDs, electrical specifications, and operational cycle times.
What We Deliver
Our end-to-end scope covers every hardware, software, and documentation deliverable required for complete project sign-off.
Site Acceptance Testing (SAT) Execution
Rigorous step-by-step SAT execution validating all functional sequences, interlocks, fail-safe scenarios, and alarm responses.
I/O Loop Checking & Cold Commissioning
Verifying point-to-point field wiring, junction boxes, analog scaling (4-20mA, 0-10V), RTD/thermocouple curves, and digital I/O.
Emergency PLC/SCADA Troubleshooting
Rapid on-site or remote diagnostics for elusive hardware faults, communication drops, interlock lockouts, and software crashes.
PID Tuning & Dynamic Loop Optimization
Optimizing difficult temperature, pressure, level, and flow loops using frequency response and step-test analysis to eliminate oscillation.
Factory Acceptance Testing (FAT) Leadership
Hosting and managing structured FAT procedures in simulated staging environments before equipment is shipped to site.
Technical Operator & Maintenance Training
Comprehensive hands-on training for plant technicians covering routine diagnostics, alarm clearing, backup procedures, and safety recovery.
Typical Industrial Applications
Where Engineering Support & Commissioning is deployed to solve mission-critical operational challenges.
