ESD Replacement Project
Enven was commissioned with Honeywell Integrated Control System. This integration of DCS and ESD
had its pros such as unified HMI but there were massive reliability issues ranging from ESD card failures
to dependence of ESD on the DCS and Ethernet network for safety and control actions. Keeping in view
these issues, it was decided to replace Honeywell’s ESD: Safety Manager with more reliable, robust and
state of the art Schneider Electric’s ESD: Triconex.
Plant-2 ESD Replacement Project was one of the most challenging projects I&E has ever executed be it
the criticality, the technicality or the high stakes involved. ESD Project was first ever I&E project to be on
the critical path of the turnaround. The commissioning took place in the limited window of TA-18. It was a
humongous task to shift more than 3000 hardwired loops, test each loop, simulate and test 150 plus
interlocks and test each of the 325 HMIs in this short span of mere 21 days. Focused efforts and detailed
working in the pre-commissioning and commission phase made it possible to have a flawless execution.
The project team comprised of Asad Naeem, Mohsin Mukhtar Khan, Muhammad Hamza Khan, Khalid
