From FEED to First Gas: IEC 62443 Across the EPC Project Lifecycle

Deep End Era. Engineering with Sankalp · Oct 28, 2026 · 54m

Rafa Ortega, now on the operator's side, and Amira Saleh, the EPC contractor's control systems security lead, walk through four years of the train five project, stage by stage, from the first block diagram to the morning after first gas. Along the way: a cyber clause added to the FEED scope at the last minute, a 400-line handover register, a spreadsheet of passwords that should never have existed, and the commissioning firewall rule that came back to life. Part fourteen of The Deep End's 62443 series.
