Professional profile 01

Control systems from field signal to operator screen

Portrait of Mahmoud Atef

I work on brownfield automation and control-system projects in operating oil and gas facilities, combining control logic, field instrumentation and practical plant execution.

My strongest hands-on platforms are Allen-Bradley ControlLogix and Foxboro I/A Series. My work covers relay-to-PLC migrations, PLC and DCS logic, HMI development, I/O integration, alarms, permissives, interlocks, trips, loop checking, FAT/SAT, commissioning, start-up and plant troubleshooting.

I combine field-instrumentation knowledge with control logic and practical project execution. I collaborate with operations, maintenance, process and electrical teams, as well as contractors and vendors, to implement modifications safely and with minimal disruption to production.

I also use Python for engineering data analysis and repetitive technical tasks. For a Foxboro DCS expansion, I developed a utility to analyse configuration exports, identify unused I/O channels and validate the results against field wiring and engineering records.

Bridging field instrumentation, control logic and practical plant execution.

Selected project case studies 03

Brownfield control projects with practical outcomes

Three examples spanning relay-to-PLC migration, DCS expansion and owner-side furnace safeguard verification.

Case study 01

PLC modernisation · Compressor control

CompAir BroomWade Compressor Control-System Upgrade

Modernisation of an obsolete relay-based compressor control system while retaining the existing mechanical package and maintaining the plant air supply.

7-day cutoverNo plant shutdown

My role

Responsible for the internal control-system engineering scope, including relay-to-PLC logic conversion, HMI development, I/O definition, testing and installation supervision.

Challenge

The old control panel had to be replaced without shutting down the plant or losing the lead/lag/standby function of the compressor system.

Result

Completed the control-panel replacement in seven days without a plant shutdown, while improving system maintainability, diagnostics and future integration capability.

Engineering contribution

  • Prepared the detailed I/O list and selected the PLC, I/O modules and system power requirements.
  • Prepared control-panel layout and arrangement drawings and converted relay operating logic to PLC logic in Studio 5000.
  • Developed operator displays in FactoryTalk View and improved the lead/lag/standby operating sequence.
  • Developed a temporary pressure-band operating strategy to maintain the plant air supply during the cutover.
  • Performed I/O simulation, loop testing and cause-and-effect verification.
  • Led final installation, commissioning and start-up.

DCS expansion · LPG processing

LPG Plant Foxboro DCS Expansion and Loop Digitalisation

Brownfield expansion of the existing Foxboro I/A Series DCS to increase I/O capacity, integrate new equipment and convert pneumatic control loops to digital DCS control.

loops digitalisedPython-assisted I/O analysis

My role

Led the in-house DCS engineering and implementation activities for the expansion.

Challenge

The expansion had to fit within limited control-room space, minimise shutdown requirements and overcome poor visibility of unused channels in the existing documentation.

Result

Expanded DCS capacity, improved HART visibility and operator monitoring, modernised seven control loops and created spare capacity for future integration.

Engineering contribution

  • Defined new marshalling requirements; selected and integrated Foxboro FBMs, termination assemblies and intrinsic-safety barriers.
  • Added AI, AO, DI, DO, RTD, thermocouple, HART and Ethernet capacity.
  • Integrated three radar level gauges, two emergency diesel engines and a new gas-inlet skid.
  • Migrated existing HART transmitters and converted all old pneumatic loops within the plant to digital DCS control.
  • Configured I/O and control logic in IACC, developed FoxDraw graphics, and performed FAT, SAT and loop testing.
  • Retuned PID parameters for faster digital transmitters and intelligent valve positioners.
  • Built a Python utility to find unused FBM channels in Foxboro exports, then validated findings against documentation and field wiring.

Safeguards verifiedRedundancy & failover tested

My role

Owner-side Instrumentation & Control Engineer responsible for requirements definition, technical review, FAT/SAT participation, installation coordination and system verification.

Challenge

Modernise a legacy furnace control architecture while coordinating safety requirements, multidisciplinary installation interfaces and OEM delivery.

Result

The project delivered a safer, more maintainable furnace control architecture with forced-purge capability, improved flame detection and diagnostics, and verified safeguard and redundancy performance.

Engineering contribution

  • Verified safeguard functions, processor redundancy and failover during FAT and SAT.
  • Supported commissioning and plant start-up.
