    Modernization of the fire and gas system with supervision in Train "1" of the "BRN" site using a "Siemens S7-1500F" safety "PLC"
    (Université M’Hamed Bougara Boumerdès : Faculté des Hydrocarbures et de la Chimie, 2025) Bennaceur, Nadir; Cherif, Tarek; Chaib, Ahmed (Promoteur)
    This Final project focuses on the modernization of the fire and gas detection system of Train 1 at the BRN site operated by Sonatrach and ENI. The main objective is to replace the existing system with a more reliable solution that meets international safety standards, using an advanced safety controller. The project includes analysis of the current system, design of a new control architecture, integration of flame, gas, and smoke detectors, and development of a supervision interface for system monitoring. This modernization aims to improve detection speed, alarm response, and overall plant safety.

    Study of the «XGF868I» flare gas flow meter solution at the «HBNS Oil Field» with addressing its lack of data integration into the «ICSS» control system
    (Université M’Hamed Bougara Boumerdès : Faculté des Hydrocarbures et de la Chimie, 2024) Radjouh, Abderraouf; Chaib, Ahmed (Promoteur)
    This Thesis addresses the lack of detailed flare gas data and diagnostic data from XGF868i flow meters in the ICSS control system at the Groupement Berkine HBNS site. The solution includes creating 17 analog points, each one representing specific data retrieved from the flow meters via Modbus communication. Advanced configurations, such as alarm and historical data settings, were established for analysis and troubleshooting. Additionally, HMIs were developed for six flares, providing easy access from the control room and also enabling remote access through the Honeywell E-server solution. These enhancements contribute to safer, more efficient, and environmentally responsible operations.

    Automatisation de l’unité de la déshydratation du gaz naturel au complexe «GL1/K» en utilisant un automate programmable industriel Siemens
    (Université M’Hamed Bougara Boumerdès : Faculté des Hydrocarbures et de la Chimie, 2024) Ait Hammou, Mourad; Benlefki, Ahmed Wassim; Chaib, Ahmed (Promoteur)
    Ce Projet de fin d'études porte sur l'automatisation de l'unité de déshydratation du gaz naturel au sein du complexe GL1/K de Skikda en utilisant un automate programmable Siemens S7-400. L'objectif principal est d'isoler cette unité du système de contrôle distribué (DCS) pour faciliter la maintenance et améliorer la performance opérationnelle. Le rapport est structuré en cinq chapitres, couvrant la présentation du complexe, la description du processus de déshydratation, les instruments utilisés et le choix de l'automate, la programmation et l'implémentation du système de contrôle, ainsi que la supervision via WinCC. Les résultats montrent une amélioration significative de la fiabilité et de la gestion de l'unité, avec une interface utilisateur optimisée pour une supervision efficace.
