Our client, a leading energy provider operating a combined cycle power plant in Middle East, partnered with us as their process historian service provider to overcome several challenges with their existing historian system. Although the system was intended to integrate data from core sources such as turbine control systems, gas flow meters, weather stations, and others, it struggled with performance limitations and unreliable communication. Despite being connected to multiple systems, the historian often encountered inconsistent and inefficient data exchange. 

To address these issues and improve both data integrity and overall system performance, the client required historian upgrade services with enhanced integration capabilities and advanced technology.

Another significant challenge was data retrieval from an old RTU with the legacy IEC 101 serial protocol. The existing setup depended on third party software for internal data conversion to OPC 400 before integration with the historian. This software was outdated and unsupported, creating a dependency on obsolete components that limited overall system reliability, maintainability, and scalability. 

This O&G upstream facility’s OT network faced challenges in meeting client’s global IT/OT security standards. The existing Process Control Network (PCN) lacked centralized visibility of OT assets, and real-time threat monitoring was not in place, which exposed the network to potential security vulnerabilities and operational risks.

To mitigate these risks, an OT cybersecurity solution was deployed that included VLAN-based segmentation, role-based access control, anomaly detection, and enhanced system hardening. Additionally, centralised backup and patch management were implemented to ensure robust and secure maintenance, while keeping the OT network isolated from corporate systems in accordance with the Client’s strict cybersecurity policies.
