The overarching scope of each project in the programme is the complete replacement and upgrading of the compressor station's control systems to enhance cyber resilience. This involves modernising legacy infrastructure, implementing robust cybersecurity measures, and ensuring that the control systems are capable of withstanding evolving digital threats. The upgrades are intended to safeguard operational integrity, protect critical assets, and align with national and international standards for cyber-secure infrastructure.
