The project required the secure integration of more than 90 multi-vendor Operational Technology (OT) packages across multiple regions and automation platforms.

Key Challenges

  • Integrating diverse systems and technologies from multiple vendors.
  • Ensuring compliance with international cybersecurity standards.
  • Coordinating technical and operational requirements across multiple stakeholders and regions.
  • Maintaining system availability and operational integrity while implementing cybersecurity controls for offshore operations.

Solution Adopted

Apeiron provided comprehensive OT cybersecurity engineering and EPC support throughout the project lifecycle. The scope covered cybersecurity governance and requirements management, OT security risk assessments and gap analyses, system architecture reviews, firewall implementation, OT asset inventory management, compliance assurance, and cybersecurity validation through FAT, SAT, and operational readiness assessments. The project followed IEC 62443 and industry-specific regulations to establish a robust cybersecurity framework.

Tangible Benefits

The solution strengthened cybersecurity across all OT systems, improved compliance with industry standards and regulatory requirements, increased visibility and monitoring of critical assets, and reduced operational risk. It also enabled secure remote access, improved cyber resilience, and protected the FPSO against evolving cyber threats while maintaining safe and reliable production. Overall, the cybersecurity programme increased operational resilience, reduced downtime risk, and supported the facility's long-term sustainability.
