SIGA’s OT Cyber Security Solution Achieves ABS AiP for Integrated FPSO Defense in Partnership with Hanwha

Approval in Principle (AiP) has been granted by the American Bureau of Shipping (ABS) to the Integrated Operational Technology (OT) Cybersecurity Solution, jointly developed by Hanwha Ocean, Hanwha Systems, and SIGA.

This formal recognition confirms the architecture’s compliance with IACS Unified Requirements E26 and E27 – the maritime industry’s most stringent standards governing the cyber resilience of offshore and maritime assets.

The AiP confirms that the SecuAider® + SigaML² combined architecture – designed specifically for complex Floating Production Storage and Offloading (FPSO) operational environments – is feasible for deployment and, in principle, compliant with ABS Rules for Cybersecurity and the UR E26 framework governing onboard OT cyber robustness.

The combined solution integrates network-based monitoring with physical-process anomaly detection into a single console. This delivers enhanced situational awareness, early-stage threat detection, and resilient incident containment tailored for high-value offshore production systems.

An Industry-First Dual-Layer Defense

This achievement establishes a crucial precedent by validating a dual-layer defense architecture that provides full-spectrum OT cyber protection from Level 0 to Level 3. The framework’s strength lies in its ability to simultaneously secure OT networks and monitor the physical process behavior itself:

• SigaML²  –  an advanced process-layer (Levels 0-3) machine-learning solution that detects abnormal physical-process behaviors indicative of cyber manipulation or critical incident risks, and provides clear contextualization with AI-driven, real-time prioritized playbook recommendations.
• SecuAider® is a maritime-grade OT network security platform covering Purdue Levels 1–3, offering real-time threat detection, network visualization, and asset intelligence across supervisory and control networks.

Importantly, this AiP goes beyond a simple technical endorsement. By recognizing an integrated OT cybersecurity architecture that satisfies both UR E26 and UR E27 in FPSO environments, ABS has effectively validated a reference model that can be applied from the early design stage of future offshore production projects. This enables project owners and operators to confidently embed cyber resilience “Security by Design,” meeting tightening regulatory and class requirements from the outset.

Hanwha Ocean, Hanwha Systems, and SIGA will continue to advance and apply high-integrity OT security technologies across diverse industrial environments to ensure resilient and secure offshore production operations.
