Approach & Key Message SeaSEC (Seabed Security Experimentation Centre) is the international testbed and innovation hub for the protection of Critical Undersea Infrastructure (CUI). During the SeaSEC Challenge Weeks 2025, 12 consortia tested existing technologies under realistic North Sea conditions. Outcome: advances in detection, situational awareness, and autonomous systems. In this session, SeaSEC shares the key lessons and calls on the supply chain (industry, suppliers, research institutions) to actively participate in future innovation and experimentation. Call to Action: Protecting our maritime lifelines (data cables, energy, oil & gas, offshore wind) demands an innovative, resilient supply chain. SeaSEC provides the platform, the industry must deliver.
