About this report
Undersea energy pipelines, power interconnectors, and submarine data cables have moved from being technical assets to being recognised as strategic vulnerabilities within the European Union.
Recent incidents and growing concern over hybrid threats have pushed the EU to formalise new legal obligations for the protection of critical underwater infrastructure, while simultaneously funding defence-driven technologies capable of monitoring the seabed at scale. This report sets out how those two tracks converge.
Key questions this report answers
- How do the EU's new legal obligations for protecting critical undersea infrastructure (pipelines, interconnectors, data cables) converge with defence-driven seabed-monitoring technologies?
- What role does acoustic signature intelligence play in EU defence programmes for monitoring the seabed at scale?
- How do civil resilience requirements and defence capabilities interact around undersea assets?
- What industrial and regulatory implications and market-entry pathways face new entrants?
Inside this report
- Introduction
- EU Critical Infrastructure Resilience Framework for Undersea Assets
- Acoustic Signature Intelligence in EU Defence Programs
