Europe’s Seabed Security Test

Europe’s strategic autonomy now depends on infrastructure that is largely invisible, privately operated and difficult to replace quickly.

Submarine telecommunications cables, electricity interconnectors, offshore energy links, pipelines, landing stations, ports, repair vessels, sensors and maritime-surveillance systems form the physical layer through which European connectivity, energy security, financial continuity and public authority operate.

This analysis answers: What comprises Europe's seabed strategic infrastructure - submarine cables, interconnectors, pipelines, landing stations and surveillance systems? How do the legal/institutional architecture and the physical layer interact to expose European connectivity, energy and financial continuity? Which actors in the industrial and financial value chain (repair vessels, sensors, operators) shape seabed security, and where are the gaps? What are the strategic and finance implications of protecting privately operated, hard-to-replace seabed infrastructure?
