Europe’s subsea cable infrastructure is facing growing risks from geopolitical tension, climate impacts and a lack of preparedness, according to industry bodies.
The European Subsea Cables Association (ESCA) and the International Marine Contractors Association (IMCA) said regulatory barriers, skills shortages and the absence of readily available solutions are compromising the continent’s ability to repair damaged cables.
Their joint position statement was issued in response to the European Commission’s Cable Security Action Plan, which aims to improve prevention, detection, response and deterrence of threats to submarine cables.
Industry leaders welcomed the plan but warned that without closer collaboration between public authorities and the cable sector, Europe may fall short of the resilience now urgently required.
Subsea telecommunications cables carry more than 99% of global intercontinental data traffic, while power cables enable renewable power transmission and cross-border energy trading. Damage caused by fishing, anchoring, natural hazards or other incidents can disrupt financial systems, energy flows and communications in real time.
Repair operations are increasingly delayed by capacity constraints and outdated permitting regimes across EU member states, ESCA and IMCA added.
Telecommunications cables are currently supported by global maintenance zones and industry-led agreements, which have helped enable rapid mobilisation, though the supporting vessel fleet is ageing and suffers from limited investment certainty.
Power cable repair presents further challenges due to complex operations, diverse ownership structures and a lack of regulatory cohesion. Vessels may be engaged in installation projects when emergency repairs are needed, while cross-border permitting obstacles risk creating critical delays.
Power cables are larger and more complex to repair than telecommunications lines, the associations said, meaning delays can have more severe consequences.
