The purpose of the study will be to support the Submarine Cable Infrastructure informal Expert Group in the course of 2026/2027, notably by assessing regularly and providing recommendations aiming at improving the security and resilience of existing and new submarine cable infrastructures, and by supporting the deployment or significant upgrade of submarine cable infrastructures via Cable Projects of European Interest (‘CPEIs’). It is a direct follow-up of the Commission Recommendation (EU) 2024/779 on Secure and Resilient Submarine Cable Infrastructures and the implementation of the 2025 EU Action Plan on Cable Security. The reason for purchasing is the high level of specialisation required, especially as regards the economic and technological aspects of submarine cable infrastructures, as well as the necessity to swiftly deliver on this important topic relying on limited internal resources.
