Call content
short description
This call supports the upgrade of existing submarine telecommunications/digital infrastructures to “smart capabilities” enabling applications that monitor them as well as other surrounding critical infrastructures (e.g. power cables, pipelines, etc.) and/or their vicinity.
Call objectives
Under this call, CEF-Digital will support the upgrade of existing equipment to make fibre cable systems “smart”, either throughout the length of the cable, such as by attaching sensors, or by other probing techniques at the edge, to detect and monitor displacement, acoustic or other signals.
The specific objectives of this call are to:
- Enhance the security, resilience and overall performance of the submarine fibre cable infrastructure within or connecting to the Union by deploying smart cable technologies and sharing the data gathered by these smart cables with Regional Cable Hubs and/or competent national authorities as appropriate;
- Further promote the use of data gathered by smart cables with authorisedrelevant stakeholders (e.g. the scientific and academic communities for environmental monitoring purposes).
Applicants are encouraged to clearly demonstrate in their proposals the geostrategic importance of the proposed action, in view of the interests of the Union, notably to enhancing the level of security of the EU backbone infrastructure.
The implementation of smart cable systems will facilitate specialised applications in safeguarding critical infrastructure, which can be compromised by natural events, accidental activities, or deliberate sabotage. These systems will also collect data on environmental conditions, such as temperature and currents, as well as information on marine fauna for research purposes. Additionally, they will enable the detection of seismic activity, volcanic eruptions, or tsunami events, thereby providing the potential for early warnings to civil protection authorities.
Proposals should address the connectivity needs of a region or the whole EU, by integrating complementary routes that improve redundancy and include state-of-the art technological solutions, with clear benefits in terms of cost-efficiency and synergy between actors (stakeholders, regions, Member States, etc.). Cooperation with other actors to achieve the aforementioned benefits is encouraged and may be based on the reuse or extension of existing studies or works, sharing or upgrading capacities to fulfil the needs of the concerned stakeholders.
Activities may include studies, provided that they are necessary for the implementation of the project. This may include preparatory work required prior to signing a contract with a supplier (e.g. required permits).
Studies activities should be described and executed in separate work packages and can then benefit from the funding rate specific for studies (see Form of grant, funding rate and maximum grant amount). Note that the higher funding rate for works in outermost regions (see Form of grant, funding rate and maximum grant amount) does not apply to studies activities if included in the same proposal.

Expected effects and impacts
The expected impacts of this call include:
- Increased security and resilience of the EU's submarine cable infrastructure through the deployment of cutting-edge smart cable technologies, which will contribute to the digital sovereignty and strategic autonomy of the EU.
- Enhanced coordination and sharing of vital data among Member States, enabling the detection and monitoring of threats and facilitating appropriate responses to ensure the continuity of critical services across the Union.
- Advanced environmental monitoring (e.g. climate change) and enhanced civil protection against potential natural disasters, achieved by sharing pertinent data with the scientific community and relevant authorities.
Key performance indicators for this topic will include:
- The total length (km) and approximate targeted area (location, km2) of submarine cable systems (including cables’ name, owners) upgraded with smart technologies,
- the number of smart monitoring units installed along submarine cable systems, (number of devices and/or nodes),
- the number of different technologies used, and
- detection accuracy.

Expected results
Under this topic, indicative eligible activities are the following:
Preparatory and implementation activities (linked to works):
- Studies necessary for smart systems deployment, including identification of vulnerability areas of the critical infrastructures;
- Selection, installation, testing and commissioning of sensing and monitoring systems.
Deployment of smart cable infrastructure:
- Upgrade of existing submarine cable systems, either with integrated sensors (e.g. environmental, acoustic, vibration, pressure, etc.) or with appropriate dry plant equipment (e.g. interrogators).
Monitoring, detection and early warning systems:
- Installation of real-time surveillance, threat detection and monitoring platforms linked to cable systems;
- Deployment of data acquisition, processing and secure transmission systems for early warning purposes.
Interoperability:
- Assure standardised real-time interoperability (e.g. standardised data formats);
- Allow interconnection of monitoring systems and information exchange across relevant entities (e.g. regional cable hubs, emergency services, etc.).
Proposals funded under this topic may include synergetic (ancillary) elements relating to another sector of the CEF programme, i.e. energy and transport. When these synergetic elements allow to significantly improve the socio-economic, climate or environmental benefits of the project, funding may be provided as long as the cost of these synergetic elements does not exceed 20% of the total eligible costs of the project.
All proposals must describe, in section 0 of the application form, the ownership and control status of the supported infrastructure after completion of the project and describe the mechanism that will be used to share and grant access to data, including business models, if any.

other eligibility criteria
Specific cases and definitions
Exceptional funding — Entities from other countries (not listed above), namely entities established in third countries associated to the CEF Programme and entities established in third countries not associated to the CEF Programme are exceptionally eligible for projects of common interest, if the granting authority considers their participation essential for the implementation of the action, and on the condition that those entities provide security guarantees, approved, on the basis of national law, by the country in which they are established.
Legal entities that are established in EU Member States, but are not EU controlled, shall also be eligible to participate on the condition that they provide security guarantees, approved, on the basis of national law, by the EU Member State in which they are established.
In case the ownership control assessment concludes that an entity established in the EU is not controlled from an EU Member State, this entity will be notified of the outcome of the assessment and it shall be obliged to provide the security guarantee, approved, on the basis of national law, by the EU Member State in which it is established, within 30 working days of the receipt of the notification and at the latest before the signature of the Grant Agreement.
Please note that security guarantees are not required for EU controlled legal entities established in third countries associated to the CEF Programme.
Natural persons — Natural persons are NOT eligible (with the exception of self-employed persons, i.e. sole traders, where the company does not have legal personality separate from that of the natural person).
International organisations — International organisations are eligible. The rules on eligible countries do not apply to them.
Entities without legal personality — Entities which do not have legal personality under their national law may exceptionally participate, provided that their representatives have the capacity to undertake legal obligations on their behalf, and offer guarantees for the protection of the EU financial interests equivalent to that offered by legal persons.
