Interoperability is the technical ability to exchange information between systems that were developed completely independent from each other.

CISE, launched in 2014, is gradually taking shape, while significant interoperability projects, including EUCISE2020 and national projects, have been successfully completed.

As CISE develops, it helps to bring about a significant political mentality change:

National and EU maritime authorities have come to realise that, by cooperating in exchanging information, they can work more efficiently and effectively

the European Commission said.

CISE is now ready to develop from an R&I product into an operational environment for structural information exchange. The transitional phase to operations, managed by EMSA, will enable further coordination in the next two years.

However, additional reflection will be necessary, also at political level, to make CISE fully operational and successful. The Commission intends to support CISE also under the next EMFF.


The Common Information Sharing Environment (CISE) has made important progress by entering its transitional phase (2019 - 2021) which will be managed and led by European Maritime Safety Agency (EMSA) in close cooperation with the Member States.

Integrated Maritime Surveillance aims to promote an effective understanding of all activities performed t at sea that could affect the security, safety, economy, or environment of the European Union and its Member States.

A common information-sharing environment (CISE) is currently being developed by the European Commission and EU/EEA members with the support of relevant agencies like the EFCA. It incorporates current surveillance systems and networks, giving all those authorities concerned access to the information they need for their missions at sea.

Funded via a grant of 3,5 million € by EMFF, the project builds upon the successful completion of the EU interoperability project EUCISE 2020, as well as upon the knowledge from important national projects.
