Maritime traffic real-time map

On the 12th and 13th September 2018, CMRE participated in the first MARISA Northern Sea Operational Trial. The trial was organised by TNO (Toegepast Natuurwetenschappelijk Onderzoek), the Netherlands Organisation for Applied Scientific Research, and hosted by the Netherlands Coastguard in their facility at Den Helder.


MARISA is an European Commission-funded project aimed at creating improved Maritime Situational Awareness though the delivery of a toolkit of data fusion services for maritime traffic monitoring and operational planning. The project foresees two trial phases covering five geographical areas.

In the first North Sea Operational Trial the Netherlands Coastguard organised the training exercise MARISA-Alert, covering three relevant operational scenarios in the Maritime Security and Safety domain.

During the trial CMRE successfully tested two MARISA services, namely, the Density Map and Multi-Source Dynamic Bayesian Network for Behavioural Analysis, jointly developed with Fraunhofer IOSB.

 The Density Map service successfully supported operators by displaying valuable information on vessel movement patterns. The Multi-Source Dynamic Bayesian Network for Behavioural Analysis service, on the other hand, was used to estimate the probability that situations or events of interest may occur by combining information from different sources of varying quality. Using live data from the Netherlands Coastguard surveillance system, the MARISA service generated accurate and timely alerts for the operator that corresponded to a targeted suspicious event.

The next two trials, respectively hosted by the Italian Navy and Greek Ministry of National Defence will take place in November, in the Ionian Sea and Aegean Sea.

MARISA European research project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement no. 740698.
