The Flagship Project was implemented through the "Baltic Sea Maritime Functionalities Project" (BSMF). The project was entirety aimed at development of maritime actors by defining cooperation, conceptualising maritime functions and creating target statuses in relation to them, and also to demonstrate these functions in the context of the Baltic Sea.The project’s objective was to create the viewpoint of the Baltic Sea region on European Union’s CISE (Common Information Sharing Environment for the surveillance of the EU maritime domain) project where all the actors are involved. The aim was to depict the maritime functionalities from the viewpoint of one state and to depict their connection to international exchange of information. However, while conducting the project, the existing development work (e.g. CISE TAG, MARSUNO) should be considered so that all overlap and possible competition will be avoided. Achievements: The Baltic Sea Maritime Functionalities – Awareness across boundaries (BSMF) project aimed at developing an information sharing environment for the maritime domain in the coastal countries of the Baltic Sea Region. The key conclusion of the project is that the number of different cooperative sectors should be reduced by creating only three different maritime functionalities – Safety, Security and Law Enforcement as well as Defence. Among the project ́s findings:• The international nature of maritime transport requires cross-border information sharing. Cooperation between participating countries should be arranged on the same basis and using the same standardized practices as in domestic information sharing. • Cooperation already exists inside sectors but promoting cross-sectoral cooperation to increase trust and understanding is required. • Management of maritime surveillance related information requires common national and international definitions. Single points of contact at national level should be used in order to secure inter-state communication
