The statistics by HELCOM show that the density of maritime traffic and transportation of dangerous cargoes by ships in congested waters of the Baltic Sea has grown. This demands new solutions for safe navigation and clean shipping at the Baltic Sea. The MaDaMe project supports national authorities that are responsible for the maritime traffic management. The challenge for target groups has been addressed in EUSBSR PA Safe, and according to Action 3, focus should be on developing reliable systems for maritime traffic management including digitalization. New digitalized services need to be provided by project target groups to fulfill the goal of this EUSBSR Action. All services and systems must be cybersecure-by-design. The project addresses the challenge by offering digital information sharing and messaging services for fairway users as a solution for safety and clean shipping. By producing digital solutions and making the information needed for safe shipping better available, the project's outcomes will improve navigation safety and security and contribute to the achievement of sustainable shipping in the BSR region. The development of clean shipping is supported as the offered services enable also the optimization of ship operations. For whole BSR region the project supports innovative business development within shipping industry and project mitigates potential conflicts among users of the sea space and facilitates its joint use.
