Baltic Sea e-Nav

The project Baltic Sea e-Nav creates the next generation of navigational products and services compliant with new international standards, enabling national authorities and other maritime organisations to ensure safer, more harmonised and eco-efficient navigation at the Baltic Sea. The development of the new generation of digital navigational charts is the focus of the EU project in the Baltic Sea, funded by the Interreg Baltic Sea Region.

The Danish Geodata Agency and a number of partners are testing the next generation of navigational charts in the Baltic Sea region as part of the project. During the project, DGA will focus mainly on testing the next-generation electronic navigational charts and defining new S-100 production processes. DGA has started to develop prototype S-101 and S-102 products within the test areas.

Project summary

Ship navigation is facing a paradigm shift. Finally, full digitalization of navigational charts (maps at sea) will help reduce the negative impacts of shipping on the marine ecosystem and make the sector more sustainable. When developing navigational products from today’s standards, which are best compared with an early 2000s car navigator, to the new S-100 standards, which are more to equate with complex but user-friendly Google Maps, navigators will be able to plan more energy efficient routes, avoid safety risks and plan operations with extra sensitive areas taken into consideration.

The blue data will also be a valuable asset in marine spatial planning and for making better decisions when navigating at sea, especially to help all ocean activities to safely co-exist. This project will lever the value of this data and start the implementation of the S-100 products.

To unlock this potential and ensure seamless navigation in the Baltic Sea, there is a need for transnational cooperation. Without such an effort, the delays of some countries due to varying maturity level will affect the availability of the latest navigational products for shipping in the Baltic Sea. It will as a consequence also affect the implementation of the EUSBSR and a transition to a sustainable blue economy. After implementing the Baltic Sea e-Nav base package, the partnership will continue to build upon the project's results, under a robust transnational governance model, even after the project ends.
