ACCSEAS wishes to improve maritime access to the NSR by developing & implementing e-Navigation within a transnational framework. A North Sea e-Navigation test-bed will be established to demonstrate proof-of-concept solutions. ACCSEAS enables service providers, researchers & suppliers to develop e-Navigation regional services and to prototype novel marine navigation & communication concepts. ACCSEAS provides the basis for alleviation of congestion, bottlenecks and accident risk, improving NSR access, with sustained cooperation & actions after the project.
