The Baltic Sea is a busy sea. At any given minute, about 2000 vessels are operating year in, year out. This increases the risk of a major incident at sea or in ports, especially when chemicals are involved. In the worst-case scenario, a chemical tanker collides with a passenger ship. The ResQU2 project platform improved the emergency preparedness of rescue authorities and services, seaports, and other authorities in the Baltic and the North Sea regions.
