In the last years a joint Working Group of Priority Areas 1a (Inland Waterways) and 11 (Security) of the EU’s Danube Region Strategy developed a set of so-called Danube Navigation Standard Forms (DAVID). Using the expertise of stakeholders from the shipping sector and control authorities, the data fields of three often used forms (arrival and departure forms, crew lists and passenger lists) were harmonised in an international effort. In the first phase Hungary, Croatia and Serbia introduced the DAVID forms in control procedures thereby replacing the national forms applied until then. Romania, Bulgaria, Ukraine and Moldova – the four other Danube riparian states – intend to follow suit until the end of 2021 latest.
