In 2010, the EU required all EU Member States to develop a Maritime Single Window for the exchange of maritime administrative reports. Under Directive 2010/65/EU, the Maritime Single Window affected all vessels arriving in or departing from EU Member State ports.
To this end, EU Member States should improve cooperation between relevant authorities, such as customs, border control, public health and transport authorities, to further simplify and harmonize reporting formalities within the EU. Systems should optimise electronic technology for data transfer and information exchange, with the aim to eliminate, as much as possible, limiting factors to maritime transport. This ultimate aim of this is the establishment of a borderless European maritime arena.
Many EU ports have implemented this goal in their own way – the result of which is that there is no uniform reporting method for ships within the EU. Because individual data have to be submitted multiple times, the administrative burden has not decreased, as intended, but has significantly increased.
