With Shiptracker, Port of Rotterdam Authority is giving a fresh boost to the sustainability and efficiency of the logistics chain. Thanks to this online tool, ship arrival and departure times can be shown much more accurately. Shiptracker, which is currently being presented as a beta version, uses big data and machine-learning algorithms with information from the Automatic Identification System (AIS). This is a global system for the automatic identification and tracking of ships, allowing estimated times of arrival (ETA) to be generated much more accurately. Users can set notifications so that they receive an alert as soon as their chosen vessel moors.
