Live testing of ‘Avanti’, a new on-line web based application that provides validated nautical information for port users is due to commence at a number of European ports. Following successful prototype testing at Port of Rotterdam, the ports of Göthenburg, Marseille and Luela will commence live testing in spring 2014. Avanti has been developed by Envitia for the United Kingdom Hydrographic Office (UKHO) in collaboration with the International Harbour Masters’ Association (IHMA) and promises to make a major contribution to the rapidly expanding field of e-Navigation.
