For vessel guidance Ghent Port Company (Harbour Master's Department) makes use of the ENIGMA port information system. This acronym stands for Electronic Network for Information in the Ghent Maritime Area.
ENIGMA comprises information on among other things expected arrivals and departures, recent arrivals and departures, berth occupation, recent shifts and vessel follow-up.
Shipping companies, shipping agents, companies… themselves enter all data on for instance vessels, tonnages and cargo. These data are not only important for traffic guidance but also for all financial and administrative transactions. For example, invoices and statistics are derived from them.
