Use of universal protocol for entering the port of destination in AIS device

The Automatic Identification System (AIS) is an automatic tracking system used on ships and by vessel traffic services (VTS) for identifying and locating vessels by electronically exchanging data with other nearby ships and AIS Base stations. It is capable of sending and receiving ship information such as identity, position, course, speed, ship particulars and cargo information to and from other ships and shore. One such message includes a text field designated for destination. The mariner is able to enter the ship's destination into the AIS at the start of each voyage, and to keep this information updated. Evidence shows that mariners are using different names for the same location when entering destination data in their AIS units making it difficult for other ships and for VTS to identify the port uniquely. This situation leads to confusion and inefficiency in data interchange. Information about the destination allows to predict each other's courses, which will reduce the risk of collision and thus enhance the safety. Knowledge of the data on the port of destination contributes to the efficiency of VTS. Currently, this information is not provided for the exchange of AIS system. This can be achieved by using the existing destination field for entering both the port of departure and the next port of call. Therefore, there is a need to harmonize data input when entering port information, by adopting an available universal protocol. The International Maritime Organization (IMO) recommends the use of the United Nations code for ports and other locations (UN / LOCODE).
