Vessel details that can be changed in AIS transponders

How the Asian media discovered the name change and position of a superyacht of a Malaysian billionaire by using MarineTraffic and what kind of information can people change about their vessel and voyage on AIS

There was a lot of buzz in the Asian media last week about the name change of a superyacht that belongs to Jho Low, a Malaysian billionaire.

According to leading publications like The Straits Times from Singapore, the name of the vessel was changed from “Equanimity” to “Tranquility”, with journalists being alerted to this fact by following the yacht on MarineTraffic.

“MarineTraffic, a global ship-tracking site, shows that the vessel’s automatic identification system (AIS) reported the ship’s name to now be Tranquility,” reported The Independent, another newspaper from Singapore.

Are you wondering how one can change AIS information?

A vessel’s name, along with other basic information (IMO, MMSI numbers, flag, etc.) and related material regarding any ship, is all available and easily accessible through the MarineTraffic platform. Each Vessel Details Page includes all this essential information for the vessel and her voyage.

Using the Vessel Details page, one can discover the latest position of the vessel, her destination, the Estimated Time of Arrival (ETA), the average speed recorded and her past Itineraries.

Our system uses the information received from vessels, as it is transmitted by their AIS transponders. The information that is found in each AIS receiver is either dynamic or static.

Information such as the name of the vessel, as mentioned in the example above, belong to the second category (static). Static information is manually stored in the AIS by the vessel’s crew.

The vessel’s crew is responsible for adding and/or updating information related to the specific vessel or their voyage. Such information includes the vessel’s name, type and dimensions, IMO number, relative position of the AIS unit, the destination, ETA, and draught.

Dynamic information is automatically transmitted every two to ten seconds depending on the vessel’s speed and course while underway, and every six minutes while anchored from vessels equipped with Class A transponders.

Be it the name change of a vessel, even in mid-journey, or any other key detail change, “everything flows” according to the Greek philosopher Heraclitus.

In a world of ever-changing information, our goal at MarineTraffic is to ensure that each vessel on the Live Map has accurate, easily accessible information.
