Marine Viewer

The MARVIEWER program enables users to see a map of where ships are located around the globe, whether on passage, at anchor, or berthed in port. The program cannot be invoked directly from the NOVUS shortcut field but is available when details are entered into the RISKDETMA program.

The View on Map button links directly to the Marine Traffic website which shows an up to date map of every registered vessel that has an Maritime Mobile Service Identity (MMSI) number.

The MMSI number is a unique nine-digit number that is registered with an AIS (automatic identification system) unit. This unit tracks signals from ships’ transponders to inform vessel tracking services, and to monitor vessel movements.

AIS units are required on vessels of more than 300 gross registered tonnes. In certain circumstances vessels can turn off their AIS transponders.


The map displays colour-coded positions of cargo vessels, tankers, passenger vessels, high-speed craft, tugs and special craft fishing vessels, pleasure craft, navigation aids and unspecified ships. It also shows the position of buoys, light vessels, and channel markers.

The MARVIEWER map will only be displayed for the vessel if the correct MMSI number is entered in the MMSI field. This is found in the main tab on the information section for the risk. If there is no MMSI number entered into this field, NOVUS will display RISKMAP for the risk.
