Further development of AIS

AIS was initially established as an anti-collision system for vessels. Today, AIS has an even greater range of applications.

For the Norwegian Coastal Administration and other authorities, AIS is a key tool that is used daily to ensure safety at sea. In addition to using AIS data to monitor traffic, the Norwegian Coastal Administration has integrated the data with several other applications in recent years:

Virtual Aids to Navigation (AtoN)

  • A virtual AtoN is a digital representation of an obstacle or a hazard at sea. The navigation mark is only visible in digital form, for example in a chart plotter on board a vessel, and does not exist in the physical world.
  • An AtoN is traditionally a physical navigation mark that warns vessels of hazards and obstacles at sea.
  • In the Norwegian Coastal Administration’s VTS, virtual AtoN systems are used, for example, to show vessels where there are moving objects or other vessels in the area.

Dynamic risk monitoring

  • Dynamic risk monitoring, where AIS is one of the data sources, is one of the decision-making support tools in the Vessel Traffic Service.
  • Based on historical AIS data, artificial intelligence uses algorithms to calculate the risk of a breach of regulations occurring in the maritime traffic in the near future.

Wind forecasts

  • AIS base stations transmit wind forecast data from the Norwegian Coastal Administration’s wind forecast app Kystvær to vessels’ AIS on-board receivers.
  • Navigators can thus see wind forecasts in the AIS system.
