AIS Requirements

The Norwegian Coastal Administration has established a national network and system for receiving AIS signals from ships along the Norwegian coast in accordance with EU Directive 2002/59/EC.

The Norwegian Coastal Administration uses AIS information for maritime traffic monitoring, transport planning and oil pollution preparedness.

The UN's International Maritime Organisation (IMO) has implemented an international requirement for Class A AIS for vessels to which the SOLAS Convention from 1974 applies. This requirement can be found in Section V (Safety of Navigation) Regulation 19, which states that AIS equipment shall be operational as long as international agreements, regulations or standards do not require protection of the navigation information.

In Circular Series R, no. 05-2003, dated 30 June 2003, the Norwegian Maritime Directorate introduced a somewhat stricter requirement for Class A AIS than SOLAS with regard to the deadlines and what vessels are encompassed by the rules by an amendment of Regulations no. 660 and 701. This has been done in order to implement parts of the EU Directive 2002/59.

Vessels that are required to sail with Class A AIS transponders in accordance with the aforementioned requirements:

  • Tankers
                o All vessels in international trade
                o All vessels trading within the EU/EEA
  • Passenger vessels
                o All vessels in international trade
                o Vessels over 300 GT trading within the EU/EEA
                o High-speed boats over 150 GT in domestic trade 
  • Freighters
                o Vessels over 300 GT in international trade
                o Vessels over 300 GT trading within the EU/EEA
  • Fishing vessels
            o Vessels over 300 GT/45 metres trading within the EU/EEA

The carriage requirement was fully implemented on 1 July 2007.

Vessels that are not subject to the AIS carriage requirement

Vessels that are not subject to the carriage requirement can also be equipped with Class A AIS transponders if the owner/shipowning company finds this to be appropriate. Such vessels can also be equipped with Class B AIS transponders that are intended for use on smaller vessels and pleasure craft.
