There are now exemptions from reporting for all vessels tracked with LRIT, AIS Class A, VMS, or functioning AIS Class B. Previously, the exemption for vessels with AIS Class B applied only when navigating in Isfjorden.
Those now required to report according to the regulations are vessels carrying passengers or those over 24 meters in length that do not have any form of automatic tracking as mentioned above.
