In addition to temporary (T) and preliminary (P) notices in Norwegian waters.
Gunnery Exercises, Warnings and Miscellaneous Notices
Miscellaneous notices, warnings and gunnery exercises are published in the pdf edition of Efs every 14 days. For vessels subject to registration, the Norwegian Hydrographic Service recommend that mariners read these notices.

Rig List The Norwegian Mapping Authority removes the rig list from its services as from 1 August 2024
The rigg list has become an outdated service, and has been replaced with other services such as NAIS (nais.kystverket.no) and the National Register of Aviation Obstacles. The Mapping Authority will therefore end the rig list service from and including 1 August 2024.
The rig list will not be updated after 30 June 2024.
