Norwegian Maritime Authority

The Norwegian Maritime Authority’s objective is to promote high standards in safety at sea for crews, vessels and the marine environment.

The Norwegian Maritime Authority (NMA) is responsible for all ships flying the Norwegian flag. The responsibility includes supervising the building and maintenance of Norwegian vessels. The NMA works to encourage shipping companies to maintain high standards of safety as well as minimizing harmful emissions.


The NMA is also responsible for the development and administration of all legislation for the environmental and safety aspects of shipping. The agency is further required to inspect 25% of all foreign-flagged ships calling at Norwegian ports, in order to oversee their compliance with international regulations.


Norway puts much emphasis on international cooperation on maritime safety and security, protection of the marine environment and seafarers' competence and working and living conditions. The NMA works to achieve its objectives through the UN agencies IMO and ILO and the European Union.


As a seafaring nation, Norway is aware of the importance of high-quality shipping and competent seafarers. The NMA supervises the certification of seafarers as well as their working and living conditions. The crews on board Norwegian ships enjoy a variety of culture and leisure services supplied by the NMA through its welfare stations and partners in many ports around the world.


The Norwegian Maritime Authority is subordinate to the Ministry of Trade and Industry, and to the Ministry of the Environment in matters concerning the prevention of marine pollution from ships. The NMA also assists the Petroleum Safety Authority in enforcing the Petroleum Act on the Norwegian Continental Shelf.
