Normally, such permits will be issued with a validity of one year. Personal protective equipment must be CE marked in accordance with national law in an EU member State or a country covered by the EEA Agreement and implementing the directive on personal protective equipment.

Non-fixed offshore diving systems and their composition must also be surveyed and approved by the Danish Maritime Authority and, on the basis hereof, a permit is issued to operate in the Danish territory and Danish continental shelf area. This permit is issued for each individual diving operation.
