Please note: The Danish Maritime Authority's employees in the district of Zealand work from home to avoid the spread of COVID-19.

Personal attendance at our main premises in Korsør is not possible.

However, documents can be submitted for ship registration. The offices in Jutland, Fyn and Greenland are open again.  

Some services may have extended case processing time, but the DMA still strives to provide its services, including response to inquiries by telephone and e-mail.

Ship registration
The Danish Maritime Authority's Register of Shipping will still be able to receive documents including documents for Daily Log. Registrations are expected to be done as usual - in some cases, however, with a slightly longer processing time. Processed documents cannot be expected to be delivered immediately after registration.

Certificates of competency
As a seafarer, you can still get your certificates so you can continue to sail.

Ship survey
As from 27 May, the DMA has reassumed ship surveying.

  • Al inquiries on ships surveys must be sent to email:  All inquiries will be processes as soon as possible.

If needed a survey postponed and/or a ship certificate extended, it requires an approval from the Danish Maritime Authority.

In the case of a classed vessel, an inquiry must be made to the classification society, which will coordinate with the Danish Maritime Authority.

  • For other ships, inquiries must be sent to the Danish Maritime Authority by e-mail:
  • Other requests for ship approvals etc. should be addressed to the Danish Maritime Authority by e-mail:

Medical care courses
