Admission: Danish ships

Decorative image

​​​​​​Only merchant ships can be admitted to the Danish International Register of Shipping. Fishing vessels and pleasure craft can instead be admitted to the Register of Shipping. It is, furthermore, possible for small fishing vessels and commercial vessels to be admitted to the Boat Register.

Registration of ships in the Danish International Register of Shipping (DIS)

Ships registered in the Danish International Register of Shipping have access to:

  • A number of advantageous economic framework conditions
  • A competitive tonnage taxation scheme
  • Tax-exemption for seafarers

Once the registration has been completed, we will issue a final certificate of nationality to the ship. The certificate of nationality documents that the ship is registered in DIS and that it is entitled to fly the Danish flag.

Which ships can be admitted to DIS?

In general, all Danish merchant ships can be admitted to DIS. However, the ship must have a minimum gross tonnage of 20 and must not be used commercially for fishing or boulder fishing.

Passenger transportation

Ships registered in DIS must not carry passengers between Danish ports, except for voyages to and from offshore installations.

Documents needed to be admitted to DIS

In order for a ship to be admitted to DIS, you must forward a number of documents to us. The documents are required to have a certain form, and we recommend that you familiarize yourself with these requirements when you intend to register a ship in DIS. The documents and the form requirements are described in more detail here:
