The Flag


The Antigua and Barbuda Department of Marine Services and Merchant Shipping (ADOMS) is the Maritime Administration of Antigua and Barbuda and is responsible for the Ship Registry with its principal/head office located in St. Johns, Antigua and supported by two satellite offices in Germany – ADOMS Oldenburg and ADOMS Inspection and Investigation Division (ADOMS IID), Elsfleth.  The Maritime Administration operates within the regulatory dimension of the International Maritime Shipping Industry.

The three offices work closely together and the time difference between Antigua and Germany results in an extended period each day when customers can reach an open office. This in conjunction with the 24 hour/day emergency telephone line enables customers to always have access to quality support including the issuance of documentation when necessary.

Coupled with its customer service focus, ADOMS applies the most modern standards of safety with competitive fiscal and other incentives to meet the needs of ship and yacht owners seeking an effective registry option. Antigua and Barbuda has modern national legislation, covering all aspects of safety, security, seafarers’ welfare and the requirements for cleaner oceans.

The Headquarters, (St. John’s)

The headquarters, located in St. John’s Antigua, maintains the ship registry and is responsible for IMO representation, setting strategy, policy, legislation, and ship registration.

ADOMS Oldenburg

ADOMS Oldenburg provides direct services to customers located in Germany and is able to complete registrations, arrange to record mortgages, and provide certificates, exemptions and other critical documents quickly and efficiently. This office also manages the STCW certification process for Antigua and Barbuda ships, maintains the records of these, and issues endorsements and seafarer’s books.


ADOMS IID is responsible for the planning and arrangements for annual safety inspections and the investigation of marine casualties.

The Ship and Yacht Registry

Antigua & Barbuda operates a fully-fledged international registry and is consistently ranked among the top of the world’s merchant fleet.  Further, it is internationally well recognised by ship owners, international ship financing banks, Port States, Flag States and the International Maritime Organization (IMO).

The Antigua and Barbuda flag is recognized as a quality flag which is evidenced by our listing on the ’white’ list for the Paris and Tokyo Memoranda on Port State Control.

Antigua and Barbuda has a worldwide coverage of over 200 inspectors for its commercial ships and has signed agreements with ten Recognized Organizations and Recognized Security Organisations, all of whom are International Association of Classification Societies (IACS) members, who act for and on behalf of the Administration to perform statutory surveys, inspections and issue statutory certificates on its behalf.

Antigua & Barbuda continues to be on the IMO ‘white’ list of flag States for the STCW Convention to which it gives full and complete effect.



As the Maritime Administration of Antigua and Barbuda, ADOMS aims to promote an internal culture that consistently targets customer satisfaction through the provision of a quality service that meets their needs; whilst ensuring compliance with international maritime conventions in the areas of maritime safety and security, environmental protection and the welfare of seafarers.



ADOMS aims to be recognized as the first choice global supplier of high quality services to the maritime industry with absolute regard for safety, security and environmental protection balanced with a commitment to quality customer service.



ADOMS is committed to high standards and to maintaining its international reputation. The organisation is certified to the ISO 9001:2015 standard.
