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 office located in St. Johns, Antigua and supported by two satellite offices in Germany – ADOMS Oldenburg and the ADOMS Inspection and Investigation Division (ADOMS IID), Elsfleth. The Maritime Administration operates within the regulatory dimension of the International Maritime Shipping Industry. These three offices work in close liaison 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.

ADOMS also has various regional offices based in Dubai, Piraeus, Valetta, and Miami where registration agents are available to facilitate ship registration and associated services. These offices in Dubai, Piraeus, Valetta and Miami also maintain a 24-hour emergency support for the vessels registered through these locations to optimize customer interaction and communication.

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.
