The ADOMS Busan Office
The ADOMS Busan Office is the regional office of the Antigua & Barbuda Department of Marine Services and Merchant Shipping (ADOMS) for the Republic of Korea and Japan. Thomas Blenk is Deputy Registrar for the Republic of Korea and Japan.
The office is operated by SolarisTech Inc. ADOMS maintains regulatory oversight and flag State responsibility from its headquarters in Antigua & Barbuda. Registrations, certificates, inspections, audits and approvals are acts of the Administration, or of an organization acting on its behalf, and registration of each vessel is subject to acceptance by the Administration.
The flag's services, in the region
A full service office for the Administration. Owners and managers in Korea and Japan can bring the whole file here: registration and change of flag, mortgages, certificates, seafarer documents, flag State inspections, ISM, ISPS and MLC audits, newbuilding work and technical support are all handled through the ADOMS Busan Office, for the Administration.
Registration and change of flag
Registration and transfer onto the Antigua & Barbuda register, handled in Busan. Registration is subject to acceptance by the Administration.
Provisional registration
Provisional registration can be issued, once the Administration accepts the application, so the vessel can trade while permanent registration completes.
Certificates
Certificates and documents of the Administration, handled in Busan.
Mortgage registration
Mortgages recorded in the Antigua & Barbuda register for permanently registered vessels, with the filing coordinated in Busan with the lender and its counsel. Priority runs strictly by the time and date of recording.
Seafarer documentation
Endorsements, Seafarer's Books and other seafarer documents, handled in Busan for owners, managers and manning agents.
Flag State inspections
Flag State inspections, arranged through the office around the vessel's trading pattern.
ISM, ISPS and MLC audits
ISM, ISPS and MLC audits, arranged through the office.
Newbuildings
Support through the build cycle for vessels building in Korea and Japan for the Antigua & Barbuda flag, including gas carriers and gas-fuelled tonnage, working with the owner, the yard and the vessel's Recognized Organization.
Technical support
Technical support for owners and yards. Technical policy decisions, including questions of convention interpretation, are made by ADOMS.
Change of flag to Antigua & Barbuda
In a change of flag, the new register has to open, the old one has to close, the mortgage has to follow, the crew's documents have to be in place and the certificates have to be aboard before she sails. The office handles the Antigua & Barbuda side of each step for the Administration and works with the owner and the previous registry on the rest.
