Additional Flag States Approve ADP Products As SOLAS Compliant

The UK Hydrographic Office (UKHO) declared the additional flag States, Thailand and Moldova, have approved the use of ADMIRALTY Digital Publications (ADP) in place of their paper alternatives. ADP’s are essential paper publications produced by the United Kingdom Hydrographic Office (UKHO) that have been made available in digital form by Admiralty. ADP contains identical information to corresponding paper publications and are approved as meeting SOLAS carriage provisions. They provide mariners with efficient, intuitive and flexible navigation and planning of passages.


Thailand and Moldova-flagged vessels can take full advantage of ADP products while remaining in compliance with the SOLAS carriage requirements. These are the additional two of six flag States who have approved the use of ADP in the past six months. Supporting safe and efficient navigation around the world, they join the world’s leading flag States in drawing upon the benefits of the digital versions of ADMIRALTY publications. Admiralty Digital Publications allow bridge crews to access important information in an efficient and timely manner. These improved efficiencies enable crews to devote more time to decision making and less to administrative tasks.

ADMIRALTY Digital Publications (ADP) offers a world-leading range of digital nautical publications. Their product listing includes the following:

  • ADMIRALTY Total-Tide (ATT), accurate tidal predictions for more than 7,000 ports and 3,000 tidal streams


  • ADMIRALTY Digital List of Lights (ADLL), the world-leading source of navigational light and fog signals information


  • ADMIRALTY Digital Radio Signals (ADRS), a source of maritime radio communications for pilot and traffic services and international port operations


  • ADMIRALTY e-Nautical Publications (AENP), official ADMIRALTY Nautical Publications in a convenient electronic format – conducting improved efficiency, accuracy and access to information that bridge crews need. Comprising the same certified data as their paper equivalents.

“We are delighted that Thailand and Moldova join around 80% of the ships trading internationally who have now approved the use of ADP products in place of their paper equivalents. This is an important and welcome decision as it means that vessels can now take advantage of the benefits offered by ADMIRALTY Digital Publications for faster and more efficient voyage planning and navigation.”
