Admiralty Digital Publications (ADP) are a collection of digital versions of the UKHO’s industry leading Admiralty Nautical Publications, used by mariners around the world.


ADP has been designed to meet SOLAS carriage requirements and, where approved by the vessel's Flag State, can replace the requirement for carriage of traditional Admiralty paper publications.


The Future of Navigation

Admiralty Digital Publications enable the mariner to make the transition from traditional paper publications to a new digital alternative. ADP forms part of the UKHO drive towards the digital future of navigation and complements the digital chart range of Admiralty products and services.


Official Data you can Trust 

All applications within ADP have been designed by the UK Hydrographic Office to meet the stringent navigational requirements of the commercial mariner. The data content is exactly the same as that provided in the equivalent paper publications but the digital format allows more flexible ways of viewing and searching for information.
