Comprehensive coverage​​ of light and fog signal information

Keeping bridge crews informed, compliant and up-to-date, ADLL contains comprehensive coverage of more than 85,000 individual fixed light structures including Lighthouses, Lightships and Fog signals. ​ADLL also contains a number of Lit floating marks including Pontoon lights, resilient and buoyant beacons, Single Point Moorings (SPM) & Floating Production, Storage and Offloading Facilities (FPSO)​.​

This global coverage is divided into 10 folios, giving lights information for locations across the world.​


Fast and efficient upd​​ates 

ADLL allows users to download weekly electronic updates by internet or disc. These can be applied accurately with minimum manual intervention; significantly reducing time spent making manual updates and minimising the risk of human error on board.  


Overlays to support voyage planning​

Easy to use and clearly displayed using a growing number of back-of-bridge software, including ADMIRALTY e-Navigator Planning Station, ADLL can be viewed as a single layer on top of official navigational charts. By using this functionality, bridge crews can view relevant navigational information in one place, making it easier to plan voyages and view intended routes in detail.

Easy search and print ​​options​​

Crews can find lights information quickly using the map interface, the ship’s position or a keyword search. This information can then be easily printed for use in navigational activities such as passage planning.


Compliance with SOLAS requirements​​

ADLL is widely accepted as meeting SOLAS carriage requirements and is approved for use by the Flag States of over 80% of ships trading internationally; meaning ongoing safety and compliance for your ships, cargo and crew.

Find out below on the Compliance tab, which Flag States have approved the use of ADLLs.

Familiarity and reassurance​​

ADLL displays information using easily recognisable formats from printed publications, providing reassurance for users as they switch to digital applications.​​


Approved by the Flag States of over 80% of ships trading internationally, ADLL provides the same level of compliance as traditional ADMIRALTY paper-based publications, for ships trading under these Flag States. Where we are aware that a Flag State Authority (FSA) has issued documentation on the acceptance of UKHO’s digital nautical publications or provided guidance on their use, we have listed it in the table below. 

Important notes:​​

    • ​FSAs who accept UKHO’s digital nautical publications, but ​have not issued any specific requirements, may not be listed

    • If it is not clear whether a FSA accepts UKHO’s digital nautical publications as satisfying carriage requirements then shipping companies should contact their FSA or the appropriate RO
