ADMIRALTY e-Nautical Publications

Fast and accurate NM updates

AENPs are updatable, electronic versions of official ADMIRALTY Nautical Publications such as Sailing Directions (Pilots) and the Nautical Almanac. This means that bridge crews can download and apply electronic weekly Notices to Mariners (NMs) updates to publications in just a few seconds every week, improving efficiency and accuracy on board during passage planning tasks.

Easier access to important information

Simple search functionality gives users quick access to important planning information. The AENP Viewer snapshot function helps bridge crews to view, save and print AENP pages as well as any applicable NMs and addendums, which can be used to support passage planning.​

Carriage compliance

AENPs are designed to meet SOLAS carriage requirements, contain the same official information as their paper equivalents, and have been approved by the Flag States of over 80% of ships trading internationally. AENPs can also aid inspections by clearly showing when a publication was last updated with weekly NMs.
