ADMIRALTY Maritime Security Charts contain safety-critical information to assist bridge crews in the planning of safe passages through high risk areas. All information has been gathered by the UKHO through work with NATO and other government organisations, ensuring each chart has the most accurate, up-to-date and verified information available.
Each Maritime Security Chart includes:
Information about dangers to the security of navigation including piracy, terrorism, embargoes, mine warfare, exclusion zones, blockades and illegal fishing. This information, when used alongside official navigational charts, can help to ensure the safety of ships, crew and cargo.
General security advice, self-protective measures, security procedures and regional contacts, as well as routeing and reporting requirements implemented by military or security forces.
Weekly updates and new editions to help maintain high levels of accuracy and safety. Guides also include ADMIRALTY QR codes for quick access to a list of all Notices to Mariners (NMs) that affect the specific chart or publication.
Maritime Security Charts should be kept up-to-date with the latest security-critical navigational information. The Security Related Information to Mariners (SRIM) service provides all of the data you need to maintain your charts from official government sources.
