Overview

About Security Related Information to Mariners

ADMIRALTY Maritime Security Charts (MSCs) contain security-related information for situational awareness and to assist bridge teams in planning safe passages through areas of increased risk. All information has been gathered by the UKHO working with NATO, other government agencies and international partners, ensuring that each chart has the most accurate, up-to-date and verified information available.​​

Mariners should maintain these charts to stay up-to-date with the latest security-related navigational information. The Security Related Information to Mariners (SRIM) service provides additional data to enhance the content of the folio of MSCs as well as security-related information to assist with passage planning.

Security Related Information to Mariners is provided free of charge on this website. ​ADMIRALTY Maritime Security Planning Charts are available for purchase from official ADMIRALTY Distributors.​
