Overview

ADMIRALTY Maritime Security Charts (MSCs) contain safety-critical information for situational awareness and to assist bridge teams in the planning of safe passages through areas of risk.

Body

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.​

​​​​​Each Maritime Security Chart includes:

  • Information about dangers to the security of navigation including piracy, terrorism, embargoes, mine warfare, exclusion zones, blockades, illegal unreported and unregulated fishing, smuggling and GPS jamming and spoofing. This information, when used in conjunction with official navigational charts, can help towards enhancing the safety of ships, the crew and cargo.
  • General security advice, self-protective measures, security procedures and emergency and regional safety contacts, as well as routeing and reporting requirements implemented by the military or regional authorities.
  • Regular updates of SRIMs and when required, new editions of Maritime Security Charts (MSCs) to help maintain the flow of security related information to enhance situational awareness and general safety.

Emergency contact details and maritime security points of contact

Body

The regional Emergency Contact authority details are included and highlighted on the MSCs, these are normally the primary providers of maritime security information to ships that are transiting High-Risk Areas (HRAs) or areas of perceived risk. These centres also receive reports from shipping transiting Voluntary Reporting Areas (VRA) or those involved in Maritime Security related incidents. These centres provide the information flow between the Military and the international shipping community. In addition, a Maritime Security Points of Contact list is included with recommendations of those authorities and personnel who should be contacted once the emergency call is completed. 

Examples are:

United Kingdom Maritime Trade Operations (UKMTO) centre located in Dubai, is often the primary point of contact for merchant shipping involved in maritime security issues in the Indian Ocean region, particularly the HRA. The UKMTO operates the VRA as illustrated on UKHO MSC Q6099.

NATO Shipping Centre (NSC) is responsible for Operation Sea Guardian which is a maritime security operation in the Mediterranean Sea, the Strait of Gibraltar and approaches (outside the territorial waters of regional nations). NATO encourages commercial shipping entering and transiting this geographical area to take part in the Mediterranean Voluntary Reporting Scheme (MVRS) as depicted on UKHO MSC Q6110.

Updates

​​Maritime Security Charts should be kept up-to-date with the latest security-critical navigational information.

The Security Related Information to Mariners service combined with Notices to Mariners provides all of the data you need to maintain your charts.​​
