MSCI Advisory

2019-009-Global-Overview of the U.S. Maritime Advisory System


This revised advisory cancels U.S. Maritime Advisory 2019-001.

1. Reference: (a) U.S. Maritime Advisory 2017-001

2. Issue: The U.S. Maritime Advisory System is a coordinated, multi-agency U.S. Government (USG) communication mechanism involving the Departments of State, Defense, Transportation, and Homeland Security, as well as the intelligence community. This system was created to streamline, consolidate, and replace outdated agency-specific maritime threat information.

3. While the U.S. Maritime Advisory System website (, which contains all current and expired U.S. Maritime Alerts and Advisories, is maintained by the Maritime Administration (MARAD), and Alerts and Advisories are transmitted by email and broadcast by the National Geospatial-Intelligence Agency (NGA) when released, it is important to note that these are not MARAD or NGA products, but USG products.

4. With the assistance of feedback from U.S. commercial maritime stakeholders, the USG is pursuing continued enhancements to the U.S. Maritime Advisory System. Future enhancements currently under development include a more robust Advisory subscription tool, training modules, and improved means for industry to communicate threats, concerns, and needs.

5. Guidance: The U.S. Maritime Advisory System now includes a new type of U.S. Maritime Alert to relay urgent maritime related information from other USG sources or international regional maritime security reporting centers (i.e. United Kingdom Maritime Trade Operations, Maritime Domain Awareness for Trade Gulf of Guinea, Regional Cooperation Agreement on combating Piracy and Armed Robbery, International Maritime Bureau Piracy Reporting Center, etc.), when warranted. These U.S. Maritime Alerts will occasionally be utilized to publish verbatim information from the original source, which will be clearly identified, and will follow a slightly modified format.

6. The Office of Foreign Assets Control (OFAC) of the Department of the Treasury administers and enforces economic and trade sanctions based on U.S. foreign policy and national security goals against targeted foreign countries and regimes, terrorists, international narcotics traffickers, those engaged in activities related to the proliferation of weapons of mass destruction, and other threats to the national security, foreign policy or economy of the United States. In some cases, these sanctions may impact maritime trade. OFAC sanctions information and notices can be found at: Any questions relating to OFAC sanctions may be emailed to:

7. U.S. Centers for Disease Control Travel Notices may impact commercial shipping interests, especially during overseas crew changes, and can be found at: U.S. Maritime Alerts and/or Advisories may occasionally be published depending on the scope, urgency, and impact of health threats, but mariners are advised to become familiar with this web resource and refer to it prior to traveling.

8. U.S. Department of State Travel Advisories discuss safety and security information which should be reviewed by U.S. mariners prior to disembarkation in foreign ports. These travel advisories are available at:

9. The new Maritime Global Security website at offers industry issued best practices and guidance to mariners by geographic region and provides contact and subscription information for regional maritime security reporting centers, particularly in high risk-areas.

10. Those who desire to subscribe to U.S. Maritime Alerts and Advisories may do so at, which also provides additional information on the U.S. Maritime Advisory System.

11. Contact Information: Questions regarding the U.S. Maritime Advisory System may be emailed to the Global Maritime Operational Threat Response Coordination Center at Additional contact information is available on the U.S. Maritime Advisory System website listed above.

12. This message will automatically expire on December 29, 2019.
