Who has the authority to raise the MARSEC level?

The authority to raise the MARSEC (Maritime Security) level lies with the Captain of the Port (COTP). The COTP is designated by the U.S. Coast Guard and plays a crucial role in ensuring maritime security within their area of responsibility. The COTP considers various factors such as threat assessments, intelligence reports, and situational awareness when deciding whether to raise the MARSEC level. This authority is based on the need to provide a coordinated and consistent approach to maritime security operations, especially in response to potential threats or vulnerabilities.

While other stakeholders, such as facility operators, USCG District Commanders, and port authorities, may play significant roles in security planning and response, the COTP maintains the specific authority to formally change the MARSEC level. This hierarchical structure is essential for effective communication and implementation of security measures across affected facilities and waterways.
