Which entity is most likely to conduct Port State Control inspections?

The Coast Guard is the entity most likely to conduct Port State Control inspections because it is specifically mandated to enforce maritime laws and safety regulations under international agreements, such as the International Maritime Organization's conventions. Port State Control is focused on ensuring that foreign-flagged vessels comply with safety, environmental, and labor standards as set by international treaties and conventions. The Coast Guard has the authority and expertise to perform these inspections, assess compliance, and take enforcement actions if necessary.

Other entities, such as the Environmental Protection Agency, have distinct roles primarily centered around environmental regulations, while the Navy's primary mission is military operations rather than the enforcement of maritime safety standards. Port Authorities may have some regulatory roles, particularly regarding local port operations, but they do not possess the same level of authority or focus on global maritime safety and security as the Coast Guard.
