  • A Major Control Action (MCA) occurs when a vessel is detained, denied entry, or expelled for violating the International Ship and Port Facility Security Code (ISPS) or the Maritime Transportation Security Act of 2002 (MTSA). In 2006, the overall Flag State performance improved in terms of MCAs, decreasing from 51 to 35, and the rolling average control action ratio, decreasing from 0.89% to 0.80%. The Panamanian, Liberian, and Bahamian flags had the most MCAs. However, their rolling average control action ratios were slightly above average—Panama, or below average—Liberia and the Bahamas. Eighteen Flag States had one or more MCAs.
