ISPS 

The International Maritime Organization (IMO) states that "The International Ship and Port Facility Security Code (ISPS Code) is a comprehensive set of measures to enhance the security of ships and port facilities, developed in response to the perceived threats to ships and port facilities in the wake of the 9/11 attacks in the United States" (IMO).
Development and implementation were sped up drastically in reaction to the September 11, 2001 attacks and the bombing of the French oil tanker Limburg. The U.S. Coast Guard, as the lead agency in the United States delegation to the IMO, advocated for the measure.[1] The Code was agreed at a meeting of the 108 signatories to the SOLAS convention in London in December 2002. The measures agreed under the Code were brought into force on July 1, 2004.
