The Ship Security Alert System (SSAS) is part of the ISPS code and is a system that contributes to the International Maritime Organization's (IMO)'s efforts to strengthen maritime security and suppress acts of terrorism and piracy against shipping.[1] The system is an IMO regulated system. In case of attempted piracy or terrorism, the ship's SSAS beacon can be activated, and appropriate law-enforcement or military forces can be dispatched. An SSAS beacon operates with similar principles to the aircraft transponder emergency code 7700.
