Marine LRIT Conformance Testing & SSAS Security Alert Systems: SOLAS V/19-1 & XI-2 Compliance

1. SOLAS Chapters V/19-1 & XI-2/6 Statutory Security Framework

Under international maritime security and safety regulations, commercial vessels must maintain two critical long-range satellite security and tracking systems:

• Long-Range Identification and Tracking (LRIT): Mandated by SOLAS Chapter V Regulation 19-1 for all passenger ships, cargo ships ≥300 GT, and mobile offshore drilling units. LRIT automatically transmits the ship’s identity, position, date, and time every 6 hours to designated Flag State Data Centres worldwide.
• Ship Security Alert System (SSAS): Mandated by SOLAS Chapter XI-2 Regulation 6 and the ISPS Code. SSAS provides covert distress signalling during piracy, terrorist, or security incidents without generating any audible or visual alerts on board.

2. LRIT Conformance Testing & Authorized Application Service Providers (ASPs)

Vessels must possess a valid LRIT Conformance Test Report (CTR) issued by an Authorized Testing ASP (such as Pole Star, Fulcrum, or CLS) on behalf of the vessel’s Flag Administration. During annual surveys or flag changes, an end-to-end satellite poll test verifies that the terminal (typically an approved Inmarsat-C, Mini-C, or Iridium unit) automatically responds to remote polling commands and position requests without crew intervention.

3. SSAS Covert Switch Verification & Security Routing

SSAS systems require at least two dedicated, covert activation push-buttons: one located on the navigation bridge and at least one other located in an alternative discreet location (e.g. Master’s cabin, engine room, or steering flat). When latched, the SSAS unit immediately transmits covert satellite distress alerts to the Flag State Maritime Rescue Coordination Centre (MRCC) and designated Company Security Officers (CSO).
