Ensuring safety at sea is a top priority for every maritime fleet. The SSAS (Ship Security Alert System) and LRIT (Long-Range Identification and Tracking) systems are key components that enhance the safety of ships and their crews. In this article, we’ll explore these systems’ details, configuration, functionalities, and testing procedures. Examples of devices like the SAILOR 6120 SSA System and Iridium LT-3100S will help you understand how these advanced technologies operate.

What is SSAS?

The Ship Security Alert System (SSAS) is a technology designed for discreet and rapid reporting of threats such as piracy, hijacking, or other emergencies. Its implementation is mandatory under the SOLAS convention, and the system must be properly configured during installation.

Key Features of SSAS:

  • Simplicity: Sending an alert requires pressing just one button.
  • Discretion: The alert signal does not trigger any audible or visible alarms on the ship to avoid alerting potential attackers.
  • Integration Capability: SSAS can be part of an existing system, such as Mini-C, or function as a standalone device.
  • Hidden Antenna: Standalone systems often have their antennas installed in hard-to-reach places, such as the ship’s funnel, to ensure discretion.

SSAS Configuration

During installation, the SSAS must be configured to meet the requirements of the vessel’s flag administration. Configuration includes:

  • Vessel data such as name, IMO number, MMSI, and CSO details.
  • Recipient contact details, such as email addresses, phone numbers (SMS), or fax numbers.
  • Predefined alert message content.

SSAS Buttons – Features and Operation

A standard SSAS system includes:

  • Two alert buttons (red): One is typically located on the bridge and the other in the captain’s cabin. Once pressed, these buttons stay engaged, confirming that the alert has been sent.
  • One test button (green): This is a momentary button used for system testing without triggering an alert.

Additional alert buttons can be installed in strategic locations such as the engine control room, mess, ship’s and cargo office, or citadel.

Activating an Alert in an Emergency:

  • Press the red button. The alert will be sent after 30 seconds if the button remains pressed. Releasing the button within 30 seconds cancels the alert. Keep the button pressed until the threat has subsided.
  • The system sends alert messages to configured recipients every 10 to 60 minutes (depending on the device type and its configuration).
  • To stop the alerts, release the red button.

Testing the System with the SAILOR 6120:

  1. Ensure the green button is lit steadily—this indicates the system is operational.
  2. Press and hold the green test button. If its light goes off, no red buttons are pressed. If it blinks, one or more red buttons are engaged.
  3. While holding the green button, press a red button for 30–33 seconds. A test alert will be sent to all recipients configured for test messages.
  4. Release the red button first, then the green button.
  5. Verify successful testing with one of the alert message recipients.

SSAS Test Message

NOTE: Before conducting a test, inform your CSO—flag administration or other authorities may need to be notified about the planned test.

What is LRIT?

The Long-Range Identification and Tracking (LRIT) system allows ships to be identified and tracked over long distances. It provides information about the ship’s position, course, and speed to onshore authorities when the vessel is out of range of shore-based AIS stations, such as Marine Traffic. The system is required for most maritime vessels under the SOLAS convention.

Key Functions of LRIT:

  • Automatic Reports: The system transmits location information at least four times daily.
  • Regulatory Compliance: LRIT ensures compliance with flag administration and other international regulations.

LRIT Conformance Test

The LRIT Conformance Test is a mandatory procedure to confirm the system’s proper operation. Here are the steps:

  1. Connect the System: Use a terminal like the SAILOR 6130 to establish a connection with the satellite network.
  2. Submit a Test Request: Contact an authorized testing provider, such as Pole Star.
  3. Conduct the Test: The testing provider will perform the test automatically over 24 hours without your intervention. Ensure uninterrupted power to the system and that the antenna signal is not obstructed (e.g., by cranes).
  4. Obtain a Certificate: After successful completion, you’ll receive an LRIT Conformance Certificate valid for five years (unless the system is modified).

Summary

SSAS and LRIT systems are indispensable elements of modern maritime safety. Regular testing, proper configuration, and crew training are key to their reliability. By utilizing advanced technologies such as the SAILOR 6120 or Iridium LT-3100S, you can ensure your fleet meets the highest safety standards and complies with international regulations.
