Guidelines on annual testing of the automatic indentification system(AIS)

  1. The Maritime Safety Committee, at its eighty-third session (3-12 October 2007), approved the Guidelines on annual testing of the Automatic Identification System (AIS) developed by the Sub-Committee on Flag State Implementation, as set out in the annex.

  2. The purpose of an annual testing is to determine that AIS is operational as defined in appropriate performance standards not inferior to those adopted by the Organization*.

  3. To assist in achieving this aim, it is recommended that all AIS be subject to a standard
    method of testing as detailed in the annexed Guidelines.

  4. Member Governments are invited to bring these Guidelines to the attention of shipping companies, shipowners, ship operators, equipment manufacturers, recognized organizations, shipmasters and all parties concerned. 

* . Refer to Recommendation on performance standards for a universal shipborne automatic identification system (AIS) (resolution MSC.74(69), annex 4).

Guidelines on annual testing of the automatic indentification system(AIS)

  1. The annual testing of the automatic identification system (AIS) should be carried out by a qualified radio inspector authorized by the administration or a recognized organization.
  2. The annual testing of the AIS installation should include:
    1. installation details including antenna layout, initial configuration report, interconnection diagrams, provision of the pilot plug and power supply arrangements;
    2. checking the correct programming of the ships static information;
    3. the ability of the AIS to receive ships dynamic information from the appropriate sensors;
    4. the ability to correctly input the ships voyage related data;
    5. a performance test of the equipment including radio frequency measurements; and
    6. an on-air test that the unit is working correctly using for example an appropriate Vessel Traffic Service (VTS) station or a suitable test equipment.
  3. To accommodate performance test to align with the appropriate survey under the Harmonized System of Survey and Certification (HSSC), the annual testing may be carried out:
    1. up to 3 months before the due date of the passenger ship renewal survey or the cargo ship safety equipment renewal survey; and
    2. 3 months before or after the due date of the cargo ship safety equipment periodical/annual survey (the maximum period between subsequent test is governed by the time window associated to the subsequent surveys, unless either certificate has been extended as permitted by SOLAS regulation I/14, in which case a similar extension may be granted by the Administration).
  4. The annual testing should be recorded in the form of the model test report given in the appendix. If the language used is neither English, nor French, nor Spanish, the text should include a translation into one of these languages. A copy of the test report should be retained on board the ship.
