1 General

 The Automatic Identification System (AIS) Class A is defined by IMO and has been made a carriage requirement by the latest revision of SOLAS chapter V. AIS provides information that may be used for the navigation of the ship. It is therefore essential that the information provided by AIS be reliable.

The AIS itself has been standardised by the International Telecommunications Union (ITU) and the International Electrotechnical Commission (IEC) and is subject to type approval. In order to fulfil the reliability requirements of information exchange, care should be taken to ensure that the AIS is correctly installed.

This document contains guidelines for manufacturers, installers, yards, suppliers and ship surveyors. It does not replace documentation supplied by the manufacturer.

The guidelines take into account the following conventions, regulations, instructions and guidelines:

  • IMO resolution MSC.99(73) Annex 7, Adoption of amendments to the International Convention for the Safety of Life at Sea, 1974, as amended.
  • IMO resolution MSC.74(69) Annex 3, Recommendation on performance standards for AIS.
  • ITU Radio Regulations (RR).
  • IEC 60092 (series), Electrical Installations on Ships.
  • IEC 60533 Electrical and Electronic Installations in Ships - Electromagnetic Compatibility.
