Introduction to AIS
2 Chapter 1: Introduction 98-135323-H
AIS enables the automatic exchange of shipboard information from the vessel's
sensors (dynamic data), as well as manually entered static and voyage related
data, between one vessel and another and between a vessel and a shore
station(s). AIS also provides the possibility to send short safety related text
messaging for ship or shore personnel. AIS devices are required internationally
on most commercial vessels as identified by the International Maritime
Organization (IMO) in the Safety of Life at Sea Convention (SOLAS), Chapter V.
In addition, AIS is often required domestically on other vessels by some
administrations.
AIS applications and purpose
The principal applications of AIS are:
• Information exchange between vessels within VHF range of each other,
increasing situation awareness.
• Information exchange between a vessel and a shore station, such as a Vessel
Traffic Service (VTS), to improve traffic management in congested
waterways.
• Automatic reporting in areas of mandatory and voluntary reporting.
• Exchange of safety related information between vessels and between vessels
and shore station(s).
The purpose of AIS is to improve the safety of navigation and protection of the
environment by assisting in the effective navigation of ships and the operation
of VTS. This is achieved through the following:
• In a ship-to-ship mode for collision avoidance.
• As a means for littoral states to obtain information about a ship and its cargo.
• As a VTS tool, i.e. ship-to-shore, for traffic management.
• Increased situational awareness which enables effective response to
emergencies such as search and rescue (SAR) as well as environmental
pollution.
• Providing data to identify trends or improvements to enhance navigational
safety.
Note
Not all ships are required to have AIS. Furthermore, AIS may be
switched off if there is a potential risk that the operation of AIS might
compromise the safety or security of the ship, or if security incidents
are imminent.
