Electronic chart display and information system (ECDIS)


The Electronic Chart Display and Information System (ECDIS) is one of the greatest changes in marine navigation since the introduction of radar.


On 1 July 2012, the International Maritime Organization (IMO) changed chart carriage requirements for certain kinds of ships on international voyages. These changes meant that ships can now carry ECDIS and ENC’s to meet the chart carriage requirement of the SOLAS Convention.

By 1 July 2018, almost all vessels on international voyages will be required to carry an approved ECDIS.
AMSA’s Marine Notice 8/ 2016 offers guidance on ECDIS for ships calling at Australian ports and draws attention to the latest IMO Guidance on the use of ECDIS (MSC.1/Circ.1503). Both documents can be found at the links below.

AMSA has also developed answers to some Frequently Asked Questions (FAQs) on ECDIS, which provide additional information on regulatory, charting, software and training issues pertaining to the carriage and use of ECDIS. The FAQ’s sheet can be accessed below.

Two flow charts outline potential implementation and operational issues with ECDIS. These flow charts assist AMSA’s PSC inspectors when assessing the carriage and use of ECDIS on board ships.
