What is ECDIS?

ECDIS formally stands for Electronic Chart Display and Information System, offering digital charts and navigational information so that seafarers can plan their routes much better and monitor where they are going.

Are you ECDIS compliant?

ECDIS is defined in the IMO ECDIS Performance Standards (IMO Resolution A.817(19)) as follows:

‘Electronic Chart Display and Information System (ECDIS) means a navigation information system which, with adequate backup arrangements, can be accepted as complying with the up-to-date chart required by regulation V/19 & V/27 of the 1974 SOLAS Convention, by displaying selected information from navigation sensors to assist the mariner in route planning and route monitoring, and by displaying additional navigation-related information if required.’

With just one initial upfront cost, all your navigation needs are met within Admiralty’s ECDIS.

What is a nautical chart?

These are maps that look specifically at marine navigation. This could be anything from depth of water, elevations, coastlines, potential dangers, the nature of the bottom of seabeds, and aids.

The law states that all ships going on international voyages must carry nautical charts of some kind on board.

This can be in paper or electronic form, and only those greenlit by a government can be deemed as official. All official charts are split into two types: RNC, which is a scanned image of a paper chart, and ENC that can be manipulated by the user to show information about specific areas.

Do the charts get updated?

ECDIS gets updated regularly with new chart information – this comes in the form on online downloadable content. You need to make sure the information is always up-to-date, or you will be at risk at sailing on old visuals.

What does the International Maritime Organisation (IMO) say about ECDIS?

The IMO states that all vessels must, by law, carry ECDIS after a certain date, depending on what type of ship you own. The general implementation period will run from 2012 to 2018, but this is the specific schedule, based on ship type:

  • Newbuild passenger ships (over 500 GT) and tankers (over 3,000 GT) – July 2012
  • Newbuild cargo ships (over 10,000 GT) – July 2013
  • Newbuild cargo vessels (between 3,000 and 10,000 GT) and existing passenger ships (over 500 GT)  – July 2014
  • Existing tankers (over 3,000 GT) – July 2015
  • Existing cargo ships (over 50,000 GT) – July 2016
  • Existing cargo ships (between 20,000 and 50,000 GT) – July 2017
  • Existing cargo ships (between 10,000 and 20,000 GT) – July 2018

What other acronyms do I need to know?

A few to consider are:

  • ENC – Electronic Navigation Chart (the database containing the chart data)
  • SENC – System Electronic Navigation Chart (after the ENC data has be converted for chart image creation on the ECDIS)
  • RCDS – Raster Chart Display System (when ENC is not available, a vessel can sail in this mode if the flag state says so)
