What is an Electronic chart display system?

An electronic chart display system is a general term for all electronic equipment that is capable of displaying a vessel’s position on a chart image on a screen.

There are two classes of electronic chart display systems. The first is an ECDIS (Electronic Chart Display and Information System), which can meet IMO/SOLAS chart carriage re­quirements. The second is an ECS (Electronic Chart System), which can be used to assist navigation, but does not meet IMO/SOLAS chart carriage requirements.

ECDIS

ECDIS equipment is specified in the IMO ECDIS Performance Standards as follows:

Electronic Chart Display and Information System (ECDIS) means a navigation information system which, with adequate back up arrangements, can be accepted as complying with the up-to-date chart required by regulation V/1 9 & V/27 of the 1974 SOLAS Convention.

Where the term ECDIS is used in this document, this is to be understood as those naviga­tional electronic chart systems, which have been tested, approved and certified as com­pliant with the IMO ECDIS Performance Standards and other relevant IMO Performance Standards and thus is compliant with SOLAS ECDIS requirements.

ECS

ECS is specified in ISO 19379 as follows:

ECS is a navigation information system that electronically displays vessel position and relevant nautical chart data and information from an ECS Database on a display screen, but does not meet all the IMO requirements for ECDIS and is not intended to satisfy the SOLAS Chapter V require­ments to carry a navigational chart.

ECS equipment ranges from simple hand held GPS enabled devices to sophisticated stand­alone computer equipment interfaced to ship systems.

Where are the rules for professional marine navigation written down?

The 1974 International Convention for the Safety of Life at Sea (SOLAS 1974), subse­quently amended in 2000 and 2002, specifies the requirements for the navigational equip­ment to be used onboard ships entitled to fly the flag of a party to the convention. This Convention was adopted by the International Maritime Organisation (IMO), the United Nations Organisation that is concerned with maritime transportation.

IMO member states are obliged to adopt IMO rules and regulations into their national leg­islation. However, only when the convention text has been incorporated into national leg­islation does it take effect for the individual ships registered in that country. This process of incorporation into national legislation may vary from a few months to several years.

The country in which a ship is registered and hence which flag it is flying is known as the Flag State. It is the national maritime administration representing the Flag State, which controls the adherence to the SOLAS carriage requirements (Flag State control).

The national maritime administration is also responsible for Port State control. Ships arriv­ing at a port may be subject to Port State control by local officials (Port State Control Of­ficers – PSCOs) based on Flag State regulations and international agreements. Port states

cooperate within regions to apply consistent standards, for example the European nations and Canada cooperate under the umbrella of the Paris Memorandum of Understanding (Paris MOU).
