Maritime Terms, Abbreviations and Acronyms

Maritime abbreviations and acronyms go back to those days we used telegram and telex to communicate. The business model for telex and telegrams was “pay per letter”. Even though the telegrams and telexes have been retired, we still use the maritime abbreviations daily.

Below you will find a comprehensive list of terms, abbreviations, and acronyms used in the maritime industry, sorted in alphabetical order. You can search for an acronym or write a word and find the abbreviations where the word is included.

If you think some abbreviations are missing, send us an e-mail at post@maritimeoptima.com or open the chat icon on the bottom of this page.

ECD

Electronic Chart Display

ECDIC

Electronic Chart Display and Information System. Electronic Chart Display and Information System - An ECDIS is a ship borne electronic navigational device designed to display digital nautical charts that is tested and type-approved to international standards and may be used, in conjunction with appropriate ENCs and backup arragements, as a means of primary navigation. The use of ENCs in a type-approved ECDIS and with appropriate back up arrangements, is the only paperless chart option for SOLAS vessel navigation. All ECDIS systems are required to be able to load and display digital nautical charts in standard S-57/S-63 format, and some systems may also accept data in a proprietary SENC format. In addition, an ECDIS is only an ECDIS, when it is using official electronic nautical charts (ENCs) that have been produced by an authorised body, such as a hydrographic office. The use of an ECDIS in conjunction with ENCs and appropriate back up arrangements, is the only legal option for so-called paperless navigation.

Electronic Chart System

ECS

Electronic Chart System - An ECS is any ship borne electronic navigational device that is designed to display digital nautical charts but is not tested and type-approved as an ECDIS. An ECS may be used as an aide to navigation by a SOLAS vessels but cannot be used as a primary means of navigation or to satisfy SOLAS chart carriage requirements. ECS system are widely used in non-SOLAS applications and as they are not type-approved they can incorporate special features that meet particular application requirements, such as portable pilot units. Many ECS systems use proprietary chart data formats and do not accept digital chart data in standard S-57/S-63 or dENC format.
