Answers to ECDIS questions

An Electronic Chart Display and Information System (ECDIS) is a geographic information system used for nautical navigation that complies with International Maritime Organization (IMO) regulations as an alternative to paper nautical charts. ECDIS is designed to enhance the safety of navigation by presenting a clearer, more accurate and up-to-date picture of what’s happening in the surrounding area.

The Electronic Chart Display and Information System (ECDIS) is an Electronic chart system that has been developed for vessel traffic services as well as nautical use. The primary objective of this Electronic chart display and information system is on providing navigational data with high relevance to safe navigation through a graphical interface. It also provides other features such as search functions, route plotting, alarms and monitoring facilities.

A major feature provided by ECDIS which distinguishes it from paper charts or any other traditional Electronic charting systems was its ability to present detailed information about nearshore areas.

What are the elements of Ecdis?

The major elements that compose an ECDIS are the computer system (including all essential hardware to make it work), a display, software and, of course, IMO compliant electronic navigation charts. For an ECDIS to be considered an ECDIS, it needs to be installed according to the standards and regulations set by the IMO.

The Electronic Chart Display and Information System (ECDIS) is a geographic information system that includes charts, which comply with International Maritime Organization regulations as an alternative to paper nautical charts. It provides for plotting, alarms and monitoring facilities needed by the navigator at sea in compliance with IMO resolutions A.694(16). This type of charting is not just limited to coastal navigation or inland waterway navigation but also extends offshore into territorial waters. An ECDIS can be installed on board any vessel above 150 tons carrying oil products (or other harmful substances), complying with both SOLAS 74/78 and MARPOL 73/78 conventions or it could be fitted only as bridge equipment on fishing vessels currently over 100 GRT according to FAO.

What is Ecdis function?

The Electronic Chart Display and Information System (ECDIS) is a geographic information system that has been developed to enhance the efficiency of navigation. It consists of an integrated computer system with display, software and electronic charts for marine use. ECDIS provides navigators with graphical views of the environment around them in real time, including terrestrial features such as coastline, lights on land and buoys at sea; nautical features like depth soundings; current flows; currents profiles ; water depths or other data from sensors mounted on vessels  or buoys. Electronic Charts are documents containing graphic representations and textual descriptions of physical features which show hydrographic characteristics according to set standards so that they can be used safely by mariners under normal conditions.

Is Ecdis mandatory?

ECDIS is not mandatory for a vessel navigating in the territorial sea of any State Party. ECDIS may be voluntarily installed on vessels operating within 15 nautical miles (NM) of the baseline from which the breadth of its territorial sea is measured or if it navigates in coastal waters and ports, as well as inland waterways that connect with an ocean or other large water body where such installation has been deemed necessary by the competent authority. Electronic charts are documents containing graphic representations and textual descriptions of physical features which show hydrographic characteristics according to set standards so that they can be used safely by mariners under normal conditions. Electronic Charts are documents containing graphic representations and textual descriptions of physical features which show hydrographic characteristics according to set standards

Recognizing the advantages of Electronic Chart Display and Information System, or ECDIS for navigation, in 2009, IMO adopted further amendments to regulation V/19 that would make  mandatory  the carriage of a system aboard every vessel with automatic identification systems (AIS) and which operates outside the boundary line. The amendment entered into force on 1 January 2011 making ECDIS mandatory for new ships built after set dates as well as phasing-in the requirement for existing vessels.

Training needed to use ECDIS?

The Electronic Chart Display and Information System (ECDIS) is an electronic system which provides nautical pilots with information on navigational hazards, such as shorelines or wrecks. The ECDIS replaced the paper charts that used to be a mainstay in marine navigation  with digital displays of detailed maps containing large amounts of data for ships traveling the high seas. One notable feature of this new technology was its ability to display hydrographic characteristics according to set standards so that one could easily see whether a body of water had any shallow areas before entering it. This helped eliminate some potentially dangerous situations onboard vessels where captains did not know the depth of certain regions they were passing through prior to entry into those waters.

What is Ecdis training?

This 40-hour Electronic Chart Display and Information Systems (ECDIS) program (MITPMI-179) is designed to enhance the safety of navigation by providing knowledge and skills necessary for using ECDIS. We use living marine equipment, networked with interactive blind bridge simulators.

Is ECDIS used on yacht?

The Electronic Chart Display and Information System (ECDIS) has been steadily introduced to the yachting industry over a number of years. Many see ECDIS as a system that originated in commercial vessels and was imposed on the largest of superyachts, but it is a tool that can help run smaller super yachts more efficiently.
