Procedures for introduction and familiarization of ECDIS -Cargo ships guideline

The introduction of any new bridge equipment has potential for risk during the transitional phase whilst navigating officers and masters become properly accustomed and experienced in its use. Radar was an example of this and brought about a number of what were termed ‘radar assisted collisions’.

ECDIS, and the switch from conventional paper charts,is probably the most significant change ever experienced within the industry and will undoubtedly bring a period of increased risk.

Electronic chart display and information system (ECDIS)

– The newly developed navigational tool using digital charts (vectorised and raster charts) for navigational tasks normally carried out with paper charts. The equipment must be type-approved and uses up-to-date official charts. As long as the area covered by vector charts (ENC) is small, the ecdis should be able to cover both vector and raster (RNC) charts. When operating in raster mode, an ecdis must be used together with an appropriate folio of up-to-date paper charts.

North up/heads capability of ecdis:

In the normal north up mode the ship moves across the static chart until it approaches the edge of the screen when a new section of the chart is automatically displayed. In heads up the vessel remains in the center of the display while the chart moves underneath. The vessel always appears up on the display with the image automatically rotated to the correct orientation, thereby matching the scene outside the window.

Radar overlay

– A navigation system which superimposes live radar video output over ecdis. It provides a scan-converted output for display, automatically scaled to suit the displayed chart. The transparency can be adjusted so that the chart can be seen through the radar image. The overlay and its controls conform to ecdis standard for combining radar with ecdis chart display.

Electronic navigational chart (ENC),

also vectorised chart – Vector charts made up of layers which can be displayed selectively. Each point on the chart is digitally mapped, allowing information to be used in a more detailed way, such as clicking on a feature to display its information. Vector charts have the advantage of being “interactive”. For instance, the operator can pre-set the vessel draught and a ˝ mile exclusion zone. At any time when the vessel is within ˝ mile of an area of shallow water, an alarm activates. Chart data can be shared with other equipment such as arpa and radar. There are various chart formats. Hydrographic offices are responsible for the production and accuracy of the ENC material.



Electronic Chart Display and Information Systems (ECDIS) is ship borne navigational equipment, which is regarded as an equivalent to paper charts as per the SOLAS regulations. Currently its carriage is optional however the introduction of the new Amendments to SOLAS regulations make the carriage of Electronic Chart Display and Information Systems (ECDIS) mandatory under SOLAS chapter V, Safety of Navigation in a phased manner.

When a vessel is fitted with ECDIS in accordance with the mandatory requirements and is certified, then the ECDIS will be allowed as the primary means of navigation for that part of the voyage where vessel has Vector chart display system (VCDS) and paper charts need not be used.

To ensure compliance with the ECDIS requirement, to ensure that the transition is smooth, equipment installed and Master and Bridge watch keepers are all provided generic and ship-specific ECDIS equipment training before the implementation dates of various type vessel: ECDIS Training Requirements

Master and Navigating Officers of vessels which have ECDIS as their primary means of navigation must be fully familiar with the operation of the ECDIS prior to the first voyage after installation of ECDIS. The Master and all Navigational Officers of vessels, which have ECDIS as their primary means of navigation, are required to have completed both generic and ship specific equipment ECDIS training. Onboard vessels fitted with ECDIS, Masters are to ensure that all deck officers onboard are familiar with the operation of ECDIS together with its limitations, this shall be recorded.

ECDIS Generic Training

The completion of an ECDIS programme based on the IMO Model ECDIS course (1.27) approved by any national maritime authority will be recognized as meeting the ECDIS generic training requirements. This will mitigate the risk of a navigation incident through unfamiliarity with ECDIS and e-navigation principles in general.

ECDIS Type Specific Training

To mitigate the risk posed by the introduction of ECDIS the industry expect all deck officers to complete a manufacturer-approved familiarisation course in order to bridge any gaps between the IMO 1.27 course and the specific equipment installed on their assigned vessel. This type-specific familiarization training must be completed prior to the officer taking his/her first navigational watch onboard.

Where the Officer completed his/her IMO 1.27 course on the same make of equipment as fitted onboard, this is deemed sufficient to cover both the generic and type-specific training needs provided the ECDIS equipment make / model is recorded on the training certificate.

ECDIS manufacturers provide different forms of type specific training. This ranges from CBT training to training courses provided at the manufacturers own facility. The convenience and cost of the various types of manufacturer training therefore varies greatly and will require varying levels of planning and organisation.

ECDIS Vessel Specific Training

For all vessels fitted with ECDIS, joining masters and deck officers must continue to undergo ship specific equipment familiarisation .

ECDIS Company Specific Training

For all vessels fitted with ECDIS, company should develop an in-house ECDIS course to supplement the IMO 1.27 course, which will focus on minimum standards, an explanation of ECDIS use and best practice procedures that must be used by all masters and deck officers when navigating using ECDIS.

ECDIS warning procedure
Although many vessels have fitted Electronic Chart Display and Information Systems (ECDIS) on a voluntary basis, its use will significantly increase once passenger vessels, tankers and dry cargo ships begin to comply with mandatory SOLAS requirements for ECDIS.

Admiralty Chart correction procedure
There are currently two methods of carrying out electronic chart corrections, either via Weekly Updates, CD or downloaded weekly from a recognised electronic chart supplier’s data. The preferred method will be decided by the Management Office depending on the communications equipment onboard the vessel but in the majority of cases the lack of internet access will determine the update CD as the best option....
