Technical Standards for ECDIS 

The number one complaint from mariners on ECDIS was the number of alarms generated. The IHO has taken this on board with the latest Presentation Library (version 4.0) which addresses this issue. Also, information such as fairway and anchorage area names now appear on screen, with landmarks, lights and buoys viewable via a ‘hover-over’ function. This reduces the constant need to find information buried in a pick report.

Read the Admiralty Blog "The new S-52 ECDIS Standards: What do they mean for you?" by Tom Mellor, Head of OEM Support and Digital Standards.

The new ECDIS testing standard publication date is expected to be Aug 15th. From this date the new edition of S-52 will be the reference for the type approval of new ECDIS. Existing ECDIS will have to be upgraded to the latest Presentation Library within twelve months.

Users new to an ECDIS-installed ship should check that sufficient knowledge of items on the familiarisation check list is obtained before using the ECDIS and its back-up at sea. If use is to be made of the RCDS Mode, any differences in operational procedures should also be understood. Items in the list have been identified with a W or an M.
Although users of ECDIS should have an understanding of all items marked W and M, the priority for a watch-keeping officer is to become fully familiar with all items marked W. For those users who are responsible for voyage planning and other ECDIS management activities, items marked W and M have equal priority.

ECDIS Feedback

The Manila Amendments to STCW (which include the use of ECDIS to maintain the safety of navigation as a required competence) came into force on 1st January 2012 and the mandatory carriage of ECDIS began to phase in from 1st July 2012. Over the next 5 years, as more mariners gain experience in using new equipment and technology associated with electronic navigation, there will be many issues arising from this increasing use of ECDIS. The Nautical Institute would like to hear from you on any relevant issues you have experienced in using ECDIS.

Issues may be directly related to the use of equipment and its navigational facilities, including whether information is being appropriately displayed. Other issues may address aspects of the current operational practice of using ECDIS and some may arise solely from insufficient or inappropriate training of users.

The long term aim of this initiative is to improve the design of ECDIS equipment and its data by influencing regulations and standards and also to influence the way in which the use of ECDIS is taught to and used by seafarers.

The Nautical Institute's Technical Committee has arranged to collate any reported issues and submit them to the appropriate bodies including:

• The International Hydrographic Organization (IHO)
• The International Electrotechnical Commission (IEC)
• The International Association of Marine Electronics Companies (CIRM)
• The IMO

This forum also contains links to useful information for mariners, including casualty reports where ECDIS or ECS has been found to be a contributory factor. (Dates are the date of the investigation report.)
