Is your ECDIS working? IHO Data Checks.

In Seaways (January 2012) we published an article on the IHO identification of anomalies in the way ECDIS displays data. The IHO issued a test set of data with two Electronic Navigational Chart (ENC) cells and five tests to allow the Master to see whether software is up to date and conforms to latest ECDIS standards for displaying chart data.

The IHO have advised that, as of end of January 2012, some 360 completed tests have been received by IHO. The reports received only reported on 15 of the 25 or 26 manufacturers of ECDIS. Despite this relatively low number of responses, all had indicated that some of the anomalies were present on all installed systems tested and no check failed in every system.We should all be concerned at the number of reports of systems which had shortcomings.
Owners, managers, ship operators and ship’s officers should ensure that they complete the IHO datachecks on their ECDIS/ECS and report back to IHO. If you have not yet received the check data it can be downloaded from the IHO website under Newslinks
