Step 3. Choosing the correct ECDIS fit

There is a large range of ECDIS equipment available, from those that are part of an integrated bridge system, through to small standalone units that could be more appropriate for retrofit to vessels that have limited bridge space.

The IMO standards require that vessels must carry a backup to ECDIS that can take over the chart-based navigation functions in event of system failure. The fitting of a second ECDIS or the carriage of paper charts are widely accepted as back-up that will meet requirements. Depending on your Flag State, other solutions such as the carriage of a Chart Radar or other type-approved electronic back-up may be accepted.

You will need to decide whether to fit vessels with single or dual ECDIS systems. Fitting a dual system will allow a significant reduction in the paper charts carried (in some cases down to zero). If using paper charts as a back-up to a single ECDIS you are likely to require the carriage of a full (or only slightly reduced) folio.

However you intend to install and operate with ECDIS, you will need to work closely with the Maritime Authority that your vessels are registered with to ensure you comply with all the requirements.

For a list of Flag State back-up requirements, you can also refer to the Compendium of Flag State ECDIS requirements at www.ukho.gov.uk/2012compliance

Dual or Single ECDIS
  • Dual — reduce the requirement for paper charts
  • Single — carry and maintain existing paper charts
