New VDR standards mandated
This month has seen more stringent nav chart data demanded from voyage data recorders (VDR).
The new IMO VDR Performance Standard - MSC.333 (90) - came into force on 1 July. This demands that VDR installations must:
- include the ability to capture ECDIS screenshots at least every 15 seconds
- record the charts in use at least every 10 minutes
- record all changes of chart
In detail, the mandate states:
'Where a vessel is fitted with an ECDIS installation, the VDR should record the electronic signals of the ECDIS display in use at the time as the primary means of navigation. The recording method should be such that, on playback, it is possible to present a faithful replica of the entire ECDIS display that was on view at the time of recording, albeit within the limitations of any bandwidth compression techniques that are essential to the working of the VDR, and in addition the source of the chart data and the version used.'
Hence ECDIS manufacturers now have to enable the appropriate outputs from the ECDIS. And, to take an example, PC Maritime have completed this work in accordance with the appropriate IEC 61996-1 and 61162-450 specifications - so their Navmaster ECDIS is now compatible with all VDR units conforming to the new standards.
PC Maritime add that ECDIS upgrades are free to subscribers and sent direct to ships via email - and can be installed by crews, with no need for an engineer visit.
