2 Data Maintenance of the Electronic Charts
2.1 General
The electronic charts for your NACOS Platinum System are stored separately on each MFD (workstation).
They have to be updated in regular intervals.
After initial installation from the base media the charts are updated typically in a weekly schedule from
the update media. During the update process the already installed charts are checked and it might be
necessary to insert the base media again if requested by the update application during the update
process
The update can be carried out for each MFD separately by using update media like CD ROM, USB-Stick,
or portable USB drive. The procedures will take some time, because the chart cells are processed on the
MFD, in case of ENC charts they are also decrypted and converted into an internal file format. This
improves the chart presentation speed during later ECDIS operation.
For practical reasons it is recommended to perform the time-consuming update from media on the ECDIS
planning system. Once this MFD has been updated, the other MFD’s in a network can be updated by a
simple and faster network action.
The initial installation can take several hours. Even an update may require a considerable length of
time. Therefore, perform this task in good time before the start of the voyage.
The chart maintenance work must be carried out so that the databases of all MFD’s always have
the same status. This is ensured if the notes given here are observed and the sequences described
are followed.
- An easily determined indication of unequal states of the databases of the MFD’s is when the
numbers of cells/ charts displayed for one MFD is different from the others.
- An update of a chart cell can only be performed if the base information for this cell has been
installed before. Also the update sequence must not be interrupted. If one update has been missed
in the past it is not possible to add a new update. In that case carry out the base update again.
