Updating charts can be done either from a CD-ROM/DVD received from the chart vendor or via satellite using an intermediate PC onboard or through a direct connection to the ECDIS through Service Gateway.
If additional charts are required they can be bought via e-mail or from the internet, while onboard.
The implementation of ECDIS installation onboard vessels will need to be type-approved and they have to issue a certificate of compliance which is used by the classification society, the port state control and vetting administration to ensure that the vessel is in full compliance with the requirement to carry type approved ECDIS with suitable back-up facilities.
In some cases you can expect that port state control or vetting administration will verify if the crew is properly trained and has a sufficient understanding of the operation of ECDIS.
Besides that ECDIS will become a mandatory system onboard vessels, the implementation and use of ECDIS provides a wide range of advantages.
It makes the voyage planning easier by allowing optimization according to time, speed and other parameters, and any modification is accomplished by a simple drag and drop action or by a click and inserting a modified value.
It gives a reason for better safety in the voyage planning by taking the ship’s draft into consideration when planning the route and combine this with dangerous areas or areas of special attention.
The charts are made and distributed by the hydrographic offices through a distribution network and the vessel has to subscribe to the chart service.
The ECDIS monitors the data received from the many navigation data sensors connected to the ECDIS and the ECDIS validates the data and emits a warning signal or alarm in case ECDIS detects that navigation data are corrupted.
In addition, the ECDIS can be preprogrammed to indicate to the navigator on watch if the vessel has reached a position or area which require special attention by the navigator or planned actions.
ENC are vector charts, which are provided in the S-57 format.
