The OOW and the ROC ARPA Certificate

The OOW should never depend on the information alone. It is only an aid to navigation and never replaces the human quotient which brings in the skill and expertise with experience that an ECDIS can never provide. The same is achieved via simulations.

Deep Contour and the Colors of Dark Matter

You can clearly see the difference between the two colors if you set Deep Contour as 200 meters.

It is not used for navigation. The paper chart is the primary means of navigation for vessels with the use of electronic charts. The training for the Navigating Officers should relate to the make and model of the equipment that is used.

The training should last at least 8 hours. All charts are pre-installed in the equipment with the base CD available, but only those with licenses have access to them.

The positions of other vessels and targets on the ECDIS might be obscured because of the improper tuning of the radar or anti-clutter on it. During the installation phase, the possibility offset error is eliminated and later can be adjusted using the administrative rights in ECDIS. Some sea areas are not covered by the charts.

The electronic chart coverage for the voyage must be adequate. It is mandatory that they be used instead of RNC for areas covered by the ENC. If RNCs are to be used, an updated paper chart for those areas will be available onboard and office will be informed prior to the passage.

Important information may not be displayed if the display has been set up correctly prior to sailing. Base, Standard and Full are the default settings for the layers of an ENC. The ENCs should be in full access mode.

The Structure and Format of Chart Data

The structure and format of the chart data, the presentation of chart data, and the encryption of chart data are all within the scope of relevant I HO standards. The chart information should be the latest edition, as corrected by official updates, of that issued by or on the authority of a Government, government-authorized Hydrographic Office or other relevant government institution. ECDIS should be able to accept updates to the data manually with simple means for verification before the final acceptance of the data.

They should be seen as separate from the official updates of the ENC and not affect display legibility. The mariner should be able to select a safety depth. Spot soundings should be emphasized equal to or less than the safety depth if they are selected for display.

It should be possible to display the information in a north-up orientation. Other orientations are allowed. The orientation should be changed in steps large enough to avoid the display of the chart information.

The method of presentation should make sure that the displayed information is visible to more than one observer in the light conditions of the bridge of the ship. 11.47 The position of the ship should be derived from a continuous positioning system that is consistent with the requirements of safe navigation.

A second independent positioning source should be provided whenever possible. ECDIS should be able to identify discrepancies between the two sources. When the input from position, heading or speed sources is lost, the ECDIS should provide an alarm.
