ENC Collection Management

This section describes the processes for managing the ENC collection in NSR ECDIS NES-3000: installing, updating ENCs, and configuring ENC display settings.

ECDIS Chart Provisioning

NSR ECDIS NES-3000 supports reading and display of ENCs in IHO S-57 format, edition 3.1. ENCs are provided by chart data providers as exchange sets, in accordance with the IHO S-63 standard, in encrypted form. NSR ECDIS NES-3000 can also install unencrypted ENCs provided they include the mandatory CATALOG.031 file.

Important

Exchange sets without the CATALOG.031 file are not supported!

Exchange sets are transmitted via Internet services (e-mail, FTP) together with X.509 root certificates and cell permits required for decrypting ENC cells. To install ENCs in ECDIS, the data must be written to a prepared USB medium.

Ordering ENCs requires a User Permit, confirming that the software manufacturer has passed the IHO S-63 standard compliance check and is a registered IHO OEM.

User Permit Location

Menu path
→ → System Information → User Permit

To avoid transmission errors, it is recommended to save the USER PERMIT as a text file on external media and send it to the provider by e-mail.

Exporting the User Permit

Menu path
→ → System Information → Select User Permit → Export

The received encrypted ENC data set contains: base ENC cells, ENC updates, external files (*.pdf, *.png, *.bmp, *.jpg, *.txt), IHO X.509 certificate (Scheme Administrator (SA) Digital Certificate), the CATALOG.031 catalogue, and cell permits. The encrypted set may be packaged in a *.zip or *.tar.gz archive.

Important

ECDIS supports installation of certificates, ENC licenses, and charts from zip and tar.gz archives written to a USB medium. Installation of data from nested archives at the second level or deeper will not be performed.

The recommended file system for the USB medium is **FAT32**.

It is NOT recommended to install ENC exchange sets from media containing large amounts of other data: ECDIS will require more time to scan all folders and archives on the medium.

Important

When installing a large ENC set (e.g., the world chart collection), the installation process may take a significant amount of time.

Installing update sets on large ENC collections may also take a considerable amount of time.

Consider these characteristics when managing the shipboard ENC collection and perform ENC installation and updates well in advance.

Installation of ENC cell permits from nested second-level archives is not performed. To install ENC cell permits, the nested files must be extracted first.

Tip

License management recommendations:

When receiving an update set for cells already installed in ECDIS, it is not recommended to reinstall the cell permits. Repeated installation of permits for the same cells will significantly slow down the ENC installation process and may eventually make it impossible to decrypt the cells.

If the error **”SSE 21”** occurs, it is recommended to delete the ENC permits from ECDIS, reinstall the ENC permits, and retry the ENC cell installation.

Removing licenses:

Menu path
→ → System → Certificates/Permits → Delete

ENC management recommendations:

• Regularly create backups of important chart sets

• Monitor the currency of installed updates

• Check license status before planning voyages

• Use the search function to quickly locate ENCs

Note

ECDIS supports operation with AIO.

ECDIS treats AIO cells as ENC cells: installation of AIO cells, updates, and removal of AIO are performed in the same way as for S-57 cells.

ENC Cell Corrections

Installing Updates

Update sets are provided by the data provider (data server). ECDIS treats update files as cells, and the installation procedure in ECDIS is identical to the **chart installation** procedure.

Update installation procedure:

1. Insert the USB medium with the data set into the ECDIS USB port

2. Menu path
   → → ENC → Find ENC → Select → Install

3. In the dialog, select from the drop-down list the name of the set into which the updates should be installed

Important

Updates can only be installed into the set for which they were issued. For example: if cells are installed in the IHO set, then updates issued for those cells must be installed into the IHO set.

Attempting to install updates into a different set will result in the installation being refused.

4. Press Install.

5. The installation result will be displayed as a notification at the bottom of the window and recorded in the Installation Log

The update installation result is recorded in the Installation Log, and information about installed updates is updated in the ENC Collection (Data Set).

UKC Management

Caution

The term “danger depth” refers exclusively to depths displayed on the electronic chart, reduced to its datum (Vertical Datum). The “danger depth” value is used by ECDIS to automatically select the “safety contour” for a vessel with given dimensions, a standard under-keel clearance margin, and a correction for the excess of the actual water level above the chart datum, and to generate appropriate warnings.

The actual depth measured by the echo sounder under specific navigational conditions will generally differ from the depths contained in the electronic chart.

Important

UKC — minimum under-keel clearance control is designed for navigation in conditions of water level fluctuations: tidal phenomena, as well as wind-driven water level variations.

UKC provides dynamic calculation of the danger depth depending on the current water level value. The water level can be obtained from various sources: tide gauge data, tide tables, ASM.

Manual Entry of Safety Contour and Safety Depth

No.	Element	Description
1	UKC Management	Select the method for entering the safety depth and safety contour. Select Disable for manual entry of the safety contour and safety depth. A warning will appear in the notification area
2	Safety contour	Manual entry of the Safety contour value. ECDIS highlights on the ENC the contour equal to the set value, or the nearest deeper contour. Monitoring is performed along the selected contour
3	Safety depth	Manual entry of the safety depth value. The safety depth is set by the navigator based on procedures adopted by the Company for the given vessel. ECDIS performs monitoring and generates warnings for depths equal to and less than the entered value
4	Water level elevation above chart datum	Manual entry of the current water level value. With manual entry of safety depth and safety contour, this is for informational purposes only
5	Duration	Duration of validity of the entered water level value. The period during which the entered level value is applied. When the level validity period expires, a warning is generated 5 minutes after the level validity period expires, an alarm is generated
6	Time remaining	Remaining time for the applied water level setting. Countdown
7	Calculated safety depth	Calculated safety depth value

Danger

Changing the safety depth and safety contour values does not account for changes in vessel height when monitoring bridges and overhead clearances.

Automatic Safety Depth Calculation

Important

To automatically account for the excess of the actual (or expected) water level above the datum to which chart depths are reduced, MANUAL ENTRY OF SAFETY CONTOUR AND SAFETY DEPTH VALUES CAN BE DISABLED.

The danger depth value \(Z_{dgr}\) is calculated automatically based on the maximum static draft of the vessel \(H_{st}\), the standard under-keel clearance margin \(dH\) to account for dynamic draft, and the excess of the current (or expected during route planning) water level above the chart datum \(d_Z\).

\[Z_{dgr} = H_{st} + dH - d_Z\]

The value of \(d_Z\) is positive if the current water level is above the chart datum, and negative if the current water level is below the chart datum.

The safety contour is selected from among the contours encoded in the ENC, with the value closest to but greater than the danger depth value.

For displaying the safety contour, the corresponding contour encoded in the chart displayed on the screen is used. For generating warnings and alarms, data from the largest-scale ENC at the vessel’s position (or during route safety check) is always used, regardless of the scale of the displayed chart.

No.	Element	Description
1	UKC Management	Select the method for entering the safety depth and safety contour. Select Enabled for automatic calculation of the safety contour and safety depth. ECDIS calculates the safety depth automatically based on the current draft setting, minimum under-keel clearance, and current water level. Simultaneously with the safety depth, the vessel’s current height above the ENC datum is recalculated. ECDIS highlights on the ENC as dangerous the contour equal to the calculated safety depth value, or the nearest deeper contour. Monitoring is performed along the selected contour
2	Water level elevation above chart datum	Manual entry of the current water level value
3	Duration	Duration of validity of the entered water level value — the period during which the entered level value is applied. When the level validity period expires, a warning is generated 5 minutes after the level validity period expires, an alarm is generated and the calculated safety depth value is reset to zero, and water level fluctuation accounting ceases
4	Time remaining	Remaining time for the applied water level setting. Countdown
5	Calculated safety depth	Calculated safety depth value

Hint

When forming a barge-tow composition, the danger depth and composition height are calculated based on the greatest draft and height values.

Chart Objects

Menu path
→ → Chart Objects

The general principle to follow when selecting chart display settings is minimizing information noise while simultaneously displaying all significant cartographic information on the screen needed for current navigational tasks.

No.	Element	Description
1	Display Mode	Display load (drop-down list) — select one of the Chart display load presets. By default, ECDIS contains three load presets: Base, Standard, and Full. These presets cannot be modified or deleted. ECDIS provides the ability to create User presets for chart display load based on existing presets
2	Save as…	Save as… saves the current display settings as a user preset. Creates multiple user presets providing optimal load for current conditions. Quick switching of chart display load is performed in **Quick Settings**

Navigational Settings

Menu path
→ → Navigational Settings

Main Parameters

No.	Element	Description
1	Chart Orientation	Chart orientation sets the chart orientation. An arrow indicating North direction is displayed in the upper left corner of the chart window. ECDIS provides four chart orientation modes: North Up (By N) — the chart is oriented with the north frame towards the top of the screen — the conventional north Course Stabilized (CRS STAB) — chart orientation relative to the stabilized heading line or a set direction (Course Up). The chart is displayed relative to the set direction — the chart is oriented by the vessel’s heading (along the vertical axis of the screen). Subsequent heading changes will cause the heading line to deviate from the screen vertical, while the image remains stationary. The heading line may deviate when “yawing”. The heading line can be corrected by pressing the button again — the image will be reoriented to the new heading. In the absence of heading data, ECDIS switches to COG orientation. ECDIS settings provide automatic correction based on the deviation criterion from the current heading in the range of plus/minus 45 degrees with 1 degree accuracy Head Up (By Course) — chart orientation based on the instantaneous heading value (Head Up). The initial direction is the monitor vertical, along which the vessel’s heading line is oriented (Heading - HDG). The chart is oriented by the vessel’s heading. The image is oriented relative to the heading line. When the heading changes, the image rotates relative to the stationary heading line. In the absence of a heading sensor or heading sensor data, ECDIS will orient the chart relative to COG By Route — the chart is oriented along the direction of the current route leg. The mode is only available when a route is activated
2	Motion Mode	Motion mode — select absolute or relative motion mode. The motion mode selection is independent of the chart orientation mode. Both modes are available at all scales with any chart orientation Relative Motion Mode — the chart shifts in the direction opposite to the vessel’s velocity vector, the vessel symbol is stationary. Navigational settings provide the ability to change the position of the displayed chart area and the own vessel’s position on the ECDIS screen True Motion Mode — the chart is stationary, the vessel symbol moves. Navigational settings provide the ability to enable vessel mark reset. When the vessel mark reaches the set value (from 10% to 75%) of the screen edge position, the mark is automatically shifted by a specified distance from the opposite screen edge in the direction opposite to the vessel’s current heading
3	Set Fix	Set offset the cursor will change to . Using the left mouse button (or screen touch), set the vessel mark position in the chart window. The vessel symbol will be placed at the specified position. The offset is applied not to the chart but to the window. Fixed offset only works in Relative Motion (RM) mode. When switching to True Motion (TM) mode, the offset is reset automatically
4	Reset Fix	Disable offset the fixed offset will be disabled. The vessel position will be moved to the centre of the screen
5	Display Reset in TM	Vessel mark reset in TM mode sets the boundary value at which the chart will be refreshed, as a percentage of the chart panel size
6	Display Reset in HDG STAB	Reset in stabilized heading mode sets the permissible heading deviation value above which the ENC will be reoriented

Note

Navigational settings allow configuring the chart display mode in accordance with current navigational tasks. It is recommended to use True Motion when navigating in confined waters and Relative Motion when navigating in the open sea.

Important

Course Up and Head Up orientation can be performed based on manually entered heading, or on COG calculated during dead reckoning with drift correction.

SSE Messages

SSE (System Security Error) — error codes defined by the IHO S-63 standard. Errors and warnings that occur when working with charts, licenses, and certificates are recorded in the Installation Logbook. Some errors, such as SSE-25 and SSE-27, are also displayed in the permanent indication area.
