1 Introduction 

 

The purpose of this guide is to provide equipment-specific information to assist users in 

managing their AVCS ENC holdings. 

 

This guide should be used in conjunction with the AVCS User Guide, as well as the 

ECDIS Operators MManual or other documentation as supplied by the equipment 

manufacturer. 

 

The actual instructions and screenshots in this guide are based on the version of the 

MARIS ECDIS installed in the UKHO as detailed on the front cover. There may be 

minor differences between certain models and these will be highlighted in this guide 

where known (i.e. screen layouts may vary).

2 Data Management 

The “Chart handling” utility is accessed by clicking on the 

the Maris 900 ECDIS. 

-”Chart handling” icon within 

Note: All chart licensing and data management operations are carried out using the “Chart 

handling” function. 

All of the actions described in this guide should be carried out with the “ENC” and “GB” 

Tabs selected as shown below. 

5


3 The User Permit 

The User Permit is a 28 character alphanumeric string that is unique to each ECDIS 

installation or group of ECDIS, e.g. multiple bridge installations. The User Permit should be 

supplied at the time of delivery and must be used when ordering an AVCS licence and 

ENC permits. 

If the User Permit is mislaid it can be retrieved from within the system. 

Chart handling: → Get User Permit → Save in file 

1. In Chart handling select “Get User Permit" 

2. The User Permit is displayed in the “ENC User Permit” message box 

3. If required this can be saved as a simple text file. 

6


4 Deleting ENC Data 

New AVCS customers who have subscribed to other ENC services are strongly 

recommended to remove (purge) all ENC Permits and ENCs from the system before 

installing AVCS. For more information please refer to the pre-installation checks within the 

generic AVCS manual. 

Note: Do not remove the charts with the AA prefix (stored within Chart 1 tab) as they are 

IHO produced ENCs and are used as references by the Maris 900 ECDIS system. If these 

cells are removed a Maris Engineer will be required to re-install these charts. 

To remove all charts: 

Chart handling: → Select appropriate charts → Delete selected charts 

1. Select charts to be deleted (N.B. Hold Shift to select multiple charts) 

2. Select “Delete selected charts” 

3. Select “Yes” 

7


5 Deleting ENC Permits 

The user must select the charts that permits are to be deleted for. In most instances this 

will simply involve selecting all charts. In certain circumstances it may be required to 

remove permits for individual charts, in this case simply select the charts for which permits 

need to be deleted. 

In the example below permits would be deleted for the four selected cells. 

Chart handling: → Select appropriate charts → Delete selected permits 

1. Select appropriate charts from which permits are to be deleted. (N.B. Hold Shift button 

whilst selecting the first and the last Cells allows all Cells to be selected at once). 

2. Select “Delete selected permits” 

8


6 The Public Key 

The Admiralty Vector Chart Service currently uses the PRIMAR.CRT, issued by Primar 

Stavanger, to authenticate its AVCS ENCs. 

Before installing AVCS ENCs, the user must check that the correct Public Key is installed 

on the system this can be viewed in the Maris 900 using the “SA certificate” button. 

If the PRIMAR Public Key is not present on the system then it will have to be installed 

before AVCS ENCs can be loaded. 

The Primar public key is included on all AVCS Base CDs. To load the Primar Public Key 

you must first load an AVCS Base CD into the ECDIS. 

BV 

Chart handling: → SA certificate → Install SA certificate 

1. Select “SA certificate” from the chart handling menu 

2. The currently installed public key will be displayed at the top of the screen. In this case 

the “primar.crt” is installed. 

3. Select “Install SA certificate”

7 Installing ENC Permits 

The “Add permit by file” button is used to install ENC permits into the ECDIS. When 

selected a browser window will be displayed. In this window the user will have to identify 

the source folder or external drive where the ENC permits are stored. When the folder has 

been selected the user must highlight and then click “OK” to install the AVCS ENC permits. 

Cha Chart handling: → Add permit by file → Browse to permit location → OK 

1. Select “Add Permit File” 

2. Browse to Permit Location 

3. “The results of installation” will then be displayed which can be reviewed as required. 

11


8 Installing AVCS Base CDs 

There are currently 9 AVCS Base CDs but It is unlikely that users will need to install all 9 

CDs in order to load their licensed ENCs. Reference to the Schedule A to identify which 

discs are required will avoid unnecessary loading of some CDs and reduce load time. 

This process will automatically select data to be loaded according to the permit file 

installed by the user and for the majority of situations this process should be used however 

it may occasionally be necessary to load a single cell, if this is the case follow the 

Installing Selected Charts process below. 

Note: Ensure the latest permit has been installed before attempting to 

install any data 

Chart handling: → Install → Install whole charts collection → Next → Finish 

1. Insert latest Base CD 

2. Open the ENC Installation Wizard by selecting “Install” from the Chart handler Menu 

3. Select “Install whole charts collection from CD” 

4. Select “Next” 

12


5. The ENC Installation wizard will then install all cells that the vessel holds a valid Permit 

for. The Installation results can be reviewed as appropriate. For an explanation of any 

errors or warnings please refer to the AVCS User Guide. (For SSE26 error see Note 

below) 

Note: At this stage a warning will be displayed. This is the SSE26 warning described in 

section 4.3 and can be ignored. This is because AVCS ENCs are authenticated against 

the previous Scheme Administrator (SA) certificate issued by PRIMAR. 

6. Select “Finish” 

13


Note: Make sure that ALL required AVCS Base CDs have been inserted and the import 

operations completed before installing the latest Update CD. Updates cannot be applied 

unless the ENC base file is present in the system database. 

Installing selected charts (use with care) 

In the majority of cases when installing new data from CD the user will use the option 

described above. However if there is a requirement to manually select cells to install the 

process below can be used. 

Chart handling: → Install → Install selected charts and folders → Browse to 

appropriate folder(s) → Add selected folder to the list → Next → Finish 

1. Insert an AVCS Base CD into the CD Drive 

2. Open the ENC Installation Wizard by selecting “Install” from the Chart Handler Menu 

3. Select the “Install selected Charts and Folders” Option 


14


5. Browse to the CD Drive (if not automatically detected). The user must manually select 

the cell that they require to install. The data is organised by country codes within the 

ENC_ROOT folder. Select the folder for the cell requiring installation as shown below. 

6. The “Chart Details” window will display information about the cell and any associated 

updates. 

7. Click “Add selected folder to list” which will populate the charts selections window. 

Numerous folders can be added to the “Charts selection”. Select “Next” 

8. Finally click “Next” to begin chart installation. 

15


9. The ENC Installation wizard will then install all selected Charts and updates available 

on the AVCS base disk. The Installation results can be reviewed as appropriate. For an 

explanation of any errors or warnings please refer to the AVCS User Guide. (For 

SSE26 error see Note below) 




10. Select Finish”. 

16


9 Installing AVCS Update CD 

1. Insert the Weekly AVCS Update CD into the CD Drive 

Note Base CDs are re-issued about every 6 to 8 weeks. The AVCS update disc will 

indicate which Base disc week must have been installed. It is important that users do not 

attempt to load an Update CD that is not consistent with the Base CDs. 

Chart handling: → Update → Update whole charts collection → Next → Finish 

2. Select “Update” from the Chart Handling Menu 

17


3. Select “Update Whole Charts collection from Update CD” 


5. The ENC Installation Wizard will then install all charts that the vessel holds a valid 

Permit for. The installation can be reviewed as appropriate. For an explanation of any 

errors or warnings please refer to the AVCS User Guide. (For SSE26 error see Note 

below) 




6. Select “Finish” 

18


Note: Please note that it is also possible to apply updates for selected charts by following 

a similar procedure to the previous “Installing selected charts” section. However it is not 

envisaged that this will need to be used as the process described above will ensure all 

cells are updated. If it is required to apply selected updates select Update – Apply selected 

updates – then follow the “Installing selected charts” instructions on chart selection. 

19


10 Systems Checks 

The system provides the user with the capability to view the status of the system database 

against any outstanding ENC new editions and/or updates available in AVCS. This can be 

done remotely while vessels are at sea assuming it has access to the internet or prior to 

updating with the latest available AVCS Update CD. 

The Chart handling menu gives a simple indication of Chart status and Permit status for 

each cell using a simple red and green symbol. For the three scenarios shown below it can 

be seen. 

1. A valid permit is held but the chart is not installed. 

2. Chart has been installed but there is not a valid permit. 

3. The Chart is installed and a valid permit is held. 

To resolve scenario 1 install chart from latest AVCS Base CD and Update using latest 

Update CD. 

To resolve scenario 2 install Permit for charts that have been installed. 

For scenario 3 no action needed as both Chart and Permit are installed.

Emergency Chart Permit Generation 

In certain circumstances it may be necessary for a vessel to get access to an AVCS chart 

at very short notice, for instance if a vessel needs to be diverted due to a medical or 

safety emergency. In these emergency circumstances only, individual AVCS ENC 

Permits can be obtained from the UKHO 24 hours a day, 365 days a year. These permits 

can be transmitted direct to the vessel by email wherever possible, by fax, or simply by 

reading the characters out over the telephone or radio. 

To obtain an AVCS emergency permit please contact UKHO Customer Services during UK 

normal office hours using the contact details at the end of this guide. Outside of office 

hours please contact the UKHO Watchkeeper by emailing navwarnings@btconnect.com, 

phoning +44 (0) 1823 353448 or faxing +44 (0) 1823 322352. Please quote your Vessel 

name, the User Permit 1 Number of your ECDIS system and the required ENCs.
