Overall operation related changes
Following alarms have been made available for recording into the Voyage log:
· 2007, 2008, 2009, 2010, 2013, 2478, 2480, 2488, 2489, 2492, 2493, 2494, 2495, 2496, 2497 2498, 2498, 2501,
2503, 2504, 2505, 2506, 2507, 2509, 4027, 4028, 4029, 4030, 4031, 4033, 4034, 4036, 4037 and 4055
Following alarms have been removed from recording into the Voyage log:
· 2471 and 3201
Changed behaviour for following alarms
· Alarm "2010 Filter: Pos source change" : Kalman Filter and two GPS. Before change alarm 2010 was activated
also if only one DGPS lost differential signal. After change alarm 2010 is activated for above case only if
positions of two GPS separates more than 30 meters. The new behaviour remove unnecessary alarms for short
periods of lost DGPS, if there are no other consequences than lost differential mode.
· Alarm "2013 SOG COG unreliable"
· This has been too aggressive in rough sea condition (for ex. 40-50 separate alarms per 4 hours
period). After change the alarm condition lasts for 10 minutes, if second alarm occurs within 10
minutes. This will change separate alarms as one long alarm condition.
· This has been problematic for fast vessels and fast manual manoeuvres. Logic has been changed:
Alarm is not generated, if autopilot is not used or it is used in Heading Control mode. Vessels with
fast manoeuvres ("Max rate of turn" limit > 150 deg/min) use increased detection level for COG/SOG
unreliable condition.
AIS and ARPA targets viewing limitations
· Before change common limit for AIS and ARPA targets displayed on top of chart was 1:1 000 001 both for
ARCS and S57 charts. This was a problem for Ocean areas with ARCS charts, because large enough ARCS
charts were not available. After the change ARCS has display limit set so that AIS and ARPA targets are
displayed on top of the largest scale Ocean charts (original scale 1 : 3 500 000) when they are zoomed to
overscale.
AIS target data display
· Repeated messages received from shore station, following rules apply:
· If direct message from a target is not received then repeated message can be accepted.
· If direct message from a target is received then repeated message is not accepted.
Activation of Kalman Filter
· New behaviour includes a reset to position before activation of the Kalman Filter. This removes possibility that
own ship position jumps a lot after activation of Kalman Filter.
Changed Wind indication
· Before change the system indicated "True Wind" value based on the standard IEC 61162-1. After change the
system indicates "True Wind" as commonly understood by mariners. In practise old mode indication NORTH
and TRUE are replaced by indications TRUE and RELATIVE.

Following formats for Route Backup & Restore are available:
· Old formats: a) INC, b) ANTS, c) ASCII PROPRIETARY (previously name was ASCII)
· New formats: d) ASCII POSITION, e) ASCII WPNAME POSITION, f) ASCII POSITION WPNAME, g)
ASCII FULL. The idea behind the new formats is to enable exchange of route data between ECDIS and
common Office software for PC.
Chart related changes
ARCS charts
· ARCS Skipper service level is now available.
S57 charts
· Telecomm service from a RENC has removed (Primar-Stavanger will close this service from 6 of May 2004).
Conning Display related changes
Changed terminology in Track Pilot window:
· Previously used term "AUTOPILOT" is changed to "RADIUS Ctrl" or "HEADING Ctrl" depending on
selection on Track Pilot.
· Previously used term "ROUTE" is changed to "Goto WP" or "Goto Track" depending on selection on Track
Pilot.
Steering related changes
Double gyro interface for "DNV NAUT-AW" has been added. Also software of EMRI trackpilot has been changed.
The benefit of these changes is that loss of active gyro does not cause stop of track control as before.
· Gyro 1 is connected directly to ECDIS.
· Gyro 2 is connected through Trackpilot
Added use of last plausible speed, if all speed sources are lost in middle of track control (Goto WP, Goto Track or
Program Track steering mode). This is indicated with red text (LAST):
· In SOG field on upper right corner of ECDIS screen
· In Speed window of Conning Display
Following alarm has been added:
· “2510 Disabled: Out of turn”
Sensor related changes
Closed contact based interface for Central Alarm Systems has been added. This interface operates through Badapter. It is possible a) to acknowledge any alarm or B) mute the buzzer without acknowledge
Display alternatives
Display aspect ratio (Width : Height)
· Now displays with aspect ratio (4:3) or (5:4) can be used. Previously only displays with aspect ratio (5:4) could
be used. This change was done because many new flat screen models are based on (4:3) aspect ratio.

· "Ass. Turn enabled" when WP approach acknowledged
· "Assisted turn" during the turn
· With "Goto Track" following terms are in use
· "Goto Track" between Waypoints
· "Track Appr. enabled" when WP prewarning acknowledged (prewarning available if
prewarning alarm enabled in Installation Parameters)
· "Track Turn enabled" when WP approach acknowledged
· "Track turn" during the turn
· Indication in red text (corr) is available for following planned courses, if these values are gyro error
compensated:

· Next
Position sensor related alarms
· Scattered SOG and/or COG from sensors causes a new alarm "2013 SOG&COG unreliable"
· If alarm 2013 is active, the system does not use dynamic WP for turns in "Goto WP" steering mode
· Alarm "2007 Position Discrepancy" is activated if set limit is exceeded between "Primary" and any
"Secondary" position sources or set limit is exceeded between own ship position and any position sensor. If
Kalman filter is in "ON" position the sensor who caused alarm 2007 is excluded from position calculation of
Kalman filter.
Position sensor related indications
· Together with alarm "2007 Position Discrepancy" a textual indication "Discrepancy" is shown for position
sensor in Pos page of Sensor.
· If position sensor has been excluded from position calculation by Kalman filter, a textual indication "Excluded"
is shown for position sensor in Pos page of Sensor.
Track Pilot related alarms
· Lost heading causes a new alarm "4055 Gyro Error (Trackpilot)"
New indication window for pending state and progress of Harmonization of Multi workstations operation mode
· Permanently shown with smaller window when harmonization is in pending state or in progress
· Details of harmonization in progress can be viewed or hidden on display
Route Monitoring
· It is now impossible to select a Planned Route as Monitored Route, if it contains geometry check errors (for
example waypoints are too close to each other etc.)
· Waypoint names are displayed together with waypoint number (before only number)
· List of waypoints is also available as narrow window on information area
· changed terminology for WP information
· Next WP changed to To WP
· Time changed to ETA
Route Planning
· Optional Voyage Optimization System (VOS) has not been available since 01.01.2000.
Alarms in general
· If an alarm is based on a state - for example missing sensor signal - then a silent pending alarm stay after
acknowledge of the alarm until the state changes.
· New relay output from B-Adapter for IEC 62065 Track Control standard related alarms. This relay open if any
of related alarms is unacknowledged for 30 seconds.
Operation mode of ECDIS
· A new mode for ECDIS has been added, which is called "Standby". Standby mode is intended for staying in a
harbour, when you need to switch off audible alarms from the ECDIS.

Steering related changes
Activation of Track steering ("Goto WP" or "Goto Track"). New preconditions to activate:
· Own ship position should be inside planned channel limit when "Goto WP" or "Goto Track" is activated.
Otherwise alarm "2477 Disabled: Out of channel" is generated and steering mode is not changed to "Goto WP"
or "Goto Track".
· If the Filter does not have high precision position sensor for calculation and position discrepancy limit between
primary and secondary sensors is exceeded, an alarm "2499 Disabled: Needs good Pos." is generated.
· If speed used by Kalman filter calculation is below limit set for track steering in Installation Parameters, an
alarm "2502 Disabled: Need higher Spd" is generated.
· If there is no direct sog/cog sensor available, an alarm "2508 Disabled: Need sog/cog ref" is generated is user
try to activate "Goto Track".
Condition required for Track steering ("Goto WP" , "Goto Track" or "Program Track"). New conditions:
· If the Filter does not have high precision position sensor for calculation and position discrepancy limit between
primary and secondary sensors is exceeded, an alarm "2478 Route: Needs good Posit." is generated.
· If speed used by Kalman filter calculation is below limit set for track steering in Installation Parameters, an
alarm "2501 Route: Needs higher Speed" is generated when steering mode is Goto WP or Goto Track.
· If speed used by Kalman filter calculation is below limit set for track steering in Installation Parameters, an
alarm "2502 ProgTrack: Need higher Spd" is generated when steering mode is Program Track
Separate forwarding distance tables for "Goto WP" and "Goto Track" (earlier one common table in use):
· Forwarding distance table for "Goto WP". This table is used also with "Radius Control" or "Program heading
change" steering modes
· Forwarding distance table for "Goto Track". This table is used also with "Program Track" steering mode
· Also Forwarding distances are protected against accidental changes by Key Disk
New Program Track steering mode replaces old Program Track Turn steering mode. The difference is that new
Program Track is a continuous mode while old Program Track Turn was valid only for a single turn. The new
mode has better performance because the continuous mode allows the system to learn effect of wind, current etc.
Behaviour of the steering related features fulfil new IEC 62065 Track Control System rules. Below is some
examples of changed behaviour
· After a fatal position or speed sensor problem the system continue Goto Wp, Goto Track or Program Track max
10 minutes (before there was no time limitation for continuation). Following alarms cause this condition: 2493
ProgTrack: Needs Filter ON", "2494 ProgTrack: Needs Log sens.", "2495 ProgTrack: Needs diff Pos." and
"2503 ProgTrack:Need higher Spd" , "2475 Route: Needs filter on", "2476 Route: Needs log sensor",
"2478 Route: Needs good Pos", "2501 Route: Needs higher Speed", "2507 Route: Need sog/cog ref.", and
"2509 PrgTrack:Need sog/cog ref". Discontinuation is known as Track Control Stop. If Goto Track or Goto
WP steering mode is in use Track Control Stop is indicated with alarm "2497 Route: Stop - Sensor Fail". If
Program Track steering mode is in use Track Control Stop is indicated with alarm "2496 ProgTrack:Stop-
Sensor Fail".
· If high precision position sensor is lost (alarm "2492 Route: Needs diff Pos" ) or if there is no disrect sog/cog
sensor available (alarm "2507 Route: Need sog/cog ref." ), when Goto Track steering mode is in use, system
continues max. 10 minutes and then changes automatically to Goto WP steering mode with alarm 2489.
· New style of alarms and indications associated for waypoint approach and passing
Position discrepancy relation to track steering
· Operation of Kalman filter is now dependent of active position discrepancy alarm (alarm "2007 Position
discrepancy"), A small position discrepancy alarm limit gives extra protection against unpredictable rudder
movement.

Improved documentation
· A new chapter has been added about expected performance under various environmental conditions
· A new chapter has been added about expected performance under critical failures
Chart related changes
ARCS charts
· A history log has been added to record load and update of charts
S57 charts
· SENC conversion speed has been improved in general. Also the SENC converter can perform multiple updates
in one sequence without writing the intermediate results into Harddisk. This further speed up SENC conversion
for large amount of updates.

Overall operation related changes
Radar echo overlay
· Radar echo trails on ECDIS has been changed from green to blue colour.
Navigation tools (Tool Set 1 and Tool Set 2):
· In Tool Set 1 presentation of VRM, EBL and Parallel Index are as dashed line type.
· In Tool Set 2 presentation of VRM, EBL and Parallel Index are as dotted dashed line type.
The system has been made compatible with draft INS standard. (In future the INS standard will be used for all
equipment which do things outside their traditional scope of features). The modifications include:
· Following alarms has now pending condition (i.e. silent version) after they have been acknowledged and if the
reason of the alarm still exist: 1200, 2004, 2005, 2007, 2008, 2055, 2056, 2057, 2058, 2455, 2457, 2460, 2461,
2462, 2469, 2475, 2476, 2480, 2493, 2494, 2495, 3500, 3501, 3502, 4001, 4002, 4005, 4006, 4007, 4008, 4009,
4010, 4011, 4012, 4013, 4014, 4015, 4016, 4017, 4018, 4019, 4021, 4022, 4023, 4024, 4025, 4026, 4027, 4028,

4047, 4048 and 4049.
· Alarms 4027, 4028, 4029, 4030, 4031, 4032 has new text "4027 DGPS lost" etc. (before "4027 DGPS pos.
source change")
Navigation sensors:
· Distance and Trip counters have separate fields both trough water and over ground distances.
Presentation of Time and Date in ECDIS:
· In ECDIS local time is indicated with text "LOCAL TIME" (before it was used specific name for local time
zone).
Steering related changes
New steering mode "Program Track" which replaced old steering mode "Program Track Turn"
· This modification added a new continuous Track Control mode in which the user specify manually on-line turns
and legs
Adaptation of new IEC 62065 standard for Track Control
· This modification make the operation of the system compatible with the requirement of IEC 62065. The
modifications include:
· "2485 Route: WP prewarning" is now acknowledgeable visual indication instead of alarm (i.e. it is now silent)
· "2451 Route: WP approach" is now either acknowledgeable visual indication or alarm (before an alarm)
· The system do continue GotoTrack, GotoWP or ProgramTrack max 10 minutes, if the Kalman filter is not in
use or if the Kalman filter do not have enough sensors included. Before the system continued these steering
modes indefinite, but repeated an alarm every 15 seconds.

Overall operation related changes
Terminology used in ECDIS is harmonised to comply with IMO resolution MSC 64 for Integrated Bridge System
(IBS).
· Terms Speed Made Good (SMG) and Course Made Good (CMG) have been changed to terms Speed Over
Ground (SOG) and Course Over Ground (COG).
· Term Course, where it was used to mean the horizontal direction in which the longitudinal axis of a ship actually
points or heads at any instant, has been changed to Heading (Hdg):
· Alarm "2002 No course available" has been changed to "2002 No heading available"
· In Spd/Crs page of Sensor Manual Course has been changed to Manual Heading.
AIS Targets
· It is now possible to display AIS targets top of ECDIS chart presentation.
· New alarms include :
· alarm "3500 AIS target overflow" if Maximum count of AIS targets set to be displayed on
ECDIS has been exceeded within defined Maximum range.
· alarm "3501 AIS target storage full" if Maximum count of AIS targets which can be
stored for displaying on ECDIS has been exceeded.
· alarm "3502 Dangerous AIS target" if AIS target has met dangerous target limit set by
CPA and TCA.
· alarm "3503 Lost AIS target" if no update information received from AIS target within
defined reporting interval of vessel type.
· alarm "4037 AIS receive error" if connection to AIS transponder fails.
Common reference system
· It is now possible to configure multiple ECDIS workstation to use common harmonised data bases (i.e. Charts,
User Charts, Routes, Pilot Data etc.), common Alarm management, common Sensors and common Navigation

Chart related changes
S57 and ARCS charts
· Method to display availability information such as "larger scale available" has been chart harmonised between
S57 and ARCS
· The system maintain internal availability catalog and stores it into the harddisk. This has speed up operations
such as "Initial delay during start up", "Date dependent" dialog, use of "Catalog" etc.
· Default used Presentation library for ECDIS has been changed from version 3.1 to 3.2 as IHO has published a
new one.
S57 charts
· All attributes, which were previously only available as coded text strings, are now displayed in plain text.
Before on "Tidal panel data" had this feature.
· A new selection to display cancelled charts in RENC using S57 Catalogue.
ARCS charts
· ARCS catalogue uses now common backdrop chart with S57. It is always automatically available. Use of low
resolution ARCS charts in this system is discontinued after this improvement.
· ARCS charts can be used with new Skipper licence for non-SOLAS purposes. SOLAS users continue to use
Navigator licence as before. The main difference of Skipper and Navigator licence schema is that Skipper
licence do not include updating and thus the charts are not maintained up-to-date as required for SOLAS
purposes.
· In ARCS Catalogue available up-to-date situation of chart with different colours based on ARCS weekly Update
CD-ROM information which is loaded into ECDIS last time.
· If ENC chart is available from the area of ARCS chart it is now indicated.

Overall operation related changes
Navigation sensors
· If position alignment is used then user is reminded of it every 30 minutes. Alarm "2011 ChartAlign: over 30
min".
· In multiple sensor case the Kalman filter indicates changes in its position sources with a new alarm "2010 Filter:
Pos source change".
· Kalman filter uses always higher priority for known high precision position sensors than for normal position
sensors (i.e. A DGPS has always higher influence to estimate than a GPS or LORAN)
· Alarm "4027 DGPS pos source change" uses now always a continuous beep until acknowledged. Before the
beep style was dependent of the steering mode. Also the priority of this alarm is readjusted (before some less
important alarm could suppress it in the priority list).
· Alarm "2008 Filter. Speed below 4kt" is now based on ground speed (before water speed). The Kalman filter
indicates this situation also with an permanent indication of BAD FILTER.
· Reference target based gyro error correction has now an alarm for lost correction value. Alarm "2353 RefTgt:
Lost gyro corr.".
· Activation of Reference target requires that there is at least 8 free tracking channels available. If the connected
ARPA radar has less than 8 free tracking channels then there is an alarm "2353 RefTgt: Tracking full".
Route Monitoring
· Selection of "Center and border lines for ARPA radar display" in route monitoring window is dependent of used
radar display type.
· Alarm "2457 Route: Outside channel limit" is activated once when the ship goes out of the channel limits.
Before the alarm was reactivated every 5 minute. NOTE the permanent indication of "OUTSIDE CHANNEL"
operates as before and give always an indication of route tracking status.
Past Tracks
Own ship has now three separate past tracks:
· "System", which is the past track of the system position used for navigation and steering.
· "Primary", which is the past track of a position sensor selected as Primary.
· "Secondary", which is the past track of position sensors selected as Secondary.
Speed Vectors
· There is now a selection between true and relative speed vectors for own ship and ARPA targets. Before only
true vectors were available.

System Configuration
ECDIS EC1000 Workstation displays electronic seachart and operates as user interface for the System.
ECDIS processor is connected to various sensors, does navigation calculations and route monitoring. Connections to
interfaces are typically made with serial communication lines.
ECDIS processor can be used for both route planning and route monitoring. If required, there can be additional
identical ECDIS EC1000 Workstation(s) connected to the same Local Area Network to share tasks of ECDIS. If
more than one ECDIS EC1000 Workstations are connected into the System, one or more Workstation(s) can be used
as user interface (with full usage rights) and one or more workstation(s) are used as planning station (Usage rights as
Planning).
If the System has two or more Workstations connected together as Multi workstation, the system keeps data on
Workstations harmonised and also tracks selections and settings made on any Workstation.
Typically there can be following kind of configurations of Workstations:
· Mode as Single, only one Workstation is used in the System.
· Mode as Multi, two or more Workstations are used in the System where Usage rights and
Sensor source of Workstations can be changed by the user.

Route Planning
Modification an existing route or creating the whole new route is the way to do Route planning.
Definition of route consists following:
· Position of each waypoint · Safe water calculation based on Safety limits
· Turning instruction for each waypoint · Required steering accuracy for individual leg
· Safety limits between waypoints (channel limits) · Speed restrictions for a leg
Information notebook:
· Information pages to alert operator at a given waypoint or in the selected area.
· Automatic and/or manual notebook function to tell operator position based information.
Voyage optimisation parameters.
Route Calculation
Route calculation for voyage planning includes following:
Route profile calculation:
· Distance between consecutive waypoints · Total distance
· Course between waypoints · Estimated time for voyage
· Calculation of wheel over point ·
Route check
· Grounding alarm based on available depth information in digital chart data base
22 · Navigation Tasks
Page 39
Voyage optimisation:
· Time table optimisation
· Optimisation based on economical factors
· The ECDIS processor calculates optimum speed and course between each waypoint, ETA and fuel consumption,
based on the defined data. There are 4 calculation strategies: Max. Speed, Timetable, Lowest Cost and Best
Profit. In case of great circle sailing between two waypoints the ECDIS calculates max. and min latitudes and if
needed adds an extra waypoint not to go over min or max. latitude.
Chart planning
1. Loading of new S57 and ARCS charts
2. Updating on existing S57 and ARCS charts
3. Handling of chart permits
4. Manual update
User Chart planning
1. User generated navigation charts
2. User defined chart alarms based on symbols, lines and areas of User chart

ECDIS Screen
Overview
Parts of the ECDIS display.
The ECDIS (Electronic Chart Display and Information Systems) screen includes several areas. There is statusbar at
the top and the bottom of the screen, which are shown permanently. The upper and lower right hand corner is taken
up by permanently shown information in Information area. Between these areas there is a Dialog box area where
user can fill or choose appropriate options. The left hand part of the ECDIS screen is the Electronic chart area.
When the push button is pressed from the Control Panel appropriate menu opens up top of chart legend.
ECDIS Screen · 27
Page 44
Electronic chart area
The ECDIS can use the following types of charts:
· S57ed3 ENC charts (vector)
· CM-93 charts (vector)
· ARCS charts (raster)
There can also be displayed following information:
· cursor moved by trackball
· planned route
· EBL (Electronic Bearing Line) and VRM
· symbol of ownship with speed vector
· targets acquired by ARPA
Electronic charts in ECDIS
The electronic navigational charts are displayed in Electronic chart area. There are two kinds of electronic
navigational charts available to use in the ECDIS:
· S57ed3 ENC or CM-93 vector format
· ARCS raster format
S57ed3 ENC and ARCS electronic charts may substitute official paper charts. User should check the current
situation from his flag country administration and if in doubt use the paper charts as primary source of navigational
information.
ECDIS combines chart and navigational information. It should be noted that modern navigation systems (e.g.,
differential GPS) may offer a more accurate positioning than was available to position some of the surveys from
which the electronic navigational chart was derived.
S57 vector format:
ECDIS is compatible with S57 release 3 ENC format. From this format the ECDIS generates the “System ENC”, =
SENC, which is used for actually for operations the ECDIS.
When opening a chart it is displayed with default scale called compilation scale. It is possible to modify details of
chart displayed in Electronic chart area. You can change scale of chart by pressing ZOOM IN and ZOOM OUT
pushbuttons. Scale range is 1:1 000 - 1:50 000 000.
CM-93:
Compatibility with CM-93 format depends on commercial agreements. Some versions of this ECDIS are compatible
and others are not. The compatibility is controlled by the security device called dongle. From CM-93 format the
ECDIS generates SENC which is used for actual operations of the ECDIS. The difference between S57ed3 ENC
charts and CM-93 charts is that the CM-93 charts are from a private source and they cannot be used as a substitute of
paper chart under any condition. To highlight that part they are later called as NON-HO charts in this manual.

S57 vector chart presentation
ARCS raster format:
ARCS charts are digital reproductions of British Admiralty (BA) paper charts. They retain the same standards of
accuracy, reliability and clarity as paper charts.
Zooming into the ARCS chart can be useful for magnifying complex detail, but decreases the density of data
displayed, and can give a false impression of distance from danger. Therefore it is possible to zoom 2*original paper
chart's scale or ½*original paper chart's scale.

Conditions required to replace
paper charts
Introduction
Carriage requirement for adequate and up to date charts for intended voyage can be found from SOLAS Chapter
V/20 of the 1974. In resolution A.817(19) IMO has specified how requirement of the V/20 of the 1974 can be
fulfilled with a device called ECDIS. In resolution A.817(19), Appendix 7 (RCDS 1998) IMO has specified how
requirement of the V/20 of the 1974 can be fulfilled when an ECDIS uses RCDS mode. The traditional alternative
way to fulfil requirements of the SOLAS chapter V/20 of the 1974 has been the use of paper charts.
If you use type approved version of this ECDIS (BSH type approval certificate number 6579 / 080 138 / 99. If in
doubt, contact your supplier of the ECDIS to check the status of your system) and if following conditions are met,
then your system fulfils IMO A.817(19).
· own ship area is covered with updated ENC charts
· your selected display area is covered with updated ENC charts
· you have a backup system which fulfils IMO A.817 requirements. One example is a second
ECDIS
Note that ENC producers provide their conditions of use in the Publisher notes, which you should read always when
loading new material into the ECDIS. See chapter "How to load S57 charts from a CD-ROM, floppy or LAN" on
page 73.
In areas where ENCs are not available raster chart material called ARCS from UK HO can be used in the ARCS
mode of this ECDIS, if following additional conditions are met:
· own ship area is covered with updated ARCS charts
· your selected display area is covered with updated ARCS charts
· appropriate folio of up-to-date paper chart is carried onboard and available, if required by your
flag country administration

How to detect ENC coverage in S57 Chart display
This Electronic Chart System has capability to show more than one S57 Chart cell at the same time. This feature is
called multi cell display. If one S57 Chart cell does not cover the whole display the system will open more S57
Chart cells to be displayed, if they are available in displayed area. The Upper Status bar shows information about
S57 Chart cells displayed on the Electronic chart display area. When automatic TM reset is active, the information
is displayed from position of own ship. When automatic TM Reset is OFF, then the information is displayed from
current position of cursor.
The list of possible indications:
RCDS mode: Raster chart material is displayed on electronic chart display area.
Non ENC Data: The S57 Chart at cursor location is not official ENC material.
No indication: The S57 Chart at cursor location is official ENC material
Areas which are covered by legal ENC data are indicated with ENC coverage symbol (This symbology is used by
IHO S-52 Ed. 3.2. or earlier Presentation Library). See following examples.

Vector Chart material
Introduction
Theoretically a chart can be coded for computer as raster or vector chart. There is a special chapter for raster coded
charts in this manual. Vector coded charts can be coded using different techniques. One technique is called S57ed3
and this technique has been selected by IMO as the only alternative for SOLAS compliant electronic charts. If a
S57ed3 coded chart is published by government authorised Hydrographic Office, then it is called ENC. If a S57ed3
coded chart is published by private industry, then it is called as NON ENC. Another technique is known as CM93/2. It is used by private company C-MAP to publish electronic charts. All CM-93/2 charts are NON ENC. There
is a special chapter about C-MAP charts in this manual. You can read more about ENC and related legal issues in
chapter "Conditions required to replace paper charts". Later in this manual all references to Vector Chart material
are under name S57 Charts regardless of the source of them.
Sometimes you may wish to add manually Notices to mariners or Navtex warnings into your S57 charts. In this
system this kind of things are called as Manual Updates. Manual updates are valid for both S57 and ARCS charts so
that you need to define them only once. Also manual updates are valid for all scales so that you don't need to repeat
them for charts published in different scales from the same area. See more details in chapter "Manual Updates" .
S57 Charts
Introduction
This Electronic Chart System is compatible with official IHO S57 release 3 chart material produced by
Hydrographic offices (HO). This material, when issued by government authorised Hydrographic Office, is called
ENC (electronic navigational chart). Use, presentation and display of S57 charts are based on International
Maritime Organisation (IMO), International Hydrographic Organisation (IHO) and International Electrotechnical
Commission (IEC) regulations and rules (S52ed3.1). When this ECS (Electronic Charts System) uses ENC (S57
release 3 chart produced by a government authorised Hydrographic Office), it is an ECDIS as defined by IMO, IHO
and IEC.
An ENC could be encrypted to prevent unauthorised use and then the user needs a permit to view the ENC. This
permit could be entered manually from control panel or loaded from a floppy disk.
Before any ENC can be used in the ECDIS, it is loaded into the hard disk and converted into the system’s own
internal format (SENC). Some parts of the charts may be date dependent i.e. they are visible after a set date or they
are visible only for a limited period etc. In this Electronic Charts System you control all date dependent objects with
Display Until and Approve Until dates. In paper chart world the Preliminary and Temporary Notices to Mariners
represent the date dependency described above for S57 charts.
An important part of ENCs are the updates. Hydrographic Offices can issue two kinds of updates:
· incremental updates, which are small additions to original base cells
· reissues and new editions, which are complete replacements of previous base cells and their
updates
All updates are date stamped and they may also contain date dependent parts. You control also usage of updates in
this Electronic Charts System from Display Until and Approve Until dates. Using Display Until and Approve Until
dates you can view your charts correctly drawn on any date in the past or in the future.
Vector Chart material · 67
Page 84
Chart material will be available stored in media such as CD-ROMs and floppies or electronically from LAN (Local
Area Network) in which it could have arrived from RENCs, CD-ROMs or floppies. Such material can contain only
basic cells, cells and updates or only updates. This Electronic Chart System contains as standard delivery the
software to access CD-ROMs, floppies and LAN.
Each S57 chart may contain beside the chart itself links to additional textual descriptions or pictures. Typically
additional textual descriptions and pictures contain important sailing directions, tidal tables and other traditional
paper chart features, which do not have any other method to be included into the S57 chart. This ECDIS copies
these textual descriptions and pictures into its hard disk and allow you as user to cursor pick them for viewing
purposes.
An appendix of this manual provides short introduction for interpretation of S57 ENC chart display.
Definitions of terms
Cell
S57 chart
ENC
SENC
RENC
A cell is a geographical area containing ENC data. Each cell has separate unique name.
Hydrographic Offices divide their responsibility area into the cells which they publish.
A database, standartized as to content, structure and format, issued for use with ECDIS without
any authority of government authorized Hydrographic Office. The difference of S57 chart and
ENC is that non-ENC charts require complete up-to-date paper charts to be used as primary aid
of navigation.
A database, standartized as to content, structure and format, issued for use with ECDIS on the
authority of government authorized Hydrographic Offices. The ENC contains all the chart
information necessary for safe navigation and may contain supplementary information in
addition to that contained in the paper chart (e.g. sailing directions) which may be considered
necessary for safe navigation. The name of coding standard for ENC is S57ed3.
A database resulting from the transformation of the ENC by ECDIS for appropriate use,
updates to the ENC by appropriate means, and other data added by the mariner. It is this
database that is actually accessed by ECDIS for the display generation and other navigational
functions, and is the equivalent to an up-to-date paper chart. The SENC may also contain
information from other sources.
A service provider offering ENC delivery and update service as defined in IHO standard
S52e3. Often a RENC provides CD-ROM based service to ECDIS users. One example of a
RENC is the RENC in Stavanger operating under marketing name PRIMAR-Stavanger.

Permanent warnings of S57 charts
Permanent warning help you to keep the S57 charts up-to-date. Only up-to-date S57 charts can be legal replacement
of the paper charts. Permanent warnings indicate, if the system detects a condition which may cause your system to
use not up-to-date charts.
NOTE! The system can powerfully assist you to keep your charts up-to-date for the charts which you have got from
a RENC. For charts which has been loaded from other sources than a RENC, the system is unable to know the exact
up-to-date situation.
See more details in chapter "Date dependent and
periodical features of Vector chart".
You have loaded updates into the hard disk, but these
updates are not included into the SENC. This kind of
charts are drawn in orange colour in the Chart Plan Catalogue.
Perform SENC conversion for these charts. See
more details in chapter "How to use SENC convert
window to initiate SENC conversion".
See more details in chapter "How to know up-to-date
status of the RENC Product List".
You have loaded an update which contained cancel
information for a chart. You selected not to remove
the canceled chart. This permanent indication
reminds you about your intended use of a canceled
chart.

How to load S57 charts from a CD-ROM, floppy or LAN
When you load S57 charts by CD Catalogue, the system first load a CD catalog, which stores certain information
into the hard disk such as cells ID, their position, edition number, from your LAN (Local Area Network) connection,
floppy or CD-ROM. After that the system asks which charts will be loaded from the selected media.
After building the CD catalogue you can view the contents of it using S57 catalogue command.
Note: All CD-ROMs, floppies or LAN (Local Area Network) connections from one single National Hydrographic
Office have equal names although their contents could be totally different. You can use your own unique names to
identify them separately and correctly later.
To load by CD catalogue proceed as follows:
1. Press CHART PLAN push button.
2. Select Load from the menu and by CD Catalogue from the sub menu. A
Load CD Catalogue dialog box appears. The default load source is CDROM. Press Load and continue from step 5, if you use CD-ROM. If you
want to load from a floppy disk or from another ECDIS using LAN, you
have to change Load Dir. Press Browse to select a new Load Dir
CHART PLAN push button
3. If you use a floppy disk, select A:\ in Drive:. If you use another ECDIS using LAN, select suitable Drive: and
Sub Dir. Note that a correct load source has "\ENC_ROOT" in the end of the Current Directory: (see
example below).
Press Select when you are ready.

group and list of charts have common charts, they are highlighted in the list box.
NOTE 2! If your system has LAN (Local Area Network) and you want load your charts from another drive than
your system CD-ROM drive, press Source Dir button. Then you can define drive and path from where you load
your charts.
NOTE 3! The System can make conversion into the SENC and set the "Display Until" date automatically. This is
the recommended way. More information to set them, see chapter "How to select automatic SENC conversion and
Display Until date" on page 80.
NOTE 4! You should read the text file associated into each catalog. The text file typically contains very important
notices for the usage of the charts from the producing Hydrographic Office .
1. Press View CD Publisher Notes button in the S57 Load dialog box.

The example above contain only base cells and reissues of the charts. Charts GB204000 and GB50401S are called
as reissues, because they already include updates (GB204000 include updates 1 and 2. Gb50401S include update 1).
Charts GB304010, GB40401S and GB40501L are called as base cells, because they do not contain any updates i.e.
their update number is 0.
The example above contain both base cells and all updates of the charts from issue of base cell up to the last update.
The example above contain only updates. In example above update 3 is available for chart GB204000, update 1 is
available for chart GB40401S, updates 1 and 2 are available for chart GB40501L and update 2 is available for chart
GB50401S.

NOTE! You can not replace chart data, which is already in use unless you only replace the latest base cell or update.
If you want to reload older data again, you must first remove the chart from your hard disk (See chapter "How to
remove S57 chart cells from the system").
Messages, which require careful attention
All messages in this chapter change the legal status of the charts in your system. Study these message extremely
careful because you may need to use paper charts to fulfil SOLAS requirements

The message above clearly indicate that this chart is not up-to-date and thus it does not fulfil SOLAS
requirements. Get immediately from the publisher of this chart the new edition of the chart.
You do not have all the published updates
If you tried to load updates and you
miss one or more updates between
updates already loaded into your hard
disk and updates that you are
loading, then you get following
message:
The message above indicates that you tried to load updates number 3, 4 and 5 when at least update 2 and possibly
update 1 were not available in your hard disk. Check the content of your CD-ROMs to find the missing
update/updates or contact your chart supplier.
The message above clearly indicate that this chart is not up-to-date and thus it does not fulfil SOLAS
requirements. Get immediately from the publisher of this chart the missing updates of the chart.
Unsafe Chart has been cancelled by the publisher
If you load an update, which contain
cancellation of the chart instruction
by the publisher of it, you get
following message:
Normally you should accept the cancellation and you should press Yes. Then the system automatically removes the
chart from the hard disk and from your chart screen.
78 · Vector Chart material
Page 95
You may insist to keep the chart although the publisher of it has told you that the content of the chart is so unsafe
that they have cancelled it. The reason might be that you do not have anything better available. In this case you
press No. Then the system automatically remove the ENC status from the chart, because the publisher has told so in
his special cancellation update.
Note that the cancellation message above clearly indicate that the publisher says that this chart is unsafe for
navigation and thus it does not fulfil SOLAS requirements. Get immediately from the publisher of this chart the
new chart/charts, which replace the unsafe cancelled chart.
How to load S57 charts, which are not fully compliant with the
standards
The ECDIS could in some cases load S57 charts, which does not have full compliance with S57 standard coding for
transfer media. Minimum requirement for loading manually is legally coded:
· XXXXXXXX.000 file, which includes a base cell
· XXXXXXXX.NNN file, in which NNN is a number from 001 to 999, and which includes an
update
To load charts without building a named "CD Catalog" proceed as follows:
1. Press CHART PLAN push button, select Load from the menu and Manual
from submenu.
2. You can select desired drive and charts.
CHART PLAN push button
When ready to load charts, press Load Chart button.

S57 SENC Conversion details
S57 charts from Hydrographic offices are called ENCs. An ENC has to be converted into SENC format before it can
be used in the ECDIS. The ECDIS can convert ENC into SENC format automatically. If the conversion is
successful, the Failed SENC conversion window does not appear.
If the system fails to convert ENC into SENC or if the system detects an coding error in an ENC, a Failed SENC
conversion window appears with a list of failed ENCs. In this window you can select any of the charts to see reason
for failure in conversion.
Normally the conversion is initiated automatically from loading of the charts. Chapter "How to load S57 charts" on
page 71 describes the loading process. Chapter "How to select automatic SENC conversion and Display Until date"
on page 80 describes how you can select automatic conversion. You can also initiate conversion from a SENC
convert window or from a Cell Status window.
How to make SENC conversion faster
The SENC conversion speed depends about how many other tasks the system has. The system can do SENC
conversion as background process during any other possible operational use of the system, but you can greatly
improve the speed of the SENC conversion, if you do following things:
1. Disable Radar echo overlay. Select Radar overlay mode as ECDIS ONLY. Select control of visible navigation
features as OFF for Radaroverlay (the Radaroverlay visibility control is located in "Tracking" sheet of "Chart
details").
2. Select Display Mode as TRUE MOTION
3. Press Set Chart Center push button and allow the system to operate either in TM RESET OFF or SHIP OFF
SCREEN state
4. Press Zoom In until you reach scale of 1:1 000
How to select automatic SENC conversion and Display Until date
When you are loading new S57 charts base cells and/or their updates into hard disk, it is possible make automatic
conversion to SENC format. It is also possible to set display dates as issue dates automatically. Proceed as follows
to set these options:
1. Press CHART PLAN button, select SENC Convert Settings from the menu.
2. A S57 Settings dialog box appears:
Select Automatic SENC Conversion and Automatic Display Until options.

How to use Failed SENC conversion window
If the system is unable to convert ENC into SENC without any error or failure, a Failed SENC conversion window
appears with a list of failed ENCs. Status of Failure means that the system completely failed to convert the ENC into
the SENC and thus the ENC cannot be used.
Status of Errors means that the system detected minor or major errors in the conversion of the ENC into the SENC.
Check carefully the content of Conv history and Cell status to see, if the error was minor or major. Major errors are
indicated as NON ENC in Conv History. Note that the status of Errors together with NON ENC in Conv
History clearly indicate that this chart is not up-to-date and thus it does not fulfil SOLAS requirements. Get
immediately from the publisher of the chart the new edition of this chart.
Status of Failed means that the system completely failed to convert the ENC into the SENC and thus the ENC
cannot be used. Note that the status of Failure clearly indicate that this chart is not up-to-date and thus it does
not fulfil SOLAS requirements. Get immediately from the publisher of the chart the new edition of this chart.
The Failed SENC conversion window contains two buttons. One to open conversion history log Conv. History
and another to open Cell Status window of selected item in the list of Failed SENC conversions window.
If you use Conv. History button, a
Conversion Log appears. Conversion Log
shows the status of converted ENCs. More
information about the results of conversions,
see chapter "How to use SENC Conversion
history log" on page 83.
If you use Cell Status button, a Cell Status window appears.
Then you can push Conv Log button to open view detailed description of errors and failures detected during SENC
conversion (see example on next page.
In the example above the reason of the SENC conversion failure is a miss match of checksum (calculated crc number
differs from the expected).
