Volume 1 – Description and Operation Part 2 – ADP System

Enable button – the [ENABLE] button must always be pressed in conjunction with
any other button to activate a request on this panel. Alarm silence and Lamp test
are the exception and do not require the enable button to be operated.

Control Transfer - the [Control Here] button is used to transfer control to/from this
panel. The button LED flashes when control is available and changes to a steady
light when the button is pressed, indicating control is at this panel. See Chapter 2
for vessel specific changeover scheme.

Manual X, Y Joystick Control - the joystick provides manual control of the vessel
in the fore/aft (X-axis) and port/stbd (Y-axis) directions and is available in JSMH
and JSAH. The joystick also provides fore/aft control for pilot modes and sailing
modes. The level of thrust is determined by the amount the joystick is moved in the
X and Y axes. The toggle [Joystick Power] button provides a choice between
reduced power for full deflection of the joystick. The selected power setting is
indicated by LEDs above the button.

Manual Heading Control - the heading control knob provides manual rotation of
the vessel around its centre of rotation (COR). The action of the knob depends on
the control mode selected. In JSMH mode the amount of turning movement about
its centre, to port or starboard, is proportional to the amount the knob is rotated.

Change Position in Auto modes – The incremental buttons provide the facility for
making incremental adjustments of the vessel position in the fore/aft (X-axis) and
port/stbd (Y-axis) directions and are available in Auto Position modes (e.g. DP,
Minimum Power, ROV etc.). The toggle [Position Change Increment] button
provides the choice between 1m and 5 m increments. The selected increment
setting is indicated by LEDs above the button. The [Change Position] buttons are
used to move the vessel in fore/aft/port/stbd direction. Pressing the centre [Fix
Present Position] button stops any incremental movement and selects the current
vessel position. The operator will also have these facilities available from the
workstation display (if fitted)

Change Heading in Auto modes – The incremental buttons provide the facility for
making incremental adjustments of the vessel heading in auto heading modes. The
toggle [Heading Increment] button provides the choice between 1 and 5 degree
increments. The selected increment is indicated by LEDs above the button. The
[Change Heading] buttons are used to select the direction of rotation. Pressing the
centre [Fix Present Heading] button stops any incremental movement and selects
the current vessel heading.

In all modes, except JSMH and Min Power, the heading control knob can be used
to setup a heading change, up to 170 degrees port or starboard, around its centre.
The heading change is implemented by pressing the [Set Heading]. The speed of
rotation is set by the operator using the [Change Heading] button on the Motion
Display page.

Control Mode Selection - Control mode selection buttons are provided for JSMH,
JSAH, DP, Min Power and Auto Pilot. These buttons are configurable for the
vessel. See Chapter 3 for configuration of button labels for this vessel.

Dimmers and Lamp Test - The rotary [Dim Graphics] knob adjusts the brightness
of the lights under the button descriptions.

The rotary [Dim Lamps] button adjusts the brightness of the button LED indicators
and the LCD Display backlight.

The [Lamp Test] button illuminates all button LEDs and drives the LCD display with
a test line.

Alarm Acknowledge - the [Comms Alarm] button LED indicates a communications

failure between the ADP operator controls and processor. Pressing this button
accepts the alarm and silences the buzzer. The button LED lights again when
communications are restored.

The [System Alarm] button LED flashes when any system alarm is activated.
Pressing the button accepts the alarm and the LED changes to a steady light. The
LED extinguishes when no alarm is present.

Heading and Position LCD Display - the left hand side of LCD Display shows the
actual measured vessel heading (H) and the set heading (S). The right hand side
of the LCD Display shows either joystick demand (0-10)/turning moment demand
(±10) or radial error/linear distance to destination depending on the control mode
selected.

Volume 1 – Description and Operation Part 2 – ADP System

Brightness Control rotary knob varies the brightness of the display to
compensate for different ambient lighting conditions.

Light Sensor – the display has two modes of operation: ‘auto’ and ‘manual’. When
‘auto’ is selected, by a button on the rear maintenance panel, the brightness setting
is controlled by the Light Sensor on the front panel. However, the Brightness
Control overrides the Light Sensor to some extent to allow for user preference.
When ‘manual’ is selected, the Brightness Control operates normally and the Light
Sensor is de-selected.

Auto Indicator - LED lights (green) if light sensing is in ‘auto’ mode. The
brightness of the LED varies with ambient lighting.

Power Indicator - LED lights (green) when the main display screen is switched on
by the On/Off rocker switch at the rear of the monitor. Warning: mains voltages
may be present within the unit whether the Power Indicator is lit or not.

Power Switch (at rear of display) - The On/Off rocker switch controls power to the
display. Display ON is designated by the ‘I’ side of the switch being depressed and
the green rocker edge showing. Display OFF is designated by the ‘0’ side of the
switch being depressed and the black rocker edge showing. Warning: Parts of the
internal circuitry will remain at mains potential even when the switch is OFF.

On Screen Display (OSD) Panel (at rear of display) - the two-position Control
Panel Enable toggle switch should only be used by technicians to set-up the
display. It activates the on screen display (OSD) control panel and lights the green
LED when switched on. Normally the OSD control panel should be switched off
(LED off) to prevent accidental adjustment of stored settings.

Velocity TAB Velocity sets the velocity at which the target

moves toward the destination. The velocity
can be set by selecting the button and
entering a numeric value or by moving the
slider. The target is accelerated up to the set
velocity and decelerated as it approaches
the destination. Note that if the distance is
short, the vessel may not reach the set
velocity.
Acceleration/Deceleration Multiplier used
to adjust the set acceleration and
deceleration values by applying a multiplier
between 0.1 and 2.0. A value of 1.0 leaves
the set value unchanged. The default values
for the multipliers (which are used unless the
operator intervenes) are 1.0 for acceleration
and 0.5 for deceleration. Thus, if a more
rapid slowdown is required, e.g. in the event
of high cable tension, the value of the
deceleration multiplier should be increased.
Emergency Deceleration Multiplier the
multiplier is used when the operator requests
fast controlled stop.
Fast Stop stops the vessel at the higher
deceleration rate.
Stop stops the vessel using the normal
acceleration/deceleration multiplier.
Continue continues the movement.

TAMS TAB Control Circle Radius the operator can set

a limit, if the vessel exceeds this limit the
control system will re-act.
Target Lock the operator can lock the target
to be an unchangable control point. i.e. the

4.9 SYSTEM STATUS SUMMARY

The number of circles depends on whether the system has one, two or three
controllers. The examples are for a triplex system.

Information Type Description

Normal healthy state with all controllers

operational without faults.

A flashing red mismatch indicates that

one of the controllers (or possibly two)
have a selection of sensors, PMEs and
thrusters which do not match those of the
Online system.
The normal procedure would be to bring
up the System Status display (see 5.5.1),
check the reason for the mismatch and, if
appropriate use the “System Copy”
button to re-align the controllers.

The flashing red mismatch has the same

significance as above, and requires the
same action.
The addition of a flashing yellow circle
indicates that because of the reduced
selection of either sensors, PMEs or
thrusters, that controller would not be
able to support the current control mode
if it were to be the Online controller.

The red cross indicates that the third

controller is not operational and the
system has degraded from triplex to
duplex.

The two red crosses indicate that the

second and third controllers are not
operational and the system has further
degraded from duplex to simplex.

User Notes: For all sailing modes, surge (Y-axis) control

is unavailable. However, the operator can still make
changes to surge control to prepare for sailing mode
deselection. A sailing mode with Auto selected for surge
causes the vessel’s speed to be determined from the
Track Setup page rather than the joystick.

5.4 CONTROL SETUP

The Control Setup page(s) contains tabs which are used to enable the operator to
set up the various vessel parameters.

5.4.1 COR (Centre of Rotation)

The COR page enables the vessel control point to be determined. The control point
is the position about which the vessel rotates, and acts as an offset when all
measurements are referenced to the centre of the vessel.

The Display list allows the control

points of the vessel to be shown on
the mimic diagram by clicking the
appropriate [COR-] boxes. The
currently selected COR used by the
control system is shown as a red
circle.

The Selection list allows one of the

preset COR 0-3 or operator defined
COR 4-9 control points to be
selected. The currently selected
COR is shown by the option button.
Changing the COR is performed by
clicking the appropriate option
button and then confirming using
the Confirmation window.

Fast Learn control system builds up a model of the average environmental force
that the thrusters are counteracting over a period of 12 minutes. The current value
of this force can be displayed on the Motion Page as the Sea Force vector. If the
vessel is subject to a large change in the environmental force acting upon it (which
might occur if a large heading change is made) then the current value of
environment force will be incorrect until it is gradually corrected over a period of 12
minutes. The Fast Learn facility is used to reduce the time it takes for the system to
re-estimate the change in force.

The following options are available:

Fast Learn selects fast learn.

Permit Manual Selection allows the
operator to select fast learn.
Permit Plant (Automatic) Selection
allows fast learn when triggered by the
plant. e.g if a fire monitor pump is
started then this will cause a force on
the vessel, fast learn can be
automatically selected when the fire
pump is started. This will minimise the
excursion.

The Coordinate Setup page can be used to:

• View the PME device used as reference in the last calibration, shown as Available and in
Use.

• View or change the designation of a device used as a PME Reference.

• View, write in, or calculate the base position of a local PME device.

• Compute the coordinate origin.

• For Artemis only, toggle the base station in use between 1 and 2.

The operator can select which available PME

devices can be used to compute the co-ordinate
origin.

Re-compute a calibration occurs and all the

other PME devices will have correction vectors

with the vessel position from the reference PME
device.

The calculation is allowed if the reference PME

device is selected for use by the control system
and a gyrocompass is selected. If not, calibration
is not permitted and a reason is displayed below

5.9 POSITION MEASUREMENT EQUIPMENT

The PME pages contain tabs which are used to display the various configuration
pages:

5.9.1 Summary

The Summary page displays Position

Measurements and Position Errors from each
selected PME device.

PME Channel Colour codes:

Grey background – pme unavailable
White background – pme available but not selected
Green background – pme available and selected

Position Measurements of the vessel is defined

as:

DGPS - absolute easting and northing coordinates

of the vessel’s centre point, as measured by the
DGPS.

Acoustic - seabed distance of the acoustic

transponders from the vessel’s centre point
measured in fore/aft coordinates converted to
northings and eastings, or the absolute position of
the vessel centre measured by the acoustic
system.

Position Errors are defined as the distances

between the target positions and the control points.
All errors are measured in vessel coordinates
(metres).

Nine PME channels are available (A-I), with the

current allocation shown by the PME Channel
selection buttons.

User Note: display order, aerial offsets, frequency settings,

mobile or fixed are setup using the PME Maintenance Setup page.

Align Errors – checks the performance of a

suspect PME device. Clicking this button makes
each selected PME device error simultaneously
equal to the average PME value at that instant. On
the Motion Page this has the effect of briefly
superimposing all PME error symbols on top of
each other before spreading out again under the
influence of their respective measured data.
User Note: Consideration should be given to deselecting a
doubtful device.

5.9.2 Repeatability

The Repeatability page gives an indication of how

good or bad the position data is for a particular
PME device in bar-chart form. As a general rule,
the smaller the bar the better the position fix quality
is for the device. The size of the bar is based on
the standard deviation of the position fixes over a 5
minute period. The blue bar is the Present Value
of data quality and the white bar is the Previous
Value of data quality. The data is updated every
60 fixes received.

This page can be used as a quick guide to:

• PME performance prior to selecting for use with

the ADP system (in the case of good
performance).
• PME performance prior to deselecting (in the
case of poor performance).

5.9.3 Medians

The Medians page enables the PME signals to be

checked against a preset Rejection Limit. If three
or more PME devices are selected then it is
possible to use only those, which are within the
rejection limit. The median check finds the median
value of three or more PME devices in the X-axis
(surge) and Y-axis (sway) and calculates the
average position value for use by the control
system. Any devices which falls outside the
rejection limit are discarded and not used in the
calculation of the average position value. Only one
healthy device can be discarded in any one check.
So, if two or more devices fall outside the rejection
limit at once, not all will be rejected.

Rejection Limit the operator can set the limit down

to a minimum of 2m. The rejection limit is then
displayed as a square box on the centre of the
page.

The operator has the option to display any or all of

the PME devices. PME are selected by clicking on
the required icon.

The Scaling 5m slider enables the scale of the

page to be set to display the rejection limit box and
PME comfortably.

5.9.4 Weightings

The PME Weightings page can be used to set a

bias towards preferred PME devices.
Each PME is given a weighting value from 1 to 10,
where 1 is the lightest and 10 the heaviest. The
weighting can be selected either manually or
automatically by means of the toggle

Manual weightings are entered by clicking on the

data entry box adjacent to the PME device and
entering a value from 1 to 10 via the numeric
keypad. Manual weightings are selected at bottom
of page.

Auto weightings is based on the Repeatability for

each PME.The Weight percentage (%) is
calculated for each selected PME device, based on
the weighting value compared to the sum of the
weighting values for selected PME.

Scale/Value option buttons at the bottom of the

Window Value column can be toggled to show
either a scale factor or the size of the rejection
window for each PME device. The rejection
window size can be set individually for each PME
by clicking the appropriate Window button and
entering a scale factor in the range 1 to 10 via the
numeric keypad. The rejection window provides
the first level of checks applied to the position fixes
received from the PME systems. The current
position fix is compared to the model predicted
position fix and is accepted if the difference is less
than that specified in the rejection window.

The size of the rejection window is a product of the

Kalman Gain distance and the scale factor. The
Kalman Gain distance in metres corresponds to
the Gain set in the Control Gains window.

Example of Kalman Gain selections and range of

Rejection window sizes:

Kalman Gain 0 – Scale 1 –10 represents 8 –80m

Kalman Gain 1 – Scale 1 –10 represents 16 –160m
Kalman Gain 2 – Scale 1 –10 represents 32 –320m
Kalman Gain 3 – Scale 1 –10 represents 64 –640m
Kalman Gain 4 – Scale 1 –10 represents 128 –1280m
Kalman Gain 5 – Scale 1 –10 represents 256 –2560m

User Note: the operator should become familiar

with the range of rejection window sizes.

6. ADDITIONAL PAGES
Additional pages can be configured for specific vessel operations, these page(s) will
be accessible from the Mimic index or may be configured in the display footer.

6.1 VESSEL OPERATIONS

6.1.1 Analysis

The Analysis page provides the facility to predict

whether the thrust demands currently calculated by
the control system will be satisfied in the event that
one of a number of predefined failures occur. The
consequence of analysis are shown as a
continuous updated display together with alarms
which are activated when the failure of a single
alarm would result in an unsatisfied demand.

The basis of the analysis

calculation is to take the
present thrust demands (as
required for the current
environmental conditions)
and the present thruster
selections and examine the
effect of a single failure in
those conditions.

The Analysis page displays the consequence of

the following:
Analysis by Thruster shows the consequence
analysis based on failure of individual thrusters.
The system sequentially fails each selected
thruster in turn to check if the demand can be met
without it or if the remaining thruster configuration
is insufficient to meet the requirements of the
current control mode. Vessels equipped with
rudder(s) are treated as thrusters and failure is
tested in the same way as for each thruster. Only
selected thrusters/rudders are considered in the
analysis and those not selected, even if available,
are not included.
Analysis by Bus Section shows the consequence
analysis based on failure of all thrusters on each
bus zone. The consequence analysis considers
the failure of each section, with the bus-ties open,
by simulating a failure of all thrusters connected to
that section and assessing the ability to satisfy the
current thrust demand with the remaining selected
thrusters. The bus section is designated as
“essential” if the demanded thrust cannot be met
without it or if the remaining thruster configuration
is insufficient to meet the requirements of the
currently selected control mode.

6.1.3 Capability

The Capability page provides an offline facility to

check the ability of the vessel to maintain position
and heading under different environmental
conditions, with different combinations of thrusters,
generators etc. The Capability page is divided into
several areas, some used for setup and calculation
and some for displaying results.

The capability plot is carried out in two stages:

Setup and Perform Calculations

User Scenario the

operator can configure
which thrusters,
generators and bus-ties
are selected for the
calculation. The hotel
load and thruster mode
can also be configured.

To perform the calculation(s), the required

conditions are setup by the operator and the
Perform Calculation button clicked.

Power Scenario Selections:

Full all equipment is selected as available.
Present the current vessel configuration is
selected.
User - The configuration is set by the operator
using the button in the configuration area on the top
right of the page.
User-Thruster calculations are made with each
thruster failed in turn, to determine the worst result
for each angle.
User- Generator calculations are made with each
generator failed in turn, to determine the worst
result for each angle.
User- Bus calculations are made with each bus
section failed in turn, to determine the worst result
for each angle.

User Note: For Full, Present and User configurations the system
o
calculates the critical windspeed at 15 angles using the set
conditions. The display plot has the same colour as the selected
button. For User -Thruster, User -Generator and User -Bus, the
o
system calculates the critical windspeed at 15 angles with one
device failed at a time. The worse case is then selected. The
minus plots may contain different failed devices at different
angles.

Correction offsets in the Fore/Aft and

Port/Starboard directions. Velocity measurements
are calibrated (i.e. corrected) to:
Remove any systematic error in the measurement.
Remove the effect of a non-zero sea current for
water locked measurements. A calibrated water
locked measurement should reflect the vessel
movement across the earth, not relative to the sea
current Each device has its own calibration. Also,
water lock and bottom lock measurements are
separately calibrated.

A velocity estimate is available from each PME

device’s measurements. For all fixed PME devices
in the Kalman pool, these velocities are grouped
together to form a PME estimated velocity average.
Calibration of the velocity measurements is
achieved by comparing the PME estimated velocity
average with measurements from each of the
devices.

Although velocity devices provide measurements in

X-Y axes, the system calculates calibration
corrections in N-E axes. The reason for this is that
compensation for sea current (for water lock
measurements) is best performed in these axes.
The filter used in calibration requires several
minutes to identify the corrections. Velocity devices
are not deemed to be calibrated for several
minutes, although the devices can still be used by
the control system.

Calibration of the velocity devices is NOT a one off

‘initialisation’ calculation. Calibration occurs
continually whenever fixed PME devices are in the
Kalman pool. Calibration is suspended when fixed
PME devices are not available, but any previously
identified calibration correction remains and is
applied to the raw velocity measurements. If
calibration has not occurred for 30 minutes (chosen
in a fairly arbitrary manner), the devices are
deemed to have inaccurate calibration.

6.5 CONSEQUENCE ANALYSIS

6.5.1 Analysis

The TAMS Consequence analysis forms part of the

overall system, performing calculations on the
failures of anchors, thrusters and bus sections. For
each failure the system will predict if a tension,
position or heading alarm limit will be activated.
Any predicted consequence alarms will be passed
to the control workstations and alarmed to the
operator. The operator can then use the APS to
analyse the alarms in more details to decide on a
course of action. The system will check each
anchor, thruster and bus section in turn and will
take approximately 10-15 seconds for each item,
typically 10 anchors, 3 thrusters and 4 bus sections
will take approximately 3 minutes.

Failure Condition each anchor, thruster and bus

section will be individually tested against current
environmental conditions.
Predicted Alarms, excursions in tension, position
or heading are checked against the current alarm
levels set in the control system. OK indicates the
system is operating within the specified alarm limits
and a single failure will not cause the limits to be
exceeded. Alarm indicates a low/high tension level
has been activated by one of the other anchors.
The alarm will be passed onto the control system
informing the operator that the APS has detected
an alarm on failure and the operator needs to
analyse and take action, if necessary. n/c indicates
not checked, which will happen when a mode
change is made, vessel is re-configured etc. The
n/c should clear on the next cycle when all changes
to the system are complete.
Calc view the red marker shows which item is
currently being analysed. Clicking this area allows
the operator to analyse the failure condition
(anchor, thruster and bus section). The selected
failure condition is analysed using the associated
Deviation and Trends page.

A change has been made to the control system

setup i.e. anchor pattern, water depth etc. these
changes will invalidate the consequence analysis
routine. A pattern not validated alarm is produced

consequence analysis to operate with the new
pattern setup. To validate the new pattern the
operator will press the here button.

6.11 SIMULATION
6.11.1 Overview

The Simulation page provides an offline training

facility. To select simulation mode all thrusters must
be deselected and therefore not under A-Series
control. Inputs and outputs are processed by the
control system to simulate control of the vessel
without actually supplying power to the thrusters.

User Note: simulation will not be possible if thrusters are

available to the A-Series DP control system, this also includes A-
Series manual and joystick control.

The Overview page shows the current status of the

parameters set up for simulation.
Simulation tick box enables the simulation mode
to be selected/deselected via of the Confirmation
window.

User Note: simulation will only be available when

no thrusters are switched to A-Series control.

Simulation Clock can be set for three different

speeds to suit operator requirements Fast,
Medium or Normal.

User Note: the simulation clock function will not be available on

vessel simulators only standalone desktop simulators.

Alarm Buzzer can be disable for simulation

purposes.
Zero Velocity will immediately set the vessel
movements to zero. Which is useful if the operators
loses control of the vessel and wants to start again.
Model parameters the operator can setup the
water depth and vessel draft .
External Force the operator setup a force
magnitude and direction and position it is applied
to the vessel in a fore/aft and port/stbd position.
Environment the operator can setup the wind,
waves and current Setpoints. Drift can be used to
increment the setpoint.

7. CONTROL MODES
The different types of ADP vessel control are called control modes which are
described in this section. To operate the vessel in a particular control mode
requires specific inputs (sensors and PME) and specific thruster combinations to be
selected, if available, before the control mode is permitted to be selected.

Sensor, PME, thruster and mode selection is made from the active ADP
workstation.

The control modes provided by the control system are:

• Monitor
• Joystick Manual Heading (JSMH)
• Joystick Auto Heading (JSAH)
• Dynamic Positioning (DP)
• Mobile Follow
• Minimum Power
• Ship Follow

controlled independently or as a combination.

Joystick movement controls the thrust on the vessel in the

B fore/aft and port/starboard directions, using the selected
thrusters. The thrust can either move the vessel or hold it
stationary against the environmental conditions. The
further the joystick is pushed the greater the thrust
produced on the vessel. When the joystick is pushed fully
over, the vessel has maximum available thrust in that
direction. Power provided by the joystick can be full or ½
power as selected by the Joystick Power button.
A
The Heading Control Knob rotates the vessel about its
centre of rotation, using the selected thrusters. The more
the knob is turned the greater the moment of thrust. To

This mode maintains the vessel position relative to a

moving remotely operated vehicle (ROV), with automatic
heading control. Two types of ROV mode are available:

• Fixed distance.

• Fixed position reference.

If the selected position measuring equipment (PME) is the

ROV hydro acoustic beacon then the fixed distance mode is
used. In fixed distance mode the vessel’s COR and the
ROV ROV’s transponders/responders are maintained at a fixed
distance.

If at least one other PME device is selected, as well as the

ROV hydro acoustic beacon, then the fixed position
reference mode is used. In this mode the vessel is
maintained in a fixed position whilst the ROV is allowed to
move within a ‘reaction radius’. If the ROV moves outside
its reaction radius the vessel COR follows the ROV and the
reaction radius is repositioned. This minimises thruster
activity.

DP Vessel This mode is for vessels operating alongside moving

structures/vessels. For this mode to function the vessel
must be fitted with a laser system (e.g. CyScan). The Ship
Follow mode and laser system allows the control system to
automatically track the relative position and heading of the
target structure/vessel.

circle (radius set by the operator) to be placed around the
target vessel’s reference point. If the target vessel moves

outside this circle the DP vessel will automatically move.
Similarly, if the relative heading changes by more than a
preset limit then the DP vessel will automatically change
heading. In this mode the operator can still change the DP
vessel position and heading relative to the moving
structure.

7.20 MODEL CONTROL

Model control is a mode that is automatically entered if there is a failure of all the
vessel’s reference systems (sensors and PME). The model continually monitors
and stores data from the sensors, PME and thrusters. Model control allows the
vessel to be controlled for a period of time using the data stored at the time of
failure. Eventually the vessel will drift off course due to prevailing weather
conditions.

Model control will allow the vessel to be brought under manual control in a safe and
orderly manner.

9. CHARTS
9.1 ADMINISTRATION

The Admin Æ Chart Database menu option will

result in the presentation of the dialog illustrated
below. The Chart Database Admin tab of this
dialog enables the user to view the currently
registered chart databases together with their issue
numbers. Note that the installation process will
have already registered a ‘World’ database and an
‘ENC’ database, these will appear in the list of
registered databases with the ‘World’ database
selected as default.

The following additional actions can be taken :

• ‘Copy Database to HD’

When a new chart CD or DVD is obtained from C-
MAP, this option can be used to update the chart
database information. The user navigates to the
location of the database on the right hand ‘file
system’ view (e.g. D:\CM93_3 ). At this point the
‘Available Database’ box will show the name and
Issue number of the database (e.g. ‘World Issue
Number 200’). If this issue number is greater than
the one shown for the registered database then the
user can chose the ‘Copy Database to HD’ option
and then select a location on the hard drive to copy
the database to (e.g. ‘C:\Program Files\CM93v3
SDK\DataBases’). The copy process will then start,
this may take several minutes. Note that this step
also registers the database automatically and it will
appear in the list of registered databases.

• ‘Register Database’
As an alternative to the above process, the
system is able to register a chart database from its
current location (e.g. on CD). Access from CD will
be slower and is not recommended. It will also be
necessary to have the CD in place whenever you
wish to use this database.

• ‘Set as Default’
This option enables the user to select a database
from one of the registered databases on the left-
hand pane and register this database as the
default database for the system. The currently
selected default database will be indicated with a
green tick. tick.

• ‘Unregister Database’
This option is for advances users only. Selecting
this option will unregister the selected database,
resulting in the loss of all C-MAP licenses for the
database, which then needs to have its licenses
reapplied.

• ‘Check Signature’
This option is intended for advanced users, and
allows the user to check that the currently selected
database has not been corrupted.

The Chart Database Selections tab of the dialog

enables the user to selectively activate and
deactivate all registered chart databases. Refer to
the dialog illustration below. The pane on the left of
the dialog shows the chart databases that are
currently active and which will be used to construct
the chart. The right-pane allows the user to
deactivate or activate the currently selected
database from the Available Chart Databases list
box by clicking on the appropriate button. The
Active Chart Databases list box will be updated.

Chart License Administration

The Admin Æ Chart License menu option will

result in the presentation of the dialog illustrated
below. The License List button is initially selected
and the right pane view will show the current list of
C-MAP licenses that are active for the currently
selected C-MAP database. The Database may be
changed by selecting a different database from the
drop down list at the top of the dialog.

Note that the system identity is also shown on the

dialog (e.g. System ID : Converteam eT 00001),
this identity should be used when applying for
licenses to C-MAP. It corresponds to the e-Token
dongle identity. The e-Token dongle should always
be present in the USB port of the PC when
applying licenses.

The C-MAP licenses appear as a string showing

the expiry date (Oct 2005), the chart area for the
license (zone 0), and the license number. e.g. :
10-2005 : Zone 0 – 1D11AA6DFA67D42C.

• ‘Add Licenses from file’

This option allows the user to add a license for the
currently selected database (selected in drop-down
list) from a ‘password.usr’ file that he has obtained
from C-MAP (license@c-map.no). This file is
obtained from C-MAP after sending them the
‘User.usr’ file located in the C-MAP installation
directory, C:\Program Files\CM93v3 SDK, or
quoting the System ID string also shown on the
license dialog. On receiving the ‘password.usr’ file
from C-MAP this should be copied to a location on
the hard drive and the Add Licenses from file
button selected. The user can then navigate to the
location of the ‘password.usr’ file and select the OK
button to apply the license.

• ‘Add License Manually’

The user may also opt to add the license string
manually license for the currently selected
database (selected in drop-down list). This situation
could arise for example after having contacted C-
MAP by telephone. In the Data Set or Area Name
box select the Zone or Areas which your license
has been generated for (Zone 0 represents the
whole world).The license string quoted by C-MAP
for the system ID / Data Set combination should
be entered in the space at the bottom of the dialog
and Add License button clicked. The license string
used in the previous example of this section for
Zone 0 would be ‘1D11AA6DFA67D42C’. (not case
sensitive).

Note that each license string must be applied

separately for each Zone, Area and Cell that has
been ordered from C-MAP. However, in such cases
C-MAP will send a ‘password.usr’ file containing all
this information and the ‘Add Licenses from file’
procedure may be used.

• ‘Get Expired Licenses’

This option enables the user to check for expired
C-MAP licenses at a set date in the future. The
date in the ‘Expiry Date’ box can be altered and the
button ‘Get expired licenses’ clicked. A list of all C-
MAP licenses that will expire before this date will
be displayed. In the example below, the Zone 0
license will expire before the date, 03-2006.
Note that the system will generate an alarm every
24 hours for two months prior to the expiry of any
C-MAP chart license. During this time period, this
alarm will also be generated after a reboot. This
license check will be on a per ‘chart database’
level.

• ‘License Order’
This option is not used at present.

Chart Updates Administration

The Admin Æ Chart Updates menu option will

result in the presentation of the dialog illustrated
below. The dialog enables the C-MAP chart
databases to be brought up to date as per the
latest ‘Notices to Mariners’ issued by the
appropriate source agency and received at C-MAP.
There are several update options that are available
:
• ‘Auto Updating’

This option enables the automatic update of the

selected chart database though a direct Internet
connection with C-MAP’s servers in Norway. Select
the All button to enable download of all available
updates. The updates will be applied immediately
after downloading.

Prior to downloading, the Size button may be used

to estimate the size of the data that will be
received.

The update process will take a minute or two

depending on the speed of your Internet
connection and the number of updates to be
applied. You must of course have a valid C-MAP
license in order to receive the chart updates.

• ‘Semi-Auto Updating’
This option should be used if, for some reason, a
direct Internet connection is not available so that
the Auto-Updating method cannot be used. In this
case the updating via E-mail service may be used.
In order to apply E-mail updates :

• Select the maximum return e-mail size to suit

your e-mail system.

• Select a folder to save an order file (e.g.

c:\temp) and press the Save Order button.
This will store a ‘*.ORD’ order file in the
selected directory which will contain all the
information required for updating (including
license limitations).

• Attach the save ‘*.ORD’ file to an e-mail and

send to updates@c-map.no This service is
automated and there is not need to type any
text within the e-mail.

• An automated reply should be received in

about 5 minutes. The attached file with the
updates should be saved to a suitable area on
the hard drive, copied to CD, flash disk, floppy
disk, etc.

• Now, on the C-MAP PC locate the updates file

and select the Get Updates from button. All
updates from the file will be applied and
registered.

• ‘Updating Log Review Updates’

After updating, the list of updates can be reviewed
with this option. The list in the left part of the panel
contains all datasets (charts) to which updates
(corrections) have been applied. The information
related to each dataset includes : Updates Status
(Accepted or Declined), number of updates to the
dataset and the date.
The list on the right part of the panel contains the
updates sorted by which Hydrographic Office has
issued the update. The user may browse the tree
on the right-hand list box and can double click on
any of the updated objects in order to re-centre the
chart at the updated object position. The user may
find it more convenient to select a ‘Mercator’
projection whilst browsing chart updates which are
scattered in different areas of the world. This will
avoid having to select suitable UTM projections for
the particular updates being browsed.
