1 GeneralThis chapter provides an overview of the Icon system and a technical description of themain components that give the required knowledge about the system.The figures,drawings and text in this chapter are general and may not comply to the actualinstallation on the vessel. For details on the delivered equipment, see chapter 4 Delivery
Specification.
2 System Overview
2.1 Main ComponentsThe redundant Icon DP 2 system is based on a triple controller solution with a redundantfibre-optic network. Interface to sensors and position reference systems, power system
and thruster system are split into logical groups, based on class requirements and systemsegregation.
The connected nodes do not need special functionality to handle network redundancy.With the DP system integrity preserved, the DP network is separated from networks ofother applications. The DP cabinets, operator stations, sensors and position referencesystems are dual powered from the redundant UPS system.
A typical Icon DP 2 system configuration is illustrated in Figure 1. It shows how thesystem parts communicate with each other. See chapter 12 Design Drawingsfordelivery specific details.
A typical system may consist of the following:
Three control cabinets (triple redundant controllers), alternatively a large singlecabinet.
Redundant fibre-optic network
Two or more Icon operator stations with:
- high-resolution colour LCD with touch-screen interface
- Joystick device
- Positioning device
- Remote display controller (located in the operators chair)
Printer(s):
- for printing of alarms, trendings etc.
Manoeuvring mode selector switch
Sensors and position reference systems (of different types)
Two UPS (Uninterruptible Power Supply)
Interfaces to thruster devices (I/O modules or Rolls-Royce HeliconX3).

2.2 Thrust Allocation
Note: A thrust device can be any propeller, thruster or rudder.
The force demands in surge and sway and moment demand in yaw from the controllerhave to be distributed to each thruster as pitch and/or rpm setpoints and (if applicable)directional setpoints.
The thrust allocation in the Icon system takes into account:
Available power on each bus bar. The Icon system will not enforce thruster action thatexceeds the available power.
Optimal thruster utilisation in normal operations.
Turning rate of thrusters, pitch and rpm response. The direction of azimuthing thrusterscan either be variable (auto direction) or fixed in a set of pre-defined configurations.
Grouping of thrusters. Two or more thrusters can be arranged to be working as a group.The purpose is often to reduce changes in thruster direction. In cases where thrusterscannot produce negative thruster force (reverse direction), this ensures that the thrustdemand is fulfilled without unnecessary turning of thruster direction.
Fixed thruster direction configurations or variable thruster direction.
Forbidden sectors for thruster direction.
2.3 Signal ProcessingAll measurements to the Icon system have to pass several levels of testing and
processing before being used in the control of the vessel. The type of testing andprocessing functions used, is dependant on the signal source.
See section 4.4 Signal Processing Functions.
2.4 Vessel Model (Filtering and Estimation)Oscillatory motion caused by waves will not be compensated by the thrusters, main
propellers and rudders in auto heading and auto position control. Advanced adaptivewave-filtering and estimation techniques in combination with the internal vessel modelare used to generate estimates of the low-frequency motion of the vessel thatautomatically adjusts to the varying sea-states and operational conditions. The estimatedmotion (vessel speed, rate-of-turn, position and heading) is used in the feedback controlof the vessel.
2.5 Trajectory GeneratorDuring automatic change heading and change position operations, the internal trajectorygenerator ensures a smooth change of the vessel heading and position. The vesselmotion is according to the operator defined motion settings (maximum surge and swayspeed and rate-of-turn). The start-up and end phase of the movement are automaticallyadjusted according to the capacity of the propulsion equipment installed.

2.6 Feedback and Feedforward Control
The feedback controllercomputes the required surge and sway forces and yawingmoment to keep the vessel on the desired position, heading or track in automatic controlmodes of operation. The individual position and heading control gain settings influencehow aggressive the system will respond to deviations in position and heading.
Automatic control modes also use reference feedforward control action, based on thetrajectory generator to speed up the response of the system in change position andchange heading operations. Wind measurements are used for wind compensation. I.e.the wind force and moment acting on the vessel is derived from wind speed anddirection, wind drag coefficients and wind areas scaled by draught measurements. Thecorresponding wind feedforward counter force and moment are commanded.

3 Design
3.1 Manoeuvre Mode Selector
3.1.1 Switch
The manoeuvring mode selector switch (DP selector switch) is used for the selectionof operational mode (independent Joystick control/Manual/Icon control). The switch islocated on the bridge.
Figure 4 Example of a Manoeuvring Mode Selector Switch
The manoeuvring mode selector switch can also be used for a fast disconnection of theIcon system, in case of an emergency situation.
A fast disconnection will cause the separate thruster/rudder control systems to beenabled instead of the Icon system.
3.1.2 System
The manoeuvre mode selector system allows more than one manoeuvre mode selector
switch to be installed. The design and implementation of the MMS system is based onthe idea that each of the control systems to be used for controlling the thrusters shall beselectable independently. I.e. a failure in one system shall not prevent that anothersystem may be used as a backup.
Figure 5 Example of a MMS Operator Panel
The MMS system itself is used as a signalling device for enabling mode changes. Theactual mode switching is a result of signal communication between DP, JS and each ofthe RTCs. The communication protocol is based on the existing Ethernet communi-cation interface.
To ensure that the rudders are available whenever the propellers are available for DP/JSoperations, a digital signal from the propellers RTC is used. By combining thetraditional DP/JS request signals with this new signal, a safe enabling/disabling of therudders for DP/JS operation is obtained.

3.4 Additional Operator Station (Optional)
Depending on the class notation and class society there will always be one or morerequired main operator stations. Additional operator stations can also be delivered.These operator stations are delivered as fully or more limited equipped versions.
A fully equipped operator station will have the same hardware components as a main
operator station.A limited operator station will have a smaller display and will not be able to presentinformation to the same extent as a fully equipped operator station.
Note: Additional operator stations may not confirm with class requirements.Which operator station to use for a given operation, should be chosenbased on type of operation, area of operation and the risk involved.

3.7 Thrust Devices
Note: The Icon system is controlling the thrust devices via a correspondingremote control system.
3.7.1 Status and Settings
RuddersThe operator can set the maximum permitted rudder angle for manoeuvre operations.
In addition, it is possible to fix a rudder in neutral position (zero angle) such that therudder is not actively used.
Azimuth Thrusters
To achieve the optimal system performance, the Icon system will normally actively usethe steering of azimuth thrusters (auto direction) to obtain the best overall utilisation ofthe thrust devices. However, it is possible to fix a single azimuth thruster to a set of pre-defined, fixed directions (typically towards port, starboard, aft, forward). Similarly, agroup of azimuth thrusters will be defined to take a set of fixed directions (typically two
azimuth thrusters aft).

Pitch/Rpm Combinator
The Icon system is configured for combinator run in cases where the thrust device canactively control both rpm and pitch of the propeller. The combinator curves areoptimised for each propeller with respect to:
Fast thruster force generation
Noise and vibration
Fuel consumption.
Transfer to Lever Control
During operation, the operator can transfer a thrust device to manual lever control. Thisfunctionality depends on the type of remote control system for the specific thrust device.The command transfer to lever control is by the give-then-take principle. First, the thrustdevice is disabled from the Icon system. Secondly the operator must take command onthe lever unit and then control the thrust device manually.
From the Icon system the operator can re-enable the thrust device for Icon operation at
any time.Some examples where such functionality might be useful are:
Transfer of main propellers (and rudders) to lever control and use the remainingthrusters for heading control only
Transfer of a swing-up thruster to lever control and keep the remaining thrust devicesfor positioning and heading control by the Icon system.
3.7.2 Failure Detection and Failure Handling
Communication and Signal Monitoring
The Icon system continuously monitors and compares the thrust device feedback andorder signals by the setpoint-feedback monitoring function. Any significant steady-statedeviations will result in an alarm.
When thrust device signals are hardwired between the Icon system and the thrust device,the signals out of range (typically an effect of a broken wire) will issue an alarm.
Communication errors between the Icon system and the thrust device will automaticallybe detected.
Insufficient Thrust Configuration
The Icon monitors the system's ability to perform the requested operation based on the
present thrust configuration. The thrust configuration depends on: Number of active thrust devices
Fixed or automatic direction on azimuth thrusters and rudders
Power system configuration and loads.
When the system is no longer able to generate force in surge or sway or moment in yaw,insufficient thrust configuration alarms will be issued.
Example 1
If the system is operating with active sway control and a thruster is lost such that swayforce no longer can be generated without also introducing a large moment, the system
will not be able to keep a safe operation. An insufficient sway configuration alarmisthen issued and also clearly indicated on the graphical display.

Example 2
A vessel with two azimuth thrusters aft in a fixed direction configuration. If one of thethrusters is lost and the other remains fixed in a certain direction, the Icon system cannotnecessarily generate thrust in all three axes. An insufficient configuration alarmis thenissued and also clearly indicated on the graphical display.
Note: If azimuth thrusters or rudders are set to fixed direction and insufficientthrust configuration occurs, the system will, if necessary, automaticallydisable fixed directions and set the direction control to auto.
Note: If the operator (on purpose) would like to reduce the number of activethrust devices such that an insufficient thrust configuration situation willoccur, it is recommended to disable surge and/or sway from active control
in order to avoid the alarm situation.

3.8 Sensors and Position Reference System
Note: For detailed information about sensors that are part of the Icon delivery,see chapter 14 Subsuppliers Manuals.
Information about sensors that are notpart of the Icon delivery, seesensor system suppliers manuals.
A number of sensors provide the interfaces for various operator devices monitored bythe Icon system via the control cabinet. In addition to gyro compass, such devices can
be hydro acoustic, laser based, radar based, VRUs, wind sensors, or GNSS etc.
Class rules regulate minimum system requirement. The Icon system requires interfaceto accurate position measurement systems (typically differential GNSS referencesystem). The Icon system also will have interface to at least a wind sensor (relative windspeed and direction) and a vertical reference unit (VRU) for measurement of roll and
pitch angle of the vessel.
3.8.1 Multi Sensor System Handling
The Icon system can be connected to more than one sensor of the same type. Whenmultiple sensors are used the system will do a weighting between the signals based onthe signal quality, see section 4.4 Signal Processing Functions.
The Icon system will automatically detect unacceptable deviations between sensors ofsame type and an alarm will be issued. If an error is detected in a sensor, the weightingfunction automatically decrease the weight factor of that sensor to a minimum. Instead,the factor from the other sensors of the same type is increased. The operator can alsodisable a sensor and thereby stop it from being used.

4.2 Graphical User Interface
4.2.1 GUI Philosophy and Interaction
The Icon system operations are performed via the operator devices and the graphical
user interface (GUI). The most common operations can be performed by using dedicatedpush-buttons on the operator devices. For details, please refer to the User Manualchapter 6 Operating Instructions.
The graphical user interface is designed to be a tool for monitoring and activelycontrolling the system through intuitive presentation and touch-screen principles. Theamount of information presented on the display is restricted to the basics necessary forthe operation of the system. This helps the operator to focus on the most vitalinformation.
To achieve the best visibility of the graphical interface, the system can be set to differentcolour schemes:
Day-colour scheme with light background colour
Night-colour scheme with the darkest background colour.
A change of the colour scheme will have effect on all operator stations simultaneously.
Status Indications and Colour Codes
In the GUI, different colours are used for the visualisation of:
Selected and activestatus of thruster device, sensor or position reference system
Online standby state
Alarm status
Feedback signals
Setpoints, orders and other operator inputs
Negative measurements.

4.3 System OperationThe Icon operator stations have a high resolution colour display with a touch-screeninterface. Any operation of the system can be performed through the graphical interface.In addition, the most common operations can be performed by means of dedicated push-
buttons on the operator devices.
For details, please refer to the User Manual chapter 6 Operating Instructions.
4.3.1 Basic Operational Modes
The Icon system comprise the following basic operational modes:
Standby
Joystick
Positioning.
Standby
Standby is a monitoring mode where the Icon system will not generate any controloutputs (such as thruster action). If sensors and position reference systems are available,
all signals can be monitored on the operator station(s). Feedback and status signals fromthrust devices and power system can be monitored as well. Entering standby from anyother Icon function will immediately stop any thruster action on thrusters actively usedfor Icon operations.
Start-up Function
When the system is activated (out of standby), the default start-up function is theJoystick function with manual position and manual heading control modes. However, itis possible to define other start-up functions such as yaw control fore.
Start-up heading control function (Manual/Auto) can also be preset in such way that theIcon system automatically enters fixed heading function when activated. The selected
start-up function will activate only thrust devices needed for the selected function, e.g.yaw control fore will activate only thrust devices located fore of midship.

Joystick Functions
The Joystick mode comprises all operational functions in surge, sway and yaw foroperating the vessel by means of the joystick device and manual/automatic headingcontrol. The following operational functions are available as standard for the Joystickmode:
Manual position and manual headingIn manual position and manual heading, theoperator manoeuvres the vessel by using the three-axes lever. The lever is used fordirect generation of surge and sway forces and yawing moment demands by the thrustdevices.
Auto heading (fixed or change heading)Reliable and accurate heading measurement(usually a gyrocompass) is required for activating this function. In auto heading, theheading of the vessel is kept automatically at the present heading setpoint value (fixedheading). Heading deviation is monitored and an alarm will be issued when movingoutside the boundaries. In auto heading, the heading of the vessel can be automaticallycontrolled from the present heading towards a new heading setpoint by a changeheading operation. A reference heading signal is generated to ensure a smooth andcontrolled heading change operation. In change heading, the system takes into account
the maximum rotation speed setting. Yaw control (fore/aft)If surge and sway axes are disabled (no control), the system will
control the yawing moment of the vessel only. This function can be used in cases wherefew thrust devices are enabled for active use, e.g. only one tunnel thruster fore and theother thrust devices are operated by manual levers. The heading function can then beeither in manual heading or auto heading (fixed or change).
Rotation pointWhen the selected rotation point is ForeorAft, the system willgenerate an additional sway force when the joystick lever is rotated. This swaycompensation force is generated to keep a pure rotation of the vessel around therotation point.
There is no feedback command involved for positioning the vessel in this operation.
The additional sway force is generated from the yawing moment generated by therotation of the joystick lever.
The operator can generate a new heading setpoint in many ways, such as:
Position device Heading wheelA new heading setpoint is easily generated byrotating the heading wheel in the desired direction, in increments relative to the presentheading setpoint.
Joystick device Push-buttonsDedicated push-buttons are available for theincrement or decrement of the heading setpoint relative to the present heading setpoint
GUIWhen using the graphical user interface, a new heading setpoint can be generatedby: Numeric input of a new heading setpoint Increment/decrement of the headingsetpoint relative to the present heading setpoint.
Whenever a new heading setpoint is defined, the new proposed heading is clearlydisplayed on the graphical user interface together with a numeric presentation. Thechange heading operation starts when the new heading setpoint is acknowledged by theoperator (by the Accept soft-button on the graphical user interface, or by the Accept
push-button on the joystick or positioning device).
Joystick Settings
The following settings are available for the Joystick mode:
Joystick sensitivity
Heading control gain

Maximum rotational speed (used in change heading operations)
Heading deviation warning and alarm limits
Thrust allocation settings, depending on the thrust configuration of the vessel (e.g. biassettings, thrust device combinator settings, maximum rudder angle, fixed direction onazimuthing thrusters).
Positioning Functions
The positioning mode comprises all joystick functions. In addition, the followingoperational functions are available:
Auto position (fixed or change position)The surge and sway axes are controlledautomatically. Reliable and accurate position measurements (e.g. satellite-basedsystems, laser-based systems, radar-based systems, hydro-acoustic systems) arerequired for these operations. The environmental conditions, the system control gainsettings and the number of thrusters active, determine the performance of the automatic
positioning. In fixed position, the vessel is kept automatically on the operator selectedposition setpoint. Position deviation is monitored and an alarm will be issued when
moving outside the boundaries. A change position operation can be initiated forautomatic moving of the vessel from present position towards the new positionsetpoint. Reference position signals are generated to ensure a smooth and controlled
position change operation. The surge and sway speed settings determine the responseand time to achieve the new vessel position. Change position operations requires theauto heading control to be active. A change position operation can be combined with achange heading operation at any time, either stepwise or in a coupled operation.
Mixed surge and sway controlThe operator can select combinations of surge andsway axes control (No control, Manual or Auto).
Manual/auto heading controlAutomatic heading control (fixed or change heading) isin most cases required in combination with any auto position mode.
Rotation pointThe operator can set the rotation (pivot) point, either by means of a setof pre-defined rotation points, or by a user-defined rotation point. The actual vessel
position, the position setpoint and the position deviation monitoring, are always relatedto the selected rotation point.
When the selected rotation point is ForeorAft, the system will generate an additionalsway force when the joystick lever is rotated. This sway compensation force isgenerated to keep a pure rotation of the vessel around the rotation point.
There is no feedback command involved for positioning the vessel in this operation.The additional sway force is generated from the yawing moment generated by therotation of the joystick lever.

Additional Positioning Functions
When in positioning mode, the following additional functions are available:
Wind compensationIf wind speed and direction measurements are available, theresulting wind loads acting on the vessel can be automatically compensated by the Iconsystem. This function is for rapid compensation of variations in wind loads acting on
the vessel. In most cases, the wind compensation feature will enhance the positioningperformance.
Positioning Settings
The following settings are available for the Positioning function:
Position control gain (low/medium/high)
Maximum surge and sway speed (used in change position operations)
Position deviation warning and alarm limits
4.3.2 Basic System Functions
Command Transfer
The Icon system provides means for transfer of command control between the differentoperator stations. Only one logical operator station (operator devices withcorresponding operator station display(s)) can be in command at a given time.Command transfer between Icon operator stations can be set-up to require a Give-than-take functionality.
Class Monitoring
In the Icon system, the operator can select the IMO DP class, which the system issupposed to be in compliance with. Based on this input, the class monitoring functionwill provide a complete overview of the system configuration regarding:
Sufficient sensors systems active
Sufficient position reference systems active
The power system and its configuration
Sufficient thrust devices active
DP system hardware components and data network status
Result of the online consequence monitoring function.
Online Consequence Monitoring
The DP online consequence monitoring is a class requirement for IMO DP 2 and DP 3operations. Based on the prevailing conditions, this function evaluates online the DPsystems ability to keep the vessel on the desired position, heading or track in a worst-case failure scenario, typically loss of one of the main power bus bars or equivalent.
The DP consequence monitoring function status is presented on the graphical userinterface, and an alarm will be issued when appropriate. For DP class 1 operations, thisfunction can be disabled.
Power Limitation
The Icon system includes power limitation. When activated, the power limitationfunction computes the available power for Icon operation and limits the thrust device

action to avoid power system overload.
Power system measurements, thrust device feedback and internal power models are usedto estimate available power on each power bus for thrust devices controlled by the Iconsystem. In cases with power limitation, i.e. insufficient available power to satisfy thecommanded thrust, the thrust orders are equally reduced.
Hence, the thrust reduction ratio is equal for all thrusters on the bus(es) with insufficientpower. Power limitation alarms are submitted for the limited thrust devices, andlimitation status is clearly indicated on the Icon graphical display.
Note: If desired, the Icon system can be configured not to utilise all the availablepower, to avoid an automatic start of the generators by the powermanagement system.
Power Interface Failure Detection and Failure Handling
The Icon system performs error checks on the power interface. Alarms are issued whenfailures on the power system interface are detected. These are I/O link failures, I/O unitfailures or other communication failures.
The value of estimated available power for Icon thrust devices will not be updated(freeze) when a power interface failure is detected, and the power limitation functionwill continue in a non-feedback manner.
Thrust Configuration
When the Icon system is activated (from standby), all available thrust devices areenabled for active use. During operation, a thrust device can be set to idle state. Thismeans that the system keeps command of the thrust device, but the thrust order is neutral(e.g. zero pitch).
When a thrust device is in idle state, the operator have the ability to take command ofthe thrust device on the dedicated lever, and operate it in combination with the remainingthrust devices actively used by the Icon system.
The Icon system will automatically adjust to the actual number of active thrust devices.If the requested mode of operation cannot be fulfilled due to reduced number of thrustdevices, an alarm will be issued. However, if an axis is set to No control, this alarmwill not be issued.
Note: When the start-up function is defined to be other than default (Joystick
mode with manual position and manual heading), the system will activateonly the thrust devices required for the selected start-up mode.
Example: If the start-up function is defined to be yaw control fore, only forethrust devices are activated.
Built-in Trainer
The purpose of the built-in trainer is to provide operator training and systemfamiliarisation as an integral part of the Icon system. The built-in trainer comprises avessel simulator and a dedicated graphical user interface for set-up of the simulatedoperational conditions. The simulator generates realistic dynamic behavior of

environmental conditions, thrust devices, power system, and resulting vessel motion.
The simulator sends artificial measurements and feedback signals to the Icon system thatin real operations are received from the sensor systems, position reference systems,
power systems and thrust devices. Based on these inputs, the Icon system computesthrust device order signals. In training, these signals are sent back to the vesselsimulator, not the real thrust devices.
Note: The built-in trainer can only be started when the Icon system is in standbymode. When operating the system with the trainer, this is clearly indicatedon the graphical user interface.
4.3.3 Optional Functions
An Icon system can be delivered with the following optional operational functions:
Waypoint tracking
Target tracking
Towing.
An Icon system can be delivered with the following optional system functions:
Capability analysis.
Waypoint Tracking
Waypoint tracking is enabled from the Operation panel.
Waypoint tracking is a low speed tracking function that permits the vessel to
automatically move along a track defined by a list of pre-defined waypoints.
Each waypoint is associated with a set of data. The acceptance radius determines wherethe vessel starts turning towards the next waypoint, also known as the wheel-over point.This turn occurs on an inscribed circle. All waypoints are connected by straight tracklegs. The waypoint track thus consists of inscribed circles in waypoints and straight lines
between them.
The radius of the inscribed circle is called turning radius. The turning radius isdetermined by the acceptance radius and the previous and next waypoint. Theacceptance radius can be specified directly or the system can calculate it from the vesselROT and speed settings.
The wheel-over point is where the waypoint track starts the turn towards the next
waypoint.

Positivevalues are to the right of the track (when following the waypoints in an ascending order).This will increase or decrease the turning radius of each turn depending on turn directionand sign of offset value.
Offset (geographic)
The entire track is moved a specified distance in a specified direction relative to North.The geographical offset can also be specified in relative North/East distance. The newtrack will be an exact copy of the original track.
Track validation)
All changes to a track are validated by the system to make sure that waypoints arelocated sufficiently far away from each other. When a relative offset is selected, theacceptance radius of each waypoint is checked to validate the new turning radius.
Activate Low-Speed Waypoint Tracking
To enter low-speed tracking heading must be fixed (Auto mode) and the yellow curvemust be shown on the 3D scene. After starting the tracking operation, surge and swaywill enter Change mode (regardless of previous modes). The rotation point must always
be at the centre while in tracking, so the system will automatically force it to (0, 0) whenthe function is activated by the operator. (Note that a warning will be given if the system
changes the rotation point).
Deactivate Low-Speed Waypoint Tracking
The vessel will stop at the last waypoint when it has completed the track. The DP systemwill then enter Fixed Mode and will be positioned at this location until a new commandis given.
During operation, low-speed tracking is aborted by using the Exit button on theOperation Panel or by selecting a new (or re-fix a) position control mode from controlmode menu in GUI or from control mode buttons on the Positioning Device twice. Thevessel will then go to the control mode selected, Fixed, Manual or Mixed.

Target Tracking
Target tracking is a function that permits the DP vessel to track another object, a remoteoperated vehicle or another vessel, in a fixed distance (range) and direction (bearing).Relative position reference systems are used to measure relative distance to the trackedobject, typically laser or radar based systems for surface objects and hydro-acousticsystems for sub-surface objects. The system defines the target by the measured reflector
(above surface) or transponder(sub-surface) distance and direction readings.
Single Mode
In single mode, one reflector/transponder is enabled and set as target. Heading andglobal position position measurements must be available, surge, sway and yaw must becontrollable. The system will enter auto trackmode in surge and sway and auto headingmode in yaw, regardless of previous modes.
If a reaction radius is used, the position setpoint will be updated only when the targetmoves outside the pre-defined reaction radius. The heading setpoint is not dependenton the target movement. During target tracking operation, the heading setpoint can bechanged by the operator.
If no reaction radius is used (direct follow), the position setpoint will be continuouslyupdated as the target moves.
Note: During normal operation, the relative position and heading setpoints canbe changed at any time.
Multi Mode
In multi mode, two or more reflectors/transponders are enabled and set as target.Heading and global position measurements must be available, surge, sway and yaw must
be controllable. The position and heading modes depend on the tracking mode:
Follow position: position will be in auto trackmode, i.e. when target moves the DPvessel position setpoint depends on target movement (constant range to all usedtargets). In this mode, the target heading is not taken into consideration.
Follow heading: position may be in either autoorjoystick, while heading always willbe in auto track mode, automatically changing DP vessel heading with targetorientation changes. In this mode, the distance to the target is not taken intoconsideration.
Follow heading and follow position: both position and heading of the DP vessel
tracks the movement and orientation changes of the tracked object.

Important
The modes with reaction radius are designed to follow a target that occasionally movesoutside the specified circle, but mainly stays within it. If such mode is used to follow atarget that is moving close to constant speed, there will be a lag between the actual vessel
position and the setpoint. The reason for this is that the vessel should be able to stop atthe setpoint without overshoot if the target suddenly stops.
The vessel velocities (surge, sway, and rate of turn) will also be limited by the values setby the operator in position and heading settings.
If a more aggressive following (without a constant lag between the actual position andheading and the setpoints) is wanted, one of the direct following modes should be used.
In these modes, the vessel velocities will not be limited by the operator set values. Thesystem will do its best to go as fast as the target movement requires.
Towing
During a towing operation, the operator can add a bias force in the forward direction tocompensate a near constant load. A constant bias force can only be added when the surgeaxis control mode is set to Joystick. The bias force will automatically be set to zero bythe system if the Joystick mode is exited. The joystick lever can be used incombination with the constant bias force to adjust the total surge force order, i.e. theconstant bias force can be neutralized by moving the joystick in negative surge position.
Towing Settings
The bias surge force can be entered numerically or incrementally up and down from theGUI.

4.4 Signal Processing Functions
All measurements to the Icon system have to pass several levels of testing andprocessing before being utilised in the control of the vessel, see following table. Alarmswill be issued if the Icon system detects any errors in the input signals at any level.

The signal processing functions available are described in more detail in the followingtable:
Function Desciption
Interface check This function checks that the interface to all sub-systems and devices are workingcorrectly. Loop and range checks on signals are performed, as well as hardware and
protocol checks for serial lines and network communication. Possible interface errors
will result in Unavailable status for the specific device in the GUI.
Device specific checks This function device specific checks on sub-systems and devices.
Range check
This function checks if all input signals to the system are within the system specified
range.
Out of range status will result in auto disabling of sensors and position reference
systems.
Out of range status on power signals will cause the signal to be limited on max/minlimit.
Frozen signal check This function checks that the signals from sensors and position reference devices are
not frozen. If a signal is unchanged or changes very slowly for an abnormal long
period of time, a signal freeze alarm is issued.
Wildpoint check
This function checks the signals for wildpoints, i.e. single values that are unexpected
and does not follow the curve for the other values. Signal wild points are replaced,
and alarms issued in the GUI.
Step check This function checks the signals from the devices for unacceptable steps. If
unacceptable steps are found, the device will be disapproved until the signal
becomes normal again. For large signal steps the device will be automatically
disabled.

High variance check This function checks if there are high variances in the output values from sensors and
position reference devices. If there are high variances, the device will be disapproved
until the signal becomes normal again.
High dynamics This function checks the signals for high dynamics. For abnormal signal dynamicsthe device will be disapproved until the signal becomes normal again. For extreme
signal dynamics the device will be automatically disabled.
Position standardisation This function performs checks on raw measurements, standardized measurements
and aligned measurements for position reference systems.
Out of range and Frozen signal checks are performed on the raw measurements.
The raw measurements are mapped to the standardized vessel position.
The Wildpoint, Step, High variance and High dynamics checks are performed on
standardized positions.
Position alignment
This function is used for alignment of the position reference systems to provideposition measurements that are referred to a common zero frame.
Basically, each GNSS define their own zero point, and the local position references
are aligned with the GNSS zero frame. A GNSS can also be aligned if the position
deviates from another more reliable GNSS.
The position references can be re-aligned from the GUI when required.
If there are no GNSS available one of the local position reference systems will define
the zero frame.

Differ and voting reject
These functions performs divergence checks.
Differ check is performed when two devices of the same type are enabled. If the
difference between the signals of the two devices exceed a predefined limit, a Differ
alarm is issued. If one of the signals clearly moves away from the other, that devicewill be Differ Rejected.
Voting Reject is performed when three or more devices of the same type are
enabled. If the difference between the signals of one device compared with the
others exceed a predefined limit, the device is rejected / disapproved until the signals
becomes normal again.
Divergence checks are also performed on disabled devices. The disabled devices
are compared with the enabled devices.
Weighting This function automatically makes the output values from functional and enabled
sensors and position reference devices affect the system in relation to the quality of
the output signal.
Weighted signals will only be calculated for multiple devices of the same type.
Manual scaling This functions is used to manually control how much specific sensors and position
reference devices affects the system
