System Overview

The SceneScan System is a high accuracy rotating laser Sensor that provides positional information to allow automated approach and/or station keeping relative to a structure or vessel. It is designed to be semi-portable and straightforward to operate.

Its key elements are:

The SceneScan Sensor: The marine grade SceneScan Sensor is mounted on the

•

vessel (typically on the wheelhouse) as required. The SceneScan Sensor emits eye-safe infrared light and detects the reections received back from one or more designated structures or vessels.

The SceneScan Client Software: There are two key pieces of software:

•

The SceneScan Service Interface: The SceneScan Service Interface is used

•

for system installation and maintenance.

The SceneScan Dashboard: The SceneScan Dashboard generates a visual

•

representation of the scene detected by the SceneScan Sensor. It gives the DP Operator control of the system and the data stream being fed to the DP system.

Both pieces of software run under Windows™ on a Type 3 Marine Processor or other computer providing the minimum system requirements (See page 55).

The SceneScan system operates dierently to other local position reference systems in that it does not require any type of target to be placed on the asset that is being approached or used for station keeping.

It scans the vessel or structure and produces a map. This map is compared to the current scan by the SceneScan Sensor navigation algorithm, which is used to track a local position.

Start Up and Shut Down

Start Up

To Start SceneScan Dashboard

1. Ensure that the SceneScan Sensor is powered on.

2. Double-click on the SceneScan Dashboard icon. (Or run the SceneScan Dashboard from Start > All Programs > Guidance Marine Ltd > SceneScan > SceneScan Dashboard).

3. The Dashboard display screen will appear. If the Sensor is currently suspended, the main part of the screen will be greyed out. Click on the Resume button in the side bar in order for the Sensor to begin scanning and for the results to be displayed on the screen. If the Sensor was already scanning, then the current scene will be displayed.

Shut Down

To Suspend, Exit or Disconnect

1. Click on the Guidance button in the lower left corner of the screen.

This will reveal buttons in the side bar as follows: (see right).

Suspend - Places the Sensor into a ‘sleep mode’. The rotor ceases spinning and the

•

scanner tilt returns to a xed state. The unit can be returned to full operation via a Resume command from the Dashboard. This mode is suitable for use when travelling between locations.

Disconnect - Ceases communications between the Dashboard and Sensor and

•

causes the main part of the screen to be greyed out. Does not cause the Sensor to stop spinning or tracking the scene.

Suspend And Exit - Places the Sensor into the same ‘sleep mode’ as the suspend

•

command (discussed above) and also closes the SceneScan Dashboard program.

Exit - Closes down the Dashboard without aecting the Sensor.

Targetless Tracking

Overview of Targetless Tracking

Traditional relative positioning Sensors rely on placing targets on the structure or vessel which the Sensor then detects and can report a position relative to. SceneScan removes the requirement to place targets into the scene and instead provides tracking information relative to natural or man-made structures within the Sensor eld of view. It achieves this by matching its current observation of the scene against previous observations of the same scene, in order to determine the motion of the Sensor between observations.

In order to maximise the performance of this approach, the Sensor rst calculates the most reliable and informative section of the scene to track o. This step is called tilt optimisation, and involves the Sensor scanning through various sections of the scene to work out which tilt angle to track at.

Once a suitable section has been selected the system starts tracking and reporting the position of the Sensor within the scene. As the Sensor moves and the view of the scene changes, the Sensor will automatically update its model of the scene while tracking without any need for user intervention.

Blanking Zones

Warning: Before starting tracking it is critical that Blanking Zones have been

!

correctly congured to mask out regions of the scene that we do not wish to

track.

Two types of blanking zone can be congured on a SceneScan system:

Fixed Blanking Zones – These can be exclusively congured using the SceneScan

•

Service Interface. Fixed blanking zones are the Vessel Blanking Zone (Vessel Parameters) and the Static Blanking Zones.

Operating Blanking Zones – These can be amended in the Dashboard when the

•

system is running, even during tracking. Operating blanking zones are the Dynamic Blanking Zone and the Minimum Range Filter.

For information on how to set Blanking Zones see the following sections:

Operating Blanking Zones on page 24

•

Vessel Parameters on page 62

•

Static Blanking Zones on page 65

•

l

Targetless Tracking (Continued)

Tracking Overview

Start Tracking

Once Blanking Zones have been congured the operator can command the Sensor to start tracking.

SceneScan Tracking is inuenced by the operator’s choice of tilt mode (see the Scanner Tilt Controls section on page 25 for further information):

Auto - When starting tracking, the scanner will automatically “sweep” through a

•

range of angles to determine the most stable scene for tracking purposes.

Manual - This mode is used to manually tilt the optics to point at the desired part of the

•

scene. When starting tracking, the scanner will use the currently selected angle and no “sweep” will be performed.

Once a suitable tilt angle has been chosen tracking will start and the scanner tilt angle will automatically adjust as the range to the asset changes. This is to ensure that the same part of the scene is used throughout the tracking session.

Scene Reference Point

Once the Sensor has started tracking, it will start reporting its position relative to the Scene Reference Point.

By default SceneScan will select the centre of the tracked scene for the scene reference point, with a heading of 0°.

This behaviour should be sucient for most users. However users are also able to edit the Scene Reference Point, altering both its position and heading. This might be done to align to the heading of a tracked vessel, or to position oneself against the edge of a platform or quayside.

Enabling DP Output

Once tracking, the Dashboard will display tracking and scene data, but the Sensor will not output a DP feed. The reason for this is to allow the operator to review the detected scene, and to set a Scene Reference Point of their choice before enabling DP Feed output.

When the operator is happy with the tracking data displayed on the Dashboard the DP output can be enabled and the Sensor will start to report valid position telegrams to the DP system.

Warning: Changing the Scene Reference Point will disable the DP Feed. This is done because altering the point can dramatically alter the output from the DP

!

Feeds. The DP Feeds must be re-enabled by following the below procedure.

Screen Layout

The SceneScan Dashboard screen is split into three distinct sections, these are:

1. Main Screen and Bird's

•

Eye View (BEV) (see page

14)

2. Side Bar (see page 16)

•

3. Menu Pane (see page

•

18)

l

13

Screen Layout (Continued)

Main Screen and Bird's Eye View (BEV)

The circular BEV shows the observable scene and Scene Reference Point relative to the Sensor and vessel.

The Figure on the right labels elements on the BEV and its periphery.

Vessel Outline

The Vessel Outline in the centre of the BEV represents the ship on which the SceneScan system is located, and the red dot denotes the SceneScan Sensor. The rotating fan-shaped symbol represents the laser beam emitted by the rotor as it turns.

The whole BEV can be rotated in steps of 90° to allow for dierent positions of the monitor. The size and shape of the vessel outline and the position of the Sensor’s red dot within it can be congured using the SceneScan Service Interface.

Blanking Zone

The Blanking Zone is an area dened by the user in order to blank-out parts of the scene that should not be used for tracking. During each revolution of the Sensor, when the rotor enters this sector the laser stops pulsing. The Blanking Zone is adjusted to suit the current operating conditions.

Range Circles

The Range Circles are a visual guide that help to show the distances between the Sensor vessel and the detected reections. Distances are given in metres from the centre of the Sensor.

Radial Markers

Around the circumference of the BEV are marked angles in degrees, clockwise from the bow of the vessel.

l

Screen Layout (Continued)

Scene Data

The Scene Data shows the scene detected by the SceneScan Sensor.

Note: The Scene Data can be constrained to a traditional circular BEV, or expanded to ll the central area using the Toggle BEV Shape button on the Hotkeys Tab, or by pressing F8.

Scene Reference Point

The Scene Reference Point shows the point within the scene about which SceneScan is tracking.

Bearing and Heading Tags

The bearing tag and the heading tag are displayed when tracking is in progress, to indicate the target’s bearing and the vessel heading on the Radial Marker.

Data Logging Indicator

This symbol is displayed when data is being logged to disk.

Zoom Control

Allows a user to zoom in (+) and zoom out (-) of the BEV. Click on the left-hand side of the control (marked '-') to zoom out of the display and on the right-hand side ('+') to zoom in.

Hotkeys Tab

The Hotkeys Tab is located on the right hand edge of the main pane. Clicking on the tab will open the Hotkeys Menu.

System Status

This consists of two elds:

Primary

The primary status display is positioned in the upper-right corner of the main pane. It indicates the current status of the system, for example System Running Normally or System Suspended.

Secondary

The secondary status display is positioned in the lower-right corner of the main pane. It displays a ashing message for a number of seconds in order to conrm an action taken by the user. It can also display a persistent, static message if there is a communications problem.

Menu Pane

The Menu Pane, located across the bottom of the SceneScan Dashboard Screen, is not always visible. It appears when one of the Tracking, Tilt or Advanced buttons near the foot of the Side Bar are pressed, which causes the Bird's Eye View (BEV) to contract towards the top of the screen. Clicking the same button for a second time causes the Menu Pane to disappear and the BEV to be restored to full size.

l

18

Tracking Information Quality

Once tracking is under way the Data Quality Bar indicates the level of condence the system has in the quality of the scene data that is being acquired. The greater the size of the lled portion of the Data Quality Bar, the greater the level of condence in the information.

The colour of the Data Quality Bar and positional data also reects the level of condence: RED, YELLOW or GREEN, with GREEN meaning highest condence.

When tracking, the Data Quality Bar and positional data disappear and are replaced with a warning message if the system loses track of the scene.

l

19

Display Settings

To provide ample visibility during daytime operation and to limit glare during night shifts, SceneScan Dashboard oers two display settings: Day Mode and Night Mode. In either mode the brightness can be further adjusted by the Screen Brightness control.

To change day/night mode and adjust brightness:

1. Navigate to Advanced > Display Options > Display Settings.

2. Click on one of the Day / Night Mode symbols.

3. Click on the left side of the Screen Brightness control to dim the screen and on the right to make it brighter.

Alternatively, to toggle between day and night mode, use the keyboard shortcut F9 or the Toggle Day/Night Mode button in the Dashboard Hotkeys panel.

20

Display Settings (Continued)

The central BEV can be toggled between a traditional circular BEV, and a full scene mode. Press F8 to toggle modes, or use the Toggle BEV Shape hotkey. The latter is useful when viewing complex scenes such as harbours.

The BEV can be further expanded to a full screen mode by pressing F11, or using the Toggle Full Screen hotkey

This mode maximises the space available for tracking. Whilst this removes the Side Bar from view, it can be restored by pressing F11 again, or clicking the Tab along the left edge of the screen.

l

21

Vessel Orientation

SceneScan Dashboard supports four dierent layouts of the Bird’s Eye View so that the operator can choose the one which best represents the vessel’s surroundings.

To set Vessel Orientation

1. Navigate to Advanced > Display Options > Layout.

2. Click on the vessel outline that points in the required direction.

Note: Changes made to the vessel orientation using the Dashboard are temporary and will revert back to the default setting when the Dashboard is restarted� The default orientation can by changed from within the SceneScan Service Interface�

Note: This is a Dashboard display function only and will not affect the DP output�

Operating Blanking Zones

Dynamic Blanking Zone

The Dynamic Blanking Zone is used to mask a segment of the scan rotation. When the scanner passes through the dynamic blanking zone, the laser is switched o to prevent any unwanted reections.

N.B. Even if the Sensor has a clear 360° view, there must be a dynamic blanking zone of at least 23°. The user interface will not allow smaller blanking zones.

Generally the dynamic blanking zone will not need to be changed. However, there may be occasions when it is necessary to adjust the dynamic blanking zone, for example to mask out another vessel in the Sensor eld of view..

Note: Up to four additional static blanking zones can be congured from within the SceneScan Service Interface. These are used to mask segments of the scan rotation that are obscured by the vessel’s superstructure. See the Static Blanking Zones section on page 64 for further information.

Setting the Dynamic Blanking Zone

The start and end of the zone can be set to any positions around the circle to the nearest degree, subject to the minimum and maximum sizes of the zone (see red box below).

To dene the Dynamic Blanking Zone

The Dashboard needs to be in Command Mode to make changes to the dynamic blanking zone.

1. Click one of the dynamic blanking zone handles and, holding down the left mouse button, drag to the desired position. Alternatively - on a touchscreen - touch and drag. As the handle is moved, its current position (in degrees clockwise from the vessel bow) is displayed in blue numerals outside the perimeter of the circle.

2. If required, drag the second zone handle in the same way.

3. The Apply-Cancel buttons will have popped up after step 1. Click on the Apply button to set the dynamic blanking zone, or on Cancel to restore the dynamic blanking zone to its previous state.

The Dynamic Blanking Zone must cover at least 23° but no more than 337°. The user interface will not allow larger blanking zones. It is not possible to change the blanking zone when in full screen mode.

Range Filters

The Range Filters function on the Power menu allows the user to set minimum range. Any objects at a shorter range than the range threshold will no longer be visible to the Sensor and so will be excluded from tracking. This mechanism is useful when a structure/vessel other than that being used for tracking cannot be eliminated by means of the dynamic blanking zone function alone. It can be used at any time, even during tracking.

The range threshold can be adjusted between 1 and 70 metres by clicking on the end of the lter bar marked ‘+’ or ‘-’ as required. A corresponding exclusion zone is shown in the centre of the BEV.

l

24

Scanner Tilt Controls

The scanner tilt mechanism automatically compensates for the pitch and roll of the vessel caused by wave motion.

Motion Sensors and a tilting optics mechanism ensure that the scanning optics remain at the correct level to see the scene.

16° Scanner Tilt

Scanner Tilt Modes

The scanner can be operated in either of the following tilt modes:

Auto - When starting tracking, the scanner will automatically “sweep” through a range of

•

angles to determine the most stable scene for tracking purposes.

Manual - This mode is used to manually tilt the optics to point at the scene. For

•

example, when station-keeping close to a platform where the superstructure is high up and the SceneScan beam must be tilted upwards. When starting tracking, the scanner will initially use the currently selected angle. No “sweep” will be performed. Manual Tilt can also be used to visually survey the scene around the vessel without tracking.

Once a suitable tilt angle has been chosen tracking will start and the scanner tilt angle will automatically adjust as the range to the asset changes. This is to ensure that the same part of the scene is used throughout the tracking session.

When the Sensor is rebooted the tilt mode defaults to Auto.

The current tilt mode and leveller angle are displayed in the ‘Tilt Mode’ section of the Side Bar.

To change the scanner tilt mode and leveller angle

1. Click on the Tilt button in the Side Bar.

2. Select the required mode and click on the Apply button to conrm.

3. Click on the +/- buttons to adjust the angle.

4. Click on the Apply button to conrm your changes.

Once the scanner starts tracking, it is not possible to change the tilt mode or leveller angle

Sidebar Tilt Mode section

Spirit Level

The Spirit Level control, on the left hand side of the Tilt pane, displays the roll and pitch of the vessel as measured by the Vertical Reference Unit within SceneScan. The graphical display represents the roll and pitch angles in the same manner as a bull’s eye spirit level. The current values are displayed in text at the bottom of the control. A ship outline is shown in the background to indicate orientation relative to the vessel.

Tracking

To Start Tracking

1. Ensure that the Dashboard is In Command (see

Command Mode).

2. Press the Start Tracking button.

3. Press Apply on the Apply/Cancel pop-up.

Tilt Optimisation will start. The angle chosen will depend upon the current mode:

Auto Tilt - The Sensor will sweep through all possible tilt angles

•

to determine the optimum angle for the scene tracking. The left pane of the dashboard will show the progress of this operation.

Note that the Sensor may not nd a viable scene for tracking. This can occur (for example) when in open water. In this scenario the Sensor will continue Tilt Optimisation by repeating the sweep process indenitely until a suitable / adequate scene is found. This process can be halted by Stopping Tracking (see below).

Manual Tilt - The Sensor will use the current tilt angle for tracking.

•

Tracking will start once a tilt angle has been selected by the Sensor in Auto Tilt mode, otherwise the operator / user selects the tilt angle.

To Stop Tracking

While tracking is in progress, a Stop button is nestled within the Tracking button. Click on the Stop button to stop tracking.

l

26

Tracking (Continued)

Adjusting the Scene Reference Point

Scene Reference Point

This is the point within the scene that SceneScan will report its position relative to. By default SceneScan will select the centre of the tracked scene as its Scene Reference Point, with a heading of 0°.

This behaviour should be sucient for most users. However, users are also able to edit the Scene Reference Point, altering both its position and heading. This might be done to align to the heading of a tracked vessel, or to position oneself against the edge of a platform or quayside.

To Edit the Scene Reference Point:

1. Ensure that the Dashboard is In Command (see In Command Mode on page 33)

and is Tracking. It does not matter whether DP Feed is enabled or not.

2. Press the Tracking button to bring up the Tracking Menu.

3. Press the Edit Tracking button.

4. Now the Scene Reference Point can be edited as follows:

1. Left Click on the scene with the mouse to move the reference point to the clicked location. If Snap To Scene is selected then clicking the scene will move the reference point to the closest point of Scene Data. This is useful when trying to align with the edge of a structure.

2. Right Click + Drag on the scene with the mouse to rotate the reference point, altering its heading.

3. Select Rotate to change the mouse behaviour such that Left Click + Drag now rotates the reference point. This is useful for touch screens.

4. Use the Align Heading control on the Tracking Menu to precisely control the heading.

Note that Edits are not live - changes made will only take eect when the “Apply” button is pressed. The “Cancel” button will undo any pending changes.

Warning: Changing the Scene Reference Point will disable the DP Feed. This is

!

done because changing the reference point can dramatically alter the output from the DP Feed. The DP Feed must be re-enabled by following the below procedure.

Note that pressing the Reset button at any point during the edit will undo your changes without Cancelling your Edit. In addition, the zoom controls can still be

5. Once you are done, press Apply on the Apply/Cancel pop-up.

used to alter the zoom level of the central BEV while selecting the reference point.

l

27

Tracking (Continued)

Enabling DP Output

Once tracking, the dashboard will display tracking and scene data, but the Sensor will not have the DP Feed enabled. The reason for this is to allow the operator to review the detected scene, and to set a Scene Reference Point of their choice before enabling DP Feeds.

To Enable the DP Feed:

1. Ensure that the Dashboard is In Command (see Command Mode).

2. Press the Enable DP Feed button.

3. Press “Apply” on the Apply/Cancel pop-up.

The DP Feed will now be enabled, and the dashboard will change to indicate that tracking is fully enabled.

Tracking Lost

If the SceneScan loses track then the following message will be displayed in the coordinates pane:

At this point the operator will need to stop and restart tracking.

Manual Tilt Mode

It is highly recommended that Auto tilt mode is used to start tracking when using SceneScan. However, if a situation is encountered where tracking performance is unacceptable when using Auto tilt mode then the option is available to manually select a tilt angle.

Here are some general guidelines to follow when using Manual tilt mode:

1. Try to select regions of the scene that have a high level of vertical consistency.

2. If the vessel will be maneuvering around the structure then consider whether structure on dierent sides of the structure are also vertically consistent.

3. Watch the BEV to see how consistent the image of the structure is before starting tracking. If the scene is changing dramatically then tracking is unlikely to be stable and a dierent tilt angle should be chosen.

4. Small tilt angles will generally provide better tracking performance. This is particularly true when the range to the asset will be changing signicantly during a tracking session.

5. When tracking o a rig, substructure tends to provide more robust tracking performance than superstructure.

Vertical features visible from multiple sides of a rig are good when wanting to transition around the asset.

Dierent features closely located at slightly dierent elevations are oor targets to track o. Protruding features of the assest are also not advised to track o.

The relative positions of the SceneScan vessel and the Scene Reference Point can be expressed either as Range and Bearing values, or as 'A' and 'B' positions on a rectangular coordinate frame.

The position of the tracked scene can be displayed as Range/Bearing/Heading or A/B/ Heading.

Users can select the required mode by clicking the appropriate tab above the Data Quality area:

Range, Bearing & Heading

Range, Bearing and Heading (R/B/H) mode displays the distance and the bearing of the Scene Reference Point from the Sensor. The radial markers around the outside of the BEV are zeroed in line with the vessel bow and a magenta tag marks the bearing which is the angle of the target clockwise from the bow.

A purple tag represents the heading, which is the angle of the vessel bow clockwise from the heading axis.

SceneScan Dashboard - Monitoring Mode

SceneScan supports multiple Dashboards running simultaneously on the same system. No more than one of these can be in Command mode at any given time; the others are in Monitoring mode.

When the Dashboard is running in Monitoring mode, the controls relating to the Dashboard itself will be active, but those relating to the SceneScan Sensor will be disabled. A Monitoring Dashboard displays the same scene as the In Command Dashboard. It cannot initiate or stop tracking operations, nor alter the power control, nor tilt settings.

Examples of inactive controls in Monitoring Mode

To switch a Dashboard from In Command mode to Monitoring mode:

1. Click on the Guidance button.

2. Click on the Relinquish Command button.

l

32

SceneScan Dashboard - In Command Mode

When the SceneScan Dashboard is running in Command mode all control functions are available. Any changes made to the tracking or Sensor-related settings at the In Command Dashboard will be visible on the screens of the Monitoring Dashboards. On the other hand, display options such as Screen Brightness or Zoom level can be set dierently on each individual Dashboard, whether it is Monitoring or In Command.

When the In Command Dashboard is used to suspend the SceneScan Sensor, a message will appear on the screens of the Monitoring Dashboards indicating that the system is suspended. The same message is displayed if a Dashboard is opened whilst the Sensor is suspended (See Start Up and Shut Down on page 10).

In this state, clicking the Resume button on any Dashboard will automatically put that Dashboard In Command. Clicking Exit will close that individual Dashboard only.

Whenever the system is running, a Monitoring Dashboard can be promoted to In Command as shown on the right.

Examples of active controls only available in Command mode

To switch a Dashboard from Monitoring mode to In Command mode:

1. Click the Guidance button.

2. Click on the Take Command button.

When the Dashboard is in Command mode, it will automatically switch to Monitoring mode when another Dashboard takes command.

Low Temperature Operation

Introduction

The SceneScan Sensor is a precision electromechanical device with hardware components that, out of necessity, are mounted in an external position on a vessel’s superstructure. It is recognised that industrial marine operations may subject these components to harsh environments, including low temperature.

The SceneScan hardware complies with the requirements of IEC 60068-2-1 and is able to operate for prolonged periods at temperatures down to – 25°C provided that certain operating conditions are maintained.

Operating Conditions

The following recommendations are made for low temperature use:

If it is necessary for the system to be switched on after a prolonged period at

•

temperatures below -5°C (and down to – 25°C) the Sensor will warm itself, but will require 2 hours to reach optimum operating condition.

If the unit is switched on after a period at temperatures between -15 to -25°C it will

•

not communicate with the Dashboard and the rotor will not rotate until the internal temperature of the base unit rises above -15°C.

When the system is not in use (i.e. un-powered or suspended) the Sensor should be

•

protected by means of a suitable insulating and protective cover to prevent the external build-up of ice.

Technical Considerations

The SceneScan Sensor uses a sophisticated rotating infrared laser range-nder to

•

accurately measure the distance and bearing to features in the scene. Movement sensors allow mechanically driven optics to compensate for vessel motion due to wave action. The internal mechanism may become disabled if it is allowed to cool in a low temperature environment.

A safety interlock prevents activation of the range-nder laser if the scanner rotor head

•

stops or is prevented from rotating by ice build-up.

l

35

Working with Alarms

During operation, the SceneScan system produces an audit trail of event messages. These range in increasing order of severity from: Information, Warning, and Error to Fatal. As these alarms are raised, the Dashboard lists them within the Alarms pane.

Click on any alarm to display details about it in the right-hand section of the Alarm pane:

The severity and current state of an alarm are reected in its colour and shape:

Information—grey symbols

•

Warning—orange symbols

•

Error and Fatal—red symbols

•

The ‘Play’ symbol indicates that an alarm condition is persisting. These are known as Active alarms. An alarm in this state will show a Start time but not a Stop time.

The ‘Stop’ symbol means that the alarm condition no longer exists, i.e. it has Stopped, therefore the alarm will show both Start and Stop times.

The ‘Pause’ symbol indicates an instantaneous alarm. In this case, the Start and Stop times are identical.

When an Error or Fatal alarm is raised, the Advanced button glows red. Once the glowing Advanced button has been clicked, it will take you to the Alarms pane. If the pane is closed, the Advanced button returns to its normal grey shading.

Fatal Alarms indicate a serious problem with the SceneScan system. Users should review the alarm details and follow any recommendations listed. Typically these involve powering down the Sensor and restarting it, along with restarting the Dashboard. If necessary contact Support.

Filtering Alarms

A lter is available to suppress the display of particular alarm by severity. By default, the lter is activated and causes information messages to be hidden.

Click on the Alarm Filter button to toggle between activated and de-activated .

Click on the Filter Selection button to choose which types of alarm are to be ltered out:

Alarm types that are ticked are always displayed in the alarms list; un-selected types are hidden when the lter is activated.

l

36

Dynamic Positioning Feed

The Dynamic Positioning (DP) Feed is the data that SceneScan transmits to the vessel’s DP system. SceneScan supports several dierent data message formats and it is important that SceneScan and the DP system are both congured to use matching formats. However, this cannot be done from the Dashboard; in order to change the SceneScan DP settings, use the SceneScan Service Interface (see page 66 for the Dynamic Positioning Feed

Conﬁguration and See page 71 for the DP Message Types.

The state of the Sensor’s DP output channel, the message format used and the most recent data output can be viewed on the Dashboard.

To View DP Feed Details:

1. Click on the Advanced button on the side bar.

2. Click on the DP Feed button on the Menu Pane.

l

37

Network Communications Settings

The Comms Settings Menu Pane displays the conguration of communications between the Dashboard and Sensor. This menu only changes the local dashboard record of the Sensor IP address. Changing the Sensor's IP address (stored in the connect.ini le) is NOT possible from the dashboard but IS possible from the SceneScan Service Interface Network Cong tab 'Sensor on-board network conguration' section (See page 59 for the Network

Communication Settings).

To View the Network Comms Settings:

1. Click on the Advanced button on the sidebar.

2. Click on the Comms Settings button on the Menu Pane.

To Modify the Dashboard’s Record of the Sensor’s IP Address:

1. Navigate to Advanced > Comms Settings.

2. Click on the Edit button.

3. Modify the IP Address eld as required.

4. Click on Apply to conrm.

l

38

Data Logging

Manual data logging button enabled. Manual data logging not active.

During tracking, the system automatically generates a set of operation logs that can be analysed by a service engineer to diagnose any system faults. Logging can also be started manually, when the system is not tracking (see below).

When logging is in progress, the following symbol is displayed in the bottom left-hand corner of the main pane.

Logs can be exported and e-mailed to Guidance Marine (customerservices.uk@ guidance.eu.com) or your DP supplier in the event of a problem.

Where to Mount the Sensor

Sensor Mounting Locations

The SceneScan system is designed for permanent or semi-permanent installation on-board a vessel. Often, a custom-fabricated plinth is used to provide the optimum height and location for mounting the SceneScan Sensor.

On all types of vessel the Sensor should be mounted:

With an unobstructed view in the expected direction of the scene (structure or vessel).

•

Well above sea level to prevent swamping or immersion.

•

On a at, rigid, horizontal surface able to support 30kg and receive 4x M8 xing bolts.

•

Allowing for easy access to the connector board and Sensor Information Display.

•

Clear of VHF emergency band antennae, S-band and X-band ship’s radars (5 meter

•

minimum horizontal separation from RF sources (VHF, S and X band) and ideally vertical separation of one deck).

Clear of likely emissions from exhausts or other particulate sources to reduce the need

•

for cleaning the optical windows.

The eld of view o the vessel should be clear of retroreective material

•

Exhaust emissions contain particulates which will degrade the optics.

The Sensor should be mounted with the Access Cover available for easy maintenance (see page 9). Any deviation from the centre-line alignment must be corrected in the SceneScan Service Interface. See the Bearing Oset section on page 61 for further information.

A typical mounting position is above the wheelhouse for a vessel with a superstructure like that of a platform supply vessel.

Cable Specications

The SceneScan system is usually supplied without the cables that are necessary to connect the Sensor to the DP system and the Client Software computer(s). Guidance recommends that exible multicore cables are used in all applications. Cables should meet the requirements of IEC 60228 Class 2 or Class 5. Cables must be supplied and tted by the installer to match the particular requirements for each vessel. All cables should be properly secured.

The cable glands will t cables from 7-13mm diameter.

All cables should be

• External marine standard including UV and chemical resistance

• 500V rated voltage

• Diameter 7-13mm

• Operate between -30°C to +70°C.

Note: Data cables should not be run across or next to power cables to avoid signal interference problems.

Screen Layout of the SceneScan Service Interface

The upper part of the SceneScan Service Interface window contains elds relating to communications, as follows:

Take Command / Relinquish Command – This button allows the user to toggle the command mode of the SSI between In Command and Monitoring.

Connect – Replaces the Take Command / Relinquish Command button when the SceneScan Service Interface is disconnected from the Sensor, allowing re-connection.

Status Display – Indicates the current status of the system, e.g. “System Running Normally” or “System Suspended”.

Activity Wheel – A green rotating animation when the SceneScan Service Interface is connected to the Sensor; ‘green and stationary when disconnected’; red and stationary when there is an error condition.

The remainder of the SceneScan Service Interface screen is occupied by one of several tab areas.

The Status Tab

The Status tab gives an overview of the operational state of the system; it contains the following elds and control buttons:

Connected State - Whether the SceneScan Service Interface is “Connected” to the Sensor or “Disconnected”.

Sensor State - “System Running Normally”, or “System Suspended” when the SSI is connected, or “System Disconnected”, “Communications Error”, or “System Disconnected (Fatal Error)” when not connected.

Sensor Address - Ethernet IP address of Sensor.

Suspend / Resume button - Can be used to suspend/resume the sensor when In Command.

Sensor Type - “SceneScan” if the SceneScan Service Interface is connected to a physical Sensor, “Emulator” if connected to the SceneScan Emulator application or “Blank” if not yet connected.

Tracking State - “Not Tracking”, “Starting Tracking” or “ Tracking”.

#Tracked Reectors - Not applicable for SceneScan

Last Time Feedback Received - In hh:mm:ss format; updated once per second regardless of command mode and blank when disconnected.

Get Service History - Enabled when tracking is not in progress. When clicked, a Browse For Folder window allows you to choose a storage location. Clicking OK then causes the service history information to be written to an .xml le in the chosen location. The le, named ServiceHistory_<Sensor serial number>.xml, can then be sent to Guidance Marine for analysis as necessary.

Vessel Parameters

The Vessel tab allows you to dene the dimensions of the vessel outline on the BEV, the name of the vessel and other items as follows:

Vessel Name: The name of your ship (displayed on the Dashboard).

•

Vessel Length: The distance from the bow to the stern of the vessel in metres.

•

Vessel Breadth: The width or beam of the vessel in metres.

•

Bow Oset: Distance from the centre of the SceneScan Sensor to the vessel’s bow, in

•

metres.

Starboard Oset: Distance from the centre of the SceneScan Sensor to the vessel’s

•

starboard side, in metres.

Bearing Oset: This should be 0° if the SceneScan Sensor is mounted exactly parallel

•

to the vessel’s centre-line running from bow to stern. If the Sensor is at an angle to the centre-line, enter a Bearing Oset to compensate for this (see Bearing Offset on page

62).

Default Vessel Orientation: The default direction of the vessel bow as displayed on

•

the Bird’s Eye View of the Dashboard. Changing this setting rotates the whole BEV but does not aect the data sent to the DP system. Note that this setting can be overridden for the current Dashboard session via Advanced > Display Options > Layout > Vessel Orientation, but the BEV reverts to the default orientation when the Dashboard is closed and re-opened.

It is very important that the vessel dimension parameters are set accurately as laser pulse data returned from within the vessel area is ignored by the positioning algorithm; it is eectively a vessel shaped blanking zone.

Modifying Vessel Calibration

In order to amend any of the above parameters:

1. Click on the Resume button if the Sensor is supended.

2. Click on the Take Command button if the SceneScan Service Interface is not already In Command.

3. Ensure that no tracking is in progress.

4. On the Vessel tab, click on the Edit button.

5. Amend the Vessel Calibration as required.

6. Click on Apply to save the changes or on Cancel to discard.

Static Blanking Zones

Static Blanking Zones are used to mask segments of the scan rotation that are obscured by the vessel’s superstructure. While the scanner passes through a blanking zone, the laser is switched o to prevent unwanted reections from interfering with the scene data.

Viewing the Static Blanking Zones

The Blanking tab of the SceneScan Service Interface displays each of the congured zones and their Start and Stop angles in degrees. In order to distinguish one zone from another, clicking on a Show Zone n button will cause the corresponding zone to be displayed in a dierent colour, along with the button itself.

Modifying the Static Blanking Zones

1. Click on the Resume button if the Sensor is suspended.

2. Ensure that no tracking is in progress.

3. Click on the Take Command button if the SceneScan Service Interface is not already In Command.

4. On the Blanking tab, click on the Edit button.

Dynamic Positioning Feed Conguration

The SceneScan system provides positional data messages to the vessel’s Dynamic Positioning (DP) system, for correct functionality, the format and behaviour of this output stream needs to meet the requirements of the DP system.

The current DP conguration settings are displayed on the DP Cong tab of the SceneScan Service Interface, along with the most recent message emitted. See DP Message Types (page 70) for details of each available message format and DP Feed Behaviour (page

66) for details about each of the function of the Keep Feed Enabled and Allow Zero Strings

parameters.

DP Feed Behaviour (Continued)

1. The DP Feed has 2 possible states: Idle and Tracking. It is in the Idle state if the system

is not tracking or if the system is tracking but the DP Feed Output is disabled. It is in the Tracking state if the system is tracking and the DP Feed Output is enabled.

The current state of the DP Feed can be seen on the DP Feed Menu on the Dashboard.

Note: The performance (quality) of the tracking does not have any impact on the DP Feed state, however, it does inuence the DP Feed strings (status ags) that are being output by the Sensor.

2. Fresh positional data refers to the current range and bearing values (obtained during last

revolution of the Sensor) that the tracking algorithm calculates.

3. Stale positional data refers to the last set of valid range and bearing values that the

tracking algorithm calculated.

4. Valid status means that the positional data in the DP Feed output string is valid. Invalid

status means that the positional data in the DP Feed output string is invalid. Depending on the selected DP Feed format, the status information (valid / invalid) can be derived from the Tracking ID (0 for invalid, 1 / 2 for valid) or from specic status bits (0 for invalid, 1 for valid).

5. Kongsberg BCD is not included in either of the two groups in the table as it has a dierent

behaviour. This DP Feed format only contains range and bearing information, it does not contain any information about whether the positional data is valid / invalid. For more information on this DP Feed format, check DP Message Types section (See page 71 - 75)
