CSD Generic - Result Data Items

Selecting Result Data Items

Select items from:

Computations

Obviously not all these apply to dredging operations. The following are not considered here: Anchors, Catenary, Bargetrack, Eventing, Miscellaneous.

Deskewing means calculating a 'new' position (using SOG and COG) for the time of trigger. This trigger can be On Time, On Fix, On Node Result update or On System update.

Computations

These are the sub-items associated with a Computation. The need to select any one of them is remote in dredging.

The first entry is always [Priority List]. This means that the computation with the highest priority, as defined in the Controller's Computation Setup, will be used.
The rest of the list will show all available computations, as defined in the Controller's Computation Setup of the current selected QINSy database

Refer to Computations for further information.

Nodes

The first entry is always [Steered Node]. It can be changed if the position of the steered node is not required.
In our example the Spud CoG is the steered node.

Click on Result Data and then Nodes.

Click on

.

Select the node and the computation from which sub-items are drawn.

Select sub-items; in this case Name, Easting and Northing for each node selected.

These are all the sub-items available:

Modify sub-item Properties if necessary. Refer to Various for explanations of the various properties.

Refer to Nodes for further information.

The actual mainline/additional mainline selection (POINT, LINE, ROUTE) is done in the Controller's Session Setup.

Click on Line Offsets.

Click on

.

Mainline is the default line. Select the Node to be reference to the mainline.

Select sub-items Distance Across, Distance Along, MP (meter point), and Speed Across.

These are the available sub-items:

Height Aiding

Click on Height Aiding.

Click on

.

Select the Vessel. The first entry is always [Reference Vessel]. This means that the first defined object will be used (with Object Id 1).

In Database Setup you will see 'square' icon in front of the vessel name.
The rest of the list will show all available objects existing in the current selected QINSy database.

Select sub-items to display. In our example these are:

Draft - The instantaneous actual water level above Vertical Datum.
Mean Actual Water Level - The Actual Water Level minus the heave of the object, so i.e. the actual water level without the swell influence.

These are the available sub-items:

Modify sub-item Properties if necessary. Refer to Various for explanations of the various properties.

Refer to Height Aiding for more information.

Tide Results

The first entry is always [Reference Vessel]. This means that the first defined object will be used (with Object Id 1).
In Db Setup you will see 'square' icon in front of the vessel name
The rest of the list will show all available objects, existing in the current selected QINSy database.

These are the sub-items:

Tide: This is the tide component of the Height Aided Observation, on Survey Datum. This observation is calculated by the Height Aiding driver (which is always present in the Windows taskbar).
Notice that this item is the same as item Tide under Height Aiding.

Refer to Tide Stategies for more information.

Dredging Results

Lists all available dredging systems that exist in the currently selected QINSy database.

Click on Dredging.

Click on

.

Select the Dredge System and the dredge head.

Most sub-items below are 'connected' to a particular head, but some are head independent, i.e. it does not matter whether Head 1 or 2 is selected.
The presence of Head 2 depends on the type of dredger (backhoe, cutter, hopper, etc.), as defined in the Database Setup.

Select sub-items to display.

Notes on sub-items:

System Name

The name of the selected Dredging System, as defined in the Database Setup program.

Object Name

The name of the object on which the selected head is located, as defined in the Database Setup program.

Design State

Above: Head footprint is above design (including tolerance)
On Target: Head is on design level (within tolerance levels)
Over Dredge: Head is below design level (including tolerance). Usually bad news for contractor...
Not Used: Unknown/not used possible when grid data is not available

Intrusion Alarm

(Used to be known as Emergency Hoist Alarm in previous versions)

Value depends on the Horizontal Clearance Error, which is set in the Controller Session Setup, Dredging, Intrusion Detection page.

0 = No emergency. Dredge head is still far enough from the selected intrusion zone.
1 = Emergency hoist, head must be lifted immediately.

Same alarm as seen in Alert Display, Category "Dredging Result", Type: "Intrusion Detection: Error (Emergency Hoist)"

Collision Alarm

Value depends on the Horizontal Clearance Warning, which is set in the Controller Session Setup, Dredging, Intrusion Detection page

0 = No emergency. Dredge head is still far enough from the selected intrusion zone
1 = Warning, head enters the first zone.

Same alarm as seen in Alert Display, Category "Dredging Result", Type: "Intrusion Detection: Warning"

Clearance Status

A combination of Intrusion and Collision Alarms

Value depends on the Horizontal Clearance Warning, Horizontal Clearance Error and/or Vertical Clearance, all set in the Controller Session Setup, Dredging, Intrusion Detection page.

Clearance Status	Alarm	Height Mode
0	ALL OKAY	2D - XY Position
1	WARNING	2D - XY Position
3	HOIST	2D - XY Position
0	ALL OKAY	3D - XYZ Position
5	WARNING	3D - XYZ Position
7	HOIST	3D - XYZ Position

Deepest Easting/Northing/Height

Coordinates of the deepest point of the dredge head.

Cutting Easting/Northing/Height

Coordinates of the cutting point of the dredge head.

Height Above Design

Actual height minus the design height at footprint of the selected head.
Positive value means the head is above level.
Negative value means head is below level.

Design can be manual or from a sounding grid.

Anchors

Click on Anchors.

Click on

.

Select the Anchor. The first default entry is always [All Anchors]. Accepting the default means that selected sub-items are common to all anchors.

Individual anchors as defined in the Controller's Session Anchor Setup of the currently selected QINSy database are shown in the drop down list.

Select sub-items to display.

Notes on sub-items:

Id	Id of defined anchor, as given by the Controller's Session Anchor Setup. The first defined anchor will have id 1, the second 2, and so on. Notice that if you add a new one, it will always have the id of the last one plus one.
Status	Current status of the defined anchor. The following labels are possible: "Not Assigned" "Racked" "Transit" "Dropped"
Easting Northing Latitude Longitude	What these values are depends on the current state of the anchor: Free Anchor, Not assigned Co-ordinates of the planned location apply. Racked Anchor, No Tug assigned Co-ordinates of the rig winch node apply. Racked Anchor, Tug Assigned Co-ordinates of the rig winch node apply. Anchor in Transit, Tug assigned, Multi Vessel Operation Co-ordinates of the tug roller node apply. Anchor in Transit, Single Vessel Operation Co-ordinates of the rig winch node apply. Dropped Anchor, Tug assigned Co-ordinates of the dropped location apply. Dropped Anchor, No Tug assigned Co-ordinates of the dropped location apply. Grid co-ordinates are always on survey datum. Geographical co-ordinates can be on survey datum or on WGS84.
KP	Notice the additional Nr Format Property: "Station+Offset (US notation)". This formats a KP value as a Station+Offset (USA notation), where Station is the KP value in survey units / 100 and the Offset is the remainder (in survey units). For example: MP 2345.6 feet along a route becomes 23+46. KP 1.234 (equals MP 1234.0) becomes 12+34. The plus sign will be a negative sign when the KP is negative.

Refer to Anchors for further information.
