Parent Item

System

List with all available dredging systems that exist in the current selected Qinsy database.
(see General Layout Information about loading a Qinsy database).

Head:

Most items below are 'connected' to a particular head, but some are head independent.
For those items it doesn't matter whether Head 1 or 2 is selected.

Head 1
Head 2
The presence of Head 2 depends on the type of dredger (backhoe, cutter, hopper, etc.), as defined in the Database Setup.

Intrusion Alarm

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

Value depends on the Horizontal Clearance Error, which can be 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)"

int

Collision Alarm

Value depends on the Horizontal Clearance Warning, which can be 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"

int

Clearance Status

(A combination of the Intrusion and Collision Alarm)

Value depends on the Horizontal Clearance Warning, Horizontal Clearance Error and/or Vertical Clearance, which can be 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

double

Heading

Grid heading of the selected head object

double

Center Easting

Center Northing

Center Height

Grid co-ordinate of the center of the selected dredge head.

double

Deepest Easting

Deepest Northing

Deepest Height

Grid co-ordinate of the deepest point of the selected dredge head.

double

Cutting Easting

Cutting Northing

Cutting Height

Grid co-ordinate of the cutting point of the selected dredge head or the point that is closest to the design.

double

Height Above Design

Actual height minus the design height at footprint for deepest point 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.

double

Design Height

Height of design at footprint for deepest point the selected head.

Design can be manual or from a sounding grid.

double

Dredged Layer Thickness

Amount of removed soil.

Value is calculated for the deepest point of the selected dredge head.

Will be zero when the selected head is above the selected bathy layer.

double
