Anchoring Status
The Status tab enables you to monitor the
anchor drag after the ship is anchored. All
values in the Status tab are read-only,
generated from values entered at Planning.
Anchor Watch Mode
Click the Drop Anchor button to switch to
Anchor Watch mode, the anchor drop display is
drawn, set to ownship hawsepipe position. The
Anchoring Feature On check box in the
Anchorage area is automatically switched on
when Drop Anchor is activated.
During the Anchor Watch mode, the application
periodically monitors the ship's position to see if
the anchor is being dragged. An Outside
Anchor Watch Area alert is generated if
movement is detected in relation to the Anchor
Point.
A line is drawn from the hawsepipe to the
anchor location. This line is initially at zero
length and represents any movement own ship
makes from anchor position, based on wind,
tide or current (see the figure below). Any
movement is monitored on the Anchorage area
of the Status folder.
Suitable warnings are generated when own ship passes over the drag ring
(inner ring) and beyond the swing ring (outer ring). The warnings are
escalated to alarms when own ship sails beyond the drag and swing rings.
If the Anchoring Feature On check box is switched off, the Status tab
continues to show data based on the last placed anchorage position.
