10.14 DP Footprint Plot (Option)

DP Footprint function is intended to estimate vessel's position keeping quality in real time conditions: with actual
configuration/status of thruster/power components and present environmental disturbances (waves, wind and current).
The vessel's deviations from position setpoint are graphically displayed on DP Footprint Plot.
In case DP Footprint function is available, additional "Foot Print" softkey will be displayed below the map in "Map"
window (see Figure 10.102).
To conduct DP Footprint plot:
1. Choose auto control modes:
– AUTO Position;
– AUTO Heading.
WARNING!
2. Set the following DP Footprint parameters in "System" page of "PARAM" window.
Observation number (10, 15, 20) — number of points marked as X on the plot and displaying the vessel devia-
tions;
Plotting interval (30 s, 1 min, 2 min, 5 min) — a period of time for plotting a regular mark of the vessel position.
3. Press "Foot Print" softkey to get DP Footprint Plot printout.
The Plot is printed out on the Network printer configured in NAVIS NavDP 4000 system for printing information
(usually Screen printer).

For conducting DP Footprint plot it is recommended to select a
safe location away from structures, other vessels, etc.
"Foot Print" softkey becomes available after all position marks corre-
sponding to the selected Observation number are plotted. The process
may take up to 100 minutes.
