NAVIS NavDP 4000. Operation Manual
The consequence indicator (5):
light grey — all components included in the analysis are not active (there are no red or green indicators and at least one
indicator is light-grey);
dark grey — there is no failure included in the analysis (all indicators are dark-grey);
green — at least one active component is included in the analysis (at least one indicator is green and there are no red
indicators);
red — there is at least one critical failure of component, included in the analysis (at least one indicator is red).
The indicator of the component state in the Consequence analysis (6):
light grey — the failure is included in the analysis but the component is not active;
dark grey — the failure is excluded from the analysis;
green — the failure is included in the analysis and the component is active;
red — a critical failure of the component (the failure is included in the analysis). The critical failure is the failure after
which the thrusters are not able to produce sufficient thrust and/or power components — sufficient amount of power
for the vessel’s capability to maintain its position.
The alarm message is generated in this case.
Softkeys
9 and 10 softkeys are used to go through the list.
On/Off (11) softkey is for the including to the analysis and excluding from the analysis the selected failure.
CAP Plot (12) softkey
opens the Capability plot window and activates the capability analysis function in the Hypothetic
mode.
Drift Plot (13) softkey opens the Drift plot window and activates the drift analysis function.
The table on Figure 10.89 contains the current and average values of the thruster forces.
Figure 10.89: The forces indicator
The table on Figure 10.90 contains available and used power values on the buses.
Figure 10.90: The power indicator
In case of two or more buses are off, they considered as separate ones, as well as the used power value is displayed.
10.11 CPU Temperature Monitoring
NAVIS NavDP 4000 provides two-level temperature monitoring:
Two sensors are installed in the system:
– CPU temperature sensor;
– System temperature sensor.
To view the present CPU and System temperatures select Services item

Info on the Starter screen (see Figure
10.91).
For each sensor the alarms of two categories are generated:
