NAVIS NavDP 4000. Operation Manual

Capability Analysis
Capability Analysis is performed to investigate the limiting environmental disturbances (waves, wind and current)
under which the vessel position and heading can be maintained. The analysis can be performed for set thruster and power
configurations and environmental conditions.
The results of Capability Analysis are presented on the Capability Plot.
Two modes are provided for the Capability Plot:
Real Mode
and
Hypothetic Mode
.
Real mode
— the vessel’s capability to maintain its position and heading is evaluated with regards to both present con-
ditions of thrusters and power components and environmental disturbances (waves, wind and current);
Hypothetic mode
— the vessel’s capability is evaluated with regards to both simulated failures and limitations of
thrusters and power components and combinations of waves, wind and current.
Use the Capability Plot to determine operational limits and the optimal vessel heading for safe operations.
Capability Plot
A Capability Plot (see Figure 10.57) is displayed in the CAP Analysis window. Press
Select window
on
SYS
panel
and select
Cap Analysis
item for displaying.

Capability Plot Softkeys
TRUE/REL
— CAP Plot view.
The Capability Plot is displayed in two views (see Figure 10.58):
TRUE
— orientation to the North;
REL
— orientation to the vessel’s heading.
Press
TRUE/REL
softkey to switch the present view.
The view selected by the operator persists after
NAVIS NavDP 4000
restarting.
