44 | Operation
In simulation mode the PMS is also simulated. In simulation mode the operator can open and close breakers for
generators and bus ties and select/deselect thrusters. In doing this the operator can study what the consequences are
for a given failure or setting without effecting (or starting) the actual system.
2.3.4 Capability
In the capability screen the operator can view the ability of the vessel to keep position and heading at a given wind speed
and direction. This can be used for consequence analysis to determine the vessels' ability to keep position under given
environmental conditions.
Figure 35: Capability Screen
Explanation Capability Section:
•
Red X/Y plot of wind capability with selected thrusters at 100%.
•
Green X/Y plot of wind capability with selected thrusters at 80%.
•
Amber X/Y plot of wind capability with selected thrusters at 80% on worst case failure.
•
Wind vector showing direction and speed. If this vector reaches the capability boundaries the vessel is out of
capability.
•
Current values and compensation settings.
•
Wind values and compensation settings.
•
Heading and ship speed.
The operator can deselect thrusters by clicking in the check box of each thruster. See Figure 35: Capability Screen on
page 44. By doing this the system will calculate the capability without this thruster. This is shown in the green plot.
Note that this is only a calculation, the thruster is not disengaged! If the system has PMS controls, the same can be done
for generators to study the effect of losing a generator on the capability.
