Capability Plot Legend
White-colored vessel contour
is displayed in the centre of the plot. It is directed to the present heading.
Wind speed dial
is displayed as
white
circles for 10, 20, 30, 40 and 50 m/s (the units are set and may be changed
in “Units” Page of “Param” window — see Section 5.9, page 85). The circle for 50 m/s is overlapped with the
directional dial.
Present wind speed
is displayed as
yellow
circle. It allows the operator to evaluate the vessel’s capability to maintain
position at the present wind speed.
Green marker
indicates current direction.
Yellow marker
indicates wind direction.
Cyan marker
indicates wave direction. It matches the wind direction in Auto mode.
Electronic Bearing Line (EBL)
EBL (Electronic Bearing Line)
is displayed as
lilac
line. It is directed to the North by default.
EBL is intended for selecting direction for which the limiting wind speed at which the vessel is able to maintain its
position and heading to be determined.
– Assume, the operator needs to know the limits for the vessel heading 0
∘
. For this purpose EBL value should be set
as 0
∘
. The limiting wind speed is about 14.1 m/s (see Figure 10.59).
– For the heading 30
∘
the limiting wind speed is about 18.0 m/s.
The calculated limiting wind speed values both for the present heading and for the EBL direction are displayed under the
Capability Plot.
Press
Change
softkey near the
EBL
text to set a new EBL direction.
In the opened dialog box enter a new value for the EBL direction and press
OK
(see Figure 10.60).
The following areas depending on both wind and wave disturbances and current speed are presented in the Plot:
