• The deviation between the estimated heading and the heading setpoint is shown
in the Heading area of the display (see Automatic heading control on page 24).
• When the vessel speed (in both the surge and sway axes) is reduced to less than
predefined limits, automatic position control is enabled and the Auto surge
and
Auto sway
button status indicators become steadily lit. The current vessel
position becomes the position setpoint, and the system automatically keeps the
vessel at this position.
• The deviation between the estimated position and the position setpoint is shown
on the Position area on the display (see Station Keeping mode on page 26).
Autopilot mode
The optional Autopilot mode enables the vessel to accurately and automatically maintain
a selected heading. This mode uses the vessel's propeller(s) and rudder(s) or azimuth
thrusters.
The vessel speed is normally controlled from the joystick on the operator terminal.
If the vessel's rotation centre is other than the centre of the vessel (midships) when
entering the optional
Autopilot mode, it is automatically changed to the centre of the
vessel and the status indicator above the
Centre pivot
button is steadily lit.
At least two gyrocompasses must be enabled. If this requirement is not met, the message
Heading monitor requires 2nd source
is displayed.
At least one speed sensor must be enabled. If this requirement is not met, the message
Speed sensor dropout
is displayed.
Entering the Autopilot mode
To enter the optional Autopilot mode, proceed as follows:
1
While still in Joystick or the optional Station Keeping mode, manoeuvre the vessel
onto the required heading.
2
Ensure that the required main propulsion units and rudders are enabled (see
Enabling thrusters on page 95).
3
Ensure that two gyrocompasses are enabled (see Enabling a gyrocompass on
page 98).
4
Ensure that the speed sensor enabled (see Enabling a speed sensor on page 103).
5
Select the required autopilot gain level (see Selecting the autopilot gain level on
page 117).
6
Set the required counter rudder gain (see Setting the counter rudder gain on
page 117).
7
Set the required auto trim gain (see Setting the auto trim gain on page 118).
8 If required, enable weather compensation (see Enabling weather compensation
on page 119).
