NAVIS NavDP 4000. Operation Manual
Figure 9.9: Manual Surge
NOTE! This mode is mostly intended for automatic maintaining the vessel on
a straight path, while the vessel’s motion in the surge direction is con-
trolled manually. Therefore, you are recommended to use Auto heading
control only.
This mode might be useful if the vessel is required to operate along a straight line, in the presence of wind, waves and
current. First bring the vessel more or less close to an imaginary line along which the vessel is to be moved.
Press the AUTO softkey in the HDG panel and set the heading setpoint, so that the vessel is directed along the
imaginary line. Then press the man SURGE softkey. After that a bar appears on the screen, where you must enter the
position setpoint. If the current vessel’s position is exactly on the path, you can just press the HOLD softkey and then
OK , otherwise set a new position setpoint. In both the cases you will set the position setpoint, while the heading setpoint
have been set earlier. These two values (the heading and position setpoints) define a straight line, along which the vessel
will be moved. The controller calculates the lateral deviation from the line and tries to drive this deviation to zero; while
the longitudinal vessel’s motion is controlled by the joystick (the lateral joystick axis is disabled).
During the operation, you can change the position setpoint, which means that the required path shifts in parallel.
In this control mode, the X-part of demand force vector is calculated by the controller, and the joystick is disabled.
Following options can be used in this mode:
Position Setpoint Set Position Offset the position
Remote COR position COR in bow, stern, or other specified point
Following parameters are available from Operator Station:
Fore-aft speed
Maximal allowed vessel speed in the surge direction
Position Gain Gain of Position Controller
Position Limit Limit for alarm
Joystick Gain
Settings (Low, High, Progressive)
9.3.4 Manual Sway
Similar to the Manual Surge mode.
Use the
man SWAY
softkey.
In this control mode, the Y-part of demand force vector is calculated by the controller, and the joystick is disabled.
The vessel lateral motion is controlled by the joystick (the longitudunal joystick axis is disabled).
The vessel motion in Manual Sway mode is shown in Figure 9.10.
Following options can be used in this mode:
Position Setpoint Set Position Offset the position
Remote COR position COR in bow, stern, or other specified point
Following parameters are available from Operator Station:
