Thrusters
NOTE! Some configurations provides no heading priority in the AutoHdg-
ManPos modes
6.1.2.3 Thrust Ability Diagram. Automatic Modes
When the position is controlled automatically, the Thrust Ability Diagram continuously informs the of the margin in
F and M .
If the vessel’s heading or/and position is being controlled automatically, the corresponding symbols do not match
to actual values of F and M . However, the actual values are always displayed, so the operator has information if the
achievable thrust is close to the limit.
The wind force is also displayed in the diagram as a blue vector.
Then the operator has information whether the thrusters could provide enough thrust to compensate the wind.
6.1.2.4 Thrust Allocation Status
The TAL status round Indicator placed above the bar diagram is color-coded:
Green color
indicates the thrust allocation is in operation;
Red color
indicates that either Control Forces or Control Moment is missing.
The color of X/Y/M symbols is black if the thrust allocation of this axis is in operation. The red color means that the
thrust allocation of the corresponding axis is missing.
6.1.2.5 Thrust Ability Diagram. Digital Indicators
There are digital indicators and legend at the right side of thrust ability diagram.
Control force F
control
and moment M
control
.
The green vector and bar mean the actual force and moment respectively.
Digital indicators show the components of X,Y and M in % to required force maximal values and force values in
tons.
Actual force F
actual
and moment M
actual
.
The yellow vector and bar mean the actual force and moment respectively.
Digital indicators show the components of X,Y and M in % to required force maximal values and force values in
tons.
Estimation of an actual forces is calculated using thruster feedbacks.
Signs rule is according with the Figure 2.33.
OPP DSTB force F
disturb
and moment F
disturb
.
The blue vector means the force, which is required to compensate disturbance force, while the blue bar means the
moment, required to compensate disturbance moment.
Joystick Digital indicators show the joystick and knob position in %
In
Speed VECTOR
mode the required speed is shown (see figure 6.3).
NOTE! In the “Speed VECTOR” mode (see Section 9.3.5, page 168), the X and
Y values are the required Vx and Vy (in percents to maximum value),
and the marker corresponds to the joystick position too.
At changing-over from one mode to another one position of joystick and/or knob symbol can differ from the actual
values of force and/or moment.
There is the Correction of the Joystck/Knob position Diagram at the left of the Thrust Ability Diagram (see figure
6.4). The diagram’s arrows are coded for direction and color.
