All of the thruster units should be set up using this tab sheet. You may Add and Delete units as required. Thrusters may be deleted by highlighting one or a number of rows. The Delete button will then be activated so that you can delete the conditions.
Note:
As thrusters are added and/or deleted, the number of thruster units is displayed.
NF = Number of Fixed Thrusters
NR = Number of Longitudinal Thrusters with rudders
NS = Number of steerable thrusters
Then the number of thruster units = NF + 2*NR + 2*NS.
The number of thruster units must be between 3 and 15 to allow calculations to be performed.

Type |
One of four available thruster types:
|
|
X |
The longitudinal position of the thruster (from midships). |
|
Y |
The transverse position of the thruster (from the center-line). |
|
Azimuth Boundary |
Only required for Steerable thrusters. The barred zone is defined clockwise in terms of the prohibited thruster wash of a particular unit. Care must be taken in defining barred zones for angles which are either negative or greater than 180 degrees. Hence (-135 -45) defines a barred zone between -45 and -135 degrees, whereas (-45 -135) would be incorrect and would define a barred zone between (-45, 0, 180, -135). |
|
Thrust |
The maximum thrust of the unit. For steerable thrusters, only a single (Positive) value is required. For other thrusters, both Positive and Negative values are required. Note: |
The Thruster-Power relationship and speed effects on thrusters may be set by clicking on the Advanced button.
