Dynamic Positioning Data - Speed Effects on Steerable Thrusters Tab

The effect of forward speed can reduce the effectiveness of thrusters. The percentage of thrust for tunnel thrusters due to the forward speed of the vessel can be set using this dialog.

You may add and delete speeds as required by using the Add Speed and Delete Speed buttons respectively. Speeds may be deleted by highlighting one or a number of rows. The Delete Speed button will then be activated so that you can delete the data.

Note:
A maximum of 20 speeds (Froude numbers) can be set using this dialog.

The thrust loss is also dependent on the inflow angle to the thruster.

The User may add and delete angles as required by using the Add Angle and Delete Angle buttons respectively. Angles may be deleted by highlighting one or a number of columns. The Delete Angle button will then be activated so that you can delete the data.

Note:
A maximum of 10 inflow angles can be set using this dialog.

Percentage values should be entered in the appropriate cells. Obviously, only percentage values between 0 and 100 are accepted.
