This section of the vessel file defines long-period changes in the vessel's draft due to fuel burn or other loading changes.
Specifically, it defines the height of the waterline below the Reference Point.
If the Waterline Height is not defined here, HIPS uses a default of zero as the height.
If you want waterline height to be applied during sound velocity correction, there must be a value in the Waterline Height section of the HVF.
No interpolation of waterline height is done during sound velocity correction. |
1. Click Waterline Height in the Sensors list box to highlight the selection and display the waterline data fields.
2. Type data (as needed) in the following fields:
Date: The year and Julian day of the current waterline time stamp.
Time: The hour and minute of the current waterline time stamp.
Waterline: The distance from the RP, positive when below the RP.
Apply: Select Yes to apply the waterline data in the Merge process.
Comments: A text field for your use.
For Kongsberg data, the Waterline value must be set to the same value recorded as WLZ in the Kongsberg Installation Datagram. This Waterline value will only be used during Sound Velocity Correction. Set the Apply switch to “No”. If it is set to “Yes”, it will be applied twice, once in SVC and again in Merge. |
