Draft Survey for Large Ships

Satisfaction Guaranteed:
Aboard tankers , it is a frequent practice of Ships Officers to take draft surveys many times a day. Since you are loading at a fast rate which sometimes exceeds 250Tons/Hrs , Draft changes considerably at every end of watch, And it is not possible to record all the six draft marks at all times. Sometimes we have to be contented with just the drafts on the port side or the Starboard side.

Avocet has designed this App with the above in mind. If you take the draft on one side then you can fairly estimate the draft on the other by matching the List angle with the Inclinometer.

Avocet Draft Calculation is a mobile load and stability indicating App which has
User Friendly Graphic .
Various Report presentation Draft , Cargo and Calculation Results.
Inbuilt Help.
Create and store conditions
Tank filling using global tools.
Visual Display of Trim and Heel as you type in the Draft.
Easy exchange of Data .
Emailing of Data report.
Draft Trim CARGO etc computation on the fly in real time.
Displacement and weight Calculations
and many more
The optimum condition would be to take all the six draft , get the dock density , determining the deductibles and then using hydrostatic table to get the weight of the cargo loaded.

Import of Hydrostatic Tables and Tank Plan has been made much easier . You just create a CSV file in the style explained using Excel or Notepad on Mac or Windows and import it directly. No internet connection is required.
Or you can send the hydrostatic tables and Tank Plan in any form to workshop@avocetdata.com and we shall create the file and send it to you.
