Draft Survey: Barge Overhang Method
I found this alternative method from draft survey course book, hope it usable. Frankly, I never use this method yet, as we required the barge owners to provide the hydrostatic table for draft survey.
The overhang method use the same principles with the method of calculating the volume of a prism. The weight of the barge will be getting by multiplying the volume with the water density where the barge is afloat. Measure the dimension of the barge, before and after the loading/discharging is required for the length and width of the barge, barge freeboard, overhang aft and fore.
The method is applied when :
– The barge is of cut-up type.
– There is no table or data.
– The concerned parties agree on the use of overhang method for weight determination of barges.
