On the hull models accuracy for barge type B1740T Europe B2 used for the processing of the draught survey records

Abstract

For the river shipping the transported cargo values have to be computed based on the DS-draught survey records. Differences for cargo masses are recorded between DS and the on-shore weight. In order to increase the accuracy of the DS - draught survey procedure, we have developed the DRSWIN program based on a digital barge shape model. The quality of the barge shape model has a significant influence on the overall draught processing accuracy. For the barge type B1740T Europe B2, we have developed three hull shapes digital models with different density of the offset-lines. The results point out the most suitable hull shape digital model for the best accuracy on DS - draught survey processing.
