On the software DRSWIN designed for barges draught survey processing

Résumé

During the exploitation of a barge, the displacement is computed in order to establish the transported cargo mass. In this paper the DRSURVEY, DRCD, DRSWIN eigen softwares are presented, being an integrated system for displacement computation by DS - draught survey records. The accuracy of the DS - draught survey procedure is enhanced by taking into account the ship's girder real deflection and trim, based on a digital model for the barge lines. For several DS - draught surveys records, the displacements are computed and the eigen codes are validated.
