For the preliminary design stage, the evaluation of vertical strength is mandatory for the preliminary scantling of the structure. This paper presents the evaluation of the vertical sectional efforts by equivalent beam approach, using the 3D-CAD lines plan of a 3000 tdw barge and mass diagram. For numerical analysis the own program P_QSW is used, for sagging and hogging wave condition, ship headings 0 and 45o, wave height max. 1.2 m. The vertical sectional efforts are compared with the maximum bending moment and shearing force prescribed by the classification societies for the 3000 tdw preliminary vertical strength assessment.
