Opis:: A design of the hotel barge of 52 m overall length and 9 m breadth , intended for inland waterway shipping on the route from Berlin to Kaliningrad, is presented. Hull of the barge is characterized by a unique structure consisted of densely stiffened aluminium panels of 4.5 mm plate thickness and 70 mm depth of stiffeners, supported by transverse walls or girders. The stiffeners of the panels are longitudinally directed. Also, are described problems associated with assurance of adequate strength and stiffness of such structure, resulting from a limited maximum depth of the barge.

dynamic stresses in ship hull structures
Opis:: The paper presents a discussion on the strength criteria and load cases required in the rules of classification societies for direct FEM strength analysis of ship hull structures, which show some differences to each other. The conclusion of it is that detail studies on stress values in ship structures are necessary to improve the requirements. With this end in view an effective method for long-term prediction of stresses in ship hull structure princiŹpal members is proposed. The method is based on the concept of influence coefficients and spectral analysis of wave loads. A FEM model of the principal member system in the form of 3D frame is applied to calculate values of the influence coefficients. Next, the concept is used of correlaŹtion factors for combining characteristic long-term stress values caused by global and local loads, with combined stresses due to general bending of the ship, zone bending of the principal members and local bending of longitudinals. As an example, results of stress prediction and correlation factors calculated in some points of hull structure of a panamax bulk carrier are presented and discussed.
