A SIMPLIFIED CALCULATION OF THE INTERACTION FORCES BETWEEN HULL AND TANK SYSTEM FOR A MOSS ROSENBERG TYPE LNG CARRIER

The interaction between hull and cargo tank system in a LNG carrier with spherical tanks of Moss Rosenberg design has been investigated by means of a three dimensional frame model, where also membrane elements are included. The method of analysis presented is shown to give a reasonable accuracy compared to results from a complete three dimensional finite element analysis and measured values. Such an analysis can be carried out in a fraction of the time taken by other methods and should therefore be of interest at the initial design stage, and also when effects of modifications are to be evaluated.
