| Abstract: | The three-dimensional fully coupled global strength analysis of a large topside transportation vessel is carrier out by using design wave method based on frequency domain analysis .Interaction between the topside and barge is accounted for by including for the flexibility of barge in the structural analysis .The global structural model and the hydrodynamic model are estab-lished, multiple software programs of SESAM package are used to ensure the accuracy of motion analysis and structure calculation. |
