Strength calculation and stress analysis were conducted for the connecting structure between inner vessel and outer jacket of a multimodal transport LNG tank.According to the calculation results, the structures with high stress,namely the supporting seat at the fixed end of the inner vessel and the supporting cover at the slideable end of the outer jacket lower part,were optimized.The stress of the im-proved structures of the LNG tank were greatly reduced,which can meet the design requirements and norms.
