The performance capability of many designs, especially vehicles, depends on their weight. Necessary conditions for designing a new generation of technology are increasing strength-weight ratio of structures, reducing their weight, increasing the payload by developing new approaches to design. Besides this urgent task of improving the efficiency of structures, the relevance of this study is determined by the need to find alternative options for employment of shipbuilding industries under the conditions of instability in their business portfolio. In the present study, an analysis was made of the technical and economic feasibility of mastering the production of innovative tank containers for the transport of LNG using an innovative sparingly alloyed aluminum-scandium membrane. The trend of multimodal cargo transportation with the use of tank containers, allow building the best routes, where different types of transport can be involved without additional reloading operations is very promising today. A positive conclusion was made about the introduction of this type of product into the production program of shipbuilding enterprises.
