The object of research is the design features of tanks for gas transportation in a compressed state and the criteria for their comparative evaluation. One of the most problematic places is the lack of a unified approach to the non-economic evaluation of the efficiency of transportation of compressed gas in high-pressure tanks. The issue is of particular importance in the conditions of gas transportation by sea and, in particular, produced on the shelf. This is due to the diversity of tank designs offered by manufacturers, characterized by different working pressures and design. To create the possibility of evaluation of the mass-dimensional perfection of high-pressure tanks, an analysis of the structures suitable for the formation of the cargo systems of marine vehicles, and the criteria for their comparative evaluation has been carried out. Also the design of multi-cavity high-pressure tanks of increased working tank is proposed. They consist of steel and fiberglass pipes and special connections with plug-in retaining elements. Considering that it is common to use normal cubic meters for gas metering, a new universal criterion is proposed for comparative evaluation of their perfection. It is determined by the ratio of the mass of the tank to the volume of gas transported in it to normal conditions. The criterion establishes the relationship between the amount of gas transported and the main parameter of the tanks, taking into account their inclusion in the freight systems of vehicles. According to the specified criterion, multi-cavity tanks are competitive in terms of their performance in the form of a lengthy design, limited by the parameters of the marine vehicle. Due to the universality of the proposed criterion, it is possible for manufacturers of high pressure vessels to use them in promoting products in various industries. For the perception of the new criterion by consumers, it is necessary to conduct its comparative analysis with the criteria used today for evaluation of perfection for tanks of various types and parameters.
