What standards determine the size design of LNG tankers?
Thread Content
I checked some information; it seems to follow the regulations for mobile pressure vessels, but I couldn’t find any specification regarding the maximum volume. The common volumes on roads are 52.6 cubic meters and 55.6 cubic meters – what is the maximum allowed volume according to our regulations? I’ve seen ones abroad that are 90 cubic meters. Are there any regulations regarding tank trucks regarding the requirement for built-in liquid pumping systems and pressure vaporizers? It seems that vehicles produced in recent years don’t come equipped with these, but older vehicles did
According to the standard \"Classification, Dimensions and Rated Mass of Containers\" (GB/T 1413-2008), the external dimensions of a 40-foot container are 12192 mm (length) × 2438 mm (width) × 2896 mm (height), with a rated total mass of 30,480 Kg. Based on this data, LNG tank containers with a volume in the range of 20 m3 to 35 m3 can be designed for transportation by vehicle and ship. Currently, Staden has launched on the market 20m3 LNG tank containers, 27m3 LNG tank containers, 27m3 LNG tank containers, 35m3 LNG tank containers, and 52.6m3 LNG tank containers; these products require high-performance liquid filling pumps and pressure-boosting vaporizers.

Currently, the maximum capacity of domestic LNG tankers is 52.6 cubic meters, as specified by Amendment 1 to the \"Mobile Storage Regulations\". Later on, the volume of liquefied gas tankers will also need to be restricted; it’s not the total weight or size that matters. It’s due to fierce competition in China, where there is a constant pursuit of larger and lighter vehicles, and any technology is willing to be used, which poses significant risks. **Therefore, regulations are needed to limit the volume and establish uniform standards. There are no international standard limits for this; it is a characteristic of China’s specific national conditions.
Since a modification permit is required to operate tank trucks, our company can no longer do business. I didn’t pay attention to the moving tolerance. Yes, it is specified in 52.6, but the total weight still needs to be controlled.
