What is a LNG carrier? LNG is the English abbreviation of Liquefied Natural Gas. Literfied Natural Gas translates literally to LNG, which means LNG carriers are LNG carriers. In advocating environmental protection, liquefied natural gas as a new energy source is becoming more and more popular. This is followed by an increase in the volume of transportation, and LNG carriers have become more and more marketable. How much do you know about LNG transporter related knowledge? Here we come together to popularize it.

LNG carrier type

As the most important tool for LNG land transport, LNG transport vehicles are highly flexible and economical. For the classification of LNG carriers, there are currently two main forms in China: LNG semi-trailer tankers and LNG container tankers. The transport carrier of the LNG semitrailer transport tanker is a liquefied natural gas tanker; the transport carrier of the LNG container tanker is a tank container.

Analysis of LNG Transporter Structure

The main structures of the LNG semi-trailer tanker and the LNG container tanker are basically the same, with the difference that the former is the tractor and the latter is the chassis. Among them, tank containers are mainly used for multimodal transport, which facilitates tank loading and unloading. The tank body is a high-vacuum, multi-layered, adiabatic storage tank whose thermal insulation properties directly determine the pressure inside the tank. If the thermal insulation performance is not good, the pressure in the tank will be unstable, which will seriously affect the safety of transportation.

LNG transporter loading and unloading principle

When LNG carriers are equipped with liquefied natural gas, they need to go to specialized LNG stations for loading. Gas stations use pumps for filling. Normally, they are loaded directly into professional LNG stations, and they do not have to do it themselves. The unloading truck is an LNG transporter that pressurizes the transport vehicle through a supercharger, so that the LNG passes from the transport vehicle's discharge pipe to the outside storage tank.

LNG Transporter Notes

The understanding of liquefied natural gas tankers revealed that the main safety hazard lies in the large number of valves and joints in the rear operation box, such as safety valves, liquid phase valves, and vent valves. These valves are directly connected to the tank. Problems may cause leakage of LNG. Therefore, the above locations must be inspected frequently. If asked, they can be dealt with promptly to avoid accidents.

The above is about the LNG transporter's knowledge, not necessarily comprehensive, but practical. In the future, this type of vehicle may grow more and more. When you hope to meet LNG transporter again, you will no longer be at a loss.
