On December 16, the world’s latest generation of "Chang Heng Series" 174,000 cubic meters of liquefied natural gas (LNG) carrier jointly developed by Hudong-Zhonghua Shipbuilding (Group) Co., Ltd., a subsidiary of China State Shipbuilding Corporation Limited and French GTT Company, was awarded a U.S. ship Ship Type Design General Approval (GDA) and Pre-Class Approval (PCA) issued by four internationally renowned classification societies (ABS), French Classification Society (BV), Lloyd's Register (LR), DNV, etc. Wait for the certificate.

This is the latest achievement and the best comment of the 20-year friendly cooperation between the two parties. It is also a major event in the history of the development of LNG ships in the world. It is also an important milestone in the process of China’s development and design of LNG ships from following up and leading the way. With the latest design concept, the best technical equipment, the strongest environmental performance, and the most forward-looking "Changheng Series" ship model finally came out, reaching a state where it can be built on a real ship, providing more for the global LNG trade. Innovative solutions for efficient and environmentally friendly LNG transportation.

  LNG ships are described as "super-refrigerated vehicles" at sea.

In order to transport more capacity of natural gas as much as possible, humans reduced its temperature to minus 163 degrees Celsius and compressed it 600 times into liquefied natural gas (LNG), making it more convenient for high-capacity, high-efficiency, and long-distance transportation. Therefore, LNG ships Came into being.

  LNG has a greater risk in the transportation process, once it leaks, it will cause an explosion.

To this end, LNG ships are internationally recognized as high-tech, high-difficulty, and high-value-added "three highs" ships. Together with luxury cruise ships and aircraft carriers, they are known as the "Crown Pearl" of the shipbuilding industry.

At present, only a few shipyards in the world have the ability to build, and Hudong Zhonghua is the only base in China that can develop, design and build such high-end products.
