Significant progress in the construction technology of large LNG carriers in China

Recently, Huzhou Zhonghua Shipyard of China National Shipbuilding Corporation successfully completed the submersible insulation test of the 147,000 M3 liquefied natural gas (LNG) ship cargo tanks under construction, and passed the American ABS Classification Society, France GTT Company and the ship. East's joint acceptance acceptance. In order to ensure the safety of the liquefied natural gas at a very low temperature (163 degrees Celsius), the film type LNG ship must be equipped with a high precision and high reliability liquefaction enclosing system, which is the main feature and the biggest difficulty of the LNG ship. The insulation box tightness test is the complete check of the manufacturing and assembly quality of the liquefaction enclosure system. It is the most critical link in the construction of the LNG ship. Its hungry completion marks a major breakthrough in the construction technology of China's LNG ship.
