Recently, China’s LNG (liquefied natural gas) ship equipment industry has achieved a milestone breakthrough.
On July 14th, Shanghai QiYao Environmental Technology Co., Ltd. (Qiyao Environ Tec) successfully completed the construction of the skids for the LNG cryogenic reliquefaction system of Jiangnan Shipyard’s 175K LNG carrier. The skid was then transported to a low-temperature test bench for onshore working condition tests, marking that China’s first large-scale cryogenic system for LNG carriers has entered the final verification stage. It is scheduled to be delivered to Jiangnan Shipyard in late August.
As a core supporting equipment for LNG carriers, the cryogenic reliquefaction system features high technical difficulty and has long relied on imports. Building on its accumulated experience in cryogenic systems for small-scale LNG carriers, Qiyao Environ Tec has optimized a number of key technologies, including dynamic simulation of cryogenic processes, high-power high-speed permanent magnet motors, five-degree-of-freedom actively controlled magnetic levitation systems, high-efficiency fluid machinery with a wide operating range, and highly compact, low-leakage skid integration.
Building on the technical expertise gained from this actual ship project, Qiyao Environ Tec will develop the capability to design and supply a series of cryogenic systems, providing critical support for the self-reliance and control of China’s LNG industry chain.
With the full advancement of onshore testing, Qiyao Environ Tec’s LNG reliquefaction project team will continue to leverage its leading advantages in scientific and technological innovation, accelerate the industrialization of core technologies, and inject new impetus into the high-quality development of China’s clean energy equipment.
