【Ten Years of Rapid Development in Chemical Processing Equipment】China’s First LNG Ship Refueling System with Fully Independent Intellectual Property Rights, 1997–2023
Thread Content
Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with you all; we welcome everyone to engage more in discussions on this forum. Happy May Day! A safe and secure Red May ********************************************* Recently, the LNG ship refueling system (STS) developed by Shanghai Qiyao Power completed its system integration tests. Under low-temperature conditions of liquid nitrogen (-196°C), it was able to achieve rapid docking and safe separation, making it China’s first LNG ship refueling system with entirely independent intellectual property rights. This system obtained the first AiP certification from DNV in China in 2021. It includes components such as emergency disconnect devices, dry quick connectors, composite low-temperature hoses, ship distance monitors, and descent saddles, and is primarily used in applications such as ship-to-ship LNG refueling at sea, ship-to-ship LNG transfer, shore-to-ship LNG refueling, and ship-to-shore LNG refueling. The test system in question is a large-diameter DN200 ship refueling system; by simulating the conditions of a ship separating at sea, it can respond quickly and issue alarms, enabling emergency disconnection within 2 seconds as well as the safe lowering of the hoses. Even after separation and drop, it maintains good sealing without any leaks.

The Jerry LNG ship-to-ship refueling system is located on the bow refueling station platform, installed on both the starboard and port sides. Its designed refueling capacity is 1,650 cubic meters per hour. It includes systems such as an emergency disconnect device, quick-connect fittings, low-temperature hoses, a ship-to-ship distance detection system, saddles, and fall prevention measures, enabling safe and rapid LNG refueling between ships. It features a high refueling flow rate, high safety and reliability, and strong adaptability to various environmental conditions. China State Shipbuilding Corporation stated that as the first domestically produced equipment to be used in actual ships in China, the Jerey LNG ship-to-ship refueling system has successfully broken the foreign technological monopoly. For the first time, this entire system achieves \"domestic production of key components + independent control over core technologies,\" thereby enhancing the capacity for domestic production within China’s offshore LNG industry chain. As reported by IT Home earlier, China has made new progress in the development of ships equipped with interchangeable LNG fuel tanks. The first batch of 40-foot interchangeable LNG fuel tanks developed by CRRC were installed on the 5,000-ton class liquefied natural gas (LNG)-powered container ships, the Hongyuan-Xuzhou and Hongyuan-Wuhan, which then set sail from the ports of Xuzhou; this marks the beginning of commercial use of interchangeable LNG fuel tanks in Chinese ships.
