[Haichuan Chemical News] China’s largest LNG carrier built to order delivered in Dalian, Liaoning
Thread Content
The 28,000-cubic-meter liquefied natural gas (LNG) carrier \"Zhongji Nenguan Global\", built by Dalian COSCO Shipbuilding Co., Ltd., set sail from Dalian, Liaoning on the 17th and was delivered to Zhongji Nenguan LNG Logistics Co., Ltd. for operational use. “The \"Zhongji Neng Huanqiu\" vessel is 176.8 meters long, 27.6 meters wide, and 18.5 meters deep. It is classified by the China Classification Society, and it is currently the largest LNG carrier with a single tank built by a Chinese shipyard. The ship is equipped with 3 Type C liquid cargo tanks, each with a maximum capacity of 10,000 cubic meters; when fully loaded, it can carry 28,000 cubic meters of liquefied natural gas, which, after vaporization, can supply nearly 100,000 residents for one year. The minimum design temperature for a ship’s liquid cargo tanks is minus 164 degrees Celsius, earning it the reputation of being a \"super freezer at sea\" in the industry. At present, the ship has set sail for China **. “After its delivery, the \"Zhongji Neng Huanqiu\" vessel will primarily operate in Southeast Asia, being used for round-trip transport between large liquefied natural gas receiving terminals and liquefied natural gas satellite stations.
During the construction period, the engineering and technical personnel at Dalian COSCO Shipbuilding successfully completed tasks such as the assembly and closing of the “gate”-shaped main structure, the lifting and installation of the liquid cargo tank bodies, the installation of variable-pitch propellers, and the installation of stainless steel pipes. During the gas testing period, the project team successfully completed the liquefied natural gas loading project in just over 50 hours. During the return trip with the cargo, Dalian COSCO Shipbuilding independently completed the commissioning of key equipment such as evaporator compressors and gas burners. To ensure the smooth construction of the ship, Dalian Port Customs established a working group from the initial stage of the project, providing on-site guidance on tasks such as the creation of the enterprise’s processing trade manual and the supply of marine spare parts. In advance, coordination was carried out with departments responsible for customs clearance and inspection, and a seamless customs supervision plan was developed to minimize the time required for customs clearance. This ensured that the materials could be imported without any delays and could be used for assembly promptly, thus facilitating the smooth progress of the entire project. Dalian COSCO Shipbuilding Co., Ltd. stated that the successful delivery of this vessel marked a breakthrough for Liaoning Province in the field of liquefied natural gas carrier construction, and served as a good example for promoting the wider use of liquefied natural gas as a clean energy source in transportation.
