Recently, the third 174,000m3 large liquefied natural gas (LNG) transport ship project called "Kunlun" was delivered and named at the Changxing Island No. 0 Base in Shanghai.
This vessel was built by Hudong-Zhonghua Shipbuilding (Group) Co., Ltd. for COSCO Shipping CNPC State LNG transportation project and was inspected and reviewed by China Classification Society (CCS).
"Kunlun" is classified as a CCS ship and is the fourth generation "Changxing" series LNG ship of Hudong-Zhonghua Shipbuilding (Group) Co., Ltd. The vessel has a total length of 29m, a molded width of 45m, and a molded depth of 26.25m.
The ship is equipped with a mature manufacturing technology of membrane cargo tank and the latest generation of dual-fuel low-speed propulsion power systems in the world. The vessel is designed with advanced environmental protection devices and can meet the strictest emission standards of the International Maritime Organization (IMO) in gas and fuel modes.
Additionally, it is equipped with highly integrated automated cargo control and driving control, engine room control systems, and has been awarded the green ship environmental protection and additional signs for unmanned engine rooms.
During the design and drawing review phase of the 174,000m3 COSCO Shipping CNPC state LNG transport ship, Shanghai Rules & Research Institute completed the verification of overall longitudinal strength and descriptive requirements of hull beams, direct calculation of yield and buckling strength assessment for cabin sections, and fatigue strength assessment.
The institute also carried out advanced analysis and assessment of LNG ships including overall strength assessment, fatigue spectrum analysis, and pump tower vibration assessment, providing valuable suggestions for the design optimization of the project and laying a solid foundation for the subsequent construction of the project.
After the "Kunlun" ship is put into operation, it will form an LNG maritime transportation matrix in China along with "Shaolin" and "Wudang" ships delivered last year. This effort will enhance China's LNG fleet capacity and achieve the security of China's LNG energy industry chain and supply chain.
Technical highlights of the 174,000 m3 large liquefied natural gas (LNG) transport ship project:
- The new generation NO.96 L03+ cargo system is adopted, which is featured with low evaporation rate and good route adaptability.
- XDF dual-fuel propulsion system is adopted, which has a configuration higher than international mainstream, and is featured with low energy consumption and strong reliability.
- Both the host and the generator are equipped with the Selective Catalytic Reduction (SCR) device to fully meet the world’s strictest environmental requirements.
- Strong ship shore compatibility for good docking with the Floating Storage and Regasification Unit (FSRU) and good global universality.
- It can meet the rules and regulations by 2025, and the Energy Efficiency Design Index (EEDI) reached the third stage in advance, with good foresight and strong market vitality.
- An energy-saving cargo handling system design for low comprehensive energy consumption and excellent economy.
