On May 31st, our company and Changxing Shipyard No. 2 Dockyard were busy. Under the tugboat's traction, two 174,000 cubic meter LNG ships slowly sailed out of the dock, and the other two large LNG ships completed the floating and shifting operations. This is the second time since March 24 that the company has built four ships simultaneously, two ships have been docked, and two ships have been floated. The docking period has been shortened by nearly 20% year-on-year, reaching the world's advanced level. It marks that the company's four-ship parallel and semi-series construction model in the large-scale LNG dock has entered a new stage of batch, normalization, standardization and rhythm, and the LNG ship capacity doubling strategy has entered a new realm of comprehensive acceleration.

In order to further improve the efficiency of large-scale LNG ship construction and shorten the shipyard cycle, our company included the new model of four-ship parallel and semi-tandem construction in the annual process and construction method innovation project at the beginning of this year, and carried out key planning and deployment.

During the implementation process, the company relied on a series of measures such as technological innovation, intelligent manufacturing support, digital process optimization and rapid shipyard loading to continue to strengthen production organization, node assessment and process control. The LNG ship project team is working together as a team, with the spirit of being brave in innovation and daring to make breakthroughs, constantly promoting refined project management, overall planning of shipyard resources, balancing the quantity of each ship, identifying construction risks and difficulties, and preparing production plans for each ship, so as to " Through careful management and precise production, we achieve twice the result with half the effort.

Under full-load construction, after 68 days of hard work by the project team, the docking period was shortened by 20%, achieving the set goal of achieving the best integrity of the entire ship and structural performance of the half-ship in history. The project team worked closely together and worked in the same direction, and the hull and outfitting coating of the main shipyard section was further improved. The superstructures of the two entire ships began polishing the cabins before the general assembly was hoisted. The insulation of the superstructures began to be installed before undocking. The B deck arrived. The installation of the cab windows has basically been completed, the cable laying of the whole ship has reached more than 55%, and the tightness of the pipeline installation of the whole ship has reached more than 20; the four cargo holds of the two and a half ships have been delivered for the construction of the containment system before being floated, and the overall integrity has been improved. obvious. The construction team worked hard to accumulate experience and build confidence for the continuous consolidation and optimization of batch, normalization, standardization and rhythm of parallel and semi-series construction in large-scale LNG docks.

The two ships undocking this time are both fifth-generation "Changheng series" LNG ships designed and developed by our production products. They have a total length of 299 meters, a molded width of 46.4 meters, and a molded depth of 26.25 meters. Equipped with a number of low-carbon and energy-saving technologies, compared with the previous generation of LNG ships, it has the characteristics of low overall energy consumption, good low-temperature performance, strong cargo carrying capacity, and smart operation and maintenance. It can reduce carbon emissions by more than 10 tons in a single day of navigation, making it accessible There are 120 LNG shore stations on all continents around the world, with excellent global navigation.

As the company's LNG ship production capacity doubling strategy becomes more and more effective, the advantages of large-scale LNG ship construction will be further highlighted, and the company's competitiveness in the global large-scale LNG ship construction field will also become stronger.
