CCTV News: The reporter learned from China Shipbuilding Corporation that on April 28, my country's second large domestic cruise ship "Aida Huacheng" completed its dock, marking that the overall progress of the cruise project has been completed by more than 70%, and it has been fully transferred to the internal installation and system completion and debugging stage.

At 1:30 a.m., in the dock of the Waigaoqiao shipbuilding in Shanghai, as the command to "open the gate and release the water" was issued by the staff, sea water poured into the dock. After 6 hours of water injection and real-time observation in the dock, the cruise ship slowly floated up, and the second large domestic cruise ship completed the milestone node of floating in the dock. Subsequently, the staff conducted a series of key process elements and technical indicators such as residual stress release of the entire ship and measuring the weight center of gravity, and further systematically verified the major scientific research achievements achieved by domestic large cruise ships in the stages of design, process, assembly and construction, which can be called a "midterm exam".

Chen Gang, the on-site commander-in-chief of Waigaoqiao Shipbuilding and domestic large-scale cruise projects of China Shipbuilding Group, said: "The rise and fall of the No. 2 cruise ship is very smooth, and all indicators are within our expected range. Structural assembly includes pipelines and cables. These installation work has come to an end, and it has entered the later stage of system debugging preparation and the comprehensive start of the interior construction project, and has moved to a new stage."

According to the plan, the second large domestic cruise ship will go to sea for trial voyage in May 2026 and is scheduled to be delivered by the end of 2026. Experts told reporters that the second large domestic cruise ship must pass 108,000 full-ship inspection before delivery. Unlike the first large domestic cruise ship, the second ship's supervision team has also been replaced by a foreign team to a Chinese local team.

Niu Zhichun, deputy manager of the "Ida Huacheng" project supervision and construction team of China Ship Cruises, said: "The on-site supervision and construction team covers all the work of 7 majors in a total of 7 majors, including hull, turbine, electrical appliances, paint, etc. Our task is to ensure that the design requirements are implemented on the actual ship, and at the same time ensure that our construction progress meets the requirements of the shipowner. At present, more than 31,000 items have been completed, and the design drawing review has been completed by 97%. "

The domestic production rate has been improved, and the construction speed has been accelerated by 30%. > Compared with the first domestically produced large cruise ship "Ida Huacheng", the second large domestic cruise ship "Ida Modu", not only has a larger hull size, but also has higher construction efficiency. How did this be done?

Compared with the first large domestic cruise ship, the second large domestic cruise ship "Ida Flower City" is 17.4 meters longer and is equipped with a living and entertainment area of ​​up to 16 floors. The areas of public areas and outdoor activities and leisure areas increased by 735 square meters and 1913 square meters respectively, with a total tonnage of 141,900 tons.

Chen Gang said: "The captain of the No. 2 cruise ship has been lengthened by 17.4 meters, so the total tonnage has increased by 6,400 tons. We have reflected and re-planned the design, procurement, construction and craftsmanship of the entire "Ida Magic City", and continuously built digital management and control capabilities and design methods. It is expected that the construction hours of the No. 2 cruise ship will be shorter than that of the first ship in total."

In Shanghai Waigaoqiao Shipbuilding, the reporter saw that through digital transformation, staff can grasp the installation status of more than 25 million parts of the ship with a tablet computer. The addition of artificial intelligence also allows the virtual model of the second large domestic cruise ship to be updated in real time. At the same time, the improvement of the domestic production rate has greatly accelerated the construction efficiency.

Chen Gang said: "Since the second cruise ship, we have systematically promoted the localization. The balcony project, including the stage lifting system and entertainment system in the theater, has been the first to achieve localization, which is 5% higher than the first ship's domesticization rate. The improvement of localization is also a promotion for production efficiency. In the next 10 years, the domesticization rate of the entire cruise equipment industry has reached 80%. How to achieve the goal of achieving the domesticization rate in stages has been preliminarily formulated, and we have begun to move forward step by step."
