Domestic large cruise ships realize "two -wheel" simultaneous creation

Xinhua News Agency, August 8th (Reporter Jia Yuanzhang) On August 8th, the second domestic large -scale cruise ship was constructed at Shanghai Waigaoqiao Shipbuilding Co., Ltd. ("Waigaoqiao Shipbuilding") in China Shipbuilding Group, marking a large domestic large -scale large -scale domestic large -scale Cruises enter the era of "two -wheeled".

The domestic large -scale cruise ship has fully entered the stage of key interior and system completion and commissioning. It is planned to be delivered in 2023. On the basis of the first ship, the technological innovation, construction process, and supplier management of the second domestic large cruise ship will be improved.

The second domestic large cruise ship has optimized on the basis of the first ship -made, which is concentrated in changes in "more" and "less".

"More" is reflected in large volume, many functions, and high requirements. The total tonnage of the second domestic large cruise ship is about 142,000 tons, 341 meters long, and 37.2 meters wide. Compared with the first ship, its total tonnage has increased by 06,700 tons, the total length is increased by 14.4 meters. The total number of rooms reaches 2144.

The second domestic large cruise ship is also equipped with up to 16 -storey upper building life and entertainment areas with large performing arts centers, large restaurants, specialty restaurants, bars, cafes, shopping squares, art corridors, children's centers, SPA, water park, etc. Rich leisure and entertainment facilities.

"Less" is reflected in the construction cycle that is greatly shortened and the progress is faster. Compared with the first ship, the design and construction cycle of the second domestic large cruise ship has been compressed for 6 months. At present, about 40%of the detailed design has been completed.

According to Yi Guowei, director of the Cruise Office of Shanghai Waigaoqiao Shipbuilding Co., Ltd., the requirements of large cruise ships in thin plate welding, total segment assembly and installation, multi -professional collaboration, process management and delivery, and giant system debugging are significantly higher than Other ships, high -efficiency production of European mature cruise ship factories, have also been realized after years of optimization.

Large cruise ships represent a national equipment construction capacity and comprehensive technology level. The behemoth of 25 million components, the management of materials, components, and equipment systems can form a huge database. Although large cruise ships are large, there are many internal systems and complex interaction. The layout of various pipeline systems and integrated debugging between systems are "fine work".

First of all, look at the shape. The most basic hull construction part of the ship faces the challenge to make the construction error of this "sea giant" of no more than 20 mm. This kind of lean refinement not only ensures the safety and reliability of the hull construction, but also shaped the "perfect line" of the hull.

Waigaoqiao Shipbuilding specially built on a thin plate production smart workshop for domestic large cruise ships. With the MES system as the core, with the industrial Internet technology, the intelligent control of the production line is realized, the level of segmented construction efficiency and accuracy management is guaranteed to ensure the accuracy of the hull construction construction High -efficiency.

Secondly, how much physical space can be divided into large cruise ships that can accommodate thousands of people? In order to meet the requirements of the project delivery, the first large -scale cruise ship -made ship implements codeized management of the entire functional area of ​​the entire ship in accordance with the smallest physical separation unit. According to the regional functional attributes Essence

The construction of the first large -scale cruise ship's first ship -made ship gradually sorted out the specifications, technical points, and risks of carriers, and overcome the professional deployment difficulties with small and many space in the cabin area, and basically mastered the various special design technologies of luxury cruise ships.

Large cruise ships are the "messenger" of navigation culture and the "artwork" of Jina's global ship industry wisdom. Due to open cooperation in large domestic cruise ships, the "new map" of global cooperation is outlined.

The construction of the first ship bearing the important responsibilities that affect the development of the industrial chain. Through establishing a strategic cooperation relationship with 101 suppliers worldwide, the full process cooperation of design, raw materials production, on -site construction, and commissioning and delivery has been realized. It is the second domestic large -scale large -scale large -scale large -scale large -scale large -scale large size The construction of cruise ships laid the foundation.

Waigaoqiao shipbuilding also attracted more than 500 global suppliers across the industry and across regions to promote the design and construction of cruise ships, especially in the field of cruise in the field of cruise, and cooperates closely with 54 service providers from the United States and Italy.

If global cooperation expands horizontally, then independent innovation is vertical and deeper, and the two complement each other and promote each other. On the day of the start of the second domestic large cruise ship, the large cruise innovation center was established in the outer Gaqiao Bridge. More than 40 superior enterprises have settled in more than 40 industrial chain. "Innovation -driven industry development, industrial development drives innovation, large cruise innovation centers can gather more innovative results, and provide strong support for key core technologies for large cruise ships." Zhou Qi, the chief builder, said.
