China's first large cruise ship under construction is expected to be delivered before the end of this year, and the domestic large cruise ship is also known as the "No. 1 Project" in China Shipbuilding Group. How difficult is it to build this ship? Let's find out.

Realize designs such as smart security in limited spaces

CCTV reporter Li Ning: In order to build such a sea giant, Waigaoqiao Shipyard has renovated the original dock, which is currently equivalent to 7 standard football fields, which is the largest dock in Asia. After the first ship is undocked, the second cruise ship will enter the dock synchronously, and eventually this dock will be built on a rolling basis.

The first domestic large cruise ship installed more than 2500 million parts, which is 919 times that of the C5 large aircraft and 13 times that of the "Fuxing" high-speed rail.

CCTV reporter Li Ning: How to ensure the normal operation of such a sea giant relies on these cables behind me, which are like the nerves and blood vessels on this ship, its total length is more than 4300,<> kilometers, which is farther than the distance from Harbin to Sanya.

Director of China Ship Waigaoqiao Shipbuilding Cruise Office Deputy Manager of Large-scale Cruise Engineering Project Yi Guowei: The cable should provide control signals, this ship is also an intelligent ship, all the entertainment facilities and lighting facilities used on it can be controlled by the central control system.

During the construction process, not only is the cable arrangement complicated, but the cruise ship construction is also extremely weight-sensitive. The first domestic cruise ship weighs about 6,5 tons, and every 1 ton increase in its own weight means that the number of boarding materials or people will be reduced. At the same time, the first domestic large cruise ship also designed a unique redundant backup system.

Build a ship

Let the "passing economy" move towards the "industrial chain economy"

Compared with ordinary ships, the construction of cruise ships involves dozens of professional fields such as hotel engineering and entertainment systems in addition to shipbuilding technology. It can be said that the construction of a cruise ship has driven the development of the entire industrial chain.

On the ship, the reporter met Lian Zhen, the chief engineer in charge of the interior decoration of the cruise, and she told the reporter that she had participated in the decoration design of countless land hotels, but it was the first time that the decoration on board was the first time.

According to Lian Zhen, the interior of the cruise ship is different from ordinary architectural decoration, whether it is materials or appearance, etc., there are strict international standards. In order to build the first large-scale cruise ship, Waigaoqiao Shipbuilding has attracted more than 500 global suppliers across industries and regions, and has established cooperation with 54 service providers from the United States and Italy in the field of cruise interiors.

Chen Gang, General Manager of China Shipbuilding Waigaoqiao Shipbuilding and Chief Designer of Large Cruise Project Chen Gang: It is actually a transnational cooperation and multi-party cooperation, whether it is design, construction, procurement, it is an international one.

Chen Gang said that in the process of cooperation, it has also promoted the improvement of relevant technical capabilities of domestic manufacturers.

Lian Zhen, Chief Engineer of Shanghai Construction Decoration Group: For example, steel fire doors, we are now looking for the best steel fire door manufacturers in our onshore buildings, jointly production, education and research, constantly doing experiments, and then sending them to these internationally recognized laboratories to obtain reports.

Guided by the construction of cruise assembly to promote the development of the entire cruise industry chain, it is an important purpose to build a domestic large-scale cruise ship. Cruise ship construction can bring 1:14 promotion to shipbuilding, home ports, retail and other related industrial chains.

Yi Guowei, Director of China Ship Waigaoqiao Shipbuilding and Cruise Office Deputy Manager of Large Cruise Engineering Project: After customers board and disembark, they will also carry out corresponding consumption and entertainment in the local area, so the economic pull of the home port of the local port is also relatively obvious. If China's cruise industry continues to develop at a normal pace, it is estimated that it can reach an annual output value of 2035 billion yuan in 5000.
