What is the name of China s first self built icebreaker?

I built my own first icebreaker called "Snow Dragon 2".

"Snow Dragon 2" will be the name of the first icebreaker independently built by our country.

The first icebreaker in our country is called Sea Ice 722.

Haibing 722 icebreaker is the first generation of icebreakers of China's Haiduxiang Army, and also the first icebreaker in China, which was approved by the prime minister on September 14, 1969, built by Shanghai Qiuxin Zhenhu Shipyard, and launched on December 26, 1969.

The first generation of Sea Ice 722 icebreaker has a total length of meters, a maximum width of 16 meters, a full load displacement of tons, a draft of meters, two main engines of 2,600 horsepower, a maximum speed of 16 knots, and a cruising range of 10,000 nautical miles.

The second generation of sea ice 722 icebreaker is the first ship of the 272 type icebreaker designed and built by China, which started construction in November 2013 and was launched in March 2015, with a length of meters and a width of meters, a full load displacement of 4860 tons, a maximum speed of 18 knots, a wind resistance of 12 levels, a range of 7000 nautical miles, and a first-class platform that can take off and land a first-class aircraft.

Technical characteristics of Sea Ice 722

The Sea Ice 722 icebreaker appears "wide and fat" compared to other ships, in order to open up a wider channel and allow the ships that follow behind to navigate safely. The keel of the ship is thicker than other ships, the ribs are also thicker than other ships, the shell is particularly thick, and the hull is unusually strong.

Ships generally use copper propellers, but they are equipped with cast steel propellers that are extremely resistant to damage and are suitable for sailing in ice areas. Once the cooling water inlet at the bottom of the ship is blocked by sea ice and the external circulation cooling system cannot be used, the internal circulation cooling system will start to work to ensure the normal operation of the engine.

Science and Technology ** Beijing, September 26 (Reporter Chen Yu) "Snow Dragon 2" will become the name of the first polar icebreaker independently built by China. On the 26th, the relevant person in charge of the China Polar Research Center revealed to the science and technology reporter that on the same day, the ship began to be built continuously, and according to the plan, it will be completed in 2019, and will be together with the "Snow Dragon" icebreaker to form a team to help scientific research. At the end of last year, the groundbreaking ceremony of the newly built polar icebreaker was held at Jiangnan Shipbuilding (Group).

In order to maximize efficiency, the project adopts a resource management system to carry out all-round control of the project budget, procurement procedures, contract management, and use of funds, especially the use of computer modeling, first according to the basic design drawings to complete the whole ship modeling, and then modify according to the detailed design, as far as possible to solve the various process problems that may be encountered in the continuous construction stage in advance, reduce waste and rework, and greatly accelerate the construction speed. X0D X0AAW169 is one of the world's most advanced 4-5 ton medium-sized twin engines, which is expected to be delivered in early 2019, and will be used as a special shipboard for new ships in the harsh environment of the Antarctic and the Arctic. The bow and stern of the newly-built polar icebreaker can break ice, and the stern icebreaker can break through the 20-meter ice ridge in the polar region to meet the needs of navigation in the global unlimited navigation area.

In 1912, China built for the first time the icebreaker "Tongling" and the icebreaker "Kailing", both with a displacement of 410 tons and a power of 688 horsepower.

China's most powerful icebreaker - the Snow Dragon"Xuelong" (English name: Chinare), China's third-generation polar icebreaker and scientific research vessel, was built by the Kherson shipyard in Ukraine on March 25, 1993, a Vitas Bering-class icebreaker, the sister ship of the Xuelong is the Russian Vasiliy Golovnin. China imported it from Ukraine in 1993 and bought it at a low price of $17.5 million, and then the shipyard was renovated and completed on March 25, 1993 according to Chinese demand.

Nearly 200 million yuan has been invested in the renovation of the "Snow Dragon", and according to the relevant domestic authoritative estimates, the current price of the ship should be about 700 million yuan.

The "Snow Dragon" research ship is China's largest polar research ship and the only Chinese ship that can break the ice in the polar regions. The Xuelong ship is cold-resistant, can continuously break through the meter-thick ice layer (including rice snow) at a throttling speed, has advanced technical performance, is at the international leading level, and is also the only fully functional icebreaker in China for scientific expeditions in the polar region.

Snow Dragon Encyclopedia Introduction.

At the moment there is only the Snow Dragon, and now a new icebreaker is being developed.

First of all, it is certain that our country definitely has the technology to create icebreakers. Because the icebreakers currently used by the Chinese Navy are all domestically produced, they have played a huge role in the fight against ice conditions in the Bohai Sea. A brief introduction is as follows:

China currently has 5 large icebreakers. The three icebreakers approved by the state all belong to the Chinese People's Liberation Army Navy, and their board numbers are numbered as "Sea Ice 721", "Sea Ice 722" and "Sea Ice 723" according to the order of design, construction and launching. An icebreaker belonging to Yingkou New Port (Bayuquan Port) was named "Yinggang 12" icebreaker.

An icebreaker belonging to the Tianjin Waterway Bureau was named "Jinhang Tug 8" icebreaker. These five icebreakers were all designed and built by China itself. China's first icebreaker, the C722, was designed and built by Shanghai Qiuxin Shipyard in 1969 and was successfully launched on the afternoon of December 26, taking only three months.

For the birth of China's first icebreaker C722, a grand launching ceremony was held, which performed well in sea trials and was soon put into service.

At present, there are dozens of port tugboats with certain ice-breaking capabilities in northern ports such as Tianjin Tanggu Port and Qinhuangdao Port. The "Tianjin Hang Tug 7" belonging to the Tianjin Waterway Bureau is a large port tugboat with a single engine of 1,200 horsepower, designed and built by Shanghai Shipyard, launched in 1969, and responsible for the icebreaking of the Haihe River channel.

However, it is worth mentioning that due to the low latitude of China's sea area, the winter ice is much thinner than that of the high latitudes of Russia, so the icebreaker ships manufactured are suitable for use in the coast and river estuary, so China will import a special "polar" icebreaker from Ukraine and convert it into a research ship. This is also appropriate from an economic point of view, if only one polar icebreaker is built, then the cost of self-development will inevitably be greater than that of outsourcing.

However, with the increase of China's attention to the open sea, especially the Antarctic and Antarctic waters, China will definitely build a "domestic" polar icebreaker on its own in the future to replace the current Snow Dragon. After all, a boat built with its own technology is comfortable to use.

1. Antarctic scientific expeditions are mainly in the summer of Antarctica, and they are basically withdrawn in winter, after all, they cannot survive in the harsh winter of Antarctica.

2. The scientific research ship is enough, so there is no need to build a new one now. At that time, China spent more than 10 million US dollars to buy it, which was much cheaper than making it yourself, and it was able to learn a lot of technology.

3. Steel and engine technology are still relatively backward, but the Snow Dragon, an icebreaker built in the 90s, is basically not difficult to build now.

As for the resources of Antarctica, no country is qualified to exploit them, but only to conduct scientific exploration.
