Through the sky, the land will be expanded. Since the 18th National Congress, China has successively experienced leapfrogging in the road to the world's technological powerhouse after experiencing the baptism and tempering of a series of major projects such as "Eye of the Sky", Shenzhou Feitian, and "嫦娥". Looking at the Wanli River from the top of the nine days, after more than five years of technological transcendence, the reforms of the rise of China's land have led to a new historical starting point for national science and technology.
The world's first permanent magnet motor drive shield machine was launched in China. The high-speed rail C3 train control system with complete independent intellectual property rights was successfully developed. The world's longest desert Gobi highway construction was completed, and the world's advanced EMU trains were reached. The Fuxing is driving out of "China's speed"... China's heavy equipment technology level has been tracked and tracked into a new stage of tracking and running and leading. The state is the first country. Looking at this difficult and tortuous road to innovation, the company writes a page of glorious chapters with the theme of "rejuvenating the country."
Seize the "bearing heights"
"In China's development to the present stage, not only is it impossible to get key core technologies from others, but it is also difficult to get general high technology, so our foothold must be placed on independent innovation." The situation, General Secretary Xi Jinping pointed out. State-owned enterprises firmly follow the road of independent innovation, which is the inevitable way to seize the market opportunities and the natural mission of safeguarding national security.
For a long time, China's heavy equipment manufacturing relied on foreign technology imports, and many products could not be produced independently and subject to people. With the goal of localization, China Railway Construction 601186, the stock bar heavy industry group Co., Ltd. (hereinafter referred to as Tiejian Heavy Industry) bravely shouldered the core force of China Railway Construction to become a strong industrial giant, and successfully built roadheaders and special equipment.

"falling the sea"
In the ocean of the 21st century, China is like a superstar rising. Behind the rise of the great powers is the source of power and strong support for the “Ocean Power†strategy. With Haixingguo, the report of the 18th National Congress of the Communist Party of China first proposed: improving the development capacity of marine resources, developing the marine economy, protecting the marine ecological environment, resolutely safeguarding the national maritime rights and interests, and building a maritime power.
Marine technology characterized by deep water, green, and security is the commanding height of the maritime power. In recent years, state-owned enterprises have taken root in this vast "blue country", aiming at technological bottlenecks and industrial transformation shortcomings to catch up, and have successively cultivated "Ocean Oil 981", intelligent ship "I-Dolphin", and the Dragon Boat Manned A group of scientific research achievements such as submersibles have continually stimulated the potential of transforming marine resources into economic advantages.
|
The ocean power is close at hand. Sailing the commanding heights of marine technology, the "super" fleet of state-owned enterprises is breaking the waves.
Exploring the deep sea
Deep into the ocean, the secret is unpredictable. In the long history of history, human beings are constrained by modern technology and are deterred from the deep sea space. Today, the rapid development of deep-sea exploration technology provides a guarantee for human beings to broaden their borders. Exploring the deep sea, a piece of deep-sea weapon created by state-owned enterprises constantly refreshes the imagination of science and technology.
The ocean contains more than 70% of the world's oil and gas resources. The world's deep water reserves have a potential potential of 100 billion barrels. Deep water is an important replacement for the world's oil and gas. In recent years, China National Offshore Oil Corporation (hereinafter referred to as CNOOC) has strengthened the construction of deepwater equipment and technical capabilities to meet the needs of developing deepwater oil and gas. After six years of careful research, design and construction, China’s first self-designed and constructed The six-generation 3000-meter deep-water semi-submersible drilling platform "Offshore Oil 981" was officially completed.
“Ocean Oil 981†has a maximum working depth of 3,000 meters and a drilling depth of 10,000 meters, representing the highest level of offshore oil rig technology in the world today, filling the gap in the design and construction of deepwater drilling platform equipment in China.
As an important “vehicle†for human beings to explore the mysteries of the deep sea, deep-sea manned submersibles can perform complex tasks such as exploration of submarine resources, fixed-point deployment of underwater equipment, submarine cable laying and pipeline inspection. In June 2012, China Shipbuilding Corporation 600150, the stock bar heavy industry group company (hereinafter referred to as CSIC Heavy Industry, the manned deep submersible manned deep diving potential reached a maximum depth of 7062 meters, making China the world's similar manned diving In the country with the deepest dive depth, a large number of deep-sea exploration equipment such as the "Qianlong" series AUV, "Hailong" ROV and "Haima" ROV emerged.
For the benefit of the people
The marine space is rich in resources such as biology, energy and minerals. The development of the marine industry for the benefit of the people has become the top priority for the sustainable development of the national economy. The gratifying achievements of state-owned enterprises around seawater efficient use, natural gas hydrate test mining, and large-scale liquefied natural gas (LNG) vessels have continuously turned the marine economy into a reality.
Water is the source of life. In China, where per capita water resources are only a quarter of the world average, desalination is an important way to alleviate water shortages. As one of the earliest companies involved in the field of desalination in China, SDIC Development and Investment Co., Ltd. took Tianjin Jinneng Power Generation Co., Ltd. (also known as “Guotou Beijiang Power Plantâ€) as a breakthrough, and carried out independent innovation in depth, so that China gradually got rid of it. Key technologies are subject to the human situation. At present, the scale of desalination water in the first phase of the project in northern Xinjiang has reached 200,000 tons/day, accounting for 1/5 of the total amount of desalinated water in the country.
With the increasingly tense oil and gas resources on the land and the intensified contradiction between the world's energy supply and demand, the development and competition for marine resources by all countries is unprecedentedly fierce. In the South China Sea, a breakthrough in technology has once again rewritten the energy landscape.
On the afternoon of July 9, 2017, the natural gas hydrate (hereinafter referred to as combustible ice) test site at the Shenhu sea area in the northern part of the South China Sea was officially closed. PetroChina 601857, the stock bar natural gas company was actively involved in the combustible ice mining experimental project, and undertaken the project's engineering design, test mining operations and construction operations, accumulatively involved in gas production of more than 300,000 square meters, the longest continuous gas production time A number of major breakthroughs such as the largest amount of production, stable airflow, and environmental safety have also created two world records for gas production time and total gas production.

The exploitation and transportation of marine energy is inseparable from the vigorous development of marine equipment technology. China State Shipbuilding Corporation has broken through a number of key core technologies for high-end marine equipment. Among them, “China Shipbuilding Group High-end Marine Equipment Technology Innovation Project†won the second prize of National Science and Technology Progress Award (Enterprise Technology Innovation Project). It has established the status of “China's only and world-class†in the design and construction of large-scale liquefied natural gas (LNG) vessels.
Sea and land
Marine development relies on the strength of marine engineering construction. At present, accelerating the development and utilization of coastal zones, China's seas and ocean resources, accelerating the pace of port economy and regional economic development, has become one of the important measures to implement the strategy of strengthening the country. In this vast blue ocean, some traditional manufacturing and construction companies are constantly extending their reach to the ocean, and they have also achieved remarkable achievements.
Yangshan Island, an ordinary small island above the East China Sea, is the world's largest island-type artificial deep-water port Yangshan under the ever-changing magic of China Construction Engineering Corporation's China Construction Port Construction Co., Ltd. Deep water port. Since the construction of Yangshan Port, the headquarters of China-Hong Kong Port Yangshan Project has been dedicated to building a new elevation for domestic hydraulic engineering construction. Three construction methods have been awarded the national first-level construction method, and six construction methods have been rated as the first-level construction method for the water transportation project of the Ministry of Communications.
As far as the difficulty of construction is concerned, the Hong Kong-Zhuhai-Macao Bridge is even worse than it. This "world engineering miracle" is a submarine tunnel consisting of 33 180-meter-long, 74,000-ton-long immersed pipes at a depth of 50 meters and tens of thousands of tons of water pressure. Communicate with the world's largest cross-sea cluster project. China Communications Construction Co., Ltd. has made the Hong Kong-Zhuhai-Macao Bridge, known as the “super projectâ€, a reality through independent innovation and the world's leading immersed tunnel technology.
Pipeline steel is a star product of Angang Group. In the national key projects such as the West-East Gas Pipeline, the Shaanxi-Beijing Second Line, the Sichuan-East Gas Pipeline Project, and the Sino-Russian Crude Oil Pipeline Project (first-line and second-line), the anesthesia steel pipe line steel is active. From the land to the bottom of the sea, Angang has a special environment with complex seabed environment and high pressure, and the pipeline is greatly affected by the surge. According to the owner's requirements, the maximum width of the steel plate to be supplied must reach 3,724 mm. This is the Asian submarine pipeline so far. The largest wide-area pipeline steel plate for engineering supply.
In June 2017, the Angang Steel Pipeline was incarcerated in the “Nanlong†to explore the South China Sea, making the largest pipeline submarine pipeline in Asia once successful. This is another result of the Angang Group’s strategy to support China’s maritime power.
