On September 28, the National Pipeline Network Group announced that the Fourth West-East Gas Pipeline The natural gas pipeline project has officially started construction. After completion, it will operate jointly with the second and third lines of the West-East Gas Pipeline to further improve my country's northwest energy strategic channel, effectively enhance my country's natural gas energy supply security capabilities, and better protect national energy security and economic security.
During the implementation process of the Fourth West-East Gas Pipeline Project, the scientific and technological innovation achievements in pipeline construction will be comprehensively promoted and applied based on the characteristics, difficulties and key points of the project. The first large-scale application of 18-meter extended pipes is expected to reduce the number of welds by more than 8,000, and the circumferential welds will be reduced by 33.3%, effectively improving the intrinsic safety of pipelines; digital radiographic detection technology (DR) is used across the entire line to realize automated detection data collection and digital storage ; Promote the construction method of double-connected pipes for large-diameter pipelines, saving 4 days of welding time per kilometer, and greatly improving construction efficiency. Strictly implement the "three simultaneity" system of simultaneous design, simultaneous construction, and simultaneous commissioning of environmental protection facilities and the main project. Supporting facilities and in-service pipelines are laid in parallel, and existing roads and facilities are prioritized to reduce resource waste and ecological damage.
The world’s first hydrogen metallurgy project Anshan Iron and Steel Group started construction < /div>
On September 27, the groundbreaking ceremony for the hydrogen metallurgy project of Anshan Iron and Steel Group was held at the Bayuquan Iron and Steel Base of Anshan Iron and Steel Group. This project is the world's first green hydrogen zero-carbon fluidized bed high-efficiency ironmaking new technology demonstration project. It has completely independent intellectual property rights and has achieved a breakthrough in the new low-carbon metallurgical technology route. It is of great significance to assist the green and low-carbon innovative development of my country's steel industry. significance.
This project adopts internationally advanced water electrolysis technology to achieve large-scale and efficient preparation of green hydrogen; develops new fluidized bed ironmaking technology to break through the problems of raw material applicability and reduction efficiency; integrates key technologies , to achieve continuous production of direct reduced iron with high metallization rate. The project is planned for 2023It was put into operation and formed a 10,000-ton fluidized bed hydrogen ironmaking project demonstration, providing a "Chinese solution" for the development of hydrogen metallurgical technology in the world.

my country’s largest liquefied natural gas reserve base was put into operation in Yancheng
On September 26, after a 16-day voyage of 6,000 nautical miles, the "Al Qashmiya" liquefied natural gas carrier from Qatar arrived in Yancheng, Jiangsu. my country's largest liquefied natural gas reserve base - CNOOC Yancheng "Green Energy Port" has begun unloading the first ship of liquefied natural gas, marking the project's commissioning.
The large-scale and rapid construction of LNG receiving stations benefits from the independent mastery of design and construction technology and my country’s strong infrastructure construction capabilities. Shi Chenggang, chairman of CNOOC Gas and Power Group, said that CNOOC was the first to enter the liquefied natural gas field in China, and independently developed and established 13 major technical systems such as intelligent new LNG receiving stations and new low-temperature storage, and mastered the world's largest 270,000 The design and construction capabilities of cubic meter storage tanks have reached world-class levels as a whole, pressing the fast forward button for the construction of my country's LNG receiving stations.

The first nuclear power heating project in Northeast China is about to be launched < /div>
The Liaoning Hongyanhe Nuclear Power Plant located in Wafangdian City, Dalian is the first nuclear power plant in Northeast China and the largest electric energy investment project in Northeast China. Recently, with six units put into full operation, it has become the nuclear power plant with the largest operating installed capacity in China and the third largest nuclear power plant in the world, with a total operating installed capacity of 6.7 million kilowatts. This winter, residents in the surrounding Hongyanhe Town will be able to use nuclear energy for heating through Northeast China's first nuclear energy heating project. The planned heating area reaches 242,400 square meters, which is more efficient than traditional coal-fired heating and has no carbon emissions.
The total investment of the Hongyanhe Nuclear Power Plant is nearly 90 billion yuan. Since units 5 and 6 of the second phase project were put into operation, the units have always maintained high-end and stable operation, effectively increasing the proportion of clean energy and optimizing Northeast China. The regional energy structure provides a steady stream of "green energy" for Northeast economic development.

Onshore construction of my country’s first offshore oil and gas equipment “intelligent manufacturing” project was completed
On September 23, It was learned from CNOOC Tianjin Branch that the Bozhong 29-6 oil field development project successfully passed the onshore construction completion acceptance at the COOEC Tianjin Intelligent Manufacturing Base, marking the completion of onshore construction of my country's first offshore oil and gas equipment "intelligent manufacturing" project. Important breakthroughs have been made in the digital and intelligent manufacturing transformation of offshore oil and gas equipment.
Since the construction started in October 2021, the project has for the first time applied production management information systems represented by digital intelligent manufacturing management systems, production execution systems, warehousing management systems, etc., and a large number of panels have been used A series of intelligent manufacturing technologies such as automatic cutting of profiles, robotic welding of deck pieces, intelligent grinding and assembly of H-beams, automatic grinding and welding of process pipe fittings, and intelligent warehousing break the information silos in each production link under the traditional manufacturing model and realize "production" in the construction process. It can be monitored, plans can be tracked, and quality can be traced.”
