Facing the severe and complex epidemic situation across the country, Tunnel Co., Ltd. Shanghai Energy Construction insists on moving forward steadily and continues to steadily advance many key projects in the fields of oil and gas storage and transportation, and people's livelihood projects, including Dalian Natural Gas High-pressure Pipeline (Lvda Line) II The second phase bid, the second phase EPC project of the Qiandongnan Zhou County Natural Gas Pipeline Construction Project, the second bid section of the Shenyang old gas pipeline network renovation project in 2022, etc.
Dalian Natural Gas High-Pressure Pipeline (Lvda Line)
Phase II, Second Standard
Dalian Natural Gas High-pressure Pipeline "Lvda Line" project is a major livelihood project that the Dalian Municipal Party Committee and Municipal Government pay close attention to, with a total investment of 700 million, and the project is divided into two The first phase of Dalian Qianmenguan Station has been successfully completed. The main construction contents of the second phase include medium and medium pressure regulating stations, high-pressure pipelines, cut-off valve chambers, etc.
The second phase of the second bid section project, which is responsible for Shanghai Nengjian Oil and Gas Storage and Transportation Engineering Company, is from the Muchengyi pressure regulating station to the Sanchakou section. It is divided into one main line and two branch lines. A total of high-pressure pipes with an outer diameter of D711 and a design pressure of 4.0MPa will be laid. The pipeline is about 17 kilometers.
During the construction process, the Dalian Project Department of the Oil and Gas Storage and Transportation Engineering Company insisted on strict deployment and implementation, carefully followed the specific requirements of Dalian City’s epidemic prevention and control, and implemented closed management of the construction site. All workers must register and report through the “real-name system” , strictly check the "two codes" and conduct body temperature checks every day. At the same time, the site is regularly disinfected, and a series of effective measures are used to weave a tight and tight epidemic prevention and control security network in an all-round way, and actively strive to achieve both project progress and epidemic prevention. .
Faced with various uncertain factors in the epidemic, the Dalian Project Department of the Oil and Gas Storage and Transportation Engineering Company has made full preparations to overcome the shortage of manpower and material resources during the epidemic. It has mobilized and actively coordinated with multiple parties to strengthen the reserves of personnel, epidemic prevention supplies, materials and equipment in advance. and guarantee work, which effectively buffered the construction pressure caused by the epidemic and bought valuable time for the project to advance as scheduled.
So far, the second phase of the project has laid a total of 6 kilometers of pipelines and 535 anti-corrosion joints, with a pass rate of 98.47%. The project is expected to be completed and put into use before the end of 2022. By then, it will further enhance the natural gas supply capacity of Dalian's Lushunkou District, which is of great significance for promoting the rapid development of the local economy and society.
Qiandongnan Prefecture-County Natural Gas Pipeline Construction Project
Phase II EPC Project
The second-phase EPC general contracting project of the Qiandongnan Prefecture-County Natural Gas Pipeline Construction Project, which is undertaken by Shanghai Energy Construction Oil and Gas Storage and Transportation Engineering Company, is an EPC general contracting project implemented by Guizhou Province. "Several Opinions of the State Council on Promoting the Coordinated and Stable Development of Natural Gas", a key gas project to accelerate the construction of natural gas county-to-county connections in Guizhou Province, with a total investment of 720 million yuan.
The project consists of two lines, Huangping-Zhenyuan and Tianzhu-Congjiang. The length of the Huangping-Zhenyuan line is 65.51 kilometers, with a designed annual gas transmission volume of 78.43 million cubic meters; the length of the Tianzhu-Congjiang line is 184.09 kilometers. The designed annual gas transmission volume is 337 million cubic meters.
Faced with the test of parallel epidemic prevention and control and engineering construction, the Guizhou Project Department of the Oil and Gas Storage and Transportation Engineering Company did not shrink back or slack off. In accordance with the epidemic prevention and control requirements, a detailed and comprehensive epidemic prevention and control plan has been formulated, sufficient supplies of masks, alcohol and other epidemic prevention materials have been reserved, and closed management of the construction site has been implemented. All personnel must have their body temperature measured and check the itinerary code before entering the construction site. , health code, nucleic acid test report and real-name registration. Only after confirming that there are no abnormalities can you enter the site to carry out work.
While doing a good job in epidemic prevention and control, the project department also needs to overcome difficulties such as complex terrain and crossing canyons. In view of the pain points and difficulties in the project, the participating personnel carefully studied the site conditions, construction plans, technical support measures, etc. according to local conditions. Strengthen communication and coordination with relevant units, and on the basis of summarizing the previous construction experience, further optimize and improve the project plan, avoid "detours" in construction risks in advance, and ensure that the project construction is safe and on track.
The current project is progressing smoothly in accordance with the established goals. After the project is completed, it will greatly enhance the construction of the pipeline network in Guizhou Province, solve the long-standing historical problem of resource incoordination, improve the natural gas market system of Guizhou Province, and have a positive impact on the energy structure of Qiandongnan Prefecture. It is of great significance to optimize energy conservation and emission reduction, improve people's quality of life, and form a multi-gas supply pattern, which will speed up the construction of "gas-based Guizhou".
The 2022 Shenyang old gas pipe network reconstruction project
Construction of the second bid section
Shenyang old gas pipe network reconstruction mainly targets the gray cast iron pipes laid in the 1980s. The pipelines have been used for more than 30 years. The pipelines are seriously corroded and have potential Security risks.
Shanghai Nengjian Oil and Gas Storage and Transportation Engineering Co., Ltd. is actively involved in the task of transforming the old pipeline network and implanting the Shanghai gas pipeline network transformation experience into the local area. It has carried out 52 kilometers of old pipelines in the area south of Zhonghua Road and Shiyiwei Road in Heping District. The gas pipeline network was renovated, and helped the local area eliminate gas safety hazards and protect the safety of urban operations.
Since the impact of the epidemic has not yet completely ended, epidemic prevention work is particularly important when carrying out construction operations in Shenyang urban area. In order to ensure the safe and orderly progress of the project, the Shenyang Project Department has formulated strict epidemic prevention measures and emergency plans based on Shenyang City's specific requirements for epidemic prevention and control and in accordance with the work goal of "the project progress must not be missed and epidemic prevention safety must be paid attention to".
In view of the complex characteristics of the hidden danger pipe network reconstruction points being wide-ranging and concentrated in urban areas, the project department planned ahead and deployed carefully, closely connected with the owners, transportation and other relevant departments, formulated detailed construction plans and project promotion plans, and fully organized the construction forces , ensuring tasks are completed on time. After the completion of the
project, the original gray cast iron pipes will be replaced with more pressure-resistant and safer PE pipes or steel pipes, which is of great significance for further improving the safe operation and management level of the local gas system and effectively ensuring social stability and citizen tranquility.
