Jiaozhou Bay Sea Underwater Gas Pipeline, "Land and Sea Connection"!

Land and sea connected, the natural gas pipeline of Jiaozhou Bay Underwater Pipeline Land to the Hai Ding to complete the super long tube section back

For the most important control project of the entire project, the three "firsts" in China

Qingdao Daily/Guanhai News August 10th. The construction site of the land -sea drilling drilling of the Underwater Pipeline of Zhenping Road, Shibei District. Under the coordinated operation with maritime operating ships, slowly enter the ground, and advance towards the target point towards Jiaozhou Bay. After 90 hours of continuous operation, the crossing was successfully completed at 3 pm today, and a number of technological breakthroughs in the construction of large -caliber urban gas pipeline projects in China.

Under the coordinated operation of the 800 -ton pushing machine and maritime operating ships, the long pipeline completes the cross from land to the bottom of the sea to achieve land and sea connection.

According to Bi Hongbo, deputy general manager of Qingdao Energy China Resources Gas Co., Ltd. and the manager of the natural gas pipeline project department of Jiaozhou Bay, Lu to Haiding to Hai Dianding is the key node of Lu Hai Guantong, the Jiaozhou Bay Sea Management Project, and the most important thing in the entire project. Control engineering. "Since the construction of the sea management, with the joint efforts of the participating units over 5 months, the ultra -long land -to -sea drilling site, pipeline prefabrication, guide hole drill, pores and holes washing, pipeline prefabrication, guide hole drilling, pipeline pipelines, guide holes, and pores were completed. Waiting for work, eventually have the condition of recovery. The completion of the land -sea directional drill back to the drag operation is a milestone in the construction of the Jiaozhou Bay Sea Pipeline, laying the foundation for the entire line of the Underwater Pipeline of Jiaozhou Bay.

According to Li Ming, the person in charge of the Ocean Company of the Ocean Company of the Ocean Corporation of the Ocean Pipeline Bureau of the project construction party, the length of the land -to -sea drill is 1402 meters and the maximum depth of the drilling hole is 45 meters. The directional diamond is a new technology and new process, with tight time and technical difficulty. In order to ensure the successful crossing, the project's participating party planned coordinated planning, analyzed various difficulties and risk points in detail, organized well -known domestic experts to repeatedly demonstrate, repeatedly deduced desktop, continuously optimized the construction plan, controlled potential risks advance Measures and emergency plans. "This time Lu's construction of Haiding to the diamonds created the three domestic 'first': This is the first land -to -Haoding diamond drill in the domestic gas pipe diameter in China. The depth of the depth of the sector to the drill of the Haiding is up to 45 meters, and the geology is complicated.

"Since August, the construction of the natural gas pipeline under the Underwater Underwater of Jiaozhou Bay has blossomed more." The person in charge of the project department of Jiaozhou Bay Underwater Pipeline project said. "Now that the sea section is more than half of the pipelines, the land section of the land has completed the welding of 20 kilometers of pipelines, and the ink river crossing is completed. The longest Dagu River crossing construction is about to enter the implementation stage. "Bi Hongbo said.

Qingdao Jiaozhou Bay Underwater Gas Pipeline Project is an important energy basic supporting project in our city. It is included in the three -year tackling operation of Qingdao City, urban renewal, and urban construction in 2022. The starting point of the natural gas pipeline of Jiaozhou Bay is the State Pipeline Network Zhang Yingying Station, passing through Jiaozhou City and Chengyang District, entering the sea from the Women's Gushan Bridge to the west, landing from the sea and land pipe interface from Licun River to Haikou, and the city "three Horizontal high -pressure gas pipeline docking. The total length of the project is 72 kilometers, of which the bottom of the sea reaches 12 kilometers. The total gas transmission capacity is 3.6 billion cubic meters per year. It is an important energy basic supporting project and the project in our city. Coal -to -gas "project and large gas power generation project coordinated together to build a" clean, low -carbon, safe, and efficient "energy guarantee system to provide" dual carbon "strategic goals of our city to provide" full gas ", and for urban construction and development Provide a strong "energy engine".
