Connecticity!Jiaozhou Bay Sea Underwater Gas Pipeline Engineering Section Pipelines all enter the sea

Qingdao Daily/Guanhai News News from the high altitude overlooking Jiaozhou Bay Underwater Gas Pipeline Project is located in Shuangu, Shuangbu, Chengyang District. The pipeline that is about to enter the sea is like a long dragon.

At 10:48 am on the morning of September 6th, with the order of the person in charge at the scene, the last group of the leading pipe section of the natural gas pipeline section of Jiaozhou Bay to complete the welding in the prefabricated field of Shuangbu, and it was laid at the venue by laying through the venue. The transportation track slowly slid down the slope and began to enter the sea. 47 minutes later, all 493 meters of long tube sections entered Jiaozhou Bay, and under the buoyancy of the green buoy, a tugboat was dragged to the designated work location. It will be connected to the end of the 21 groups of pipelines entering the sea in the early stage. East and west runs through Jiaozhou Bay to build an important energy guarantee system in Qingdao.

"This also marks the basically end of the construction of the entire sea." Huang Cheng, the project manager of the China Petroleum Pipeline Bureau Engineering Co., Ltd., Qingdao Bay Underwater Pipeline Engineering Project, said that since May 2, Shuangbu Floating Drag Quan prefabricated venue was fully completed and launched after being fully completed and launched. , Jiaozhou Bay Sea Underwater Pipeline Project has set off the "Acceleration Key": On May 17, after the pipeline was just entered, the pipeline section was officially fired and welded in the floating dragging site; The land and sea directional drill rods and floats are successfully connected. After the "exploration, wearing, and" three -in -one operation, the land -sea directional diamond -oriented hole construction of the domestic city is successful. ", Became the" base point "of precise connection operations through construction and sea -floating drag sections; on June 20, with the successful drag of the first section of the sea, the sea section was dragged down to the sea to work.

"As the largest part of the construction weight in the construction of the sea area, in the 128 days and nights, the participating staff of the project department faced the 40 -degree heat of the heat and passed through the rainwater of the knee. , Safe and efficiently completing the floating of the 22 -segment pipeline to work into the sea. "

According to Bi Hongbo, deputy general manager of Qingdao Energy China Resources Gas Co., Ltd. and the manager of Jiaozhou Bay Underwater Pipeline Engineering Project Department, it is an important gas source guarantee for the work of "coal -to -gas" in Qingdao City to heating coal -fired boiler "coal -to -gas boiler" The project was included in the three -year tackling operation of the city's work, urban renewal and urban construction in 2022. The reporter learned that the starting point of the natural gas pipeline under the Underwater Bay of Jiaozhou Bay is the State Pipe Network Zhang Ying Yingying Station, passing through Jiaozhou City and Chengyang District, entering the sea from the Women's Gushan Bridge to the west. The "three horizontal four vertical" secondary high -voltage gas pipelines are connected to the urban area, and it extends south to Huadian Qingdao Power Plant. 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 in our city. The pipeline is the longest urban gas pipeline in China. It is also the first natural gas pipeline that is laid by the land -to -sea "directional diamond" process to use the land -to -sea "directional drill" process. At the same time, the pipeline is closely combined with urban construction. It will cross large rivers, 16 small rivers and ditches; 10 highways, 1 national highway, 65 municipal and other level roads; 5 railways, 4 subway places, 4 subway places , 2 bridges.

"The land section of the entire natural gas pipeline project of Jiaozhou Bay is 60 kilometers, and it has been completed for 24 kilometers. In addition to the construction of the sea section, the overall project has been completed by half. The project will be put into production during the year After completion, it will cooperate with the Dongjiakou LNG terminal project, the global "coal -to -gas" project, and the large -scale gas power generation project. The guarantee system provides "dual carbon" strategic goals to provide "full gas" and provides a strong "energy engine" for urban construction and development.
