Xinhua News Agency, Macau, March 28 (Reporters Liu Gang and Li Hanfang) The reporter learned from Macau City Gas Co., Ltd. on the 28th that the Taipa-Macau Peninsula Natural Gas Cross-sea Pipeline invested and constructed by the company has successfully passed through the sea recently, and will soon organize auxiliary projects. Construction, to realize the transmission of natural gas from Taipa to the Macau Peninsula in the middle of the year.
By then, the main natural gas pipeline in Macao will be fully connected, and the natural gas pipeline network in Zhuhai and Macao will be fully connected, which will fundamentally solve the key and difficult problems in the application of natural gas in Macao, effectively guarantee the long-term, safe and stable supply of natural gas in Macao, and lay a solid foundation for the realization of multiple gas sources in the peninsula. Solid foundation.
Macau City Gas Co., Ltd. is jointly established by Nam Kwong Petrochemical Co., Ltd., Sinopec Great Wall Gas and Macau New Energy.
According to Tang Zhaohui, general manager of Nam Kwong Petroleum, the project is a key project of the SAR government's 2022 policy address.
After full consideration of the geological conditions and construction environment of Macao, and repeated scientific demonstrations and comparisons, the trenchless directional drilling crossing technology was finally selected.
The entry and excavation points of the cross-sea pipeline are located on the south side of Sai Wan Lake on the Macau Peninsula and the Taipa Seaside Recreation Area, with a total length of about 2 kilometers.
The deepest crossing point of the pipeline reaches 58 meters below sea level, which is the longest and most difficult directional drilling crossing project in Macau so far.
Tang Zhaohui said that in the construction process, in order to avoid noise disturbing the people, a special low-noise electric drilling rig was specially customized to replace the diesel drilling rig, each equipment was equipped with a soundproof cover, and a heightened and thickened sound insulation board was set up in the construction area, and the construction process was carried out in real time. Noise monitoring and control; In order to reduce the occupation of green space and the migration of trees, scientifically optimize the construction plan, the pipeline is connected in nine sections on site, which minimizes the construction land area.
Fu Jianguo, Chairman of Nam Kwong Group, said during the on-site investigation of the project that the construction should be carefully organized to ensure the quality and safety of the project, so that the general public can use low-carbon, safe, economical and stable natural gas as soon as possible, and actively help Macao to optimize the energy consumption structure and cost saving.
