当地时间3月13日，由中国企业建设的柬埔寨戈公省（国公省）波东沙哥县2×450MW燃机联合循环电站核心设施——20万立方米液化天然气（LNG）低温储罐，在雨中完成气顶升。该储罐是柬埔寨历史上首座LNG储罐，建成后也将成为东南亚地区最大的LNG储罐。

On March 13th local time, the core facility of the 2×450MW gas turbine combined cycle power station in Bodongshaoguo County, Gokong Province (Koh Kong Province), which was constructed by Chinese enterprises, completed the gas lift operation in the rain. This storage tank is the first LNG storage tank in the history of Cambodia and, upon completion, it will also become the largest LNG storage tank in Southeast Asia.

当日上午7时48分，承建单位中国化学工程第六建设有限公司（简称六化建）的施工团队启动气顶升作业。《中国化工报》记者在现场看到，在4台风机的共同作用下，约850吨重的拱顶从地面缓缓升起，4小时后顺利到达罐顶。据悉，此次气顶升作业比原定工期提前了17天。

At 7:48 am on the same day, the construction team of the contracting company, China Chemical Engineering Sixth Construction Co., Ltd. (referred to as Six Chemical Construction), initiated the gas lifting operation. A reporter from China Chemical Industry Daily was on the scene and witnessed that under the joint action of 4 wind turbines, the approximately 850-ton dome slowly rose from the ground and successfully reached the top of the tank after 4 hours. It is reported that this gas lifting operation was completed 17 days ahead of the originally scheduled schedule.

气顶升是低温储罐工程中难度较大、风险较高的关键环节之一。六化建科技与数字化部技术人员胡勇介绍，气顶升作业依靠五大系统密切配合，即由24个T型架组成的平衡系统、由4台风机组成的动力系统、由钢板压条和铝箔布组成的密封系统、由尺子和U型压力计组成的测量系统和由对讲机组成的联络系统相互协作，才能顺利完成。

The gas lifting operation is one of the most challenging and risky key steps in the construction of low-temperature storage tanks. Hu Yong, a technician from the Technology and Digitalization Department of Six Chemical Construction Company, explained that the gas lifting operation relies on the close cooperation of five major systems, namely the balance system composed of 24 T-shaped frames, the power system consisting of 4 wind turbines, the sealing system made of steel plates and aluminum foil cloth, the measurement system including rulers and U-shaped pressure gauges, and the communication system with walkie-talkies, to be successfully completed.

项目经理魏洛东接受记者采访时表示：“本次气顶升非常顺利，没有出现应急预案中的偏重等问题；且经过与业内专家沟通，拱顶和抗压圈的契合度比较均匀，达到优质工程的标准。后续我们还将进行内罐施工、水压试验等工作。”

Project Manager Wei Luodong said in an interview with reporters: "The gas lifting operation was very smooth this time. No problems such as excessive weight as mentioned in the emergency plan occurred. Moreover, after communicating with industry experts, the fit between the dome and the pressure-resistant ring was relatively uniform, meeting the standards of a high-quality project. In the future, we will also carry out the construction of the inner tank and water pressure testing, etc."

据悉，该项目2025年5月开工，项目团队克服了雨季高温潮湿、工期紧张等各种困难，顺利完成各个节点任务。“优秀，非常优秀！”业主单位柬埔寨皇家集团项目现场经理俞进这样评价项目建设工作，“从目前的工作评估来看，六化建的各项工作非常出色。气顶升完成之后的焊接、安装工作同样重要，我也非常有信心项目能够早日投产达效。”

It is reported that the project started in May 2025. The project team overcame various difficulties such as high temperatures and humidity during the rainy season, as well as tight schedules, and successfully completed all the tasks at each stage. "Excellent, extremely excellent!" Yu Jin, the project site manager of the Royal Group of Cambodia, who is the owner unit, commented on the project construction work. "From the current work assessment, all the work of Sixi Construction is very outstanding. The welding and installation work after the gas lifting is also very important. I am very confident that the project can be put into production and achieve efficiency as soon as possible."

记者了解到，2×450MW燃机联合循环电站建设对柬埔寨意义重大，电站建成后将为柬埔寨提供约20%的电力。该电站使用天然气发电，因此LNG储罐的建设是关键。“这个储罐就相当于一个大型的家用煤气储罐，把从其他地方运送过来的LNG储存起来，再往外输送进行发电或作他用。” 魏洛东向记者解释。

The reporter learned that the construction of the 2×450MW gas turbine combined cycle power station is of great significance to Cambodia. Once the power station is completed, it will provide approximately 20% of the electricity for Cambodia. The power station generates electricity using natural gas, so the construction of the LNG storage tank is crucial. "This storage tank is equivalent to a large household gas storage tank. It stores the LNG transported from other places and then transports it for power generation or other uses," Wei Luodong explained to the reporter.

而谈及后续合作，俞进表示，中国是基建强国，无论是技术、质量和工期保证还是成本控制，中国企业都是可靠的选择。

When it comes to future cooperation, Yu Jin stated that China is a powerhouse in infrastructure construction. In terms of technology, quality, schedule guarantee, and cost control, Chinese enterprises are reliable choices.
