[Haichuan Overseas Engineering] Chinese company completes gas jacking of Cambodia’s first LNG storage tank

Thread Content

Cambodia’s first LNG storage tank was lifted using gas pressure. On March 13 local time, the 200,000 cubic meter low-temperature LNG storage tank, which is a key component of the 2×450MW gas turbine combined cycle power plant in Pothon Chak District, Stung Treng Province, Cambodia and built by Chinese companies, was lifted using gas pressure in spite of the rain. This storage tank is the first LNG storage tank in Cambodia’s history, and upon completion it will also become the largest LNG storage tank in Southeast Asia. At 7:48 a.m. that day, the construction team from the contractor China National Chemical Engineering Corporation Sixth Construction Co., Ltd. (abbreviated as NCCEC Sixth Construction) began the pneumatic jacking operation. A reporter from China Chemical Industry News witnessed at the scene that, with the combined effort of the 4 fans, an arch weighing about 850 tons was slowly lifted from the ground and successfully reached the top of the tank after 4 hours. It is reported that this pneumatic jacking operation was completed 17 days ahead of the originally scheduled deadline. Gas lift is one of the key processes in low-temperature storage tank projects that presents significant challenges and high risks. Hu Yong, a technician from the Technology and Digitalization Department of Liuhua Jianke, explained to reporters that air jacking operations can be carried out successfully only through the close coordination of five systems: a balance system consisting of 24 T-shaped frames, a power system made up of 4 fans, a sealing system composed of steel plates and aluminum foil, a measurement system using rulers and U-type manometers, and a communication system based on walkie-talkies. Project manager Wei Luodong said in an interview with reporters, “This pneumatic jacking process went very smoothly, without any issues such as excessive pressure that were mentioned in the emergency plan.” ； Furthermore, after consulting industry experts, it was found that the fit between the vault and the compression ring is quite uniform, meeting the standards of high-quality projects. Going forward, we will also carry out work such as the construction of the inner tank and hydrostatic testing. ” It is reported that the project commenced in May 2025, and the project team overcame various challenges such as the hot and humid weather during the rainy season and a tight schedule, successfully completing all the scheduled tasks. “Excellent, absolutely excellent! ”Yu Jin, the project site manager of the owner’s company, the Royal Group of Cambodia, commented on the construction work as follows: \"Based on the current assessment of the work, Liu Hua Jian has performed exceptionally well in all aspects of its tasks.\" Welding and installation work after the pneumatic lifting are equally important, and I am very confident that the project will be put into operation and start generating benefits at an early date. ” The reporter learned that the construction of a 2×450MW gas turbine combined cycle power plant is of great significance to Cambodia; once completed, the plant will supply about 20% of Cambodia’s electricity needs. The power plant generates electricity using natural gas, so the construction of LNG storage tanks is crucial.
