日前，四建公司承建的中海油江苏滨海一期扩建LNG项目一标段5#储罐开始进水试验，实现又一重要施工节点目标，这标志着全球单罐容量最大的27万立方米LNG储罐主体工程建设基本完成，得到业主和总包单位的高度认可，也为该罐明年春节前实现机械完工奠定坚实基础。

本次LNG储罐水压试验计划40天内完成，上水高度约26米，用水量近18万立方米，水压试验期间要完成注水、排水、储罐清洗、沉降观测、倾斜观测等工作。此次储罐上水的顺利进行，为后续储罐内外防腐、附件安装等工作的开展打下良好的基础，对推动整个项目建设工期具有重要意义。

Recently, the 5 # storage tank of the first section of the Jiangsu Binhai Phase I LNG expansion project of China National Offshore Oil Corporation (CNOOC) undertaken by the Fourth Construction Company began water inflow testing, achieving another important construction milestone goal. This marks the basic completion of the main project of the world's largest single tank capacity of 270000 cubic meters of LNG storage tank, which has been highly recognized by the owner and general contracting unit. It also lays a solid foundation for the mechanical completion of the tank before next year's Spring Festival.

The LNG storage tank hydraulic test is planned to be completed within 40 days, with a water filling height of about 26 meters and a water consumption of nearly 180000 cubic meters. During the hydraulic test, water injection, drainage, tank cleaning, settlement observation, tilt observation, and other work must be completed. The smooth progress of water filling on the storage tank this time has laid a good foundation for the subsequent anti-corrosion and accessory installation work inside and outside the tank, and is of great significance for promoting the entire project construction period.
