大型LNG储罐罐顶预制及顶升工艺

The Technics of Fabrication and Air Raising of Large LNG Tank Roof

结合目前中国海油已建的LNG储罐项目，阐述了储罐建造的一般流程，指出了其中的建造难点并就LNG储罐罐顶预制及顶升的施工难点进行了较为细致的研究，提出了解决方法。

The fabrication of LNG tank as a part of the whole LNG receiving station is very important. The air raising is one of the difficult techniques in the tank fabrication. Based on the projects of China Offshore Oil Corporation, the general flow chart of LNG tank fabrication is expatiated in this paper. The difficulties in the fabrication is brought forward and the solutions are given through the research.
