Analysis and Calculation of Impact Resistance of Large LNG Tanks
Author of the article:Luo Dingming,Gu Yong,Zhang Xun,Zhang Cheng
Author's Workplace:China Petroleum Engineering & Construction Corp.Southwest Company
Key Words:LNG tanks; Impact from flying objects; Analysis and calculation
Abstract:

 The analysis of the impact of external objects on LNG tanks is an important and difficult problem in the design of large LNG tanks. This paper combines the impact dynamics with LUSAS finite element numerical simulation analysis and calculates through standard formula the local effect caused by foreign object on the top of20x104m3LNG pre-stressed tank, to verify the safety & reliability of the roof and provide guidance for the reliability analysis and calculation of similar tank roof safety.
