Abstract The current study is a simplification of related components of large floating roof tank and modeling for three dimensional temperature field of large floating roof tank. The heat transfer involves its transfer between the hot fluid in the oil tank, between the hot fluid and the tank wall and between the tank wall and the external environment. The mathematical model of heat transfer and flow of oil in the tank simulates the temperature field of oil in tank. Oil temperature field of large floating roof tank is obtained by numerical simulation, map the curve of central temperature dynamics with time and analyze axial and radial temperature of storage tank. It determines the distribution of low temperature storage tank location based on the thickness of the reservoir temperature. Finally, it compared the calculated results and the field test data; eventually validated the calculated results based on the experimental results.

Finite element method has been used to analysis the stress of inner pipes of low temperature storage tank for LNG caused by temperature, pressure and weight. Filling liquid state, storing liquid state and unloading liquid state are considered in this paper. The results show that the stress of the top pipes would be the largest under filling liquid state which is only little larger than storing liquid state. The stress of the bottom pipes would be the largest under storing liquid state. The deformation of the inner container of the tank would influence the stress distribution. Choosing a flexible structure as designing the bottom pipes is reasonable.
