LNG, Liquefied natural gas, Finite element method
Finite element analysis (FEA) of the hose assembly used for transportation of Liquefied natural gas (LNG) has become a powerful tool in predicting the deformation and stress distributions. FEA helps in analyzing the model and optimizing the design in hostile environment. In the present work, computations are made to predict the maximum stresses caused due to structural and thermal effects in the LNG transportation. The analysis leads to the selection of the appropriate materials to be used and to the identification of both the most critical measurements and parameters. Most engineering design methods are deterministic, but in reality, many engineering systems are stochastic in nature where probability assessments of the results are required. This probabilistic design analysis assumes the probability distribution of design parameters, instead of the mean values. These factors helps in designing a system which takes into account the safety, quality and the cost for the system. In this present work, structural and thermal analyses of the system are carried out to find out the maximum stresses in the design and a probabilistic analysis is made to determine the critical design parameters responsible to optimize the design
