Structural and thermal analysis of the flange used in connection with hose for the transportation of LNG was computationally simulated by the method of finite element and probabilistically evaluated in view of the several uncertainties in the performance parameters. The distribution function and sensitivity factors for the maximum stresses were found out. The effect of various random variables including geometry, structural/thermal properties etc on the maximum stresses were studied probabilistically. These results were useful to identify the most critical random variable in order to optimize the design well before it is introduced in the market. This reduces the manufacturing cost of the product
