Abstract We studied the optimization method to reduce the amount of resin rope that used to fill the gap between the LNG tank and insulation panels while complying with the flatness criteria of the insulation panels.
The space between the thermal insulation panels and LNG tank hull should be reduced to minimize the use of resin rope. In this study, the corrugation of the inner side of the hull is measured, and the offset table of the corrugation is used to calculate the deformation of the LNG tank hull. To solve the optimization problem, an objective function with constraints is mathematically formulated and solved by using the genetic algorithm.
To check the applicability of the proposed method, we simulated thermal insulation panel installation and compared with an existing program. The results show that the proposed method can be effectively used for installation of the thermal insulation panels of the LNG tank.
