Kellogg has been for years actively involved in LNG industries. Publish- ing this paper ought to compliment Kellogg's effort in this field and also provide answers for our own future applications.

Description : By applying the method of superposition, this paper is to analyze the piping reactions due to introducing cold LNG into hot piping system. On one hand, this system is simulated based upon ther~l flexibility analysis - regarding the face of LNG flow as the point of temperature break. On the ether hand, the same piping system is modeled dynamically. Imposing the thermal loads at the face of LNG flow would produce a set of dynamic responses to the model. Then matching the common parameters such as internal stresses, displacements, loads upon constraints, etc., will/.r~~ set of outputs which should give the effects due ~o the ~~
