The thermal expansion analysis is important in submarine pipeline design and research. A new thermal expansion analysis method of submarine pipe-in-pipe is proposed in this paper based on the shear lag theory. The axial force distribution and the thermal expansion displacement of submarine pipe-in-pipe can be calculated by this method. The analysis method is simple and convenient but with detailed results. It can be used for the thermal expansion analysis of submarine pipe-in-pipe.
