This paper consists of a literature review on the latest research progress about the lateral buckling of submarine pipelines under high temperature (HT) and high pressure (HP). First, the main general assumptions and simplifications made in the context of pipe lateral buckling are summarized in order to better understand the practical behavior of submarine pipelines. The governing equations of pipelines under uniaxial compression are then derived. Next, the controversial but widely deployed concept of effective axial force under complex sea environment is introduced. Influential parameters including initial imperfections, pipe-seabed interactions and residual stresses are elaborated and discussed. Furthermore, numerical simulation methods and experimental tests dealing with the lateral buckling of pipelines are presented as well. Controlled methods which are practically used for buckle initiation are described. This paper also reveals the remaining challenges and new tendencies, such as the use of data-driven methods for the smart prediction of pipe buckling. Finally, a specific case study is numerically conducted. It is found that the effect of axial friction variation can be generally ignored in practical calculations. This paper may provide a guidance for the design and research on pipelines in the future.
