In this study, according to the nonlinear von-Kármán assumption and Euler-Bernoulli beam
theory, a mathematical model is proposed to simulate upheaval buckling of lined subsea …

Vulnerability of subsea high pressure/high temperature (HP/HT) pipelines to seismic actions
is studied numerically. Unlike most of the existing researches on buried or trenched …

Sandwich pipe is one of the most promising subsea pipelines for oil and gas transportation
in deep waters due to its high-strength performance and thermal insulation. The gradient of …

Cylindrical shell structures are ubiquitous and essential supporting structures in various
engineering applications. The aim of this research work is to provide a comprehensive …

Horizontal well is one of the main measures to improve oil and gas production capacity.
However, with the extension of horizontal section, the risk of pipe string buckling will be …

This research investigates the collapse mechanisms and crossover pressure capacity of
carbon fiber-reinforced polymer (CFRP) buckle arrestors in subsea pipelines. A nonlinear …

Submarine pipeline is used for transporting oil from wells to resource storage facilities. The
oil inside the pipeline is heated and pressured for long-distance transportation, making the …

Submarine pipelines can utilize sleepers to control global buckling location, which mitigates
potential risks under high temperature and pressure. However, pipelines with sleepers …

This study deals with the upheaval thermal buckling of functionally graded subsea pipeline
subjected to thermal loadings. The temperature-dependent material properties of the …

The nonlinear pipe-soil interaction model and the initial imperfections are predominantly
factors that affect the lateral buckling behaviour of subsea pipelines with a high-temperature …
