A vision of the digital twins of the subsea pipelines is provided in this paper, with a coverage
of the current applications and the challenges of the digital twins in the design, construction …

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 …

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 …

The failure of corroded ultra-high-strength steel (X100 and X120) pipelines under combined
axial loads and internal pressure is investigated numerically by finite element analyses, and …

A comprehensive literature review in seismic analysis of free-spanning offshore pipelines
(FSOPs) reveals that two critical aspects, ie the offshore earthquake motions and various …

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

This study comprehensively evaluates the thermal upheaval buckling of a functionally
graded porous (FGP) pipeline laid on an arched concave seabed. The FGP pipeline is …

The present research work focuses on obtaining the critical buckling temperature (ΔT cri) of
an offshore pipeline model from one-dimensional and three-dimensional finite element …

Subsea pipelines composed primarily of carbon steel are susceptible to upheaval buckling
in the presence of elevated temperatures and pressures. The thermal performance of …

Subsea pipelines are usually buried by shallow soils to avoid environmental damages in
terms of water scouring, corrections and ocean sea creatures attacking etc [1, 2]. However, it …
