Sandwich pipe with high-pressure resistance and the adequate insulation performance is a
potential deepwater offshore oil and gas development solution. This paper establishes a two …

A cohesive zone model based reliability analysis for a sandwich pipe (SP) is presented in
this paper. The collapse or burst strength of SP is predicted by a cohesive zone model …

In this study, we present an analytical method for multilayered pipes with temperature-
dependent (TD) properties under non-uniform pressure and thermal load based on …

The buckling propagation in deep-sea service sandwich pipes is prone to occur under the
influence of third-party loads. Therefore, it is crucial to determine the carrying capacity of the …

Sandwich pipe consisting of inner and outer filament-wound (FW) skins bonded to a core
material is a lightweight alternative to single-wall or pipe-in-pipe systems. In operation the …

Sandwich pipes (SPs) with adequate strength performance and thermal insulation capacity
have become an attractive choice for oil and gas transportation in deep water. The SP has a …

Sandwich pipe with cement composite core is capable of submarine pipelines application in
deepwater harsh environment due to its superior structural resistance and energy …

Integral buckle arrestors are regarded as the most effective arresting devices and can be
perfectly adapted to innovative sandwich pipes. In the present study, hyperbaric chamber …

Non-dispersive underwater concrete (NDC) is extensively used in underwater engineering.
This study firstly proposed a novel low-porosity NDC. Secondly, the effect of slenderness …

It is crucial to reveal the dent deformation mechanism of the sandwich pipe (SP) for the dent
evaluation of damaged offshore SPs. This study aimed to explore the difference in dent …
