DOI: 10.1016/j.marstruc.2018.03.010
Abstract: Buried subsea pipelines under high temperature conditions tend to relieve their axial compressive force by forming localised upheaval buckles. This phenomenon is traditionally studied as a kind of imperfect column buckling problem. We study upheaval… read more here.

DOI: 10.1016/j.oceaneng.2017.09.035
Abstract: Abstract Unburied subsea pipelines designed to operate under high temperature and high pressure (HT/HP) conditions tend to relieve their axial compressive force by forming lateral buckles. Uncontrolled lateral buckling can lead to pipeline failure, such… read more here.

DOI: 10.1080/17445302.2020.1735834
Abstract: ABSTRACT Failure threats in subsea pipelines are hard to inspect, but parameters influencing them are easier to observe. Hence, nowadays, Bayesian network models became more relevant, as the model can be updated with the sparse… read more here.

DOI: 10.2118/199353-pa
Abstract: A good pipeline design must ensure that the heat loss is small enough for flow assurance despite unfavorable hydrate and wax depositions. The objective of this study is to experimentally verify a formula for the… read more here.
