Pipe-Soil Interaction on a Clay Seabed
Subsea pipelines form an integral part of the infrastructure associated with offshore oil and gas developments. These pipelines fulfill a range of functions from linking extraction wells to other subsea infrastructure to transporting products onshore, or to a central processing facility. Ancillary …

Modeling the Behavior of Smart Oil Well Cements and Offshore Pipe-Soil Interaction in Very Soft Soil
… gas production infrastructures from borehole to pipelines. Rheology properties and hardening characteristics are some of the important parameters for cementing slurry during installation. Also over the last decade, health monitoring of the plugging material during service life became more …

FSI Methodology for Analyzing VIV on Subsea Pipeline Free Spans with Practical Boundary Conditions
… for free span stability of submarine pipelines based on fatigue analysis. A general assumption in performing vortex-induced vibration (VIV) analysis of pipeline free spans is that both ends of the free span are fixed and/or pinned in order to simplify computational simulations; …

Computational fluid dynamics modelling of pipeline on-bottom stability.
Subsea pipelines are subjected to wave and steady current loads which cause pipeline stability problems. Current knowledge and understanding on the pipeline on-bottom stability is based on the research programmes from the 1980s such as the Pipeline Stability Design Project (PIPESTAB) and American …

Landslide-pipeline interaction for onshore slopes in silty sand
Onshore oil and gas pipelines are often routed through hazardous terrain owing to the need to traverse large distances and inevitably crosses large slopes and river valleys. A type of linear critical infrastructure, pipelines must be designed to withstand the soil forces created by landslides, …

Experimental and numerical investigations to assess the behaviour of a buried pipeline in areas with high geological instability
… such as landslides, fault movements, soil liquefaction which may be caused by seismic activity are one of the most dangerous phenomena that can involve buried pipelines, e.g. for oil and gas transportation, or water and sewage. This aspect is currently an important part of research and …
