An Efficient Measure to Mitigate the Response of High-Pressure Gas Pipelines Crossing Potentially Unstable Slopes
High-pressure gas pipelines often cross potentially unstable slopes under static and/or seismic conditions. Consequently, their structural integrity may be detrimentally affected by Permanent Ground Displacements (PGDs) due to landslides, leading to pipe failures. Since pipeline rerouting is often unfeasible due to various techno-economic...

Offshore Pipelines and stability assessment of Submerged Slopes under Seismic Conditions

National Technical University of Athens
National Technical University of Athens
Depending on the prevailing bathymetrical and geotechnical conditions, the integrity of offshore pipelines is threatened by potential slope instabilities that occur at the seabed or at the bottom of lakes. In addition, submarine slides are more frequent in seismic regions. The instability of onshore slopes under seismic conditions is undoubtedly a...

Real-time remote monitoring and risk management of oil & gas facilities subjected to natural hazards
The term “natural hazard” is used to describe any natural pheno menon that might have a negative effect on humans and/or the environment. The natural hazards can be classified into two broad categorie s: geological and meteorological (e.g. landslides, volcanic eruptions, heavy storms, floods, droughts and high ambient temperatures). Furthermore, it...
