Dynamics of buried pipelines

International Journal of Soil Dynamics and Earthquake Engineering, 1985
Abstract Estimation of peak stresses in buried pipelines due to ground shaking is studied in this paper. Particular attention has been focused on the analysis of the stiffnesses of springs replacing the surrounding ground. It is shown here that these stiffnesses are functions of the wavelengths and frequencies of the seismic disturbance.

Cyclic Ratcheting Resistance of Buried Pipelines

Offshore Technology Conference, 2017
Abstract Upheaval buckling (UHB) is a common issue for high pressure and high temperature (HPHT) pipelines. The out-of-straightness (OOS) of the buried pipelines combined with the high axial compressive forces induced by the extreme operating conditions causes the pipeline to move upwards till the downward soil resistance is sufficient ...

Hierarchical Controller for Autonomous Tracking of Buried Oil and Gas Pipelines and Geotagging of Buried Pipeline Structure

2019 IEEE International Conference on Cybernetics and Intelligent Systems (CIS) and IEEE Conference on Robotics, Automation and Mechatronics (RAM), 2019
Oil, and gas pipeline network around the globe are highly complex and are exposed to extreme environmental conditions. Routine inspection and maintenance of these pipelines thus have high priority in the oil and gas operations. Pigging is one of the most promising internal pipeline inspection technique employed by the oil and gas industry, but the pre ...

Vulnerability of Buried Pipelines to Landslides

Volume 2: Pipeline Safety Management Systems; Project Management, Design, Construction and Environmental Issues; Strain Based Design; Risk and Reliability; Northern Offshore and Production Pipelines, 2016
The movement of a mass of rock, debris or earth down a slope is a landslide, which in the pipeline industry is often referred to as ground movement. Landslides continue to cause pipeline failures throughout the industry, sometimes as the singular cause of failure and in others cases as a contributing factor to failures (such as stress corrosion ...
