Upheaval Buckling Calculation for Onshore Buried Pipeline Systems

Objective

The objective of this course is to equip pipeline design and integrity engineers with a thorough understanding of upheaval buckling behavior in buried pipelines, enabling them to perform accurate calculations, identify potential risks, and implement effective mitigation strategies. The course aims to build both conceptual clarity and practical competence in analyzing the effects of thermal expansion, soil resistance, and pipeline-soil interaction under different operating conditions. By the end of the program, participants will be able to confidently assess the likelihood of upheaval buckling, interpret analysis results, and apply appropriate design measures in compliance with international codes and standards.

Subject Description

This specialized course provides a comprehensive overview of the mechanics, assessment methods, and design principles associated with upheaval buckling in onshore buried pipeline systems. It covers the causes, influencing parameters, and analytical approaches used to predict and control buckling phenomena arising due to thermal and pressure-induced expansion. Participants will learn how to perform step-by-step calculations, evaluate the influence of soil cover, friction, and restraint, and apply both analytical and numerical approaches to real-world pipeline scenarios. The course further explores industry-recommended practices, mitigation techniques such as trench design and hold-down systems, and practical case studies to ensure engineers can directly apply the knowledge in field and design projects.
