Description
Advanced FE analysis is more detailed compared to analytical FE analysis. This five days course offers a more in-depth assessment of upheaval buckling in pipelines using Finite Element Analysis.
Who should attend :
- It is recommended that engineers who have already attended the Analytical Upheaval Buckling Corse should attend this course for better grasp of the subject.
- Engineers who have experience in FE analysis. (Engineers who have attended the Application of FE methods in Pipeline Engineering will benefit most from this course)
- Project managers and project managers working in the pipeline industry
Course schedule
Day 1
- Theoretical concepts of Upheaval Buckling in pipelines.
Day2
- Out-of-straightness (OOS) survey of pipeline route, data collection and processing
- Survey Data smoothing
Day 3
Sand Soil
- Building Abaqus Global Model of pipeline
- Putting the pipeline on undulating seabed
- Extraction of uplift force from the FE model and translating it into soil/rock cover height
- Running global model to examine if the soil/rock backfill cover height is sufficient
Day 4
Special treatment of clay soil of low undrained shear strength
Handling soil slurry in pipeline trenches and how to incorporate slurry layer thickness in Global model
Day 5
Importance of time in performing UHB analysis based on OOS survey result
Reporting of results suitable for use by rock/soil backfill contractor
