Upheaval Buckling in Pipelines (Analytical)




The three days training programme gives an in-depth insight into the upheaval buckling design of pipeline system.

Who should attend :

  • Pipeline engineers
  • Marine engineers
  • Project engineers and managers
  • Engineers from other sectors of the oil and gas industry aspiring to develop this skill

The course takes the engineers through the concepts of upheaval buckling and step by step calculation process involved in upheaval buckling.

The course covers both SRA method and DNV-RP-F110 approach of upheaval buckling analysis.

The course is based on analytical method of calculationĀ  of propensity of upheaval buckling and its mitigation.

The areas covered are :

  • AssessmentĀ  of suitability of suitability of soil for mitigating upheaval buckling by undrained local failure check and undrained global failure checks
  • Calculation of soil and/or rock backfill cover height for mitigating upheaval buckling by global drained failure check.

The schedule of the course is as below.

Day 1

Theoretical Concepts of Upheaval Buckling in Pipelines

Day 2

Workshop involving step by step calculations of uplift propensity, soil and rock backfill cover

This includes calculation of :

  • Uplift force in pipeline
  • Undrained global and local failure checks of the soil to determine its suitability to mitigate UHB
  • Soil and rock cover calculations

Day 3

Hands on experience in Spectrum Pipelines software : Upheaval buckling module

  • The users will be given details of inputs to be entered into the software
  • Calculations of output by the user
  • Interpretation of results and how to report them

Question and Answer Session and conclusion

Note : This course is based on analytical methods. FE analysis is not involved. For upheaval buckling course based on FE analysis, refer to Advanced Upheaval Buckling Analysis (FE Based)
