Global buckling

This 2-day training course gives an introduction to design philosophy of DNV-RP-F110, how it complements DNV-ST-F101 and specific requirements for global buckling scenarios of HT/HP pipelines.

The Recommended Practice DNV-RP-F110 gives guidance on how to design an exposed pipeline to buckle in a controlled manner in order to release the compressive axial effective forces caused by high temperature and pressure. Further, it gives guidance on how to design a trenched pipeline to stay in place, exposed to high compressive effective axial forces. The principles have been developed in a joint industry project involving leading oil companies and consultants.

Course description

The course will give an introduction to the design philosophy of the DNV-RP-F110, how it complements to the DNV-ST-F101, and gives specific requirements for global buckling scenarios of HT/HP pipelines.

Learning objective

Understand how to design new and assess existing pipelines, with respect to global buckling of HP/HT pipelines.

• The causes the compressive forces
• The relevant failure modes for global buckling
• Limitation of loads
• Design solution for both exposed and buried pipelines.

Target group

Pipeline engineers that will perform design activities, or want an insight in design challenges of HP/HT pipelines.
