Abstract

A novel method of controlling lateral buckling using continuous pre-deformation of the pipeline is studied. Analytical and numerical modelling carried out in this research proves that the pre-deformed pipeline had significant lower axial stiffness compared to a straight pipeline. Pre-deformed pipeline is also robust and is shown not to be affected by geometric imperfections and pipe-soil interactions. This shows that the pre-deformed pipeline can be designed to operate at a high level of HPHT loading without the requirement of special structures installed on the seabed to control the initiation of lateral buckling and still maintain acceptable levels of axial strains.
