... Abstract Lateral buckling mitigation design for HPHT pipe-in-pipe system is technically challenging and at times the reliability of proven buckling mitigation options may come into severe technical scrutiny for some HPHT pipe in pipe systems on the undulating seabed. The Residual Curvature...

... is calibrated using the recorded 2012 MBES survey in-service pipeline lateral buckling profiles. The calibrated FE model generates axial stress ranges at critical locations (buckle crown); these stress ranges are subsequently used to perform fatigue analyses. The estimated fatigue damage is used to forecast...

... and qualified methods and materials and ensured integrity for the 25 year design life. This paper outlines the approach to thermal expansion management through engineered lateral buckles. The selection of buoyancy sections in preference to sleeper arrangements, which have been popular in the past...

... Abstract This paper reviews the requirements for monitoring pipelines susceptible to lateral buckling and walking, focusing specifically on the methods available for surveying such pipelines, the accuracy required and the subsequent review and analysis of system integrity, which has also...

... to address one of the key design challenges for pipelines - buckling due to the compressive forces created by internal pressure and temperature - by supporting and guiding a design approach that deliberately encourages pipelines to buckle, but in a controlled way. By controlled initiation of lateral buckles...

... on a number of deepwater developments and discusses the issues with these control methods, including the increased potential for route-curve pullout. The paper also investigates the complex interaction between pipeline walking and lateral buckling. It is known that lateral buckles along a pipeline can...

... Abstract This paper addresses the influence of pipe-soil interaction on the design of pipelines susceptible to lateral buckling and pipeline-walking. The pipe-soil response is the largest uncertainty in the design of such systems, and has a significant influence on the structural limit states...

...., fax 01-972-952-9435. Abstract This paper addresses lateral pipe-soil interaction behaviour at the large displacements that occur with lateral buckling of a pipeline. Force-displacement response models were developed by the SAFBUCK JIP to replace the use of Coulomb friction approximations, which...

...., fax 01-972-952-9435. Abstract This paper reviews various methods available for surveying and monitoring the condition of laterally buckled flowlines in deepwater, with sufficient accuracy to meet integrity management requirements. Subsea pipelines are increasingly being required to operate at higher...
