This is a blog on residual curvature installation for subsea pipelines. Martin Teigen and Malik Ibrahim have run several research projects on residual curvature installation to learn more about what this method can offer to subsea pipeline design. This blog aims at addressing some of these findings, and getting in touch with the engineering community about the residual curvature method.

Please note that this blog is not affiliated with Equinor, which is the patent owner of the residual curvature method.

We have developed the following technical papers on RCM:

  • OMAE2020-18261 Analytical Formulae for The Lateral Buckling Behaviour of Pipelines Installed with Residual Curvature.
  • IAFMI2017 Introduction to the Residual Curvature Method (RCM) for Subsea Pipeline Lateral Buckling Control.
  • OMAE2017-61541 Validation of Residual Curvature Installation for Lateral Buckling Management using Structural Reliability Analysis.
  • OMAE2015-41848 Investigation of the Behaviour of the Lateral Buckling Control Method – Reel-Lay Induced Imperfection.
