Abstract: Pipelines tend to buckle laterally under thermal expansion. In existing analytical solutions by Kerr and Hobbs, it is assumed that the seabed resistance q0 to lateral pipe movements is constant in magnitude and opposite ...

Abstract: Abstract. The stress concentration factor (SCF) for a hotspot at the root of a pipe girth weld due to high–low misalignment offset (hi/lo) is used in fatigue and fracture assessments, since some such offset is inevitable ...

Abstract: Although it has long been recognized that vortex-induced vibrations of subsea pipeline spans involve nonlinear and inelastic behavior, the current practice to assess such spans for fatigue and ultimate loading conditions ...

Abstract: Helical strakes can suppress vortex-induced vibrations (VIVs) in pipelines spans and risers. Pure in-line (IL) VIV is more of a concern for pipelines than for risers. To make it possible to assess the effectiveness of ...
