Influence of Stiffeners and Buckling Arrestors on the Behaviour of Offshore Pipelines under Bending


  • Federico Guarracino



Stiffeners, buckle arrestors, offshore pipelines, bending.


 On the basis of past experimental results and of a simple analytical formulation it is shown that the presence of stiffeners and buckling arrestors can substantially alter the strain and stress distribution in offshore pipelines under bending. A simple formula is provided to estimate such effects.
