Local Stress Assessment of Flexible Unbonded Pipes Using FEA

Detailed stress analysis of unbonded flexible pipes has always been a challenging exercise which requires significant amount of computational resources and state of the art knowledge of flexible pipe modelling techniques. Lloyd’s Register EMEA and Brunel University have embarked on the development of a model which captures the response of the individual unbonded layers of flexible pipes using the ABAQUS finite element package employing 3D...
