With basis in field experiences from several carcass axial failures in HT/HP unbonded flexible risers a comprehensive program was initiated to determine the root cause and develop a theoretical framework for prediction of the loads and mechanisms lea

This paper discusses the structural challenges associated with high axial temperature gradients and the corresponding internal cross section forces. A representative flexible pipe section designed for high operational temperature has been subject to

There are more than 3500 dynamic unbonded flexible risers in operation worldwide. In addition, there is a considerable number and kilometres of flexible flowlines and jumpers on the seabed. The average riser age is more than 10 years and a number of

During Statoil’s recent riser replacement project more than 30 used risers have been dissected onshore [1]. The main objective has been to reveal the root cause of carcass axial tearing failures. However, this also gave the opportunity to investiga

This paper presents a methodology for performing a lifetime assessment of flexible pipes applicable to re-qualification during the original design life and at life extension. A systematic approach is developed, providing flexible riser and flowline e

Recent failures of multi-layer pressure sheath risers have shown that the carcass may fail in the top termination due to excessive axial loads. This is a new failure mode for flexible risers, recently presented by the authors in more general terms. T

Statoil have experienced failures in a number of flexible risers due to collapse, overload, tearing and unspiraling of the carcass in pipe structures with multi-layer PVDF pressure barrier. The paper will discuss the carcass failure modes that are ch
