摘要：

Evaluating the fatigue life of a flexible riser requires several dynamic problems to be solved, considering a consistent representation of all environmental loads imposed to the structure. For each load case the stress field over the distinct concentric layers has to be determined. Accordingly, slip between adjacent layers must be considered as the resulting wear may reduce the section of the armour wires. This paper presents a design-oriented simplified methodology to assess the fatigue life of flexible risers, directly applicable in preliminary and early design stages.
