On the flexural structural behaviour of flexible pipes, umbilicals and marine cables

Witz, J.A. / Tan, Z.

AbstractA general analytical model to predict the flexural structural behaviour of multiple layer flexible structures such as flexible pipes, umbilicals and amrine cables is presented. The flexural response of these structures is shown to be dominated by relative movement between component layers once a critical curvature has been exceeded. This slip mechanism leads to a hysteretic bending moment-curvature relationship for generic flexible structures. Bending tests have been carried out on three representative specimens consisting of a marine cable, an umbilical and a flexible pipe. Satisfactory agreement between theory and experiment is demonstrated.
