A Finite Element approach for calculating electrical parameters of umbilical cables
IEEE Transactions on Power Delivery, 2010 This paper presents a systematic approach for calculating electrical per-unit-length parameters of signal cables by the Finite Element Method. The associated software (UFIELD) has been specifically adapted to umbilical cables used in offshore control applications.

A nonlinear formulation for the axisymmetric response of umbilical cables and flexible pipes
Applied Ocean Research, 2002Abstract This paper presents formulations and a solution for the response of umbilical cables and flexible pipes subjected to monotonic loading of tension, torque, internal and external pressures. The homogeneous and helical wound layers are, respectively, described by Lame's and Clebsch–Kirchhoff's formulations hence yielding nonlinear algebraic ...

Umbilical cable recovery load analysis
China Ocean Engineering, 2013Umbilical cable is a kind of integrated subsea cable widely used in the exploration and exploitation of oil and gas field. The severe ocean environment makes great challenges to umbilical maintenance and repair work. Damaged umbilical is usually recovered for the regular operation of the offshore production system.

Rotary bending of marine cables and umbilicals
Engineering Structures, 1995The stress analysis of a marine cable or umbilical in a rotary bending test rig is presented. It is shown that the finite length of the test sample and the terminations have a significant influence on the stresses in the umbilical which is taken into consideration in determining the cyclic stress distribution in the helical components.

An Integrated Environment for Design and Analysis of Umbilical Cables
Volume 5A: Pipelines, Risers, and Subsea Systems, 2017The design of an umbilical cable begins with the definition of the operational functions it must implement and the environmental conditions to that it will be subjected to. Those functions suggest the components that it must have, usually chosen from a pre-defined set.
