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.

Dynamic Analysis of Umbilical Cable Under Interference With Riser
Ships and Offshore Structures, 2018In consideration of the bend moment and torque, the lumped mass method was derived. Based on the lumped mass method, the umbilical cable was discretised into a lumped mass model and the interferenc...

Three-Dimensional Dynamic Behavior of the Flexible Umbilical Cable System
Applied Mechanics and Materials, 2013 We extend an idea of the modeling flexible umbilical cable using a nonlinear finite element method to three-dimensional space. The umbilical cable is assembled by Reissners geometrically exact beam elements, which take account of the geometric nonlinearities of large rotation and displacement, and effects of axial load, transverse shear, torsion and ...

A Finite-Element Approach for Calculating Electrical Parameters of Umbilical Cables
IEEE Transactions on Power Delivery, 2009This 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.

On the Motions of the Underwater Remotely Operated Vehicle With the Umbilical Cable Effect
Ocean Engineering, 2007Abstract In this paper, a hydrodynamic model is developed to simulate the six degrees of freedom motions of the underwater remotely operated vehicle (ROV) including the umbilical cable effect. The corresponding hydrodynamic forces on the underwater vehicle are obtained by the planar motion mechanism test technique.

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.

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.

Cabling umbilical and array layout
2013This chapter discusses the case of dynamic cables and subsea connectors for which the design requirements and specifications posed by marine energy applications are distinctly different from the ones typically applied in the offshore industry. Bespoke solutions are needed in this case as the design of the connection is largely dependent on the device ...
