Prediction of the temperature distribution of partially submersed umbilical cables [PDF]
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2012 The objective of this work is to predict the temperature distribution of partially submersed umbilical cables under different operating and environmental conditions. The commercial code Fluent® was used to simulate the heat transfer and the air fluid flow of part of a vertical umbilical cable near the air-water interface.

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 ...

Study Simulation of Umbilical Cable for Underwater Vehicle [PDF]
Bulletin of the Polytechnic Institute of Iași. Machine constructions Section, 2021 Abstract This paper presents a series of analyses regarding the tethered umbilical cable in uniform current cable from the composition of the underwater remotely operated vehicle (ROV). The remotely operated vehicle is used in different undersea operation when it is important to control and determine precisely the disturbance forces ...

Voltages and AC Corrosion on Metallic Tubes in Umbilical Cables Caused by Magnetic Induction From Power Cable charging Currents [PDF]
, 2018 Offshore umbilical cables often include both power cables and elements such as metallic tubes and signal cables. It was concluded from a recent failure of stainless tubes that AC corrosion was the failure cause.
