Calculation of Vibrations in a Tethered Underwater Vehicle–Umbilical Cable System
Journal of Machinery Manufacture and Reliability, 2020This article highlights the main factors that determine the oscillation process of an umbilical cable–tethered underwater vehicle system. Cable systems are widespread in various fields of technology: aircraft cable rigging, parachute systems, suspension bridge supports, marine terminal cables, and so on.

Some Problems Involving Umbilicals, Cables and Pipes
1985During recent years a number of companies have grown up in the Aberdeen area designing and developing diving bells, mobile diving units (MDU’s), remotely operated inspection vehicles etc. to meet the increasing need for subsea inspection of pipelines and other offshore installations.

Three-Dimensional Dynamic Behavior of the Flexible Umbilical Cable System
Applied Mechanics and Materials, 2013We 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 ...

Design and installation of subsea cable, pipeline and umbilical crossing interfaces
Engineering Failure Analysis, 2017Abstract Deterioration of subsea cable, pipeline and umbilical crossings often occur due to relative movement between the crossing members. Any crossing design should aim to achieve a sound, fit for purpose solution that will be maintenance free over the crossing life.

Passive damping to attenuate snap loading on a ROV umbilical cable
Proceedings of OCEANS '93, 2002Summary form only given. Snap loading of the umbilical cable connecting a ship to a remotely operated vehicle (ROV) and its cage is a major problem when the ROV system is operating in rough sea conditions. Snap loading is the instantaneous, high magnitude, tensile loading of a cable.

Finite Element Analysis of Umbilical Cables Anchoring Systems Including Frictional Contact
Volume 5: Pipelines, Risers, and Subsea Systems, 2018The armor pots on an umbilical system are critical accessories that are subjected to high tensile loads. To ensure tensile resistance to an umbilical cable connection, its structural elements must be properly anchored to the armor pot. One way to provide that connection is the use of the adhesive properties of an epoxy resin.

Precise Stochastic Fatigue Life Assessment of Umbilicals and Power Cables
Offshore Technology ConferenceAbstract Increasing activity within offshore wind energy and related installations has raised the focus on the integrity and fatigue life of power cables and umbilicals. A limiting factor for assessing fatigue life has been the lack of efficient and precise computational tools that are not overly conservative.

Bitumen is commonly used as anticorrosion protection for armor wires in subsea power cables, umbilicals, and power umbilicals. Bitumen’s viscoelastic behavior influences the cable’s mechanical properties. The present paper derives a simple, analytical model of bitumen-coated armor wires.
