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.

Volume 2: Subsea Technology; Ocean Space Utilization
Free spans on slender subsea structures laying on the seabed such as flexible pipeline, umbilical and cable might develop due to various reasons, e.g., seabed unevenness, scouring, crossing and end terminations, etc. Due to lack of direct guidance, the

Automatic Control and Guidance Method of ROV with Umbilical Cable
IFAC Proceedings Volumes, 2007Abstract For the remotely operated vehicle (ROV) with an umbilical cable, it becomes difficult to guide it to a target as the depth increases. Especially, the vehicle for the working in the deep sea under current disturbance, the control to reach the target is the most important and difficult problem, because the tension of the umbilical cable, which

Choice of Umbilical Cable for Submersibles - Footprint Optimization
Offshore Technology Conference, 1982Abstract The limits of the operational area of a ROV (Remotely Operated Vehicle) are calculated when it is working at a certain water depth. The boundary of the operational area is called the footprint and is depending on the thrust which can be delivered by the submersible, the current velocity, the water depth and

Coupled Thermo-Elastic Analysis on Cross-Section of Umbilical Cables
Volume 5A: Pipelines, Risers, and Subsea Systems, 2019Abstract Umbilical cable is composed of electronic cables, optical cables, steel tubes and structural strengthening components, which can be regarded as a key industrial equipment integrating mechanical and electronic functions.

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.
